Quick release system for a quick and easy changeover of WEH® gas filling connectors to another type
When changing over to gas cylinders having different cylinder valves, the filling hose has to be disconnected from the filling connector. The quick release coupling has solved this problem, as each WEH® connector can use the TK350 quick coupling and the corresponding TN350 quick coupling nipple fitted to the filling hose. The quick release system is used for quick changes of WEH® connectors, either for repair or for a changeover to another type of connector. For example a change from residual pressure to non-residual pressure connectors is easily achieved. No additional swivel joint is necessary with the TK350-TN350. The quick release system consists of the quick coupling type TK350 (without shut-off valve) for direct connection to the WEH® Connector types TW54, TW57 and TW67 and a quick coupling nipple type TN350 (without shut-off valve) for connection to the filling hose. The TK350 coupling is hand-tightened directly to the WEH® Connector and the TN350 nipple directly to the filling hose. When changing between different cylinder valves merely disconnect coupling and nipple by unlocking the bayonet lock and pulling back the sliding sleeve of the TK350. The TN350 nipple remains mounted to the filling hose and is connected to another WEH® Connector also equipped with a type TK350 quick release coupling. This ensures a quick and easy changeover of illing connectors. The TK350 quick coupling is equipped with a red indicator ring which is not visible when correctly connected and a bayonet lock for additonal safety against accidental disconnection.
