Installation and use of technical requirements 1. Hot air valve can only be installed on the vertical stem of the valve used, 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 of the schematic direction. 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 cutoff 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 has been clearly defined as 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 valve to confirm the normal operation of institutions and then start the test run; 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 have free travel, 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 repair 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 time; 2. After the class to check the cooling water temperature, water pressure and Leaks throughout the situation, 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 lack of oil burn Damage; 5. Do not use less than the cooling water and water conditions; 6. Regularly check and clean the valve deposits, abnormal and timely treatment; 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 vane arrow up (nameplate flue valve, return valve, mixed wind cut off the valve, the vane arrow down) and the 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.
1.Used for high precision machining ,no clamping nut required,avoiding the interference of workpiece during maching .
2.The design of collet pull,stronge rigidity,higher stability.
3.-196℃ long cryogenic treatment ,reduce residual stress,wear resistance improved significantly .
3.Super long stereotypes heat can effectively remove the residual stress during the grinding processing .
4.Balance G2.5/G6.3 for choose .And each handle is equippen with a spanner.
