AI Technical Summary
When inspecting the bottom valve, it needs to be installed on the column, which leads to the problem of wasting manpower and time for disassembly and repair of unqualified bottom valves.
A bottom valve test jig was designed. By placing the bottom valve in the first placement cavity and connecting the high-pressure hose and oil pipe with a plug-in ring and a quick connector, the opening pressure and closing pressure of the bottom valve can be tested, avoiding direct installation and testing on the column.
It is possible to carry out inspection without installing a bottom valve on the column, saving manpower and time and improving inspection efficiency.
