Description

Technical Field

[0001] This utility model relates to a detachable and cleanable electric valve, belonging to the field of electric valve technology. Background Technology

[0002] Simply put, an electric valve is a valve controlled by an electric actuator to open and close the valve. It can be divided into two parts: the upper part is the electric actuator and the lower part is the valve. Electric valves are high-end products among automatic control valves. They can not only realize the on / off function, but also the regulating electric valve can realize the valve position adjustment function.

[0003] Chinese patent CN219510161U proposes a detachable and cleanable electric valve. Although the valve plate can be cleaned and disassembled by setting an annular fixing plate, an integrated extension ring, and a hand-tightening screw, the installation and disassembly of this design is still not convenient enough, and the sealing performance is poor, resulting in low practicality. There is an urgent need for a detachable and cleanable electric valve to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a detachable and cleanable electric valve to solve the problems mentioned in the background. This utility model has a reasonable structure, good sealing performance, and facilitates the installation and disassembly of the ball valve, thereby facilitating the cleaning of the valve body and the ball valve itself. It is simple to operate and highly practical.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a detachable and cleanable electric valve, comprising a valve body, a drive motor, a ball valve, a sealing mounting seat, a positioning column, a positioning sleeve, a top seat, a limit seat, and a rotating seat. The drive motor is mounted on the top of the valve body, a ball valve is disposed inside the valve body, a sealing mounting seat is disposed on the lower end face of the valve body, a positioning column is disposed on the outer side of the sealing mounting seat, a positioning sleeve is welded to the outer side of the valve body, a top seat is disposed above the outer side of the valve body, a limit seat is embedded inside the top seat, and a rotating seat is rotatably disposed inside the limit seat.

[0006] Furthermore, the valve body has an internal cavity, the ball valve is disposed inside the cavity, a sealing mounting groove is provided at the lower end of the valve body, the sealing mounting seat engages with the sealing mounting groove, and a sealing ring is adhered to the inner side of the sealing mounting seat.

[0007] Furthermore, a hexagonal motor shaft is provided inside the cavity, and the output end of the drive motor is engaged with the hexagonal motor shaft. A hexagonal groove is provided on the top of the ball valve, and the hexagonal motor shaft is engaged with the ball valve through the hexagonal groove.

[0008] Furthermore, the ball valve has a slot at the bottom, a rotating block is provided inside the slot, and a connecting block is provided on the upper surface of the sealing mounting seat. The connecting block engages with the slot, and a rotating groove is provided inside the connecting block. The rotating block matches the rotating groove.

[0009] Furthermore, the ball valve has through slots at both ends, the direction of which is consistent with the direction of the rotating block. The positioning pin and the positioning sleeve are matched and engaged with each other. The lower end face of the rotating seat is provided with a threaded rod, and the upper end face of the positioning pin is provided with a threaded groove. The threaded rod and the threaded groove are engaged with each other.

[0010] Furthermore, the position of the rotating seat corresponds one-to-one with the positioning sleeve, the rotating seat rotates and engages along the inner wall of the limiting seat, and a butterfly-shaped hand tightening head is provided on the upper end face of the rotating seat.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a detachable and cleanable electric valve. Because it adds a butterfly hand tightening head, a rotating seat, a threaded rod, a positioning rod, and a positioning sleeve, when it is necessary to disassemble the valve body and ball valve for cleaning, the user first rotates the butterfly hand tightening head in the opposite direction, thereby driving the rotating seat to rotate. The rotating seat can drive the threaded rod to rotate coaxially. Since the threaded rod and the thread groove are engaged with each other, the rotation of the threaded rod causes it to continuously disengage from the positioning pin, making it easy for the user to remove the positioning pin from the positioning sleeve. This allows the sealing mounting seat to be removed from the sealing mounting groove, and then the ball valve can be removed from the cavity through the sealing mounting groove.

The drive motor 2 is installed on the top of the valve body 1, the ball valve 3 is installed inside the valve body 1, the sealing mounting seat 4 is installed on the lower end face of the valve body 1, the positioning column 5 is installed on the outer side of the sealing mounting seat 4, the positioning sleeve 6 is welded to the outer side of the valve body 1, the top seat 7 is installed above the outer side of the valve body 1, the limit seat 8 is embedded inside the top seat 7, and the rotating seat 9 is rotatably installed inside the limit seat 8. This design solves the problem that the original detachable and cleanable electric valve is not convenient to install and disassemble.

[0023] As the first embodiment of this utility model: A cavity 11 is provided inside the valve body 1, and a ball valve 3 is disposed inside the cavity 11. The ball valve 3 can rotate inside the cavity 11. A sealing mounting groove 13 is provided at the lower end of the valve body 1. A sealing mounting seat 4 is engaged with the sealing mounting groove 13. A sealing ring 43 is bonded to the inner side of the sealing mounting seat 4. The sealing ring 43 can improve the sealing performance between the sealing mounting groove 13 and the sealing mounting seat 4. A hexagonal motor shaft 21 is provided inside the cavity 11. The output end of the drive motor 2 is engaged with the hexagonal motor shaft 21. The drive motor 2 shaft can drive the hexagonal motor shaft 21 to rotate. A hexagonal groove 32 is provided at the top of the ball valve 3. The hexagonal motor shaft 21 is engaged with the ball valve 3 through the hexagonal groove 32. The hexagonal motor shaft 21 can drive the ball valve 3 to rotate through the hexagonal groove 32.

[0024] The ball valve 3 has a hollow groove 33 at its bottom, and a rotating block 34 is installed inside the hollow groove 33. A connecting block 41 is installed on the upper surface of the sealing mounting seat 4. The connecting block 41 engages with the hollow groove 33 and can rotate relative to the inner wall of the hollow groove 33. A rotating groove 42 is provided inside the connecting block 41, and the rotating block 34 matches the rotating groove 42. The rotating block 34 can rotate relative to the inner wall of the rotating groove 42. The design of the rotating groove 42 allows the rotating block 34 to rotate only 90°, which facilitates the adjustment of the angle of the ball valve 3. Through grooves 31 are provided at both ends of the ball valve 3. The positioning pin 5 and the positioning sleeve 6 are aligned with the direction of the rotating block 34 and are engaged with each other.
