What multiple of the operating pressure is the set pressure of the safety valve? When the operating pressure is ≥ 0.6 MPa, the setting pressure of the safety valve should be 1.05 to 1.1 times the operating pressure ； When work pressure is high
When the operating pressure is ≥ 0.6 MPa, the setting pressure of the safety valve should be 1.05 to 1.1 times the operating pressure； Under operating pressure, it should be 1.2 to 1.25 times the operating pressure.
When the operating pressure is ≥ 0.6 MPa, the setting pressure of the safety valve should be 1.05 to 1.1 times the operating pressure； When work pressure is high
Am I ignorant? How can the set pressure have a fixed multiplicative relationship with the working pressure? In fire conditions, the start-up pressure is 1.21 times the set pressure; in other conditions, it is 1.1 times. I’m not sure if this is correct
