Y-PATTERN VALVES

美国斯毕尔公司
     

工程规格说明书范文
Sample Engineering Specification

  所有热塑性塑料阀门应该是Y形结构阀门,其结构材料采用PVC, ASTM D 1784分类12454,或CPVC, ASTM D 1784分类23447。所有阀门应该配置锯齿螺纹阀盖和标准O形环阀座阀瓣。所有O形环材质应该是EPDM或Viton®。所有阀门应该配置高强度抗冲击聚丙烯手柄。在水温23oC条件下,所有DN15 ~ DN50阀门压力等级为150 psi,而所有DN80 ~ DN100阀门压力等级应该是90 psi,并由美国斯毕尔制造公司制造。
  All thermoplastic valves shall be Y-Pattern configuration constructed from PVC, ASTM D 1784 Cell Classification 12454, or CPVC, ASTM D 1784 Cell Classification 23447. All valves shall have Buttress thread bonnet and standard O-ring type seating disc. All O-rings shall be EPDM or Viton®. All valves shall have high impact polypropylene handles. All 1/2" - 2" valves shall be pressure rated at 150 psi and all 3" - 4" valves shall be pressure rated at 90 psi for water at 73oF, as manufactured by Spears® Manufacturing Company.

 

特点 - PVC灰,PVC透明和CPVC
Features - PVC Gray, PVC Clear & CPVC

  这种Y形阀门是一种往下关闭类型截止阀,通过阀座阀瓣行程实现比例开启节流效果。正因如此,Y形阀门成为流量调节应用场合的理想选择。与标准截止阀相比,这种Y形结构能够减少压力损失。可提供国际管道标准IPS通径DN15 ~ DN100,承插、SR螺纹、法兰、承插活接头或SR螺纹活接头连接端口的Y形阀门。
  The Y-Pattern valve is a closing-down, globe type valve design that provides proportional opening to seating disc travel. As such, Y-Pattern valves are ideally suited for flow regulating applications. The Y-pattern configuration reduces pressure loss over that of standard globe valves. Available in IPS Sizes 1/2" - 4" with socket, SR threaded, flanged, socket union or SR threaded union end connectors.
