Description

Technical Field

[0001] This utility model relates to the field of four-way pipe fittings technology, specifically to a four-way pipe fitting structure that is easy to adjust. Background Technology

[0002] In piping systems, four-way fittings are used as key connecting components in petroleum, chemical, water supply and drainage and other fields to realize the diversion or merging of fluids. Traditional four-way fittings usually adopt a fixed size design, and the length of their branch pipes and the diameter of their interfaces cannot be adjusted. However, during pipeline installation or modification, due to differences in site layout or equipment displacement, it is often necessary to adjust the axial distance between the four-way fitting and the connecting pipe.

[0003] Typically, workers will customize welded crosses and prefabricate pipe fittings according to measured dimensions. However, this method has a long construction cycle, cannot adapt to temporary adjustment needs, and cannot achieve rapid and continuous length adaptation, making it particularly inefficient during emergency repairs or temporary pipeline construction.

[0004] Therefore, it is necessary to invent a four-way pipe fitting structure that is easy to adjust in order to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an easily adjustable four-way pipe structure. By cooperating with the four-way pipe body and the telescopic adapter mechanism, its practicality is improved, so as to solve the problem that the existing technology cannot adapt to temporary adjustment needs, cannot achieve fast and continuous length adaptation, and is particularly inefficient during emergency repairs or temporary pipeline construction.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable four-way pipe structure, comprising a four-way pipe body, four sets of telescopic adaptation mechanisms arranged around the four-way pipe body, each telescopic adaptation mechanism including four sets of outer protective pipes disposed on the outer side wall of the four-way pipe body, a telescopic steel pipe fixedly connected to the inner side wall of the outer protective pipe, an inner reinforcing pipe slidably connected to the outer side wall of the telescopic steel pipe, the inner reinforcing pipe fixedly connected to the inner side wall of the four-way pipe body, a first sealing block fixedly connected to the outer side wall of the telescopic steel pipe, a central steel pipe disposed on the outer side wall of the first sealing block, the central steel pipe fixedly connected to the outer side wall of the four-way pipe body, the central steel pipe sliding inside the outer protective pipe, and achieving length adaptation through the telescopic adaptation mechanism.

[0007] Preferably, a second sealing block is provided above the first sealing block, and the first sealing block is made of polytetrafluoroethylene composite material.

The fourth sealing block is fixedly connected to the inner wall of the outer protective pipe, and a double seal is achieved through the third sealing block and the fourth sealing block.

[0009] Preferably, an isosceles trapezoidal platform is fixedly connected to the end of the telescopic steel pipe away from the main body of the four-way pipe, and a wear-resistant component is fixedly connected inside the isosceles trapezoidal platform to resist the impact of particles in the medium.

[0010] Preferably, the wear-resistant part is made of silicon carbide ceramic, and several sets of reinforcing blocks are fixedly connected to the outer wall of the wear-resistant part to improve the performance of the wear-resistant part through silicon carbide ceramic.

[0011] Preferably, the isosceles trapezoidal platform has several sets of reinforcing grooves inside, and the inside of the reinforcing grooves is filled with glue. The reinforcing grooves are engaged with the reinforcing blocks, thereby improving the stability of the wear-resistant parts.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] Through the cooperation of the four-way pipe body and the telescopic adapter mechanism, a three-level nested telescopic structure design is adopted, consisting of an outer protective pipe, a telescopic steel pipe and an inner reinforcing pipe, to ensure a smooth and stable telescopic process.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model provides, for example Figure 1-4 The diagram illustrates an adjustable four-way pipe structure, comprising a four-way pipe body 1. Four sets of telescopic adapter mechanisms 2 are arranged around the four-way pipe body 1. Each telescopic adapter mechanism 2 includes four sets of outer protective pipes 201 disposed on the outer side wall of the four-way pipe body 1. Telescopic steel pipes 202 are fixedly connected to the inner side wall of the outer protective pipes 201. Inner reinforcing pipes 203 are slidably connected to the outer side wall of the telescopic steel pipes 202. The inner reinforcing pipes 203 are fixedly connected to the inner side wall of the four-way pipe body 1. A first sealing block 204 is fixedly connected to the outer side wall of the telescopic steel pipes 202. A central steel pipe 206 is disposed on the outer side wall of the first sealing block 204. The central steel pipe 206 is fixedly connected to the outer side wall of the four-way pipe body 1. The tube 206 slides inside the outer protective tube 201, and the length is adapted by the telescopic adapter mechanism 2. A second sealing block 208 is provided above the first sealing block 204, and the first sealing block 204 is made of polytetrafluoroethylene composite material. The second sealing block 208 is fixedly connected to the inner wall of the middle steel tube 206. The first sealing block 204 and the second sealing block 208 achieve a preliminary seal. A third sealing block 207 is fixedly connected to the outer wall of the middle steel tube 206. A fourth sealing block 205 is provided below the third sealing block 207. The fourth sealing block 205 is fixedly connected to the inner wall of the outer protective tube 201. The third sealing block 207 and the fourth sealing block 205 achieve a double seal.

[0023] Refer to the instruction manual appendix Figure 1-4An isosceles trapezoidal platform 3 is fixedly connected to one end of the telescopic steel pipe 202 away from the main body 1 of the four-way pipe. A wear-resistant component 4 is fixedly connected inside the isosceles trapezoidal platform 3 to resist the impact of particles in the medium. The wear-resistant component 4 is made of silicon carbide ceramic. Several sets of reinforcing blocks 5 are fixedly connected to the outer wall of the wear-resistant component 4 to improve its performance. Several sets of reinforcing grooves 6 are opened inside the isosceles trapezoidal platform 3, and the inside of the reinforcing grooves 6 is filled with glue. The reinforcing grooves 6 and reinforcing blocks 5 are interlocked, thereby improving wear resistance. The stability of component 4 is ensured by the cooperation of the four-way pipe body 1 and the telescopic adapter mechanism 2, which adopts a three-level nested telescopic structure design, consisting of an outer protective pipe 201, a telescopic steel pipe 202 and an inner reinforcing pipe 203, to ensure a smooth and stable telescopic process. The first sealing block 204 and the middle steel pipe 206 form an initial sealing interface, and a double seal is achieved through the third sealing block 207 and the fourth sealing block 205. The reinforcing block 5 adopts a dovetail groove connection structure, which forms a mechanical interlock with the reinforcing groove 6. The isosceles trapezoidal platform 3 can make the medium flow velocity transition smoothly and reduce the generation of eddies.

[0024] The working principle of this practical application is as follows:

[0025] Refer to the instruction manual appendix Figure 1-4 When length adjustment is required, the operator holds the end of the telescopic steel pipe 202 and applies force. The inner reinforcing pipe 203 serves as a guide reference, ensuring that the telescopic steel pipe 202 moves in a straight line. The precision guide rail inside the outer protective pipe 201 restricts radial sway. The first sealing block 204 maintains contact with the middle steel pipe 206 throughout the sliding process. After adjustment, the medium pressure acting on the conical surface of the sealing block will generate a self-locking effect. The static friction between the first sealing block 204 and the middle steel pipe 206, and between the third sealing block 207 and the outer protective pipe 201, is sufficient to resist conventional pipeline vibration, thus achieving self-locking. When the medium is introduced into the pipeline... After the medium acts on the first sealing block 204, it expands radially to fill the manufacturing tolerance. As the pressure increases, the third sealing block 207 undergoes elastic deformation, increasing the sealing contact width. The fourth sealing block 205 improves the sealing performance based on the same principle. When the medium containing solid particles passes through, the ceramic surface of the wear-resistant part 4 causes the particles to bounce, reducing direct impact. The reinforcing block 5 adopts a dovetail groove connection structure, forming a mechanical interlock with the reinforcing groove 6. The expansion structure of the isosceles trapezoidal platform 3 reduces the local flow velocity, causing large particles to settle, thereby improving its wear resistance and corrosion resistance, and reducing eddy current generation.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
