Abstract
The embodiment of the invention provides a flexible joint of a guide pipe, which comprises a pipe sleeve, a sealing ring and a hoop structure, wherein the pipe sleeve is used for connecting two ends of the guide pipe; the sealing ring adopts an O-shaped sealing structure to ensure the sealing of the circulating medium; the hoop structure is a connecting piece between joints; and an electric lap joint structure is arranged outside the flexible joint and used for realizing an electric connection path.
Description
Technical Field
The invention relates to a flexible connector of a guide pipe, belonging to the technical field of aviation and land-mounted pipeline connection.
Background
At present, most of flexible joints used in China adopt straight-line knurling structures for sleeves, and therefore, certain inconvenience is brought to maintenance; and the flexible joint is used in a large number on airplanes or systems, but most joints are not provided with the function of preventing misoperation or locking leakage at present.
Disclosure of Invention
The invention provides a flexible conduit joint which can effectively improve the maintainability and the self-locking reliability, ensure quick opening and effectively prevent opening.
The invention provides a flexible joint of a guide pipe, which comprises a pipe sleeve, a sealing ring and a hoop structure, wherein the pipe sleeve is used for connecting two ends of the guide pipe; the sealing ring adopts an O-shaped sealing structure to ensure the sealing of the circulating medium; the hoop structure is a connecting piece between joints; and an electric lap joint structure is arranged outside the flexible joint and used for realizing an electric connection path.
Optionally, the clamp comprises two half-clamping rings, and the connection of the two half-clamping rings is completed by a hinge and adopts a pin fixing hinge structure.
Optionally, the clamp is provided with a double-safety lock structure for self-locking and preventing mistaken opening.
Optionally, a hand grip structure is arranged on the sleeve and used for rapidly detaching the sleeve.
Optionally, the double-safety lock structure includes a latch additional buckle, a safety belt, a fuse and a safety piece.
In conclusion, the flexible guide pipe joint provided by the invention optimizes the sleeve dismounting mode, applies a novel double-layer safety lock structure and greatly improves the maintainability, safety and reliability of the airplane.
Drawings
FIG. 1 is a schematic structural view of a flexible joint of a catheter according to the present invention;
FIG. 2 is a schematic structural view of another flexible joint for a conduit according to the present invention;
in fig. 1: 1. the pipe comprises a pipe sleeve, 2 parts of a sealing ring, 3 parts of a sleeve, 4 parts of a hoop, 4-1 parts of an inner layer lock and 4-2 parts of an outer layer lock.
Detailed Description
The invention discloses a flexible joint which comprises a pipe sleeve, a sealing ring and a hoop structure, wherein a double-insurance structure is adopted for self-locking in the hoop, and the sleeve is designed to be provided with a handle structure, so that the maintenance performance is improved. Because the disassembly mode of the sleeve is optimized, a brand-new double-safety lock structure is applied, the maintainability and the reliability are improved, and the flexible joint of the structure can be quickly opened and can be effectively prevented from being opened.
The double safety catheter flexible joint provided by the invention is explained in detail below. The flexible joint comprises: 1. the pipe comprises a pipe sleeve, 2 parts of a sealing ring, 3 parts of a sleeve, 4 parts of a hoop, 4-1 parts of an inner layer lock and 4-2 parts of an outer layer lock. The pipe sleeve (1) is connected with the guide pipe part in a welding or spinning mode, the pipe sleeve (1), the sealing ring (2) and the sleeve (3) form a sealing pair of a flexible joint to ensure the circulation and sealing of working media, and the hoop (4) is used as a structural part to fix and limit axial and radial displacement.
The sleeve (3) is provided with a structure with a gripper, and when the flexible joint is mounted and dismounted, the gripper can be dismounted manually or by using a general tool without a special tool.
The double-safety lock structure (the inner layer lock 4-1 and the outer layer lock 4-2) ensures that the flexible joint can be opened quickly and can be prevented from being opened by designing the double-safety lock structure. The realization mode is various: the fuse comprises a safety belt, a fuse, a safety buckle, a safety sheet, a spring lock and a spring sheet, wherein a representative structure schematic diagram is shown in figures 1 and 2. The invention discloses a flexible joint which comprises a pipe sleeve, a sealing ring and a hoop structure, wherein a double-insurance structure is adopted for self-locking in the hoop. Because the disassembly mode of the sleeve is optimized, a brand-new double-safety lock structure is applied, the maintainability and the reliability are improved, and the flexible joint of the structure can be quickly opened and can be effectively prevented from being opened.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
