Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel tees, and particularly relates to an embedded inner-lined stainless steel sealed tee. Background Technique

[0002] In the field of modern industrial fluid control, the reliability and durability of pipeline connectors are crucial. With the progress of technology and the improvement of industrial standards, the inner-lined stainless steel sealed tee, as an efficient and reliable pipeline connection component, has gradually become the focus of attention in many industries.

[0003] The inner-lined stainless steel sealed tee is a pipeline connector with a special design, which combines the corrosion resistance of stainless steel materials and the multi-directional flow characteristics of tee pipe fittings. The stainless steel inner lining provides excellent chemical stability and can maintain its physical and chemical properties unchanged in harsh working environments for a long time. At the same time, the tee structure allows the fluid to be diverted in different directions, meeting the requirements of complex pipeline systems.

[0004] Although the existing inner-lined stainless steel sealed tees perform well in many industrial applications, they still have some deficiencies. The existing tees can only be used by connecting and fixing with the existing connection parts at the end of the pipeline, and it is impossible to insert a tee in the middle of a main pipeline. If a tee needs to be added in the middle of the pipeline to change the pipeline, the entire section of the pipeline needs to be replaced with a pipeline that can insert a tee and has connection parts. For large, complex pipelines or pipelines with heavy mass, it is very time-consuming and laborious to replace them in this way, so it is not convenient for daily implementation. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides an embedded inner-lined stainless steel sealed tee.

[0006] The technical solution of the utility model is: it includes a pipe body, a fixing ring arranged on the pipe body, and a cutting assembly movably arranged in the pipe body and used for cutting the pipeline; an installation disk for clamping with the fixing ring is arranged on the cutting assembly; at least one pin hole is arranged on the installation disk, a plug pin is correspondingly arranged on the side wall of the fixing ring, and a transverse air bag rod for driving the plug pin to be inserted into the pin hole is arranged on the fixing ring, and a vertical air bag rod with one end communicated with the transverse air bag rod and the other end contacting the pipeline.

[0007] Explanation: By the cutting assembly detachably arranged inside the fixing ring, a hole is cut in the pipeline where the pipeline needs to be inserted before embedding. For large, complex pipelines or pipelines with heavy mass, the tee joint can be easily added without replacing the pipeline separately, which saves time and effort.

[0008] Further, the cutting assembly includes a rotating motor disposed at the bottom of the mounting disk, a curved rod disposed on the output shaft of the rotating motor, a driving member disposed at the bottom of the curved rod, and a saw blade fixedly connected to the output shaft of the driving member at the center.

[0009] Explanation: The rotating motor drives the curved rod to rotate, driving the circular motion of the saw blade. The driving member provides power for the saw blade to make the saw blade rotate for cutting. After cutting a hole to be embedded in the pipeline, the cutting assembly is disassembled. This design facilitates the elastic insertion tube to be embedded in the hole of the main pipeline and facilitates the insertion of a tee at any position of the pipeline.

[0010] Further, the fixing ring is sleeved on the side wall of the pipe body, and the pipe body has holes for the pins to pass through.

[0011] Explanation: The fixing ring can ensure a more stable connection between the pipe body and the cutting assembly. Through the pin mechanism, quick clamping and disassembly can be achieved. When using the cutting assembly to cut a hole in the pipeline, the outer wall of the pipeline needs to be pressed. During cutting, the vertical airbag rod will be squeezed and contracted. At this time, the horizontal airbag rod connected to the vertical airbag rod will be inflated and expanded, pushing out the pin on the fixing ring and inserting it into the pin hole. When the cutting assembly finishes cutting the hole, the cutting assembly is withdrawn. At this time, the pressure on the vertical airbag rod is reduced, and the vertical airbag rod automatically rebounds and resets. The horizontal airbag rod contracts to retract the pin, releasing the plug-in fixation. Using this design for clamping and fixing is not only simple and convenient but also has a good stabilizing effect.

[0012] Further, the fixing ring is provided at the bottom end of the pipe body, and an elastic insertion tube is provided at the bottom end of the fixing ring. A reinforcing piece and a sealing ring are sleeved on the elastic insertion tube.

[0013] Explanation: The elastic insertion tube is used to embed the pipeline, and the reinforcing piece and the sealing ring can seal the connection between the elastic insertion tube and the hole.

[0014] Further, sheet materials for fixing are provided on both sides of the pipe wall of the pipe body, and tightening bands are provided on the sheet materials.

[0015] Explanation: The tightening bands fasten the sheet materials provided on both sides of the pipe wall of the pipe body to fix the position during cutting to avoid loosening. The position to be inserted into the pipeline can be temporarily retained and previewed. When the elastic insertion tube is not fully sealed during embedding, it can be fixed to prevent falling off. The tightening bands can be applied to pipe bodies of various shapes, with strong practicability.

[0016] Further, magnetic points that can mutually correspond and adsorb are respectively provided on the inner wall of the fixing ring and the outer wall of the mounting disk.

[0017] Explanation: The magnetic points that mutually correspond and adsorb on the inner wall of the fixing ring and the outer wall of the mounting disk can instantaneously fix the cutting assembly, making the insertion of the pin into the pin hole more convenient.

[0018] Further, a fixing rod is provided at the bottom of the curved rod located at the axis position of the output shaft, and a suction cup is rotatably provided at the bottom of the fixing rod.

[0019] Explanation: The suction cup is used to fix the circular piece of the main pipe hole cut off to prevent it from falling into the main pipe; the connection between the fixing rod and the bottom of the curved rod is located at the axis position of the output shaft, which can avoid hindering the movement track of the curved rod, and the rotational connection between the fixing rod and the suction cup can avoid the influence of the rotation of the curved rod on the use of the suction cup.

[0020] The beneficial effects of the present utility model are as follows: The present utility model drives the curved rod to rotate through the rotating motor, drives the circular motion of the saw blade, provides power for the saw blade through the driving member, and makes the saw blade rotate and cut; then the cutting assembly is disassembled, and then the pipe body is embedded into the pipe hole. The fixing ring can ensure a more stable connection between the pipe body and the cutting assembly. The cutting assembly can be fixed through the pin mechanism, which can achieve quick clamping and disassembly, is simple and convenient, and has a good stabilizing effect; the elastic insertion pipe and the hole connection are sealed by using the reinforcing piece and the sealing ring, so as to realize the operation of adding a tee in the middle of the pipe. A tee joint is successfully added in the middle of the pipe, and there is no need to replace the whole section of the pipe; the flow direction of the pipeline is changed by using the embedded tee, which saves time and labor, and makes the pipeline transformation work simple and convenient.
