Inching valve spring is a compression spring to balance the force acting on the valve of the force. Spiral ring-shaped spring compression spring by rotating it inching valve above the adjusting nut to adjust, you can use this structure (tuning) pressure relief valve opening as needed correction. Spring inching valve structure is compact and lightweight valve Shandong, sensitivity is relatively high stainless steel valves, cast steel valves installation location is not limited, but also because of the sensitivity of the vibration is small, it can be used on mobile pressure vessel. Opening pressure adjustment: in the nameplate range spring working pressure level, by turning the adjustment screw to change the amount of compression spring can be adjusted to opening pressure. Before the rotation adjustment screw, the valve inlet pressure should be reduced to 90% of the opening pressure of the following, in order to prevent the valve is rotated when the rotation adjustment screw, which damage the sealing surface. When the pipeline medium pressure exceeds a predetermined pressure value, the auxiliary valve to open the valve, the media along the catheter into the main valve and the main valve is opened to reduce the media pressure increased. Emissions safety valve depends on the caliber of the valve seat and valve opening height, it can be divided into two types: Weiqi opening height is the seat diameter (1/20) - (1/40), the entire Kai It is (1/3) - (1/4).
