D-35.00-1 KGC铸造不锈钢刀闸阀(3)
KGC Cast Stainless Steel Knife Gate Valve (3)

美国DeZurik阀门
     

铸造的闸板引导与压紧装置
Cast Gate Guides and Jams

  在相当于时钟的3点、9点和12点的位置配置铸造闸板引导装置,为移动闸板提供支撑,由于是铸造结构,因此不会像焊接引导装置那样容易断裂。在阀体底部配置铸造的闸板压紧装置,能够安全地将闸板支撑压紧在阀座内,确保关闭的紧密有效。在关闭位置,所有阀门都具备承受完全的反向额定压力的能力。
  The cast gate guides at 3, 9, and 12 o'clock provide support for the moving gate and will not break off like welded guides. Cast gate jams at the bottom of the body hold the gate securely against the seat to assure positive shutoff. All valves are rated for full reverse pressure in the closed position.

法兰阀体
Lug Body

  凸面阀体配置钻孔的凸耳,符合美国国家标准化组织ANSI压力等级125/150尺寸标准。
  Raised-face body has drilled and tapped lugs in accordance with ANSI Class 125/150 dimensions.

高流量
High Flow Capacity

  完全的圆形流道设计实现高流量,并最大限度减少流体压降损失。美国DeZurik(德朱瑞克)KGC阀门的阀座内径与标准40管道的内径完全相同。
  Full, round port design allows high flow capacity and minimum pressure drop. DeZurik's KGC valve seat I.D. is equal to the I.D. of standard 40 pipe.


闸板边缘的半圆形倒角
Gate Edge Radius

  • 增强了密封性能
    Improves sealing
  • 延长了密封填料的寿命
    Improves packing life
  • 所需密封压力更小,因此减少了摩擦损伤
    Requires less compression and thus reduces friction
  • 避免容易导致腐蚀和侵蚀的尖状直角
    Eliminates sharp corners where corrosion and erosion first occur

 

圆形不锈钢闸板,具有超级的密封性能
Radiused Stainless Steel Gate
Provides Superior Seal

  304,316或317不锈钢闸板具有很好的耐腐蚀性能。闸板两侧经过精密的精磨加工工艺,能够防止密封填料和阀座的损坏。闸板的刀状斜面边缘能够将流体介质中的固体颗粒推开或切断。为了延长密封填料的使用寿命,提供超级密封性能,闸板边缘是圆形的。
  Gates are available in 304, 316 or 317 stainless steel for corrosion resistance. They have a precision ground finish on both sides to prevent packing and seat damage. The beveled knife-like edge pushes aside or cuts through solids in the flow stream. To increase packing life and provide a superior seal, the gate edges are rounded.

较低的边缘拉力
Low Rim-Pull Force

  坚固的铸造夹紧装置使得KGC粗壮结实的结构更加完美。手动操作阀杆增加的螺纹数意味着这种阀门所需的手轮边缘拉力更加小。
  A strong investment cast clip complements KGC's robust construction. More threads per inch on the manual stem mean this valve requires lower handwheel rim-pull force.
