The medium enters the slot of the filter frame 5 from the filter tube 2, and the impurities in the medium are blocked by the filter frame 5 to filter the impurities in the medium. The medium passes through the filter frame 5 and flows into the flow control valve body 1, and then flows out of the flow control valve body 1. When there are many impurities blocked in the filter frame 5, the flow rate will decrease. At this time, the corresponding valve of the pipeline is closed to stop the medium from flowing into the filter tube 2. The personnel pulls the fastening column 12 to squeeze and deform the elastic component 14 by the fastening plate 13. One end of the fastening column 12 leaves the annular groove 11 formed by the threaded bolt 10, and then the bottom end of the threaded bolt 10 leaves the top of the sealing plate 4 by rotating the threaded bolt 10, and then the personnel pass By pulling the fixing plate 6, the fixing plate 6 slides in the guide groove 7 through the guide bar 8, and the fixing plate 6 leaves the installation groove. The personnel take out the sealing plate 4 in the sealing groove, so that the filter frame 5 at the bottom end of the sealing plate 4 can be taken out, so as to facilitate cleaning of impurities in the filter frame 5. After cleaning, the filter frame 5 is pressed against the filter tube 2. At this time, the sealing plate 4 seals the sealing groove, and then the fixing plate 6 is pushed. The fixing plate 6 blocks the installation groove, and the threaded bolt 10 is just above the sealing plate 4. The limiting mechanism between the guide bar 8 and the guide groove 7 can prevent the guide bar 8 from being separated from the guide groove 7 by the vertical force. Then, by rotating the threaded bolt 10, the bottom end of the threaded bolt 10 is pressed against the sealing plate 4, so that the sealing plate 4 is stably and reliably fixed in the sealing groove.The limiting mechanism can prevent the fixing plate 6 from leaving the installation groove. At this time, the fastening column 12 is aligned with the annular groove 11 of the threaded bolt 10. The fastening plate 13 is supported by the elastic component 14. The fastening plate 13 drives the fastening column 12 to move. One end of the fastening column 12 is against the annular groove 11, thereby preventing the threaded bolt 10 from loosening. It can ensure that the sealing plate 4 can stably and reliably seal the sealing groove, so that the filter frame 5 can reliably filter impurities from the medium, effectively preventing impurities from affecting the normal operation of the flow control valve body 1 and causing damage to the valve.

[0024] In this embodiment, an arc groove is provided at one end of the fastening column 12, and the arc groove is adapted to the annular groove 11. By adapting the arc groove provided at one end of the fastening column 12 to the annular groove 11, one end of the fastening column 12 can be more stably pressed against the annular groove 11.

[0025] In this solution, a handle is provided at the other end of the fastening column 12, which makes it convenient for people to hold and pull the fastening column 12, and is easy to use.

[0026] In this solution, a hand-holding groove 15 is provided at the top of the sealing plate 4. The two hand-holding grooves 15 are symmetrically arranged. By providing two symmetrically arranged hand-holding grooves 15, it is convenient for a person to lift the sealing plate 4 upward by holding the two hand-holding grooves 15.

[0027] In the present embodiment, the limiting mechanism includes a limiting groove 16 and a limiting block. The limiting groove 16 is opened on one side of the bottom end of the guide groove 7. The limiting block is located in the limiting groove 16. The limiting block is connected to the guide bar 8. The limiting block connected to the guide bar 8 is located in the limiting groove 16, which can effectively prevent the fixing plate 6 from leaving the installation groove when the threaded bolt 10 is rotated, thereby ensuring that the bottom end of the threaded column effectively supports the sealing plate 4.

[0028] In this solution, two guide mechanisms are provided and are symmetrically arranged. By providing two symmetrically arranged guide mechanisms, the fixing plate 6 can slide linearly in the installation groove more stably.

[0029] In this solution, a plurality of elastic components 14 are provided, and the fastening plate 13 can be supported more stably by providing a plurality of elastic components 14 .

[0030] In this solution, the elastic component 14 is a spring. Since the elastic component 14 is a spring, the spring has good elasticity and can better support the fastening plate 13 .
