Abstract
The invention discloses a pressure type sealing baffle valve. The pressure type sealing baffle valve comprises a valve body, a valve cage, an air cylinder and a control system. The valve body is arranged in the valve cage, and the air cylinder is arranged outside the valve cage. The valve body comprises a rotation shaft and a baffle, the rotation shaft is connected with the air cylinder, and the baffle is installed on the rotation shaft. The control system is connected with the air cylinder. According to the mode, the position change of the valve body is achieved by sensing the air pressure inside a pipeline, then the pressure inside the pipeline can be changed, and safety use of the pipeline is guaranteed. The pressure type sealing baffle valve has the advantages of being accurate in location, compact in structure, capable of changing the pressure automatically, good in sealing performance and the like.
Description
Technical field
The present invention relates to valve, particularly relate to a kind of pressure type sealing baffle valve.
Background technique
Flap valve, it is a kind of modulating valve simple in structure, the valve butterfly valve simultaneously also can be used in mode work that the switch of low pressure pipeline medium controls refers to that closure member (flap) is disk, around valve shaft, rotate to reach a kind of valve of open and close, valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.On pipeline, main rising cut off and throttling action.
When flapper valve uses in air conduit, because air pressure in pipeline likely changes at any time, and common flapper valve can only be for cutting off the effect with throttling, can not because of pressure change in pipeline, carry out the change of valve body position, when air pressure is high, likely cause valve body to damage or Pipeline damage.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of pressure type sealing baffle valve, pressure type sealing baffle valve of the present invention, by the size of induction pipe internal air pressure, realize the change of valve body position, thereby change manifold pressure size, assurance pipe safety is used, and this flapper valve has registration, compact structure, automatically changes the features such as pressure, good airproof performance.
