Description

A siphon with a spool

technical field

The invention relates to a siphon with a valve core for absorbing liquids in various tanks, buckets, cylinders and other containers, which belongs to the optimization technology of siphons.

Background technique

To suck liquid from tanks, barrels, cylinders and other containers, there are generally the following methods: the first is the simplest, insert one end of a hose into the liquid surface, suck the other port with your mouth, and the liquid in the container will flow into it. In the hose, as long as the hose port located outside the container is lower than the liquid level, the liquid in the container will flow into the external container along the hose, thereby establishing a liquid flow channel from the liquid in the container to the hose to the external container . This method is simple and convenient, but the disadvantage is that it is very unhygienic to use the mouth to suck the hose, and the liquid may flow into the mouth. The second is to fill the hose with liquid, block both ends with your fingers, immerse one end in the liquid in the container, and the other end is lower than the liquid level, release your fingers on both sides at the same time, and the liquid in the container will flow smoothly. The disadvantage of this method is that some containers have very small mouths, such as oil drums, and it is difficult to put hands into the container. The third is to set an air bag on the hose, immerse one end of the hose in the liquid, squeeze the air bag with your hands, the liquid level in the container will enter the hose, when the liquid in the hose is enough, Put the other end of the hose below the liquid level, and the liquid will flow into the hose continuously. The disadvantage of this method is that the air bag needs to be squeezed for a long time to establish a flow channel for the liquid.

Therefore, it is necessary to find a simpler siphon with a spool.

detailed description

As shown in Figure 1, Figure 4 and Figure 5, a siphon with a valve core is mainly composed of a valve body 1, a valve core 2 and a mouthpiece 3, the valve body and the mouthpiece are docked to form a cavity, and the valve core is placed in the cavity. The main body of the valve core 2 is a cylinder, and the end surface facing the liquid inlet is conical or hemispherical, so that it can fit the shape of the suction port, and can completely block the suction port, so that the liquid cannot flow in or out through the suction port.

As shown in Figure 2, the valve body 1 is provided with an inwardly narrowed suction port 11 near the liquid inlet, and on the inner wall of the cylindrical part of the valve body, there are more than three suction ports extending from the liquid inlet to the outlet. The rectangular limiting rib 12 of the liquid port is symmetrically distributed on the inner wall of the valve; the maximum outer diameter of the spool is smaller than the diameter of the inner hole defined by the inward end face of the limiting rib, so that the valve core can be positioned at the limiting protrusion. When the valve core moves to the liquid inlet direction and reaches the inner wall of the suction port, the end face of the valve core facing the liquid inlet will completely block the suction port, and the liquid cannot enter and exit the valve through the gap between the valve core and the valve body. body, at this time, a part of the spool is still in the space defined by the limiting ridge, so as to prevent the spool from entering the space between the suction port and the limiting ridge, so that the spool can only move within the space defined by the limiting ridge. The hole and its vicinity move axially, that is, when the valve core blocks the suction port or is held up by the stop rib, a part of the valve core is still in the space limited by the limit rib.

As shown in Figure 3, the part where the nozzle 3 is connected to the valve body is a cylinder with the same diameter as the valve body, and the part toward the liquid outlet is narrowed to form an outwardly protruding joint 31, which is used to connect with the hose. There are more than three stop ribs 32 protruding toward the liquid inlet on the wall of the mouthpiece near the interface facing the liquid inlet. The stop ribs are symmetrically distributed, and the diameter of the valve core is larger than the inner limit defined by the stop ribs. The diameter of the hole, when the spool moves toward the liquid outlet, it will be held up by the stop protrusion, so that the liquid can enter the interface through the gap between the spool and the inner wall of the nozzle.

An inwardly recessed valve slot is provided on the end face of the valve core facing the liquid outlet.

The suction port is conical or arc-shaped, and the diameter of the narrowest part of the inner hole of the suction port is less than half of the diameter of the inner hole of the cylindrical part of the valve body. Before use, connect the interface of the siphon with a hose, and raise the container holding the liquid so that the outlet end of the hose is lower than the liquid level.

When the siphon is quickly pressed into the liquid in the container from top to bottom, the liquid pours into the valve body through the liquid inlet tank and the opening of the valve body, and the poured liquid pushes up the valve core. When the siphon is quickly lifted up , because the valve core is heavier than the liquid and is in a suspended state, under the action of gravity and inertia, the valve core moves downward to block the suction port. When the valve core moves downward, part of the liquid will still flow back into the container, but some Liquid remains in the valve body.

When the spool moved downward, there was also liquid in the valve slot on the upper end surface of the spool, so that the spool was in a stable state, and the suction port could be quickly sealed to prevent the loss of liquid in the siphon. Then press the siphon into the liquid and lift it up again. Repeat this several times, a liquid circulation channel will be established in the siphon and the hose connected to it, so that the liquid in the container will flow continuously along the siphon and the hose. When you want to stop, you only need to lift the siphon and hose from the container to leave the liquid surface, the liquid circulation channel will be destroyed, and the liquid will no longer flow into the siphon and hose. At this time, you only need to increase the siphon With the liquid inlet facing up, the residual liquid in the siphon and hose can flow down.

The edge of the valve body facing the liquid inlet end is provided with a plurality of liquid inlet grooves 13. When the valve body enters the liquid surface, the setting of the liquid inlet grooves can reduce the resistance of the liquid to the valve body.

The end surface of the limiting rib facing the central axis of the valve body is provided with an arc surface coaxial with the central axis of the valve body to reduce the friction between the valve core and the limiting rib, so that the valve core can move more smoothly in the limiting position. movement within the bore defined by the ribs.

The end surface of the limiting rib facing the central axis of the valve body is provided with an arc angle to reduce the friction between the valve core and the limiting rib, so that the valve core can move more smoothly in the inner hole defined by the limiting rib .

The height of the spool is greater than the diameter of the inner hole defined by the limiting ridge, so as to prevent the spool from turning over when the liquid flows, and the spool can only move axially in the inner hole space defined by the limiting ridge.

The diameter of the spool is 1-3mm smaller than the diameter of the inner hole defined by the limiting ridge, so as to prevent the spool from turning over or tilting when the liquid flows. axial movement.

The edge of the stop protrusion facing the liquid inlet is arched, so that the stop protrusion can resist the end surface of the valve core facing the liquid outlet, and at the same time, there is enough gap between the valve core and the mouthpiece for the liquid to flow. Pass.

The valve body is provided with a suction port and a limit protrusion, and a stop protrusion is provided in the mouth, so that the valve core can move between the suction port and the stop protrusion. It will shake from side to side and produce tumbling. The valve core can block the suction port so that the liquid cannot enter and exit. Under the push of the liquid, the valve core can move from the suction port to the direction of the stop protrusion and abut against the stop protrusion.

The siphon is connected to the hose. When in use, the siphon is repeatedly pressed into the liquid in the container and then lifted out of the liquid. The liquid will flow into the hose from the gap between the valve core and the mouthpiece, so that the liquid in the container A liquid communication channel is established between the liquid, the siphon and the hose.

The above-mentioned embodiments are only used to illustrate and explain the purpose of the present invention, rather than to limit the present invention. Those of ordinary skill in the art may make various changes or substitutions within the essential scope of the present invention, which shall also belong to the present invention. scope of protection for inventions.
