[0025] First, place the pilot head body 2 inside the placement groove 3, and then put the first sound insulation cover 4 and the second sound insulation cover 5 on the surface of the solenoid valve body 1. Then, the sound insulation pad 6 inside the first sound insulation cover 4 and the second sound insulation cover 5 will contact the solenoid valve body 1, thereby reducing the noise of the solenoid valve body 1 during operation.

[0026] refer to Figures 1 to 5 The limiting assembly 8 includes two groups of plug-ins 801. The front side of the plug-in block 801 is fixedly installed on the back side of the second sound insulation cover 5. The plug-in block 801 is plugged into the fixed groove 7. A disc 802 is provided inside the fixed groove 7. A clamping block 803 is fixedly installed on the inner end of the disc 802. A clamping slot 804 is provided on the outer side of the plug-in block 801. The clamping block 803 is plugged into the clamping slot 804. A round rod 805 is fixedly installed on the outer end of the disc 802. The outer end of the round rod 805 passes through the outer side of the first sound insulation cover 4.

[0037] As a technical optimization solution of the present invention, the heat dissipation groove 13 is provided to allow the solenoid valve body 1 to dissipate heat during operation, thereby preventing the solenoid valve body 1 from overheating, thereby causing the solenoid valve body 1 to be damaged due to excessive temperature.

[0038] refer to Figures 1 to 5 The surface of the handle 810 is provided with anti-slip grooves 14, and the anti-slip grooves 14 and the handle 810 are used in conjunction with each other.

[0039] As a technical optimization solution of the present invention, the provision of the anti-slip grooves 14 can increase the stability when the handle 810 is pulled, thereby preventing the handle 810 from slipping when pulled.

At this time, the screw 12 can be rotated by a tool. The screw 12 will gradually enter the limiting groove 9, so that the pilot head body 2 and the solenoid valve body 1 can be installed, and the first sound insulation cover 4 and the solenoid valve body 1 are fitted. Then, the second sound insulation cover 5 is pushed backward. The second sound insulation cover 5 will drive the limiting rod 10 to enter the limiting groove 9. The second sound insulation cover 5 drives the insert block 801 to enter the fixed groove 7. Then, the round rod 805 can be pushed inward. The movement of the round rod 805 drives the disc 802 and the block 803 to move inward. The block 803 moves inward and enters the slot 804, thereby limiting the first sound insulation cover 4 and the second sound insulation cover 5, so that the noise of the solenoid valve body 1 can be reduced.
