Abstract

The invention discloses a flow-adjustable continuous and pulsed dual-mode oxygen supply module. The module comprises a flow adjusting unit, an air inlet unit, an air outlet unit and an air suction unit. The flow adjusting unit comprises a valve body and a check ring, the valve body synchronously rotates around a valve rod, a plurality of throttling holes and a bypass hole are formed in the valve body, a first air channel corresponding to the throttling holes is formed in a decompression chamber cover plate, and the first air channel and a second air channel communicate with an air inlet sourcethrough the throttling holes and the bypass hole respectively. The air outlet unit comprises an air outlet outer joint, an air outlet valve plate and an air outlet cavity which are arranged on the valve body. The air suction unit comprises an air suction outer joint, an air suction valve plate and an air suction cavity which are arranged on a valve cover, an air inlet convex nozzle communicatingwith the air outlet cavity is arranged on the air suction valve plate, and an air inlet diaphragm used for opening and closing the air inlet convex nozzle is arranged above the air inlet convex nozzle. According to the module, pure mechanical parts are adopted to realize oxygen supply in pulsed and the continuous modes, the flow is adjustable, power supply is not needed in use, and requirements ofspecial occasions are met.

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 a continuous and pulse dual-mode oxygen supply module with adjustable continuous flow. 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 ...

Embodiment Construction

[0031] Such as Figure 1-5 As shown, a flow-adjustable continuous and pulse dual-mode oxygen supply module of the present invention includes a flow adjustment unit 4, an air intake unit 11, an air outlet unit 12, and an inhalation unit 13;

[0032] figure 2 and image 3 The medium flow adjustment unit 4 includes a valve body 44 and a gear ring 42 that rotate synchronously around the valve stem 41. The valve body 44 is provided with a number of throttle holes 48 and a number of bypass holes 47; the function of the flow adjustment module is to decompress The final oxygen is output through the orifice 48 to meet the air flow requirements of different users. The user can adjust the flow gear through the gear ring 42. The decompression chamber cover plate 303 is provided with a first air channel 306 corresponding to the position of the orifice 48, and the valve body 44 of the present invention is provided with an orifice 48 with different apertures, the purpose of which is to re...
