1. Hot air valve stem perpendicular to the ground only installation, commissioning should be perpendicular to the ground in the stem under the conditions;
2. Hot air valve ventilation, cooling water entering and leaving the direction of the direction and must comply with the icon to install the hint. When the hot air valve installed wind direction arrows should point to the hot head of Road; hot air valve used to burn valves, flue gas valve, wind direction arrows should point to the stove; hot air valve air valve used to turn the clock back when you break wind direction arrows should point to hot head Road; hot air valve used be mixed with air shut-off valve should be headed in opposite directions when the wind direction arrows in charge of Road hot air (hot air valve for the valve installation of the other name is still confined to plate "hot air valve", the nameplate has made it clear the name of the name of the above-mentioned valve, its the wind direction arrows, compared with medium flows).
3. Debugging cotton yarn will be before the application of the valve body, valve plate sealing surface wipe clean, so that the sealing surface is scratched. Pre-operational, all to the point of lubricating oil, the floating seal parts of graphite powder injection, or grease;
4. Installed check valve, valve cap, valve stem seals and other parts of the bolts fastening, so as to guarantee not to leak out and valve plate whereabouts smooth. Slow start valves manually to confirm body is operating normally and then start the test run;
5, Valves for pipeline installation for the whole installation (excluding transmission). Install lifting point on the lug body (in the circular flange at 4, valve cover for the whole lifting lug is strictly prohibited), the valve and then the whole installation will be installed in the valve gear on;
6. Valve pipe, flange, metal gasket between the application of ceramic coating high-temperature sealant plus sealed to eliminate air leakage;
7. Valve is turned on, the lower valve plate should be higher than 100mm above the valve along the channel (debugging method: the valve plate to the upper limit and then raise the whereabouts of 50mm as a valve plate open position). Valve cooling water to flow, the water temperature is below 40 ℃;
8. Valves factory pre-installation, transmission valve body frame and packaged separately stored, on-site and then the whole installation. Installed according to installation of the position will interface with the transmission valve body to connect fastened near the switch location on-site installation after adjustment fastening. Valve commissioning should start the first hand after the driving force. (Note: Hydraulic valve installed in the valve open and close state, so that both sides have a spare fuel tank of the piston stroke, adjust the limit switch and then fixed. Rack and pinion hydraulic transmission valve shall be under the valve plate stroke limit position adjustment cylinder piston position, and then hanging chain). Operation should be stable and should not have collision and the impact of catching phenomenon.
Valve repair and maintenance of the use of
1. A week to once the valve closed when the sealing performance, namely, touch, ears feel to determine the valve sealing effect, identify problems timely report processing;
2. Ban after the pre-class checks the cooling water temperature, pressure, and everywhere outside the leakage problems are discovered immediately removed;
3. To open the valve should be closed to observe the smooth operation conditions, identify problems and timely treatment;
4. On a regular basis twice a week, filling of lubricating oil, grease, to prevent the functioning of parts short of oil burn damage; wear-resistant electrode
5. Is strictly prohibited without water in the cooling water shortage, and under the conditions of use;
6. Periodic inspection and cleaning valve deposits, abnormal timely manner;
7. Electric valve electric device instructions please read the instructions supplied with electric devices.
Other
1. Valve storage and transportation should be maintained placed in the bottom of the valve sealing surface, and the wind vane arrow facing up (known as flue plate valve, back off air valve, mixing air shut-off valve, then the vane arrow down) and valves rod firmly fixed in the closed position to prevent vibration collision damage sealing surface;
2. Drive installed in the factory installation after passing the custody of apart shipped separately.
