Specific embodiment
For the technological means adopted by this utility model and the technique effect for reaching is expanded on further, below in conjunction with accompanying drawing and
Embodiment elaborates.
A kind of raw coke oven gas pipeline shearing device of this utility model, referring to figs. 1 to Fig. 3, which includes valve body 10, is fixed on valve
Ring-shaped valve seats 20 on body 10, the disc-shaped seal butterfly plate 30 for agreeing with setting with ring-shaped valve seats 20, it is connected with sealing butterfly plate 30
Support shaft 40, the cylinder 50 and the blow device 60 located at 30 rear of sealing butterfly plate that drive the rotation of support shaft 40.
The valve seat 20 is sealed using knife-edge sealing pair 70 with the sealing butterfly plate 30, the sealing on the valve seat 20
Secondary 70 is edge-shaped, and dust is easily cleared away by edge-shaped, and 70 surface of sealing pair on the sealing butterfly plate 30 is circular arc, the circle
The center of circle of arc carries out eccentric setting with the center of rotation of the support shaft 40 so that the sealing pair 70 and institute on the valve seat 20
