Performance: Reducethe high upstream pressure to the required downstream normal usage pressure
产品详情 Product details
隔膜式可调减压阀阀体采用了全通道流线型设计、流体阻力小、流量大。在传动方式上采用了水力自动操作,即利用管路中的水压自动控制主阀的动作,主要安装在高层建筑给水系统以及其它给水系统的管道上,将较高的上游压力降为符合要求的下游使用压力。The imported diaphragm adjustable pressurereducing valve body adopts the full channel streamline design, with small fluidresistance and large flow. In terms of transmission mode, hydraulic automaticoperation is adopted, which utilizes the water pressure in the pipeline toautomatically control the action of the main valve. It is mainly installed onthe pipelines of the high-rise building water supply system and other watersupply systems, reducing the higher upstream pressure to the downstream servicepressure that meets the requirements.
进口隔膜式可调减压阀工作原理 Working principle
主阀安装在给水系统的管道上,主阀滑盘(阀瓣)通过液压导管的压力传递,模仿导阀的动作。当下游压力低于设定压力时,导阀开启,隔膜上方的压力水被排放至下游,排放速度大于入口的补充速度,主阀滑盘上移使下游压力增大至设定值。当下游压力高于设定值时,导阀关闭,隔膜上方的压力水向下作用在隔膜上,主阀滑盘向下移动,使下游压力降低至设定值,从而保持下游压力恒定。
进口隔膜式可调减压阀结构特点 Structural characteristics
1、关闭严密可靠。采用衬胶阀瓣密封,利用液压控制原理,使阀瓣关闭力成正比,密封可靠性高 Close tightly and reliably. Adopting rubber linedvalve disc sealing, utilizing hydraulic control principle to make the valvedisc closing force proportional, with high sealing reliability
2、过流量大。采用半直线型流道宽阀体和等过流量面积设计,阀门阻力小 Excessive flow. Adopting a semi linear flow channelwith wide valve body and equal flow area design, the valve has low resistance
3、运行安全,关闭速度可调,阀门动作平稳,启闭不产生压力波动,无管振和噪音 Safe operation, adjustable closing speed, stable valveaction, no pressure fluctuations during opening and closing, no pipe vibrationor noise
4、使用维护方便。主阀体可安装在水池外面,调试检查方便,维护简单 Easy to use and maintain. The main valve body can beinstalled outside the water tank, making debugging and inspection convenientand maintenance simple
