Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of three-way pipes, in particular to a three-way pipe with an anti-freezing and explosion-proof mechanism. Background Technique
[0002] A three-way pipe refers to a pipe joint with three openings, which is widely used in pipe networks for transporting liquids and gases.
[0003] Generally, a three-way pipe has one inlet and two outlets, or two inlets and one outlet. The use of a three-way pipe improves the diversity of pipeline transportation. However, since all three connection ports inside need to be used for circulation support, when blockage occurs inside, a large pressure will be generated, leading to its explosion. In addition, when facing a relatively cold external environment, due to the limited internal circulation space, freezing will occur, affecting the safety during its operation.
[0004] Therefore, we provide a three-way pipe with an anti-freezing and explosion-proof mechanism. Content of the Utility Model
[0005] The purpose of the utility model is to provide a three-way pipe with an anti-freezing and explosion-proof mechanism for the above-mentioned existing technical problems, so as to achieve the effect of improving the anti-freezing and explosion-proof performance of the device.
[0006] In view of this, the utility model provides a three-way pipe with an anti-freezing and explosion-proof mechanism, including a pipe body, and a fixed ring and an auxiliary ring installed on the inner wall. Fixed connection cylinders are installed on adjacent sides of the fixed ring and the auxiliary ring. A middle elastic pipe is arranged between the two fixed rings. Opposite sides of the middle elastic pipe are fixedly connected to the two fixed connection cylinders at the same time. An I-shaped guide rail is installed outside the middle elastic pipe. An arc-shaped sliding rod is slidably installed inside the I-shaped guide rail. The arc-shaped sliding rod extends outside the I-shaped guide rail, and sliding support rings are slidably connected to opposite ends of the I-shaped guide rail at the same time. The sliding support rings are installed on the inner wall of the pipe body. A fixed connection block is installed outside the arc-shaped sliding rod, and the fixed connection block is used for the movement of the arc-shaped sliding rod.
[0007] Preferably, one fixed ring, one auxiliary ring and one middle elastic pipe form a group for operation, and a group of the fixed ring, the auxiliary ring and the middle elastic pipe are installed inside each connection port of the pipe body.
[0008] Preferably, at least two I-shaped guide rails are installed outside the middle elastic pipe, fixed connection blocks are installed outside both arc-shaped sliding rods, and telescopic plates are slidably installed on the upper ends of both fixed connection blocks.
[0009] Preferably, a moving handle is installed on the upper ends of both telescopic plates at the same time, and the moving handle is used for the moving support of the fixed connection block.
[0010] Preferably, a moving groove is formed on the outer side of the pipe body, and the number of the moving grooves is the same as that of the telescopic plates. The telescopic plates are inserted into the moving grooves, and the moving handle is located on the outer side of the pipe body.
[0011] Preferably, a plurality of limiting blocks are installed on the outer side of the pipe body, and the plurality of limiting blocks are evenly distributed on opposite sides of the moving groove.
[0012] Preferably, at least two positioning plates are installed at the lower end of the moving handle, and the two positioning plates are inserted into the limiting blocks.
[0013] Compared with the prior art, the utility model provides a tee pipe with an anti-freezing and explosion-proof mechanism, and has the following beneficial effects:
[0014] 1. In the utility model, by moving the fixed connection block, the movement of the fixed connection block drives the arc-shaped sliding rod to move. While the arc-shaped sliding rod moves inside the I-shaped guide rail, the arc-shaped sliding rod slides inside the sliding support ring. And by arranging the I-shaped guide rail inside the sliding support ring, the I-shaped guide rail contracts as the arc-shaped sliding rod slides, so as to simultaneously contract the middle elastic pipe, reduce the space inside the wall of the middle elastic pipe, and reduce the internal flow space of the pipe body. At the same time, by moving the fixed connection block in the reverse direction, the arc-shaped sliding rod moves in the reverse direction, so that the middle elastic pipe expands under its own elastic support, and expands the internal flow space of the pipe body.
[0015] 2. In the utility model, by expanding the internal flow space of the pipe body, the situation of blockage inside the pipe body is alleviated, and the explosion caused by blockage is prevented. At the same time, by expanding the middle elastic pipe, the volume of internal flow can be increased, and the anti-freezing effect of the device can be improved.
[0016] Parts not involved in the device are the same as those in the prior art or can be realized by using the prior art. The utility model has a simple structure and is convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0025] Embodiment 1: A tee pipe with an anti-freezing and explosion-proof mechanism, as Figures 1 - 5As shown in the figure, it includes a tube body 1, a fixing ring 2 and an auxiliary ring 13 installed on the inner wall. Fixed connection cylinders 3 are installed on both adjacent sides of the fixing ring 2 and the auxiliary ring 13. A middle elastic tube 4 is arranged between the two fixing rings 2. Both opposite sides of the middle elastic tube 4 are fixedly connected to the two fixed connection cylinders 3 at the same time. An I-shaped guide rail 5 is installed on the outer side of the middle elastic tube 4. An arc-shaped sliding rod 7 is slidably installed inside the I-shaped guide rail 5. The arc-shaped sliding rod 7 extends to the outside of the I-shaped guide rail 5. And sliding support rings 6 are slidably connected to both opposite ends of the I-shaped guide rail 5 at the same time. The sliding support rings 6 are installed on the inner wall of the tube body 1. A fixed connection block 8 is installed on the outer side of the arc-shaped sliding rod 7. The fixed connection block 8 is used for the movement of the arc-shaped sliding rod 7. When the device is in use, first move the fixed connection block 8. The movement of the fixed connection block 8 drives the movement of the arc-shaped sliding rod 7. While the arc-shaped sliding rod 7 moves inside the I-shaped guide rail 5, the arc-shaped sliding rod 7 slides inside the sliding support ring 6. And by arranging the I-shaped guide rail 5 inside the sliding support ring 6, the I-shaped guide rail 5 contracts as the arc-shaped sliding rod 7 slides, so as to simultaneously contract the middle elastic tube 4, reduce the space inside the inner wall of the middle elastic tube 4, and reduce the flow space inside the tube body 1. At the same time, by moving the fixed connection block 8 in the reverse direction, the arc-shaped sliding rod 7 moves in the reverse direction accordingly, so that the middle elastic tube 4 expands under its own elastic support, expands the flow space inside the tube body 1, so that when the inside of the tube body 1 is blocked, the flow space inside it can be expanded, alleviating the blockage inside the tube body 1 and preventing it from exploding due to blockage. At the same time, by expanding the middle elastic tube 4, the volume of the internal flow can be increased, and the antifreeze effect of the device can be improved.
[0026] As Figures 1 - 5 shown, one fixing ring 2, one auxiliary ring 13 and one middle elastic tube 4 operate as a group. And a group of fixing ring 2, auxiliary ring 13 and middle elastic tube 4 are installed inside each connection port of the tube body 1. The fixing ring 2, auxiliary ring 13 and middle elastic tube 4 arranged inside each connection head further improve the diversity of the device adjustment under their respective or simultaneous actions.
[0027] As Figures 1 - 5 shown, at least two I-shaped guide rails 5 are installed on the outer side of the middle elastic tube 4. Fixed connection blocks 8 are installed on the outer sides of the two arc-shaped sliding rods 7. And telescopic plates 9 are slidably installed on the upper ends of the two fixed connection blocks 8. A moving handle 10 is installed on the upper ends of the two telescopic plates 9 at the same time. The moving handle 10 is used for the moving support of the fixed connection block 8. When moving the device, by pulling the moving handle 10, the telescopic plate 9 extends a certain distance inside the fixed connection block 8, and then rotate the moving handle 10, so that the two fixed connection blocks 8 and the arc-shaped sliding rod 7 move at the same time, which is convenient to move the middle elastic tube 4 from two directions at the same time and improve the stability when adjusting the middle elastic tube 4.
[0028] Embodiment 2: A tee with an anti-freezing and explosion-proof mechanism, as Figures 1 - 5 shown, a moving groove 11 is formed on the outer side of the pipe body 1, and the number of the moving grooves 11 is the same as that of the telescopic plates 9. The telescopic plates 9 are inserted into the moving grooves 11. The moving handle 10 is located on the outer side of the pipe body 1. A plurality of limiting blocks 12 are installed on the outer side of the pipe body 1, and the plurality of limiting blocks 12 are evenly distributed on the opposite sides of the moving groove 11. At least two positioning plates 14 are installed at the lower end of the moving handle 10, and the two positioning plates 14 are inserted into the limiting blocks 12. While pulling the moving handle 10, the positioning plate 14 is moved out between two adjacent limiting blocks 12, and the limitation on the positioning plate 14 and the moving handle 10 is released. Then the moving handle 10 is rotated to make the telescopic plate 9 slide inside the moving groove 11. After the movement is completed, the moving handle 10 is put down to make the positioning plate 14 inserted into and limited by the limiting block 12, which is convenient for the movement and limitation of the device.
[0029] Working principle: First, pull the moving handle 10 to move the positioning plate 14 out between two adjacent limiting blocks 12, and release the limitation on the positioning plate 14 and the moving handle 10. Then rotate the moving handle 10 to make the telescopic plate 9 slide inside the moving groove 11, so that the fixed connection block 8 moves simultaneously. The movement of the fixed connection block 8 drives the arc-shaped sliding rod 7 to move. While the arc-shaped sliding rod 7 moves inside the I-shaped guide rail 5, the arc-shaped sliding rod 7 slides inside the sliding support ring 6. And by arranging the I-shaped guide rail 5 inside the sliding support ring 6, the I-shaped guide rail 5 contracts as the arc-shaped sliding rod 7 slides, so as to simultaneously contract the middle elastic tube 4, reduce the space inside the pipe body 1, and at the same time, by moving the fixed connection block 8 in the reverse direction, the arc-shaped sliding rod 7 moves in the reverse direction, so that the middle elastic tube 4 expands under its own elastic support, and the internal flow space of the pipe body 1 is expanded. After the movement is completed, the moving handle 10 is put down to make the positioning plate 14 inserted into and limited by the limiting block 12.
[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
