用途 User 该阀安装在配水管路需控制流量的场合，保持预定流量不变，将过大流量限制在一个预定值内，并且将上游高压减为下游低压。即使主阀上游的压力发生变化，也不会影响阀下游的流量。 The valve is installed in the situation where the water pipe line needs to control the flow, so as to keep the predetermined flow rate unchanged, the excessive flow is limited to a predetermined value, and the upstream high voltage is reduced to the lower pressure. Even if pressure changes upstream of the main valve, it will not affect downstream flow. 特点 Characteristic 安装使用方便，控制部分无复杂的电传感机构，不易出故障，设定简单，设定后自动完成调节功能，无需人工操作或其它动力源。 It is easy to install and easy to use. The control part has no complicated electric sensing mechanism. It is not easy to break down, set simple, and automatically complete the adjustment function after setting. No manual operation or other power source is required. 原理 Principle 该阀门的导阀从孔板处取得压差信号，控制主阀的开关。当管路流量大于设定流量时，主阀开度变小，流量恢复到原设定值时，阀瓣稳定不动。 The valve's guide valve obtains the differential signal from the orifice and controls the switch of the main valve. When the pipeline flow rate is greater than the set flow,the main valve is smaller, and the valve disc is stable when the flow is restored to the original setting value. 执行标准 Executive standard 法兰尺寸 Flange dimensions：GB/T 17241.6 试验检验 Test test：GB/T 13927 安装图典型 Installation diagram
