Import ventilation butterfly pneumatic valve installation operation specification is introduced

electric pneumatic valve USES the line type ventilation butterfly disc plate and short structure is a new type of structure design and manufacture of the steel plate welding, compact structure, light weight, easy installation, small flow resistance, big circulation, avoid the influence of high temperature expansion, convenient operation. The body without connecting rod, bolts, etc. , reliable operation, long service life. Can be installed in a transfer, not affected by the medium flow direction.
ventilation butterfly electric pneumatic valve is mainly used in metallurgy, chemical industry, building materials, ventilation, environmental protection engineering in power plant, glass and other industries of dust in the cold or hot gas pipeline, the gas medium flow adjusting or cutting device.
the butterfly pneumatic valve system adopts central type disc plate and short structure, a new type of structure design and manufacture of the steel plate welding, compact structure, light weight, easy installation, small flow resistance, big circulation, avoid the influence of high temperature expansion, convenient operation. The body without connecting rod, bolts, etc. , reliable operation, long service life. Can be installed in a transfer, not affected by the medium flow direction.
electric pneumatic valve should save dry ventilated indoor ventilation butterfly, on both ends of the channel must be blocked. Long-term storage of electropneumatic valve should be checked regularly, remove dirt, and rust-proof oil coating on the surface of the processing. After installation, should check regularly, main inspection items: sealing surface wear. Pneumatic valve stem and abrasion of trapezoidal thread of pneumatic stem nut. Packing is outdated failure, if any, should be replaced in a timely manner. Electric pneumatic valve repair after assembly, should carry on the sealing performance test.
ready to operate pneumatic valve before the operation, should read the instructions carefully. Before operation must clear the flow of gas, we should pay attention to check the pneumatic valves open and close. Check the electric pneumatic valve appearance, see the electric pneumatic valve whether be affected with damp be affected with damp, if there be affected with damp be affected with damp be dry processing. If it is found that there are other problems should be handled in a timely manner and shall not take fault operation.
to disable months above the electric device, should check before starting clutch, confirm the handle after the manual position, check the insulation of the motor, steering and electrical wiring. Electric pneumatic valve operating considerations starts, if it is confirmed the clutch handle in the corresponding position in the control room control electric pneumatic valve, beat switch REMOTE location, and then through the SCADA system control electric pneumatic valve switch.
if the manual control, the switch position in LOCAL, on-site operation switch of electric pneumatic valve, electric pneumatic valve in place or close in place it will automatically stop working, and finally beat operating switch to the middle position. Using field operating pneumatic valve, pneumatic valves open and close should be monitored directives and running status of pneumatic valve stem, pneumatic valves open and close degree to meet the requirements.
using site operation all close the pneumatic valve, pneumatic valve in place before, should stop electric pneumatic valve, switch to micro pneumatic valve in position. Setting after a stroke and super torque controller in pneumatic valve, fully open or close the pneumatic valve for the first time, the monitoring should be paid attention to the control of the stroke, such as pneumatic valve switch to the position without stop, should be manual emergency stop immediately. In the process of open, her breath valve, the error is found in the signal lamp instructions, pneumatic valve have abnormal sound, should stop check in time.
the electropneumatic valve should be closed after a successful operation of the power. Multiple operation of pneumatic valve at the same time, should pay attention to the sequence of operation, and meet the requirements of production process. Open a vent valve near a large pneumatic valves, if on both ends of the pressure difference is bigger, should first open the ventilation pressure regulating valve, pneumatic valve to open: main pneumatic valve opens, shall be immediately shut down beside the vent valve. Transceiver pigging ball, ) When it passed the pneumatic ball valve must be fully open. Pneumatic operating pneumatic ball valve, gate valve, globe pneumatic valve, pneumatic butterfly valve can only be fully open or close, it is strictly prohibited to adjust. Operating brake pneumatic valve, globe pneumatic valve and tablet in the process of the pneumatic valve, when closed or open to the top dead center or bottom dead center, should be turning circle / ~.
