The clamping component 3 includes a mounting block 12, a sliding hole 13, a clamping rod 14, a mounting cavity 15, a second compression spring 16, a limiting block 17 and an inserting block 18. The fixing block 6 is fixedly installed on one side of the outer surface of the upper end of the solenoid valve 1. One end of the outer surface of the lower end of the support rod 7 is fixedly connected with one end of the outer surface of the upper end of the fixing block 6. The outer surface of the lower end of the mounting bracket 4 is fixedly connected with the middle of the outer surface of the upper end of the mounting block 12.

[0027] The installation groove 8 is opened in the middle of the outer surface of the upper end of the support rod 7, the clamping hole 9 is opened in the upper part of the outer surfaces on both sides of the support rod 7, one end of the clamping hole 9 communicates with the installation groove 8, the insertion slot 10 is opened at the bottom of the installation groove 8, and the first compression springs 11 are fixedly installed on both sides of the bottom of the insertion slot 10; the insertion block 18 is fixedly installed on the outer surface of the lower end of the installation block 12, the installation cavity 15 is opened inside both ends of the installation block 12, the sliding hole 13 is opened in the middle of the outer surfaces on both sides of the installation block 12, and one end of the sliding hole 13 communicates with the installation cavity 15; the second compression spring 16 and the limiting block 17 are both located in the installation cavity 15, one end of the outer surface of the second compression spring 16 is fixedly connected to one end of the installation cavity 15 far from the sliding hole 13, the other end of the outer surface of the second compression spring 16 is fixedly connected to the middle of the outer surface of one side of the limiting block 17, the clamping rod 14 is fixedly installed on the middle of the outer surface of the other side of the limiting block 17, and the clamping rod 14 penetrates through the sliding hole 13; the outer wall of the clamping rod 14 is slidably connected with the sliding hole 13, one side of the outer surface of the limiting block 17 is elastically connected to one end of the installation cavity 15 through the second compression spring 16, and the outer wall of the limiting block 17 is slidably connected with the installation cavity 15; the outer wall of the installation block 12 is inserted into the installation groove 8, the outer wall of the insertion block 18 is inserted into the insertion slot 10, and the outer wall of one end of the clamping rod 14 is clamped with the clamping hole 9.

[0028] It should be noted that the present utility model is a solenoid valve capable of self-checking for faults. The solenoid valve 1 described in the text belongs to the prior art and can be effectively known to those skilled in the art of the relevant technical field, so specific details will not be elaborated here. By setting the noise sensor 5, the noise sensor is used to determine whether the solenoid valve is faulty, mainly relying on the analysis of the type and frequency of the noise generated by the solenoid valve. For example, if the internal parts of the solenoid valve are worn or loose, it may cause excessive noise; overheating of the coil or problems with the drive circuit may produce a low and continuous noise; while the short and sharp noise during startup or shutdown may be a normal phenomenon. Therefore, by setting the noise sensor 5, the function of self-checking for faults can be achieved, and timely feedback can be made to avoid causing significant economic losses. The noise sensor 5 is fixed on the mounting bracket 4, and the mounting bracket 4 is fixed on the upper outer surface of the mounting block 12 in the clamping component 3. When the clamping component 3 is clamped with the bracket structure 2, by squeezing the clamping rod 14, the clamping rod 14 slides along the sliding hole 13, and the clamping rod 14 drives the limiting block 17 to squeeze the second compression spring 16 in the mounting cavity 15, so that one end of the clamping rod 14 enters the sliding hole 13. Then, the mounting block 12 is inserted into the mounting groove 8 from top to bottom, so that the insertion block 18 is inserted into the insertion slot 10 to squeeze the first compression spring 11. When the clamping rod 14 reaches the position of the clamping hole 9, due to the reset action of the second compression spring 16, one end of the clamping rod 14 is driven to be clamped into the clamping hole 9 to complete the installation. After the installation is completed, the first compression spring 11 is in a compressed state. Through the reaction force of the first compression spring 11, the clamping stability between the clamping rod 14 and the clamping hole 9 can be enhanced, thereby increasing the stability of the noise sensor 5 after installation.
