Technical Field
[0001] The utility model relates to a pipe plugging device, more specifically, to a simple cable threading pipe plugging device, belonging to the field of cable plugging. Background Art
[0002] At present, fireproof mud is mostly used to seal the cable threading pipes in chemical plants. When the fireproof mud is heated, the sealing mud will soften and overflow. When it is cold, the fireproof mud will harden and fall off to form a cavity. This brings hidden dangers in fire prevention, moisture prevention, and small animal prevention to the equipment operation environment, and in serious cases, it endangers the safe operation of the equipment. In addition, the overflowed and fallen fireproof mud adheres to the surrounding equipment and facilities, affecting the appearance of the equipment and facilities and the cleanliness of the environment. For this reason, we propose a simple cable threading pipe sealing device to solve the above problems. Utility Model Content

[0006] Preferably, a 9501 flame retardant rubber strip is provided on the outermost outer covering layer, and the 9501 flame retardant rubber strip can be wound around the sealing sheath and the outer insulation sheath of the cable at the same time.
[0007] Preferably, the blocking package is designed with an exhaust check valve to ensure that the gas inside the blocking package can be exhausted after installation.
[0008] Preferably, a cable tie is provided outside the sealing sheath, and the cable tie is used to tightly fasten the sealing sheath to ensure that the fireproof putty inside seals the cable protection sleeve.
[0009] When the cable tie is tightened, the exhaust check valve exhausts air, and the vacuum cylinder is used to evacuate the interior of the sealing package to ensure the sealing of the fireproof cement.
[0010] Preferably, the blocking sheath is in a truncated cone shape, the bottom edge of the blocking sheath is wrapped around the cable sleeve, and the top edge of the blocking sheath is wrapped around the cable.
[0011] Beneficial effects: When the utility model is in use, through the sealing coating body, one end is wrapped on the cable protection sleeve and fastened with a cable tie; one end is wrapped on the cable and fastened with a cable tie; the middle part is bonded and sealed with 9501 flame retardant adhesive strip, and then fastened with a cable tie to ensure the sealing and shaping of the fireproof glue plugging. When the fireproof mud is heated, the sealing mud will not soften and overflow, and when it is cold, the fireproof mud will harden and fall off to form cavities. The sealing and shaping are better, and the sealing effect of the glue is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS
