ZXDA pneumatic discharge valve FL641W, pneumatic with manual discharge valve, aerodynamic-expanding discharge valve, the pneumatic-expanding discharge valve, the reactor discharge valve manually with pneumatic discharge valve product overview a pneumatic discharge valve work Principle: 1, easily turn the hand wheel, the shift handle goes to (sub) signs can be pneumatically operated. 2, when the air supply into the solenoid valve, solenoid valve automatically open on the brutal (or lower) gas port solenoid valve power, the valve automatically opens the valve when power is turned off automatically. Red button for the manual debugging switch button. 3, when the upper air into the cylinder, the piston into the lower part, that is to close the valve. 4, when the air supply into the lower cylinder, the piston into the upper part, that is to open the valve. 5, continuous operation, as described above and from power. Second, the manual discharge valve works: 1, turn off gas supply, in the absence of air pressure, relaxed handwheel gradually push to move the switching lever (combined) signs, can be manually operated. 2. Turn handwheel counterclockwise valve open, valve closed clockwise. Third, the pneumatic actuator routine maintenance: 1, nitrogen should be kept dry and clean, regular filter water. 2, to maintain normal nitrogen pressure (0.4 ~ 0.7Mpa), part of the electrical power signal no short circuit or open circuit failure, to prevent water, to ensure that the solenoid valve and reply switch is working properly. 3, under normal operating conditions, inspection once a month, once a year overhaul. Fourth, manually with pneumatic discharge valve Note: 1, pneumatically operated, must change completely push the handle to move (points) where indicated, to refrain from the handle in the division of unknown status, otherwise, it will damage the internal parts. 2, non-beating or striking handle. V. manually with pneumatic discharge valve installation should note the following: 1, to keep the valve to seal ring sealing surface dirt, sand .. 2. Check the packing is sealed to the piston, are forbidden entry, to be under the guidance of technical personnel. 3, when the cylinder is removed a long time, all machined surfaces should be coated with anti-rust oil, intake and exhaust ports should be added to the dust clogging. Sixth, after manually with pneumatic discharge valve installation of piping pressure test valve must be fully open repair: 1, the installation should be carefully checked before use is consistent with the performance of the valve. 2. Check all parts are tightened. 3, should ensure that the work on maintenance and easy to replace. Seven manually with pneumatic discharge valve in the course should be checked regularly: 1. Check the valve stem and packing wear, in order to avoid leaks. 2, regular pneumatic head surface dust and maintenance.
