Explosion-proof gear pump safety valve installation and piping layout design points First, explosion-proof gear pump safety valve should be installed upright and close to be protected equipment or pipes. If not close to the arrangement, the total pressure drop across the pipe from the protected equipment or pipe to the safety valve inlet shall not exceed 3% of the pressure relief valve value.
Second, the safety valve should be set overhaul platform. Arrange the weight of the safety valve to consider when lifting the safety valve may be hoisted, if necessary, should be set boom. Botou City Taibang Valve Manufacturing Co., Ltd. production of products
Third, explosion-proof gear pump inlet pipe safety valve should be used long radius elbow.
Fourth, the safety valve outlet pipe should be designed to consider the back pressure does not exceed the pressure relief valve certain value. For ordinary spring-type safety valve, the back pressure does not exceed 10% of the pressure relief valve.
Fifth, when discharged into the vent pipe or to the torch of the medium with condensate or condensable gas, the safety valve outlet should be higher than the mains; otherwise, should take draining measures.
Sixth, into the closed system safety valve outlet pipe should be along the flow of medium 45 ° obliquely connected to the top of the discharge manifold, Po Taibang to avoid condensate within the main pipe back into the branch, and can reduce the safety valve back pressure
Explosion-proof gear pump When the safety valve inlet and outlet pipe with cut-off valve should be used single gate valve, and lead seal open, the stem should be installed horizontally, so as to prevent the valve stem and valve plate connected to the corrosion or loose pin, Valve plate down. When the safety valve with bypass valve, the valve should be sealed off.
