Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-4, one kind is surged Wedge Gate Valves, including valve body 1, and the both ends of valve body 1 are fixedly welded with ring flange 7, valve
The top of body 1 is threaded with installation lid 3, installs lid 3 far from the side of valve body 1 and has been bolted hydraulic cylinder 4, hydraulic cylinder
4 output end has been bolted to connection connecting rod 5, and the outer wall of the output end of hydraulic cylinder 4 is fixedly attached with installation lid 3,
Connecting rod 5 is fixedly welded with connecting plate 2 far from one end of mounting rod, and the side of connecting plate 2 is fixedly connected with safety spring 6, and
The other end of safety spring 6 is fixedly connected with installation lid 3, and connecting plate 2 is fixedly welded with valve plate 9, valve far from the side of installation lid 3
The two sides of plate 9 are provided with sealing ring 12, and sealing ring 12 is fixedly connected with valve body 1, and sealing ring 12 is internally provided with air bag 11,
Valve plate 9 is provided with air bag 13 far from one end of connecting plate 2, and air bag 13 is fixedly connected with valve body 1, connection in air bag 13
There is ring spring 14, one end of air bag 13 is connected with connecting tube 15, and the other end of connecting tube 15 is connected with air bag 11, valve
Body 1 is threaded with spare lid 10 far from the side of installation lid 3, and the intermediate thread of spare lid 10 is connected with threaded rod 8, installation lid
3 are fixed with cushion close to the side of hydraulic cylinder 4, and hydraulic cylinder 4 is arranged above cushion, and cushion uses rubber material, delay
Buffer spring is inlaid in punching pad, air bag 13 is filled with inert gas, and sealing ring 12 uses rubber material, and threaded rod 8 is close
