Description
Technical Field
[0001] This utility model relates to the field of fluid control technology, and in particular to a leak-proof water pump valve structure. Background Technology
[0002] With the acceleration of industrialization, pumps and valves have been widely used in water treatment, petrochemicals, power, HVAC, and civil buildings. In these applications, pumps and valves usually need to operate efficiently for a long time to ensure that the fluid control and transmission of the device does not leak. However, due to pressure fluctuations, temperature changes, aging of sealing materials, and valves not closing tightly, pumps and valves are prone to liquid or gas leakage during operation, resulting in energy waste, equipment damage, pollution, and even safety hazards.
[0003] A pump valve consists of a valve body, valve seat and valve disc, and a drive unit. The valve body (or pump body) serves as the main housing, carrying the fluid and providing a flow path. The valve body design must have good structural strength to prevent pressure and corrosion. The valve seat and valve disc are key components for controlling fluid flow. The tightness of the valve seat and valve disc directly affects the sealing performance. They are usually made of wear-resistant and corrosion-resistant materials. The drive unit is used to operate the pump valve and must have a leak-proof design to ensure that no leakage occurs during operation.
[0004] However, in some existing valves, liquid backflow occurs during actual operation. Liquid backflow not only seriously affects the normal operating efficiency of the equipment, but also leads to pressure imbalance in the device, and may even cause equipment failure, resulting in incalculable economic losses. Therefore, a leak-proof pump valve structure is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a leak-proof water pump valve structure, which aims to improve the problem of liquid backflow in some valves in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A leak-proof water pump valve structure includes a valve body, a limiting ring fixedly connected to one side of the valve body, a telescopic column fixedly connected to one side of the limiting ring, a baffle fixedly connected to one end of the telescopic column away from the limiting ring, a fixing ring fixedly connected to one side of the valve body, a connecting pipe fixedly connected to one side of the fixing ring away from the baffle, and a control component fixedly connected to the top of the valve body.
[0008] As a further description of the above technical solution:
[0009] The control component includes a connecting block, the top of which is rotatably connected to a valve, and the bottom of which is fixedly connected to the top of the valve body;
[0010] As a further description of the above technical solution:
[0011] Two water pipes are fixedly connected to both ends of the valve body. A connecting ring is fixedly connected to the outside of the water pipes. Multiple limiting balls are set inside the connecting ring. A limiting ring is fixedly connected to one end of the connecting ring. A spring is fixedly connected to one side of the limiting ring. A moving block is fixedly connected to the other end of the spring. A connecting pipe is slidably connected inside the connecting ring.
[0012] As a further description of the above technical solution:
[0013] A spring is fixedly connected to one side of the limiting ring, and the other end of the spring is fixedly connected to the side of the baffle away from the fixed ring.
[0014] As a further description of the above technical solution:
[0015] The side of the baffle away from the telescopic column contacts the side of the fixing ring, and the inside of the second limiting ring contacts the outside of the first water pipe.
[0016] As a further description of the above technical solution:
[0017] The connecting ring has a sealing ring inside, and the outside of the sealing ring is in contact with the inside of the moving block;
[0018] As a further description of the above technical solution:
[0019] One side of the second connecting pipe is fixedly connected to the second water pipe, and the outer side of the first connecting pipe is fixedly connected to the inside of the second limiting ring.
[0020] As a further description of the above technical solution:
[0021] The movable block is slidably connected to the outside of the connecting ring, and the outside of the second connecting tube is in contact with the inside of the limiting ball.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, by opening the valve, the liquid enters the push baffle from the connecting pipe, compressing the spring and the telescopic column, allowing the liquid to flow normally into the valve body from around the baffle. After closing the valve, the liquid inside the valve body pushes the baffle so that its perimeter fits against the fixing ring, effectively preventing liquid backflow and significantly improving the stability and safety of the entire device.
[0024] 2. In this utility model, by pushing the moving block, the locking state of the limiting ball can be released, so that the connecting pipe can be inserted into the moving block. After it is inserted into place, the moving block is released. As the compressed spring pushes the moving block to reset, the moving block moves to the outside of the limiting ball, thereby firmly fixing the position of the limiting ball and the connecting pipe, and smoothly completing the docking of the water pipe and the valve body. This docking method is simple to operate and greatly improves the installation efficiency. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3This utility model provides an embodiment of a leak-proof water pump valve structure, including a valve body 1. A limiting ring 2 is fixedly connected to one side of the valve body 1. A telescopic column 3 is fixedly connected to one side of the limiting ring 2. A baffle 5 is fixedly connected to the end of the telescopic column 3 away from the limiting ring 2. The telescopic column 3 has a telescopic characteristic. When the liquid pushes the baffle 5 to move, the telescopic column 3 can extend and retract with the movement of the baffle 5, playing a supporting and guiding role. The baffle 5 is a key component for controlling the flow of liquid. The baffle 5 can move under the push of the liquid, thereby realizing the control of the liquid flow direction. A fixing ring 6 is fixedly connected to one side of the valve body 1. A connecting pipe 7 is fixedly connected to the side of the fixing ring 6 away from the baffle 5. The connecting pipe 7 is the channel for the liquid to enter the valve body 1. The connecting pipe 7 introduces the external liquid into the interior of the valve body 1 to realize the flow of liquid.
[0033] The fixing ring 6 is used to fix the connecting pipe 7. Simultaneously, when the valve 9 is closed, it cooperates with the baffle 5 to prevent liquid backflow, ensuring the device's sealing. A spring 4 is fixedly connected to one side of the limiting ring 2. The spring 4 is elastic; when the liquid pushes the baffle 5 to move, the spring 4 is compressed, storing elastic potential energy. When the liquid pressure disappears, the spring 4 returns to its original state, pushing the baffle 5 back to its original position. The other end of the spring 4 is fixedly connected to the side of the baffle 5 away from the fixing ring 6. This connection method allows the spring 4 to effectively apply force to the baffle 5, controlling its movement. The side of the baffle 5 away from the telescopic column 3 contacts the side of the fixing ring 6. When the valve 9 is closed, the liquid pushes the baffle 5 from inside the valve body 1, causing the baffle 5 to fit tightly against the fixing ring 6, effectively preventing liquid backflow and ensuring the stability and safety of the entire device's operation, avoiding equipment damage and safety hazards caused by liquid backflow.
[0034] A control component is fixedly connected to the top of the valve body 1. The control component is used to control the flow of liquid, making it convenient for users to operate and manage the entire device. The control component includes a connecting block 8, and a valve 9 is rotatably connected to the top of the connecting block 8. The connecting block 8 connects the valve 9 and the valve body 1, allowing the valve 9 to be stably installed on the top of the valve body 1 and to rotate flexibly. By rotating the valve 9, the liquid passage can be opened or closed, thereby controlling the flow of liquid. The bottom of the connecting block 8 is fixedly connected to the top of the valve body 1, ensuring a firm connection between the connecting block 8 and the valve body 1, and providing a guarantee for the stable operation of the valve 9.
[0035] Reference Figure 1 , Figure 4Two water pipes 10 are fixedly connected to both ends of the valve body 1. These two water pipes 10 serve as the main channels for liquid to enter and exit the valve body 1, ensuring that the liquid flows in an orderly manner in the device. A connecting ring 11 is fixedly connected to the outside of the water pipe 10. A sealing ring 15 is provided inside the connecting ring 11. The sealing ring 15 can effectively prevent liquid leakage at the connection point, improve the sealing performance of the connection, and ensure that the liquid can flow in the predetermined channel without leakage. Multiple limiting balls 14 are provided inside the connecting ring 11.
[0036] Connecting pipe 2 17 is slidably connected inside connecting ring 11. Connecting pipe 2 17 can slide inside connecting ring 11, which facilitates the connection and disassembly of water pipe 2 18 and valve body 1, and improves the flexibility of equipment use. Limiting ball 14 can limit and fix connecting pipe 2 17 when it is inserted into connecting ring 11, ensuring that the position of connecting pipe 2 17 inside connecting ring 11 is accurate and there will be no loosening or displacement. One end of connecting ring 11 is fixedly connected to limiting ring 2 13. The inside of limiting ring 2 13 is in contact with the outside of water pipe 10. Limiting ring 2 13 is used to fix connecting pipe 1 7, and at the same time, it plays a certain limiting role for the components inside connecting ring 11, ensuring that the position of each component inside connecting ring 11 is stable.
[0037] The outer side of the connecting pipe 7 is fixedly connected to the inside of the limiting ring 13. This connection method ensures a firm connection between the connecting pipe 7 and the limiting ring 13, allowing the liquid to smoothly enter the valve body 1 through the connecting pipe 7. A spring 12 is fixedly connected to one side of the limiting ring 13, and a moving block 16 is fixedly connected to the other end of the spring 12. The spring 12 is elastic. When the moving block 16 is pushed, the spring 12 is compressed and stores elastic potential energy. When the moving block 16 is released, the spring 12 returns to its original state, pushing the moving block 16 to reset. Under the action of the spring 12, the moving block 16 can slide outside the connecting ring 11, thereby fixing and releasing the limiting ball 14 and the connecting pipe 17.
[0038] The outer side of the sealing ring 15 contacts the inner side of the moving block 16. When the moving block 16 moves to the outside of the limiting ball 14, the moving block 16 will apply a certain pressure to the sealing ring 15, so that the sealing ring 15 can better perform its sealing function and further improve the sealing performance of the connection. A water pipe 18 is fixedly connected to one side of the connecting pipe 17. The water pipe 18 is used to introduce external liquid into the connecting pipe 17 and then flow into the valve body 1. It is an important channel for liquid to enter the valve body 1. The moving block 16 is slidably connected to the outside of the connecting ring 11. This connection method allows the moving block 16 to slide flexibly outside the connecting ring 11, realize the fixing and loosening of the connecting pipe 17, and facilitate the docking operation of the water pipe 18 and the valve body 1.
[0039] The outside of the second connecting pipe 17 is in contact with the inside of the limiting ball 14. When the second connecting pipe 17 is inserted into the connecting ring 11 at a certain position, the limiting ball 14 will be in close contact with the outside of the second connecting pipe 17, which will limit and fix the second connecting pipe 17, ensuring that the position of the second connecting pipe 17 in the connecting ring 11 is stable and there will be no loosening or displacement, thus ensuring the reliability of the connection between the second water pipe 18 and the valve body 1.
[0040] Working principle: When valve 9 is first opened, liquid enters through connecting pipe 7, which pushes baffle 5. The movement of baffle 5 compresses spring 4 and telescopic column 3, causing the liquid to flow from around baffle 5 into the valve body 1. When valve 9 is closed, the liquid pushes baffle 5 from inside the valve body 1, causing baffle 5 to come into contact with the fixing ring 6, thus preventing backflow of liquid and ensuring the stability and safety of the entire device.
[0041] Before using valve body 1, the movable block 16 can be pushed, so that the inside of the movable block 16 will disengage from the locking ball 14, and then the connecting pipe 17 can be inserted into the movable block 16. When the connecting pipe 17 is inserted to a certain position, the movable block 16 can be released. Since pushing the movable block 16 will compress the spring 12, the spring 12 will push the movable block 16 to move, and then the movable block 16 will move to the outside of the locking ball 14. The movable block 16 will then fix the position of the locking ball 14 and the connecting pipe 17, thus realizing the docking of the water pipe 18 and valve body 1.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
