Description

Technical Field

[0001] This utility model relates to the field of tee pipe technology, specifically a double-sealed locking and fixing structure for tee pipes. Background Technology

[0002] With social development, tees play a vital role in numerous fields, especially in pipeline systems. Tees connect one pipe to two others, allowing fluids to be distributed, redirected, or merged in different directions and paths. They are widely used in industries such as chemical, petroleum, natural gas, building water supply and drainage, and HVAC. Their importance lies in their ability to construct complex and efficient pipeline networks, ensuring the normal operation of various industrial production and daily life facilities, and improving the efficiency and flexibility of fluid transmission.

[0003] When installing existing tee pipes, if hot-melt plastic fittings are used for splicing, the thickness of the connection between the tee pipe and fittings decreases after the hot-melt process. This also causes deformation at the connection, making the connection less secure and prone to leakage. If nut connections are used, waterproof tape needs to be filled at the connection, but this tape is prone to aging, leading to further leaks at the connection. Utility Model Content

[0004] The purpose of this utility model is to provide a double-sealed locking and fixing structure for a three-way pipe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-sealed locking and fixing structure for a three-way pipe, comprising a pipe fitting: an extension tube is provided at both ends and the middle of the top of the pipe fitting; a sealing ring is provided at the end of the outer surface of the extension tube away from the pipe fitting; a fastener is fitted on the outer surface of the extension tube; an anti-slip groove is provided on the outer surface of the fastener; an internal thread is provided on the inner surface of the fastener; and a limit ring is provided at the end of the outer surface of the extension tube near the sealing ring.

[0006] By adopting the above technical solution, when installing the tee pipe, the user will put the pipe on the extension pipe. Since the extension pipe is equipped with a sealing ring, the sealing ring will provide initial sealing. Then, the outer surface of the pipe will be connected to the tee pipe by fasteners, so that the tee pipe can connect the inner and outer walls of the pipe. The pipe will abut against the limiting ring for secondary sealing, and the fasteners will abut against the limiting ring for further sealing.

[0007] Preferably, the pipe fitting has connecting grooves at both ends and the top, the outer surface of the extension pipe near the end of the pipe fitting has an external thread, the inner wall of the connecting groove on the pipe fitting has a thread, and the pipe fitting is connected to the extension pipe through the external thread and the thread.

[0008] By adopting the above technical solution, the extension pipe is installed on the pipe fitting through external threads and internal threads. Users can replace the extension pipe with one of the corresponding size according to the size of the pipe, so that the tee pipe can be adapted to the pipe.

[0009] Preferably, an annular groove is formed on the outer surface of the extension tube at the end away from the fitting, and the size of the annular groove on the extension tube is adapted to the size of the sealing ring, and the extension tube is connected to the sealing ring through the annular groove.

[0010] By adopting the above technical solution, the sealing ring is sleeved on the extension pipe through the annular groove. When the pipe and the extension pipe are connected, the sealing ring can not only play an auxiliary fixing role, but also play a sealing role.

[0011] Preferably, the fastener has a circular hole at one end near the pipe, the size of the circular hole on the fastener is adapted to the size of the extension pipe, and the extension pipe is slidably connected to the fastener through the circular hole.

[0012] By adopting the above technical solution, the fastener is slidably connected to the extension pipe through the round hole, which facilitates the connection between the fastener and the pipe.

[0013] Preferably, the limiting ring abuts against the fastener, and the extension tube is engaged with the fastener via the limiting ring.

[0014] By adopting the above technical solution, when fasteners are connected to pipes, the limiting ring can prevent the fasteners from falling off the extension pipe, and when the fasteners abut against the limiting ring, it can also achieve a re-sealing effect.

[0015] Preferably, there are three extension tubes, and the three extension tubes are connected by a fitting.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The tee pipe double sealing and locking structure connects the pipe fitting to the pipeline through an extension pipe and is connected to the pipe fitting by fasteners through threads. It uses two connection methods to connect the tee pipe and the pipeline. The extension pipe is also equipped with a sealing ring to ensure the connection between the extension pipe and the pipeline is sealed. A limit ring is set between the fastener and the pipeline, and the pipeline abuts against the limit ring. The connection between the fastener and the pipeline can prevent the pipeline and the limit ring from separating, further improving the sealing performance between the tee pipe and the pipeline.

A limiting ring 7 is provided at the end of the outer surface of the extension pipe 2 near the sealing ring 3. When installing the three-way pipe, the user fits the pipe onto the extension pipe 2. Since the extension pipe 2 is provided with a sealing ring 3, a preliminary seal is achieved through the sealing ring 3. Then, the outer surface of the pipe is connected to the three-way pipe through the fastener 4, so that the three-way pipe can connect both the inner and outer walls of the pipe. The pipe abuts against the limiting ring 7 for a secondary seal, and the abutment between the fastener 4 and the limiting ring 7 provides a second seal.
