The document discloses a utility model patent for a bridge plug setting tool and its setting method. The tool is composed of three sequentially connected sections: a power connection section, a dynamic balance section, and a propulsion section.
The core innovation involves the dynamic balance section, which includes a pressure providing structure and a movable balancing piston forming outer and inner pressure chambers. The propulsion section contains a hydraulic cylinder piston and a piston pull rod. By controlling the oil circuit via a directional control valve, the tool can switch between applying setting tension or thrust. This design addresses technical problems in existing pyrotechnic tools (low safety/success rate) and standard hydraulic tools (excessive length). This manual is written in Chinese.
It solves the low safety and success rates of pyrotechnic tools, as well as the excessive length that makes standard hydraulic tools difficult to use in actual construction.
This tool is designed to solve the problems of low safety and success rates in existing pyrotechnic setting tools, as well as the excessive length of general hydraulic setting tools.
The tool opens or closes a directional valve to switch the oil path, then moves the oil cylinder piston to drive the piston pull rod and provide setting tension or thrust.
