Match with the maximum outside diameter of the sealing ring, the 4th internal diameter section of the valve seat and the maximum outside diameter of the washer match.
Preferably, the sealing ring is O shape elastic seal ring, and the washer is plain washer.
Preferably, to inside contracting, internal diameter of the outermost end of the valve body at necking is less than the outer of the washer for the necking
Diameter.
Preferably, above-mentioned valve mechanism is applied to ratio feather valve.
Compared with prior art, the utility model has the beneficial effects that: sealing ring and gasket using standard component combine
The port of necking setting improves the leakproofness of valve and the stability of structure, it is easier to replacement and maintenance.
