Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tees, and in particular relates to a tee compensator. Background Art
[0002] Tees are also called pipe tees, tee pipe fittings, or tee joints. They are primarily used to change the direction of fluid flow and are used where a main pipeline branches out. They can be categorized by pipe diameter. They are generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, asphalt, PVC, and other materials.
[0003] In electrolyte delivery pipelines, metal pipes have strong pressure bearing capacity and good corrosion resistance, but they are heavy and prone to rust. Glass pipes have high transparency and strong corrosion resistance, but their pressure resistance is relatively low. Ceramic pipes have good chemical stability and strong corrosion resistance, but they are expensive and fragile. Therefore, the best choice is plastic three-way pipes because they have excellent corrosion resistance, high temperature resistance and pressure resistance.
[0004] When laying pipes in some flow battery systems with complex pipelines, horizontal, vertical, and oblique straight pipes are used in conjunction with various joints. Tees are commonly used at the junction of three pipes. However, due to differences in the pipeline layout and equipment interfaces, the straight pipe and the tee connection may be misaligned. In addition, the length may be too short due to inaccurate installation positions or inaccurate measurements, requiring re-cutting, which is not conducive to efficient pipeline installation. In some cases, straight pipe compensators are also used, but both ends of this compensator need to be connected to the pipeline separately, which is cumbersome to operate and the cost of purchasing them separately is relatively high.
[0005] In order to solve the above problems, this application proposes a three-way compensator. Utility Model Content
[0006] In order to solve the above problems existing in the prior art, the utility model provides a three-way compensator, which has the characteristics of improving the convenience and flexibility of the three-way connection while ensuring the reliability of the connection.
[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a three-way compensator, comprising a three-way pipe, at least one of the three pipe openings of the three-way pipe is fixedly connected to a compensating pipe, at least one of the three pipe openings of the three-way pipe is fixedly connected to a straight pipe, the compensating pipe is fixed with a connecting ring at one end away from the three-way pipe and the straight pipe is fixed with an end away from the three-way pipe, the compensating pipe and the straight pipe are externally fitted with a flange for sliding, and the compensating pipe is a bendable and length-adjustable corrugated pipe structure.
[0008] As a preferred technical solution of the present invention, the shortest length of the compensation pipe is within the external installation range of the flange.
[0009] As a preferred technical solution of the present invention, the three-way compensator is entirely made of plastic components.
[0010] As a preferred technical solution of the present invention, the pipe openings at the connection between the compensation pipe and the tee pipe are concentric, and the pipe openings at the connection between the straight pipe and the tee pipe are concentric.
[0011] As a preferred technical solution of the present invention, the compensation pipe and the tee pipe are connected in one piece by hot melt, and the tee pipe and the straight pipe are connected in one piece by hot melt or integrally formed.
[0012] As a preferred technical solution of the present invention, the front end of the flange is provided with an annular groove that matches the connecting ring.
[0013] As a preferred technical solution of the present invention, the flange is rotatably fitted on the outside of the connecting ring.
[0014] Compared with the existing technology, the beneficial effect of the utility model is: by directly connecting the bellows to the interface of the tee joint, a slip-on flange is provided at the other end of the bellows, the bellows can adapt to the deviation in length and misalignment between the tee joint and the connected pipe, and can be quickly connected through the slip-on flange, effectively improving the connection efficiency when the tee joint and the pipe need compensation, and the flexibility is effectively improved compared to the traditional one-piece tee.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] Example
[0023] See also Figure 1-4 The utility model provides the following technical solutions: a three-way compensator, including a three-way pipe 1, at least one of the three pipe openings of the three-way pipe 1 is fixedly connected to a compensating pipe 2, at least one of the three pipe openings of the three-way pipe 1 is fixedly connected to a straight pipe 4, and a connecting ring 5 is fixed to the end of the compensating pipe 2 away from the three-way pipe 1 and the end of the straight pipe 4 away from the three-way pipe 1, and a flange 3 is slidably fitted on the outside of the compensating pipe 2 and the straight pipe 4, and the compensating pipe 2 is a bendable and length-adjustable corrugated pipe structure.
[0024] Specifically, the shortest length of the compensation tube 2 is within the external installation range of the flange 3. In this embodiment, the shortest length of the compensation tube 2 is controlled to ensure that the flange 3 can still be normally connected to the external flange after the compensation tube 2 is bent.
[0025] Specifically, the three-way compensator is made entirely of plastic components. In this embodiment, the plastic components are lighter, less expensive, and more corrosion-resistant than metal components.
[0026] Specifically, the pipe ends of the compensation pipe 2 and the tee pipe 1 are fixedly connected with the same center, and the pipe ends of the straight pipe 4 and the tee pipe 1 are connected with the same center. In this embodiment, the connection between the compensation pipe 2, the straight pipe 4 and the tee pipe 1 needs to ensure the docking accuracy to avoid leakage and dislocation that affect the normal fluid transportation, and also to avoid increasing resistance. The compensation pipe 2 is only concentric with the fixed end of the tee pipe 1, and the rest of the compensation pipe 2 is bendable and retractable.
[0027] Specifically, the compensation pipe 2 and the tee pipe 1 are connected by hot melt, and the tee pipe 1 and the straight pipe 4 are connected by hot melt or integrally formed. In this embodiment, hot melt or integrally formed methods are used. Both methods are not prone to leakage, ensuring long-term reliability.
[0028] Specifically, the front end of the flange 3 is provided with an annular groove 31 that matches the connecting ring 5. In this embodiment, the annular groove 31 can partially embed the straight pipe 4 to play a positioning role. The straight pipe 4 is not embedded in the part connecting the sealing gasket. When it is docked with the external pipeline and the bolts are tightened, reliable sealing can be guaranteed.
[0029] Specifically, the flange 3 is rotatably fitted on the outside of the connecting ring 5. In this embodiment, the rotation of the flange 3 can facilitate accurate fitting with the bolt holes on the external pipe when docking with the external pipe, and has better adaptability.
[0030] The working principle and usage process of the utility model are as follows: the flange 3 at the front end of the connecting ring 5 is connected to the pipeline first to support the entire three-way compensator. At this time, even if there is a deviation or length mismatch between the compensation pipe 2 and the pipelines connected at both ends, compensation can be directly performed by relying on the bending property of the compensation pipe 2, thereby ensuring the rapid docking of the flanges 3 at both ends of the compensation pipe 2 with the flanges on the pipeline. It should be noted that when the flange 3 is connected to other pipelines and the pump body, a sealing ring is required at the docking point to avoid leakage.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
