Abstract

The invention provides a sealing detection device of a cable gland, and the device comprises a manual pressurization pump, a water injection pipe, a first cup-shaped pipe joint nut, a second cup-shaped pipe joint nut as well as a first rear baffle ring, a combined sealing ring and a second rear baffle ring which are located between the first cup-shaped pipe joint nut and the second cup-shaped pipe joint nut, wherein the left end of the first cup-shaped pipe joint nut is connected to the first rear baffle ring and compresses the combined sealing ring; the left end of the combined sealing ring is connected to the second rear baffle ring; the first cup-shaped pipe joint nut, the first rear baffle ring, the combined sealing ring, the second rear baffle ring and the second cup-shaped pipe joint nut wrap a cable inside; a front clamping buckle and a rear clamping buckle which are connected through buckling and threaded connection sleeve the outer layer; a sealed water injection cabin is formed between a sleeve and the cable, and the sleeve is formed by the front clamping buckle and the rear clamping buckle; and the manual pressurization pump communicates with the water inject cabin by the water injection pipe. The device provided by the invention can simulate cable gland states under different depth conditions, can detect sealing performance of a sealing material of the cable gland and has the advantages of high control precision, small and compact appearance and convenient operation.

Description

technical field [0001] The invention relates to the technical field of marine cable stuffing boxes, in particular to a cable stuffing box leak detection device. Background technique [0002] A large number of watertight cable stuffing boxes exist in ships, such as cable stuffing boxes for submersibles to wear pressure hulls, or cable stuffing boxes for surface ships to wear various pressure bulkheads. According to the requirements of the ship cable sealing process, the test of the sealing of the cable stuffing box on the pressure-resistant shell lasts for 5 minutes with the corresponding required water pressure to observe whether there is any water leakage, and it is required that when the sealing packing is changed on the ship, the simulation test should be carried out again. [0003] However, at present, due to the lack of corresponding testing tools, the sealing test of the cable stuffing box is seldom carried out according to the above requirements in practice, resulting...
