Description

Technical Field

[0001] The utility model relates to the technical field of control valves, and more specifically to a multifunctional water pump control valve. Background Art

[0002] In modern water treatment and fluid transmission systems, water pumps are core power equipment, and their stable operation and efficient control are crucial. Traditional water pump control valves have a single function and are difficult to cope with complex and changeable working conditions. For example, problems such as medium backflow and water hammer impact occur frequently, affecting system safety and efficiency. Traditional water pump control systems mostly rely on manual operation or simple automatic control methods, which are complicated to operate and prone to errors. The gate valve is usually in a closed state. When the water pump is started, the gate valve opens slowly. When the water pump is stopped, the gate valve closes quickly first, and then slowly closes to a certain extent. The closed gate start and closed gate stop of the water pump can effectively prevent water hammer when the pump is started and stopped. At the same time, it reduces the motor load when the water pump is started. The shaft power of the water pump is the smallest at zero flow, generally only 30% of the designed shaft power. Another function of the gate valve is that when the gate valve is closed, it can provide safe maintenance conditions for valves and water pumps such as the check valve installed between the gate valve and the water pump to prevent water backflow in the pressure water pipe.

[0003] Insufficient existing technology: Traditional water pump control valves have a single function and are difficult to cope with complex and changeable working conditions. When the drainage volume is large, a control valve often has only one drain port. When the drainage demand is large, one drain port is not enough, or a control valve has multiple outlets but cannot be controlled individually, which can easily cause excessive drainage. Therefore, common control valves cannot control the drainage volume well. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a multifunctional water pump control valve to solve the problems existing in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional water pump control valve, comprising an inner hollow threaded tube, the top end of the inner hollow threaded tube is fixedly connected to a control disc, the inner ring side wall of the inner hollow threaded tube is threadedly connected to a telescopic threaded tube, the bottom end of the telescopic threaded tube is fixedly connected to a sealing plugging block, the top end of the sealing plugging block is fixedly connected to a retaining rod, and the bottom of the sealing plugging block is fixedly connected to a rubber sealing ring.

[0006] Furthermore, a retaining hollow tube is movably sleeved on the outer ring side wall of the retaining rod, a sealing top cover is fixedly connected to the top of the retaining hollow tube, and a fixed rocker block is fixedly connected to the top of the sealing top cover.

[0007] Furthermore, the outer ring side wall of the sealing top cover is movably sleeved with a main shell, and the inner cavity of the main shell is fixedly connected with an inner through pipe.

[0008] Furthermore, a first water outlet is opened on the side of the inner through pipe, a limiting sealing ring is fixedly connected to the inner circle side wall of the inner through pipe, and a top end of the sealing top cover is threadedly connected.

[0009] Furthermore, a fixing nut is threadedly connected to the bottom of the top of the main shell, an additional pipe outlet pipe is fixedly connected to the side of the main shell, and a second water outlet pipe is fixedly connected to the side of the main shell.

[0010] Furthermore, an interface ring is fixedly connected to the side of the second water outlet pipe, an interface hole is opened on the side of the interface ring, and an interface pipe is fixedly connected to the bottom of the main body shell.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model is provided with an additional pipe water outlet, a first water outlet and a second water outlet pipe, so that the two water outlets can output water to two places respectively, thereby improving the flexibility of the water supply system. When a water outlet has a problem or needs maintenance, the other water outlet can still work normally, thereby ensuring the continuous supply of water. Different fire fighting or water supply places may have different demands for water sources. In some occasions, it may be necessary to take water from two water outlets at the same time to meet the demand. The design of two water outlets can better adapt to these diverse needs.

[0013] 2. The utility model controls the sealing plugging block by providing an inner through pipe and the hole opened on its side, the sealing plugging block and the operating disc, which is beneficial to the control of the drainage volume. When a large amount of drainage is not required, the sealing plugging block is adjusted to facilitate the control of the drainage volume. By adopting technical principles such as slow opening, fast closing and slow closing, the water pump control valve can gradually adjust the flow rate and pressure of the fluid in the pipeline when the water pump is started and stopped, thereby greatly reducing the damage of water hammer to pipelines and equipment.

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The multifunctional water pump control valve involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0020] Reference Figures 1 to 4 The utility model provides a multifunctional water pump control valve, including an inner hollow threaded tube 2, a control disc 201 is fixedly connected to the top of the inner hollow threaded tube 2, a telescopic threaded tube 202 is threadedly connected to the inner ring side wall of the inner hollow threaded tube 2, a sealing plugging block 203 is fixedly connected to the bottom end of the telescopic threaded tube 202, a retaining rod 204 is fixedly connected to the top of the sealing plugging block 203, and a rubber sealing ring 205 is fixedly connected to the bottom of the sealing plugging block 203. By rotating the control disc 201 fixed on the inner hollow threaded tube 2, the thread transmission causes the telescopic threaded tube 202 to move. The shrink threaded tube 202 moves up and down in the inner cavity of the inner tube 108, thereby driving the sealing block 203. When the sealing block 203 moves to the lowest end, the rubber sealing ring 205 fixed at the bottom of the sealing block 203 will be connected to the groove at the top of the limiting sealing ring 110, which will block the water flow and prohibit drainage. The rubber sealing ring 205 is conducive to being able to fit tightly at the interface that needs to be sealed, effectively preventing the leakage of liquid, gas or solid particles. Its good elasticity and resilience ensure that a stable sealing effect can be maintained under different working conditions.

[0021] Among them, the outer ring side wall of the retaining rod 204 is movably sleeved with a retaining hollow tube 107, the top of the retaining hollow tube 107 is fixedly connected with a sealing top cover 105, and the top of the sealing top cover 105 is fixedly connected with a fixed rocker block 103. The retaining rod 204 and the retaining hollow tube 107 are sleeved with each other, which is beneficial to prevent the sealing blocking block 203 from rotating at will, so that it can only move up and down.

[0022] Among them, the outer ring side wall of the sealing top cover 105 is movably connected with the main shell 1, and the inner cavity of the main shell 1 is fixedly connected with an inner tube 108. The side wall of the inner tube 108 is provided with four water outlets, and is also connected to an additional pipeline outlet pipe 101 for controlling two different water flow sizes.

[0023] Among them, a first water outlet 109 is opened on the side of the inner tube 108, and the inner circle side wall of the inner tube 108 is fixedly connected with a limiting sealing ring 110, which is conducive to the sealing blocking block 203 reaching a certain position and contacting with the limiting sealing ring 110, thereby blocking the water flow, and the top of the sealing top cover 105 is threadedly connected with 104.

[0024] Among them, the top and bottom of the main shell 1 are threadedly connected with a fixing nut 106, the side of the main shell 1 is fixedly connected with an additional pipe outlet pipe 101, and the side of the main shell 1 is fixedly connected with a second water outlet pipe 3. The two water outlets can output water to two places respectively, which improves the flexibility of the water supply system. When a water outlet has a problem or needs maintenance, the other water outlet can still work normally, thereby ensuring the continuous supply of water. The two water outlets can achieve balanced distribution of water flow, reduce the water hammer phenomenon caused by water flow changes, and protect equipment such as pipes and valves from damage.

[0025] Among them, an interface ring 301 is fixedly connected to the side of the second water outlet pipe 3, an interface hole 302 is opened on the side of the interface ring 301, and an interface pipe 102 is fixedly connected to the bottom of the main shell 1.

[0026] The working principle of the utility model is as follows: by rotating the control disc 201 fixed on the inner hollow threaded tube 2, the threaded transmission causes the telescopic threaded tube 202 to move up and down in the inner cavity of the inner through tube 108, thereby driving the sealing block 203. When the sealing block 203 moves to the lowest end, the rubber sealing ring 205 fixed at the bottom of the sealing block 203 will be connected with the groove at the top of the limiting sealing ring 110, which will block the water flow and prohibit drainage. The control disc 201 is rotated again to make the sealing block 203 move upward and move to the top of the first water outlet 109, and the water will flow into the main water outlet through the first water outlet 109. The inner cavity of the body shell 1 flows out through the second water outlet pipe 3 fixedly connected to the main body shell 1. When a large amount of water is needed, the rotating control disc 201 moves the sealing blocking block 203 to the top. At this time, the water will not only flow into the second water outlet pipe 3 from the inner cavity of the main body shell 1 and flow out, but also flow into the additional pipe water outlet pipe 101 through the inner cavity of the inner through pipe 108 and the outlet connected to the additional pipe water outlet pipe 101, thereby increasing the drainage volume. When it is needed to be used in multiple occasions, the additional pipe water outlet pipe 101 and the second water outlet pipe 3 can be connected to different pipes respectively to discharge water into different positions.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
