1. Ordinary hot air valve installation and use of technical requirements 1. Hot air valve stem can only be installed vertically on the ground, the commissioning should be carried out under the vertical stem conditions; 2. Hot air valve ventilation direction and the direction of cooling water must comply with the installation diagram Targeted. Hot air valve is used as a combustion valve, flue valve when the wind direction arrow should point to the hot air stove; hot air valve used as a reverse flow off when the wind arrow should point to the main hot air pipe; hot air valve The wind direction arrow should be turned back to the main hot air pipe when the mixing air cut-off valve is used. (When the hot-air valve is used as the above-mentioned other valve installation method, only the nameplate is still hot-air valve and the nameplate is clearly the above valve name, Then the media flow). 3 before commissioning cotton yarn body, valve plate sealing surface wipe clean, so as not to be sealed surface is scratched. Before operation, each oil point plus lubricant, floating seal parts scatter graphite powder or grease; 4. Check the valve body, bonnet, stem seal and other parts of the bolt fastening to ensure air leakage and valve Plate fell smoothly. Manual low-speed start the valve to confirm the normal operation of institutions and then start the trial operation; 5. The valve pipe installation as a whole installation (excluding transmission). Installation Lifting point for the valve body hanging lugs (located at the round flange at 4, cover lugs is strictly prohibited for the overall lifting), the valve installed after the transmission installed on the valve; 6. Valve pipe flange Application of ceramic metal gasket coated with high temperature sealant to seal, to prevent air leakage; 7. When the valve is opened, the lower valve plate should be higher than the valve along the 100mm above (debugging method: the valve plate to the upper limit and then drop 50mm Valve plate open position). Valve cooling water to be unimpeded, the water temperature is below 40 ℃; 8. Valve factory installation, the drive frame and valve body separately packaged storage, the overall site installation. Install the valve according to the position of the interface to install the valve body and the drive connected to the fastening, close to the switch position on-site installation and adjustment of the fastening. Valve test run, you should manually start after the power. (Note: When the hydraulic transmission valve is installed, open and close the valve so that both sides of the cylinder piston has a free stroke, adjust and then fixed travel switch gear rack and pinion hydraulic transmission valve should be based on the valve plate stroke limit position adjustment cylinder piston Location, then hang the chain). Smooth operation should not be collision and impact of the phenomenon of arrest. Valve maintenance and maintenance 1. Weekly check the sealing performance when the valve is closed, that is, touch, feel the sound to determine the valve sealing effect, identify problems reported in a timely manner; 2. After class to check the cooling water temperature, water Pressure and leaks everywhere, and identify problems promptly ruled out; 3. Open the valve should be closed to observe the smooth operation of the situation and found that problems in a timely manner; 4. Weekly regular filling of lubricants, grease, to prevent running parts missing Oil burn damage; 5. Do not use less than the cooling water and water conditions; 6. Regularly check and clean the valve deposits and found abnormal timely manner; 7. Electric valve electric device instructions for use, please read the supplied electric device manual . Other 1. Valve storage and transportation should be kept below the sealing surface of the valve, and the wind vane arrow up (nameplate name for the flue valve, return valve, mixed wind shut-off valve, the vane arrow down) and Valve stem firmly fixed in the closed position to prevent vibration damage to the sealing surface; 2 transmission installation and commissioning in the factory opened after a separate custody shipping.
