[0026] A ring frame 11 is embedded in the conduit 1 , and a filter screen 12 for filtering is arranged inside the ring frame 11 , so as to filter the fluid to prevent impurities in the fluid from clogging the conduit 1 .

[0027] A sealing gasket 14 for sealing is arranged on the outer wall of the ring frame 11, and a mounting block 13 is also embedded on the outer wall of the ring frame 11 and fixed by bolts.
