Abstract:
Valve for connecting a flow module to a flow line, said flow module having inlet and outlet openings and a flow channel disposed to admit a liquid flow there-between, the valve comprisinga. a first body defining first and second openings and a flow channel passing there-through, the flow channel extending in fluid communication between the first and second openings, first and second openings being positionable in fluid communication with the inlet and outlet openings, respectively, of the flow module, and b. a second body, incorporating or adapted to accommodate the flow module, the first and second body being slidably arranged in such way that the module inlet and outlet openings sealingly connects in fluid communication with the first and second openings, respectively, when the first and second bodies are relatively displaced in a module connecting position, and the second body provides for liquid flow communication between openings when the first and second bodies are relatively displaced in a module dis-connecting position, wherein liquid flow communication between the first and second openings is accomplished in the module connecting position by means of: A. the flow channel of the first body further comprising an interruption with opposed openings equally spaced as the first and second openings, and B. liquid flow communication between the opposed openings, in the module connecting position, is effected through a channel defined by a first recess defined by the second body and extending in registerable fluid communication with the opposed openings, and by a second recess defined by the first body and extending in fluid communication with the opposed openings.
