A regulating chamber 11 is provided inside the regulator 4, and both the input hole 13 and the output hole 14 are connected to the regulating chamber 11.

[0038] Reference Figure 2 and Figure 3The adjustment mechanism includes an input assembly 7, which includes a movable plate 71, a guide column 72, a stopper 73 and a support spring 74. In the present application, the number of the guide column, the stopper 73 and the support spring 74 is four. A mounting ring groove 26 is provided on the circumferential hole wall of the input hole 13. Four guide columns 72 are fixedly installed inside the mounting ring groove 26 along the axial direction of the input hole 13. The movable plate 71 is slidably sleeved on the four guide columns 72.

The support spring 74 is sleeved on the circumferential periphery of the guide column 72, and one end of the support spring 74 is fixedly connected to the stopper 73, and the other end is fixedly connected to the movable plate 71.

[0039] Reference Figure 1 and Figure 2 When low-pressure steam is generated inside the boiler 1, the low-pressure steam flows upward into the shunt pipe 2. A part of the low-pressure steam enters the first steam pipe 3 along a branch outlet of the shunt pipe 2 and is output through the first steam pipe 3 for use; another part of the low-pressure steam flows along another branch outlet of the shunt pipe 2 through the input hole 13 into the regulating chamber 11.

[0040] Reference Figure 2 and Figure 3 When steam flows from the input hole 13 to the regulating chamber 11, the steam pushes the movable plate 71 to slide along the guide post 72 toward the limit block 73, and the limit block 73 limits the sliding position of the movable plate 71, so that the movable plate 71 stops at the middle position of the guide rod, thereby helping to ensure the connection of the input hole 13, and further helping to ensure the smooth flow of steam from the input hole 13 to the regulating chamber 11.

The return spring 94 is fixedly sleeved on the outer periphery of the telescopic rod 93, and one end of the return spring 94 is fixedly connected to the hole wall of the installation hole 16, and the other end is fixedly connected to the inner wall of the adjusting chamber 11.

[0042] Referring to Figure 2 and Figure 5 , the adjusting mechanism further includes a driving assembly 10. An installation chamber 12 is provided inside the regulator 4, and the driving assembly 10 is arranged inside the installation chamber 12. The driving assembly 10 includes a driving motor 101, a driving shaft 102, a winding rack 103, and a traction rope 104. The driving motor 101 is fixedly installed in the installation chamber 12.

One end of the traction rope 104 is fixedly connected to the winding rack 103, and the other end is fixedly connected to the compression body 91.

[0043] Referring to Figure 4 and Figure 5 , after the low-pressure steam enters the adjusting chamber 11, the driving motor 101 operates, driving the driving shaft 102 to rotate, thereby driving the winding rack 103 to wind the traction rope 104, using the traction rope 104 to pull the compression body 91, and further helping to compress the low-pressure steam in the adjusting chamber 11 into high-pressure steam through the compression body 91.

[0044] Referring to Figure 5 , a driving gear 22 is fixedly installed on the output shaft of the driving motor 101. Connecting plates 23 are fixedly installed on both sides of the placing rack on the driving shaft 102. Each end of the two connecting plates 23 is jointly penetrated by a screw rod 24, and the screw rod 24 is rotatably connected to the connecting plate 23. Both screw rods 24 are threadedly connected to the winding rack 103 and are located inside the winding rack 103. One end of each of the two screw rods 24 close to the driving gear 22 is fixedly installed with a driven gear 25, and the driven gear 25 meshes with the driving gear 22.

[0045] Referring to Figure 5When the driving motor 101 is running, the driving gear 22 and the two connecting plates 23 rotate synchronously, thereby driving the two driven gears 25 to rotate synchronously under the meshing action, so that the two screws 24 rotate relative to the connecting plates 23, which helps to drive the unwinding frame 103 to slide along the length direction of the driving shaft 102, which helps to improve the unwinding frame 103 The effect of winding up the traction rope 104.

The sealing ring 18 and the sealing protrusion 19 help to seal the gap between the compression body 91 and the inner wall of the regulating chamber 11, thereby helping to further improve the compression effect of the compression body 91 on the low-pressure steam in the regulating chamber 11.

[0047] Reference Figure 4 and Figure 6 The regulator 4 and the telescopic rod 93 are provided with a ventilation assembly 20, which includes a ventilation pipe 201 and a drainage sleeve 202. The ventilation pipe 201 is inserted into the regulator 4, one end of the ventilation pipe 201 is connected to the outside of the regulator 4, and the other end of the ventilation pipe 201 is inserted into the telescopic rod 93. The drainage sleeve 202 is fixedly installed inside the telescopic rod 93 and sleeved on the circumferential periphery of the ventilation pipe 201. A plurality of ventilation holes 21 are provided on the circumferential side wall of the telescopic rod 93, and the ventilation holes 21 are connected to the drainage sleeve 202. When the compression body 91 moves in the adjustment chamber 11, the mounting hole 16 is connected to the outside of the regulator 4 through the ventilation hole 21, the drainage sleeve 202 and the ventilation pipe 201 in sequence, which helps to ensure the smooth movement of the compression body 91 in the adjustment chamber 11.

[0048] Reference Figure 7 The adjustment mechanism also includes an output assembly 8, which includes a fixed box 81, a rotating rod 82, an output adjustment plate 83 and a sealing ring sleeve 84. The fixed box 81 is fixedly mounted on the outer wall of the regulator 4, the rotating rod 82 penetrates the fixed box 81 and is rotated to be inserted into the output hole 14, the output adjustment plate 83 is fixedly mounted on the rotating rod 82 and is located inside the output hole 14, and the sealing ring sleeve 84 is fixedly mounted on the inner wall of the output hole 14 and is located on the circumferential periphery of the output adjustment plate 83.

A tightening bolt 29 is threadedly mounted on the fixed box 81, and one end of the tightening bolt 29 is tightly pressed against the anti-skid washer 28.

[0049] Reference Figure 2 and Figure 7The output regulating plate 83 is driven to rotate in the output hole 14 by rotating the rotating rod 82, thereby adjusting the flow of high-pressure steam through the output hole 14, so that the high-pressure steam can be output through the second steam pipe 5. The tightening bolt 29 against the anti-slip washer 28 helps prevent the rotation of the rotating rod 82 and helps improve the stability of the output regulating plate 83 in the output hole 14.

[0050] Reference Figure 2 and Figure 8 The shunt pipe 2, the first steam pipe 3 and the second steam pipe 5 are all provided with a heat preservation assembly 6, which includes a sponge layer 61 and a heat preservation cotton layer 62. The sponge layer 61 is fixedly sleeved on the circumference of the shunt pipe 2, the first steam pipe 3 and the second steam pipe 5, and the heat preservation cotton layer 62 is fixedly sleeved on the circumference of the sponge layer 61. The sponge layer 61 and the heat preservation cotton layer 62 help to effectively insulate the transported steam, thereby helping to reduce the probability of steam condensation, and further helping to improve the steam transport effect.

[0051] The implementation principle of the embodiment of the present application is: when low-pressure steam is generated inside the boiler 1, the low-pressure steam flows upward into the bypass pipe 2, a part of the low-pressure steam enters the first steam pipe 3 along a branch outlet of the bypass pipe 2, and is output through the first steam pipe 3 for use; the other part of the low-pressure steam flows along another branch outlet of the bypass pipe 2 through the input hole 13 into the regulating chamber 11.

[0052] When steam flows from the input hole 13 to the regulating chamber 11, the steam pushes the movable plate 71 to slide along the guide post 72 toward the limit block 73, and the limit block 73 limits the sliding position of the movable plate 71, so that the movable plate 71 stops at the middle position of the guide rod, thereby helping to ensure the connectivity of the input hole 13, and further helping to ensure the smooth flow of steam from the input hole 13 to the regulating chamber 11. When steam flows from the regulating chamber 11 to the input hole 13, the movable plate 71, under the action of the supporting spring 74, fits tightly against the groove wall of the mounting ring groove 26, thereby blocking the input hole 13, helping to prevent the steam from flowing from the regulating chamber 11 to the input hole 13, and further ensuring the unidirectional flow of steam in the input hole 13.

[0053] When the low-pressure steam enters the regulating chamber 11, the driving motor 101 operates, driving the driving shaft 102 to rotate, thereby driving the unwinding frame 103 to reel in the traction rope 104, and using the traction rope 104 to pull and pull the compression body 91, thereby helping to squeeze and compress the low-pressure steam in the regulating chamber 11 into high-pressure steam through the compression body 91. By rotating the rotating rod 82, the output adjustment plate 83 is driven to rotate in the output hole 14, thereby adjusting the flow of high-pressure steam through the output hole 14, so that the high-pressure steam can be output through the second steam pipeline 5 for use.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
