Embodiment Construction

[0022] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0023] as attached figure 1 As shown, a marine oil circuit protection device includes an oil pipe 3 and a protective casing 1 sleeved outside the oil pipe 3 . There is a certain gap between the inner wall of the protective casing 1 and the outer wall of the oil pipe 3. When there is a problem with the oil pipe 3, the oil in the oil pipe 3 flows into the gap and can be stored therein for a certain period of time without leakage in a short time.

[0024] as attached figure 2 As shown, the protective sleeve 1 includes a cylindrical first body 13 and a plurality of first protrusions 11 arranged on the inner wall of the first body 13, and the...

Abstract

The utility model discloses a ship oil way protection device, which comprises an oil pipe and a protection sleeve sleeved outside the oil pipe. The protection sleeve comprises a first body and a plurality of first protrusions arranged on the inner wall of the first body, the first protrusions are distributed around the axis of the first body on the section perpendicular to the axis of the first body, a first recessed portion is formed between two adjacent first protrusions and the first body, and a pressure sensor device is arranged on the first recessed portion. The processing method of the protection sleeve comprises hot penetrating, cold drawing and cold rolling. The core rod for processing the protection sleeve comprises a connection section, a transition section and a working section which are sequentially connected. The working section comprises a cylindrical second body and a plurality of second protrusions arranged on the outer wall of the second body, the second protrusions are arranged around the axis of the second body circumferentially on the section perpendicular to the axis of the second body. Adjacent second protrusions and the second body form a second recessed portion respectively, and a groove communicated with the second recessed portion is arranged on the transition section.

Description

technical field [0001] The invention relates to a processing method for a marine oil circuit protection device, a protective casing and a mandrel for processing. Background technique [0002] The casing pipes of the marine mechanical equipment in the prior art cannot guarantee the overall strength of the oil pipeline and the leakage of the oil pipeline, let alone give an advance warning to the leakage of the oil pipeline. Contents of the invention [0003] In view of the above problems, the main purpose of the present invention is to provide a marine oil circuit protection device and a processing method for the protective casing and a mandrel for processing. The marine oil circuit protective casing has high strength, long service life and simple processing method . [0004] In order to solve the above problems, the solution adopted by the present invention is a marine oil circuit protection device, which includes an oil pipe and a protective casing sleeved outside the oil...
