Technical requirements for installation
1 hot air valve stem perpendicular to the ground only installation, commissioning should be perpendicular to the ground in the stem under the condition of;
2 hot air valve ventilation and cooling water inlet and direction must be consistent with the icon to install the signal. Install the valve when the arrow points toward the air main pipe; the hot blast valve used for combustion flue valve valve, when the arrow points toward the hot stove; hot blast valve used to back off air valve when the arrow points toward the air main pipe; the hot blast valve used for mixing air cut off valve when the arrow should be back to the hot air pipe (installation of hot air valve as the valve only refer to the nameplate name is "hot blast valve", has been identified as the valve nameplate name name, the wind direction arrow is the direction of medium).
3 before debugging applications cotton valve body, valve plate sealing surface wipe clean, so that the sealing surface is scratched. Before the operation, all to the point of lubricating oil, the floating seal parts of the graphite powder injection or grease;
After the installation of 4 check valve body, valve cover bolt, valve stem seals and other parts, so as to ensure no leakage and the valve plate whereabouts smooth. Manual low-speed valve confirmation runs normally start and then start the test run;
5, the valve pipeline installation for the whole installation (not including transmission). Install the lifting point as the lug on body (in the round flange 4, a valve cover lug is strictly prohibited for integral lifting), valves are integrally mounted after the transmission device installed in the valve;
6 valve pipe flange between the application of ceramic metal gasket coated with high-temperature sealant for sealing, prevent leakage;
7 when the valve is opened, the lower valve plate should be higher than the valve channel along the 100mm (test methods: the valve plate to ascend to the upper limit and then drop 50mm open position the valve plate). Valve cooling water flow, water temperature is below 40 ℃;
8 valve factory before installation, the transmission rack and a valve body packed separately stored, then the overall installation site. When installed according to the installation position of the interface with the transmission valve body connected tightly, the position of the proximity switches installation adjustment fastening. When commissioning the valve, after the power should be started manually. (Note: the hydraulic valve is installed, the opening and closing state, the piston of the cylinder valve free stroke adjustment on both sides, and then fix the travel switch. Rack and pinion hydraulic valve should be based on the valve plate stroke limit position of cylinder piston position, and then hang chain). Operation should be smooth not have collision and impact card lag phenomenon.
The use of valve repair and maintenance
Sealing performance of the 1 examined weekly valve is closed, the touch, hearing feeling determinant Valves sealing effect, found problems in a timely manner to report processing;
Leakage of 2 classes before the classes after checking the cooling water temperature, water pressure and everywhere, find out problems in a timely manner;
The 3 opening and closing the valve should pay attention to observe the running situation, found problems in a timely manner;
4 regular weekly two filling lubricating oil, grease, prevent oil starvation burn damage to moving parts;
5 prohibited for use in cooling water shortage and water conditions;
6 regular inspection and cleaning valve sediments, abnormal timely treatment;
The 7 electric device of electric valve electric device use please read instructions provided by random.
