Hydraulically actuated press connectors

Abstract

The invention provides a hydraulic driving type blocking pressing connector. The hydraulic driving type blocking pressing connector is formed by assembling an inner hexagonal fillister headed screw, an end cover, gland rings, O-shaped rings, an extruding body, a fixing screw, a base body, a housing, a pushing assisting body and a pipeline, wherein when the pipeline is correspondingly inserted into the end cover, the pushing assisting body, the extruding body and the base body and the end part of the pipeline is in contact with a thrust surface of the base body, all screws are screwed; when hydraulic oil is poured into a hydraulic oil pouring hole in the surface of the housing, the oil enters a hydraulic cylinder and can generate a left axial force and a right axial force, and the extruding body outwards moves to extrude a main bump and a secondary bump on the upper surface of the base body under the effect of the hydraulic oil so as to apply radial pressure on a main sealing ring and a secondary sealing ring on the base body, the main sealing ring and the secondary sealing ring can tightly press the surface of the pipeline, and a great contact force can be accordingly produced to enable plastic deformation of the pipeline surface to fill and block a mini pipe leaking channel, thus forming a reliable seal. The hydraulic driving type blocking pressing connector is simple to mount, and free of a special loading machine, and can synchronously realize sealing and fixing.

Description

technical field [0001] The invention relates to a hydraulically driven compression connector, which is suitable for quick repair and quick connection of ocean pipelines. Background technique [0002] At present, the connection methods of marine pipelines mainly include flange connection, welding and clamp connector. These three connection methods are time-consuming and costly, and fast connections cannot be realized in emergency situations. Moreover, due to the special environment of the ocean, some of the methods have a higher probability of connection failure. [0003] At present, domestic research on pipeline connection is still in its infancy, and the technology of pipeline connectors for quick connection through hydraulic pressure is still immature. However, foreign countries have relatively mature technologies and products in quick connection and repair of pipelines. Represented by the intelligent flange connector of Oceaneering Company in the United States, it is w...
