[0029] Please see Figures 1 to 6 As shown in the figure, this application provides an air flow and pressure regulating device, including a base 100, an air inlet pipe 120, an air outlet pipe 130, and a regulating component.
[0030] The base 100 is provided with a first channel 110 extending along a first direction, the first channel 110 penetrating the base 100 along the first direction to form a first opening 101 and a second opening 102; an air inlet pipe 120 is connected to the side wall of the base 100 and communicates with the first channel 110; an air outlet pipe 130 is connected to the second opening 102 and communicates with the first channel 110; the adjustment assembly includes a valve core 150, a valve sleeve 140 and an adjustment rod 160, the valve sleeve 140 is disposed in the first channel 110, and the valve sleeve 140 is provided with a first opening 101 and a second opening 102 extending along the first direction. The extended second channel 141 passes through the valve sleeve 140 along the first direction to form a third opening 142 and a fourth opening 143. The valve core 150 is disposed in the second channel 141. The valve sleeve 140 is also provided with a third channel 144 connected to the second channel 141. The adjusting rod 160 is disposed in the first channel 110 and is threadedly connected to the base 100 at the first opening 101. The adjusting rod 160 drives the valve core 150 to move along the first direction. The end of the valve core 150 near the fourth opening 143 can seal the fourth opening 143.
[0031] By rotating the adjusting rod 160, the pressure applied by the adjusting rod 160 to the valve core 150 is changed. When the adjusting rod 160 moves closer to the valve core 150, the pressure applied to the valve core 150 increases. At this time, the valve core 150 can be pushed closer to the second opening 102 by the entry of gas at a lower pressure, opening the fourth opening 143, so that the gas can flow out. When the adjusting rod 160 moves away from the valve core 150, the pressure applied to the valve core 150 increases. At this time, the valve core 150 can be pushed closer to the second opening 102 by the entry of gas at a higher pressure, opening the fourth opening 143, so that the gas is output from the gas outlet pipe 130, thereby realizing the adjustment of the gas pressure output from the gas outlet pipe 130.
[0032] In one specific implementation, the valve sleeve 140 is provided with an assembly groove 145 near the third opening 142, and the valve core 150 is provided with a first abutment plate 151 near the third opening 142. The adjusting assembly also includes a first elastic element 152, which abuts against the assembly groove 145 and the first abutment plate 151. The second elastic element 162 is used to provide the valve core 150 with a pressure in the direction near the first opening 101 under normal conditions, so that the gas flow pressure regulating device can require a certain gas pressure to enter under normal conditions in order to open the fourth opening 143 and allow the gas to flow out.
[0033] In one specific implementation, the adjustment assembly further includes a second abutment plate 161, a second elastic member 162, and an abutment member 163. The second abutment plate 161 is disposed within the first channel 110 and abuts against one end of the adjustment rod 160 near the base 100. The abutment member 163 abuts against the first abutment plate 151. This is to improve the stability of the rotational adjustment of the adjustment rod 160.
[0034] In one specific implementation, the abutment member 163 includes a third abutment plate 164 and an abutment rod 165, which form a T-shaped structure. The third abutment plate 164 abuts against the second elastic member 162, and the abutment rod 165 abuts against the first abutment plate 151. This is used to improve the sealing performance within the first channel 110.
[0035] In one specific implementation, a sealing element 170 is fitted onto the abutment rod 165, and the sealing element 170 abuts against the inner wall of the base 100 to seal the first channel 110. This further improves the sealing performance within the first channel 110.
[0036] In one specific implementation, a first sealing ring 180 is fitted onto the end of the valve core 150 near the fourth opening 143.
[0037] In one specific implementation, a connector 190 is provided at the second opening 102, the connector 190 is threadedly connected to the base 100, and the air outlet pipe 130 is provided on the connector 190.
[0038] In one specific implementation, a second sealing ring 200 is also fitted on the connector 190, and the second sealing ring 200 abuts against the inner wall of the base 100.
[0039] In one specific implementation, the valve core 150 is further provided with an annular structure 153, which abuts against the inner wall of the valve sleeve 140 to seal the second channel 141. The annular structure 153 is located on the side of the third channel 144 away from the fourth opening 143. This is to improve the sealing performance within the second channel 141, allowing gas to flow out only from the fourth opening 143 until it flows to the outlet pipe 130.
[0040] In summary, the gas flow and pressure regulating device provided in this embodiment changes the pressure applied by the regulating rod 160 to the valve core 150 by rotating the regulating rod 160. Gas enters the base 100 from the inlet pipe 120, and then enters the valve sleeve 140 through the third channel 144. The gas pushes the valve core 150, causing it to move closer to the second opening 102, thereby opening the fourth opening 143. Gas can then flow out from the fourth opening 143 and be output from the outlet pipe 130. The second elastic element 162 is used to apply a force to push the valve core 150 closer to the first opening 101. Through the arrangement of the regulating rod 160, the first elastic element 152, the second elastic element 162, the valve core 150, and the valve sleeve 140, the gas pressure output from the outlet pipe 130 is increased. The overall structure is simple, improving the ease and stability of regulation.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
