<p>Appts. for extracting an explosive mixture of gasses from a painting or drying tunnel injects an inert gas into the gas filler zone. In the discharge opening of the inert gas container is a bistable distributor valve, to block or permit the discharge. A line also passes through connectors to a control system to maintain pressure within safe levels. The distributor valve has a pressure limiter set to a required value, and a non return valve. It also has a membrane which can be inflated towards the outside, communicating with the non return valve. Two interchangeable gas cylinders can be mounted on a common carriage.</p> |
