Embodiment 1

[0037] Such as Figure 1-4 As shown, a high-efficiency and low-noise rotary valve includes a valve body assembly, a cam structure, a movable valve plate 9 rotatably arranged in the valve body assembly, and a power device 8 for driving the movable valve plate 9 to rotate. The valve body assembly has an air inlet 4, a first air outlet 1, a second air outlet 2, and a third air outlet 3;

[0038] A gas distribution groove 9-1 penetrates through the movable valve plate 9, and a reinforcing rib 9-2 can be arranged in the gas distribution groove 9-1 to improve the structural strength of the movable valve plate 9 near the gas distribution groove 9-1. Through the rotation of the movable valve plate 9, the air distribution groove 9-1 can connect the air inlet 4 with the second air outlet 2 or / and the third air outlet 3. The second air outlet 2 and the third row Each of the air ports 3 communicates with the first exhaust port 1 through a passage 15, and the passage 15 is blocked with a pus...

Abstract

The invention relates to the technical field of a rotary valve, specifically a high-efficiency and low-noise rotary valve and an oxygen generator of the rotary valve; the rotary valve comprises a valve body assembly, a cam structure, a movable valve block rotationally arranged in the valve body assembly and a power device for driving the movable valve block to rotate; the valve body assembly is provided with an air inlet, a first exhaust port, a second exhaust port and a third exhaust port; an air dividing slot penetrates through the movable valve block; the air dividing slot enables the air inlet to communicate with the second exhaust port or / and the third exhaust port through the rotation of the movable valve block; the first exhaust port provided by the invention communicates with the second exhaust port and the third exhaust port respectively by adopting an independent passage so as to avoid the movable valve block, reduce the sealing difficulty and processing difficulty as well asprocessing cost; the linkage design between a push rod and the movable valve block can be realized by using the cam structure, so that the on / off among the first exhaust port, the second exhaust portand the third exhaust port can be controlled automatically; and then the automatic switching among the three working modes can be realized along the rotation of the valve block.

Description

Technical field [0001] The invention relates to the technical field of rotary valves, in particular to a high-efficiency low-noise rotary valve and an oxygen generator thereof. Background technique [0002] At present, the mainstream oxygen generators are generally double adsorption towers, and the two adsorption towers work alternately, that is, the two adsorption towers alternately separate nitrogen and oxygen. Because the oxygen generator needs to enter one of the adsorption towers, the other An adsorption tower is used to discharge exhaust gas, so a rotary valve (also called a gas distributor valve) is needed. The rotary valve in the prior art has two exhaust pipes, and the two exhaust pipes are connected to the two adsorbers of the oxygen generator. The tower is connected, and the rotary valve is used to control the alternate intake and exhaust of the two exhaust pipes, so as to achieve the alternate operation of the two adsorption towers. However, the existing rotary valve ...
