Cryogenic Pressure Relief Valve Micro Open Safety Valve For LNG
Station
Product overview of spring micro-start closed safety valve
The spring micro-open closed safety valve refers to the valve's
valve or plunger and other seals are locked by the elastic pressure
of the spring.Once the pressure of the pressure vessel is abnormal,
the high pressure generated will overcome the spring pressure of
the safety valve, so the locking device is topped Open, forming a
pressure relief channel to release high pressure.
The spring micro-lift closed safety valve is different from the
general full-lift safety valve. It can be automatically closed
after pressure relief, without human manual reset. Some of our
spring micro-lift closed safety valves are suitable for LPG with
operating temperature ≤300℃ , Air, water and other media equipment
or pipelines. Some of our stainless steel safety valves are
suitable for equipment or pipelines with corrosive media at
operating temperatures ≤200°C, as overpressure protection devices.
Main items of safety valve order
Safety valve medium, pressure level, opening method (full
start/micro start), set take-off pressure, determine valve size,
connection method, standard maximum temperature resistance, release
flow rate/hour, valve body material, internal valve body structure,
working principle , Installation instructions and other relevant
technical data. The main basis for safety valve selection is (the
take-off pressure and tidy pressure flow temperature) caliber will
be given by the general design institute, and in fact through steam
pressure, flow rate and take-off pressure, you can guess the safety
valve Size. Generally, it will be one size smaller than the caliber
selected by the design institute. When the use occasion is very
important or the environment is more complicated, please provide
the design drawings and detailed parameters as much as possible.
Our company experts will review and check for you.
