Secondly, the surface of the support block 10 is inclined and inclined to the drain hole 12. In this way, it can be ensured that the water flow of the closure plate 9 converges to the support block 10 and then converges to the drain hole 12 in the support block 10, and is discharged from the valve 1 into the cavity 11.

Secondly, when it needs to be reset, the piston rod 26 is continuously pushed to a position where it cannot be pushed, and then the insert 33 is rotated, so that the piston rod 26 is re-embedded in the groove one 32 of the contact block 31, thereby achieving connection, and the insert 33 is slidably connected with the hand wheel 36, and is embedded in the valve stem 5 to move synchronously with the valve stem 5.
