Description

Technical Field

[0001] This utility model relates to the field of electric valve technology, and more specifically, to an electric valve that can prevent water leakage at the interface. Background Technology

[0002] Electric valves are widely used in various fluid control systems. They are automatic control valves that use electric actuators to control the opening and closing of the valve. The sealing performance of electric valves and pipeline connections is subject to extremely high requirements.

[0003] A search revealed that Chinese patent CN218377920U discloses an electric valve. Addressing the issue that external contaminants such as moisture and dust can enter the housing through the through-slot on its side, causing corrosion and shortening the lifespan of internal components, the electric valve actuator is modified by placing the manual operating mechanism outside the housing. This eliminates the need for a through-slot on the housing itself. Therefore, the manual operating mechanism does not affect the housing's sealing design, allowing for a simpler and higher sealing rating, making it particularly suitable for use in high-humidity and dusty environments.

[0004] This electric valve has only a single sealing measure, relying solely on a sealing ring. Over long-term use, the sealing ring is prone to loosening. At the same time, gaps may appear between the sealing ring and the connecting pipe due to aging, affecting the sealing effect and making it difficult to effectively prevent water leakage at the interface. Water leakage not only wastes resources but may also damage the surrounding environment. The connection method of electric valves is usually relatively simple and cannot withstand large pressure and tension. Under high pressure, the connection is prone to loosening. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, the present invention provides an electric valve that can prevent water leakage at the interface, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electric valve that can prevent water leakage at the interface, including an electric valve body, a first connecting pipe provided at the bottom of the electric valve body, a fixing column fixedly connected to the top and bottom of the first connecting pipe, a fixing plate fixedly connected to the bottom of the fixing column, and a pressing connection mechanism provided at the top of the fixing plate;

[0007] The clamping connection mechanism includes a hydraulic rod, which is fixedly installed on the top of the fixed plate. A fixed block is fixedly connected to the top of the hydraulic rod. A motor is fixedly installed on one side of the fixed block. A fixed groove is opened inside the fixed block. A threaded rod is fixedly connected to the output end of the motor. A threaded sleeve is threadedly connected to the outside of the threaded rod. A connecting slide rod is fixedly connected to the bottom of the threaded sleeve. A movable locking block is fixedly connected to the bottom of the connecting slide rod.

[0008] A second connecting pipe is connected to one side of the first connecting pipe, and a fixing ring is fixedly sleeved on the outside of the second connecting pipe. A groove is opened on one side surface of the fixing ring, and a sealing mechanism is provided between the first connecting pipe and the second connecting pipe.

[0009] Preferably, the sealing mechanism includes a sealing ring, which is disposed on one side of a fixed ring. A positioning rod is fixedly connected to one side of the fixed ring. Positioning grooves are provided on one side of both the sealing ring and the first connecting pipe. The first connecting pipe and the sealing ring have the same diameter.

[0010] Preferably, the number of positioning rods and positioning slots is set to multiple, and the positioning rods and positioning slots are movably engaged.

[0011] Preferably, the outer surface of the second connecting pipe is provided with threads, the inner wall surface of the first connecting pipe is provided with threads, and the movable block is threadedly connected to the second connecting pipe.

[0012] Preferably, the fixing plate and the fixing column are slidably connected, and one end of the threaded rod passes through the fixing plate and extends into the fixing groove.

[0013] Preferably, the movable card block is movably engaged with the card slot, the bottom surface of the fixed block is provided with a through groove, and the connecting slide rod is slidably connected to the through groove.

[0014] Preferably, a sealing ring is fixedly connected to the inner wall of the first connecting pipe, and the sealing ring is disposed at one end of the second connecting pipe.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting up a clamping connection mechanism and a sealing mechanism, the motor drives the threaded rod to rotate, which in turn moves the threaded sleeve and the moving clamping block, so that the moving clamping block is threadedly connected to the second connecting pipe and movably engaged with the groove on the fixed ring. This connection method is firm and reliable, and can withstand greater pressure and tension, ensuring that the first and second connecting pipes are tightly connected together. This improves the clamping and clamping effect on the sealing ring, reduces problems such as leakage and pressure fluctuations caused by loose connections, and the good sealing performance can reduce the wear and corrosion of the connecting pipe interface by the fluid, extending the service life of the electric valve.

[0017] 2. The dual-seal design of the sealing ring and the sealing rubber ring significantly improves the sealing performance at the electric valve interface. The sealing rubber ring is squeezed between the first and second connecting pipes, playing a primary sealing role. The sealing ring further strengthens the sealing effect at the interface. The cooperation of multiple positioning rods and positioning grooves provides initial positioning of the sealing rubber ring, ensuring accurate installation. This guarantees that the sealing rubber ring is in the optimal sealing position between the connecting pipes, improving sealing reliability, effectively preventing water leakage at the interface, reducing resource waste and damage to the surrounding environment. The robust connection method reduces the probability of failure due to loose connections, further improving the reliability and service life of the electric valve. Attached Figure Description

A fixed block 6 is fixedly connected to the top of the hydraulic rod 5. A motor 7 is fixedly installed on one side of the fixed block 6. A fixed groove 8 is opened inside the fixed block 6. A threaded rod 9 is fixedly connected to the output end of the motor 7. A threaded sleeve 10 is threadedly connected to the outside of the threaded rod 9. A connecting slide rod 11 is fixedly connected to the bottom of the threaded sleeve 10. A movable locking block 12 is fixedly connected to the bottom of the connecting slide rod 11.

[0027] The first connecting pipe 2 is connected to the second connecting pipe 13 on one side. A fixing ring 14 is fixedly sleeved on the outside of the second connecting pipe 13. A groove 15 is opened on one side of the fixing ring 14. A sealing mechanism is provided between the first connecting pipe 2 and the second connecting pipe 13.

[0028] As attached Figure 3-5 As shown, the sealing mechanism includes a sealing ring 16, which is disposed on one side of a fixed ring 14. A positioning rod 17 is fixedly connected to one side of the fixed ring 14. Positioning grooves 18 are provided on one side of both the sealing ring 16 and the first connecting pipe 2. The first connecting pipe 2 and the sealing ring 16 have the same diameter. The number of positioning rods 17 and positioning grooves 18 is set to multiple. The positioning rods 17 and positioning grooves 18 are movably engaged, which can position the sealing ring 16 and prevent the sealing ring 16 from shifting and affecting the sealing performance.

[0029] As attached Figure 3-5 As shown, the outer surface of the second connecting pipe 13 is provided with threads, and the inner wall surface of the first connecting pipe 2 is provided with threads. The movable locking block 12 is threadedly connected to the second connecting pipe 13, and the connection between the first connecting pipe 2 and the second connecting pipe 13 is further improved by the stress between the threads.

[0030] As attached Figure 1 , 2 As shown in Figure 5, the fixed plate 4 and the fixed column 3 are slidably connected. One end of the threaded rod 9 passes through the fixed plate 4 and extends into the fixed groove 8. The movable block 12 is movably engaged with the groove 15. A through groove 20 is provided on the bottom surface of the fixed block 6. The connecting slide rod 11 is slidably connected with the through groove 20, which serves as a limit and facilitates the moving block 12 to be moved by the connecting slide rod 11.

[0031] As attached Figure 5As shown, a sealing ring 19 is fixedly connected to the inner wall of the first connecting pipe 2, and the sealing ring 19 is located at one end of the second connecting pipe 13, which further improves the sealing effect of the connection between the first connecting pipe 2 and the second connecting pipe 13 from the inside.

[0032] The working principle of this utility model is as follows: When it is necessary to connect the first connecting pipe 2 and the second connecting pipe 13, the hydraulic rod 5 is activated. The hydraulic rod 5 is fixedly installed on the top of the fixed plate 4, and a fixed block 6 is fixedly connected to the top of the hydraulic rod 5. The hydraulic rod 5 extends, pushing the fixed block 6 to move upward. A motor 7 is fixedly installed on one side of the fixed block 6. A fixed groove 8 is opened inside the fixed block 6. A threaded rod 9 is fixedly connected to the output end of the motor 7. When the motor 7 starts, it drives the threaded rod 9 to rotate. A threaded sleeve 10 is threadedly connected to the outside of the threaded rod 9. A connecting rod is fixedly connected to the bottom of the threaded sleeve 10. The slide rod 11 is connected to a movable locking block 12 at its bottom. When the threaded rod 9 rotates, the threaded sleeve 10 moves on the threaded rod 9, which drives the movable locking block 12 to move through the slide rod 11. The movable locking block 12 is threadedly connected to the second connecting pipe 13. At the same time, the movable locking block 12 is movably engaged with the locking groove 15 on the fixed ring 14. In this way, the first connecting pipe 2 and the second connecting pipe 13 are tightly connected together by the pressing connection mechanism, so that the sealing ring 16 is pressed between the first connecting pipe 2 and the second connecting pipe 13, thereby improving the sealing effect.

[0033] The sealing ring 16 is initially positioned by the cooperation of multiple positioning rods 17 and positioning grooves 18 to ensure that the sealing ring 16 is installed in an accurate position. The diameter of the first connecting pipe 2 and the sealing ring 16 is the same. When the first connecting pipe 2 and the second connecting pipe 13 are connected, the sealing ring 16 is squeezed between the two to play a sealing role and prevent water leakage at the interface. A sealing ring 19 is fixedly connected to the inner wall of the first connecting pipe 2. The sealing ring 19 is set at one end of the second connecting pipe 13. The sealing ring 19 further enhances the sealing effect at the interface and ensures that the electric valve will not leak during use.

[0034] This achieves a tight connection and good sealing between the first connecting pipe 2 and the second connecting pipe 13, effectively preventing water leakage at the interface.
