Brief introduction of LS920X special pressure reducing valve for coal mine
Valve is a special device automatically reduce the pipeline pressure, it can be a high pressure pipe before the valve to the valve after the piping to reduce the required level. Pressure relief valve is widely used in high-rise buildings, urban water supply network, high pressure areas, mines and other occasions to ensure that the water supply system for each point of water to receive the proper service, water pressure and flow. In view of the water leakage rate and waste degree is almost proportional to the water pressure of the water supply system, so the pressure reducing valve has the function of improving system operation, working conditions and potential water saving. According to statistics, the water saving effect is about 30%.
Construction of many types of valve, the basic principle of the past are common membrane, inner spring piston valve in the valve is to rely on local resistance to water flow to reduce the water pressure, water pressure drop range from diaphragm or piston to connect the valve of the pressure difference between the inlet and outlet automatic adjustment in recent years and some new valves, such as fixed ratio pressure reducing valve, proportional pressure reducing valve is the use of the principle of floating piston hydraulic valve weight ratio control, import and export and import and export side than the end of decompression piston area ratio is inversely proportional. This valve work smoothly without vibration, the valve body spring, so spring corrosion, metal fatigue failure of consideration, good sealing properties without water seepage, thus reduce both the dynamic pressure (water flow) and reduced static pressure (flow 0); especially the effect of water flow in the decompression at the same time.
Main function of coal mine special pressure reducing valve
Is mainly installed in the pipeline of water supply system on network. The main valve of the valve passes through the flow pressure pipe to imitate the action of the pilot valve. When the downstream pressure is lower than the set pressure, the pilot valve is opened. The water pressure above the piston is put to the downstream, faster than the speed of discharge valve up imports, the downstream pressure increases to the set value, the pilot valve closed when the downstream pressure is higher than the set value, the pressure to the top of the piston acting on the piston, the main valve moves downward, the downstream pressure is reduced to the set value, so as to maintain a constant pressure to reduce the downstream, dynamic pressure and static pressure reducing function will not affect the flow of water, the valve is mine at home * * * good
