Gas adaptive integration valve with double air sources

Abstract

The invention discloses a gas adaptive integration valve with double air sources, which is composed of a valve body (1), wherein one end of the valve body (1) is provided with a low-pressure air source air inlet (3) and a high-pressure air source air inlet (4); a self-sealing valve group (10) is installed in each of the low-pressure air source air inlet (3) and the high-pressure air source air inlet (4); a self-regulating voltage-stabilizing valve (5), an ODS (Ozone Depleting Substances) air passage selection component (6) and a main air passage selection component (7) are installed in the valve body (1); the self-regulating voltage-stabilizing valve (5), the ODS air passage selection component (6) and the main air passage selection component (7) respectively abut against the corresponding pressure regulating reed by the respective pressure regulating component; the pressure regulating reed is abutted with a regulating pulling rod (13); the regulating pulling rod (13) is provided witha convex-concave structure which causes the pressure regulating reed to act; two ends of the regulating pulling rod (13) are supported in chutes or holes on the valve body (1); and the valve body (1)is also provided with a locating slot (15) for locating an operating lever (14) on the regulating pulling rod (13). The gas adaptive integration valve with double air sources has simple structure, a manual selection switch is omitted, safety is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to a gas equipment, in particular to a multi-gas source gas equipment, in particular to a dual gas source self-adaptive integrated valve. Background technique [0002] At present, multi-gas sources, especially dual-source gas equipment, have been gradually accepted by the market, which greatly expands the choice of gas sources for users and facilitates users and manufacturers. In order to improve the safety of gas equipment and facilitate users, a lot of research has been done on the key components of gas equipment, such as dual-air source regulator valves, dual-air source ODS systems, and dual-air source nozzles. Various self-adaptive devices, most of these devices can realize automatic matching according to the different air pressure of the air source, which greatly simplifies the operation, but these devices must be connected to the dual air source regulator valve, dual air source ODS, etc. System, dual air source nozzles ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the self-adaptive device in the existing multi-gas source gas equipment must be connected through a plurality of selection switches, resulting in complex structure and easy operation errors, and to design a device that can complete all operations by operating only one switch. The switch selects to output the corresponding gas source to the adaptive dual gas source regulator valve, dual gas source ODS and dual gas source nozzle (the dual gas source gas adaptive integrated valve of the main gas path selection switch
