1, safety valve should be installed upright and close to the protected equipment or pipe. 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. 2, 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. 3, safety valve inlet pipe should be used long radius elbow. 4, safety valve outlet pipe design should 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. 5, when discharged into the vent pipe or go to the torch main medium with condensate or condensable gas, the safety valve outlet should be higher than the mains; otherwise, should take draining measures. 6, 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 to prevent the condensate within the manifold back into the branch, and can reduce the safety valve back pressure, 7, when the safety valve import and export When the pipe is provided with a shut-off valve, a single-gate valve should be used and the lead seal should be open. The stem should be installed horizontally so as to prevent the valve plate from slipping when the stem connected with the valve plate is eroded or loosened. When the safety valve with bypass valve, the valve should be sealed off.
