Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating pipeline leakage prevention, in particular to a heating pipeline leakage prevention component. Background Art
[0002] Pipe heating is achieved by municipal thermal power plants burning coal in boilers, etc., and then transmitting the heat to indoor radiators through centralized pipes to achieve the purpose of heating. Since the heating pipes need to be transported from the thermal power plant to thousands of households, the heating pipes are connected by multiple pipes and transmitted to each household. Therefore, leakage may occur at the connection of multiple heating pipes. Traditional heating pipe connections are mostly connected by flanges and sealing rings. However, if the distance between the two sets of pipes is too large, when connecting them through flanges and sealing rings, the sealing rings may not be able to seal the two sets of heating pipes. Once used for a long time, leakage may occur. For this reason, we propose a heating pipe leak-proof component to solve the above possible problems. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-Figure 3In this embodiment: a heating pipe leakage prevention component includes a heating pipe body 1, there are two heating pipe bodies 1, and the outer rings of the two sets of heating pipe bodies 1 on the side close to each other are sleeved with a sleeve 3, the sleeve 3 can be moved to a position between the two sets of heating pipe bodies 1, the outer rings of the two sets of heating pipe bodies 1 are sleeved with fastening plates 2, and the two sets of fastening plates 2 on the side close to each other are provided with a second sealing ring 7, the two sets of second sealing rings 7 on the side close to each other are provided with a first sealing ring 6, the sleeve 3 and the heating pipe body 1 can be sealed by the first sealing ring 6 and the second sealing ring 7, and the two sets of fastening plates 2 are connected by bolts 4.
[0019] In this embodiment, the inner diameter of the sleeve 3 is slightly larger than the outer diameter of the heating pipe body 1, so the sleeve 3 can be easily put on the outer ring of the heating pipe body 1. The first sealing ring 6 is located in the gap between the sleeve 3 and the heating pipe body 1. The vertical section of the second sealing ring 7 is a right-angled trapezoid. The first sealing ring 6 and the second sealing ring 7 are both made of high-temperature resistant and corrosion-resistant materials, which can extend the service life and achieve a better sealing effect. The fastening plate 2 is evenly provided with multiple groups of mounting holes at the edge, and the mounting holes are slightly larger than the outer diameter of the bolts 4, so the bolts 4 can be easily passed through the mounting holes opened in the fastening plate 2. The bolts 4 pass through the mounting holes opened in the left fastening plate 2 and pass out from the mounting holes opened on the right fastening plate 2. The outer ring of the bolt 4 located on the right side of the right fastening plate 2 is provided with a nut 5 matching it. By rotating the nut 5, the two groups of fastening plates 2 can be moved to positions close to each other through the bolts 4.
[0020] The working principle and use process of the utility model: the heating pipe leakage prevention component is used when the distance between two groups of heating pipes is too large, such as when the heating pipes are repaired and the damaged ends need to be cut off. At this time, when they are connected by general means, leakage may occur after long-term use. At this time, the fastening plate 2 can be put on the outer ring of one heating pipe first, and then the sleeve 3 can be put on the heating pipe, and the other fastening plate 2 can be put on the outer ring of the other heating pipe. Then, the fastening plate 2 can be put on the outer ring of the other heating pipe. The sleeve 3 is moved to the position between the two groups of heating pipes, and then the bolt 4 can be passed from the left fastening plate 2 to the right fastening plate 2, and the nut 5 can be rotated on the bolt 4 and tightened. At this time, the two groups of fastening plates 2 will move closer to each other, and the first sealing ring 6 can be squeezed into the gap between the sleeve 3 and the heating pipe body 1, and with the squeezing of the second sealing ring tube 7, the sealing effect can be achieved, and the sleeve 3 and the fastening plate 2 can be prevented from moving, thereby preventing leakage from occurring at the connection of the heating pipe body 1.
