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形止回阀结构,并根据ASTM F 1970标准进行制造,结构材料应该是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形环类型的阀座阀瓣。所有O形环材质应该是EPDM或Viton®。在水温23oC条件下,所有通径DN15 ~ DN50阀门的压力等级应该是150 psi,所有通径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-Check configuration manufactured to ASTM F 1970 and 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 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

  美国斯毕尔公司Y形止回阀是一种斜角形止回阀,它通过阀瓣塞自身的重量来自动阻止流体回流。与球体止回阀相比,Y形止回阀比较不会受到湍流的影响,但关闭性能会比较差。可提供PVC灰,PVC透明和CPVC材质的Y形止回阀,可提供的国际管道标准IPS通径范围是DN15至DN100,可提供的连接端口有承插、SR螺纹或法兰,此外还有带承插和SR螺纹端口的真活接类型。
  Spears® Y-Check Valves are an angle type check valve that automatically stops reverse flow by the dead weight of the disc plug. Y-checks are less affected by turbulent flow and typically have lower shutoff characteristics than ball checks. Valves are available in PVC Gray, PVC Clear, and CPVC materials in IPS Sizes 1/2" through 4" with Socket, SR Threaded or Flanged end connections, plus True Union styles with Socket and SR Threaded ends.
