Spring loaded safety pneumatic valve 6 installation requirements

spring loaded safety pneumatic valve refers to depend on the elasticity of the spring pressure to the valves of the pneumatic valve or plunger and seal lock, once when the pressure vessel pressure produced by high pressure will be overcome after the exception safety pneumatic valve spring pressure, so the lock is open, forming a relief channel, the high pressure discharge. Suitable for liquid and gas medium, the following is a spring loaded safety pneumatic valve installation requirements, hope to help you.
spring loaded safety pneumatic valve installation requirements:
( L evaporation capacity is greater than the rating. T/h boiler, pneumatic valve installed at least two security: less than or equal to the rated evaporation. T/h boiler, at least with a pneumatic valve safety. Split the economizer exit, steam superheater outlet pneumatic valve must be installed security.
( Security pneumatic valve should be installed vertically in the pot, the top of the header. In the security between pneumatic valve and the drum or header, shall not be equipped with access steam outlet pipe and the pneumatic valve.
( Pneumatic valve lever type safety to prevent heavy hammer to mobile devices and on its own limitation lever deviant guide frame, spring loaded safety pneumatic valve to have raise a hand and prevent twisted casually adjusting screw of the device.
( For the steam pressure is less than or equal to the rated. MPa boiler, safety pneumatic valve throat diameter should not less than the mm: for steam pressure is greater than the rating. MPa boiler, safety pneumatic valve throat diameter should not less than the mm.
( Safety of pneumatic valve and connecting pipe of boiler, its cross-sectional area should not be less than the safety import cross-sectional area of pneumatic valve. If several security pneumatic valve installed on a common attached directly to the drum on the spool, spool access cross-sectional area should not step in pneumatic valve exhaust all security area. Times.
( Safety exhaust pipe of pneumatic valve should be installed commonly exhaust steam pipe should be road safety, and have enough area, ensure the exhaust steam flow. Security pneumatic valve exhaust pipe should have received safety at the bottom of the drain pipe, on the exhaust pipe and drain pipe, are not allowed to furnish the pneumatic valve.
