CHECK-ALL止回阀F1系列介绍
The Flange Insert (F1, F6, FP) valves are the ultimate check valve in flanged systems. They provide the simplest and most economical way to install check valves in a piping system. The valve body helps position itself while bolts are being installed and tightened. Two gaskets are required instead of the one normally used in a flanged joint. See page 53 or consult the factory for additional installation guidelines.
Flange Insert valves are designed to fit between two mating ANSI flanges. The “Spring Housing”, designated by the“A” dimension➊, is designed to be inserted into the upstream pipe, thereby helping to center it in the pipe. Therefore, there must be clearance between the spring housing and the pipe or flange. Generally speaking, the FIV Class 150 and 300 valves (F1) are designed for standard schedule pipe with Class 150 or 300 flanges, and the FIV Class 600 (F6) valves are designed for schedule 80 pipe with Class 150, 300 or 600 flanges.
The Flange Insert valve can also be used as a low pressure relief valve or vacuum breaker by using the desired spring settings.
NOTE: Many valves in this series can be supplied with B16.34 certification.
法兰插入式（F1、F6、FP）阀是法兰系统中的终极止回阀。它们提供了在管道系统中安装止回阀的最简单和最经济的方法。在安装和拧紧螺栓时，阀体有助于自行定位。需要两个垫圈，而不是法兰接头中通常使用的垫圈。有关其他安装指南，请参见第 53 页或咨询工厂。
法兰插入阀设计用于安装在两个匹配的 ANSI 法兰之间。 “弹簧座”，由“A”尺寸➊ 指定，设计用于插入上游管道，从而帮助其在管道中居中。因此，弹簧座与管道或法兰之间必须有间隙。一般来说，FIV 150 级和 300 级阀门 (F1) 设计用于带有 150 级或 300 级法兰的标准管路，FIV 600 级 (F6) 阀门用于带有 150、300 或 600 级法兰的 80 级管路。
通过使用所需的弹簧设置，法兰插入阀也可用作低压泄压阀或真空破坏器。
注意：该系列中的许多阀门都可以提供 B16.34 认证。
