Description

Technical Field

[0001] The invention relates to the technical field of three-way pipes, in particular to a three-way pipe. Background Art

[0002] A tee is a pipe connector used to change the direction of a fluid. The tee has three openings, namely one inlet and two outlets, or two inlets and one outlet. It has T-shape and Y-shape, with equal-diameter openings and different-diameter openings. It is used at the confluence of three identical or different pipelines and is widely used in both household and industrial production.

[0003] In the prior art, when a pipeline needs to be temporarily blocked, especially when a branch pipe with a longer length on one side of a large tee pipe needs to be temporarily blocked, a circular plate with the same diameter as the pipeline is currently used for welding at the pipeline port. Moreover, when the pipeline wall or the pipeline port flange is damaged, such temporary blocking method will fail. The entire welding process takes a long time and is inefficient. It requires the use of construction tools such as welding machines and electric drills to complete. At the same time, it is not convenient to remove the welding structure after the blocking is cancelled, and the surface flange of the tee pipe will be damaged, thereby affecting the later use of the tee pipe.

[0004] To solve the above problems, we adopt a blocking mechanism to facilitate installation and disassembly. Summary of the invention

[0005] The first main purpose of the present invention is to provide a three-way pipe that can effectively solve the problem of the complicated blocking process of large-diameter three-way pipes.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a three-way pipe, characterized in that it includes a pipe body, an outer wall of the pipe body is respectively connected to an inlet pipe and two outlet pipes, the inlet pipe and the two outlet pipes are fixedly provided with flanges at one end away from the valve body, and a blocking mechanism can be provided at the connection of each flange, the blocking mechanism includes an annular posting plate, a rotating handle, a threaded rod, a conical block, an elastic rubber block, and a limiting block, a threaded hole is opened on the annular posting plate, a threaded rod is fixed at the bottom end of the rotating handle, the threaded rod is spirally inserted into the top of the annular posting plate and extends to the lower end of the annular posting plate, a conical block is installed at the lower end of the threaded rod, a limiting block is placed in the pipeline, an air bag is provided on the outside of the limiting block, an air inlet and outlet are provided on the air bag, the limiting block is fitted with the inside of the pipeline, an elastic rubber block is placed on the upper side of the limiting block, a cross steel plate is provided inside the elastic rubber block, a friction block is provided on the outside of the elastic rubber block, and the elastic rubber block will cling to the inner side of the pipeline under the extrusion of the conical block to achieve blocking.

[0007] Preferably, the annular post plate is provided with threaded holes.

[0008] Preferably, a limiting block is placed inside the pipeline, and air bags are arranged around it.

[0009] Preferably, the airbag is provided with air inlet and outlet holes.

[0010] Preferably, the elastic rubber block is made of rubber material, has a cross steel plate inside, and has a friction plate on the outer surface of the elastic rubber block.

[0011] Preferably, the bottom end of the threaded rod is inserted into the top wall of the conical block, and the threaded rod can rotate on the top wall of the conical block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The present invention provides a blocking mechanism, and uses a limiting block and a conical block part of the blocking mechanism to block the flange opening at the flange connection at one end of the two water outlet pipes, thereby temporarily blocking the branch pipe on one side of the tee pipe. The blocking mechanism is easy to disassemble, and the flange and the inner wall of the tee pipe will not be damaged during the disassembly process, and the later use of the tee pipe will not be affected. A plurality of threaded holes are provided on the annular plate, and bolts can be rotated and inserted into the threaded holes of the annular plate according to the number of flange through holes, thereby improving the impact resistance of the blocking mechanism.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features specified as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1-5As shown, a three-way pipe includes a valve body 1, and an inlet pipe and two outlet pipes are respectively connected to the outer wall of the valve body 1. The inlet pipe and the two outlet pipes are fixedly provided with flanges 3 at one end away from the valve body 1, and a sealing mechanism 4 is provided at the connection of each flange 3. The sealing mechanism 4 includes an annular plate 401, a threaded hole 405 is opened on the annular plate 401, and a rotating handle 402. A threaded rod 403 is fixed to the bottom end of the rotating handle 402. The threaded rod 403 is spirally inserted into the top of the annular plate 401 and extends to the lower end of the annular plate 401. A conical block 404 is installed at the lower end of the threaded rod 403. When a branch pipe with a longer length on one side of a large three-way pipe needs to be temporarily blocked, the threaded rod 403 with matching length can push the conical block 404 to the center of the three-way pipe, so that the pipe near the center of the three-way pipe can be blocked to prevent The flange of the pipe port is damaged or the pipe wall is damaged, resulting in failure of sealing. A limiting block 406 is placed in the pipe 2. The limiting block 406 fits inside the pipe. An elastic rubber block 407 is placed on the upper side of the limiting block 406. Under the extrusion of the conical block 404, it will fit tightly against the inner side of the pipe 2 to achieve sealing. By adopting the above technical solution, the rotating handle 402 is rotated to move the conical block 404 downward. The downward movement of the conical block 404 will squeeze the elastic rubber block 407. At this time, the elastic rubber block 407 forms a seal on the inside of the pipe. At this time, the branch pipe on one side of the tee is blocked. When disassembling, the rotating handle 402 is rotated. At this time, the conical block moves upward. After the conical block 404 is taken out, the elastic rubber block 407 and the limiting block 406 placed in the pipe can be directly taken out. This process will not cause damage to the inner wall and flange of the tee.

[0025] Specifically, a threaded hole 405 is provided on the annular plate 401. By adopting the above technical solution, the annular plate 401 and the end surface of the flange 3 are fitted together using bolts to enhance the pressure resistance of the sealing mechanism 4.

[0026] Specifically, a limiting block 406 is placed inside the pipe 2, and is surrounded by air bags 4061. The air bags are provided with air inlet and outlet holes 4062. By adopting the above technical solution, an elastic inflation tube in the prior art is used to connect the air inlet and outlet holes 4062 on the air bag 4061, and the limiting block 406 is placed in the pipe 2. The air bag 4061 is inflated, and the air bag 4061 fills the gap between the limiting block 406 and the pipe 2. The friction between the air bag 4061 and the pipe 2 is used to limit the movement of the limiting block 406. At this time, the elastic rubber block 407 is placed on the upper end of the limiting block 406 to prevent the conical block 404 from moving downward and driving the elastic rubber block 407 to move downward.

[0027] Specifically, the elastic rubber block 407 is made of rubber material, and is provided with a cross steel plate 4071 inside, and a friction plate 4072 is provided on the outer surface of the elastic rubber block. By adopting the above technical solution, the elastic rubber block 407 using rubber material can better seal the pipeline 2, and the use of the friction plate 4072 on the outer surface of the elastic rubber block 407 can make the elastic rubber block 407 better fit with the pipeline 2, and the cross steel plate 4071 can improve the strength of the elastic rubber block 407.

[0028] Specifically, the bottom end of the threaded rod 403 is inserted into the top wall of the pressing block 404 , and the threaded rod 403 can rotate on the top wall of the pressing block 404 .

[0029] By adopting the above technical solution, the bottom end of the threaded rod 403 can be rotatably inserted on the top wall of the pressure block 404. When the threaded rod 403 moves up and down, it can drive the pressure block 404 to move together, thereby realizing the contraction and squeezing of the elastic rubber block 407, and finally making the sealing mechanism 4 close to the inner wall of the flange 3 and the pipeline 2.

[0030] Working principle: When in use, the limiting block 406 is placed in the pipe 2, and the airbag 4061 is inflated. The airbag 4061 fills the gap between the limiting block 406 and the pipe 2, and the friction between the airbag 4061 and the pipe 2 is used to limit the movement of the limiting block 406. At this time, the elastic rubber block 407 is placed on the upper end of the limiting block 406 to prevent the cone block 404 from moving downward and driving the elastic rubber block 407 to move downward. Then, the elastic rubber block 407 and the cone block 404 are placed in the pipe 2 in turn, and the annular plate 401 is placed close to the pipe 2. The end face of flange 3 is fixed with bolts, and the rotating handle 402 is turned to move the conical block 404 downward. The downward movement of the conical block 404 will squeeze the elastic rubber block 407. At this time, the elastic rubber block 407 forms a seal on the inside of the pipeline. At this time, the branch pipe on one side of the tee pipe is blocked. When disassembling, the rotating handle 402 is rotated. At this time, the conical block moves upward. After the conical block 404 is taken out, the elastic rubber block 407 and the limiting block 406 placed in the pipeline can be directly taken out. This process will not cause damage to the inner wall of the tee pipe and the flange.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
