Speaking of American standard gate Industrial Valves this noun, a lot of people said not too clear, but talked about ram set people are very familiar with, they both are one and the same. American standard gate valve it is a kind of used in oil, water and electricity, chemical industry and other fields in the realization of pipeline flow or cutting tools. Compared with general gate valve, its sealing is stronger, switch more relaxed, seal gate valves of the elastic base seat is more compensation effect, effectively makes up the defect of the general valve sealing and rust. Start first, American standard valve parts is ram, ram movement direction and perpendicular to the direction of fluid flow in the piping, therefore the mark gate in the practical work often play is turned on and off the effect of fluid, and cannot be applied to adjust and throttling effect. Second, in the American standard gate valve is a pressure relief hole, in the use of the usual process to avoid the jams. A pressure relief hole is designed to prevent cavities of abnormal pressure in the body. When American standard gate valve in the closed its cavity exists in the body of low temperature medium, but with the passage of time, the media will continue to absorb heat at low temperature and gasification phenomena will happen, and after gasification medium volume swells and generate larger pressure, after stress accumulation will damage the valve and dangerous. And the effect of pressure relief hole is will this extra pressure discharge, the cavity pressure return to low temperature condition. Although American standard gate Industrial Valves installation is simple, using range is wide, the pipe dielectric fluid resistance small, not disturbing, not limited to, and open and shut easily, but due to large dimension, open needs certain space, and prone to erosion between the sealing surface, after the failure of maintenance trouble, the people in the process of using or caution.
