Abstract:
A triplicate diving gas valve device for use with a compression cylinder for a three-in-one purpose of siren alarming, life coat inflation and facilitating a user's respiration, and comprising:a body having a plurality of orifices, each being selectively linked within so that a plurality of interrelated, insulated, isolated spaces are formed within the body, on one side of the body is disposed a blocking diaphragm applied so as to cover up a first orifice, a first locking and fastening device coupled to said blocking diaphragm and secured to the first orifice side on the body, and a third orifice adapted to be connected to a life coat; a shunting device housed in the body between the first orifice and a second orifice, which shunt device includes: an intake coupling of which an interior has a gas conduit extending axially, an internal end of the intake coupling is locked a hollow first sleeving by a hollow binder, into the first sleeving is seated a screw attached to a second sleeving, symmetrical with respect to the binder, and to a first spring having resetting resiliency sufficient to bring the second sleeving tight-sealed to said binder free of externally applied forces; a rocker arm having one elbow attached to the screw and another elbow in contact with said diaphragm; on one end of the intake coupling has an intake projecting outside the second orifice and adapted to be connected to a compression cylinder; on an outside surface of the intake coupling having first and second grooves isolated from each other by a plurality of o-rings in an air-tight manner; a first air intake and a second air intake located radially of the intake coupling, such that conduits inside the intake coupling may be selectively conducted to the first groove and the second groove with the first groove being connected to the third orifice; a siren unit, mounted in a sixth orifice of the body, which unit includes: a hollow cylinder, a hollow piston penetrating across the cylinder and a pounding member installed on one end of the cylinder, the piston reciprocating in the cylinder so that the pounding member is impinged by the piston to generate an alarming siren, the hollow piston pneumatically communicating with the second groove on the intake coupling; a respiratory mouthpiece, coupled to a ninth orifice on the body, and in communication with space inside said diaphragm, such that as a user diver inhales, the diaphragm will shrink due to a pressure drop in the space within, which in turn controls the rocker arm to pull both the screw and the second sleeving apart from the binder so that a hermetic sealing condition broken, enabling air to flow into a space inside the diaphragm by way of a conduit, and be fed to the diver; a siren button, on an eighth orifice on the body, in common transmission with said first air intake, such that the first air intake will be driven open when the siren button is pressed, whereupon gas will flow to the second groove and into the siren unit so that the piston is driven to reciprocating movement; and, a charge button, on a fourth orifice of the body in common with the second air intake, such that, when pressed, the second air intake will open so that gas flows to the first groove on the surface outside the intake coupling by way of the second air intake and the third orifice.
