[0039] Embodiment 1

[0040] Please refer to Figure 1-6, a self-acting valve, including a self-acting valve body 1 and a filter pipe 2. A notch 22 is formed on the lower side surface of the filter pipe 2, and a filter element is arranged on the inner surface of the notch 22. A sealing element is arranged between the filter pipe 2 and the filter element. Two mounting blocks 5 are fixedly connected to both the front and rear side surfaces of the filter pipe 2, and a fixing element for fixedly installing the filter element is slidably connected to the inner surface of the mounting block 5. The filter element includes a filter box 3, and the filter box 3 is arranged in fit with the notch 22. A filter net 31 is fixedly connected to the left side of the upper surface of the filter box 3. A clamping groove 32 is formed on the inner top surface of the filter pipe 2, and a filter hole 33 is formed on the right side of the upper surface of the filter box 3. The filter net 31 is inclined. Flange plates 21 are fixedly connected to both the left and right side surfaces of the filter pipe 2, and the filter pipe 2 is fixedly connected to the self-acting valve body 1 and an external pipeline respectively through the flange plates 21. The sealing element includes a first sealing strip 42 and a second sealing strip 43. Mounting grooves 4 are formed on both the left and right sides of the notch 22 and the filter box 3, and mounting grooves 41 are formed on both the front and rear sides of the notch 22 and the filter box 3. The first sealing strip 42 is slidably arranged inside the mounting groove 4, and the second sealing strip 43 is slidably arranged inside the mounting groove 41.

[0041] Implementation process: The liquid enters the inside of the filter pipe 2 through the external pipeline, and then enters the inside of the self-acting valve body 1 through the filter net 31. The impurities and stains carried by the liquid stay on the surface of the filter net 31. Because the filter net 31 is inclined, under the scouring of the liquid, the impurities and stains move into the inside of the filter box 3 for storage, and the water that enters the inside of the filter box 3 along with the impurities and stains enters the inside of the self-acting valve body 1 through the filter hole 33, so that the liquid entering the inside of the self-acting valve body 1 does not carry impurities and stains. At the same time, through the arrangement of the first sealing strip 42 and the second sealing strip 43, the device has good sealing performance and can effectively prevent liquid leakage.

[0042] Implementation benefits: The liquid entering the inside of the self-acting valve body 1 does not carry impurities and stains.

[0043] Example 2

[0044] The fixing element includes a fixing block 51 and an inserting block 54. Both the fixing block 51 and the inserting block 54 are slidably arranged inside the mounting block 5. A slot 52 is formed on one side of the outer surface of the fixing block 51. A spring 53 is fixedly connected between the inserting block 54 and the mounting block 5. One end of the inserting block 54 is fixedly connected with a connecting rod 55, and one end of the connecting rod 55 passes through the mounting block 5 and is fixedly connected with a connecting plate 56. The inserting block 54 is slidably arranged inside the slot 52, and one side surface of the inserting block 54 is curved.

[0045] Implementation process: After a period of use, when it is necessary to clean the inside of the filter box 3, close the self-acting valve body 1 and the external pipeline. Then, pull the connecting plate 56 to drive the connecting rod 55 and the insertion block 54 to slide inside the mounting block 5 and compress the spring 53, so that the insertion block 54 slides out of the inside of the slot 52. Then, pull the filter box 3 downward to drive the fixed block 51 to slide out of the inside of the mounting block 5. At the same time, the filter net 31 follows the filter box 3 to slide out of the inside of the filter pipe 2. Then, take out the first sealing strip 42 and the second sealing strip 43 from the inside of the first mounting groove 4 and the second mounting groove 41, which is convenient for the staff to clean the inside of the first sealing strip 42, the second sealing strip 43 and the filter box 3. After the cleaning is completed, put the first sealing strip 42 and the second sealing strip 43 back into the inside of the first mounting groove 4 and the second mounting groove 41. Then, closely fit the filter box 3 with the notch 22 again. At this time, the filter net 31 is snapped into the inside of the card slot 32. The fixed block 51 contacts the curved surface of the insertion block 54 and pushes the insertion block 54 to slide into the inside of the mounting block 5 while compressing the spring 53. The fixed block 51 continues to move upward, and the insertion block 54 is snapped into the inside of the slot 52 under the elastic force of the spring 53, thus realizing the fixation of the fixed block 51 and the filter box 3.

[0046] Benefit of implementation: Cleaning the inside of the filter box 3 is convenient to operate.

[0047] The above embodiments are only used to illustrate the present invention rather than to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement to the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
