THERMAL INJECTION GAS VENT VALVE

INTRODUCTION

Suitable for COSL 9 5/8 "Thermal injection packer; Installed on the upper end of the 350℃ thermal  injection packer, the lower end is connected to the packer through 1.66 "NU PIN connection thread,  and the upper end is connected to the wellhead control valve through 1/4" hydraulic control line,  which can realize the opening and closing of the gas vent valve. After the gas vent valve is lowered to the design depth, the pressure enters the piston chamber of  the gas vent valve through the hydraulic control line , and the positioning cap is pushed downward  to overcome the spring force to open until the piston rod upward limit.Keep hydraulic control line  pressure, can maintain the gas vent valve in full open state;Discharge hydraulic control line pressure,  gas vent valve under the action of spring force up to the initial installation position, valve body and  valve seat contact, gas vent valve back to closed state.
