SY42AX煤礦減壓閥 SY42AX煤礦減壓閥概述 The SY42AX coal mine special relief valve The SY42AX coal mine special relief valve overview SY42AX piston type coal mine special valve structure characteristic and use this series valve belongs to the pilot piston type pressure-reducing valve. From the main valve and pilot valve composed of two parts. Main valve mainly comprises a valve seat, the main valve disc, piston, springs and other parts. Mainly by the pilot valve seat, valve, diaphragm, spring, adjusting springs and other parts. Adjusting the spring pressure by adjusting the outlet pressure setting, using changes in outlet pressure sensing diaphragm, through the pilot valve opening and closing the main valve piston adjusting throttle position for driving the flow area of the size, to achieve decompression function. The main products are mainly used for coal mine water, pressure reducing and stabilizing role play
