[0024] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0025] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0026] Reference Figure 1This embodiment provides a steam regulating device, including a shell 1, which is provided with multiple outlets for connecting to transportation pipelines of different pressures; the shell 1 is provided with a connection port for connecting to transportation pipelines of different pressures, and an input port for inputting steam. Steam of different pressures can be transported separately through different connection ports, avoiding the mixing of steam of different pressures and causing serious energy loss.

[0027] The steam conveying pipe 2 is installed in the shell 1 and is used to distinguish and convey steam of different pressures. It includes a connecting pipe 21 rotatably arranged in the shell 1, and the connecting pipe 21 is provided with a first air outlet 211 and a second air outlet 212; steam is introduced into the shell 1, and the first air outlet 211 is connected to the first outlet of the shell 1. The pressure of the introduced steam is sufficient to drive the connecting pipe 21 to rotate, and the second air outlet 212 is connected to the second outlet of the shell 1; the outer peripheral surface of the connecting pipe 21 is pressed against the inner peripheral surface of the shell 1, and the first air outlet 211 and the second air outlet 212 can be sealed by the rotation of the connecting pipe 21, thereby achieving the sealing of multiple outlets of the shell 1.

[0028] A sealed pipe 22 is provided on the side of the connecting pipe 21 away from the steam port on the shell 1. When the incoming steam pressure is sufficient to push the sealed pipe 22 open, the steam in the connecting pipe 21 passes through the sealed pipe 22 and is then transported through the third outlet of the shell 1. When the steam pressure is high, the pressure continuously acts on the connecting pipe 21 and is sufficient to displace the sealed pipe 22 to the point where the vent hole in the sealed pipe 22 is opened, allowing the high-pressure steam to be transported through a dedicated high-pressure steam pipe.

[0029] By cooperating with the sealing pipe 22 and the connecting pipe 21 , the steam pressure can be roughly divided into three categories: low pressure, medium pressure and high pressure, thereby avoiding the loss of energy in the steam caused by mixing of steam of different pressures.

[0030] As an optional embodiment, a sliding ring 31 is rotatably provided at one end of the connecting pipe 21 away from the sealing pipe 22. The sliding ring 31 is slidably disposed within the housing 1 and is provided with an elastic member 32. The sliding ring 31 is connected to the inner circumference of the housing 1 via the elastic member 32. The elastic member 32 and the sliding ring 31 enable steam pressure to push the sliding plate 31 to pull the elastic member 32, while the connecting pipe 21 can still rotate. When steam is not flowing, the elastic member 32 can reset the steam conveying pipe 2.

[0031] As an optional embodiment, the outer side of the sealing pipe 22 is provided with an external thread 5, and the inner wall of the housing 1 is fixedly provided with an internally threaded sleeve 4 that engages with the external thread 5. Steam pressure acts on the sliding ring 31, pushing the connecting pipe 21 and the sealing pipe 22 to move. At this time, the sealing pipe 22 rotates under the cooperation of the internally threaded sleeve 4 and the external thread 5, thereby enabling the connecting pipe 21 connected to the sealing pipe 22 to rotate, achieving alternating connection with different outlets of the housing 1.

[0032] As an optional embodiment, a sealing portion 6 is provided at one end of the sealing pipe 22 away from the connecting pipe 21. The sealing portion 6 includes a mounting disk 61 disposed on the outside of the sealing pipe 22, a rotating ring 62 rotatably disposed on the mounting disk 61, and a sealing plate 63 disposed on the mounting disk 61. There are multiple sealing plates 63, and the multiple sealing plates 63 are distributed in a circle with the central axis of the sealing pipe 22 as the center, and block the outlet of the sealing pipe 22, thereby preventing steam from being directly transported through the sealing pipe 22 without hindrance. The sealing pipe 22 is blocked by multiple sealing plates 63, and sealing and communication are achieved under the rotation of the rotating ring 62. The outer peripheral surface of the mounting disk 61 fits the inner wall of the shell 1, and there is enough space to install the sealing plate 63, and there is enough space to open the sealing plate 63, thereby achieving sealing and communication of the sealing pipe 22.

[0033] As an optional embodiment, the sealing plate 63 includes a rotating plate 631 movably mounted at the end of the sealing pipe 22 away from the connecting pipe 21, and a connecting curved plate 632 movably mounted on the rotating plate 631. The other end of the connecting curved plate 632 is movably mounted on the rotating ring 62. When the rotating ring 62 rotates, it drives the connecting curved plate 632 to move, and the rotating plate 634 movably connected to the connecting curved plate 632 rotates synchronously with it, allowing steam to be transported through the sealing pipe 22.

[0034] As an optional embodiment, a reset assembly 7 is further included. The reset assembly 7 includes a limit plate 71 disposed outside the mounting plate 61, a curved rod 72 slidably disposed within the limit plate 71, a reset spring 73 covered by the curved rod 72, and a push block 74 connected to the curved rod 72, which cooperates with and passes through the mounting plate 61 and is connected to the rotating ring 62. The push block 74 drives the rotating ring 62 to rotate, and the push block 74 simultaneously drives the curved rod 72 to move, squeezing the reset spring 73. Therefore, when no steam is flowing, the reset spring 73 pushes the push block 74 and the rotating ring 62 to reset.

[0035] As an optional embodiment, the limiting plate 71 is provided with a limiting hole 711 for mounting the arc-shaped rod 72, and is capable of making way for the rotation of the push block 74. A receiving hole is provided in the limiting plate 71 and is connected to the limiting hole 711. The receiving hole is arc-shaped and can cooperate with the arc-shaped rod 72. When the arc-shaped rod 72 rotates, the arc-shaped rod 72 can fit into the receiving hole, and the push block 74 can fit through the limiting hole 711. Therefore, when the push block 74 and the limiting plate 71 rotate relative to each other, the push block 74 slides within the limiting hole 711, and the limiting hole 711 can also make way for the sliding of the push block 74.

[0036] As an optional embodiment, the mounting plate 61 is provided with a mounting groove 611 for movably mounting the rotating ring 62. The mounting plate 61 is provided with a strip-shaped hole 612 that communicates with the mounting groove 611. The push block 74 fits through the strip-shaped hole 612 and is connected to the rotating ring 62. The push block 74 drives the rotating ring 62 to rotate, and the push block 74 simultaneously drives the arc-shaped rod 72 to move, compressing the return spring 73. Therefore, when steam is not flowing, the return spring 73 pushes the push block 74 and the rotating ring 62 to return to their original position.

[0037] As an optional embodiment, a sealing arc plate 8 is provided on the rotating plate 631, which covers the gaps between adjacent rotating plates 631, thereby preventing steam from directly entering the high-pressure transport pipeline through the gaps between the rotating plates 631, thereby reducing the probability of steam leakage.

[0038] As an optional embodiment, the housing 1 further includes a guide ring 9, which is fixedly mounted on the inner wall of the housing 1 and located on the side of the sealing pipe 22 away from the connecting pipe 21. The inner circumference of the guide ring 9 is provided with a clearance ring groove 91. The mounting plate 61 fits into the clearance ring groove 91.

[0039] As an optional embodiment, a stopper 92 is provided in the clearance ring groove 91 to block the push block 74 and push the push block 74 to rotate. When the sealing pipe 22 drives the sealing portion 6 to rotate, the fixed stopper 92 can enable the push block 74 to drive the rotating ring 62 to rotate.

[0040] In summary, low-pressure steam enters the shell 1, and the steam acts on the sliding ring 31, pushing the sliding ring 31 to move, so that the connecting pipe 21 arranged on the sliding ring 31 drives the sealing pipe 22 to rotate. With the cooperation of the external thread 5 and the internal thread sleeve 4, the sealing pipe 22 rotates. At this time, the first air outlet 211 is connected to the low-pressure pipe on the shell 1, and because the steam acts on the sliding ring 31 after entering, providing a continuous force, the first air outlet 211 can be continuously connected to the low-pressure pipe on the shell 1; at this time, the rotating part 6 rotates in the yield ring groove 91, and will not push the reset component 7, so that the sealing pipe 22 remains in a sealed state.

[0041] When medium-pressure steam is introduced, the operating principle is the same, but the force exerted on the sliding ring 31 by the positive-pressure steam is greater. At this time, the rotation angle of the sealing pipe 22 is larger, which can enable the second air outlet 212 to be connected to the medium-pressure pipe on the shell 1 to transport medium-pressure steam; at this time, the rotating part 6 is still rotating in the yield ring groove 91, and still will not push the reset assembly 7, so that the sealing pipe 22 is still in a sealed state.

[0042] When high-pressure steam is introduced, the sealing pipe 22 rotates so that the inner wall of the shell 1 can seal the first air outlet 211 and the second air outlet 212, and the sealing pipe 22 rotates synchronously, so that the sealing part 6 rotates, and the push block 74 contacts with the stop block 92. Since the stop block 92 is fixed, the sealing pipe 22 still drives the sealing part 6 to rotate at this time, and the stop block 92 pushes the push block 74 to rotate, and the push block 74 squeezes the return spring 73. At the same time, the push block 74 drives the rotating ring 62 to rotate, so that multiple sealing plates 63 rotate, thereby releasing the sealing state of the sealing pipe 22, and high-pressure steam can enter the high-pressure pipeline through the sealing pipe 22 for transportation, reducing energy loss.

[0043] Under the joint action of the reset spring 73 and the elastic member 32, when no steam is input, it can be reset to facilitate the next steam transportation adjustment.

[0044] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
