Fluid circulation cutting off device for real estate, has waterproof envelopes to collect fluid which escapes from tube, where pressure exerted by escaping fluid acts on piston for moving mechanical system to close supply valve

摘要

The device has waterproof envelopes (X, Y) for collecting a fluid which escapes from a flexible tube (7). The pressure exerted by the escaping fluid acts on a piston (22) for moving a mechanical system (Z) to close a supply valve (1) through a fork (28). The tube (7) passes in a tube (9) that is fixed to two cases (4a, 10a) by links, and is terminated at each end by the links.
