Pneumatic valve installation and maintenance and security advice

and safe 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 limiting leverage deviant guide frame, spring loaded safety pneumatic valve to have raise a hand and prevent twisted casually adjusting screw of the device.
and the steam pressure is less than or equal to the rated. MPa boiler, safety pneumatic valve throat diameter should not less than mm; For the steam pressure is greater than the rating. MPa boiler, safety pneumatic valve throat diameter should not less than the mm.
, security pneumatic valve and connecting pipe of boiler, its cross-sectional area should not be less than safe 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.
and safe 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 at the bottom of the exhaust pipe should be put on AIRS have received safety drain pipe, on the exhaust pipe and drain pipe, are not allowed to furnish the pneumatic valve.
and evaporation capacity is greater than the rating. T/h boiler, pneumatic valve installed at least two security; The rated capacity is less than or equal to zero. T/h boiler, at least with a pneumatic valve safety. Split the economizer exit, steam superheater outlet pneumatic valve must be installed security.
and pressure vessel safety best pneumatic valve directly on the top of the pressure vessel ontology. Liquefied gas storage tank safety pneumatic valve must be installed in the gas phase. Generally available short tube connected to the container, the diameter of this security pneumatic valve spool should not be less than the safety of pneumatic valve pneumatic valve size.
, security pneumatic valve and general pneumatic valves shall not be installed between containers, containers of flammable and explosive or viscous medium, for the sake of safety of pneumatic valve easy to clean or replace, can be installed by the pneumatic valve, the cut-off pneumatic valve must be fully open during normal operation and sealing, avoid touch.
, of flammable or toxic medium pressure vessel, safety of pneumatic valve discharge medium must have a security device and recovery system. Pneumatic valve lever type safety installation must keep the vertical position, spring security pneumatic valve is installed vertically, best so as not to affect its action. When installation, also should pay attention to, and the alignment of the parts and should make the bolts evenly stress.
and new pneumatic valve should be attached to the product safety certification, after school, before installation to pneumatic valve seal and issue a safety check.
and security of the pneumatic valve export should be without resistance, avoiding the phenomenon of back pressure, if installed drainage tube, the inner diameter should be greater than the export of pneumatic valve size, safety security pneumatic valve mouth should pay attention to prevent frostbite, for holding containers of flammable or toxic, highly toxic medium, a discharge line should be straight outdoor safety facilities or have to properly handle, drain pipe not furnish any pneumatic valves.
, pressure equipments and safety between shall not contain any pneumatic valve, pneumatic valve to fill container of inflammable, explosive, toxic or viscous medium, for ease of replacement, cleaning, can be installed by the pneumatic valve, its structure and size size should not interfere with the normal operation of the pneumatic valve safety. During normal operation, by the pneumatic valve must be fully open and seal.
