Description

Technical Field

[0001] The utility model relates to the technical field of cable sealing, in particular to a portable pressure-blocking device for side-to-side cables. Background Art

[0002] In the technical field to which the utility model relates, currently, common cable penetration seals usually adopt a packing compression structure. This structure has the advantages of high sealing pressure and simple structure. In this structure, the cable sealing device utilizes a packing nut to compress the rubber packing so that the packing is filled between the stuffing box and the cable. However, a long period of compression will cause the rubber material to age and lose its elasticity, which will lead to leakage of the sealing packing. Leakage usually occurs between the packing nut and the cable. Generally, in order to solve the leakage problem, the rubber sealing packing needs to be replaced. However, replacing the cable sealing ring requires disassembling the cable, especially for power and instrument cables that penetrate high-pressure water containers or underwater equipment. Disassembling the cable requires stopping the operation of some equipment. In addition, the cable disassembly process may cause water to enter the equipment.

[0003] In the past, cable sealing leakage problems in such places were usually solved by injecting sealant between the packing nut and the cable. However, the leaked water will make the sealant ineffective and unable to seal. In addition, the existing sealant cannot effectively seal high-pressure water. Utility Model Content
