Abstract

The invention, which belongs to the field of the hydraulic technology, discloses a sealing detecting tool for double oil pipes. The detecting tool comprises an outer detecting assembly and an inner detecting assembly. The inner detecting assembly includes an inner choke plug and an inner joint; the inner choke plug is in sealing connection with one end of a to-be-detected inner oil pipe; the innerjoint is in sealing connection with the other end of the to-be-detected inner oil pipe; a first joint is arranged at the inner joint and is used for communication with the to-be-detected inner oil pipe. The outer detecting assembly includes an outer choke plug and an outer joint; the outer choke plug sleeves the inner choke plug in a sealing manner and is used for sealing connection with one endof a to-be-detected outer oil pipe; the outer joint sleeving the outer joint is used for sealing connection with the other end of the to-be-detected outer oil pipe; and a second joint is arranged at the outer joint and is used for communication with annular space between the to-be-detected outer oil pipe and the to-be-detected inner oil pipe. Therefore, the sealing detecting tool is used for sealing detection of the double oil pipes.

Description

technical field [0001] The invention belongs to the technical field of hydraulic pressure, in particular to a sealing detection tool for double oil pipes. Background technique [0002] The double oil pipe assembly is an important part of the controllable pitch propeller, which is used to realize the pitch change of the controllable pitch propeller. The double oil pipe is a part of the double oil pipe assembly, which includes an outer oil pipe and an inner oil pipe, the outer oil pipe is set outside the inner oil pipe, and both the outer oil pipe and the inner oil pipe are used to transport hydraulic oil. [0003] In order to ensure the normal operation of the double oil pipe assembly, before the double oil pipe assembly is officially put into use, it is necessary to perform a sealing test on the double oil pipe. [0004] However, the existing sealing detection tooling can only detect a single oil pipe, but cannot detect the double oil pipes that are set together at the same...
