Description

The utility model is a sprayer, which mainly provides a structure with convenient assembly, easy replacement of parts and low price, and a commercially available check valve is arranged in the valve seat.

Spray water feeders are commonly used for cleaning vehicles, doors and windows of homes, and spraying operations for orchards, farmland, and flowers. The general types of spray water feeders are mostly as shown in Figure 4. A motor drives a set of pressurizing devices 50 to pressurize , water is introduced by the water inlet housing 52 of the sprayer 51, and is sent out through the water outlet 541 of the lower seat 53 and the upper seat 54. Because when the water outlet 541 is closed, the pressurizing device 50 still continues to pressurize and cause the upper seat 54 to be damaged due to excessive pressure, or force the compression cylinder to fail to move and damage the motor. Therefore, a pressure relief device is arranged in the upper seat 54 so that the water can Release from the pressure relief water outlet 542 above to reduce the excessive pressure inside the upper seat 54, so the design of the pressure relief device of the sprayer 51 is extremely important.

And the structure of existing sprayer 51 has various, and wherein also has approved new-type patent in Taiwan, as shown in Figure 5 is the application number No. 73201241 " safety valve automatic pressure relief device ", Figure 6 is an addition to the second case of the "automatic pressure relief device for high-pressure power sprayer" of the application number No. 76203414, both of which have different structures and the same effect, but each has its own advantages Not perfect.

The following is a description of the structure, action and lack of the two: as shown in Figure 5, the pressurized water flows into the valve chamber 62 of the upper seat 60 from the water inlet 61 of the upper seat 60, and then is supported by the top of the valve seat 63. The water port 632 on the periphery of the body 631 flows into the valve seat 63, then pushes away the inner steel ball 634 supported by the ball spring 633, then flows through the through hole 635 below the valve seat 63, and then releases spray water from the water outlet 64. When the water outlet 64 is closed, the pressurizing device continues to pressurize, so the water flow continues to flow in, and when the water pressure in the valve chamber 62 exceeds the pressure set by the upper pressure adjustment spring 65, the pressure relief steel ball 66 will be pushed away. , so that it leaves the channel 671 of the stop ring 67, and exposes the gap, so that the water flows through the channel 671 and then released from the upper drain port 68, so as to reduce the pressure in the valve chamber 62, so that the whole group of valve seats 63 are received by the lower valve chamber The water pressure of 62 rises and supports steel ball 66.

However, in the water delivery process, due to the continuous stamping of the top ball spring 633, the elasticity is fatigued and the inner steel ball 634 cannot be supported, resulting in water leakage, so that the valve chamber 62 below the valve seat 63 cannot accumulate pressure, so that the steel ball 634 cannot be pushed and leaked. The pressure effect is greatly reduced. This kind of elastic fatigue is a normal physical phenomenon, but because the top ball spring 633 and the inner steel ball 634 are arranged in the valve seat 63, and the upper end is closed by the supporting body 631, when the function of the check valve disappears , the whole set of valve seat 63 must be replaced, but because this kind of valve seat 63 is not a standard product, it cannot be removed and replaced from other places temporarily, and the product must be purchased at a dealer, but there are many places where power sprayers are used For villages and mountains, it may take many days to buy back the valve seat, and the work must be stopped in the middle, so it is not in line with the timeliness, and because it is a non-standard product, the price is quite high, which is undoubtedly a waste for consumers. a burden.

And another sprayer pressure relief structure shown in Figure 6, the pressurized water flows into the first valve chamber 72 from the water inlet 71, pushes the lower valve plate 82 through the valve hole 81 on the valve seat 80, and flows into the second valve chamber. The valve chamber 73 then flows into the valve seat 80 from the perforation 83 on the periphery of the valve seat 80, and then flows out from the channel 741 of the water outlet housing 74 below. When the channel 741 is closed, the pressurizing device continues to pressurize. When the water pressure increases to To a certain extent, the upper steel ball 75 will be pushed away from the spacer ring 76 to release the water. At this point, the pressure in the first valve chamber 72 will decrease, and the shuttle body 84 held under the steel ball 75 will be received by the second valve. The pressure in the chamber 73 resists and rises together with the steel ball 75 . The shuttle body 84 is clamped on the top of the valve seat 80 by means of the stoppers 841 protruding from both sides above to prevent the shuttle body 84 from falling into the valve seat 80 . When the shuttle body 84 pushes upwards, it can rely on the retaining portion 841 to be stuck on the bottom of the spacer ring 76 as a limit of a stroke. But no matter whether the retaining portion 841 directly passes through and is positioned on the shuttle body 84, or the two sides are respectively welded on the shuttle body 84, in the process of processing, due to personnel manipulation factors or problems of processing machinery and jigs themselves, left and right sides will be caused. The inclination and unequal height of the retaining portions 841 on both sides causes the shuttle body 84 to incline slightly and cannot move up and down smoothly in the valve seat 80 .

On the other hand, since its components include a spacer ring, shuttle body, valve seat, valve plate and spring, etc., there are many components, and except for the spacer ring, other components need to be installed from the bottom of the housing, resulting in difficult installation.

And the above-mentioned two types of sprayer pressure relief structures that have been approved for patents all have one thing in common, that is, the valve body used to lift and hold the upper steel ball is a special product. When damaged, the valve body made by the original factory must be used. It is expensive and must be purchased before it can be replaced, which causes delays in work and is quite uneconomical.

In order to improve the lack of the pressure relief structure of the existing sprayer, the main purpose of this utility model is to provide an improved sprayer device, which has the characteristics of easy assembly, low price, and easy replacement to avoid work delays.

In order to achieve the above object, the utility model provides an improved sprayer device, which is mainly provided with a valve chamber with an opening facing upward on the upper seat of the sprayer. An adjustment seat is connected to the top, and an adjustment spring is arranged in the adjustment seat to suppress a steel ball valve, and the lower part of the steel ball valve is clamped by a channel of the resisting ring on the upper side of the valve chamber. There is a channel communicating with the water inlet chamber of the upper seat, and a chamber communicating with the water outlet is provided at the bottom of the valve chamber, and a valve seat that can be moved up and down is provided in the valve chamber, and a spring is provided in the valve seat. The one-way valve of the valve seat is provided with a channel above the valve seat, and several radial valve holes are provided on the periphery of the channel, and a push rod is provided on the top of the valve seat to support the steel ball above. The channel extends downward integrally to a downwardly opening valve-holding chamber. The inner diameter of the valve-holding chamber is relatively large, and a check valve and a spring are set inside it sequentially from top to bottom. An anti-leakage collar is set outside the horizontal flange, and the spring is supported under the horizontal flange of the check valve and under the anti-leakage collar and between the chambers, and a collar is set in the middle of the valve chamber. The top end of the collar is clamped on the bottom edge of the counter ring, while the bottom end is clamped on the inner wall of the valve, and an appropriate distance is kept from the surrounding wall of the lower shaft hole of the valve seat, and the inner diameter of the collar is smaller than the outer wall of the lower shaft hole below. diameter, and a radial through hole matching with the passage of the valve chamber is provided on the peripheral wall of the collar.

The utility model has the following advantages:

1. Easy to assemble: Since the utility model only sets a check valve and a spring under the valve seat, and sets a ring in the valve chamber, and its assembly method is from top to bottom, it is very easy to control, and its parts It is less than the existing structure, such as the shuttle body, valve seat, valve plate, spring, etc. with the retaining portion in the existing structure are not provided in this application. It is quite inconvenient to install under the body. In comparison, the top-down assembly method of the utility model is more convenient.

2. Low defect rate: Since the check valve of the present invention does not need to be processed and assembled, it can be used directly after repurchase, so it can reduce the defect rate caused by personnel negligence or mechanical equipment during manufacturing.

3. Parts are easy to replace, which can improve economic benefits: since the one-way valve used in the utility model is the same as the one-way valve at other valve ports of the sprayer, when the one-way valve is damaged, other one-way valves can be replaced first The use of the valve will not delay the work due to waiting for the valve seat, so the economic benefit can be improved.

4. The parts are cheap: because the one-way valve used in the utility model is a commercially available standard product, its price should be cheaper than the customary special valve seat, so as not to cause a burden on consumers.

Please refer to Fig. 1, 2 and 3 at the same time, the utility model establishes a valve chamber 101 with an opening facing upwards on the upper seat 10 side of the sprayer, and the valve chamber 101 top is closed by an upper casing 11 with a drain port 111, and the upper An adjustment seat 12 is connected to the top of the housing 11 , and an adjustment spring 121 is provided in the adjustment base 12 to suppress the pressing rod 13 disposed in the upper housing 11 . A steel ball valve 14 is pressed under the pressure rod 13, and the lower part of the steel ball valve 14 is clamped on a channel 151 of an abutment ring 15. The abutment ring 15 is located above the valve chamber 101. The creative features of the present invention are:

A radial channel 102 is provided on the upper side of the valve chamber 101 to communicate with the water inlet chamber 103 in the upper seat 10 . In addition, a chamber 104 with a smaller inner diameter is arranged below the valve chamber 101 , and the chamber 104 communicates with the water outlet 105 of the upper seat 10 . In addition, a movable valve seat 20 is provided between the channel 102 of the valve chamber 101 and the lower chamber 104 . The stepped valve seat 20 is provided with a communicating channel 21 and a valve containing chamber 22 . And several through radial valve holes 23 are set on the periphery of the channel 21 . The top of the valve seat 20 is provided with a push rod 24 to push the steel ball 14 above. The inner diameter of the valve-holding chamber 22 opening downward is relatively large, and the inside is provided with a check valve 30 and a spring 31 sequentially from top to bottom, and the upper periphery of the check valve 30 is set as an outwardly protruding horizontal flange 301 , and the horizontal flange 301 is sleeved by a leak-proof collar 302, and the spring 31 is supported under the horizontal flange 301 and the leak-proof collar 302 of the check valve 30 and between the chamber 104, so that the entire valve The seat 20 is subjected to an upward supporting force, so that the push rod 24 located on the top is supported below the steel ball 14 at any time, and the check valve 30 can only allow water to flow downward and cannot return. It is the same as the one-way valve at each valve port of the sprayer, that is, the top planar blocking piece 304 is pushed up by the supporting spring 303 with a smaller elastic coefficient in the one-way valve 30 .

In addition, a collar 40 is set in the middle section of the valve chamber 101. The top of the collar 40 is clamped on the bottom edge of the ring 15, and the bottom edge is clamped on the inner wall of the valve chamber 101, and is connected with the lower shaft hole 22 surrounding wall of the valve seat 20. Keep an appropriate distance, and the inner diameter of the collar 40 is smaller than the outer diameter of the surrounding wall of the lower shaft hole 22 below, that is, when the valve seat 20 moves upward to be blocked by the bottom edge of the collar 40 and cannot continue to rise, it becomes the upward displacement stroke of the valve seat 20. limit point. In addition, a radial through hole 401 is provided on the peripheral wall of the collar 40 to match the channel 102 of the valve chamber 101, so that the pressurized water flow can enter the water chamber 103 from the upper seat 10 through the valve chamber 101, the channel 102, and the through hole of the collar 40. 401 flows into the valve chamber 101.

When the water outlet 105 of the sprayer is opened and the pressurizing device of the sprayer is activated, the pressurized water will enter the water inlet chamber 103 through the water inlet 106 below the upper seat 10, and then pass through the valve chamber The channel 102 of the peripheral wall of 101, the through hole 401 of the collar 40, and then enter the valve chamber 101, then flow into the channel 21 through the valve hole 23 of the peripheral wall above the valve seat 20, and flow downwards into the chamber 104 through the one-way valve 30, and then Released from the water outlet 105. When the water outlet 105 is closed but the pressurizing device is not closed, the water flow continues to flow into the valve chamber 101 and the chamber 104 below the valve seat 10, and when the water pressure increases to a pressure greater than the pressure set by the adjustment spring 121 above, The water pressure will push the steel ball 14 away from the channel 151 of the counter ring 15, so that the water in the valve chamber 101 flows through the channel 151 of the counter ring 15, and then is released from the drain port 111. Therefore, the pressure of the chamber 104 below the valve seat 20 is Greater than the pressure above the valve seat 20, the valve seat 20 and the steel ball 14 move upward together.

It can be seen from the above that the utility model has very few components and is easy to assemble, and the one-way valve it is equipped with is a standard part and has the same structure as the one-way valves arranged on other valve ports. When it is damaged due to long-term use, other one-way valves that are not used temporarily can be replaced, and because the one-way valve is an easily available standard product, the price is low, far cheaper than the aforementioned special valve body .
