Safety valve, pressure relief valves, safety relief valve, pressure relief valves have what differentiation?

Both pressure relief valve and safety relief valve is the same as used in the fire water and return water pressure often is likely to increase to the pipeline cannot afford the blowout, safety relief valve (pressure relief valve) at this time, but the pressure relief valve set pressure is 10 kg, the pipeline pressure is greater than 10 kg of pressure relief automatically to ensure the safety of the pipeline and the relief valve, belongs to a small thread valve, is mainly applied to gas


Relief valve: driven by static pressure before the valve is spring-loaded type pressure relief device, when static pressure is reached, the valve open rapidly to the maximum opening, exert the maximum discharge overpressure fluid, used for compressible fluid.


Pressure relief valve: driven by static pressure before the valve is spring-loaded type pressure relief device, the opening is proportional to the more than jump pressure stress increment, used for incompressible fluid.
