Description:

弹性座密封闸阀(软密封闸阀) RVXX、RRXX、Z45X

 
 

一、用途

本厂引进欧洲高科技橡胶及阀门制造技术所生产的弹性座封闸阀,克服了一般闸阀密封不良、弹性疲乏、橡胶老化及生锈等缺陷,弹性座封闸阀利用弹性阀门产生微量弹性变形的补偿作用达到良好的密封效果,该阀具有开关轻巧、密封可靠、弹性记忆佳及使用寿命长等显著优点。可广泛用于自来水、污水、建筑、石油、化工、食品、医药、轻纺、电力、船舶、冶金、能源系统等流体管线上作为调节和截流装置使用。

二、特点

1.整体包胶: 阀门采用整体包胶,其良好的覆着性能与精确的几何尺寸,保证密封可靠,寿命长。

2.重量轻:阀体采用球铁制成,重量轻,安装维修方便。

3.平底式阀座:底部采用与水管相同的平底式阀座设计,不产生杂物淤积,密封更可靠。

4.耐腐蚀:内腔采用无毒环氧树脂涂装,防止腐蚀及生锈,不但可供生饮,而且可用于污水系统。

5.三“O”型环密封圈:由于阀杆采用三“O”型密封圈密封没计,可减少关闭时的摩擦阻力,大幅减少漏水现象及可以不停水施工更换密封圈。
