| 摘要 |
<p>It comprises, in at least one of the pneumatic lines of the coating system, a valve (2) in the form of a non-return valve which, in the flow duct (6), has a valve element (4) which is urged in the closing direction, counter to the through-flow direction (14) and against a valve seat (10) by a spring element (8). Also provided in the flow duct (6) of the valve is a blocking element (16) which is made of a material which can be dissolved easily and rapidly by liquid and holds the valve element in the open position despite the action of the spring element (8) until it is dissolved by a liquid. As a result, the valve is open in both through-flow directions during normal operation, contrary to the action of a non-return valve. Only when a liquid enters is the blocking element (16) dissolved by the liquid and the valve (2) operates like a normal non-return valve. <IMAGE></p> |
