FLUSH APPARATUS FOR WATERING SYSTEMS

摘要

A flushing system for poultry watering systems is provided which includes a by pass of the upstream pressure regulator, self sealing caps for the stand pipes and an automatic flush valve at the end of the supply line. A shut-off valve in the by pass is provided which is actuatable manually or automatically in response to a timer, environmental sensor or water condition sensor. The automatic flush valve opens a response to a predetermined pressure level and connects the supply line to a drain hose. The self sealing caps prevent leakage out of the standpipes and are especially formed to prevent blow outs of the seal. Where multiple pressure regulators are used in the supply line, additional automatic flush valves can be positioned in a by pass line around those regulators.
