Description

Technical Field

[0001] The utility model belongs to the technical field of heating boiler pipeline installation, and specifically relates to a pipeline docking device for heating boiler installation. Background Art

[0002] In the heating system, the boiler is one of the core equipment, and the pipes are responsible for transporting hot water or steam to each room for heating. Pipe docking is a key step in the installation process of the heating system. If the docking is not tight, it will cause problems such as heat loss and water leakage, affecting the heating effect and system stability.

[0003] Traditional pipe docking methods usually use threaded connection, welding or flange connection. However, these methods have some limitations. Threaded connection requires high installation accuracy and may become loose after long-term use; welding connection requires professional welding skills and is difficult to disassemble and repair once welded; flange connection requires additional sealing gaskets, which are prone to gasket aging or leakage.

[0004] At the same time, the existing pipeline docking device needs a corresponding docking device to be used. If the conduit and the docking device do not match, it will be very troublesome to install, and in serious cases, it will lead to failure to install.

[0005] To this end, we have proposed a pipe docking device for heating boiler installation, which can not only simplify the installation steps and improve the subsequent installation and disassembly, but also adapt to the docking of pipes of different sizes and improve the use effect. Utility Model Content

[0006] The purpose of the utility model is to provide a pipe docking device for heating boiler installation, which can not only simplify the installation steps and improve the subsequent installation and disassembly, but also adapt to the docking of pipes of different sizes and improve the use effect.

[0007] The technical solutions adopted in this utility are as follows:

[0008] A pipe docking device for installing a heating boiler, comprising a first pipe and a second pipe, a docking assembly is arranged between the first pipe and the second pipe, and a first conical sealing connection block communicating with the first pipe and the second pipe is arranged on one side close to each other;

[0009] The docking assembly includes a hollow tube, and shells for allowing the first pipe and the second pipe to enter are arranged on both sides of the hollow tube. A conical cavity is opened inside the shell, and the inner wall of the conical cavity matches the first conical sealing connection block. An elastic rubber sealing ring is arranged at the entrance of the shell, and the first pipe and the second pipe are connected to the shell through a fixing assembly.

[0010] Furthermore, the first conical sealing connection block on the first pipe is wider on the left and narrower on the right.

[0011] Furthermore, the tapered cavity is wider on the left and narrower on the right.

[0012] Furthermore, a first rubber layer is provided on the outer side of the first conical sealing connection block, and a second rubber layer is provided on the inner wall of the conical cavity.

[0013] Furthermore, the fixing assembly includes a first threaded hole formed on the shell and a second threaded hole formed on the first pipe, and bolts are threadedly provided on the first threaded hole and the second threaded hole.

[0014] Furthermore, a through hole is provided in the middle of the elastic rubber sealing ring.

[0015] The technical effects achieved by this utility model are:

[0016] First, the first pipe and the second pipe are respectively inserted into the tapered cavities on the two shells. When inserting, they first pass through the elastic rubber sealing ring. At this time, the elastic rubber sealing ring will be deformed, thereby enlarging the first pipe and the second pipe to enter the tapered cavity. Then push again until the inclined surface of the first tapered sealing connection block fits with the inclined surface inside the tapered cavity to achieve a sealing effect. Since the tapered cavity is tapered, its various surfaces have different diameters, so it can adapt to different first tapered sealing connection blocks, so it can adapt to the docking of different pipes. At the same time, due to the characteristics of the elastic rubber sealing ring, it can become larger or smaller, so that it can mechanically seal different entering pipes. When the first pipe and the second pipe enter the tapered cavity for sealing, they are fixed by a fixing component to prevent them from shaking during work and causing leakage.

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0024] like Figure 1-4 As shown, the technical solution adopted by the utility model is specifically as follows: a pipe docking device for installing a heating boiler, comprising a first pipe 1 and a second pipe 2, a docking assembly is arranged between the first pipe 1 and the second pipe 2, and a first conical sealing connection block 3 communicating with the first pipe 1 and the second pipe 2 is arranged on one side close to each other;

[0025] The docking assembly includes a hollow tube 4, and shells 5 for the first pipe 1 and the second pipe 2 to enter are arranged on both sides of the hollow tube 4. A conical cavity 11 is opened on the shell 5, and the inner wall of the conical cavity 11 matches the first conical sealing connection block 3. An elastic rubber sealing ring 6 is arranged at the entrance of the conical cavity 11, and the first pipe 1 and the second pipe 2 are connected to the shell 5 through a fixing assembly.

[0026] Its working principle is: first, the first pipe 1 and the second conduit are respectively inserted into the tapered cavity 11 on the two shells 5, and when inserting, they first pass through the elastic rubber sealing ring 6. At this time, the elastic rubber sealing ring 6 will be deformed, thereby enlarging the first pipe 1 and the second conduit to enter the tapered cavity 11, and then push again until the inclined surface of the first tapered sealing connection block 3 is in contact with the inclined surface inside the tapered cavity 11, so as to achieve a sealing effect. Since the tapered cavity 11 is tapered, its various surfaces have different diameters, so it can adapt to different first tapered sealing connection blocks 3, so it can adapt to the docking of different conduits. At the same time, due to the characteristics of the elastic rubber sealing ring 6, it can become larger or smaller, so that it can mechanically seal different entering pipes. When the first pipe 1 and the second pipe 2 enter the tapered cavity 11 for sealing, they are fixed by a fixing component to prevent them from shaking during work and causing leakage.

[0027] The first conical sealing connection block 3 on the first pipeline 1 is wider on the left and narrower on the right, and such a configuration enables the first pipeline 1 to match the first conical cavity 11 .

[0028] At the same time, the housing 5 is wider on the left and narrower on the right, so that it can match the first conical sealing connection block 3 for sealing.

[0029] For example, when the first pipe 1 drives the first conical sealing block to enter the conical cavity 11, the first conical sealing connection block 3 will not match the inner wall of the conical cavity 11. When the first pipe 1 is continued to be pushed so that the inclined surface of the first conical sealing connection block 3 fits the inclined surface of the conical cavity 11, it will not be pushed forward at this time to perform sealing. When docking large pipes, the distances between the first conical sealing connection blocks 3 inside the shell 5 are different, so that they can adapt to different pipes.

[0030] In order to make the fit seal more intimate, a first rubber layer is provided on the outer side of the first conical sealing connection block 3, and a second rubber layer is provided on the inner wall of the shell 5. When the first conical sealing connection block 3 enters the conical cavity 11, the first rubber layer and the second rubber layer are deformed and squeezed against each other, thereby achieving a sealing effect.

[0031] The elastic rubber sealing ring 6 is made of rubber and has a through hole 10 in the middle, so that the first pipe 1 or the second conduit can enter. When entering, the elastic rubber sealing ring 6 will be deformed, so that the through hole 10 becomes larger, so that the first pipe 1 or the second conduit can enter. When entering, the elastic rubber sealing ring 6 will fit tightly with the first pipe 1 and the second conduit, thereby sealing the entrance and improving the use effect.

[0032] like Figure 3 and Figure 4 As shown, the fixing assembly includes a first threaded hole 7 opened on the shell 5, and a second threaded hole 8 opened on the first pipe 1. Bolts 9 are threadedly arranged on the first threaded hole 7 and the second threaded hole 8, and are threadedly entered into the first threaded hole 7 and the second threaded hole 8 to lock them, thereby preventing subsequent shaking.

[0033] There are multiple groups of second threaded holes 8, and the multiple groups of second threaded holes 8 can be adapted to different pipelines.

[0034] There are eight first threaded holes 7 and second threaded holes 8 distributed on all sides, so that the fixing force can be uniform without uneven force.

[0035] When it is possible to choose, the utility model can also be fixed by a snap-on method, which includes a spring and a fixing pin. The fixing pin is driven by the elastic force of the spring to enter the first threaded hole 7 and the second threaded hole 8 for locking, so that installation and disassembly can be performed faster. The snap-on method belongs to the prior art and will not be described in detail here.

[0036] The working principle of the utility model is as follows: firstly, the first pipe 1 and the second pipe are respectively inserted into the tapered cavity 11 on the two shells 5, and when inserting, they first pass through the elastic rubber sealing ring 6. At this time, the elastic rubber sealing ring 6 will be deformed, thereby enlarging the first pipe 1 and the second pipe to enter the tapered cavity 11, and then push again until the inclined surface of the first tapered sealing connection block 3 is in contact with the inclined surface inside the tapered cavity 11, so as to achieve the sealing effect. Since the tapered cavity 11 is tapered, its various surfaces have different diameters, so that it can adapt to different first tapered sealing connection blocks 3, so that it can adapt to the docking of different pipes. At the same time, due to the characteristics of the elastic rubber sealing ring 6, it can become larger or smaller, so that it can mechanically seal different pipes entering. When the first pipe 1 and the second pipe 2 enter the tapered cavity 11 for sealing, they are fixed by the fixing assembly to prevent them from shaking during operation and causing leakage.

[0037] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
