Valve and sealing surface of seat seal against each other cooperation；Mainly handwheel is made of opening and closing handwheel and grinding handwheel, the fixed peace of opening and closing handwheel
Mounted in valve stem nut periphery, grinds handwheel and be connected to above opening and closing handwheel by locking pin, between centre bore and valve rod periphery
Stop nut is installed in gap cooperation, the valve rod upper end above grinding handwheel, on the valve rod between grinding handwheel and opening and closing handwheel
Locking nut is set.
Preferably, locking nut is equipped with radial handle, which is formed with the positioning with locking pin clearance fit
Hole.
Preferably, valve body by triple-valve body and charging valve body form, valve base sealing be installed in triple-valve body upper surface with into
Expect between valve body lower end face, the pilot hole with the dynamic cooperation of valve rod is equipped in valve seat Upper passage, it is close that valve clack sealing surface is located at valve seat
On the downside of cover.
Preferably, it is equipped with jam plate on the downside of opening and closing handwheel, locking device is installed between jam plate and locking pin.
The utility model has the advantages that the sealing surface to flap and valve seat can be carried out at any time by the design of grinding handwheel
Medium is removed in grinding, easy to operate, and valve seal performance is good, high reliablity, long service life.
