Specific embodiments

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0025] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] Embodiment 1: As Figure 1 - Figure 4As shown in the figure, the utility model provides a dust-proof and silent solenoid valve, which includes a solenoid valve body 4. A protection mechanism 3 is installed outside the solenoid valve body 4, and a dust-proof mechanism 2 is installed on one side of the protection mechanism 3. The dust-proof mechanism 2 includes an outer cylinder body 21. One end of the outer cylinder body 21 is lapped with a dust-proof net 22. One side of the dust-proof net 22 abuts against an abutting block 28. One end of the abutting block 28 is fixedly connected with a second rotating rod 27. One end of the second rotating rod 27 is rotatably connected with a positioning block 29. One end of the positioning block 29 is fixedly connected with the outer surface of the outer cylinder body 21. The other end of the second rotating rod 27 is rotatably connected with a first rotating rod 26. One end of the first rotating rod 26 is rotatably connected with a sliding block 25. Threads are provided on the outside of the outer cylinder body 21, and a socket plate 23 is threadedly connected to the threaded end of the outer cylinder body 21. An annular chute 24 is provided on one side of the socket plate 23, and the outside of the sliding block 25 is slidably connected to the inside of the annular chute 24.

[0027] Through the threaded part provided on the outside of the outer cylinder body 21, the socket plate 23 is threadedly connected to the threaded part on the outside of the outer cylinder body 21. When the socket plate 23 is rotated, the socket plate 23 moves outside the outer cylinder body 21. At the same time, during the rotation of the socket plate 23, the sliding block 25 slides inside the annular chute 24, so that the sliding block 25 only moves in the vertical direction. The movement of the sliding block 25 drives the first rotating rod 26 to rotate, and the second rotating rod 27 rotates. One end of the second rotating rod 27 rotates at the positioning block 29, thereby driving the abutting block 28 to move. By moving the top end of the abutting block 28 to abut against the dust-proof net 22, the dust-proof net 22 can be fixed. When the top end of the abutting block 28 moves away from the dust-proof net 22, the dust-proof net 22 can be removed from the outside of the outer cylinder body 21 for cleaning. Through the setting of the dust-proof net 22, dust can be prevented from falling into the inside of the outer cylinder body 21 and affecting the solenoid valve body 4, isolating the solenoid valve body 4 from external dust, protecting the solenoid valve body 4, and preventing dust from invading the inside of the solenoid valve body 4 and affecting its service life.

[0028] Example 2: As Figure 1 、 Figure 2 and Figure 4As shown in the figure, the protection mechanism 3 includes a first housing 31 and a second housing 35. One side of the second housing 35 is fixedly connected with a rubber pad 313, and one end of the rubber pad 313 is lapped with one end of the first housing 31; a second fixing block 38 is fixedly connected to the outside of the first housing 31, and a second slot 312 is opened on one side of the second fixing block 38; a first fixing block 36 is fixedly connected to the outside of the second housing 35, and a mounting block 39 abuts against one side of the first fixing block 36. One end of the mounting block 39 is fixedly connected with a connecting rod 314, and one end of the connecting rod 314 is fixedly connected with a connecting block 311; a first slot 37 is opened on one side of the first fixing block 36; a second spring 310 is sleeved outside the connecting rod 314, and both ends of the second spring 310 are respectively arranged on one side of the connecting block 311 and one side of the second fixing block 38; telescopic rods 34 are fixedly connected to the inner sides of both the first housing 31 and the second housing 35, and a sound insulation collar 32 is fixedly connected to one end of each telescopic rod 34; a first spring 33 is sleeved outside each telescopic rod 34. The first spring 33 is divided into two groups. One group of the first springs 33 has its two ends respectively arranged between the sound insulation collar 32 and the first housing 31, and the other group of the first springs 33 has its two ends respectively arranged between the sound insulation collar 32 and the second housing 35; both ends of the solenoid valve body 4 are fixedly communicated with a pipeline 1, and one end of each of the two pipelines 1 passes through the connection part of the second housing 35 and the first housing 31.

[0029] By opening the second slot 312 on the second fixing block 38, opening the first slot 37 on the first fixing block 36, and setting the first slot 37 perpendicular to the second fixing block 38, when the second spring 310 is in the initial state, the direction of the mounting block 39 is the same as that of the second slot 312. At this time, the mounting block 39 abuts against one side of the first fixing block 36 to fix the first housing 31 and the second housing 35, so that the first housing 31 and the second housing 35 are installed outside the solenoid valve body 4 to protect the solenoid valve body 4. By rotating the connecting block 311 to drive the direction of the mounting block 39 to move to be the same as that of the first slot 37, the mounting block 39 can be taken out of the first slot 37 outward, separating the first housing 31 from the second housing 35 to process the internal solenoid valve body 4. When the first housing 31 and the second housing 35 are fixed, sound insulation collars 32 are attached to both sides of the pipeline 1. At the same time, the setting of the first spring 33 and the telescopic rod 34 can push the sound insulation collar 32 to closely fit with the outer surface of the pipeline 1. When a fluid flows through the pipeline 1, the setting of the sound insulation collar 32 can reduce the volume of the fluid flowing through and reduce the noise impact.

[0030] Usage method and working principle of this device: Fix the first housing 31 and the second housing 35 by making the mounting block 39 abut against one side of the first fixing block 36, install the first housing 31 and the second housing 35 outside the solenoid valve body 4 to protect the solenoid valve body 4. Rotate the connecting block 311 by 90 degrees to drive the mounting block 39 to move to the same direction as the first slot 37, and then the mounting block 39 can be taken out of the first slot 37 outward to separate the first housing 31 from the second housing 35. When the first housing 31 and the second housing 35 are fixed, sound insulation collar 32 is attached to both sides of the pipe 1. The setting of the sound insulation collar 32 can reduce the sound volume of the flowing fluid. When rotating the socket plate 23, the socket plate 23 moves outside the outer cylinder 21, and the sliding block 25 moves to drive the first rotating rod 26 to rotate, and the second rotating rod 27 rotates. One end of the second rotating rod 27 rotates at the positioning block 29, thereby driving the abutting block 28 to move. When the top end of the abutting block 28 moves to abut against the dust-proof net 22, the dust-proof net 22 can be fixed. When the top end of the abutting block 28 moves away from the dust-proof net 22, the dust-proof net 22 can be removed from the outside of the outer cylinder 21 for cleaning. The setting of the dust-proof net 22 can prevent dust from falling into the inside of the outer cylinder 21 and affecting the solenoid valve body 4.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
