Triplicate Diving Gas Valve Device, to be used in conjunction with a Compression Cylinder for a three-in-one purpose of application including:
- siren alarming, Life Coat inflation and facilitating user's Respiration;
- and comprising:
- body which is furnished with a number of orifices each being selectively linked within so that a plurality of interrelated, insulated, isolated spaces are formed within, on one side of the Body is disposed a blocking film or diaphragm which is applied to cover up the first orifice, also a first locking & fastening means which is coupled to said blocking film or diaphragm and to be locked, secured to the first orifice side on the body, and a third orifice which is accessed eventually to the Life Coat;
- a shunting means house in the Body and furnished way between the fist orifice and the second orifice, which shunt means further incorporates:
- an intake coupling of which the interior is in the form of a hollow-set gas conduit extending axially, to an internal end of the intake coupling is locked a hollow-set big sleeving by means of a hollow-set binder, into the big sleeving is seated a screw capable of effecting linear glides therein, to one end of said screw is attached a minor sleeving, symmetrical with respect to the binder, to the same screw is mounted a first spring whose resetting resiliency suffices to bring the minor sleeving tight-sealed to said binder free of externally applied forces, a rocker arm has one elbow attached to the screw, another elbow in contact with said diaphragm, on one end of the intake coupling is fitted an intake means projecting outside the second orifice and accommodating the Compression Cylinder, additionally, on the surface outside the intake coupling are furnished a number of grooves isolated from each other by a plurality of o-ring in an air-tight manner, by the provision to have both the first air intake and the second air intake installed radially to the intake coupling, the conduits inside the intake coupling may be selectively conducted to the first groove and the second groove on the external surface, with the first groove being accessible to the third orifice;
- a Siren Unit, mounted in a sixth orifice of the Body, which unit consists of:
- a hollow-set cylinder, a hollow-set piston penetrating across the Cylinder and a pounding member installed on one end of the Cylinder, the piston being available for reciprocating movements in the Cylinder so that the pounding member on being impinged by the piston in motion will release an alarming siren forthwith, the hollow-set piston being pneumatically communicated to the second groove on the surface outside the intake coupling;
- a Respiratory Mouthpiece, coupled to a ninth orifice on the Body, and in communication with the space inside said diaphragm, such that as the user diver betakes himself to breath the Respiratory Mouthpiece, the diaphragm will shrink due to a pressure drop which materializes in the space within, which in turn compels the rocker arm to pull both the screw and the minor sleeving apart from the binder so that the hermetic sealing condition is frustrated, to follow that, gas resident in the Compression Cylinder will flow into the space inside the diaphragm by way of gas conduit, and that accounting for air supply fed to the diver who respires on it through the Respiratory Mouthpiece;
- siren Button, furnished on an eighth orifice on the Body, and that in common transmission with said first air intake, the first air intake will be driven open when the Siren Button is pressed, whereupon the gas inside the Compression Cylinder will flow to the second groove on the surface outside the intake coupling by way of the gas conduit and the first air intake, next onto the Siren Unit so that the piston is driven to reciprocating movements in the Cylinder concurrent with the release of warning signal appealing for help;
- a charge button, furnished on a fourth on a orifice of the Body and functionally in common with the second air intake, when pressed will drive the second air intake open so that gas store in the Compression Cylinder flows to the first groove on the surface outside the intake coupling by way of Gas Conduit and the Second Air Intake before arriving eventually at the third orifice to inflate the Life Coat.
