EMERGENCY RELIEF HATCH


WHAT IS EMERGENCY RELIEF HATCH?
Different from the general emergency venting device, it sets the required presure based on the Tension rod, 
and has exellent sealing capacity compared to the existing weight type/oil seal type/spring type product.
Moreover, in case of oil seal type, it has relatively lower reliability since its setting pressure is not 
even for the difference of viscosity by temperature, but this device so adopts the feature of Tension rod 
that it has high fidelity for the setting pressure. It is used in vessel LNG Tank and ground storage tank. 
It is a device to release the pressure by opening the cover with rupturing of tension rod due to overpressure.

DESCRIPTION
KSRH Model is a device to relieve the pressure by
opening the cover with rupturing the specially
designed Tension rod when it is occurred the
overpressure or reached to the setup pressure.

FEATURES
■Excellent sealing capacity : no leakage compared
  to the existing Emergency vent cover
■Specially designed Tension rod; high fidelty for
  setting pressure
■Equipping Sealing Diaphragm
■Available on LNG vessel and ground tank
■Possible to set to lower pressure
■Low maintenance fee since it is possible to reset of
  it after rupturing by replacing with new one
