Y43H steam pressure relief valve is mainly used in steam pipelines, which is suitable for steam pipelines with large flow and large inlet pressure changes.Working principle of steam pressure relief valve:The Y43H steam pressure relief valve uses the opening and closing parts in the valve body to adjust the flow rate of the medium and reduce the pressure of the medium. At the same time, the opening and closing part is adjusted with the effect of the effect of the pressure behind the valve, so that the rear pressure of the valve is kept within a certain range. Under the condition of changing inlet pressure, the outlet pressure is kept within the set range to protect the production equipment behind the valve.Steam pressure relief valve execution standard:GB/T 21386-2008 scale pressure relief valveJB/T 2205-2000 pressure relief valve structure lengthGB/T 12245-2006 pressure relief valve performance test methodGB/T 12244-2006 General requirements for pressure relief valves
