A CONDUIT SYSTEM FOR TRANSPORTING A GASEOUS MEDIUM, SUITABLE FOR INTRAMURAL INSTALLATION

摘要

A conduit system for transporting a gaseous medium, suitable for intramural installation, including conduits, connector fittings, distributor fittings. The elements of the conduit system are arranged within a protective housing (9), delimiting a gas-tight space containing a gaseous filling of a pressure higher than the working pressure of the medium transported in the conduit system, and that the space of the protective housing (9) is connected with an actuator (10) of a pneu­matically operated cut-off valve (3) inserted into the conduit system prior to the point of the latter's entry point into a solid structural element, such as a wall (1, 7) or a ceiling of a building. In case of any failure of the elements of the conduit system, whether the breakdown or damage is of internal or external origin, the alteration of the pressure conditions in the conduit system and within the protective housing (9) results in the immediate activation of the cut-off valve (3) positioned prior to the entry point of the conduit system, which disconnects safely the entire conduit system from the supply network, preventing thereby that the gaseous medium, most frequently gas, supplied from the network should cause accident, damage or injury of any kind.
