A flow-through groove 7 is opened at the upper end of the valve body 1. An anti-loosening structure 8 is installed at the front end of the fixed frame 3. The anti-loosening structure 8 includes a cross plate 9 fixedly arranged at the front end of the fixed frame 3. A first screw rod 11 is fixedly arranged at the upper end of the cross plate 9. An L-shaped plate 10 is arranged at the upper end of the first screw rod 11. A reserved groove 12 is opened inside the L-shaped plate 10. An F-shaped plate 13 is fixedly arranged on one side of the L-shaped plate 10. A limiting groove 14 is opened at the lower end of the F-shaped plate 13. The lower end of the limiting groove 14 is clamped on the outer wall of the cross bar on one side of the adjusting screw rod 4. The upper end of the first screw rod 11 passes through the reserved groove 12 and a knob is threadedly arranged at the upper end.

[0024] Refer to Figure 4 , Figure 2 and Figure 5 , it is further obtained that a magnetic attraction block 19 is fixedly arranged on the inner wall of the docking groove 18. The magnetic attraction block 19 adsorbs to one side of the fixed block 17. A plurality of second screw rods 20 are annularly and fixedly arranged at the upper end of the valve body 1. The upper ends of the second screw rods 20 pass through the fixed seat 2 and a first nut 21 is threadedly arranged on the outer wall. A sealing sleeve 5 is fixedly arranged on the inner wall where the adjusting screw rod 4 passes through the fixed seat 2. A third screw rod 22 is fixedly arranged at the upper end of the fixed seat 2. The upper end of the third screw rod 22 passes through the sealing sleeve 5 and a second nut is threadedly installed.

[0025] Specifically, the magnetic attraction block 19 adsorbs to the fixed block 17, so that the filter screen 16 is stably adsorbed and installed. The second screw rods 20 cooperate with the first nuts 21 to realize the fixed installation of the fixed seat 2 and the valve body 1. The sealing sleeve 5 is used for sealing the outer wall of the lower end of the adjusting screw rod 4.

[0026] Embodiment 2

[0027] Refer to Figure 3, and on the basis of the first embodiment, it is further obtained that an intercepting component 15 is arranged on one side of the valve body 1.
