Description

Simple pipe joint

The new type is a pipe connector, especially a simple pipe joint with a simple structure and can be quickly set at the end of a pipe body.

The pipeline system is based on the pipeline design and is configured with a plurality of branch pipe bodies and pipe joints are installed between the pipe bodies to connect them. The pipe joints of the prior art, such as the published pipe joint structure of Taiwan certificate number TWM551672, are improved. The structure has a body, and the hollow body has at least one nozzle. For example, if it has one nozzle, it can be assembled with one pipe, if it has two nozzles, it can be assembled with two pipes. If it is an embodiment with three nozzles, it can be assembled with one pipe. Assembled with the three-branch pipe body, the body is usually formed by metal casting or metal forging or other methods. Each orifice of the main body is provided with an O-ring and a fixed connection structure. The fixed connection structure includes a sealing ring, a restraint member, a control group and a positioning ring in sequence. The sealing ring can hold the O-ring located in the pipe body. The type ring is positioned, the restraint is located between the sealing ring and the control group, and the positioning ring is used to install the aforementioned multiple components in the pipe body. In addition, the inner wall of the body is formed with a hierarchical structure with different pipe diameters to provide O The installation of the ring, the sealing ring, the restraint, the restraint of the control group, and the positioning ring to achieve the positioning of the O-ring in a specific position in the body. The tube body can be inserted into the body by the restraint to be fastened and fixed by the O-ring. The profile ring seals the main body and the pipe body to complete the assembly between the pipe joint and the pipe body.

The prior art pipe joint is composed of multiple components and the inside of the body of the pipe joint is provided for the installation of various components. The internal components have different sizes and are formed into a class shape. Therefore, there are many components, and the external size (outer diameter) is relatively large. The complex structure leads to the disadvantage of higher overall production cost.

Also, when the pipe body is inserted into the body, the pipe body must penetrate through the control group's release parts, restraints, sealing rings and O-rings and other multi-layered components. In order to achieve the sealing effect with O-rings, the release part and the sealing ring The gap between the inner diameter and the outer diameter of the pipe body needs to be accurately controlled in a small range to avoid excessive loosening. This structure causes the relative displacement distance between the pipe body and the inside of the pipe joint to be theoretically reduced, but its components are many and complex, and it is not easy Control its stability and flexibility, and even cause the installed pipeline to be inflexible or excessively loose, and because the release member has a length, it is not easy to insert and assemble, which consumes assembling man-hours.

Furthermore, the thicker pipe wall of the main body makes the overall volume larger and takes up more space for installation, especially when the pipeline system is installed in a small space, causing inconvenience in construction.
