摘要

The invention relates to a valve that includes a body (1) having an inlet (12) to an inside housing (11), and an outlet (22) from said housing, there being a plug (3) between the inlet (12) and the outlet (22). The body (1) has a cover (2) for closing the housing (11), provided with two or more outlets (22) for the removal and/or flow of gas. The housing (11) has a ring seat (14) facing an elastic seal (15), and the plug (3) and a ring fitting (31) facing said elastic seal (15), there being a compression spring (4) located against the rear part of the plug (3), which, when in an inactive position, forces said plug (3) toward a closed position against the elastic seal (15).
