PACKING STRUCTURE OF PRESSURE RING FOR WATER SERVICE

摘要

A detachable packing for a joint of pipeline supply is provided to prevent water from leaking remarkably by forming a plurality of protrusions on the outer periphery of the packing. A detachable packing(20) for a joint of pipeline supply comprises an inclined surface(22), a support protrusion(23), a recess(24). The inclined surface contacts with an inclined plane at a support portion of the joint. The support protrusions are formed on the inclined outer periphery guided to a packing placing portion. The recess is formed on the inner diameter of the packing to provide elastic force when the packing is pressed.
