Embodiment

[0030] refer to Figure 1-7 , a high-precision medical gas pressure reducing valve, including a valve body 1, a rotating shaft 101, an impeller 102, a valve cover 103, a metal block 104, a communication pipe 105, a pressure regulating mechanism, a power generating mechanism, a dust cleaning mechanism, and a leak prevention mechanism. like figure 1 As shown, the valve body 1 includes an output end and an input end. The valve body 1 is a hollow structure. The valve body 1 and the valve cover 103 are fixedly connected by bolts. The impeller 102 is also arranged in the input end of the valve body 1. The impeller 102 is driven to rotate by the input high pressure gas, and generates electricity through the power generating mechanism. The impeller 102 and the rotating shaft 101 are located in the valve body. 1. A section of interference fit inside the valve cover 103, the cross section of the valve cover 103 is convex and is provided with a groove, the inner top wall of the valve co...

Abstract

The invention discloses a high-precision medical gas decompression valve, which includes a valve body, a rotating shaft, an impeller, a valve cover, a metal block, a connecting pipe, a pressure regulating mechanism, a power generation mechanism, a dust cleaning mechanism, and a leak-proof mechanism. The body is a hollow structure, the valve body and the valve cover are fixedly connected by bolts, the rotating shaft and the valve body are connected through the rotation through bearings, the impeller and the rotating shaft are in a section of interference fit inside the valve body, and the The cross-section of the valve cover is convex and has a groove. The inner top wall of the groove of the valve cover is glued with a metal block. One end of the communication pipe is fixedly connected with the top wall of the valve cover and extends to the valve cover. inside the groove. The advantage is that: compared with the existing spring-type pressure reducing valve, the present invention has higher adjustment accuracy, is more convenient for disassembly and maintenance, and has a certain cleaning function, which ensures the cleanness of the exhaust gas and prevents connection Leakage at places, while more energy efficient.

Description

technical field [0001] The invention relates to the technical field of pressure reducing valves, in particular to a high-precision medical gas pressure reducing valve. Background technique [0002] The valve body is a common tool in our life. It is set in the pipeline for opening and closing or adjustment. In the medical industry, the pressure reducing valve is also one of the commonly used valve bodies. The opening of the closing piece can adjust the flow of the medium, reduce the pressure of the medium, and at the same time adjust the opening of the opening and closing piece with the help of the pressure behind the valve to keep the pressure behind the valve within a certain range. Since the oxygen is stored in the oxygen cylinder with a large pressure, it needs to be decompressed and discharged through the pressure reducing valve before it can be used. [0003] In the prior art, the existing pressure reducing valve often uses a spring as an adjustment component, and its ...
