Embodiment Construction
[0015] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0016] combine figure 1 As shown in Figure 4, the shape of the oil inlet joint 1 of the present invention is cylindrical and flattened 182, one end is provided with an interface 110 with the hydraulic pipeline, and the other end is provided with several ear protrusions 181, which is convenient for ROV to carry and connect the joint ;The interior adopts the combination of piston structure and cone valve structure, and the position of the piston and the mandrel is adjusted by the oil supply pressure and the force of the spring, thereby controlling the on-off of the oil circuit. The joint includes an outer spring 11 and an inner spring 15, an adjusting gasket 12, an outer limit sleeve 13 and an inner limit sleeve 14, a piston 16, a mandrel 17, a housing 18 and an end cap 19, an interface 110, and ear protrusions 181 and so on. figure 1 It is the structural diagram ...

The invention provides an oil inlet connector of a rapid connection device used for a deepwater hydraulic pipeline. The oil inlet connector of the rapid connection device used for the deepwater hydraulic pipeline comprises an outer spring, an inner spring, an outer limiting sleeve, an inner limiting sleeve, a piston, a central shaft, a shell body and an end cap. The end cap is connected with the shell body. The piston is placed inside the shell body and can move relative to the shell body. An empty cavity is arranged in the piston and a horn mouth section is arranged in the empty cavity. The central shaft is placed in the empty cavity in the piston and penetrates out of the end cap. A circular table section matched with the horn mouth section is arranged on the central shaft. The outer limiting sleeve and the inner limiting sleeve are fixed on the central shaft and are respectively placed at the two sides of the end cap. The outer spring is sleeved on the piston and the inner spring is sleeved on the central shaft. A connection port of a hydraulic pipeline is arranged on the end cap. A lug protrusion is arranged at the end portion of the shell body. After the oil inlet connector of the rapid connection device used for the deepwater hydraulic pipeline is connected with an oil outlet connector, the rapid connection device used for the deepwater hydraulic pipeline is formed. In a deepwater environment, by means of mechanical arms carried by a remote operated vehicle (ROV), the rapid connection of the hydraulic pipeline can be completed rapidly, accurately and reliably.
Description
technical field [0001] The invention relates to a device for quick connection of deep water hydraulic pipelines, which is mainly used for quick connection of hydraulic oil circuits of deep water operation equipment during underwater operation. Background technique [0002] With the rapid growth of my country's offshore oil and gas development for relatively deep sea and deep sea oil development, the independent research and development of deep water operation equipment is imminent, and the research on related technologies of deep water hydraulic power sources has received more and more attention. In the underwater working process of deep-water operation equipment, the hydraulic quick coupling technology is also particularly important, which is the prerequisite for ensuring the rapid, safe and smooth progress of the project. Realizing the quick connection of the hydraulic oil circuit requires that after the device is connected, when the oil supply pressure of the deep water o...
