Abstract
Improved safety valve, characterized essentially by the fact of comprising a helical spring wound on the stem, whose spring rests its ends on the inner part of the valve cover and on the back of the valve disc, respectively, keeping applied to this against the seat of the valve, establishing the closure to the passage of the fluid, and by providing on the stem two parallel annular recesses, operatively arranged to receive a trigger, retaining elastic that determines, according to the recess in which said trigger is housed, an open position to close the valve, said retention trigger being of the type comprising a screw-adjustable spring that presses a ball, to allow the step by jump from the open to the closed position, for the action of an external agent.
