YK43H valve

YK43H valve valve by regulating the import reduced pressure to a desired outlet pressure, and rely on the energy of the medium itself, so that automatically maintain a stable outlet pressure valve. From the point of view of fluid mechanics, the throttle valve is a local resistance to change the original, that is by changing the throttle area, so changing the flow rate and fluid kinetic energy, resulting different pressure loss, so as to achieve the purpose of the valve, then rely on regulatory control and regulation system is the valve spring force of pressure fluctuations in equilibrium, so that the valve pressure was kept constant within a certain error range. Valves for fluid control systems, from simple to very complex cut-off valve automation system all valves, which are more varieties and specifications, the valve can be used to control air, water, steam, corrosive media, mud , oil, liquid metals and radioactive media and other types of fluid flow. Valve according to the material can be divided into cast iron valves, cast steel valves, ductile iron valves, stainless steel valves (201,304,316, etc.), chromium-molybdenum steel valve, chromium molybdenum vanadium steel valves, dual-phase steel valves, valves and other non-standard custom materials. Valve Note: 1, in order to operate and easy to maintain, change the valve is generally upright in horizontal pipelines. 2, must be strictly consistent with the direction of fluid flow in the direction of the arrow before valve body mounting. If the water dirty, there are impurities in the valve must be installed upstream of the filter. 3, in order to prevent over-pressure valve after the pressure should be less than 4m away from the valve outlet installed at a valve. 4, play a non-return valve in the pipe in order to prevent water hammer damage, you can also install a small expansion tank. Prevent damage to pipes and valves, filters must be installed before the inlet valve, and the expansion tank must be installed in the valve outlet pipe. 5. If the valve needs to be installed in the hot water system, you must install a check valve between the valve and the expansion tank. This is to allow the expansion tank absorb the increase due to thermal expansion of the volume of water, but also can prevent the effects of hot water reflux or pressure fluctuations on the valve to ensure long-term work valve.
