GJ41X-6 Cast Iron Pinch Valve
Product Name:
GJ41X-6 Cast Iron Pinch Valve
Description:
铸铁管夹阀 GJ41X-6
          
 
 
一、结构和工作原结构:
 ⑴结构:本阀门有由上下铝合金阀体,橡胶管套、大小阀杆闸板、上下导柱等零件组成。
 ⑵工作原理:当顺转手轮时,使大小阀杆同时带动上下茬板、压缩管套、进行关闭,反之即行开启。这样,闸板在导柱之间上下往复完成阀门开闭工作,另因橡胶管套或承力小,所以在开闭时,操作人员旋转轮时只要感到适量抵触,均达到开闭极点。切勿尽力多人补助,禁用其他工具开闭。
二、安装及维修
 ⑴本厂生产管夹阀门尺寸符合机械工业部标准,出厂前经过试压GJ41X-6L按规定10Kg/cm2,GJ41X-10L16Kg/cm2试压持续5分钟无泄露,安装时不必拆洗调整更动。
 ⑵本阀门在管道上任意安装,没有介质流向限制,久时使用,如有磨损或泄露只需将阀体拆下调换新管套,其阀体可长期使用经济的确实惠。
