Embodiment Construction

[0027] As shown in Figures 1 to 7, an embodiment of an emergency oxygen supply valve includes a valve body 1, which is provided with an air supply port 2 for communicating with an oxygen cylinder, an air outlet 3 for outputting oxygen and The gas charging port used to communicate with the oxygen source is actually provided with a gas supply connector at the gas supply port 2 and a corresponding gas charging connector at the gas charging port. The valve body 1 is provided with an air supply passage 100 connecting the air supply port 2 and the air outlet 3 and an inflation air passage 200 connecting the air charging port and the air supply port 2 .

[0028] In order to ensure normal use, a decompression structure 8 is provided on the gas supply circuit 100 for reducing the pressure of the gas input through the gas supply port to a set value to meet the needs of oxygen supply. The decompression structure 8 includes the valve body 1 Some decompression valve chambers are provided w...

Abstract

The invention relates to an emergency oxygen supply valve. The emergency oxygen supply valve comprises a valve body provided with a gas supply opening used for communicating with a gas cylinder and a gas outlet used for outputting oxygen. A gas supply path communicating with the gas outlet is arranged in the valve body, a diaphragm used for cutting off the gas path is arranged on the gas supply path, a striker used for puncturing the diaphragm is movably assembled in the valve body, and the valve body is further provided with a driving mechanism which is in transmission connection with the striker and used for driving the striker to move in the direction of puncturing the diaphragm. As the driving mechanism is directly installed on the valve body, other structures do not need to be arranged during use, gas supply operation is convenient, and the portability of oxygen supply equipment using the oxygen supply valve can be effectively improved.

Description

technical field [0001] The invention relates to an emergency oxygen supply valve. Background technique [0002] In recent years, more and more attention has been paid to safety at home and abroad, especially in the field of lifesaving, an emergency oxygen supply valve that is easy to operate, has good sealing performance, can be opened quickly and can be directly used for breathing is particularly important. There are very few similar oxygen supply valves that can achieve the above functions in China, and such oxygen supply valves abroad have complex structures and relatively high costs. [0003] In the Chinese utility model patent specification with the authorized announcement number CN2165877Y, a gas-storage-type starting device for a chemical oxygen self-rescuer is disclosed, which consists of a high-pressure container and a quick-opening valve. , The striker valve and the oxygen cylinder are threaded and hard-connected. The striker valve is composed of a shell, a diaphr...
