valve for protecting drain system
(OP)
Does anyone know of a simple valve that is normally open to allow water to flow (like a drain) but closes when there is a sudden increase of pressure.

A conventional pressure reducing valve (regulator) is wide-open until the downstream pressure exceeds its setpoint, then it closes. A "good" regulator has a very narrow proportional band.

If you have to protect the downstream piping from overpressure then use two regulators in series (monitor setup).
My suggestion is based on the assumption that the drain line is a smaller diameter like 2", 3" or smaller.
