DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] An anti-clogging temperature control valve, such as Figures 1 to 6 As shown, it includes a valve body 1, the valve body 1 is provided with an outlet end 2 and an inlet end 3, the inlet end 3 is provided with a mounting groove 4 corresponding to the inlet end 3, a filter group 5 is arranged in the mounting groove 4, the filter group 5 includes two separate filter components 6, and each of the filter components 6 includes a detachable filter plate 7.

[0024] refer to Figure 3 , Figure 4 and Figure 5 As shown: the filter group 5 also includes a mounting plate 8, the mounting plate 8 is arranged corresponding to the mounting groove 4, the mounting plate 8 is used to block the inlet end 3, mounting ears 24 are integrally formed on both sides of the mounting plate 8, mounting surfaces corresponding to the mounting ears 24 are provided on both sides of the mounting groove 4, and corresponding mounting holes are provided on the mounting surfaces and the mounting ears 24, two mounting rings 9 are integrally formed on the mounting plate 8, two connecting tubes 10 are integrally formed in the mounting ring 9, the two connecting tubes 10 are respectively provided with first through pipes 11 corresponding to the two sides of the mounting plate 8, and a filter box 12 is detachably installed on the mounting ring 9.

[0025] In the above embodiment, by opening a first through pipe 11 on the mounting plate 8 and communicating with both sides of the mounting plate 8, the fluid flows from the inlet end 3 into the filter box 12 through the first through pipe 11 and then flows into the interior of the valve body 1 through the first through pipe 11, so that the filter box 12 can filter impurities in the fluid.

[0026] refer to Figure 3 , Figure 4 and Figure 5As shown: a limiting groove 13 is provided on the mounting ring 9, a limiting ring 14 corresponding to the mounting ring 9 is integrally formed on the filter box 12, a limiting rod 15 corresponding to the limiting groove 13 is integrally formed on the limiting ring 14, an annular connecting part 16 is rotatably connected to the mounting ring 9, a male thread is provided on the inner wall of the annular connecting part 16, and a female thread corresponding to the male thread is provided on the outer peripheral wall of the filter box 12.

[0027] One end of the filter box 12 is integrally formed with two second through pipes 17 corresponding to the two connecting pipes 10 , and one end of the filter box 12 away from the second through pipes 17 is provided with a positioning groove 18 for installing the filter plate 7 , and the positioning groove 18 is set between the two second through pipes 17 .

[0028] In the above embodiment, the filter box 12 is installed on the limiting ring 14 through the annular connecting portion 16. The correspondence between the limiting rod 15 and the limiting groove 13 enables the filter box 12 to connect the two connecting tubes 10 with the two second through tubes 17 to prevent the filter box 12 from rotating. The filter plate 7 is fixed by the positioning groove 18 set between the two second through tubes 17, so that the filter plate 7 filters the fluid in the second through tube 17 on one side of the filter box 12, and then transports the fluid to the inside of the valve body 1 through the second through tube 17 on the other side.

[0029] refer to Figure 3 , Figure 4 and Figure 5 As shown: the filter box 12 is threadedly connected to a cover plate 19 on one side away from the second through pipe 17, and a clamping plate 20 corresponding to the filter plate 7 is integrally formed in the cover plate 19. A groove body 21 connected to the first through pipe 11 is provided on one side of the mounting plate 8, and a sealing plate 22 is slidably installed in the groove body 21, and a through hole 23 corresponding to the first through pipe 11 is provided on the sealing plate 22.

[0030] In the above embodiment, when the filter plate 7 needs to be replaced, the sealing plate 22 is slid so that the two through holes 23 on the sealing plate 22 are separated from the first through pipe 11, and then the first through pipe 11 is blocked by the sealing plate 22. Then, the filter box 12 is opened by rotating the cover plate 19, and the filter plate 7 is disassembled for replacement.

[0031] Working principle:

[0032] When the temperature control valve is operating, the fluid is transported to the filter box 12 through the first through pipe 11, the connecting pipe 10 and the second through pipe 17, and then filtered by the filter plate 7 in the filter box 12, and then transported to the inside of the valve body 1 through the second through pipe 17, the connecting pipe 10 and the first through pipe 11 on the other side to prevent impurities in the fluid from accumulating in the valve body 1. At the same time, two of the above-mentioned working cycles are arranged on the mounting plate 8, so that when the filter plate 7 needs to be replaced, the staff will pull the sealing plate 22 set on the same group of first through pipes 11, so that the through hole 23 on the sealing plate 22 is away from the first through pipe 11, so that the sealing plate 22 completely blocks the first through pipe 11, and then the staff rotates the cover plate 19 to disassemble and replace the filter plate 7, so that the temperature control valve can replace the filter plate 7 without stopping operation.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
