The inside of the annular slot 3 is provided with a slot 15. The inside of the slot 15 is provided with a rubber sleeve 16. The structure of the rubber sleeve 16 is set as two layers and is respectively adhered to both sides of the inside of the slot 15. The thickness of the rubber sleeve 16 is set to 2MM.

[0023] The connecting mechanism includes a fixing sleeve 4 and a clamping sleeve 5 . The top of the upper support 1 is fixedly connected with the fixing sleeve 4 , and the outer side of the fixing sleeve 4 is provided with a clamping sleeve 5 .

[0024] The outer wall of the fixing sleeve 4 is connected to the inner wall of the chuck 5 through threads. A tapered groove matching the fixing sleeve 4 is provided on the upper portion of the interior of the chuck 5 .

[0025] Insert the filter element into the slot 15. The rubber sleeve 16 in the slot 15 first contracts and then expands to clamp the filter element so as to clamp the filter element at the bottom of the annular slot 3. Insert the inlet and outlet ends into the interior of the chuck 5. Screw the chuck 5 to move downward. Use the conical groove on the upper part of the chuck 5 to squeeze the top of the fixed sleeve 4 inward and contract. Clamp the inlet and outlet ends through the fixed sleeve 4 to install the feed end on the top of the upper support 1. At this time, the inlet and outlet ends are connected to each other through the upper support 1, the lower support 2 and the filter element.

[0026] The outer side of the lower support 2 is provided with multiple threaded holes, and the outer side of the filter element is provided with a shell. Before fixing the two filter element seats to the two ends of the filter element, the shell can be pre-mounted on the outer side of the filter element. After the two filter element seats are installed, screws are used to penetrate the interior of the shell and screw into the interior of the threaded holes to connect the shell and the filter element seat as a whole. The shell protects the filter element.

[0027] The adjacent ends of the upper support 1 and the lower support 2 are fixedly connected with a flange 8, and a plurality of mounting holes 9 are distributed in an annular manner on the outer side of the flange 8. Connecting bolts 10 are inserted into the interior of the mounting holes 9, and nuts are symmetrically threaded at both ends of the connecting bolts 10. The ends of the upper support 1 and the lower support 2 with the flange 8 are connected to each other, and the positions of the mounting holes 9 on the flange 8 are aligned with each other. The connecting bolts 10 are inserted into the interior of the mounting holes 9, and the two ends of the connecting bolts 10 respectively pass through the interior of the two mounting holes 9. Then, the upper nuts are tightened at both ends of the connecting bolts 10. The nuts clamp the two flanges 8 to connect the upper support 1 and the lower support 2 as one.

[0028] One side of the lower support 2 is rotatably connected to a rotating shaft 6, one end of the rotating shaft 6 is fixedly connected to a valve core 7, the outer wall of the valve core 7 is fitted and connected to the inner wall of the lower support 2, and one side of the lower support 2 is provided with a limiting mechanism, which includes a sleeve 11, a limiting sleeve 12, a stopper 13 and a spring 14.

The outside of the rotating shaft 6 is provided with a spring 14, and the rotating shaft is fixedly connected with a movable wrench. 6 extends out of one end of the outer side of the lower support 2 and is clamped. The adjustable wrench is turned to drive the valve core 7 to rotate inside the lower support 2 through the rotating shaft 6. When the position of the valve core 7 is parallel to the end face of the lower support 2, the lower support 2 can be closed to prevent liquid from flowing into the filter element. When the position of the valve core 7 is perpendicular to the end face of the lower support 2, the channel inside the lower support 2 is opened and the liquid can flow into the filter element to control the flow rate of the liquid. The spring 14 is in a compressed state. The elastic force generated by the spring 14 cooperates with the stopper 13 to tighten the limit sleeve 12 on the outer side of the rotating shaft 6, and the limit sleeve 12 is connected to the rotating shaft 6 as a whole to limit the position of the rotating shaft 6 and prevent the rotating shaft 6 from rotating arbitrarily due to external force.

[0029] The large-flow filter element seat inserts the filter element into the interior of the card slot 15, and the rubber sleeve 16 in the card slot 15 first contracts and then expands to clamp the filter element, so as to clamp the filter element to the bottom of the annular card slot 3, and insert the inlet and outlet ends into the interior of the clamp 5, and twist the clamp 5 to move downward. The conical groove on the upper part of the inner part of the clamp 5 is used to squeeze the top of the fixed sleeve 4 inward to contract, and the inlet and outlet ends are clamped by the fixed sleeve 4 to install the feed end on the top of the upper support 1. At this time, the inlet and outlet ends are connected to each other through the upper support 1, the lower support 2 and the filter element.
