Abstract

The invention relates to a tightness test device of a metal sheath, comprising a front sealing device and a rear sealing device, wherein the front sealing device comprises a press plate, a sealing pressing die, a cable core sealing soft rubber ring and a jacket, wherein the sealing pressing die is arranged at the rear end of the press plate; the cable core sealing soft rubber ring is arranged in the sealing pressing die and is wrapped on the periphery of a metal sheath cable core; the jacket is arranged outside the sealing pressing die and is mutually connected with the press plate; the rear sealing device has the same structure as the front sealing device; the front end in the center of the front sealing device is connected with a gas-pressure meter; and the rear end in the center of therear sealing device is connected with an inflating port. The invention has the advantages of simple operation, capability of being repeatedly used, low cost, high efficiency and the like.

Description

technical field [0001] The invention relates to the field of metal sheath cables, in particular to a metal sheath airtightness test device. Background technique [0002] In the metal sheath cable, the airtightness test of the metal sheath must be carried out. During the test, the two ends of the metal sheath must be sealed, and a barometer should be connected to the air to make the metal sheath reach a certain air pressure. After a period of time, check whether the air pressure has decreased to determine whether the metal sheath is leaking. In the past, when conducting tests, argon arc welding is usually used for welding and sealing to achieve the specified effect, but it is relatively troublesome in actual operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a metal sheath airtightness test device, which makes the operation easier. [0004] The technical solution adopted by the present invention to solve...
