Tool Catcher and Ball Check Valve

Hydraulic Control Tool Catcher

The hydraulic control tool catcher is a safety device, which is mounted on the lower portion of the seal head and on the upper portion of the lubricator string.The hydraulic control tool catcher is mainly used for automatically grasping rope socket when tools are connected underground and are lifted to the top end of the lubricator, thereby effectively preventing cables from falling off the cable head or instruments drop in wells when the cable is broken when the cable head is impacted on the top end of the BOP because of very fast pulling speed or over big pull force. When a cable rope socket is released, the hydraulic control and grease injection pressure control system is used for pressurizing (operation pressure is no larger than 21MPa) to lead hydraulic force to push the piston in the catcher, the piston drives a robotic gripper which is opened, and then, the rope socket can be automatically released. When the cable rope socket is released, the hydraulic control system is used for pressurizing (maximum hydraulic control pressure should be no larger than 21 MPa.) to lead hydraulic force to push the piston in the catcher, the piston drives the robotic gripper to go upwards, the robotic gripper is braced up by the core sleeve, and then the rope socket can be released. The upper portion of the tool catcher is also provided with a ball valve device, which is also served as the blocking ball valve on the lower portion of the seal head.
Ball Check Valve

Function:After the wire be pulled out,prevent wellhead pressure from leaking.
