| description | A flow channel in the horizontal direction is arranged in a valve body, a gate plate is installed in the valve body, and the gate plate is matched with a valve seat on the flow channel of the valve body in a sealing mode. A valve rod is mounted at the upper end of the flashboard and is driven by an executing mechanism to do lifting motion to control the flashboard to open and close the valve; the valve cover is connected with the valve body, the valve cover and the valve rod are sealed through a packing mechanism, Ni65 alloy layers with the thickness of 1.6 mm are sprayed and welded on the sealing surfaces on the two sides of the gate plate, and Ni65 alloy layers with the thickness of 0.5 mm are sprayed and welded on the other overflowing surfaces of the gate plate; a Ni60 alloy layer with the thickness of 1.6 mm is sprayed and welded at the sealing contact position of the valve seat and the gate plate, and a Ni60 alloy layer with the thickness of 0.5 mm is sprayed and welded at the other overflowing part of |
