Technical Field
[0001] The utility model relates to the technical field of oxygen manifold pressure reduction, in particular to an oxygen manifold pressure reduction device and an oxygen filling system. Background Technique
[0002] A gas manifold is to centralize the single gas supply sources of individual gas-using points, and to collect the same kind of gas in several gas cylinders into the same pipeline, and then transport the gas to each workplace through this pipeline. It is widely used in hospitals, chemical industries, welding, electronics and scientific research units, solving the problem of gas supply interruption when replacing gas cylinders during the gas supply process.
[0003] However, in the prior art, when replacing gas cylinders during the gas supply process of the existing medical oxygen manifold, the gas in the manifold is manually switched to be transported into the oxygen cylinder. However, the connecting pipe with the oxygen cylinder is easily folded during repeated use, resulting in air leakage at the connection between the oxygen cylinder connecting pipe and the gas transmission pipe of the oxygen manifold device. Moreover, the existing oxygen manifold device cannot adjust the flow rate of the oxygen manifold to adjust the pressure by changing the connection with the oxygen cylinder itself.
[0004] Therefore, we need an oxygen manifold pressure reduction device and an oxygen filling system to solve the gas transmission pressure problem between the existing oxygen manifold pressure reduction device and the oxygen cylinder, and can also prevent air leakage caused by the gas transmission pressure between the oxygen manifold pressure reduction device and the oxygen cylinder. Content of the Utility Model

[0008] Preferably, anti-slip blocks are integrally formed on the outer surface of the sealed connection cylinder. Multiple groups of anti-slip blocks are evenly distributed on the surface of the sealed connection cylinder. A through hole is formed in the top surface of the sealed connection cylinder, and a sealing ring is arranged on the top surface of the sealed connection cylinder. The inner surface of the sealing ring is fixedly connected to the outer surface of the sealing ring, and the inner surface of the sealing ring is fixedly connected to the surface of the gas transmission connection pipe.
[0009] Preferably, the inner surface of the sealed connection cylinder is fixedly connected to the surface of the first sealing gasket. A sealing gasket storage groove is formed in the top surface of the first sealing gasket, and air vents are arranged inside the first sealing gasket. The sealing gasket storage groove communicates with the air vents. The surface of the air vents is movably connected to the surface of the lifting rod. The top surface of the lifting rod is fixedly connected to the bottom surface of the second sealing gasket. The size of the second sealing gasket is the same as the size of the sealing gasket storage groove. A return spring is sleeved on the outer surface of the lifting rod.
[0010] Preferably, both the first sealing gasket and the second sealing gasket are made of rubber materials. The depth of the second sealing gasket is equal to the depth of the sealing gasket storage groove, and the length of the lifting rod fixedly connected to the bottom of the second sealing gasket is equal to the height of the threaded surface on the inner wall of the sealed connection cylinder.

[0012] An oxygen filling system includes an oxygen manifold pressure reducing device.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the inner surface of the sealed connection cylinder is screwed to the surface of the oxygen cylinder input pipe, the oxygen output by the oxygen manifold device flows into the oxygen cylinder connected to the sealed connection cylinder. When the oxygen manifold device is filling the gas cylinder, air leakage may occur at the contact between the gas transmission connection pipe and the sealed connection cylinder. By changing the air flow inside the sealed connection cylinder, the air pressure is reduced. When the input pipe of the gas cylinder screwed inside the sealed connection cylinder is detached, the elastic force of the return spring causes the second sealing gasket to contract to the surface of the sealing gasket storage groove, thus playing a sealing role; further solving the problem of the gas transmission pressure between the existing oxygen manifold pressure reducing device and the oxygen cylinder, and also preventing the air leakage phenomenon caused by the gas transmission pressure between the oxygen manifold pressure reducing device and the oxygen cylinder.
