Abstract
The invention aims to provide a wear-free quick opening valve. The wear-free quick opening valve comprises an upper valve body, a lower valve body, an air cylinder, an air cylinder fixing frame and a sealing disc. The upper valve body and the lower valve body are fixedly connected through a flange. A convex edge used for fixing the air cylinder fixing frame is arranged on the connecting portion of the upper valve body and the lower valve body. The air cylinder is fixed to the lower side of the air cylinder fixing frame. The lower end of a piston rod of the air cylinder is fixedly connected with the sealing disc. The sealing disc is matched with a sealing element in the lower valve body. The wear-free quick opening valve further comprises a positioning guide device and a buffer device. The sealing element in the valve is not prone to wear, so that the wear-free quick opening valve is suitable for being used in workplaces where the valve is opened or closed at high frequency; the problems of an existing valve are solved, the service life is prolonged, and the use quality is improved.
Description
Technical field
The invention belongs to valve field, particularly relate 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 object of the present invention is to provide a kind of without wearing and tearing quick opening valve, solve the leakage easy to wear of existing valve, the problem that the life-span is short.
For achieving the above object, technological scheme of the present invention 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 present invention, 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 valve internal of the present invention 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).
