AI Technical Summary

Technical Problem

Existing emergency detachment devices are prone to interference and misoperation during commissioning, resulting in insufficient reliability and high maintenance difficulty in the later stages.

Method used

The valve closing and adjustment mechanism adopts a split type, including a main valve body, an upper ball valve, a lower ball valve, a longitudinal guide pipe, and an electrically controlled switching valve. Through the cooperation of the split valve closing module and the electrically controlled switching valve, precise control of the valve core is achieved, avoiding interference with the clamp. The detachable structure design facilitates installation and maintenance.

Benefits of technology

It improves the operational safety and reliability of the emergency disengagement device, reduces the difficulty of later maintenance, and has low modification costs and a simple and robust structure.

Abstract

The present application relates to the technical field of fluid handling equipment, and particularly relates to a split type valve closing debugging mechanism with an emergency release device ERC, which comprises a main valve body externally mounted with a clamp, the main valve body is provided with an upper ball valve, a lower ball valve, an upper material guide pipe fixed on the upper end opening of the upper ball valve through an upper flange bolt, and a lower material guide pipe fixed on the lower end opening of the lower ball valve through a lower flange bolt. The split type valve closing debugging mechanism with the emergency release device ERC can facilitate early installation and later maintenance by adopting a split type detachable structure design. The split type valve closing debugging mechanism is fixed and assembled with a longitudinal first flow guide pipe and a longitudinal second flow guide pipe through a side-mounted frame externally mounted on the side wall of the upper ball valve and the lower ball valve, and the split type valve closing module is controlled through external flow guide, and the control process will not affect the clamp operation, and the operation is more safe and stable.
