Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulse solenoid valve technology, specifically a high-pressure stable pulse solenoid valve. Background Technology
[0002] High-pressure stable pulse solenoid valves are solenoid valves used in high-pressure environments that can generate stable pulse signals to control the flow of fluids or gases. They are a type of pulse solenoid valve. A pulse solenoid valve is a special type of solenoid valve used to control the flow of fluids or gases. It generates pulse signals by rapidly switching an electromagnetic relay, causing the valve to open or close quickly, thereby achieving precise control of fluids or gases.
[0003] Existing pulse solenoid valves, such as the one disclosed in publication number CN217463401 U, have advantages such as compact structure, easy assembly, ability to meet the needs of use in small spaces, and good adaptability and versatility. However, when connecting the water inlet on one side of this pulse solenoid valve to the external pipeline, it is generally connected by a thread. After the threaded connection, it is inconvenient to add a sealing structure on the inner and outer sides of the connection, which makes it difficult to improve its sealing performance. Therefore, we propose a high-pressure stable pulse solenoid valve. Utility Model Content
[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the technical solution adopted by this utility model is as follows:
[0006] A high-pressure stable pulse solenoid valve includes: a solenoid valve body, an inner sealing assembly, and an outer sealing assembly; the solenoid valve body includes an inlet pipe and an outlet pipe respectively disposed on its side and bottom; the inner sealing assembly includes an inner sealing ring fixedly installed at the inner end of the inlet pipe, an inner sealing gasket movably installed on the outer side of the inner sealing ring, an inner mounting port opened in the inlet pipe, an inner sealing ring movably installed in the inner mounting port, and a connecting pipe threadedly installed in the inlet pipe; the outer sealing assembly includes an outer sealing port opened on the outer side of the inlet pipe, an outer sealing gasket movably installed in the outer sealing port, a second cavity disposed in the outer sealing gasket, and a compression sleeve movably installed in the outer sealing port.
[0007] Preferably, the inner sealing gasket also has a first cavity.
[0008] Preferably, a groove is provided on one side of the inner sealing ring, and the groove has a circular structure.
[0009] Preferably, a raised ring is also fixedly provided on one side of the inner sealing gasket, and the raised ring and the groove are matched.
[0010] Preferably, a nut is also fixedly installed on the outer end of the clamping sleeve.
[0011] Preferably, the outer end of the air intake pipe is provided with an external thread, and the external thread is matched and connected with the nut.
[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0013] 1. In this utility model, after the connecting pipe is connected to the inner end of the intake pipe, the connecting pipe will press the inner sealing gasket between the inner sealing ring and the inner sealing gasket during rotation. When the inner sealing gasket is pressed, the first cavity inside it is pressed, so that the inner sealing gasket expands on both sides during the pressing. This causes the outer side to expand and press the outer end of the inner sealing ring, the inner end of the inner sealing gasket to fit tightly into the groove, and the outer end of the inner sealing gasket to fit tightly into the front end of the connecting pipe, thereby improving the sealing effect between the intake pipe and the connecting pipe.
[0014] 2. In this utility model, the outer sealing gasket installed inside the outer sealing port on the outside of the air intake pipe and the connecting pipe will also press the second cavity inside it during the pressing of the compression sleeve, so that the inner and outer sides of the outer sealing gasket expand tightly against the outer wall of the connecting pipe and the inner wall of the outer sealing port during the pressing, thereby improving the sealing effect between the outside of the air intake pipe and the connecting pipe.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-pressure stable pulse solenoid valve.
[0025] Example 1:
[0026] Combination Figure 1-4 As shown, this utility model provides a high-pressure stable pulse solenoid valve, comprising: a solenoid valve body 100, an inner sealing assembly 200, and an outer sealing assembly 300; the solenoid valve body 100 includes an inlet pipe 101 and an outlet pipe 102 respectively disposed on its side and bottom; the inner sealing assembly 200 includes an inner sealing ring 201 fixedly installed at the inner end of the inlet pipe 101, an inner sealing gasket 202 movably installed on the outer side of the inner sealing ring 201, an inner mounting port 203 opened in the inlet pipe 101, an inner sealing ring 204 movably installed in the inner mounting port 203, and a connecting pipe 205 threadedly connected to the inlet pipe 101; the outer sealing assembly 300 includes an inlet pipe 101 with an inner sealing ring 204 movably installed in the inner mounting port 203, and a connecting pipe 205 threadedly connected to the inlet pipe 101; the outer sealing assembly 300 includes an inner sealing ring 201 fixedly installed on the outer side of the inlet pipe 101. The system includes an outer sealing port 301, an outer sealing gasket 302 movably installed inside the outer sealing port 301, a second cavity 303 provided in the outer sealing gasket 302, and a clamping sleeve 304 movably installed inside the outer sealing port 301. The inner sealing gasket 202 also has a first cavity 206. A groove 207 is provided on one side of the inner sealing ring 201, and the groove 207 has a circular structure. A convex ring 208 is fixedly provided on one side of the inner sealing gasket 202, and the convex ring 208 matches the groove 207. A nut 305 is fixedly installed on the outer end of the clamping sleeve 304. An external thread 306 is provided on one side of the outer end of the air intake pipe 101, and the external thread 306 matches the nut 305.
[0027] Specifically, the high-pressure stable pulse solenoid valve is a solenoid valve used in high-pressure environments to generate stable pulse signals to control the flow of fluids or gases, and belongs to a type of pulse solenoid valve. After the inner end of the inlet pipe 101 on the solenoid valve body 100 is connected to the connecting pipe 205, the connecting pipe 205 will press the inner sealing gasket 202 between the inner sealing ring 201 and the inner sealing gasket 202 during rotation. When the inner sealing gasket 202 is pressed, the first cavity 206 within it is compressed, causing the inner sealing gasket 202 to expand on both sides during compression. This expansion presses the outer end of the inner sealing ring 204, the inner end of the inner sealing gasket 202's convex ring 208 tightly against the groove 207, and the outer end of the inner sealing gasket 202 tightly against the front end of the connecting pipe 205, thereby improving the sealing between the inlet pipe 101 and the connecting pipe 205. To improve the sealing effect, the outer sealing gasket 302 installed inside the outer sealing port 301 on the outside of the intake pipe 101 and the connecting pipe 205 will also be pressed by the clamping sleeve 304 to compress the second cavity 303 inside it. This will cause the outer sealing gasket 302 to expand and tightly adhere to the outer wall of the connecting pipe 205 and the inner wall of the outer sealing port 301 during the compression, thereby improving the sealing effect between the outer side of the intake pipe 101 and the connecting pipe 205. In turn, the double-layer sealing structure between the inner and outer sides of the intake pipe 101 and the connecting pipe 205 will enhance the sealing performance of the connecting pipe 205 after installation. The nut 305 fixedly installed on the outer end of the clamping sleeve 304 and the external thread 306 provided on the outer side of the intake pipe 101 are mainly used for the installation of the nut 305, so that the clamping sleeve 304 can be driven by the nut 305 to compress the outer sealing gasket 302.
[0028] Working principle and usage process of this utility model:
[0029] When the connecting pipe 205 is installed in the intake pipe 101 on the solenoid valve body 100, the connecting pipe 205 will rotate into the intake pipe 101 and, during rotation, press the inner sealing gasket 202 at the outer end of the inner sealing ring 201 to compress the first cavity 206 within the inner sealing gasket 202. This causes the inner sealing gasket 202 to expand outward on both sides. The outer side of the expanded inner sealing gasket 202 will tightly adhere to the outer inner sealing ring 204, the convex ring 208 at the inner end of the inner sealing gasket 202 will tightly adhere to the groove 207, and the outer end of the inner sealing gasket 202 will tightly adhere to the front end of the connecting pipe 205, thereby strengthening the intake... The sealing performance between the air pipe 101 and the connecting pipe 205 is improved by tightening the nut 305 at the outer end of the air inlet pipe 101. The compression sleeve 304, which is tightened simultaneously with the nut 305, is then tightened to compress the outer sealing gasket 302 inside the outer sealing port 301. This causes the outer sealing gasket 302 to expand on both sides during compression, so that the expanded parts on both sides are tightly attached to the outer wall of the connecting pipe 205 and the inner wall of the outer sealing port 301. This ensures the seal between the outer side of the air inlet pipe 101 and the connecting pipe 205. Furthermore, the double-layer seal on the inner and outer sides of the connecting pipe 205 after installation enhances its sealing performance.
