Abstract

The invention discloses a valve base compression mould of a chlorine gas valve and relates to the technical field of a valve base compression mould tools. The valve base compression mould provided by the invention comprises a valve base basal body and an annular external mould, wherein the lower surface of the annular external mould is provided with steps, and the valve base basal body is matched with the annular external mould and arrange below the annular external mould through the steps; a positioning mould core is arranged in the annular external mould and is arranged above the valve base basal body, and the positioning mould core and the valve base basal body are matched through a rabbet; and a stressing mould pressing sleeve is arranged between the positioning mould core and the annular external mould in a sliding manner, and an annular groove the width of the groove port of which is concurrent with the thickness of the stressing mould pressing sleeve is arranged on the valve base basal body corresponding to the lower end of the stressing mould pressing sleeve. A sealing surface (tetrafluoro ethylene resin part) of the valve base, which is formed by the valve base compression mould through mould pressing and sintering is combined with the valve base basal body firmly without getting loose of falling off, and the sealing surface of the valve base and the valve base basal body are firmly combined together and are corrosion-resistant.

Description

technical field [0001] The invention relates to the technical field of valve seat compression molds. Background technique [0002] At present, most domestic manufacturers use polytetrafluoroethylene pipes to heat and mold the valve seat when they produce this product. The combination is not strong, loose, or even falls off, and it is easy to leak. Contents of the invention [0003] The object of the present invention is to provide a chlorine valve seat compression mold which is firmly combined with the valve seat base, does not loosen, does not fall off, and is corrosion-resistant. [0004] The present invention comprises a valve seat base and an annular outer mold, steps are provided on the lower surface of the annular outer mold; the valve seat base is arranged under the annular outer mold through steps; within the annular outer mold, on the valve seat A positioning mold core is arranged above the base, and the positioning mold core and the valve seat base are arranged ...
