| 118-3R (截止阀) / 1118-3R (角阀)
止回控制阀 / 独立开启和关闭速度控制器
阀门通径DN100及以下
(DN150及以上采用118-4R/6118-4R)
118-3R (Globe) / 1118-3R (Angle)
CHECK VALVE W/ SEPARATE OPENING
& CLOSING SPEED CONTROLS
Valves 4" & smaller (6" & Larger use 118-4R/6118-4R)
当进口压力超过出口压力时,ACV 118-3R允许流体流动。阀门无滴漏关闭后将产生压力逆转。开启和关闭速度是能够单独调节的。
118-R:没有速度控制器
118-1R:没有关闭速度控制器(通径DN32~DN150)
118-2R:开启速度控制器(通径DN32~DN150)
118-3R:独立的可调节开启和关闭速度控制器,DN100及以下
118-4R:独立的可调节开启和关闭速度控制器,DN150及以下
The ACV 118-3R permits flow when inlet pressure
exceeds outlet pressure. Should pressure reversal occur the valve closes
drip-tight. Opening and closing speeds are separately adjustable.
118-R - no speed control
118-1R - no closing speed (sizes 11/4-6)
118-2R - opening speed (sizes 11/4-6)
118-3R - separate adjustable opening and closing speed 4" & smaller
118-4R - Separate opening and closing speed (6" & Larger)
快速选型:阀门通径与管道口径相同。
QUICK SIZING: Valve size same
as line.
需要考虑的因素
Points to consider:
流体分流:
Distribution flow:
- 参阅技术参数 - 流量表中所需流量的压降
Refer to Engineering Data - Flow Capacity Chart
Pressure drop at required flow
- 参阅技术参数 - 压降表
Refer to Engineering Data - Pressure Drop Chart
流体止回
Check Flow
- 如果止回流速超过阀门表,则考虑在用户系统上选择加装安全阀(ACV 166)
If check flow velocity exceeds valve chart, consider
adding a relief valve (ACV 116) to your system

阀门性能
VALVE FUNCTION
- 当出口/下游压力超过进口/上游压力时,阀门按照控制的速度(可调节)进行关闭。
Valve closes at a controlled rate (adjustable)
when outlet/downstream
pressure exceeds inlet/upstream pressure
- 当进口/上游压力超过出口/下游压力时,阀门按照控制的速度(可调节)进行开启。
Valve opens at a controlled rate (adjustable)
when inlet/upstream
pressure exceeds outlet/downstream pressure
