Embodiment Construction

[0010] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. Such as figure 1 As shown, a deep-water cable radial and longitudinal water resistance pressure test device consists of a sealing cover 1, a gasket 2, a U-shaped rubber pad 3, a screw joint 4, a pressure relief port 5, a pressure gauge 6, and a steel pipe with a screw joint 7. It is composed of bracket 8, water inlet 9, blind end sealing cover 10 and pressure pump 11.

[0011] During the radial watertight performance test, the cable passes through the middle of the sealing cover 1, the gasket 2, the U-shaped rubber pad 3, the screw joint 4, and the steel pipe 7 with the screw joint, and the U-shaped sealing ring 3 is installed on both sides to the screw joint 4 Inside, press the metal gasket 2 to the U-shaped sealing ring 3, tighten the sealing cover 1, and seal the gap between the cable sheath and the st...

Abstract

The invention relates to the technical field of wires and cables and in particular relates to a deep-sea cable radial and longitudinal water-blocking pressure test device. The deep-sea cable radial and longitudinal water-blocking pressure test device comprises a steel tube, wherein spiral joints are respectively arranged at the two ends of the steel tube; the spiral joints are matched with sealing covers or blind-end sealing covers; a gasket and an U-shaped rubber pad are arranged between the spiral joints and the sealing covers; a pressure meter and a pressure release opening are formed in the upper part of the steel tube; a water inlet is formed in the lower part of the steel tube; the water inlet is connected with a pressure pump through the water inlet tube. The deep-sea cable radial and longitudinal water-blocking pressure test device has the advantages that: firstly, the spiral joints, the U-shaped sealing ring, the gasket and the sealing covers are combined, so that the greater the water pressure, the tighter the sealing, and thus, a sealing problem between the cables and the equipment is solved; secondly, the structure is simple, the manufacturing is easy, the experimental operation is convenient, the cost is relatively low, and the popularization is convenient; and thirdly, by virtue of simple transformation, the radial and longitudinal water tightness performance test under the cable water pressure is adapted.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a deep-water cable radial and longitudinal water blocking pressure test device. Background technique [0002] At present, there is no special test equipment for the radial and longitudinal water resistance tests of cables under water pressure. As cables are increasingly used in deep water, the watertightness and water resistance tests of cables under water pressure It is particularly important. The purpose of the present invention is to provide a convenient inspection equipment for the longitudinal water resistance and radial water resistance of the cable, wherein the longitudinal water resistance can detect the overall longitudinal water resistance of the cable and the water resistance of the cable except for the insulation. Longitudinal water resistance performance of the cable. Contents of the invention [0003] The purpose of the present invention is to ...
