丹富斯暗杆沟槽闸阀的启闭件是闸板，闸板的运动方向与流体方向相垂直，闸阀只能作全开和全关，不能作调节和节流。闸板有两个密封面， zui常用的模式闸板阀的两个密封面形成楔形、楔形角随阀门参数而异 , 通常为 50, 介质温度不高时为 2°52'''' 。消防暗杆沟槽闸阀/丹富斯暗杆沟槽闸阀原理楔式闸阀的闸板可以做成一个整体，叫做刚性闸板；也可以做成能产生微量变形的闸板，以改善其工艺性，弥补密封面角度在加工过程中产生的偏差，这种闸板叫做弹性闸板，一般为法兰连接。消防暗杆沟槽闸阀/丹富斯暗杆沟槽闸阀原理

Dan fuss non-rising stem groove opening and closing a gate valve is ram, ram movement direction perpendicular to the direction of flow and the valve can only be fully open and close, not to adjust and throttling. Sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters, usually in the form of 50, when the medium temperature is not high for 2 ° 52 ' ' ' '. Wedge gate valve of the damper can be made into a whole, is called a rigid disc; Can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, the gate is called elastic disc, generally for flange connection.
