Abstract: PURPOSE: Structure and a device for packing are provided to improve chemical resistance and stability by combining the hetero-members of chemical resistant materials and restoring materials. CONSTITUTION: A valve has a valve main body having a flowing path and a ring-shaped valve opening/closing plate. A ring-shaped first member(110) seals a gap between the valve opening/closing plates by installing in the inner circumference of the main body and has a recessed groove(114). A ring-shaped second member(120a) is fixed in the girth of the first member and closes the recessed groove to form a sealed space portion. An elastic portion integrates the first/second members by compressively filling an elastic material into the sealed space portion. Thereby, a packing member(120) having chemical resistance, corrosion resistance and stability are obtained. The packing member is separately formed by at least two semicircles. Inlets(122a,122b) are formed in each separating bodies to inject the elastic material into the closed space portion.
