High pressure Globe Valve identified as class 900 and above according to the requirements of ASME B 16.34 which normally used in the high pressure main streaming pipeline or high pressure bypass water feeding pipeline etc. The main function is to cut off/cut on or regulating the medium controlled by electric actuator or handwheel. The sealing principle of pressrue seal seal valve is sealing surface tight off under pressure and they are widely applicated in petrochmical, thermal power plant.

Submerged electromagnetic pulse valve failure and troubleshooting 1. Operating resistance is due to a small reason: short-circuit smoke, bag breakage, pressure measuring device or the main draft fan ammeter failure; Exclusion: At this time we can see the concentration of emissions to increase inspection and repair welding, Check and change the filter bag, change or repair the fan ammeter. 2. Operating resistance is due to: condensation bag, electromagnetic pulse valve does not work or damage, compressed air pressure is too low, submerged electromagnetic pulse valve poppet valve closed Strict, one or more poppet valve in a closed condition. Elimination: plugging air leakage to improve the flue gas temperature, enhance ventilation, do a good job of precipitator and pipeline insulation work; protection or replacement of submerged electromagnetic pulse valve; check the air and air Compressor Check the promotion valve and cleaning controller 3. Submerged electromagnetic pulse valve does not work due to: power failure or cleaning controller failure; electromagnetic pulse valve debris, has been a leak; submerged electromagnetic pulse Valve coil burned out; Compressed air pressure too low. Remedy: Restore power supply or repair cleaning controller Be careful to clear electromagnetic pulse valve; Replace electromagnetic pulse valve coil; Check air system and compression Machine. 4. Bag repair or exchange: Under normal circumstances, the filter bag is gradually destroyed within the service life, an important reason is the dust erosion, high temperature, high humidity caused by deterioration of the filter. Dust filter can not use the broken Bags or work, otherwise it will affect the results of dust removal.New filter bags should be replaced by the fourth test to perform, in order to increase resistance, so that the resistance of the old filter close to 5. Promotion valve does not work may be due to: power off or clear Cylinder failure or death of the cylinder; Cylinder electromagnetic solenoid valve coil burn out; Cylinder solenoid valve is dirty, ventilation port plugged or spool dry, unable to move; Compressed air pressure is too low., Luan is the national Name of the old revolutionary base areas; Elimination: to restore power supply or repair cleaning controller; Careful inspection, liquidation, repair cylinder; Exchange solenoid valve coil; Check the gas system and the compressor.
