Description

Technical Field

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

[0002] An electric valve is an automated fluid control device that controls the opening and closing of valves and regulates flow through an electric actuator. It is widely used in industrial pipeline systems. Its core function is to use electrical energy to drive the valve to achieve precise control over the flow rate, pressure, or direction of liquid, gas, or air systems.

[0003] In existing technology, electric valves consist of two parts: an electric actuator and a valve body. Electrical energy drives the actuator to open, close, or adjust the valve opening. The valve body comprises a valve body, valve cover, valve groove, valve plate, and valve stem. The valve cover is mounted on the valve body via screw holes. A valve groove is formed on the valve body, and the valve plate is movably connected to it. The bottom end of the valve stem is fixed to the valve plate, and the top end is connected to the electric actuator. The electric actuator moves the valve stem upwards, causing the valve plate to move upwards, opening the valve and allowing fluid to flow through the valve body. Conversely, the electric actuator moves the valve stem downwards, causing the valve plate to move downwards, closing the valve and blocking fluid flow from the valve body. After prolonged use, the valve body accumulates a large amount of impurities from the fluid. This requires removing the screws from the screw holes and then removing the valve cover from the valve body. This allows the valve stem and valve plate to be removed from the valve groove, facilitating disassembly and cleaning of the valve plate.

[0004] In addition, in the existing technology, when installing the valve cover and valve body, it is usually necessary to put a gasket on the screw and then apply a very large preload to the screw, so that the gasket is compressed to a large extent. The elasticity of the gasket is used to apply a reaction force to the screw, thereby generating a large frictional force between the screw and the screw hole, so as to achieve the anti-loosening effect.

[0005] However, according to the existing screw anti-loosening methods, the valve plate needs to be disassembled and cleaned regularly. The disassembly, cleaning and reassembly of the valve plate requires the disassembly and assembly of the valve cover. The disassembly and assembly of the valve cover requires the disassembly and assembly of screws and screw holes. Excessive friction causes excessive wear on the threaded connection between the screw and the screw hole during disassembly and assembly, which in turn greatly shortens the service life of the screw. Utility Model Content

[0006] The purpose of this invention is to provide a detachable and cleanable electric valve to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a detachable and cleanable electric valve, comprising: a valve body and a valve cover, wherein a screw hole is formed on the surface of the valve body, and a through hole is formed on the surface of the valve cover, wherein a screw is movably inserted into the through hole, the screw is installed in the screw hole by a threaded connection, a washer is fitted on the screw shank, and an anti-loosening plate mounting groove is formed on the surface of the valve cover, wherein an anti-loosening plate is movably inserted into the anti-loosening plate mounting groove, and a nut groove is formed at the bottom end of the anti-loosening plate, wherein the nut of the screw is movably inserted into the nut groove.

[0008] Preferably, the screw nut has a hexagonal prism structure, the nut groove mates with the screw nut, the anti-loosening plate has a rectangular block structure, and the anti-loosening plate mounting groove mates with the anti-loosening plate.

[0009] Preferably, the surface of the anti-loosening plate is provided with a retaining groove, and the surface of the valve cover is provided with a retaining groove.

[0010] Preferably, one end of the card plate is rotatably connected to the top of the inner wall of the slot, and the other end of the card plate is fixed with a card block. The card block is movably inserted into the slot, and the bottom end of the card block is provided with an inclined surface.

[0011] Preferably, a spring is fixed to the inner wall of the slot of the card plate, and the other end of the spring is fixed to the surface of the card plate.

[0012] Preferably, a tie rod is fixed to the surface of the anti-loosening plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The detachable and cleanable electric valve proposed in this utility model uses a washer fitted onto a screw, and then the screw is installed in the screw hole along the through hole, thereby realizing the installation between the valve body and the valve cover. When tightening the screw, it is not necessary to apply too much pre-tightening force to the screw. Just slightly tighten the screw so that the screw nut is aligned with the nut groove at the bottom of the anti-loosening plate. Then, insert the anti-loosening plate into the anti-loosening plate mounting groove, and let the screw nut be inserted into the nut groove. The anti-loosening plate mounting groove provides circumferential restraint to the anti-loosening plate, and the anti-loosening plate in turn provides circumferential restraint to the screw, thus realizing the anti-loosening of the screw. In this way, the screw is prevented from loosening. When the screw is disassembled and assembled, the threaded connection between the screw and the screw hole will not bear too much friction, which will extend the service life of the screw.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a detachable and cleanable electric valve, comprising: a valve body 1 and a valve cover 2. A screw hole 3 is provided on the surface of the valve body 1, and a through hole 4 is provided on the surface of the valve cover 2. A screw 5 is movably inserted into the through hole 4. The screw 5 is installed in the screw hole 3 by a threaded connection. A washer 14 is sleeved on the screw shank of the screw 5. An anti-loosening plate mounting groove 6 is provided on the surface of the valve cover 2. An anti-loosening plate 7 is movably inserted into the anti-loosening plate mounting groove 6. A nut groove 8 is provided at the bottom end of the anti-loosening plate 7. The nut of the screw 5 is movably inserted into the nut groove 8. The nut of the screw 5 has a hexagonal prism structure. The nut groove 8 cooperates with the nut of the screw 5. The anti-loosening plate 7 has a rectangular block structure. The anti-loosening plate mounting groove 6 cooperates with the anti-loosening plate 7.

[0024] In actual use, a washer 14 is placed on the screw 5, and then the screw 5 is installed in the screw hole 3 along the through hole 4, thereby realizing the installation between the valve body 1 and the valve cover 2. When tightening the screw 5, it is not necessary to apply too much pre-tightening force to the screw 5. Just slightly tighten the screw 5 so that the nut of the screw 5 is aligned with the nut groove 8 at the bottom of the anti-loosening plate 7. Then insert the anti-loosening plate 7 into the anti-loosening plate mounting groove 6, and insert the nut of the screw 5 into the nut groove 8. The anti-loosening plate mounting groove 6 provides circumferential restraint to the anti-loosening plate 7, and the anti-loosening plate 7 provides circumferential restraint to the screw 5, thus realizing the anti-loosening of the screw 5. By preventing the screw 5 from loosening in this way, when the screw 5 is disassembled and assembled, the threaded connection between the screw 5 and the screw hole 3 will not bear too much friction, which helps to extend the service life of the screw 5.

[0025] Example 2: Based on Example 1, in order to achieve the limiting and releasing of the anti-loosening plate 7, a retaining plate groove 9 is opened on the surface of the anti-loosening plate 7, and a retaining groove 10 is opened on the surface of the valve cover 2. One end of the retaining plate 11 is rotatably connected to the top of the inner wall of the retaining plate groove 9, and a retaining block 12 is fixed to the other end of the retaining plate 11. The retaining block 12 is movably inserted into the retaining groove 10. A slope is provided at the bottom end of the retaining block 12. A spring 13 is fixed on the inner wall of the retaining plate groove 9, and the other end of the spring 13 is fixed on the surface of the retaining plate 11. A pull rod 15 is fixed on the surface of the anti-loosening plate 7.

[0026] When the anti-loosening plate 7 is installed into the anti-loosening plate mounting groove 6, under the action of the inclined surface of the locking block 12, the locking block 12 retracts into the locking plate mounting groove 9, and the locking plate 11 rotates into the locking plate mounting groove 9. The spring 13 is compressed. When the anti-loosening plate 7 is fully inserted into the anti-loosening plate mounting groove 6, the locking block 12 is aligned with the locking groove 10. Under its own elasticity, the spring 13 pushes the locking plate 11 back to its original position, allowing the locking block 12 to be inserted into the locking groove 10, thereby limiting the anti-loosening plate 7 in the anti-loosening plate mounting groove 6. When it is necessary to remove the screw 5, insert your fingernail into the locking groove 10 and push the locking block 12 out of the locking groove 10, thereby releasing the limitation of the anti-loosening plate 7. Then, pinch the pull rod 15 and pull upward to remove the anti-loosening plate 7 from the anti-loosening plate mounting groove 6.

[0027] In actual use, a washer 14 is fitted onto screw 5, and then screw 5 is installed in screw hole 3 along through hole 4, thus achieving the installation between valve body 1 and valve cover 2. When tightening screw 5, it is not necessary to apply too much pre-tightening force to screw 5; just slightly tighten screw 5 so that the nut of screw 5 is aligned with the nut groove 8 at the bottom of anti-loosening plate 7. Then, insert anti-loosening plate 7 into anti-loosening plate mounting groove 6, and insert the nut of screw 5 into nut groove 8. Anti-loosening plate mounting groove 6 provides circumferential restraint to anti-loosening plate 7, and anti-loosening plate 7 in turn provides circumferential restraint to screw 5, thereby achieving anti-loosening of screw 5. By preventing screw 5 from loosening in this way, the threaded connection between screw 5 and screw hole 3 will not bear too much friction when screw 5 is disassembled and assembled, which extends the life of screw 5. The anti-loosening plate 7 serves to extend its service life. When the anti-loosening plate 7 is installed into the anti-loosening plate mounting groove 6, under the action of the inclined surface of the locking block 12, the locking block 12 retracts into the locking plate mounting groove 9, and the locking plate 11 rotates inward into the locking plate mounting groove 9. The spring 13 is compressed. When the anti-loosening plate 7 is fully inserted into the anti-loosening plate mounting groove 6, the locking block 12 aligns with the locking groove 10. Under its own elasticity, the spring 13 pushes the locking plate 11 back to its original position, allowing the locking block 12 to be inserted into the locking groove 10, thereby limiting the anti-loosening plate 7 in the anti-loosening plate mounting groove 6. When it is necessary to remove the screw 5, insert your fingernail into the locking groove 10 and push the locking block 12 out of the locking groove 10, thereby releasing the limitation of the anti-loosening plate 7. Then, pinch the pull rod 15 and pull upward to remove the anti-loosening plate 7 from the anti-loosening plate mounting groove 6.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
