进口凸耳式中线蝶阀描述--
ALSO凸耳式蝶阀通常安装在管路末端做末端阀,由于其稳定的连接性,也常用于热变化频繁的管路上起截断和调节作用
进口凸耳式中线蝶阀结构--
阀杆:采用高強度单杆设计,阀杆与阀板的连接釆用双偏精密咬合设计,无需螺丝和销钉,避免与管线内的流体接触,防止泄露及腐蚀,而且拆卸上只需把阀杆从阀板拔出,安装及维修非常方便
阀座:采用舌槽接合式阀座设计,能够完全把阀体与管内介质隔离,具有更低的扭拒,阀座密封面有凸起O型环,无需在安装时另加法兰垫片
阀杆保持圆环:保持圆环把阀杆固定在阀体内一个推垫圈和“C”型垫片,用专用小工具就可拆卸,可防止阀杆无意拔出
阀杆套:四氟轴套,抗腐蚀,阻尼小,抗压能力强
密封圈:自调式双“U”环形设计的密封圈保证双向零泄露,并防止异物进入阀杆腔内
阀板:铸件边缘经过球面加工和手工抛光,使用寿命长,操作扭矩低,气泡密封双向零泄露
进口凸耳式中线蝶阀特点--
低扭矩、用途广、无泄漏;
大流量、免维护;
斜坡阀座,实现中线蝶阀结构;
带沟槽橡胶靠背,回弹性强;
万能孔,适应各种法兰标准的安装;
