Problems solved by technology

[0002] The manual needle bottle valve of the existing gas cylinder is composed of main components such as a valve body, a valve needle, and a joint body. One or more vent holes must be provided on the upper side of the valve body. There are gaps to adjust the flow of the medium. When deflated, it is necessary to connect the gas conduit and mask to use it. It occupies a large volume, is troublesome to use, and has many shortcomings such as narrow application range. Especially it cannot meet the needs of combat operations. None of them carry an oxygen supply with them, and hypoxia is very dangerous when parachuting, especially for high-altitude aircraft pilots above 10,000 meters
In addition, there is currently a lack of a more convenient smoking and drug cessation device on the market.

Abstract

The invention belongs to the technical field of gas cylinders and discloses a needle-shaped cylinder valve using a tubular type valve needle. A joint body and the tubular type valve needle are connected to a valve body, and the lower section of a pivot through hole is broached for forming a ventilating circular groove; an oxygen channel is machined inside the joint body, a jackscrew is installed at the lower end of the oxygen channel, and a filter screen is installed on the jackscrew; a radial penetrating hole is formed in the lower portion of the tubular type valve needle, boss circular belts are arranged in the middle of the tubular type valve needle, an axial semi-hole communicated with the radial penetrating hole is machined inside a pivot of the tubular type valve needle, and a conical valve element is arranged at the lower end of the tubular type valve needle; a screwed housing is fixed to the middle of the tubular type valve needle, and the lower end of the screwed housing is arranged on the outer circle of the shoulder of a gas cylinder body where the cylinder valve is installed in a sleeving mode. By applying the needle-shaped cylinder valve, the fluid flowing state can be effectively controlled, the flow regulation function can be achieved, and the tubular type valve needle has the kinetic energy transmission function and the function of allowing fluid to pass; by the adoption of the design, the valve structure is simplified, the weight and size are reduced, and the needle-shaped cylinder valve is applicable to oxygen supply and convenient to carry.
