Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic valve technology, specifically relating to an anti-disengagement two-position two-way electromagnetic valve. Background Technology

[0002] A 2-position 2-way solenoid valve is an industrial valve that controls the flow of fluid using electromagnetic force. The "2-position" in its name indicates that the valve has only two operating states (open / closed), while "2-way" means that the valve has only two fluid interfaces (inlet and outlet). Its core function is to act as a "switch" in automation systems, precisely controlling the flow path of liquids or gases, and it is widely used in scenarios requiring rapid response and reliable on / off switching.

[0003] During installation and use, existing 2-position 2-way solenoid valves typically require the connecting wire to be threaded through the conduit in the protective cover and then connected to the solenoid valve's terminal block to achieve power control. However, in actual operation, due to the lack of an effective anti-detachment mechanism for the connecting wire, it is highly susceptible to loosening or even falling off the terminal block when the equipment is subjected to external mechanical vibration or tension caused by improper operation. This connection failure directly leads to a power outage for the solenoid valve, severely affecting its normal opening and closing function and the stable operation of the entire system. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-detachment two-position two-way solenoid valve, which aims to solve the problem that the connecting wire lacks an effective anti-detachment mechanism. When the equipment is subjected to external mechanical vibration or tension caused by improper human operation, the connecting wire is very easy to loosen or even fall off the terminal block. This connection failure will directly lead to the problem of power interruption of the solenoid valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a two-position two-way solenoid valve with anti-detachment capability, comprising a solenoid valve assembly, the solenoid valve assembly comprising a valve body, a terminal block, a protective cover, and a wiring conduit, the terminal block being inserted into the side surface of the valve body, the surface of the terminal block being fitted with a protective cover of a suitable size for protection, the wiring conduit being connected through the side surface of the protective cover, the end of the wiring conduit being fitted with an anti-detachment component for preventing the wiring from falling off, and a sealing component being provided between the protective cover and the valve body.

[0006] As a preferred embodiment of the present invention, the anti-disengagement two-position two-way solenoid valve includes a convex thread, a groove, a pipe plug, an end plate, a limiting ring, a rotating ring, and an internal threaded tube. The convex thread is connected to the outer surface of the connecting pipe, and the surface of the convex thread is fitted with the internal threaded tube.

[0007] As a preferred embodiment of the present invention, a two-position two-way solenoid valve with anti-detachment feature is provided, wherein a plug made of rubber and adapted to the inner wall size is inserted into the wiring tube, an end plate is connected to the end of the plug, a limit ring is connected to the side surface of the end plate, and a rotating ring connected to the internal spiral tube is sleeved on the surface of the limit ring.

[0008] As a type of anti-detachment two-position two-way solenoid valve of this utility model, preferably, the side surface of the wiring pipe and the protruding thread is provided with a groove for setting the wiring.

[0009] As a preferred embodiment of the present invention, a two-position two-way solenoid valve with anti-detachment feature, the sealing assembly includes a first sealing ring, a second sealing ring, a connecting threaded tube, a round hole, a sealing bearing, and a fastening screw. The connecting threaded tube is connected to the side surface of the valve body, and a round hole adapted to the connecting threaded tube is opened in the middle of the terminal block. A sealing bearing is fitted onto the side surface of the protective cover, and a fastening screw that is threadedly connected to the connecting threaded tube is connected inside the sealing bearing.

[0010] As a type of anti-detachment two-position two-way solenoid valve according to this utility model, preferably, the side surface of the terminal block is connected to a first sealing ring, and the side surface of the protective cover is connected to a second sealing ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model provides a two-position two-way solenoid valve with anti-detachment function. The connecting wire passing through the connecting pipe is inserted into the wire groove. Then, the end plate drives the inner screw tube to move to the end of the convex thread through the limiting ring and the rotating ring. When the inner screw tube rotates on the surface of the convex thread, it can drive the end plate to move axially through the rotating ring and the limiting ring. The axial movement of the end plate can drive the pipe plug to move axially into the connecting pipe. When the pipe plug moves to the farthest end, it can squeeze the connecting wire. At this time, the squeezing of the connecting wire by the pipe plug can play an anti-detachment role, thereby preventing the connecting wire from falling off due to the pulling force.

[0013] This utility model provides a two-position two-way solenoid valve with anti-detachment capability. When the fastening screw rotates, it can move axially into the inner part of the connecting screw tube through the threaded connection. When the fastening screw moves axially, it can drive the protective cover to move axially through the sealed bearing. The axial movement of the protective cover can squeeze the terminal block through the second sealing ring. When the terminal block is subjected to force, it can press the first sealing ring onto the side surface of the valve body. In this way, the first sealing ring can seal between the valve body and the terminal block, and the second sealing ring can seal between the terminal block and the protective cover, thereby achieving a sealed connection to protect the terminal block.

[0025] Preferably, a rubber plug 203 that is adapted to the inner wall size of the conduit 104 is inserted inside the conduit 104. An end plate 204 is connected to the end of the conduit 203. A limit ring 205 is connected to the side surface of the end plate 204. A rotating ring 206 that is connected to the inner threaded tube 207 is sleeved on the surface of the limit ring 205.

[0026] In practical use, when the internal threaded tube 207 rotates, it can move axially on the surface of the convex thread 201. When the internal threaded tube 207 moves axially, it can pull the end plate 204 axially through the rotating ring 206 and the limiting ring 205. The axial movement of the end plate 204 can drive the pipe plug 203 to move into the wiring tube 104.

[0027] Preferably, the side surfaces of the conduit 104 and the threaded 201 are provided with grooves 202 for wiring;

[0028] In practical use, after the connecting wire passes through the inside of the connecting pipe 104 of the protective cover 103, it can be inserted into the inside of the wire groove 202, so that the connecting wire can be squeezed by inserting the pipe plug 203 into the inside of the connecting pipe 104.

[0029] Preferably, the sealing assembly 3 includes a first sealing ring 301, a second sealing ring 302, a connecting threaded tube 303, a round hole 304, a sealing bearing 305, and a fastening screw 306.

When the fastening screw 306 moves axially, it can drive the protective cover 103 to move axially through the sealing bearing 305. The axial movement of the protective cover 103 can squeeze the terminal block 102 through the second sealing ring 302. When the terminal block 102 is subjected to force, it can press the first sealing ring 301 onto the side surface of the valve body 101. In this way, the first sealing ring 301 can seal between the valve body 101 and the terminal block 102, and the second sealing ring 302 can seal between the terminal block 102 and the protective cover 103, thereby achieving a sealed connection to protect the terminal block 102.

[0034] Next, the connector wire is inserted into the wire groove 202. Then, the end plate 204 drives the tube plug 203 to be inserted into the connector tube 104. When the end plate 204 drives the internal thread tube 207 to the end of the convex thread 201 through the limiting ring 205 and the rotating ring 206, the internal thread tube 207 can be rotated.
