The invention provides an underwater oil-gas conveying pipe hydraulic cylinder outward pushing type connecting device which is used for connecting two pipe sections of an underwater pipe. The hydraulic cylinder outward pushing type connecting device adopts a metal seal technology formed by a trapezoidal sealing ring and a conical sealing ring for conducting underwater hydraulic outward pushing connection pipe operation in combination with outward pushing power provided by a spline groove type movement guider, a spline sliding rail type shaft pushing connector, a laminated outward pushing baseand a hydraulic outward pushing system; and rapid catching of the connecting device and the underwater pipe is achieved through a butt-joint catcher, the butt-joint catcher is driven by the movement guider to slide in the axial direction through a movement pair between the movement guiding cylinder and a shaft pushing sliding rail, a blocking device axially extrudes the conical sealing ring through a blocking plate and a blocking shaft sleeve to form metal seal, the shaft pushing connector achieves bridging between the two pipe sections of the underwater pipe and provides a spline sliding railfor axial outward pushing, and the outward pushing base is used as a supporting point during axial outward pushing and achieves radial supporting for the hydraulic outward pushing system.
Description
technical field [0001] The invention relates to a pipeline connection device in the field of underwater oil and gas transportation, in particular to a hydraulic cylinder push-out connection device for connecting two pipe sections of an underwater oil and gas transportation pipeline. Background technique [0002] In underwater oil and gas production equipment, underwater oil and gas transmission pipelines are very important transmission equipment. On the one hand, offshore oil and gas fields are constantly adjusting and transforming underwater oil and gas transmission pipelines to meet the export demand of underwater oil and gas production liquids. At the same time, the surrounding oil and gas fields rely on When developing existing underwater facilities, it is also necessary to expand the laying scale of underwater oil and gas transmission pipelines. The underwater pipeline connection technology and its connection equipment are widely used in engineering practices such as dee...
