Freeze Safe Valve
Freeze Safe Valve
US Patent:
4766923, Aug 30, 1988
Filed:
Nov 20, 1986
Appl. No.:
6/933048
Inventors:
Bernarr G. Roper - Provo UT
International Classification:
F16K 1736
US Classification:
137 15
Abstract:
A freeze safe valve has a valve body, a valve gate, a washer, a fastener having an interior channel, and a plug placed in the channel of the fastener. With fluid pressure in the normal downstream direction, the plug will be held in place, and the valve will function as a standard valve. However, when net pressure exists in the upstream direction at a certain predetermined level due to, for example, the formation of ice on the downstream side of the valve, the plug will become dislodged so that fluid may flow back to the upstream side. This will alleviate the pressure on the downstream side and ideally will preclude breakage of the downstream pipe or the valve itself.
