Background
The flange connection is a common form of pipeline sealing, and the flange is tightly pressed through fastening and fixing bolts, so that the aim of sealing and connecting pipelines is fulfilled. In real life, most of various control valves and monitoring instrument devices in water pipelines and heating pipelines and industrial production processes are connected and installed by flanges. The instrument is periodically checked, disassembled and assembled, and the replacement of the valve with the old pipeline fault is common and reciprocating work. In the process of newly installing or replacing a flange connection valve, due to the reasons of pipeline dead weight (poor strength) and the like, a flange is inevitably subjected to center line offset after being detached, bolt holes are staggered, the butt joint installation difficulty is high, and due to the fact that no standard operation tool exists, a prying bar is often used for roughly prying a pipe fitting, so that the construction time consumption is long, the labor intensity of workers is high, equipment damage or personnel injury can be caused carelessly, and the normal production management work is influenced. In order to change the above situation, an installation operation tool is required on the site to realize safe and standardized operation.
In the current production management process, when a gate or other equipment facilities break down, the gate or other equipment facilities are disassembled for maintenance and are updated for installation, the connecting flange is dislocated due to gravity sinking of a pipe network flow or the connecting tension of other equipment in the front and at the back, the operation is required to be crossed by multiple persons and is not standardized, the installation task can not be completed safely on time, and the damage or the injury of the personnel of newly-installed equipment facilities can be caused in the carelessness.
