Description

Technical Field

[0001] The present application relates to the technical field of connectors, and specifically to a heating, ventilation and air conditioning (HVAC) pipe connector kit. Background Art

[0002] As an important part of building equipment, the development of HVAC pipes is closely linked to the progress of building technology. With the continuous development of the construction industry, HVAC pipe technology is also constantly innovating and improving. From early metal pipes to modern plastic pipes, composite material pipes, etc., the materials and processes of HVAC pipes have been continuously upgraded to meet the needs of different buildings and environments.

[0003] HVAC pipe connectors are key components for connecting HVAC pipes. They connect various parts of the pipe system tightly together through specific connection methods to form a complete fluid transportation channel.

[0004] For example, the patent with the publication number CN213206843U discloses a building HVAC pipe connector that is easy to disassemble and install. Through the setting of the sealing connection component, the tightness during the connection of HVAC pipes can be ensured, and during long-term use, the pipe connection can be tightened by tightening the adjusting end cover.

[0005] During the implementation of the above patent, there may be a situation where a large amount of fluid suddenly flows in. However, the common inflow of a large amount of fluid into the pipe will cause varying degrees of impact on the pipe. The long-term impact will lead to material fatigue, wear, and even rupture of the pipe and the connector, thus affecting the normal operation and safety of the system.

[0006] Therefore, it is necessary to provide a HVAC pipe connector kit to solve the above problems.

[0007] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0008] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a HVAC pipe connector kit that solves the problem of a large amount of fluid flowing into the pipe together, thereby causing varying degrees of impact on the pipe, and further leading to material fatigue, wear, and even rupture of the pipe and the connector.

Detailed Description of the Invention

[0033] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments may be combined with each other. The following will refer to the drawings and combine with the embodiments to detail this application.

[0034] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0035] As Figure 1 - Figure 2 shown, this application provides a heating and ventilation pipe joint kit, including two groups of housings 1. The interior of the housing 1 is a cavity, so as to protect the internal components from the external environment, thereby preventing external water vapor from invading;

[0036] Meanwhile, a plurality of fixing seats 2 are fixedly arranged outside the two sets of housing covers 1. Threaded holes are provided between the fixing seats 2, so that operators can fix them using bolts or the like, thereby fixing the two sets of housing covers 1 accordingly;

[0037] And a connecting pipe 6 is fixedly arranged inside the housing cover 1. The connecting pipe 6 is used to provide a flow channel for the fluid. At the same time, two sets of connectors 7 are fixedly arranged at both ends of the connecting pipe 6. Threads are provided inside the connectors 7 for convenient fixing. At the same time, pipes 3 are threadedly connected inside the two end connectors 7. The pipes 3 are used to transport the fluid to a designated position. And a sealing ring 8 is fixedly arranged at the connection between the pipe 3 and the connector 7. The sealing ring 8 is used to ensure the sealing performance of the connection and prevent fluid leakage;

[0038] The pipe 3 is connected to the connecting pipe 6 through two sets of connectors 7, thereby forming a complete fluid passage. At the same time, the operator locks the two sets of housing covers 1 to prevent external water vapor from invading the internal components;

[0039] As Figure 2 - Figure 4 shown, when a large amount of fluid flows into the pipe 3 together, in order to prevent the large amount of fluid from causing varying degrees of impact on the pipe 3, which may further lead to material fatigue, wear or even rupture of the pipe 3 and the joints, a control mechanism 4 is fixedly arranged at the middle position of the connecting pipe 6 inside the housing cover 1. The control mechanism 4 is used to regulate and control the flow of the fluid in the pipe 3;

[0040] The control mechanism 4 includes a cavity 41 fixedly arranged at the middle position of the connecting pipe 6. The cavity 41 is used to provide a buffering area for the fluid. At the same time, a plurality of buffer blocks 46 are fixedly arranged in the cavity 41. The buffer blocks 46 are used to buffer the fluid entering the cavity 41 to varying degrees;

[0041] And the buffer blocks 46 block and buffer at the entrance of the cavity 41 to form a first channel. At the same time, buffer blocks 46 are also fixedly arranged at the exit of the cavity 41 to form a second channel. And there is a certain height difference between the first channel and the second channel. Furthermore, a vertical buffer channel is formed between the first channel and the second channel to connect them, so as to achieve the purpose of buffering the fluid to varying degrees;

[0042] When the fluid flows into the cavity 41 through the pipe 3, the fluid will be buffered by the first channel and the second channel. At the same time, the vertical buffer channel can also buffer the impact of the fluid to varying degrees, thereby alleviating the impact of the fluid on the pipe 3;

[0043] At the same time, the upper end of the cavity 41 penetrates through the housing cover 1 and extends to the outside, and a sealing cover 44 is fixedly arranged at the top of the cavity 41. The sealing cover 44 is used to seal the cavity 41 to prevent fluid leakage;

[0044] And in order to further relieve and adjust the fluid flow rate, a pressing-down component 5 is arranged inside the cavity 41 on the buffer channel. The pressing-down component 5 includes a pin shaft 45 threadedly arranged on the sealing cover 44. At the same time, one end of the pin shaft 45 penetrates through the sealing cover 44 and extends into the cavity 41.

[0045] A packing 47 is fixedly arranged at the connection between the sealing cover 44 and the pin shaft 45. The packing 47 is used to fill the pin shaft 45 to prevent fluid from leaking through the gap between the pin shaft 45 and the sealing cover 44.

[0046] A hand wheel 43 is fixedly arranged at one end of the pin shaft 45 close to the sealing cover 44. The hand wheel 43 is used to provide an interface for manual operation by the staff. By rotating the hand wheel 43, the pin shaft 45 can be driven to move up and down, so as to control the opening and closing of the pressing-down component 5.

[0047] At the same time, one end of the pin shaft 45 extending into the cavity 41 is connected to a connection block (not shown in the figure) by a bearing. And a plurality of support columns 53 are fixedly arranged on the connection block (for reference Figure 4 ). At the same time, a mesh plate 52 is fixedly arranged at the bottom end of the support column 53. A plurality of small holes are formed in the mesh plate 52. The small holes are used for the fluid to pass through.

[0048] When it is necessary to further relieve the fluid flow rate, the operator can rotate the hand wheel 43 to drive the pin shaft 45 to move downward along the sealing cover 44 until the mesh plate 52 blocks the buffer channel, and then stop descending. At this time, the fluid flowing into the cavity 41 through the pipeline 3 will enter the vertical buffer channel. Thus, the mesh plate 52 moves downward to block the vertical buffer channel, and further forces the fluid to flow through the small holes on the mesh plate 52, so as to achieve the purpose of further relieving the fluid flow rate.

[0049] When it is not necessary to relieve, the hand wheel 43 can be rotated in the reverse direction to drive the pin shaft 45 to move upward along the sealing cover 44, so as to open the buffer channel, and thus the fluid can flow through the buffer channel.

[0050] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
