Seat, the valve plate upper center activity are plugged with valve shaft, and activity is plugged with short axle, and short axle and valve shaft in the middle part of the valve plate lower end
Activity runs through grafting sealing structure, and the sealing structure includes sealing footmuff, disk spring, sealing ring and O-ring, the valve
The outer lower portion movable sleeve of axis is connected to sealing footmuff, and the sealing footmuff lower end, which abuts, disk spring, under the disk spring
End abuts sealing ring, and the sealing ring lower end inside is equipped with groove, is equipped with O-ring in the groove.
Preferably, the body cavity upper and lower ends are equipped with mounting groove, and sealing structure is mounted in mounting groove.
Preferably, the outer surface of the valve plate and valve seat, which is poured, is equipped with vulcanised rubber layer.
Preferably, run through center symmetric setting of the sealing structure of grafting relative to valve plate on the short axle and valve shaft.
Compared with prior art, the utility model has the beneficial effects that the corrosion-resistant butterfly valve end face seal structure of this kind of full lining,
By the way that sealing structure is arranged, O-ring is fitted snugly on valve shaft, then the elastic force for cooperating disk spring to give sealing ring, makes to seal
Closely activity is plugged in mounting groove ring, realizes the sealing for the first time to butterfly valve end face, when fluid challenge sealing ring, dish
Spring stress will squeeze and seal footmuff, make to seal footmuff abutting mounting groove, realize the secondary seal to butterfly valve end face, improve
The effect of sealing avoids liquid leakage corrosion periphery other equipment.
