Nuclear Grade Wafer Butterfly Valve
Introduction:
Nuclear-grade butterfly valves usually have three structures, coaxial direct-connected rubber-lined butterfly valve, eccentric metal-sealed butterfly valve and double-acting metal-sealed butterfly valve.
The nuclear grade butterfly valve can be used in the cooling water system of the million-kilowatt pressurized water reactor nuclear power plant.
Features:
(1) Simple structure, small size, short structure length, small volume and light weight.
(2) When fully open, the effective flow area of the valve seat channel is larger, and the fluid resistance is smaller.
(3) The opening and closing are convenient and fast, and the adjustment performance is good.
(4) The opening and closing torque is relatively small, because the butterfly plates on both sides of the rotating shaft are basically equally affected by the medium, and the direction of the torque generated is opposite, so the opening and closing is relatively labor-saving.
(5) The sealing surface material is generally rubber and plastic, so the low-pressure sealing performance is good.
