Embodiment Construction

[0027] Such as Figure 1 to Figure 7 As shown, 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 an air outlet for communicating with an oxygen source. In fact, there is an air supply connector at the air supply port 2, and a corresponding inflation connector at the inflation 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 with valv...

Abstract

The invention relates to an emergency oxygen supply valve, which comprises a valve body with an air supply port for communicating with a gas cylinder and an air outlet for outputting oxygen. There is a diaphragm on the gas circuit to cut off the gas path, and a striker is installed in the valve body to pierce the diaphragm. The valve body is also equipped with a drive connected to the striker to drive the striker toward the direction of piercing the diaphragm. Mobile drive mechanism. Since the driving mechanism is directly installed on the valve body, no other structures need to be arranged during use, the air supply operation is relatively convenient, and the portability of the 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...
