<p>A two-stage pressure regulator with dual safety system, particularly for liquefied-gas cylinders comprising a body (1) which is provided with means (2,3,4) for removable coupling to a liquefied-gas cylinder and forms a first control stage (11) and a second control stage (18) for limiting and regulating the pressure of the gas in output. There is also a pin (15) for actuating the outlet valve of the cylinder, which is controlled by an actuation element which is actuatable by actuation means which can be accessed from outside the body, and further comprising means (40) for the removable locking of the coupling means (2,3,4) which are adapted to prevent the uncoupling and coupling of the body (1) with respect to the cylinder while the actuation pin (15) is in the position for opening the outlet valve. <IMAGE></p> |
