The medical gas pressure reducing tank 100 of the present embodiment is operated in different modes, and the respective gas flows and the corresponding functions are described below with reference to fig. 3 to 7. And (3) injection: in fig. 3 to 7, the handle of each valve is opened when the handle is transverse to the valve flow path, and the handle is closed when the handle is perpendicular to the valve flow path.
Fig. 3 is a schematic view showing the flow direction of the gas in the gas supply mode of the medical gas pressure reducing tank according to the present embodiment, which is operated in Shan Zhilu mode, and the flow direction of the gas in this mode is shown by the dotted arrows in fig. 3. Wherein, the high pressure gas introduced by the gas inlet pipe 21 is decompressed only by the first pressure reducer branch, and then the low pressure gas is output through the flow meter 51 and the gas outlet pipe 22, and is further supplied to each ward of the floor to which the gas is supplied. In this mode, the first valve 31, the second valve 33, the sixth valve 72, and the ninth valve 75 are opened, and the third valve 34, the fourth valve 36, the fifth valve 71, the seventh valve 73, and the eighth valve 74 are closed; in addition, when the air pressure in the third connection pipe 63 is excessively large, the relief valve 76 is automatically opened and relieved. The first pressure gauge 41 shows the gas pressure before the depressurization, and the second pressure gauge 42 shows the gas pressure after the depressurization.
Fig. 4 is a schematic view showing the flow direction of the gas in the gas supply mode of the medical gas pressure reducing tank according to the present embodiment, in which the flow direction of the gas is shown by the dotted arrow in fig. 4. The second pressure reducer branch is used as a standby branch, and when the air quantity of the first pressure reducer branch is insufficient, the second pressure reducer branch is opened, so that the air supply quantity is increased; that is, the high-pressure gas introduced into the gas inlet pipe 21 is depressurized through both the first and second depressurizer branches, and then the low-pressure gas is outputted through the eighth valve 74 and the gas outlet pipe 22, thereby being supplied to each ward of the floor to which it belongs. In this mode, the first, second, third, fourth, and eighth valves 31, 33, 34, 36, and 74 are opened, and the fifth, sixth, seventh, and ninth valves 71, 72, 73, and 75 are closed. Similarly, the first pressure gauge 41 displays the gas pressure before the depressurization, and the second pressure gauge 42 displays the gas pressure after the depressurization.
Fig. 5 is a schematic view showing the flow direction of the medical gas in the line cleaning mode, in which the medical gas pressure reducing tank according to the present embodiment is operated, and the flow direction of the gas in the line cleaning mode is shown by the dotted arrow in fig. 5. In the background art of the present utility model, it is mentioned that when the internal pipeline and the devices of the existing pressure reducing box are welded or screwed together during assembly, some debris impurities are inevitably generated and remain in the pipeline. The mode shown in fig. 5 aims at discharging impurities in the pipe to the outside. Specifically, in this mode, the first valve 31, the second valve 33, the third valve 34, the fourth valve 36, the eighth valve 74, and the ninth valve 75 are closed, and the fifth valve 71, the sixth valve 72, and the seventh valve 73 are opened. The high-pressure gas introduced into the gas inlet pipe 21 thus purges a part of the pipes so that impurities present in these pipes are discharged to the outside of the pipes through the seventh valve 73. The seventh valve 73 is preferably a mini ball valve. In addition, the exhaust end of the seventh valve 73 may also be used as a gas sampling end; for example, when it is desired to detect the purity of the incoming gas, the seventh valve 73 may be opened so that some gas is collected from the exhaust end of the seventh valve 73 for assay analysis.
Fig. 6 is a schematic view showing the flow direction of the medical gas in the bypass opening mode of the medical gas pressure reducing tank according to the present embodiment, and the flow direction of the gas in the bypass opening mode is shown with reference to the dotted arrow in fig. 6. The mode shown in fig. 6 is a mode in which the air supply is directly performed without depressurizing when the air consumption demand is extremely large (when the air supply mode of the two-branch pressure reducer shown in fig. 4 is not sufficient). Specifically, in this mode, the first valve 31, the second valve 33, the third valve 34, the fourth valve 36, the sixth valve 72, the seventh valve 73, the ninth valve 75 are closed, and the fifth valve 71, the eighth valve 74 are opened. The high-pressure gas introduced by the gas inlet pipe 21 directly enters the gas outlet pipe 22 through the fifth valve 71 and the eighth valve 74, and is further supplied to each ward of the floor to which the high-pressure gas belongs.
Fig. 7 is a schematic view showing the flow direction of the medical gas in the flow meter maintenance mode of the medical gas pressure reducing tank according to the present embodiment, and the flow direction of the gas in this mode is shown with reference to the dotted arrow in fig. 6. Sometimes, the flowmeter needs to be overhauled or replaced, but the air supply is not allowed to be interrupted at the moment, so the utility model designs the mode, namely, the flowmeter can be overhauled temporarily while the air supply is ensured. Specifically, in this mode, the first valve 31, the second valve 33, and the eighth valve 74 are opened, and the third valve 34, the fourth valve 36, the fifth valve 71, the sixth valve 72, the seventh valve 73, and the ninth valve 75 are closed. The first pressure gauge 41 shows the gas pressure before the depressurization, and the second pressure gauge 42 shows the gas pressure after the depressurization. In this mode, the high-pressure gas introduced into the gas inlet pipe 21 is depressurized only by the first depressurizer branch, and then low-pressure gas is outputted through the eighth valve 74 and the gas outlet pipe 22, thereby being supplied to each ward of the floor to which it belongs.
From the above, the medical gas pressure reducing box of the embodiment is provided with the pressure reducing device and the flow device in one box body at the same time, so that the medical gas pressure reducing box is higher in integration level, better in integrity and easier to manage and maintain. In addition, the first pressure reducer branch circuit for main use, the second pressure reducer branch circuit for standby use and the bypass pipeline used in extreme cases are arranged in the embodiment, so that the air supply quantity of the pressure reducing box can be flexibly adjusted to adapt to the change of the air consumption requirement of each floor. In addition, in the present embodiment, through the straight-through path formed by the fifth valve 71, the sixth valve 72 and the seventh valve 73, the high-pressure gas introduced by the air inlet pipe 21 can be utilized to purge and discharge impurities existing in part of the pipelines. Finally, the medical gas pressure reducing box of the embodiment can realize various working modes by controlling the opening and closing of each valve.
The foregoing is a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model and are intended to be comprehended within the scope of the present utility model.
