Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic valves, in particular to a pneumatic valve. Background Art

[0002] Pneumatic valves are valves that use compressed air to drive the movement of multiple groups of pneumatic pistons in the actuator. This type of valve uses compressed air as a power source to drive the movement of the pneumatic pistons in the actuator, thereby realizing the opening and closing of the valve. Pneumatic valves are widely used in petroleum, chemical, metallurgy, water conservancy and other fields to control the flow of various fluids, including air, water, steam, corrosive media, mud, oil, liquid metal and radioactive media. Pneumatic valves use compressed air as a power source, have fast switching speeds, are suitable for a variety of media control, and have low cost and easy maintenance. Pneumatic valves also have the advantages of anti-static function, long service life, low fluid resistance, and reliable sealing, and are suitable for various industrial automation systems; however, the pneumatic actuators currently used are fixed to the actuator bracket with multiple bolts. When the pneumatic actuator is disassembled and repaired, the staff needs to use tools to unscrew multiple bolts before the pneumatic actuator can be disassembled, which is more troublesome.
