Problems solved by technology

[0003] In the above-mentioned prior art valve structure, the valve stem as a movable part passes through the through hole provided on the valve cover, and the water in the valve body may leak out from the junction of the through hole and the valve stem. Now solve the leakage The solution to the problem is to fill the gap between the valve stem and the valve cover with ordinary packing. Under the influence of the long-term movement of the valve stem, the packing will move and leave the position due to insufficient strength, and cannot self-adjust and recover, so it cannot prevent seepage. Leakage effect, requiring frequent replacement and maintenance

Abstract

The invention relates to a double-loop sealing ring, characterized in that it is the circular ring and grooves are set in the inside and outside of the ring; O-shaped rubber rings are embedded in the grooves respectively. The invention also provides a valve with mentioned double loop sealing ring, comprising valve and valve cover fixed with valve body. Valve bar extends into valve body through the hole opened on the valve cover. It is characterized in that double loop sealing ring is set on the valve bar; the outer O-shaped rubber ring is set against valve body and the inner O-shaped rubber ring is set against valve bar. The invention provides safe and reliable sealing ring for the location of valve bar in valve so as to improve the service life of valve and decrease the maintaining cost generated by frequently repairing and changing.

Description

technical field [0001] The invention relates to an improvement of water heating equipment, in particular to a double-ring sealing ring and a valve using the double-ring sealing ring. Background technique [0002] A general valve, whether it is a manual opening and closing valve or a delay flushing valve, the basic structure of the opening and closing includes a cavity valve body with a water inlet and a water outlet, an opening is set on the valve body, and a valve cover is fixed at the opening position. The valve stem enters the valve body through the through hole provided on the valve cover. The valve stem can be the valve stem of a manually opened and closed valve, that is, the upper end of the valve stem is connected to the handwheel, and the thread on the valve stem cooperates with the stem nut fixed on the valve. The disc opens and closes the water channel in the valve body to open and close the valve. The valve stem can also be the valve stem of the delay flushing v...
