When installing the valve, in order to prevent metal, sand and other foreign matters from invading into the valve and damaging the sealing surface, it is necessary to set the filter and flushing valve; In order to keep the compressed air clean, oil-water separator or air filter should be set in front of the valve; Considering that the working state of the valve can be checked during operation, it is necessary to set instruments and test valves; In order to maintain the operating temperature, thermal insulation facilities are set outside the valve; In order to install the valve, it is necessary to set the safety valve and check valve; Considering the continuous operation of valves, parallel system or bypass system should be set up.
Protection measures of check valve
In order to prevent the leakage of check valve or the backflow of medium after failure, resulting in the decline of product quality and accidents, one or two shut-off valves should be set before and behind the check valve. If two shut-off valves are set, the check valve can be easily disassembled and repaired.
Protection measures of safety valve
There are three types of pressure reducing valve installation facilities. Pressure gauges are installed at the front and back of the pressure reducing valve to observe the pressure before and after the valve. There is also a fully enclosed safety valve behind the valve, so as to avoid tripping when the pressure behind the valve exceeds the normal pressure after the failure of the pressure reducing valve, including the system behind the valve.
