對開穿透式刀閘閥
off penetrable knife gate valve
本閥門是一種新型的快速流量調節(jié)的刀閘閥，具有兩端同時開啟、關閉的操作執(zhí)行器，成倍提高啟閉速度。可以通過行程指示表來直觀控制閥門開啟程度。此閥門一般使用于通風管道內控制風力調節(jié)，或者是煤渣流量排放調節(jié)。其結構是由閥體、閘板、閥座、閥桿、支架板、傘齒輪組成。具有兩塊閘板，兩個操作端。通過同時操作兩端執(zhí)行器，使得兩閘板做異向分離和合并動作的啟閉過程。其特點具有啟閉速度快，具有中心向兩邊調節(jié)流量的優(yōu)點，使得通徑介質始終是從中心向周邊均勻調節(jié)通過。此閥門可以根據客戶要求配置手動、氣動、電動的操作方式。
Off penetrable knife gate valve is a new type of fast-flow regulating valve with both ends opened and closed operation of actuators that can double increase headstock speed . It can control degree of the headstock of valve directly through travel indicator. This valve is usually used in the ventilation ducts to control the wind-conditioning or regulating emissions from coal cinder flows. It's composed of body , gate, seat, stem, yoke, bevel gear with two gates and two operator ends. Through operation of ends of the actuator make two gates do separate to different directions and combine action .Hoist speed and the advantage of flow from center to two sides to make path media uniform regulation through center to around. This kind of valve can be manufactured manual , pneumatic and electric according to client's requirements.
