Bottom valve performance and application
Bottom valve performance and application: The bottom valve is an energy-saving valve, usually installed in the bottom of the pump underwater suction pipe. Restrict the pump tube liquid back to the water, played only out of the function. Influent and stiffeners, played a difficult to plug, mainly used in the pumping pipe. Waterway and the role of support. Caliber single valve, double valve, multi-valve type. Flanged connections and threaded connections. Valves, valves, bonnets, bushings, seals and other components, as shown in the picture below Water from the valve cover into the body. Under the pressure of the fluid, the valve open the water, Pressure will quickly close the valve, the liquid will not be back to the water, played a smooth pumping and water loss. 1, in order to prevent the media countercurrent, in the equipment, installation and piping should be installed on the check valve; 2 , Check valve is generally suitable for cleaning media, should not be used for medium containing solid particles and larger viscosity; 3, generally in the nominal pass through the 50mm level pipe should be used vertical lifting check valve; lift performance specifications nominal Pressure: PN0.25MPa nominal pass Diameter: DN15 ~ DN350 Applicable medium: water, oil, and non-corrosive media Executive Standard: Q / 12 NJ3583-2001 Test Standards: GB / T13927-1992 This article Keywords:
