Pneumatic pneumatic - valve Pneumatic valve body and bonnet leakage causes and solutions

the reason. Cast iron casting quality is not high, pneumatic valve body and valve cover on the body has the defects such as sand holes, loose organization and slag; 。 Days freezing crack; 。 Bad welding, there is a slag, no welding, stress crack defects such as; 。 Pneumatic valves are heavy cast iron after a crash damage. The prevention and solution. Improve the quality of casting, before installation in accordance with the provisions of strength test; 。 To temperature under ° and ° pneumatic valve, should be insulated or hot, stop using the pneumatic valves should be ruled out water; 。 Pneumatic valve body and valve cover of welding the weld, shall be carried out according to relevant welding procedures, also should carry on the inspection and after welding strength test; 。 Pneumatic valves on push heavy objects, do not allow the hammer impact non-metallic pneumatic valve, cast iron and the installation of large diameter pneumatic valve should have support.
