超流阀 EXCESS FLOW CHECK VALVES是一种安全保护阀,主要采锥型用密封面,弹簧控制流量,利用介质的流速推力控制管道上流量。当安装管道上流量压力超过弹簧设定压力自动关闭,自动开启时进口介质通过阀蕊上的小孔导流,两端压力平衡后弹簧自动收缩阀门开启。使用于油品、液化气、液氨、气氨等非腐蚀性介质。在管道内介质流速...

EXCESS FLOW CHECK VALVE This disclosure describes an improved valve, which may be used as a check valve, in which the flow of fluid in the direction to close the valve, is designed to operate the closure mechanism at a preselected rate of fluid flow. There is a......
An excess flow valve includes: a valve that opens and closes a flow path; a solenoid that keeps the valve in an opened state; a pressure detector detecting the primary-side pressure of the valve; and a controller controlling current flow to the solenoid based on pressure detected by the pre...
摘要: PROBLEM TO BE SOLVED: To improve the durability of a valving element for check and a valving element for an excess flow prevention, to prevent unstable behavior from being generated, and to achieve simplification and space saving.
