Integrated oxygen supply valve

Abstract

The invention discloses an integrated oxygen supply valve. A valve body, a valve cover, a filling module, a flow adjusting module and a pulse oxygen supply module are included, wherein the filling module, the flow adjusting module and the pulse oxygen supply module are arranged on the valve body and the valve cover. Oxygen in a gas tank is output by the pulse oxygen supply module after passing through the filling module and the flow adjusting module. The pulse oxygen supply module comprises a gas inlet unit, a gas outlet unit and a gas suction unit. The gas inlet unit comprises a sixth gas wayand a seventh gas way which conduct gas inflow from the same gas inlet source. The gas outlet unit comprises a gas outlet outer connector arranged on the valve body, a gas outlet valve plate and a gas outlet cavity. The gas suction unit comprises a gas suction outer connector arranged on the valve cover, a gas suction valve plate and a gas suction cavity, the gas suction valve plate is provided with a gas inlet protruding nozzle communicating with the gas outlet cavity, and a gas inlet membrane for opening and closing the gas inlet protruding nozzle is arranged above the gas inlet protrudingnozzle. An integrated mechanical structure is adopted in the valve, filling operation and usage are simple and convenient, the different-flow requirements can be met, and different-breathing-manner requirements can be met as well.

Description

technical field [0001] The invention belongs to the technical field of equipment manufacturing, and relates to an automatic gas control valve, in particular to an integrated integrated oxygen supply valve. Background technique [0002] In the production of plateau oxygen supply, underwater oxygen supply and oxygen supply equipment for people with dyspnea in hospitals, oxygen tanks are often used to supply oxygen to users through gas control valves. During use, high-pressure oxygen needs to be filled into the gas tanks first, and then Oxygen is delivered to the user from the tank. Existing gas cylinders have a complicated oxygen supply structure, including independent decompression, flow adjustment and output modules, and there are many conduits and lead wires. The output oxygen flow rate of the oxygen supply equipment in the process of exhaling and exhaling is all constant, only when people inhale, oxygen can be effectively used, and when exhaling, the oxygen is all dischar...

AI Technical Summary

Problems solved by technology

In use, the breathing valve has poor sensitivity to the air outlet of the human body. The user will only supply oxygen in pulses when he is in a state of exercise or inhaling hard. When the human body is in a static state, sleeping state or the valve body is in a horizontal position, it often occurs that there is no air. Or the failure of pulse outlet; in addition, the pulse valve lacks decompression, pressure stabilization and self-sealing filling functions, which limits its popularization and application in many occasions
