Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] A highly integrated, mechanically open bottle mouth valve, such as figure 1 As shown, it includes a gas cylinder interface 2, a temperature safety valve 3, a ball valve 4, an inflation valve 7, a pressure safety valve 9 and a pressure reducing valve 10, the gas cylinder interface 2 communicates with the gas cylinder, the inflation valve 7, the pressure reducing valve 10 and the gas cylinder The bottle interface 2 forms a three-way structure, and the ball valve 4 is located in the common gas channel of the three-way structure. A spring is arranged between the gas cylinder interface 2 and the ball valve 4. There is a vent hole leading to the outer wall of the sphere. In the inflated state, adjust the direction of the ball valve 4 so that the inflation valve 7 communicates with the through hole, and then communicates with the gas cylinder through the vent...

Abstract

The invention discloses a highly-integrated mechanically-opened type bottle opening valve. The highly-integrated mechanically-opened type bottle opening valve comprises a gas bottle connector, a temperature safety valve, a ball valve, an inflation valve, a pressure safety valve and a pressure reduction valve. The gas bottle connector communicates with a gas bottle, a tee-joint structure is formedby the inflation valve, the pressure reduction valve and the gas bottle connector, and the ball valve is located in a common gas channel of the tee-joint structure. The highly-integrated mechanically-opened type bottle opening valve is provided, the pressure reduction valve, a two-position three-way switch, the inflation valve, the pressure safety valve and the temperature safety valve are combined and integrated, and the characters of high integrity and a small and exquisite structure are achieved. A suspension self-adjustment ball valve structure is adopted, a mechanical opening device is combined, the bottle opening valve is simply and reliably opened, and the low leakage rate is guaranteed.

Description

technical field [0001] The invention relates to a highly integrated, mechanically open bottle mouth valve, which belongs to the technical field of ball valves. Background technique [0002] Bottle-mouth valves are widely used in pressure vessels such as high-pressure gas storage tanks in the chemical industry, civil aviation aircraft life-saving inflatable slides, etc. There are needle valves, butterfly valves, ball valves and other structural forms. In actual application, it is necessary to cooperate with an independent pressure reducer, so that the high-pressure gas source can be used safely after decompression. [0003] The bottle mouth valve is used in the gas cylinder gas supply system and is installed at the outlet of the high-pressure gas cylinder. The bottle mouth valve ensures the gas seal during storage; the gas cylinder valve continues to output stable pressure gas when the gas cylinder valve is opened to exhaust. In the prior art, the bottle mouth valve is usual...
