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, 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, ball valve, turn the hand wheel, high temperature valve, the valve stem can rise or fall, to lead the valve towards or away valve seat to close and open, welded ball valve, close the valve and valve seat match, valve structure, by pressure to the valve stem is pressed against the seat, when the valve is in a fully closed state, the valve does not leak tight.江苏兰 valve General Equipment Co., Ltd. passed IS09001-2008 quality system certification, product certification through the national explosion-proof electrical products for Quality Supervision and Inspection Center, made explosion-proof certificate and coal safety certificate.
