Description

Technical Field

[0001] This utility model relates to the field of pipeline emergency repair equipment, and more specifically, it relates to a PVC split joint for pipeline emergency repair. Background Technology

[0002] Pipeline splitters are a common type of emergency pipeline repair equipment. When a pipeline ruptures or leaks, the splitter is installed at the location of the rupture or leak to seal the leak and reduce the loss of fluid flowing through the pipeline. Existing splitters generally consist of two halves. To use them, the two halves are fitted onto the leaking pipe and bolted together. After installation, the splitter covers the leaking section. However, because the sidewalls of the splitter are fixed, it's impossible to observe the internal condition of the leak or install other equipment such as pumps at the leak location. It also hinders operations such as redirecting the leaking fluid, thus inconveniencing pipeline transport. Furthermore, pipeline leaks are generally caused by external impacts or collisions. After installation, the PVC splitter is easily damaged by impacts because its installation location remains unchanged. Existing splitters lack protective structures, thus affecting their normal operation. Summary of the Invention

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a PVC split joint for pipeline emergency repair, which has the following beneficial effects:

[0017] This utility model, through the setting of a protective structure, connects the protective frame and the half-half joint by using a fixing block on the half-half joint and a fixing plate on the protective frame during installation, with bolts inserted into the fixing holes. After the protective frame is installed, the protective plate is installed on the extension plate by using a mounting post and a mounting hole. The protective plate is then fixed by a threaded connection between a limiting plate and a mounting post. Thus, the cooperation between the protective plate and the protective frame shields and protects the half-half joint, reducing the risk of damage from impacts or collisions.

[0018] This utility model, by setting an outlet pipe on the half-half joint, allows the baffle to be pulled out between the two protruding blocks on the protective frame when other equipment needs to be installed on the half-half joint. This removes the bolt connection between the mounting plate and the outlet pipe, making it easier to connect the equipment to the outlet pipe. Thus, when other equipment needs to be connected, the half-half joint can be connected to other equipment, facilitating the use of the half-half joint.

[0019] This utility model increases the fit between the two half-half sections and the pipeline by setting a sealing ring and a sealing plate between them, thereby increasing the sealing degree between the half-half sections and the pipeline. The connection holes on the half-half sections and the connection holes on the protective frame, along with the bolts and nuts, facilitate the tight connection of the two half-half sections and clamp the sealing plate, thus facilitating the use of the entire half-half section.
