Description

Technical Field

[0001] This utility model relates to the field of pipeline leak prevention, and in particular to a modular steam heating leak prevention device. Background Technology

[0002] A combined heat and power (CHP) plant is a thermal power plant that generates electricity while simultaneously using steam extracted or exhausted from a steam turbine to provide heat to users. Its main working principle is to utilize the hot water generated after the power plant produces electricity, reheating it for heating. CHP plants require a large number of heating pipes to form a complete heating network. Over time, this network is prone to leaks. In the event of a leak, steam can disperse into the surrounding space.

[0003] According to the prior art, "A leak-proof device for heating pipe network in thermal power plant", with announcement number "CN217482548U", the inner heating pipe of this device can be used to transport hot steam. When the inner heating pipe leaks, the leaked steam is temporarily stored in the leak-proof outer pipe to prevent it from leaking out. However, the steam leakage will cause changes in the internal air pressure of the pipe, affecting the subsequent transport of heating steam by the pipe.

[0004] Therefore, a modular steam heating leak prevention device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a modular steam heating leak prevention device to solve the above problems, thereby improving the problem that steam leakage will cause changes in the internal air pressure of the pipe body, affecting the subsequent delivery of heating steam by the pipe body.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a modular steam heating leak-proof device, comprising: a heating pipe, one end of which is provided with a connecting pipe; a leak-proof mechanism, which is disposed on the surface of the heating pipe and the connecting pipe, the surface of which extends into the interior of the pipe body; wherein, the leak-proof mechanism includes fasteners installed on the surface of the heating pipe and the connecting pipe, and the interior of both the heating pipe and the connecting pipe is provided with a pipe body leak-proof component, and a connecting leak-proof component is provided between the two pipe body leak-proof components, the surface of which extends into the interior of the fasteners.

[0007] Preferably, the two pipe-body leak-proof components include a mesh tube disposed on the inner wall of the heating pipe and the connecting pipe. An inner tube is connected to the inner wall of the mesh tube, and the surface of the inner tube has multiple annular grooves. A rubber ring is fixedly connected to the end of the mesh tube, and the rubber ring is made of soft rubber. The mesh tube assists in preventing leakage of the gas flowing inside the inner tube. When gas leaks out of the inner tube, the multi-regional mesh surface of the mesh tube limits further leakage of steam, thereby reducing continuous leakage of steam heating.

[0008] Preferably, the connection leak-proof assembly includes an outer ring sleeved outside the rubber ring, the outer ring being threadedly connected to the inner wall of the adjacent heating pipe and connecting pipe, and a connecting ring being fixedly connected to the surface of the outer ring away from the rubber ring, the surface of the connecting ring being in contact with the end of the adjacent heating pipe and connecting pipe.

[0009] Preferably, the leak-proof connection assembly includes an inner ring fitted onto the ends of the two inner tubes. A sealing ring is fixedly connected inside the inner ring, and the surface of the sealing ring contacts the end of the adjacent inner tube. The sealing ring is made of rubber. This device ensures the stability of the connection between the two inner tubes through the inner ring and the sealing ring, and reduces the occurrence of steam leakage at the connection point due to the action of the sealing ring.

[0010] Preferably, the fastener includes two flanges that are respectively fixedly connected to the ends of the heating pipe and the connecting pipe, and the two flanges are provided with ring-shaped grooves on opposite sides.

[0011] Preferably, an air bladder ring is fixedly connected to the surface of the connecting ring away from the outer ring, and the air bladder ring is located inside the fastener. The outer ring ensures a more stable connection between the heating pipe and the connecting pipe, and the air bladder ring, along with the ring-shaped groove, provides protection against leakage at the connection point.

[0012] Preferably, a positioning ring is engaged with the inner wall of the annular groove, and the surface of the positioning ring extends into the interior of the grid tube. The positioning ring, through the annular groove on the surface of the inner tube, assists in positioning the grid tube, reducing the deformation caused by leakage steam contacting the grid tube, and improving the protective effect of the grid tube against leakage steam.

[0013] The beneficial effects of this utility model are:

[0014] 1. The above-mentioned modular steam heating leak prevention device can prevent steam from leaking inside the modular pipeline under the action of the pipe leak prevention component. The device uses a grid tube to assist in preventing gas from leaking inside the inner pipe. When gas leaks out of the inner pipe, the grid tube has a multi-area grid pattern on its surface, which limits the continued leakage of steam to the outside, thereby reducing the continuous leakage of steam heating and ensuring that the gas pressure inside the conveying pipe does not change significantly.

[0015] 2. By setting up connecting anti-leak components and fasteners, the device can stabilize the connection between the two inner tubes through the internal ring and the sealing ring, and reduce the occurrence of steam leakage at the connection point through the sealing ring. Furthermore, the airbag ring and the ring groove provide protection against leakage at the connection point. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-4As shown, a modular steam heating leak-proof device includes: a heating pipe 1, with a connecting pipe 2 at one end of the heating pipe 1; a leak-proof mechanism 3, which is disposed on the surface of the heating pipe 1 and the connecting pipe 2, and the surface of the leak-proof mechanism 3 extends into the interior of the pipe body; wherein, the leak-proof mechanism 3 includes fasteners 33 installed on the surface of the heating pipe 1 and the connecting pipe 2, and pipe body leak-proof components 31 are disposed inside the heating pipe 1 and the connecting pipe 2, and a connecting leak-proof component 32 is disposed between the two pipe body leak-proof components 31, and the surface of the connecting leak-proof component 32 extends into the interior of the fasteners 33;

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the two pipe leak-proof components 31 include a grid pipe 311 disposed on the inner wall of the heating pipe 1 and the connecting pipe 2. An inner pipe 312 is connected to the inner wall of the grid pipe 311. Multiple annular grooves 313 are opened on the surface of the inner pipe 312. A rubber ring 315 is fixedly connected to the end of the grid pipe 311. The rubber ring 315 is made of soft rubber. A positioning ring 314 is snapped into the inner wall of the annular groove 313. The surface of the positioning ring 314 extends into the interior of the grid pipe 311.

[0024] The device uses a grid tube 311 to assist in preventing gas leakage inside the inner tube 312. When gas leaks out of the inner tube 312, the grid tube 311, with its multi-area grid pattern, restricts further steam leakage, thus reducing continuous steam leakage. Furthermore, the positioning ring 314, through the annular groove 313 on the surface of the inner tube 312, helps to position the grid tube 311, reducing deformation caused by leaking steam and improving the protective effect of the grid tube 311 against leaking steam.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the connection leak-proof assembly 32 includes an outer ring 321 sleeved outside the rubber ring 315. The outer ring 321 is threadedly connected to the inner wall of the adjacent heating pipe 1 and connecting pipe 2. A connecting ring 324 is fixedly connected to the surface of the outer ring 321 away from the rubber ring 315. The surface of the connecting ring 324 contacts the end of the adjacent heating pipe 1 and connecting pipe 2. The connection leak-proof assembly 32 includes an inner ring 322 sleeved at the end of the two inner pipes 312. A rubber sealing ring 323 is fixedly connected inside the inner ring 322. The surface of the rubber sealing ring 323 contacts the end of the adjacent inner pipe 312. The rubber sealing ring 323 is made of rubber.

[0026] An airbag ring 325 is fixedly connected to the surface of the connecting ring 324 away from the outer ring 321. The airbag ring 325 is located inside the fastener 33. The fastener 33 includes two flanges 331 that are fixedly connected to the ends of the heating pipe 1 and the connecting pipe 2, respectively. The two flanges 331 have ring-shaped grooves 332 on opposite sides. This device stabilizes the connection between the two inner pipes 312 through the inner ring 322 and the sealing ring 323. Under the action of the sealing ring 323, the occurrence of steam leakage at the connection is reduced. Under the action of the outer ring 321, the connection between the heating pipe 1 and the connecting pipe 2 is made more stable. And under the action of the airbag ring 325 and the ring-shaped groove 332, a protective effect is formed against leakage at the connection.

[0027] In use, the grid tube 311 of this invention assists in preventing gas leakage inside the inner tube 312. When gas leaks out of the inner tube 312, the positioning ring 314, through the annular groove 313 on the surface of the inner tube 312, helps to position the grid tube 311 because the surface of the grid tube 311 is a multi-region grid. The inner ring 322 and the sealing ring 323 stabilize the connection between the two inner tubes 312. The outer ring 321 makes the connection between the heating pipe 1 and the connecting pipe 2 more stable. The airbag ring 325 and the annular groove 332 provide protection against leakage at the connection.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
