(1) Before installing the valve, its model should be verified according to the design documents, and its installation direction should be determined according to the flow direction of the medium. Check the valve packing, and there should be an adjustment margin left for the gland bolts.
(2) When the valve is connected to the pipeline by flange or thread, the valve should be installed in the closed state. When connected by welding, the valve should not be closed, and argon arc welding should be used for the bottom layer of the weld.
(3) The safety valve should be installed vertically. The final adjustment of the safety valve should be carried out on the system, and the opening and reseating pressures should comply with the provisions of the design documents. After the safety valve is finally calibrated and qualified, it should be sealed with lead and the "Safety Valve Final Debugging Record" should be filled out.
