DETAILED DESCRIPTION

[0026] In order to make the purpose and advantages of the utility model more clear and apparent, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the specific protection scope requested by the utility model.

[0027] As Figures 1-5 shown, an electromagnetic valve impurity inhibition device, comprising an electric control part 1, the bottom of the electric control part 1 is fixedly installed with a valve cover 2;

[0028] The bottom of the valve cover 2 is fixedly installed with a valve seat 3, one side of the valve seat 3 is provided with an impurity inhibition mechanism 4, and the bottom of the valve seat 3 is provided with an anti-blocking mechanism 5;

[0029] Among them, the impurity inhibition mechanism 4 includes a cylinder body 41, and the cylinder body 41 is provided with a filter hole 42 on one side;

[0030] The anti-blocking mechanism 5 includes a connecting pipe 51 and a spring 55, the middle of the connecting pipe 51 is fixedly connected with a shell 52, the inside of the shell 52 is fixedly installed with a fixed block 53 and a partition 56, and the spring 55 is sleeved outside the blocking piece 54.

[0031] Referring to the accompanying Figure 1 and Figure 2 , in the embodiment, the electric control part 1 drives the valve cover 2 to drive the valve core 6 to move vertically, so that the valve core 6 and the diaphragm 7 move linearly in the inside of the valve seat 3, and the diaphragm 7 is clamped between the valve cover 2 and the valve seat 3.

[0032] In the above embodiment, the valve core 6 and the diaphragm 7 can be driven to move up and down by starting the electric control part 1, so that the valve core 6 is opened and closed with the valve seat 3, and the start and stop of the electromagnetic valve are realized.

[0033] Referring to the accompanying Figure 3 , Figure 4 and Figure 5 , in the embodiment, the cylinder body 41 is threadedly installed with the valve seat 3, and one end of the connecting pipe 51 is located at one end of the cylinder body 41.

[0034] In the above embodiment, the surfaces of the two ends of the cylinder body 41 are provided with thread grooves, so that one end of the cylinder body 41 can be threadedly installed with the valve seat 3, and the other end can be connected with the fluid pipeline outside.

[0035] Further, since the filter holes 42 are arranged in plurality and penetrate the cylinder 41, the impurities in the fluid can be filtered when the fluid passes through, and part of the filtered fluid enters the connecting pipe 51 through the valve seat 3 and enters the inside of the shell 52.

[0036] Specifically, since the spring 55 abuts between the fixed block 53 and the partition plate 56, and the spring 55 can push the plug 54 to abut against the partition plate 56, when the fluid enters, the plug 54 can be pushed to move, since one end of the plug 54 is slidingly installed with the partition plate 56, and the other end of the plug 54 is slidingly installed with the fixed block 53, so that the spring 55 can be compressed, that is, the fluid can pass through the partition plate 56 and return to the inside of the valve seat 3 through the connecting pipe 51 to the side of the filter hole 42.

[0037] Referring to the accompanying drawings Figure 1 , Figure 3 and Figure 4 In the embodiment, the valve seat 3 includes the fluid inlet 31 and the through hole 34, the fluid inlet 31 is communicated with the limiting cylinder 33 through the fluid outlet 32, and the bottom of the through hole 34 is communicated with the connecting pipe 51.

[0038] In the above embodiment, since the through hole 34 penetrates the valve seat 3 and is located in the inside of the limiting cylinder 33, part of the filtered fluid can enter the inside of the connecting pipe 51 through the through hole 34, so as to return to the inside of the fluid inlet 31 to flush the filter hole 42, since the valve core 6 and the diaphragm 7 are located at the top of the limiting cylinder 33 and abut against the limiting cylinder 33, the valve core 6 can be driven to leave the top of the limiting cylinder 33 when the electric control part 1 is started.

[0039] The working principle of the utility model is as follows: after the cylinder 41 is fixedly installed in the inside of the valve seat 3, the fluid inlet pipe is connected with the cylinder 41, the fluid enters the inside of the cylinder 41, after the impurities in the fluid are filtered through the filter hole 42, the filtered fluid enters the fluid outlet 32 through the limiting cylinder 33, so as to flow out of the inside of the valve seat 3, and part of the filtered fluid enters the inside of the connecting pipe 51 through the through hole 34, the fluid enters the shell 52 through the connecting pipe 51, and pushes the plug 54 to move to one side, and compresses the spring 55 at the same time, the fluid passes through the partition plate 56 and enters the fluid inlet 31 again through the connecting pipe 51, so as to flush the filter hole 42 of the cylinder 41, and avoid the filter hole 42 from being blocked.

[0040] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
