Heating valve closed due to lax reasons:
(1) sealing surface damage or mild corrosion.
(2) improper operation, closing the sealing surface contact is not good.
(3) Stem bending, upper and lower sealing surface is not center.
(4) impurities plug spool.
Heating valve closed lax solution:
(1) adhere to the valve into the water pressure test, including the strength test and tightness test, test the valve should be carefully examined, analyze the reasons, gently open and close a few times before making a test, is still closed, To disassemble the check, first check the valve stem condition, check the sealing surface of the valve plate, and grind if necessary. After inspection and repair, grinding and re-test pressure, you can overcome the non-flawed shut down to allow continued use, belongs to the valve manufacturing plant product quality problems should be returned replacement.
(2) Valve sealing surface defects, including scars, knives, crushing, unevenness, dents, etc., when the depth is less than 0.05mm, available grinding to eliminate; depth greater than 0.05mm, should be processed in the lathe, and then Grinding again, does not allow the use of file or sandpaper grinding and other methods of repair.

General methods are mostly used for comfort. A few patterns, color blocks or texture effects of general points, lines and surfaces are used to form a picture of iron cans. The picture is concise, eye-catching, and has a sense of style. The painting method of graphic planning of objects is intuitive and has a strong interest in appreciation.
