The first pipe has a first hole along its axial direction, and the second pipe has a second hole along its axial direction. Sealing grooves are formed around the inner walls of the first and second pipes at their adjacent ends, within the first and second holes. This invention features a novel structure and effectively solves the problem of poor installation and gas leakage in existing small-diameter gas pipes during threaded connections due to the lack of industry standards for the use of necessary auxiliary sealing materials such as PTFE tape and sealant.

This utility model discloses a novel quick-change mechanism for PTFE tape, including a main cylinder, an insert cylinder, staggered ribs, a rubber sleeve, a rubber cone cover, a comb plate, an inner ring rib, and a U-shaped side handle. The insert cylinder is embedded inside the main cylinder. By setting up a quick-change mechanism for replacing and cleaning PTFE tape, the main cylinder of the quick-change mechanism, with the rubber cone cover, is fitted over the metal tube containing the PTFE tape. Then, silicone oil-soaked and hardened PTFE tape can be sprayed on. After the main cylinder is removed, the insert cylinder is inserted and then screwed onto the outside of the metal tube, so that the comb plate inside the insert cylinder combs and cleans the PTFE tape in the thread groove of the metal tube. This facilitates quick cleaning of the PTFE tape at the metal tube and ensures that the PTFE tape at the metal tube can be quickly cleaned and replaced. The oil-soaked PTFE tape effectively ensures that the PTFE tape at the metal tube can be cleaned quickly and with low damage, preventing damage to the threads when cleaning and replacing the PTFE tape at the metal tube.

This utility model discloses a multifunctional PTFE tape reel core, the structure of which includes: an auxiliary groove and a shell structure. The improved shell structure allows the PTFE tape to be wound in a ring by a winding rod, and then, together with a side disc, embedded in the contact wall inside the edge shell to achieve a dustproof effect on the side and edge. The contact wall shell, combined with a restraining ring and a blocking block, restrains the side disc, allowing the side disc and winding rod to rotate stably, pulling the PTFE tape straight out from the output head. After the PTFE tape is used, it is hooked into a dedicated hook position through the hook groove at the front end, facilitating storage and preventing it from being mixed with other tools in the storage box and becoming difficult to find. Furthermore, the limiting frame set at the edge of the cutting groove at the front end of the output head improves the stable pulling effect of the PTFE tape. The small blade mounted on the inner wall of the limiting frame cuts the PTFE tape after use, replacing the irregular situation caused by direct pulling and tearing.

This utility model discloses a winding device for raw material tape production, including a base plate. Four fixing bolts are symmetrically connected to the four corners of the front side of the base plate. A circular groove is carved into the front side of the base plate, and a conversion plate is connected inside the circular groove. A take-up roller is equidistantly connected to the front side of the conversion plate. Raw material tape cores are equidistantly sleeved on the outer wall of the take-up roller. A locking positioner is connected to the front end of each take-up roller. An L-shaped connecting plate is provided in the middle of the top side of the base plate, and a punching positioning frame is fixedly connected to the front side of the L-shaped connecting plate. This device allows for the rapid replacement of multiple sets of wound raw material tape cores, automating the roll-changing operation during the winding process. This significantly improves the winding efficiency during raw material tape production. It also allows for the rapid disassembly and assembly of the raw material tape cores on the take-up roller, automatically completing the cutting operation without requiring manual cutting of the raw material tape on the wound cores.

This invention discloses an ultra-permeable PTFE microporous raw material tape for cables and its preparation method, relating to the field of cable materials. The microporous raw material tape comprises polytetrafluoroethylene (PTFE), a propellant, and hydrophobic porous particles. The hydrophobic porous particles are prepared by hydrophobic modification of porous particles with silane. Each porous particle includes a core layer and a shell layer; the core layer is naphthalene, and the shell layer is silica, with a molar ratio of (2-8):1. This application incorporates hydrophobic porous particles into the PTFE raw material tape. The naphthalene in the core layer can volatilize at high temperatures to form hollow particles, which, combined with the micropores of the silica shell layer, improves the air permeability of the raw material tape. When applied to cables, this increases temperature diffusion efficiency. Simultaneously, the porous particles provide a rigid framework, reducing irreversible deformation and improving tear resistance. The micropores of the hydrophobic porous particles can block water molecules with high surface tension, and, combined with the hydrophobic groups on the surface, enhance the water-blocking effect of the raw material tape, meeting the requirements of cable applications.
