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 connecting pipe 105, a pressure regulating mechanism, a power generating mechanism, a cleaning mechanism, and a leak-proof mechanism. Such as 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. Extending to the input end of the valve body 1, 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 the power generation mechanism is used to generate electricity. The impeller 102 and the rotating shaft 101 are located in the valve body. 1 An interference fit inside, the section of the bonnet 103 is convex and has a groove, the inner top wall of the groove of the bonnet 10...

Abstract

The invention discloses a high-precision pressure reducing valve for medical gas. The high-precision pressure reducing valve for the medical gas comprises a valve body, a rotating shaft, an impeller, a valve cover, a metal block, a communicating pipe, a pressure adjusting mechanism, a power generation mechanism, an ash removing mechanism and a leakage preventing mechanism, wherein the valve body is of a hollow structure, the valve body and the valve cover are fixedly connected through a bolt, and the rotating shaft and the valve body are rotationally connected through a bearing in a penetrating mode; and the impeller is in interference fit with the segment, located in the valve body, of the rotating shaft, the section of the valve cover is in an inverted-T shape and is provided with a groove, the metal block is glued to the inner top wall of the groove of the valve cover, and one end of the communicating pipe is fixedly connected with the top wall of the valve cover in a penetrating mode and extends into the groove of the valve cover. The high-precision pressure reducing valve for the medical gas has the following advantages: compared with an existing spring type pressure reducing valve, the high-precision pressure reducing valve for the medical gas is higher in adjusting precision and more convenient to disassemble and maintain, has a certain ash removing function, guarantees cleanliness of exhausted gas, can prevent leakage at the connecting position and is more energy-saving.

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 pressure reducing valve is used to control the opening and closing of the valve body. The opening of the closing part is used to adjust the flow of the medium and reduce the pressure of the medium. At the same time, the opening of the opening and closing part is adjusted by the effect of the pressure behind the valve to keep the pressure behind the valve within a certain range. It is used for oxygen cylinders in general medical treatment. Because the oxygen stored in the oxygen cylinder has a high pressure, it needs to be decompressed and discharged through the pressure ...
