用途 User 該閥安裝在配水管路需控制流量的場合，保持預定流量不變，將過大流量限制在一個預定值內，并且將上游高壓減為下游低壓。即使主閥上游的壓力發生變化，也不會影響閥下游的流量。 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. 特點 Characteristic 安裝使用方便，控制部分無復雜的電傳感機構，不易出故障，設定簡單，設定后自動完成調節功能，無需人工操作或其它動力源。 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 該閥門的導閥從孔板處取得壓差信號，控制主閥的開關。當管路流量大于設定流量時，主閥開度變小，流量恢復到原設定值時，閥瓣穩定不動。 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. 執行標準 Executive standard 法蘭尺寸 Flange dimensions：GB/T 17241.6 試驗檢驗 Test test：GB/T 13927 安裝圖典型 Installation diagram
