ELECTRIC FLUORINE-LINED CORRUGATED PIPE SINGLE-SEAT REGULATING VALVE

摘要

Disclosed is an electric fluorine-lined corrugated pipe single-seat regulating valve, comprising a valve body (1), a valve cover (2), a valve rod (3) and a valve core (4), wherein the valve body (1) is further provided with a mounting connection port (7), the mounting connection port (7) is provided with a middle flange (9), the middle part of a water channel between an inlet and an outlet (5, 6) of the valve body (1) is provided with a seal end face (10) matching the valve core (4), the valve core (4) is fixed at one end of the valve rod (3), the valve core (4) is arranged in the valve body (1), the mounting connection port (7) is connected to the valve cover (2) by means of the middle flange (9), and a filler sealing mechanism (11) is arranged between the valve cover (2) and the upper part of the valve rod (3); and a polytetrafluoroethylene corrugated pipe (13) is provided on the valve rod (3) in the valve body (1), two ends of the polytetrafluoroethylene corrugated pipe (13) respectively abut against an inner end face of the valve cover (2) and an end face of the valve core (4), the upper end of the valve body (1) is fixedly connected to an electric actuator (36) by means of a bracket (35), and an output end of the electric actuator (36) is fixedly connected to the top end of the valve rod (3). The electric fluorine-lined corrugated pipe single-seat regulating valve uses the polytetrafluoroethylene corrugated pipe as a first seal, effectively protecting a medium from leaking from the valve rod, and forming zero leakage. The opening or closing of a valve is controlled by means of the electric actuator, which achieves an accurate distance of travel, and is safe and reliable.
