Forged steel Y type valve J45Y
Product Name:
Forged steel Y type valve J45Y
Description:
锻钢Y型截止阀 J45Y :

锻钢Y型截止阀有三种阀盖设计形式。第一种是螺栓式阀盖,按这种设计形式设计的阀门,其阀体与阀盖用螺栓螺母连接,缠绕式垫片(316夹柔性石墨制造)密封。客户有特殊要求时也可采用金属环连接。第二种设计形式是焊接式阀盖,按这种形式设计的阀门,其阀体与阀盖用螺纹连接,全焊密封。客户有特殊要求时也可采用全焊二连接。第三种为压力自紧式阀盖,按这种形式设计的阀门,其阀体与阀盖用螺纹连接,内压自密封环密封。
  可设计成“Y"型阀的有截止阀和止回阀。

压力自紧式Y型阀设计结构和特征

  1. 压力自紧封Y型截止阀和止回阀阀门符合ANSI B16.34。检验与测试按API598,标记按MSS-SP-25。
  2. 采用以下结构
  3. 全径或缩径
  4. 升降式和球式止回阀
  5. 按需内置弹簧
  6. 可拆卸实心阀瓣
  7. 自定心压板压套式
  8. 整体式上密封座
  9. 明杆支架型(OS&Y)
  10. 螺栓连接、缠绕垫片密封式阀盖,螺纹连接、全焊密封式阀盖以及螺纹连接内压自紧式阀盖
  11. 承插端符合ASME B16.11
  12. 螺纹连接端(NPT)符合ANSI/ASME B1.20.1
  13. 阀瓣可变换为针型、节流型、球型、止回型
