Description

Technical Field

[0001] The utility model relates to the field of pipeline connection, in particular to a municipal water heating pipeline connection structure. Background Art

[0002] In municipal engineering, the connection structure of water heating pipes is the key link to ensure the safe and efficient operation of the entire water heating system. At present, the common water heating pipe connection structures on the market mostly adopt traditional welding, flange connection or threaded connection. Although these connection methods meet the needs of pipe connection to a certain extent, they still have some shortcomings in practical applications.

[0003] First, the welding connection method is prone to thermal stress during the welding process, causing deformation or cracks in the pipeline, affecting the safety and service life of the pipeline. Secondly, although flange connection and threaded connection methods are easy to install, leakage problems are prone to occur at the connection, especially when it is in long-term operation and is subject to external pressure changes. In addition, these traditional connection methods also have problems such as high installation cost and difficult maintenance. Therefore, we need a municipal water and heating pipe connection structure to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a municipal water heating pipe connection structure, which solves the problems in the above-mentioned background technology.

[0006] A further technical solution of the utility model is that both ends of the sealing ring are rounded arc surfaces.

[0007] A further technical solution of the utility model is that a locking hoop is sleeved on the rotating sleeve.

[0008] A further technical solution of the utility model is that the connecting pipe and the rotating sleeve are made of corrosion-resistant alloy.

[0009] A further technical solution of the utility model is that the sealing element is made of highly elastic silicone rubber.

[0010] Beneficial effects of the utility model: The utility model has a simple structure, convenient operation and high safety: the connection piece is made of high-strength, corrosion-resistant alloy material to ensure that the connection structure has good mechanical properties and chemical stability; the high-performance sealing material filled in the sealing groove effectively prevents leakage at the connection. Low cost: the simple and practical design reduces the material cost and processing difficulty; the installation process is simple and quick, reducing the installation cost.

[0014] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0015] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of the present specification are only used to match the contents disclosed in the specification for people familiar with the technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present utility model, should still fall within the scope of the technical contents disclosed by the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in the present specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present utility model. The change or adjustment of the relative relationship, without substantial change of the technical contents, should also be regarded as the scope of the implementation of the present utility model.

[0016] Embodiment 1: Figure 1-Figure 2A municipal water and heating pipe connection structure is shown, which is characterized in that the device comprises: a connecting pipe 2, a cylindrical raised sealing ring 3 is provided in the middle of the connecting pipe 2, rotating sleeves 1 are sleeved at both ends of the connecting pipe 2, external threads are provided on the outer circles of the two ends of the connecting pipe 2, and internal threads are provided on the inner wall of the rotating sleeve 1. The connecting pipe 2 and the rotating sleeve 1 are threadedly matched, a sealing member 5 is provided on the inner wall of the sealing ring 3, both ends of the sealing ring 3 are rounded arc surfaces, a locking hoop 4 is sleeved on the rotating sleeve 1, the connecting pipe 2 and the rotating sleeve 1 are made of corrosion-resistant alloy, and the sealing member 5 is highly elastic silicone rubber. When we need to connect water and heating pipes, insert the two pipes to be connected into the matching connecting pipes 2 at the same time, so that the connection is in the position of the sealing ring 3, so that the sealing member 5 can further surround the connection to seal. After the position is set, rotate the rotating sleeves 1 at both ends to press the middle sealing ring 3. The inner diameter of the rotating sleeve 1 is slightly smaller than the outer diameter of the sealing ring 3. The strength of the rotating sleeve 1 will be greater than the sealing ring 3. There is a section without internal threads inside the rotating sleeve 1. This section will give an extrusion force to the sealing ring 3 during the rotation of the rotating sleeve 1 in the middle of the box, thereby further applying the extrusion force to the sealing member 5, and further sealing the connection between the two pipes. Finally, after the two rotating sleeves 1 are rotated into place, the two locking hoops 4 are locked to fix the connecting pipe 2, the rotating sleeve 1 and the two water and heating pipes.

[0017] The utility model has a simple structure, convenient operation and high safety: the connection parts are made of high-strength, corrosion-resistant alloy materials to ensure that the connection structure has good mechanical properties and chemical stability; the high-performance sealing material filled in the sealing groove effectively prevents leakage at the connection. Low cost: the simple and practical design reduces the material cost and processing difficulty; the installation process is simple and fast, reducing the installation cost. Easy maintenance: the connection structure is easy to disassemble and replace, reducing the difficulty and cost of maintenance.
