[0027] Please refer to Figures 1-5 As shown, this utility model is a temperature-reducing and pressure-reducing device with flange connection, including a pipeline 1. A pressure regulating valve 11 is fixedly connected to the right side of the pipeline 1. An output pipe 12 is fixedly connected to the top of the pressure regulating valve 11.

[0029] The top of the flange ring six 32 is fixedly connected with a first storage cylinder 3 by screws. The first storage cylinder 3 is fixedly connected with a second storage cylinder 31 by screws. At the center of the top of the second storage cylinder 31, an inlet pipe 33 is fixedly connected. On the left side of the inlet pipe 33, an air pipe 243 is fixedly connected. On the left side of the first storage cylinder 3, an air pump 241 is arranged. The right output end of the air pump 241 is fixedly connected with an air guide pipe 242. The top of the air guide pipe 242 is fixedly connected with the bottom of the air pipe 243.

[0030] Below the air guide pipe 242, a protective ear 47 is arranged. Inside the protective ear 47, a switch piece 46 is rotatably connected through a pin shaft. On the right side of the switch piece 46, a U-shaped block 45 is inserted. On the right side of the U-shaped block 45, an adjusting rod 4 is fixedly connected. On the right side of the adjusting rod 4, a connecting plate 41 is fixedly connected. On the front and back of the connecting plate 41, connecting shafts 42 are fixedly connected.

[0031] The right side of the connecting plate 41 penetrates through the flange ring five 25 and extends to the inside. The outer surfaces of the two connecting shafts 42 are rotatably connected with the inner wall of the flange ring five 25. On the right side of the connecting plate 41, a connecting ear 43 is fixedly connected. Inside the connecting ear 43, a fixing ring 44 is rotatably connected through a pin shaft. Inside the fixing ring 44, a push rod 36 is fixedly connected.

[0032] The top of the push rod 36 penetrates through the bottom of the first storage cylinder 3 and extends to the outside. The outer surface of the push rod 36 is slidably connected with the inner wall of the first storage cylinder 3. The top of the push rod 36 is fixedly connected with an adjusting rubber pad 34. The outer surface of the adjusting rubber pad 34 is fixedly connected with the inner wall of the second storage cylinder 31. At the bottom of the fixing ring 44, two second springs 35 are fixedly connected. By setting the push rod 36, specifically, the top of the push rod 36 will push up the adjusting rubber pad 34, and the adjusting rubber pad 34 will squeeze the air pressure inside the second storage cylinder 31. According to the upward or downward position adjustment of the push rod 36, the valve plug 38 at the bottom can fully control the flow rate of the air flow, so as to control the output of the air flow inside the flow limiting pipe 2, make the air flow flow smoothly to the operation site, avoid waste, and can provide a stable output for the operation site.

[0033] The bottoms of the two second springs 35 are fixedly connected with the bottom of the inner wall of the first storage cylinder 3. The bottom of the push rod 36 penetrates through the sealing ring 37 and extends to the outside. The outer surface of the push rod 36 is slidably connected with the inner wall of the sealing ring 37. The outer surface of the sealing ring 37 is fixedly connected with the inner wall of the flow limiting pipe 2. The bottom of the push rod 36 is fixedly connected with a valve plug 38. The outer surface of the valve plug 38 contacts the inner wall of the flow limiting pipe 2.

[0034] A sliding groove 131 is provided on the left side of the adjusting column 13. A sliding rod 132 is slidably connected to the inner wall of the sliding groove 131. A sliding plug 134 is fixedly connected to the left side of the sliding rod 132. A first spring 133 is fixedly connected to the right side of the sliding plug 134. The right side of the first spring 133 is fixedly connected to the left side of the adjusting column 13. The bottom of the air pump 241 is fixedly connected to a support fastener 24. The inner wall of the support fastener 24 is fixedly connected to the input pipe 231 by screws. By setting the adjusting column 13, specifically by rotating the adjusting column 13 according to the demand, the adjusting column 13 moves to the left and at the same time pushes the first spring 133 to drive the sliding plug 134 to move to the left, thereby controlling the flow rate. When the sliding plug 134 is on the left side of the output pipe 12, the output pipe 12 is closed and adjusted again when waiting to be used, so as to be able to close the air flow out of the output pipe 12 to avoid air leakage, thereby saving resources.

[0035] A specific application of this embodiment is as follows: When in use, first, the flange ring three 22 and the flange ring four 23 are assembled by screws. The right flange ring two 21 is assembled with the flange ring one 14 by screws. The flange ring five 25 is assembled with the flange ring six 32 by screws. After completion, the support fastener 24 is assembled on the outer surface of the sliding groove 131 by screws at a position near the flow-limiting pipe 2 on the outer surface of the sliding groove 131. Subsequently, the air pump 241 is adjusted so that the air output volume of the air pump 241 is stable. Then, the steam flow is guided into the flange ring three 22 through the sliding groove 131 and passes through the inside of the flow-limiting pipe 2. Due to the Z-shaped design of the guiding groove inside the flow-limiting pipe 2, the air pressure first passes through the left Z-shaped notch, then flows upward, and then is blocked by the valve plug 38, thus changing the flow direction to the right. Within the specified flow rate, if the air pressure is too high, when the air pressure flows backward upward through the left Z-shaped notch, a backflow will occur. The backflow will cause the air pressure to squeeze the valve plug 38 upward. As a result, the valve plug 38 pushes the push rod 36 upward. Therefore, the top of the push rod 36 will regularly adjust the rubber pad 34 upward to adjust the air pressure inside the storage cylinder two 31, so that the internal air pressure of the storage cylinder two 31 is not sufficient to squeeze the adjustment rubber pad 34 downward, thereby controlling the distance that the push rod 36 pushes downward. Thus, the fixing ring 44 provided on the outer surface of the push rod 36 moves upward. Once the fixing ring 44 exceeds the limit position, the connecting ear 43 will rise through the pin. Therefore, according to the connecting shaft 42, the connecting plate 41 moves downward, and at the same time, the connecting plate 41 is driven to move downward. Since the left side of the connecting plate 41 is fixedly connected to the adjusting rod 4, and the U-shaped block 45 provided on the left side of the adjusting rod 4 is assembled with the switch piece 46, through the lever principle, the switch piece 46 can be toggled downward, so that the air pump 241 is started. Then, the air pressure is output through the air duct 242, and is inflated into the storage cylinder two 31 through the cooperation of the air duct 243 and the inlet pipe 33. As the internal air pressure of the storage cylinder two 31 increases, the adjustment rubber pad 34 slowly pushes the push rod 36 downward. As a result, the valve plug 38 at the bottom of the push rod 36 moves downward until it returns to the set position. When it returns to the set position, the fixing ring 44 also returns below the adjustment line. Thus, through the lever principle, the switch piece 46 is toggled upward to turn off the air pump 241, thereby achieving the effect of controlling the air pressure. Subsequently, the flow rate is controlled to a certain extent, and then flows to the right. When passing through the sliding plug 134, it flows backward upward. By rotating the adjusting column 13 as required, the adjusting column 13 moves to the left and at the same time pushes the spring one 133 to drive the sliding plug 134 to move to the left, thereby controlling the flow rate. When the sliding plug 134 is on the left side of the output pipe 12, the output pipe 12 is closed and adjusted again when waiting to be used.
