Jiangsu Lan gate valve produced as a closing action of the valve, which is mainly made up of body, closing member and valve cover three parts. Seat in the body, stem drive valve opening and closing parts (disc) do lifting movement, Trafigura electrical devices, valves and valve seat of the clutch, the valve opening and closing. The valve opening and closing mechanism (also known as the valve disc, valve), the valve stem and the drive device (handwheel) components. Stem trapezoidal screwing the valve cover, handwheel and valve fixed in the upper and lower ends of the stem, handwheel stem may rise or fall, to drive valve toward or away from the valve seat to close and open, close the valve and valve seat match, by the pressure to the valve stem is pressed against the valve seat, electric equipment, then the valve is in a fully closed state, the valve does not leak tight.江苏兰 valve General Equipment Co., the latest development of intelligent electric valve actuators, beautiful appearance, electric apparatus Which is good, easy to operate, stable performance, praised by users.
