Description

A toilet water tank, a water tank piston rod, and a hydraulic control valve

technical field

The invention relates to the field of toilets, in particular to the toilet in the patent application publication number: CN104264756A.

Background technique

In the toilet water tank in the above patent, there is friction between the piston and the inner wall of the tank during the use of the water tank, so it is inevitable that there will be leakage in the seal between the piston and the tank body. When the toilet is in a static state, if the water tank has the leakage, the water tank will have water through the water outlet. The pipes flow out, resulting in wasted water.

In the toilet tank, the water on both sides of the piston needs to circulate. The valve holes and pipes on the water inlet circulation pipes of the water tank are relatively thin. The water circulating in the water tank passes through the valves and pipes. If there are impurities in the water, it is easy to block the valves and pipes. , and the water passing through the valve is always in one direction, the blocked valves and pipes are difficult to get the water to flow freely, and in most cases, it will become more and more blocked, affecting the normal use of the water tank.

In the toilet water tank of the above-mentioned patent, the piston rod is an integral structure, so it is relatively long and takes up more space, and the piston rod goes out of the water tank cylinder. A certain resistance is not conducive to use and affects the service life. If the water tank wants to adjust the maximum amount of water, it is more difficult. The length of the pull rod extending out of the cylinder will change, and there will be potential collisions with the water tank components around the pull rod.

The above patent, the water tank outlet pipe is thick and has a certain length, the water outlet pipe is thick and the valve volume is large, if the water tank and the water outlet pipe valve are installed on the ground around the squatting pan, urinal, or around the toilet, the installation is more complicated, and It seems that there are many things around the toilet and it is not convenient to repair the water tank and valve. If the water tank is installed on the wall around the toilet, the water inlet and outlet pipes between the valve on the ground and the water tank take up a lot of space and the pipes are long. Will reduce flushing pressure.

For the water tank valve installed on the ground, when the valve pressure conduction plate rises and falls, there will inevitably be gaps between the conduction plate and the surrounding ground, and dust and water droplets on the ground will inevitably enter the gap, causing the hidden danger of valve failure, and the gap may also be safe hidden danger.

SUMMARY OF THE INVENTION

The invention is a toilet water tank blocking device, which solves the problem of leakage of water in the water tank when the toilet is stationary, and also solves the problems that the water tank valve is easy to block and difficult to unclog.

In the present invention, a water flow channel 51 or a water flow gap that penetrates the piston is arranged on the piston, or a water flow gap is arranged between the water tank cylinder and the piston, so as to realize the circulation of water on both sides of the water tank piston. Two seals to solve the leakage when the water tank is idle. The water flow gap includes the concave or gap that penetrates the piston at the edge of the piston and other positions, and also includes the gap between the piston and the piston on the inner wall of the upper section 52 in the cavity during the movement of the water tank cavity. When the piston reaches the bottom of the water tank cavity, there can be a gap or no gap between the inner wall of the bottom section 53 of the cavity and the piston. If there is a gap, the water tank needs to be sealed by a piston sealing device. If there is no gap, the piston and the inner wall of the cavity can be directly realized seal. When the piston is in the cavity, there may be a gap between the piston and the inner wall of the upper section of the cavity, and there is no gap between the piston and the inner wall of the bottom section of the cavity. There may be no gap between the inner wall of the cavity bottom section 53 and the piston.

The water flow gap also includes a water flow gap that appears between the vertical rod and the through hole when the vertical rod 54 in the water tank cavity is located in the piston through hole.

Piston water flow gap or water flow channel 51, when the water tank is filled with water, the water on the piston side of the water tank will flow from the side with more water to the side with less water, and when the water tank is flushed, there will also be water from the side with more water to the side with more water. On the side with less water, the direction of water passing through the water gap or water channel is different twice, and the gap or water channel is surrounded by the water tank cavity space, which is much larger than the pipe space around the valve, so the piston water gap or water channel is not easy to block. , When the water tank is filled with water, the water on both sides of the piston circulates through the water flow gap or the water flow channel of the piston, which has the advantage of not being easily blocked. A vertical rod 54 is arranged in the water tank cavity, the water tank piston has a through hole, the vertical rod passes through the through hole, and the through hole and the through hole of the piston form a water flow gap. During the movement of the piston, water flows on both sides, and the vertical rod is at the position of the through hole of the piston. Constantly changing, it is not easy to block.

If the water flow gap or water channel of the piston needs to achieve a lower water flow per unit time, the gap formed by the vertical rod and the piston through hole is easier to realize, and the smaller area gap formed by the vertical rod and the piston through hole is easier to complete.

During the drainage and flushing process of the water tank, the flow rate per unit time is much smaller in the water gap or channel compared with the toilet outlet main pipe and water outlet pipe. During the flushing process, the water on the side of the piston water outlet main pipe will also pass through the piston water flow gap in a small amount. Or the water channel, reaching the other side of the piston, the water output of the toilet can increase the maximum volume of the water tank according to the needs, so the water gap or the water channel will not affect the normal flushing of the toilet.

The second seal of the water tank is to set a blocking device 50 on the other side of the piston rod. When the water tank is idle, the blocking device contacts with the port 8 of the main pipe of the water tank to block the main pipe of the water tank.

The toilet water tank includes a water tank body 9, a first water inlet pipe 2, a second water inlet pipe 3, a water outlet pipe 7, a water tank trunk pipe 8, a piston 11, and a piston rod. The water tank also includes a blocking device 50, the piston is located in the In the water tank cavity, the piston and the inner wall of the water tank cavity are the piston and cylinder structure, the upper part of the piston is connected with the piston rod, the piston rod passes through the upper bottom of the water tank, and the blocking device is connected with the piston without the piston rod end or is arranged at the bottom of the water tank, The upper bottom of the water tank cavity is connected with the water inlet pipe 2, the lower bottom of the water tank cavity is connected with the main pipe 8, the water outlet pipe 7 and the water inlet pipe 3 are connected with the main pipe. When the water tank is idle, the piston is located at the bottom of the water tank, blocking the The device is in contact with the 8 ports of the main pipe of the water tank, or the blocking device is in contact with the piston to block the main pipe of the water tank. The piston pull rod includes two or more pull rods passing through the bottom of the tank and two or more pull rods located in the water tank box.

In order to make the water flow on both sides of the piston inside the water tank all flow through the water flow gap or water channel of the piston, and prevent the water inlet pipe and valve of the water tank from being blocked, a one-way valve is set on the first water inlet pipe 2, and the first water inlet pipe can only enter water. .

The cross section of the plunger of the toilet water tank of the present invention can be cylindrical, cylindrical or oval, and the blocking device can be a part of the piston or the pull rod or an independent part.

The tie rod of the water tank piston of the present invention is a telescopic structure with more than two sections and is a multi-stage telescopic structure, and the tie rod may not extend out of the cylinder barrel or partially extend out of the cylinder barrel. The length of the pull rod of the toilet water tank of the invention is obviously shortened, which greatly saves space, and at the same time, the pull rod does not extend out of the cylinder barrel or partially extends out of the cylinder barrel, which reduces the friction force, is beneficial to use, and is beneficial to improve the service life.

The invention is to install a protective cavity for the tie rod of the water tank piston, which prevents the tie rod from colliding with the water tank components and prevents the tie rod from being scratched after being stretched out.

By adjusting the length of the bolt entering the cavity, the maximum telescopic distance of the pull rod can be adjusted, so as to adjust the maximum amount of water added to the water tank.

By controlling the amount of lubricant in the cavity, the maximum telescopic distance of the pull rod can also be controlled, thereby adjusting the maximum amount of water added to the water tank.

After the tie rod extends out of the cylinder, the tie rod is protected by the cavity, and is glued with lubricant. When it is retracted, the friction force is reduced, which is beneficial to the use and prolongs the service life.

The invention also solves the deficiencies in the background technology of the toilet tank pressure control valve.

The valve of the present invention has a sealed cylinder and piston structure, and the pressure of the circulating medium itself is required to generate force on the piston in the valve cavity to open or close the valve; at the same time, the valve state will be changed by the external force, and the external force action mode has a direct action mode and indirect action.

Valves include normally open valves and normally closed valves.

The normally open valve includes a pressure conduction plate 81, a tie rod 82, a spring 88, a valve cavity 86, a piston 87, a medium inlet pipe 84, a medium outflow pipe 85, and a pipe plug 83, the piston is located in the valve cavity, the piston and the valve cavity It is a sealed cylinder piston structure, the upper bottom of the piston is connected with the tie rod, the tie rod is pierced from the upper part of the valve cavity, the top of the tie rod is connected with the pressure conduction plate, the outer sleeve of the tie rod has a spring, the lower bottom of the piston is connected with the pipe plug 83, and the pipe plug moves down ( Axial movement) can seal the medium flowing out of the pipeline.

The normally open valve can cancel the spring 88. The piston 87 and the valve cavity are the structural features of the sealed cylinder piston. After the piston moves down, the upper bottom of the piston and the upper part of the valve cavity will form a vacuum state. After the pressure of the pressure conduction plate disappears, the atmosphere The pressure will push the piston back up, and at the same time, the downward movement of the piston will be resisted by atmospheric pressure; it can also prevent the upper bottom of the piston 87 and the upper part of the valve cavity from forming a vacuum, and there are air holes at the top of the valve to allow the gas to flow. When 83 moves down to the lowest position, the medium outflow pipe 85 is blocked, the valve cavity filled with medium has pressure, the normally open valve piston 87 is subjected to the upward pressure of the medium, and when the pressure on the pressure conduction plate 81 disappears, the upward pressure of the medium makes The piston returns to the highest position.

The normally closed valve can cancel the spring 88, and use the piston 87 and the valve cavity to be a sealed cylinder piston structure. After the piston moves down, the upper bottom of the piston and the upper space 111 of the valve cavity will form a vacuum state. After the pressure of the pressure conduction plate disappears , the atmospheric pressure will push the piston back up, and at the same time, the downward movement of the piston will be resisted by atmospheric pressure. It is also possible to make the upper bottom of the piston 87 and the upper part of the valve cavity not form a vacuum, and there are air holes at the top of the valve to allow the gas to circulate. When the second pipe plug 110 of the normally closed valve moves down to the lowest position, the medium outflow pipe 85 is opened, The valve cavity filled with the medium has pressure, and the normally closed valve piston 87 is subjected to the upward pressure of the medium. When the pressure on the pressure transfer plate 81 disappears, the upward pressure of the medium makes the piston return to the highest position

The above valve structures are all external force acting directly on the valve, and the external force also acts indirectly on the valve.

There can also be air holes in the upper part of the cylinder, which is a non-vacuum area.

The improved hydraulic device is connected with a vertical shaft 142 under the second piston 115. The vertical shaft passes through the lower bottom of the cylinder. The vertical shaft and the second tie rod have the same axial direction, and the two are concentric or the same shaft together with the second The fixed connection of the piston and the function of the vertical axis make the upward and downward moving trajectory of the second tie rod have better concentricity, thereby preventing the downward movement from offsetting and increasing the resistance of the downward movement. Moreover, with the increase of the vertical axis, under the same pressure in the cylinder, The resistance of the second piston to move downward can be reduced.

When the second pipeline plug is in the closed state of the highest position, the lower end section is sealed with the cavity or a neck portion 138 of the medium outflow pipeline correspondingly. In the middle of the second pipe plug, there is a thin part. When the second piston and the second pipe plug are forced to move down, the thin part of the second pipe plug just reaches the cavity or a neck part of the medium outflow pipe and between them A gap will appear, and the normally closed valve will open. At this time, the upward restoring force of the second pipe plug and the second piston by the pressure medium is less than the downward pressure on the piston. If the control valve does not use hydraulic pressure, the control valve is the normally open valve. It is characterized in that: the control valve no longer includes the hydraulic device and the hydraulic medium pipeline 116, including the pressure conduction plate 81 and the pull rod 82, the top of the cavity is sealed, the lower end of the pull rod is connected with the piston, the pull rod passes through the top of the valve cavity, and the top of the pull rod is connected to the piston.

At this time, the upward restoring force of the second pipeline plug by the pressure medium is less than the downward pressure on the piston. If the control valve does not use hydraulic pressure, the control valve is the normally open valve, which is characterized in that: the control valve no longer includes hydraulic pressure.

The hydraulic device also includes a hydraulic device with a bladder structure. The device includes a plastic bladder, a capsule body, a leather bladder, leather, cloth materials, metal materials, and variable volume bladders made of synthetic materials. valve is connected.

The compressed volume and volume of the bladder are reduced. After the pressure of the bladder disappears, the valve piston is controlled to recover, so that the hydraulic medium flows back to the bladder, and the shape and volume of the bladder return to the original state.

The above is the simple structure of the valve that communicates with the hydraulic control device. If the media on both sides of the piston 87 in the simple structure are different, the media on both sides will contaminate each other under the condition that the piston is not tightly sealed.

However, if the hydraulic medium and the medium circulating in the valve cavity are not afraid of mixing, or can be mixed within a certain proportion, the hydraulic control device has a new role. When the valve is a toilet flush valve, the hydraulic medium of the hydraulic control device is detergent, the valve piston 87 is not afraid of leakage, and a circulation hole is set on the piston 87, so that the toilet flush can enter a certain amount of detergent, there will be good The result is a cleaner toilet flush. In order to prevent the reduction of the detergent stock in the hydraulic control device from affecting the use, the hydraulic medium pipeline is communicated with the detergent container 123, and the detergent container can be filled with detergent. In order to make the mixing effect of detergent and water better, the hydraulic medium pipeline and the medium in the detergent container should maintain a certain pressure.

In order to eliminate this shortcoming of possible contamination, the following is an upgraded valve that communicates with the hydraulic control device.

The valve of the upgraded structure adds a small cylinder on the basis of the original valve having a cavity. The small cylinder includes a cavity 120, a piston 121, and a piston rod. The cavity is connected to the hydraulic medium pipeline, and the piston rod is connected to the valve rod. 82 connection, there is a hydraulic medium 117 circulating between the cavity on the other side of the piston rod and the piston, there can be a connecting part 122 between the small cylinder and the valve, or the small cylinder and the valve can be fixed separately to make the hydraulic control device pressurized , the pressure to the movement of the piston 121 becomes the movement of the valve piston 87 in the valve cavity.

In the hydraulic valve of the invention, the hydraulic medium pipe is much thinner than the water outlet pipe of the water tank, which can make the space around the toilet more spacious, the water tank inlet and outlet pipes and valves can keep the closest distance from the water tank, and the location selection is more convenient, as long as the hydraulic medium pipe and the water tank The valve can be connected. In this way, the adjacent water tank and its valve can be well insulated together in the outdoor with low temperature. This is compared with the distance between the water tank and the water tank valve, and the valve, water tank and pipeline must be insulated. More beautiful and lower cost, because the hydraulic medium of the hydraulic control valve has good frost resistance and does not need to be insulated.

The invention also discloses a decoration and decoration method for the control valve: firstly, the control valve is fixed in a designated pit hole, and the pit is surrounded by the ground, and then the pressure transmission plate of the hydraulic device or other pressure transmission end faces or the surface of the bladder is decorated, The decoration material is covered, the decoration material is connected to the ground around the decoration material, and the decoration material is bonded or pressed on the ground with fasteners such as screws.

The back of the decoration and decoration material is close to or close to the pressure conduction plate or other pressure conduction end face or the surface of the bladder. When an external force acts on the hydraulic device, the hydraulic device enters the working state, the external force disappears, and the hydraulic device returns to the static state.

The decoration and decoration material can be pasted, printed, pressed and engraved with patterns.

The decoration and decoration method of the control valve can prevent the gap between the conduction plate and the surrounding ground, prevent dust and water droplets on the ground from inevitably entering the gap and cause the hidden danger of valve failure, and prevent the potential safety hazard in the gap.

The decoration and decoration materials are pasted, printed, pressed and engraved patterns, which can improve the aesthetics of the ground.

The present invention can well solve the deficiencies and defects existing in the prior art.

It is characterized in that the water tank also includes The plugging device, the sealing ring 4 and the sealing ring slot, the plugging device is a plunger structure 10, the piston is located in the water tank cavity, the inner wall of the piston and the water tank cavity is a piston and cylinder structure, and the upper part of the piston is connected with the piston rod, The piston rod passes through the upper bottom of the water tank, the upper bottom of the water tank is connected with the water tank cavity by the water inlet pipe 2, the lower bottom of the water tank is connected with the main pipe 8, the water outlet pipe 7 and the water inlet pipe 3 are connected with the main pipe. When the water tank is at the bottom, the plunger is located at the lower part of the piston, and there is a sealing ring slot on the main pipeline at the bottom of the water tank. The sealing ring is installed in the slot, and the plunger and the sealing ring are correspondingly sealed. There are two or more tie rods passing through the bottom of the tank body and two or more tie rods located in the tank body of the water tank.

The second sealing method is: the blocking device is set as a ring of protrusions on the lower bottom of the water tank, the water tank includes a ring of elastic protrusions 20, and the elastic protrusions are located at the bottom of the water tank. When the piston is located at the bottom of the water tank, the The elastic protrusion and the lower bottom of the piston are corresponding seals.

A ring of protrusions 20 included in the water tank may not be an elastic protrusion, and the corresponding sealing surface is elastic.

When the toilet water tank is stationary, the water tank piston is located at the bottom end of the water tank, and the pressure on the upper surface of the piston makes the piston tightly press the elastic seal on the bottom of the water tank to form the second seal of the water tank.

The third sealing method is to set a ring of protrusions 55 at or around the end of the plugging device to seal against the position outside the main pipe opening at the bottom of the water tank to block the main pipe. Alternatively, the blocking device is set as a ring of protrusions on the lower bottom of the piston, the water tank includes a ring of elastic protrusions 55 located on the lower bottom of the piston, and the elastic protrusions are correspondingly sealed with the lower bottom of the water tank. The diameter of the circle of protrusions may be large or small.

A ring of protrusions 55 included in the water tank may not be an elastic protrusion, and the corresponding sealing surface is elastic.

When the toilet water tank is stationary, the water tank piston is located at the bottom end of the water tank, and the pressure on the upper surface of the piston makes the seal on the bottom of the piston press tightly with the bottom of the water tank to form the second seal of the water tank.

The fourth sealing method is: the blocking device is a second plunger structure 30, and the water tank configuration includes a conical or conical second plunger structure 30, a conical or conical slotted hole, and the conical or conical The second plunger structure is located at the lower part of the piston, and the main pipe on the lower bottom of the water tank has a conical or conical slotted hole, and the conical or conical second plunger structure is correspondingly sealed with the conical or conical slotted hole.

When the toilet water tank is at rest, the water tank piston is located at the lowest end of the water tank, and the pressure on the upper surface of the piston makes the conical or conical second plunger structure at the lower part of the piston tight with the conical or conical slot hole on the main pipe at the bottom of the water tank Press together tightly to form a second seal for the tank.

The fifth sealing method is: the blocking device is a columnar structure, and a self-recovery opening valve is set in the main pipeline of the water tank. When the water tank is idle or the water flows through, the valve is open. When the water tank is flushed to the bottom of the last water tank piston When it moves to the bottom, the cylindrical structure of the piston blocking device contacts the valve, and the water pressure continues to push the piston down, so that the cylindrical structure of the blocking device moves down to close the valve. When the water tank is filled with water, the piston moves up and the valve opens automatically.

When the water tank is flushed, the blocking device moves downward from the upper part of the water tank, and finally the main pipe of the water tank is sealed and stationary. When there is leakage between the piston and the inner wall of the toilet, the leaked water is blocked by the blocking device in the water tank.

When the water tank starts to work next time, the water inlet pipe valve 5 is opened, and the water outlet pipe valve 6 is closed, and the water tank will have two situations:

In the first case, if there is leakage between the piston of the water tank and the inner wall of the water tank, the water pressure on both sides of the piston is equal and there is circulation. Under the pressure on the upper part, the piston starts to move upward, the water tank starts to add water, and the blocking device is not blocking the main pipeline of the water tank.

In the second case, if there is no leakage between the water tank piston and the inner wall of the water tank, the water pressure on both sides of the piston is equal but there is no circulation. The pressure on the upper part of the piston, the piston starts to move upward slightly, and then the pressure at the lower part of the piston of the water tank will be less than the pressure on the upper part of the piston and the water pressure of the water inlet pipe 3 on the end face of the plunger, and the water passes through the second water inlet pipe 3. The device or the sealing ring enters the tank, the water tank starts to work with water, and the blocking device leaves the sealing ring.

Connection, the first-stage tie rod 63 is connected to the piston 61, and the end of the third-stage tie rod 65 is connected to the bottom of the cylinder. When both sides of the piston are filled with pressure water flow, the piston does not have the water pressure area on the tie rod side, and the tie rod side receives water pressure. Compared with the area, it needs some more area.

When the piston is moved by water pressure, the friction parts will be lubricated by water during the mutual expansion and contraction of the pull rods at all levels. Compared with the expansion and contraction of the pull rod of the water tank in the background technology, the friction force is reduced, which is beneficial to the use and the service life. .

(2) The specific embodiment 2 of the telescopic rod of the water tank:

The toilet tank with the integral pull rod extending out of the cylinder

The stage tie rod 68 is connected with the piston 66, and the end of the eighth stage tie rod 70 penetrates the bottom of the cylinder barrel and can be extended and retracted in the cylinder barrel. When the two sides of the piston are full of pressure water flow, the piston has no water pressure area on the side of the tie rod, and is connected to the side of the tie rod. Compared with the water pressure area, at least an area equal to the cross-sectional area of the sixth-stage tie rod 68 is required.

When the piston is moved by water pressure, during the mutual expansion and contraction of the tie rods at all levels, the friction between the sixth tie rod 68 and the seventh tie rod 69 will be lubricated by water. When the sixth tie rod 68 and the seventh tie rod 69 After retracting into the eighth-stage tie rod 70, the piston 66 continues to move to the side where the eighth-stage tie rod 70 passes through the cylinder, and finally reaches the maximum stroke range, which is the longest distance that the eighth-stage tie rod 70 can extend out of the cylinder. .

Compared with the expansion and contraction of the water tank tie rod in the background art, the frictional part between the sixth stage tie rod 68 and the seventh stage tie rod 69 will be lubricated by water. Compared with the expansion and contraction in the cylinder, the friction force is also reduced, which is beneficial to use and prolongs the service life.

The protective cavity 73 of the water tank pull rod of the present invention has one end connected to the water tank 75 and the other end sealed. The protective cavity can cover the extended piston pull rod, and the other end is provided with an adjusting bolt 71. After the water tank pull rod extends out of the cylinder, the extension The end of the drawn rod just contacts the end of the adjusting bolt in the cavity 73, and the water tank has the maximum amount of water. If the length of the adjusting bolt entering the cavity is increased, the length of the rod extending out of the cylinder is shortened, and the maximum amount of water to be added to the water tank is reduced. .

There is a lubricant adding pipeline 72 in the cavity 73, the pipeline 72 can be installed with a valve, and the lubricant 74 can be added through the cavity 73 of the pipeline 72. After the tie rods are all extended out of the cylinder, the space occupied by the extended tie rods is a fixed maximum value. The cavity is filled with lubricant. Since the lubricant is difficult to be compressed, after the tie rod is retracted into the cylinder, a certain amount of lubricant or water that does not affect the lubrication effect of the lubricant is added to the cavity, and the valve of pipeline 72 is closed. When the cylinder tie rod is extended again, the cavity has no space for accommodating all the extended tie rods, and the extension distance of the tie rods becomes smaller, thereby realizing the purpose of adjusting the maximum water addition amount of the water tank.

The protective cavity 73 of the water tank pull rod of the present invention has the same function for the two-stage or more telescopic piston pull rods extending out of the cylinder in the present invention.

3. The specific implementation of the water tank control valve:

Pipe 85, the valve is closed, when the pressure of the pressure transfer plate disappears, the medium pressure in the valve will have an upward force on the piston, the piston is simultaneously subjected to the upward restoring force of the spring and the upward force of the atmospheric pressure, the piston and the pipe plug move up, and the valve opens.

When the valve is directly closed, there is a pressure medium in the valve cavity, the second pipe plug 110 and the piston are located at the highest position that the upper part of the valve can reach, the piston is simultaneously elastically elastically upward by the spring, and the pressure medium in the valve cavity exerts an upward force on the piston. The pipe plug 110 can seal the outflow pipe of the medium. When the pressure transmission plate is forced to move down, the piston and the second pipe plug move down at the same time. The second pipe plug 83 is no longer blocking the outflow pipe 85, and the valve is opened. disappears, the medium pressure in the valve will have an upward force on the piston, the piston is simultaneously subjected to the upward restoring force of the spring and the upward force of the atmospheric pressure, the piston and the second pipe plug move up, and the valve is closed.

When the hydraulic control device is used, the pressure conducted by the hydraulic medium 117 works in the same principle as the pressure conducted by the valve pull rod and the pressure transfer plate.

When there is a force and pressure transmission plate 113, the piston pushes the hydraulic medium 117 and the pipe 116 into the valve cavity 86, the piston 87 moves downward, and the movement of the valve piston 87 drives the pipe plug 83 or the second pipe plug 110 or two pipe plugs to move , the valve is closed or opened. When the pressure of the second conduction plate disappears, due to the upward force of the pressure medium in the valve on the piston 87, the vacuum area between the piston 115 and the cylinder 114 has negative pressure, and the hydraulic medium passes through the valve cavity through the hydraulic medium. Line 116 flows back to the hydraulic controls and the valve is opened or closed.
