Valve and valve structure device

Technical field

The invention relates to the field of delay valve and toilet valve application technology and valve control device for liquid and gas passage.

Background technique

In the existing published toilet patent, the delay valve structure of the toilet water pipe is relatively complicated, and the delay time is not well grasped. The delay valve used in other liquid and gas media also has this phenomenon, and now some gas extensions The valve structure is also complicated, and relays are usually used. In addition, when two sets of pipes are currently controlled, two valves are usually used, and the structure is complicated.

At present, most toilet flushing is pure water use, sometimes the cleaning effect is not very good, especially for some toilets without water traps, in addition to the poor cleaning effect at that time, the toilet pipe will have a bad smell for a long time. Cleaning the dirty toilet is easy to breed bacteria, and flies are prone to occur in summer. Sometimes some public toilets add decomposition additives to people's excrement.

The present invention is more suitable for a toilet in the patent application of the prior art, which is hereby incorporated by reference.

Summary of the invention

The invention comprises a time delay valve and a valve structure device. The time delay valve comprises two structures: a time delay closing valve and a time delay opening valve. The time delay valve can make the water (or other liquid or gas) entering the time delay valve be set. After the time, the discharge is stopped, the delay is turned off, or the discharge is started after the set time has elapsed, and the delay is opened. The time delay valve and the valve structure device can better control the moving speed of the valve plug through the size of the gap between the shaft hole of the valve plug and the shaft hole, and realize the delay valve or the valve structure device after the set time, complete the work, set A good, standard time-delay valve with good time, the set time can also be adjusted in a small range by the delay valve tension spring.

Let's take water as an example to introduce the delay valve and valve structure.

The time-delay closing valve includes two structures A and B.

The A structure includes a valve A cavity 204, an A valve plug 205, an A valve plug shaft hole 206, a first A water inlet (gas) pipe 211, a second A water inlet (gas) pipe 213, and an A water outlet (gas) pipe 210. , A link 209, A cross bar 201, A tension spring 202, A shaft rod 203 in the cavity, the A valve plug 205 is installed in the cavity body, the A valve plug has an A valve plug shaft hole 206, A link One end is connected with the A valve plug, the other end is connected to the A cavity, the top end is connected with the A cross bar, and the A cross bar and the A end of the A time delay valve have two A tension springs, and the time delay valve A is fixed at the top end of the cavity. The shaft 203 and the lower end of the A-axis rod are located in the shaft hole of the A valve plug, and the A-axis rod and the A-valve shaft hole are gap-fitted, and the time-out valve A outlet pipe port is at a higher position on the side of the delay valve, and the time delay valve When stationary, the A valve plug is located at the bottom of the time delay valve. The A valve plug 205 also has an A through hole 208. The A through hole has an A check valve 207. The medium can flow from bottom to top, but the medium cannot be used. When the A valve plug reaches the highest position of the valve cavity, the side of the A valve plug covers and seals the A water (gas) pipe, and the A structure delay valve is closed.

The first A and second A inlet (gas) pipes may be used simultaneously or only one of them may be retained. When only the second A inlet (gas) pipe 213 is retained and used, the A check valve has a larger water passage area than The area of the second A water inlet (gas) pipeline 213 is the same pressure and time, and the A check valve water quantity is greater than the second A water inlet pipe 213.

A negative pressure valve 214 can also be installed at the bottom of the A structure time delay valve. When the time delay valve is stationary, the A-axis rod is slightly thinner in the A-valve shaft hole. When it is stationary, there is a slight gap between the lower end of the A-axis rod and the A-valve shaft hole. The A-valve through-hole 208 is around the upper opening. The surface of the whole valve plug is relatively concave. If the time delay valve enters the impurity, the impurity will easily reach the recess A, the valve plug through hole 208, the gap between the A shaft and the A valve plug shaft hole, and then reach A. At the bottom of the cavity, a pipe is connected to the bottom of the A cavity to connect the A negative pressure valve 214. The bottom surface of the time delay valve cavity where the pipe mouth is located is recessed than the surrounding area, and impurities passing through the through hole are also relatively easy to pass through the pipe to reach A negative. The pressure valve is discharged through the pipeline under the A negative pressure valve, or stays at the A negative pressure valve. Even if the impurity does not reach the A negative pressure valve, the impurity will not block the A shaft when the time delay valve is next water. The water gap between the shaft holes of the A valve plug is also easily discharged from the water outlet pipe together with the water flow.

The A-axis rod 203 can also be fixed at the bottom end of the cavity of the time-delay valve A, and is located in the A-valve shaft hole of the corresponding position.

The outlet of the valve B outlet pipe is at a higher position on the side of the time delay valve. When the time delay valve is stationary, the B valve plug is located at the bottom of the time delay valve, the B valve plug 225 has a B through hole 228, and the B through hole has a B one-way. Valve 227, the medium can pass through the B check valve faster from bottom to top, but the medium Can not pass from top to bottom, when the B valve plug reaches the highest position of the valve cavity, the side of the valve plug covers and blocks the B water (gas) pipe, and the B structure delay valve is closed.

The third B and fourth B inlet (gas) pipes may be used simultaneously or only one of them may be retained. When only the fourth B inlet (gas) pipe 233 is retained and used, the B check valve has a larger water passage area than The area of the 233 port of the fourth B water inlet (gas) pipeline is that the water flow of the B check valve is greater than the water volume of the fourth B water inlet pipe 233 under the same pressure and time. When the valve is normally used, the inlet pipe outlet area is larger than the outlet pipe. Crossing area.

When the B valve plug shaft hole is located just below the B valve plug link 229, the B through hole 232 and the B through hole are part of the B valve plug shaft hole 226, and the B shaft rod is used together to realize the water circulation above and below the B valve plug; If the B valve plug shaft hole 226 is not located just below the B valve plug link 229, the B valve plug shaft hole directly penetrates the upper surface of the valve plug, and the B valve plug shaft hole and the B shaft rod are correspondingly located at the B valve plug link. In the periphery, the B-axis hole directly penetrates the upper surface of the valve plug, and the water above and below the B valve plug flows through the gap between the B-axis hole and the B-axis rod.

The B structure delay closing valve is equipped with a B negative pressure valve 234, and the B negative pressure valve is the same as the time delay closing valve A structure A negative pressure valve.

When the valve A and B are closed for a delay, the working principle of the water (gas) pipe is as follows:

If the valve is closed, the inlet water (gas) pipe under the valve plug is used. When the valve is stationary, the valve plug is located at the bottom of the valve. When the pressure medium enters the water inlet pipe, the medium quickly passes through the valve plug through hole and the check valve. Above the valve plug and into the water outlet pipe, since the upper surface of the valve plug is simultaneously subjected to the downward pressure of the pressure medium, the pressure on the lower surface of the valve plug is slightly larger than the pressure on the upper surface, and the valve plug moves slowly upward under the action of the pressure medium. The pressure medium in the space above the valve plug in the valve cavity is slowly circulated back to the bottom of the valve plug through the gap between the shaft and the valve plug shaft hole. As the cavity space above the valve plug is reduced, the valve plug slowly moves up and seals. The water outlet pipe is blocked and the valve is closed for a delay. When the valve inlet pipe pressure disappears, the medium under the valve plug quickly reaches the top of the valve plug through the check valve due to the return valve spring return force valve plug down, and the valve plug returns to the bottom of the cavity, and the valve inlet and outlet pipes are connected.

If the valve is closed, the inlet (water) pipe on the valve plug is used. When the valve is stationary, the valve plug is located at the bottom of the cavity. When the pressure medium enters the water inlet pipe, the medium quickly enters the water outlet pipe, and the medium passes through the shaft. The gap between the valve plug and the through hole slowly reaches the bottom of the valve plug, but the medium cannot pass through the through hole and the check valve reaches the bottom of the valve plug. The lower surface of the valve plug is simultaneously subjected to the upward pressure of the medium, and the pressure on the lower surface of the valve plug is higher than that. The pressure on the surface is slightly larger, the valve plug moves up slowly under the action of the pressure medium, the space above the valve plug becomes smaller, the valve plug continuously moves up and blocks the water outlet pipe, and the valve realizes a time-delay closure. When the pressure of the water inlet pipe of the time delay valve disappears, the medium below the valve plug quickly reaches the top of the valve plug through the one-way valve due to the spring return force, and the valve plug returns to the bottom of the cavity, and the valve enters and exits the water pipe.

In the plug shaft hole, the shaft rod and the valve plug shaft hole are clearance fit, and the outlet (gas) pipe port is located on the side of the time delay valve. When the time delay valve is stationary, the valve plug side covers and blocks the water (gas) pipe or does not Cover and block the outlet (gas) pipeline, located at the bottom of the time delay valve, there is a through hole in the valve plug, there is a check valve on the through hole, the medium can flow from bottom to top, but the medium can not flow from top to bottom When the valve is filled with water (gas), there are pressure differences between the upper and lower surfaces of the valve plug, and the upper and lower parts of the valve plug The water (gas) of the cavity flows through the gap between the shaft and the valve plug shaft hole, and the valve plug moves to the connecting rod side. After a certain time, the valve plug moves a certain distance, and the state between the valve outlet pipe and the water inlet pipe changes. The valve is opened or closed. After the water (gas) pressure of the inlet valve disappears, the valve plug returns to the original position by the spring restoring force or the gravity of the valve plug itself.

The time delay valve of the invention is suitable for use in a liquid medium such as water, and is also applicable to various gas media, and can also be used in combination of gas and liquid.

The water inlet pipe of the time delay valve of the invention may be one, or one of the upper end cavity and the lower end cavity of the valve plug, and no flow regulating valve is installed on the water inlet pipe to control the rising speed of the valve plug, and the rising speed of the time delay valve of the invention Mainly through the gap between the shaft and the through hole of the valve plug, the speed of the water flow of the valve plug is controlled, and the gap length between the shaft and the valve plug moves with the valve plug. Changes, and the valve plugs reach a specific position, the medium passing between them will be replaced by a larger through hole or the entire valve plug through hole. The difference in diameter between the delay valve shaft and the valve plug shaft hole can be controlled to about 0.05 mm. Assuming that the shaft rod and the valve plug shaft hole diameter difference is 0.05 mm, the gap between the shaft rod and the valve plug shaft hole is S1, in the gap. In the case, the flow rate of the water in the valve plug is relatively slow. If the time delay valve cancels the shaft and directly sets the through hole with the through hole area S1 on the valve plug, the through hole is relatively small, if the time delay valve The inlet water has smaller impurities to enter, and it is easy to block the valve plug shaft hole, causing the delay valve to malfunction.

The above description is based on the fact that the cross section of the delay valve shaft and the plug shaft hole is circular, and the cross section also includes shapes other than a circle, such as an ellipse, a triangle, a rectangle, a polygon, and a partial circular or elliptical shape. The composite shape, the cross section is other than the circular shape, assuming that the total area of the gap between the shaft and the valve plug shaft hole is still S1, the impurities in the water are also not easy to block the valve plug shaft hole.

For the time interval between the valve plug shaft hole and the shaft in the time delay valve and the valve structure device, one or several gaps 50 between the valve plug and the inner wall of the chamber may be replaced. Taking the structure of the time delay valve C as an example, the position of the gap 50 should be avoided to intersect the time delay valve outlet passage 40. Compared with the through hole on the valve plug, the total area of the gap can easily realize the above S1 area size. Moreover, the gap will change position and is not easy to block. Moreover, the gap 50 can realize the area and length of the valve plug moving process, which is beneficial to realize the uniform movement of the valve plug, so as to better control the precise movement of the time delay valve and the device. .

For the time delay valve of the present invention, in the case where the pressure of the water inlet (gas) pipe of the time delay valve is constant, the size of the gap between the shaft hole of the valve plug and the shaft determines the speed of the medium circulation of the valve plug, thereby realizing the extension. When the valve opens the water (gas) pipe delay time, if the gap between the valve plug shaft hole and the shaft is very small, the time delay valve can realize the time of delay opening, accurate to a few tenths of a second, through Adjust the medium pressure, tension spring force, the gap between the delay valve shaft and the valve plug shaft hole, the relative movement distance between the shaft rod and the shaft hole set, and the time delay valve can realize the control of the relay and the supporting electrical components. This is especially important in the absence of electrical energy.

If the time delay valve linkage is above the valve plug, after the pressure of the medium entering the time delay valve disappears, the downward return of the valve plug can be moved downward by the gravity of the valve plug, and the tension spring on the time delay valve is cancelled.

The valve structure device of the invention has the same structure and working principle as the time delay valve, and the pressure difference between the upper and lower sides of the valve plug is caused to make the valve plug flow up and down (gas) from the gap between the shaft rod and the valve plug shaft hole, so that the valve plug moves. The pressure inside the device disappears and the valve plug returns to its original position.

When the device is stationary, the valve plug is located at the bottom of the valve cavity, and the valve plug 54 has a pass. The hole 62 has a check valve 63 on the through hole, and the one-way valve realizes that the medium flows from bottom to top and cannot flow from top to bottom.

When the valve plug shaft hole is just below the connecting rod 52, a section of the through hole of the connecting portion of the connecting rod and the valve plug has a through hole 64, and the through hole is part of the valve plug through hole 58, and the water above and below the valve plug Through the through hole and the gap between the valve plug shaft hole and the shaft; if the valve plug shaft hole is not located just below the valve plug link, the valve plug shaft hole directly penetrates the upper surface of the valve plug, the valve plug shaft hole and The shaft rod is correspondingly located at the periphery of the valve plug connecting rod, and the valve plug shaft hole directly penetrates the upper surface of the valve plug, and the water above and below the valve plug directly flows through the gap between the shaft hole of the valve plug and the shaft rod.

After the valve structure device enters the pressure medium, the bottom force of the valve plug is greater than the upward resistance of the valve plug, the valve plug moves upward, and the connecting rod is located above the valve plug. After the medium pressure entering the device disappears, the valve plug can be recovered downward by the gravity of the valve plug. Moving, the valve plug is returned downwards by means of a link mounting spring outside the device.

The inlet (gas) pipe in the valve structure device can be at the upper end of the cavity, the lower end, or the upper and lower sides. The shaft rod in the cavity can be in the upper part of the cavity or in the lower part of the cavity.

The valve structure device can realize the change of the distance between the device link and the device cavity under the action of the pressure medium, thereby further realizing the force of the device on a specific article, or realizing a specific signal through the movement of the device, and the force of the device on the article. Or the signal sent out can control the speed and time very well, and after the pressure disappears, the device can recover itself.

detailed description:

In the following, when the working medium of the time delay valve is water, the C structure delays the use of the valve.

When the pressure water flow enters the time delay valve cavity from the water inlet pipe, the water flow can flow through the gap between the shaft and the valve plug shaft hole, and the through hole 44 flows, and the water pressure of the lower surface of the valve plug of the time delay valve is greater than The surface is subjected to the sum of the water pressure and the tension of the tension spring. The valve plug is pushed up by the water pressure. When the valve plug rises to the highest position, the water outlet pipe covered by the valve plug and blocked is completely covered by the valve plug at rest. The valve inlet and outlet pipes are fully connected.

When the water just enters the time delay valve cavity, if there is no water above the valve plug, the maximum water inlet speed of the inlet pipe is less than the maximum water passing speed of the check valve, and the water flow first reaches the upper space of the valve plug through the one-way valve, and the upper air pressure and The water pressure in the chamber is equal. When the pressure water flowing into the valve plug is not available, the valve plug is quickly recovered by the restoring force of the tension spring 31, and the water under the valve plug quickly passes through the check valve 43 to reach the valve plug, and the valve plug quickly returns to the bottom of the time delay valve. The valve plug covers and blocks the water outlet pipe 40.

Toilet valve embodiment 1:

The toilet pipe and the water tank add detergent valve, which mainly comprises a valve cavity 113), a valve lower fixed seal 107), a valve water inlet pipe 108), and also includes a plunger 111), a plunger upper hole 104), a valve cavity The upper part of the body fixed seal 102), the spring 112), the peripheral cavity of the valve bottom seal 107) communicates with the toilet tank water inlet pipe 109), the lower end of the valve plunger passes through the lower end of the valve seal 107), and the lower end of the plunger has a cavity 104. The surface of the plunger where the cavity is located is relatively smooth, and the upper portion of the valve plunger passes through the upper fixed seal 102), and the valve cavity 113) is divided into the upper cavity 101) and the central cavity 103 by the upper seal 102). The top of the valve plunger protrudes more than one turn from the upper middle portion, and a spring 112) is mounted between the upper seal 102) and the top of the plunger. The lower end of the spring bears against the upper seal 102), and the upper end of the spring bears against the top of the plunger. An extra ring protrudes from the upper portion, and when the valve is stationary, the valve central cavity 103) at the position of the cavity above the plunger stores detergent, and the valve inlet pipe 108) is the same as the water inlet pipe 109).

The valve at the lower end of the valve seal 107) can be connected to the toilet inlet pipe or the toilet outlet pipe, and can also communicate with the toilet tank. When the toilet inlet or outlet pipe is pressurized, the water or toilet tank is added to the toilet. While the toilet water is used, the pressurized water of the valve pipe 108) exerts a downward thrust on the upper end of the valve plunger. If the valve is in communication with the toilet water supply pipe or the toilet water tank, the downward thrust of the upper end of the valve plunger is greater than the spring. 112) The elastic force is the sum of the water pressure of the water inlet pipe or the toilet water tank received by the lowermost end of the valve plunger, the plunger is pushed downward by the water, and the plunger cavity is filled with the detergent in the middle cavity 103), the plunger belt The detergent reaches the water tank inlet pipe 109) or the toilet tank, and the detergent in the plunger hole 104) is dissolved and absorbed by the water. At this point, the position where the lowermost end of the plunger reaches is best not to be touched. The toilet is inserted into the inner wall of the water pipe or the inner wall of the water tank to prevent damage during the touch process.

The top of the valve plunger is circled to form a piston and cylinder structure that can be sealed with the inner wall of the valve chamber to reduce the erosion of water on the protruding spring or other position, and the protrusion can also have a gap with the inner wall of the valve chamber. As long as the plunger receives a downward water pressure greater than the sum of the spring 112) spring force and the inlet pipe or toilet tank water pressure received at the lowermost end of the valve plunger.

During the passage of the plunger cavity through the lower end seal 107) until the cavity reaches the inlet pipe 109) or the toilet tank, the volume of the valve plunger in the central cavity 103) becomes larger, and the detergent in the central cavity 103) can pass. The detergent pipe 116) is transferred outwardly so as not to hinder the downward movement of the plunger 111), or a volumetric elastic device is added to the central cavity, or the central cavity detergent is kept under a state of dissatisfaction. The plunger down process is not obstructed by the central cavity 103).

After the valve inlet pipe 108) pressure disappears, the downward pressure of the water received by the plunger disappears, the spring 112) restoring force causes the plunger 111) to move upward, and the plunger cavity is retracted to the middle cavity through the lower end seal 107) body. When returning to the middle cavity, if the plunger cavity is retracted from the toilet tank inlet pipe or the toilet tank, the plunger cavity will bring the water back to the middle cavity. After such a long time, the detergent concentration in the middle cavity Will be greatly reduced, need to replace the detergent, if the detergent valve is connected with the toilet outlet pipe, the valve plunger will not bring the water to the middle cavity, then the detergent is sent to the toilet outlet pipe, the detergent dissolution effect is compared Slightly worse.

Another seal 105) and a water outlet 117) may be disposed in the valve chamber, the seal 105) being located between the lower end seal 107) and the upper seal 102), the seal 105) and the lower end seal 107), and the inner wall of the chamber forming a valve The lower chamber 106), the lower end of the valve plunger passes through the seal 105), and the outer wall of the valve lower chamber 106) between the seal 105) and the lower end seal 107) has a water outlet 117), the valve is at rest, the plunger The location of the upper hole is above the seal 105). The detergent valve having the lower cavity 106), during the retraction of the valve plunger, the plunger cavity first reaches the lower cavity 106), the cavity 106) is empty, and the water in the cavity is in the cavity 106) Will quickly flow down, and then the cavity passes through the seal 105) to the upper cavity 103), the water flowing to the cavity 106) will flow out from the water outlet 117), increasing the valve of the cavity 106), the cavity 130) The detergent will bring a small amount of water into the plunger cavity, and the detergent will not need to be replaced.

Valves can be added with different amounts of detergent according to the size of people's convenience. First, several holes are placed from the bottom to the top of the valve plunger. The height of each plunger is lower than the thickness of the lower seal 107). The plunger 111) has a certain gap between the top of the plunger and the inner wall of the valve, or a through hole 110 at the top of the plunger, or the top of the plunger protrudes from the inner wall of the valve chamber while the top of the plunger There are also through holes.

Before the convenience of the person, the toilet is stationary, and the upper cavity 101) of the upper part of the plunger is filled with water. When the person is convenient, the water flows through the pipe 108) into the upper cavity 101), and the water pressure causes the plunger to move downward, and the plunger The water that protrudes from the circle must flow Moving to the top of the protrusion, the plunger can move downward, and the size of the gap between the plunger and the inner wall of the valve chamber or the size of the through hole 110) determines the velocity of the water protruding from the upper and lower positions, which determines The speed at which the plunger moves down. When a person urinates, the water pressure acts on the valve plunger for a short period of time. The water that protrudes from the plunger reaches less water above the protrusion, and the distance that the plunger moves downward is smaller, so that only the lower position is The plunger cavity carries the detergent to the water inlet pipe or the water tank or toilet drain pipe. When a person has a bowel movement, the water pressure acts on the valve plunger for a long time. The water protruding from the plunger reaches the water above the protruding one, and the distance that the plunger moves downward is maximized, so that all the plunger holes are completed. Bring the detergent to the water inlet pipe or the water tank or toilet drain.
