Hot air pneumatic valve installation and maintenance of the 2)

installation requirements. Hot air valve pneumatic valve stem vertical installation, only the debugging should be perpendicular to the ground under the condition of dry;
。 Hot air pneumatic valve, air and water must observe in the direction of the icon to install signal direction. As the hot air pneumatic valve installation direction arrow should point to the heat pipe; Pneumatic valve, combustion flue should wind direction arrow pointing in the direction of hot blast stove when hot air pneumatic valve pneumatic valve; Hot air direction arrow should point to pneumatic butterfly valve back pneumatic valve tube; Hot air pneumatic valve and air should blend to shut down the wind direction arrow head channel hot air ( About other pneumatic valve installation of hot air valve is still limited in the name plate 'thermopneumatic valve', these pneumatic valve, pneumatic valve nameplate, have made it clear that the name of naming, by contrast, the medium flow direction arrow) 。
。 Debugging before the application of cotton yarn pneumatic valve, pneumatic valve plate seal face to wipe clean, make the sealing surface scratches. Before running, lubricants supplier, graphite powder injection or floating oil seal;
。 Install check pneumatic valve, pneumatic valve cover, pneumatic valve stem seal and tighten, to make sure that no air leakage, pneumatic valve plate fall parts such as bolts. Slow start pneumatic valve manually confirm the agency operating normally, and then start commissioning;
, for the whole pipe installation ( Do not include transport) Installation of pneumatic valve. Ear lifting point is installed on the body ( In the first round of the flange, pneumatic valve bonnet lugs of integral is prohibited) , pneumatic valve, and then install the entire installation in pneumatic valve device;
。 Pneumatic valve tube heat sealing glue sealing between metal ceramic coatings, prevent air application plus flange gasket leaking;
。 Pneumatic valve opening on the bottom of the pneumatic valve plate edge should be a name than the pneumatic valve of the channel (mm high Debugging methods: upper limit of pneumatic valve plate, and then rose to pneumatic valve plate for open position whereabouts 五十〇 mm) 。 Pneumatic valve of cooling water flow rate, water temperature is less than ℃;
。 Before install pneumatic valve factory pneumatic valve driver body frame and packaging stored separately, then the entire field installation. By installing pneumatic valve installation and transmission interface position nervous, position close to the scene to install tighten. When debugging pneumatic valve, after turning on the power supply, should be started manually. （ Note: hydraulic pneumatic valve installed in the state of the pneumatic valves open and close, make both of us have a fixed limit, after the standby switch to adjust the cylinder piston stroke, gear rack type hydraulic pneumatic valve travel restrictions should be in the position of the pneumatic valve plate adjustment cylinder piston. Position, then the chain hoist) 。 May not be a smooth operation and the impact of collision and cable wiring. Pneumatic valve repair and maintenance to use the

. Check, pneumatic valve sealing performance is closed, the contact of one week, feel the ear determine pneumatic valve seal, the report found that deal with the problem in a timely manner;
。 Before class in the class, check the temperature of the cooling water, the pressure and leak around the outside, found the problem and remove;
。 That should be paid attention to close the pneumatic valve operation stability, found the problem in a timely manner;
。 Twice a week filling of lubricating oil, grease, moving parts, to prevent hunger burned damage;
。 Strictly prohibited without water cooling water shortages and conditions of use;
。 Regular inspection and cleaning of pneumatic valve deposits, processing if it is abnormal;
。 Electropneumatic valve electric actuator, electric actuator read attached instructions.

other. Valve, storage and transportation should be placed at the bottom, keep the pneumatic valve sealing surface, and an indicator arrow up ( The flue gas dynamic valve plate, back to the butterfly pneumatic valve, when mixed with air by the pneumatic valve, blade down arrow) And pneumatic valve rod firmly fixed in the closed position, in case of collision damage to seal surface vibration;
。 Qualified transmission device, the only manufacturer in open the custody of the goods.
