Installation and separation device of an underwater ball valve actuator

Abstract

The invention provides a mounting and separating device for an underwater ball valve actuator. The mounting and separating device is used for achieving the mounting, separating and recycling work of the underwater ball valve actuator and an underwater ball valve. The mounting and separating device comprises an upper component connected with the underwater ball valve actuator, and a lower componentconnected with the underwater ball valve. The upper component comprises an underwater robot interface, a right side board, an upper board, an upper cover board, a reset spring, an upper connection rod, a clamp cross beam, a left clamp, a right clamp, a left side board, a left nut, a lower board, a fixing part, a right nut and a lead screw. The lower component comprises a lower component shell, alower connection rod, a positioning pin top cover and a positioning pin. Through the arrangement mode of the upper component and the lower component, mounting and separating of the underwater ball valve actuator can be finished without need of hoisting the whole underwater ball valve and the underwater ball valve actuator, the function that the underwater ball valve actuator controls the underwater ball valve is ensured, and the problem that a traditional underwater ball valve and an actuator thereof are integrated and the underwater ball valve actor is difficult to change is solved.

Description

technical field [0001] The invention relates to a lower ball valve and its actuator, in particular to an installation and separation device for an underwater ball valve actuator, which belongs to the field of offshore oil engineering. Background technique [0002] As the global economy continues to grow, people's demand for energy will continue to increase, and oil and natural gas are currently one of the main energy sources in the world. At present, the energy on traditional land can no longer meet the huge demand brought by human beings due to social development, so the pace of human beings has gradually moved from land to ocean. [0003] The subsea production system was developed in the 1960s. It uses subsea well completion technology combined with fixed platforms, floating production platforms and other facilities to form different forms of offshore oil and gas field development. The underwater production system can avoid the construction of expensive offshore oil produ...

AI Technical Summary

Problems solved by technology

At present, the underwater ball valve and its actuator are all designed in an integrated form, that is, when the actuator fails, the underwater ball valve and its actuator need to be hoisted out of the water, disassembled and replaced on the water, and then hoisted. Re-installation on the seabed, the whole process takes too long, the process is cumbersome, the operation is difficult, and the cost is high
