1, the safety valve should be installed upright and close to the protected equipment or pipeline. If not close to the arrangement, from the protected equipment or pipeline to the total pressure drop entrance pipeline safety valve, should not exceed the set pressure of safety valve 3%.
2, safety valve entrance pipe should be long radius elbow.
3, the safety valve should be set up and maintenance platform. The layout of the weight safety valve safety valve disassembly lifting may, when necessary, set the boom.
4, export pipeline safety valve shall be considered in the design of back pressure does not exceed the safety valve set pressure value. Ordinary spring-loaded safety valve, the back pressure does not exceed the safety valve set pressure value of 10%.
5, into the closed system safety valve outlet pipe should be along the media flow to 45 ° inclined discharge duct at the top, so as to avoid the duct within liquid flowing back into the pipe, and can reduce the pressure of safety valve
6, when discharged vent Explorer or go to the flare header media with the condensate liquid or gas condensate, the safety valve outlet should be higher than the duct; otherwise, measures should be taken to drain.
7, when the safety valve import and export pipeline is provided with a cut-off valve, gate valve should be selected, and lead Fengkai, valve should be installed horizontally, so as not to pin corrosion or loose connection to stem and the valve plate, valve plate down. When the safety valve with bypass valve, the valve should be sealed off.
