Micro spring type safety features and applications of pneumatic valve

security pneumatic valve is a kind of automatic pneumatic valve, is a kind of special equipment. Security role of pneumatic valve is the protective equipment, when the pressure inside the container equipment to ratings, then safety pressure pneumatic valve components will start pressure, the pressure inside the equipment back to normal working stress. Pneumatic valve according to the structure safety mainly divided into three, spring loaded safety pneumatic valve, pneumatic valve lever type safety, pulse pneumatic type safety valve ( Pilot operated safety pneumatic valve. Here mainly to talk about spring type safety pneumatic valve, spring loaded safety action principle of the pneumatic valve is through the pneumatic valve internal spring to adjust pressure, increased when the pressure in the equipment, to achieve the highest rating, spring will be jacking pneumatic disc pressure, purpose is to achieve equipment within the working pressure in a normal range. The spring loaded safety pneumatic valve according to the height of the opening is divided into full rev type safety pneumatic valve, pneumatic valve and raise safety all rev type pneumatic valve is pneumatic safety disc height, maximum open is generally refers to the pneumatic disc opens at/runner diameter greater than or equal to, all rev type pneumatic valve safety in general medium mainly for steam, air, of course, also have according to the actual working condition, medium for liquid device, also can use the pneumatic valve type safety. Safety mini rev type pneumatic valve, generally refers to the opening height of the pneumatic valve for pneumatic valve seat throat diameter / ~ /, with complete opening and pneumatic valve type safety, safety mini rev type pneumatic valve in general is mainly suitable for water, liquid medium. Our common safety mini rev type pneumatic valve models have A, A, A, A, etc. Safety mini rev type pneumatic valve is suitable for the liquid medium. Emissions of toxic or flammable medium, must choose closed-end security pneumatic valve. Should be paid attention to when choosing safety pneumatic valve, characteristic of medium, temperature, corrosion resistance is suitable for the requirement of the pneumatic valve materials and seal materials. Security pneumatic valve generally apply to clean, no particles, low viscosity fluid.
