Abstract
An object of the utility model is to provide a there is not wearing and tearing quck -opening valve door, including last valve body, down valve body, cylinder, cylinder mount, sealed dish, go up the valve body and pass through flange fixed connection with valve body down, go up the valve body, down the valve body junction be provided with the protruding edge that is used for the fixed cylinder mount, the cylinder fix at cylinder mount downside, the lower end of the piston rod of cylinder and sealed dish fixed connection, sealed dish cooperates with the inside sealing member of valve body down. Still include a clamping orient device, a buffer, the utility model discloses inside difficult production of seal part of valve is worn and torn, is suitable for and uses in the work occasion of high frequency switch, has overcome the problem that present valve exists, has improved life and service property (quality).
Description
Technical field
The utility model belongs to valve field, particularly relates to a kind of without wearing and tearing quick opening valve.
Background technique
Valve kind conventional at present has ball valve, butterfly valve, gate valve, the total feature of these valves is the phase mutual friction utilizing moving part and not moving part, extruding, realize the object sealed, but all there is the component wear problem at seal friction position in such valve, parts are once wearing and tearing, and valve just there will be leakage, has had a strong impact on the working life of valve.
Summary of the invention
The purpose of this utility model is to provide a kind of without wearing and tearing quick opening valve, solves the leakage easy to wear of existing valve, the problem that the life-span is short.
For achieving the above object, the technical solution of the utility model is: a kind of without wearing and tearing quick opening valve, comprise upper valve body, lower valve body, cylinder, cylinder fixing frame, seal disc, upper valve body is fixedly connected with by flange with lower valve body, upper valve body, lower valve body joint are provided with the convex edge for fixing cylinder fixing frame, described cylinder is fixed on the downside of cylinder fixing frame, and the piston-rod lower end of cylinder is fixedly connected with seal disc, and seal disc coordinates with the Sealing of lower valve inner.
Also comprise a locating guide device, described locating guide device is made up of the positioning rod be arranged on the downside of seal disc and the position shelf being arranged on lower valve inner, and described positioning rod is through the through hole on position shelf.
Also comprise a damping device, described damping device is made up of seal disc telescopic cover, spring, collar, described seal disc telescopic cover is sleeved on cylinder piston rod, one end is arranged on seal disc top, the other end is provided with spacing edge, and collar is fixedly connected on the piston-rod lower end of cylinder, with spacing along coordinating, prevent piston rod slippage, described spring is between piston rod and seal disc.
Described cylinder adopts cylindrical piston bar or T-shaped piston rod.
The utility model, seal disc is connected with cylinder piston rod, when piston rod is descending, promotes the downward straight line motion of seal disc, and arrive sealing place with lower valve body, the Sealing close contact of seal disc and lower valve body, achieves the closedown of valve; When piston rod is up, pneumatic piston just drives seal disc upwards straight line motion, and the Sealing of seal disc and lower valve body produces controlled distance, the channels open of valve body, achieves unlatching and the pipeline flow adjustment of valve.
The sealed member of the utility model valve internal not easily produces wearing and tearing, is suitable for using in the workplace of high frequency time switch, overcomes existing valve Problems existing, improves working life and service property (quality).
