Technical Field

[0001] This utility model relates to the field of heating pipeline technology, specifically a heating pipeline inlet sealing device. Background Technology

[0002] Heating pipelines, also known as heating networks, are pipe systems used to transfer heat energy. They deliver heat energy generated by boilers, in the form of steam or hot water, to indoor heating equipment to meet production and living needs. A heating pipeline system consists of multiple heating pipes that originate from heat sources (such as boiler rooms, direct-fired turbine rooms, heating centers, etc.) and lead to the building's heating inlet, forming a network. The media in heating pipelines are mainly of two types: hot water and steam. When construction is halted on heating pipelines, the pipe ends need to be sealed to prevent water or debris from entering the pipes. Currently, the practice is to wrap the pipe openings with plastic sheeting and secure them with wire. However, plastic sheeting is easily damaged over time and is not easy to use. Therefore, a pipe opening sealing device for heating pipelines is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a pipe end sealing device for heating pipelines, in order to solve the problem mentioned in the background art that when construction of heating pipelines is stopped, it is necessary to seal the pipe ends to prevent water or debris from entering the pipeline.

[0019] Example

[0020] In existing technologies, when construction is stopped on heating pipelines, the pipe ends need to be sealed to prevent water or debris from entering the pipeline. The current practice is to wrap the pipe openings with plastic sheeting and secure them with wire. However, plastic sheeting is prone to damage over time and is not easy to wrap properly.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a pipe sealing device for a heating pipeline, including a cover plate 2 installed at one end of the main body 1 of the heating pipeline, a protective cover 3 fixedly installed on one side of the cover plate 2, a sealing ring 4 fixedly installed on the inner wall of the protective cover 3, a sealing gasket 5 fastened to the inner wall of one side of the cover plate 2, a fixing block 6 fixedly installed on one side of the cover plate 2, a sealing plug 7 fixedly installed at one end of the fixing block 6 and fastened to the inner wall of the cover plate 2, a pull block 8 fixedly installed on the outer side of the sealing plug 7, and a fastening structure fixedly installed on one side of the cover plate 2. When sealing the main body 1 of the heating pipeline, the cover plate 2 is installed on one side of the main body 1 of the heating pipeline, and the protective cover 3 covers the outer side of the main body 1 of the heating pipeline. The protective cover 3 is provided with a sealing ring 4 inside, and the sealing ring 4 covers the outer side of the main body 1 of the heating pipeline, thereby sealing the main body 1 of the heating pipeline and preventing impurities from entering the interior of the main body 1 of the heating pipeline.

[0022] The fastening structure includes a fixing rod 9, which is fixedly installed on one side of the cover plate 2. A bidirectional threaded rod 10 is rotatably mounted inside the fixing rod 9. A handle 11 is fixedly mounted at one end of the bidirectional threaded rod 10. Two sliders 12 are slidably mounted inside the fixing rod 9. Two hinge seats 13 are fixedly mounted on the outer sides of each slider 12. Support rods 14 are hingedly connected to the outer sides of each hinge seat 13. A first connector 15 is fixedly connected to one end of each support rod 14, and a second connector 16 is fixedly mounted on the top of each support rod 14. The first connector 15 and the second connector 16 are hinged together. When the cover plate 2 is installed at one end of the heating pipe body 1, the fixing rod 9 on one side of the cover plate 2 inserts into the interior of the heating pipe body 1. Rotating the handle 11 causes the bidirectional threaded rod 10 to rotate, thereby causing the two sliders 12 to move towards each other. This causes the support rod 14 to abut against the inner wall of the heating pipe body 1, thus fixing the cover plate 2.

[0023] A groove is provided on one side of the cover plate 2, and one side of the sealing plug 7 is fastened inside the groove, thereby securing one side of the cover plate 2 with the sealing plug 7.

[0024] A groove is provided on the other side of the cover plate 2, and the sealing gasket 5 is embedded in the groove, which facilitates the installation and removal of the sealing gasket 5. The sealing gasket 5 seals the cover plate 2 and the main body of the heating pipe 1.

[0025] The fixed rod 9 has a groove inside, the slider 12 is slidably installed inside the groove, and the support rod 14 is slidably installed on the outside of the fixed rod 9 through the slider 12.

[0026] The slider 12 has a threaded hole inside, and the bidirectional threaded rod 10 passes through the threaded hole. By rotating the bidirectional threaded rod 10, the slider 12 is driven to slide.

[0027] The working principle or structural principle is as follows: When sealing the main body 1 of the heating pipe, the cover plate 2 is installed on one side of the main body 1 of the heating pipe, and the protective cover 3 covers the outside of the main body 1 of the heating pipe. The protective cover 3 is equipped with a sealing ring 4, which covers the outside of the main body 1 of the heating pipe, thereby sealing the main body 1 of the heating pipe and the protective cover 3. At the same time, the fixing rod 9 on one side of the cover plate 2 is inserted into the interior of the main body 1 of the heating pipe. Then, the sealing plug 7 is separated from one side of the cover plate 2. The rotating handle 11 is rotated, which drives the bidirectional threaded rod 10 to rotate. The bidirectional threaded rod 10 causes the two sliders 12 to move in opposite directions. The outer side of the sliders 12 is hinged to the support rod 14 through the hinge seat 13, so that the support rod 14 abuts against the inner wall of the main body 1 of the heating pipe, thereby fixing the cover plate 2 and sealing the main body 1 of the heating pipe, preventing impurities from entering the interior of the main body 1 of the heating pipe.

[0028] Those skilled in the art will understand that the features described in the various embodiments and / or claims of this utility model can be combined or combined in various ways, even if such combinations or combinations are not explicitly described in this utility model. In particular, the features described in the various embodiments and / or claims of this utility model can be combined or combined in various ways without departing from the spirit and teachings of this utility model.
