Abstract
PURPOSE: To avert the formation of oxide in the inserts and produce the valve of good sealing function by coating the material which produces reducing gas by the effect of heat on the sheet members made of carbon steel, installing these in the mold for valve box and pouring molten cast iron.
CONSTITUTION: The material which produces reducing material by the effect of heat, such as epoxy-base resin, is coated on the outside surface of a sheet member 2 made of carbon steel and is fixed in a mold 1 for valve box. Molten cast iron is poured into this mold 1 to insert the sheet members 2, 2 in the valve box 3 made of cast iron. Thence, corrosion-resistant metal of stainless steel is build-up-welded on the inside peripheral surface of the sheet members 2, 2 to form a metal sheet 5. A necessary valve mechanism is assembled to this valve box 3. In casting this valve box 3, reducing gas evolves from the material coated on the sheet members 2, by which the formation of oxide films and welding defects are averated. This method makes it possible to obtain the inexpensive valve without impairing its intrinsic sealing function.
