Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of heating pipe networks, and in particular, to a heating pipe network and a heating pipeline assembly thereof. Background Art
[0002] For areas with cold weather, centralized heating is usually used. The thermal power plant heats the heating liquid and then transports the heating liquid to the user's room through the heating pipes in the heating network to provide heating to the user.
[0003] In actual use, the heating liquid in the heating pipe is often mixed with gas (such as air). This part of the gas may cause air hammer or air blockage when it moves with the heating liquid in the heating pipe. The air hammer in the air hammer phenomenon may cause damage to the heating pipe after colliding with the heating pipe. The air blockage phenomenon will reduce the flow rate of the heating pipe and affect the heating temperature for users.
[0004] Therefore, in the prior art, an exhaust pipe is usually installed on the heating pipe to regularly discharge the gas in the heating pipe. However, in cold outdoor areas (for example, areas where the outdoor temperature is below 0°C), after the exhaust pipe is closed, the liquid carried by the gas entering the exhaust pipe will accumulate in the exhaust pipe to form "dead water" and condense into ice, thereby causing the exhaust pipe to be blocked, and then the exhaust pipe cannot be exhausted. Therefore, in the prior art, an electric heating tape is usually installed outside the exhaust pipe, and the exhaust pipe is heated by the electric heating tape to allow the "dead water" in the exhaust pipe to flow and prevent the "dead water" in the exhaust pipe from condensing into ice.
[0005] However, using electric heating tape to heat the exhaust pipe will consume a lot of electricity on the one hand, and lose its heating function when the power supply of the electric heating tape is disconnected on the other hand, and its reliability is poor. Summary of the invention
[0006] The purpose of the present invention is to provide a heating pipe network and a heating pipe assembly thereof to solve the technical problems existing in the related art.

[0009] Optionally, the inclined section is inserted into the exhaust port and fixedly connected to the curved section, and a depth of the inclined section inserted into the exhaust port is less than a wall thickness of the curved section.
[0010] Optionally, an end surface of one end of the inclined section inserted into the exhaust port is a plane parallel to a horizontal plane.
[0011] Optionally, the heating pipe assembly includes a plurality of pipe clamps, and the plurality of pipe clamps are arranged at intervals along the extension direction of the exhaust pipe, and the exhaust pipe is fixed to the bending section through the plurality of pipe clamps.
[0012] Optionally, the heating pipe assembly further includes a thermal insulation layer, and the thermal insulation layer is coated on the outside of the curved section and the exhaust pipe.
[0013] Optionally, the thermal insulation layer includes at least a first thermal insulation layer and a second thermal insulation layer, the first thermal insulation layer is coated on the outside of the curved section and the exhaust pipe, and the second thermal insulation layer is coated on the outside of the second thermal insulation layer and covers the seam of the first thermal insulation layer.

The above-mentioned directions are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore cannot be understood as a limitation of the present disclosure. In addition, the terms "inside and outside" refer to the inside and outside of the corresponding structural contour. In addition, the terms "first", "second", etc. are only used to distinguish one element from another element, and do not have order and importance.
[0024] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0025] like Figures 1 to 5 As shown, the present disclosure provides a heating pipe assembly of a heating pipe network in a first aspect, the heating pipe assembly comprising a heating pipe 10 and an exhaust structure 20, wherein the heating pipe 10 is used to transport a heating medium, the heating pipe 10 comprises a curved section 100 curved in a direction away from the ground, an exhaust port 110 communicating with the interior of the curved section 100 is provided on the curved section 100, and the exhaust port 110 is located at the highest point of the curved section 100. The exhaust structure 20 comprises an exhaust pipe 200 and an exhaust valve 300, a first end of the exhaust pipe 200 is connected to the exhaust port 110, a second end of the exhaust pipe 200 extends in a direction close to the ground and is connected to the exhaust valve 300, and an outer surface of the exhaust pipe 200 is at least partially in contact with an outer surface of the curved section 100, so that heat exchange can be performed between the curved section 100 and the exhaust pipe 200.
[0026] Through the above technical solution, the bending section 100 is provided in the heating pipe 10, so that the gas mixed in the heating liquid in the heating pipe 10 can be gathered at the highest point of the bending section 100. The exhaust port 110 is provided at the highest point of the bending section 100, so that the gas can be discharged from the exhaust port 110 to the exhaust pipe 200. When exhaust is required, the exhaust valve 300 of the exhaust structure 20 is opened, so that the gas can be discharged from the exhaust valve 300 through the exhaust pipe 200, thereby reducing or avoiding the gas blockage caused by the gas in the heating pipe 10 for a long time or the damage of the heating pipe 10 caused by the gas hammer.
[0027] The present disclosure fits the outer surface of the exhaust pipe 200 at least partially with the outer surface of the curved section 100, so that heat exchange can be performed between the curved section 100 and the exhaust pipe 200. Since the curved section 100 transports heating liquid, the heat of the heating liquid can be transferred to the pipe wall of the curved section 100 and the pipe wall of the exhaust pipe 200 in turn, thereby continuously heating the gas and part of the dead water in the exhaust pipe 200, thereby avoiding the blockage of the exhaust pipe 200 caused by the condensation of the dead water in the outdoor low temperature environment. The technical solution provided by the present disclosure does not need to set a special electric heating device or other heating device outside the exhaust pipe 200 to heat the exhaust pipe 200, but directly uses the heating liquid in the heating pipe 10 to heat the exhaust pipe 200, thereby achieving the effect of cold and freezing protection, reducing power consumption, and achieving the purpose of energy saving.
[0028] It should be noted that the heating liquid can be water or a mixed liquid consisting of water and other liquids, and the present disclosure does not make any specific limitation on this.
[0029] like Figure 2 As shown, in some optional embodiments, the exhaust pipe 200 includes an inclined section 210 and an extension section 220 that are connected to each other, and one end of the inclined section 210 away from the extension section 220 is connected to the exhaust port 110, and an angle α between the axis of the inclined section 210 and the axis of the curved section 100 where the exhaust port 110 is located is less than 90°, and the exhaust valve 300 is arranged at the end of the extension section 220 away from the inclined section 210, and the outer surface of the extension section 220 is in contact with the surface of the curved section 100.
[0030] After the inclined section 210 of the exhaust pipe 200 is connected to the exhaust port 110, by setting the angle of the axis at the curved section 100 where the exhaust port 110 is located to be less than 90°, the end of the inclined section 210 close to the extension section 220 (that is, the end of the inclined section 210 away from the exhaust port 110) can be closer to the curved section 100, thereby reducing the space gap between the portion of the inclined section 210 located outside the curved section 100 and the curved section 100, so that the distance required for the heat of the curved section 100 to be transferred to the portion of the inclined section 210 located outside the curved section 100 is shorter, and the heat loss is less, so that the medium in the portion of the inclined section 210 located outside the curved section 100 can also be heated.
[0031] like Figures 1 to 4 As shown, in some optional embodiments, the curved section 100 includes a horizontal portion 102 and two vertical portions 101 respectively located on both sides of the horizontal portion 102, the horizontal portion 102 and the two vertical portions 101 form a U-shape with an opening facing the ground, the exhaust port 110 is opened on a side of the horizontal portion 102 away from the ground, and the outer surface of the horizontal portion 102 and the outer surface of one of the vertical portions 101 are both in contact with the outer surface of the exhaust pipe 200.
[0032] The openings of the two vertical parts 101 facing the ground are used to connect with other heating pipe sections in the heating pipe 10, so that the curved section 100 can be connected in series in the heating pipe 10. Since the horizontal part 102 is arranged horizontally, the axis of the entire horizontal part 102 is horizontal, and the height of any position on the side of the horizontal part 102 away from the ground is the same, and the side of the horizontal part 102 away from the ground is the highest point of the curved section 100. The exhaust port 110 can be arranged at any position on the side of the horizontal part 102 away from the ground, and the exhaust port 110 can be located at the highest point of the curved section 100, thereby reducing the difficulty of confirming and measuring the highest point of the curved section 100, and the exhaust port 110 can be arranged either at the end position close to the horizontal part 102 or at the middle position of the horizontal part 102, so that the position of the exhaust port 110 has more options to adapt to the installation position of the curved section 100 in the heating pipe assembly, for example, avoiding other environmental structural parts near the curved section 100.
[0033] It should be noted that, when the curved section 100 includes a horizontal portion 102 and two vertical portions 101 located on both sides of the horizontal portion 102 , the axis of the curved section 100 where the exhaust port 110 is located is the axis of the horizontal portion 102 .
[0034] like Figure 2As shown, in some optional embodiments, the inclined section 210 is inserted into the exhaust port 110 and fixedly connected to the curved section 100, and the depth of the inclined section 210 inserted into the exhaust port 110 is less than the wall thickness of the curved section 100. In the exhaust port 110, the height of one end of the inclined section 210 inserted into the exhaust port 110 is higher than the height of the medium channel inside the curved section 100 of the exhaust port 110, so that the gas can be more easily gathered and enter the exhaust port 110 and the exhaust pipe 200.
[0035] like Figure 2 As shown, in some optional embodiments, the end surface of the inclined section 210 inserted into the exhaust port 110 is a plane parallel to the horizontal plane. Setting the end surface as a plane can reduce the influence of the end surface of the inclined section 210 on the gas flow direction.
[0036] like Figure 1 and Figure 3 As shown, in some optional embodiments, the heating pipe assembly includes a plurality of pipe clamps 400 , and the plurality of pipe clamps 400 are arranged at intervals along the extension direction of the exhaust pipe 200 , and the exhaust pipe 200 is fixed to the curved section 100 by the plurality of pipe clamps 400 .
[0037] The pipe clamp 400 can be provided to fix the exhaust pipe 200 so that the exhaust pipe 200 can always be kept in contact with the outer surface of the curved section 100 .
[0038] It should be noted that the pipe clamp 400 may be a pipe clamp 400 of any structural form, such as a C-shaped pipe clamp 400 and a U-shaped pipe clamp 400, and the present disclosure does not make any specific limitation on this.
[0039] like Figure 3 , Figure 4 and Figure 5 As shown, in some optional embodiments, the heating pipe assembly further includes an insulation layer 500, which is coated on the outside of the curved section 100 and the exhaust pipe 200. The coating insulation layer 500 can insulate the curved section 100 and the exhaust pipe 200 to improve the heat exchange effect of the curved section 100 on the exhaust pipe 200.
[0040] It should be noted that if Figure 3 and Figure 4 As shown, the exhaust valve 300 is located outside the insulation layer 500 to facilitate operators to operate and control the exhaust valve 300, while allowing the exhausted gas to directly enter the ambient air.
[0041] like Figure 5As shown, in some optional embodiments, the thermal insulation layer 500 includes at least a first thermal insulation layer 510 and a second thermal insulation layer 520. The first thermal insulation layer 510 can be coated on the outside of the curved section 100 and the exhaust pipe 200, and the second thermal insulation layer 520 can be coated on the outside of the first thermal insulation layer 510 to improve the thermal insulation effect. In addition, the second thermal insulation layer 520 covers the seam of the first thermal insulation layer 510 to further improve the sealing of the coating, reduce the heat loss from the seam of the first thermal insulation layer 510, and further improve the thermal insulation effect.
[0042] In some optional embodiments, the thermal insulation layer 500 is aluminum silicate fiber felt. The aluminum silicate fiber felt can have the characteristics of low thermal conductivity, good thermal insulation performance, light weight and elasticity. When the aluminum silicate fiber felt is wrapped around the curved section 100 and the exhaust pipe 200, under the elastic effect of the aluminum silicate fiber felt, part of the aluminum silicate fiber felt can fill the gap in the wrapped space formed by the wrapping, so as to achieve a better thermal insulation effect.
[0043] Of course, in other embodiments, the thermal insulation layer 500 may also be a rock wool thermal insulation layer 500 made of rock wool or a rubber-plastic thermal insulation layer 500 made of rubber-plastic.
[0044] In a second aspect, the present disclosure further provides a heating pipe network, which includes the above-mentioned heating pipeline assembly.
[0045] In some optional embodiments, a plurality of curved sections 100 may be arranged at intervals on the heating pipe 10 of the heating network, and an exhaust structure 20 may be provided on each curved section 100 , or an exhaust structure 20 may be provided on each curved section 100 and covered with an insulation layer 500 .
[0046] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0048] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
