Fault Analysis for LPG Cut-off Valve

November 11, 2018
LPG Cut-off Valves are forced to seal the valve, so the valve is closed, the valve must be applied pressure to force the sealing surface does not leak. When the medium from the bottom of the valve into the valve six, the operating force needed to overcome the resistance is the stem and packing friction and the pressure generated by the media thrust, off the valve force than the valve opening force, so the LPG Cut-off Valves The diameter of the rod should be large, otherwise it will happen to the top of the valve stem failure. In addition to the above liquefied petroleum gas valve prone to failure, usually the following breakdown: 1, the power does not move the cause Analysis: bad power wiring connections, power supply voltage changes are not allowed within the scope of the coil short circuit or burn out. Remedy: connect the power cord, adjust the voltage within the normal range, replace the coil 2, open the valve fluid can not pass the analysis: fluid pressure or working pressure does not meet the fluid viscosity or temperature does not meet the spool and moving core Mixed impurities around the LPG Cut-off Valves, valve pre-filter or pilot valve plugging, the use of the working frequency is too high or life expectancy. Remedy: Adjust the pressure or working pressure difference or replace the suitable product, replace the suitable product, and clean the inside. Before the valve, you must install the filter valve, clean the filter or pilot valve hole in time, change the product model or replace the new product.
