H44HSwing Check ValveAdopting internal rocker arm rotary opening structure, all opening and closing parts of the valve are installed inside the valve body, without penetrating the valve body, except for the middle flange part with sealing gasket and sealing ring, there is no external leakage point in the whole. Widely used in chemical industry, metallurgy, pharmaceuticals and other fields.
工作原理
H44H rotary check valve adopts internal rocker arm rotary structure, the valve flap rotates around the rotary axis, the valve flap opens under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure of the inlet side is lower than that of the outlet side, the valve flap closes automatically under the effect of fluid pressure difference, gravity and other factors to prevent backflow of fluids.
