[0002] The filter valve is an indispensable device for the pipeline series of conveying media. It is usually installed at the inlet end of hydraulic control valves, pressure reducing valves, pressure relief valves, water level valves and other equipment to eliminate impurities in the medium and prevent granular impurities from entering the channel and causing wall plugging, so as to protect the accessories on the equipment pipeline from wear and blockage;

[0003] For example, the patent website discloses a filter valve for water treatment (publication number: CN219954451U). This device uses a rotating screw to change the height of the filter element to adjust the horizontal relative position of the filter element and the water flow hole. However, the filter element is inside the valve body, and the staff cannot accurately adjust the rising height of the filter element. If the filter area is still at the same height as the connecting pipe after adjustment, water will still pass through the area on the filter element that has been used for a period of time, thereby reducing the filtering effect of the device. Technical personnel in this field have proposed a filter valve for water treatment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a filter valve for water treatment. The adjustment mechanism of the device can allow the filter element to be fixedly raised for a certain distance, and the distance is the same as the inner diameter of the connecting pipe, so that after adjustment, the area at the same height as the connecting pipe is unused, which solves the problems in the above background.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a filter valve for water treatment, comprising:

[0006] A valve body mechanism, wherein the valve body mechanism is the main body of the device;
