Angle maze stop valve how to eliminate the drip leakage phenomenon
Over the past three years, JM100-20 angle maze shut-off valve has been used on-site for 30 sets in the Caitian Oilfield in Xinjiang, which has effectively solved the problems of dead stop of water injection main valve, leakage of stem seal, serious erosion and switch difficulties. JM100-20 angle maze shut-off valve is Xinjiang Petroleum Bureau Oil Production Technology Research Institute in 2005 to solve the injection well water injection valve seal failure, reducing the phenomenon of water hammer to reduce water damage to the equipment to extend equipment life and development, 2006 In the field application. This cut-off valve in the valve opening and closing process of high-speed, high pressure water flow better throttle, effectively reducing the flow rate of water, greatly reducing the impact of valves, pipelines and water injection equipment. In addition, the valve cut-off ball, seal the seat for a special treatment to better improve the valve erosion resistance, corrosion resistance, extending the service life of the valve. Valve to improve the stem seal packing, effectively guarantee the stem seal, reducing the resistance of the switch to stop the valve. At the same time, through the clever design of the handwheel of the cut-off valve, the switching torque of the handwheel is increased, and the handwheel is more convenient and convenient to switch. JM100-20 angle maze shut-off valve has the advantages of simple structure, convenient installation, small operation resistance, reduced labor intensity, and can save material cost over 80%.
