safety valve, the best extra-pressure protection device takes care of press equipments,
container and on-line pipe.
The valve bonnet of sealed safety valve prevents dust and foreign matters from invading.
Meanwhile protect toxic combustible media from over flowing. it is mainly
used for the pipeline and container with steam medium . The valve bonnet of
open safety valve can favor the spring seat in lowering temperature inside of. The safety valve with a
radiator is suitable for the medium with a temperature over 350 degrees centigrade.
The springs safety valve with a lever, it makes use of open manually. When the media pressure
over 75% of setting pressure.
When mediums pressure rises over the
springs safety valve opening height is more than one fourth times of the flow diameter. It
has an advantage of discharging greatly. springs safety valve opening height is
between one twentieth to one fortieth times of the flow diameter.
Valves are divided into pressure relief valve
allowed pressure, safety valve will automatically open and fully discharge to protect the
equipment from pressure going on rising and will automatically close when the
pressure lowers to the setting pressure.
