Liquefied natural gas (LNG) security and the characteristic of pneumatic valve

liquefied natural gas (LNG) security of pneumatic valve is used in low temperature LNG liquefied natural gas (LNG) system, under the action of open-close part affected by external forces in a normally closed state, when the equipment is low temperature or low temperature LNG liquified natural gas in the piping medium pressure than specified value, through discharge LNG liquified natural gas into the system to prevent low temperature piping or equipment within the medium pressure in excess of the prescribed number of pneumatic valve. Control of low temperature LNG liquefied natural gas (LNG) shall not exceed the specified value, to protect personal safety and equipment operation plays an important role, pneumatic valve structure of liquefied natural gas (LNG) security features:

, pneumatic valve after cryogenic treatment at low temperature, low temperature safety ability - ℃ low temperature

and low temperature safety pneumatic valve pneumatic disc material after chrome plating or nitriding process, to improve the surface hardness of the pneumatic valve stem, improve the reliability of packing seal.

and low temperature safety pneumatic valve with gasket at room temperature, low temperature state and under the temperature change can reliable sealing and resilience.

and low temperature safety pneumatic valve USES the high quality of the shield spring material, jump accurate safety.

, started freely, reliable sealing, jump pressure stability, etc.

and opening p/throat diameter, large emissions;

and the safety of pneumatic valve with the wrench, when the medium pressure to open % above, can use spanner manually open;

, thread, flange, welding, a variety of connection mode, the welding tube removable easy installation and maintenance.
