Abstract

The invention discloses a novel pneumatic butterfly valve. The pneumatic butterfly valve comprises a butterfly valve body, a pneumatic actuator and a controller, wherein the butterfly valve body comprises a valve chamber, an elastic valve seat, a valve disc and a valve rod; the controller comprises a casing, an air source connector, air outlets and a solenoid valve, the air outlets comprise a first air outlet connected with the pneumatic actuator and a second air outlet connected with the elastic valve seat, the air source connector is connected with the solenoid valve, and the solenoid valve is connected with the first air outlet and the second air outlet respectively; an air inlet for inflating the elastic valve seat is arranged on the valve chamber and communicated with the second air outlet through an air pipe. The pneumatic butterfly valve is simple in structure, reasonable in arrangement, convenient to mount and dismount and attractive in appearance; meanwhile, an action air path of the pneumatic actuator and an inflation air path of the elastic valve seat can be controlled, so that abrasion during opening and closing of the valve disc and the valve seat can be reduced, and the sealing performance during closing of the valve disc and the valve seat can also be guaranteed.

Description

technical field [0001] The invention relates to a valve, in particular to a novel pneumatic butterfly valve. Background technique [0002] For a long period of time, domestic inflatable sealing special valves have been monopolized by foreign products. Foreign brand inflatable butterfly valves headed by American Aerodynamics have occupied almost all pipelines and pumps in pneumatic conveying. Due to the operation of these brand valves The control is heavily dependent on the user's industrial control equipment and system, and is limited by the user's actual use environment and the level of installation and debugging of the workers. Up to 70% of the damage is caused by the control system - that is, 70% of the service life of the valve Worn out from abnormal early wear and damage. [0003] Butterfly valve pneumatic mechanism is a mechanical and electrical integration component specially serving pneumatic inflatable butterfly valves and dome valves. It is generally composed of a...
