WAFER BUTTERFLY VALVES (2)

美国斯毕尔公司
 

基本安装知识
General Installation Information

  美国斯毕尔公司对夹蝶阀适用于安装在系统中符合美国国家标准协会ANSI B16.5 Class 150标准螺栓孔模式的两个法兰之间。这种阀门手柄(或者齿轮执行机构)是可反转180o,既可以向左也可以向右操作。这种对夹蝶阀内置法兰垫圈,并且适用于用户自备六角螺栓、螺母和平面垫圈的安装场合。这种阀门必须配带垫圈,并使垫圈面均匀地放置在相配合的法兰密封面之间。下表所列是阀门螺栓规格和螺栓长度的最低要求,但前提是采用的是美国斯毕尔公司的两个法兰,阀门内置垫圈,采用标准的S.A.E.六角螺栓和标准的平板“W”系列平面垫圈。
  Spears® Wafer Butterfly Valves are designed for system connections between two flanges having ANSI B16.5 Class 150 bolt hole patterns. The valve handle (or gear operator) is reversible 180o for either left or right side operation. Wafer Butterfly Valves have built-in flange gaskets and are designed for installation with user supplied, hex bolts, nuts and flat washers. The valve must be positioned with gasket areas evenly located between mating flange sealing surfaces. Valve Bolt Specification bolt lengths in table below are minimums based on use of two (2) Spears® flanges, Valve with built-in gaskets, standard S.A.E. hex bolts and Standard Plate "W" Series flat washers.
  注意:美国斯毕尔公司对夹蝶阀适用于安装在法兰或带有法兰的设备之间,其内部最小流道面积不能小于管道壁厚Schedule 80的PVC材质管道(ASTM D 1785)的流道面积。如果采用的法兰连接装置的内部直径较小,则可能导致阀门阀瓣和阀座的阻塞和损坏。
  Caution: Spears® Wafer Butterfly Valves are designed for use with flanges or flanged equipment having minimum waterway inside diameter no less than that of Schedule 80 PVC pipe (ASTM D 1785). Use of smaller inside diameter flange connections may result in obstruction and damage to the valve disc and seat.
