Description

Technical Field

[0001] The utility model relates to the field of flange forgings, in particular to a flange forging of a tee joint. Background Art

[0002] A tee is a type of pipe fitting primarily used to change the direction of fluid flow and is typically used where a main pipeline branches out. A tee is a common connector in piping systems, used to connect three pipes or split a single pipe into two. It's commonly used in various fluid piping systems. A tee has flange forgings at each end, securing the pipe connection and ensuring stability.

[0003] The flange forging of the tee joint has mounting holes on the flange plate. The mounting holes on the flange plate are used to fit the flange at the end of the pipe for installation and fixation, so that the pipe and the tee joint are connected together and can then be used. However, the flange forging of the existing tee joint only has mounting holes on the flange plate, which can only be used to install pipes with flanges at the ends. Pipes with threaded ends cannot be connected to the tee joint, resulting in poor adaptability of the tee joint. At the same time, the flange forging of the tee joint does not have a sealing structure. After the pipes are connected, it is very easy to have a poor sealing line and leakage, resulting in poor performance. Utility Model Content

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand and connect, the present invention is further explained below in conjunction with specific implementation methods.

[0018] like Figures 1-4 The figure shows a flange forging for a three-way joint, comprising a connecting pipe 1. A connecting flange plate 2 is fixedly mounted on the upper end of the connecting pipe 1. A supporting boss 3 is provided inside the connecting pipe 1. The connecting flange plate 2 is provided with an arcuate mounting hole 4. Connecting screw grooves 5 are provided on the inner sides of the connecting flange plate 2 and the connecting pipe 1. A sealing assembly 6 is provided on the connecting flange plate 2. The connecting pipe 1 and the connecting flange plate 2 are integrally formed. The arcuate mounting holes 4 are arranged in an annular array on the connecting flange plate 2. An annular groove 7 is provided on the connecting flange plate 2, located inwardly of the arcuate mounting holes 4. The sealing assembly 6 is mounted in the annular groove 7 on the connecting flange plate 2, with the upper surface of the sealing assembly 6 being higher than the upper surface of the connecting flange plate 2.

[0019] When installing a tee joint using a flange forging, the installation method is selected according to the type of connection part at the pipe end. When the pipe end is a threaded joint, the pipe end is connected to the connecting pipe 1 and the connecting flange plate 2 using the threaded joint until the pipe threaded joint contacts the supporting boss 3. After all pipes are connected in this manner, it can be used. When the pipe end is a flange, the flange is attached to the connecting flange plate 2, and the flange of the pipe end contacts the sealing assembly 6. Bolts are inserted through the holes in the flange of the pipe end and the arc-shaped mounting holes 4 on the connecting flange plate 2. Nuts are installed at the ends of the bolts to secure the connecting flange plate 2 to the flange of the pipe end. During this process, the arc-shaped mounting holes 4 ensure that the holes are aligned, avoiding hole position deviation and ensuring the normal connection. At the same time, after the pipes are connected, the sealing assembly 6 is squeezed, which can achieve a sealing effect and ensure the sealing of the pipes after connection. When the tee joint is connected to the pipe and put into use, the material in the main pipe passes through the tee joint diversion channel into the two branch pipes, thereby achieving the effect of changing the flow direction and diverting the flow.

[0020] It should be noted that by opening an arc-shaped mounting hole 4 on the connecting flange plate 2 and using the arc-shaped mounting hole 4 to install and connect the relevant pipelines, the arc-shaped mounting hole 4 can effectively align the holes on the flanges at the end of the relevant pipelines during the installation process, preventing the normal connection of the bolts due to hole position deviation, thereby ensuring the effective connection between the flange forging and the pipeline end flange, and providing a connecting screw groove 5 in the connecting pipeline 1 and the connecting flange plate 2, so that the flange forging can also be connected to the pipeline with the threaded end, thereby improving the connection adaptability of the entire tee joint.

[0021] According to the above embodiment, the sealing assembly 6 includes a fixed connecting column 601, a supporting and tightening spring 602, an annular rubber sealing strip 603, and a spring clamping connecting block 604. The fixed connecting column 601 is fixedly installed in the annular groove 7 on the connecting flange plate 2, and the fixed connecting columns 601 are distributed in an annular array in the annular groove 7. The annular rubber sealing strip 603 is fixedly connected to the spring clamping connecting block 604, and the spring clamping connecting block 604 is distributed in an annular array on the annular rubber sealing strip 603. The lower half of the annular rubber sealing strip 603 is located in the annular groove 7 on the connecting flange plate 2. The lower end of the supporting and tightening spring 602 is sleeved on the fixed connecting column 601, and the upper end of the supporting and tightening spring 602 is connected to the spring clamping connecting block 604.

[0022] When installing the sealing assembly 6, the support spring 602 is connected to the spring clamping connection block 604 on the annular rubber sealing strip 603, so that the support spring 602 and the spring clamping connection block 604 are relatively fixedly connected. Then, the annular rubber sealing strip 603 is set into the annular groove 7 on the connecting flange plate 2, so that the lower end of the support spring 602 is sleeved onto the fixed connection column 601, thereby completing the installation and installation of the sealing assembly 6. During the use of the sealing assembly 6, the flange at the end of the pipeline is connected to the connecting flange plate 2. As the bolts and nuts are tightened, the connecting flange plate 2 and the flange at the end of the pipeline are fitted together. The annular rubber sealing strip 603 is forced to move in the annular groove 7 and compress the support spring 602, causing the annular rubber sealing strip 603 to give way. When the connection is completed, under the elastic action of the support spring 602, the annular rubber sealing strip 603 is in close contact with the flange at the end of the pipeline, thereby ensuring the sealing during use.

[0023] It should be noted that an annular groove 7 is opened on the connecting flange plate 2, and a sealing assembly 6 is arranged in the annular groove 7. When the relevant pipeline is installed on the flange forging through the flange, the supporting and tightening spring 602 plays a supporting and tightening role on the annular rubber sealing strip 603, thereby improving the connection sealing of the tee joint. At the same time, during the installation process, the annular rubber sealing strip 603 can enter the annular groove 7 without affecting the normal connection between the pipeline end flange and the flange forging.

Relevant personnel in this field can make connections based on the above content. The above content does not limit the present invention. The above embodiments and description describe the basic principles and features of the present invention. Under the premise of being consistent with the concept of the present invention, the present invention can also be subjected to various changes and improvements, and these improvements should fall within the scope of protection claimed by the present invention.
