Abstract

A stopwater device comprises of a first grip ring and a second grip ring closing each other and clamping at the outside of flange. The grip ring is composed of a concave i.e. U type semi-torus, inside which is equipped with a cavity for injecting the stopwater solution. At least one injection port of stopwater solution, which is equipped with a valve body including a valve seat and a valve stem, is mounted at the outside of the grip ring. Because the filling gun is inserted into the axial hole on each valve seat, and the stopwater solution is injected into the cavity in the grip ring through the valve body, the leakage of the flange can be stopped rapidly without removal of the flange, and achieve effects of the rapid stopwater.
