Abstract

PURPOSE:To provide an impulsively supplying device for high pressure gas of which handling is facilitated and of which safety is high by a method wherein a rupture plate is explosively opened with a combustion gas pressure generated by an explosive combustion of combustion mixture gas and the combustion gas pressure is applied to a pressure receiving part of a device connected to the opening. CONSTITUTION:In a life saving rope injecting device, combustible mixture gas is filled in a pressure-proof container 1. While a burret 34 is filled in an injection cylinder 31, the combustible mixture gas is ignited by an igniter 6. With this ignition, the combustible mixture gas filled in the pressure-proof container 1 is explosively burst to break a breaking plate 2. With this breaking, the high pressure combustion gas within the pressure-proof container 1 is injected from the opening into the injection cylinder 31. The gas may act against the injection cylinder 31 to project the burret 34. The life saving rope 35 resiliently connected through an injection of the burret 34 can be expanded. Accordingly, it is possible to use it in place of the conventional type of energy source of powder and hydraulic oil and the like and the device can easily be handled.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a high-pressure gas impact supply device, and more specifically, it is used as an alternative energy source device for explosives, etc. to a lifeline launching device, a riveting device, an explosive device, etc. This invention relates to an impact supply device for high-pressure gas that is used in place of gunpowder or the like as an energy source for molding equipment or the like.

(Prior art) Gunpowder has traditionally been used as an energy source for lifeline firing guns, riveting guns, explosive forming devices, etc., and by exploding the gunpowder and using the energy to fire lifelines, Driving the rivets and shaping.

(Problems to be Solved by the Invention) As mentioned above, when explosives are used as an energy source, there are problems in that not only does it require skill to handle it, but it can also be dangerous if handled incorrectly.

The object of the present invention is to provide a high-pressure gas percussion supply device that solves the above-mentioned problems.

(Measures to Solve the Problem) The present invention provides a pressure-resistant container having an opening sealed with a rupture disc that suddenly ruptures when a pressure exceeding a predetermined pressure is applied, and a pressure-resistant container that Comprising mixing guns ♂ν to 10 and ignition means for igniting the flammable mixed gas filled in the pressure container to explosively burn the flammable mixed gas,
The ignition means applied combustion gas pressure to the pressure receiving part of the ignition device.

(Operation) A pressurized combustible mixed gas consisting of gaseous fuel and air or oxygen containing the necessary amount of oxygen by burning the gaseous fuel is filled in the pressure container. The combustible mixed gas 67 is ignited by the igniter in a state where the combustible mixed gas is filled in the pressure container t. The combustible mixed gas in the pressure vessel used for ignition is explosively combusted, and the pressure vessel is filled with back pressure combustion gas and becomes stable, and the rupture disc suddenly increases the pressure of the combustion gas. It is burst open. There, the rupture disc closes the opening and leaves it open.

As a precaution, the high-pressure combustion gas that had filled the pressure vessel is blown out through the rupture opening of the rupture disc. The injected combustion gas is connected to the opening and supplied to the pressure receiving section of the original device, and high combustion gas pressure is impulsively applied to the pressure receiving section. As a result, it is equivalent to supplying an intense high-pressure gas to the pressure-receiving section, which has the same effect as deflagration of gunpowder.

The regulated pressure of the pressure regulating valve 16 is higher than the regulated pressure of the pressure regulating valve 15, and is set to a pressure that can supply the oxygen t required for complete combustion of the gaseous fuel from the cylinder 12 when the gaseous fuel is filled and mixed into the pressure container 1. It is. 17 and 18 are check valves. The check valve 5 closes the filling port of the pressure container 1.
