用途 User 主要應用于空調(diào)系統(tǒng)中，保持供/回水管路間的壓差恒定，以提高系統(tǒng)效率及保障安全。 It is mainly used in the air conditioning system to keep the pressure differential between the supply and backwater pipes to improve the efficiency and safety of the system. 特點 Characteristic 安裝調(diào)試簡單，一旦調(diào)定好即可實現(xiàn)自動控制，省去了閥門傳感器及復雜的傳動執(zhí)行機構，維修方便，不易出故障。 It is easy to install and debug. Once it is set up, automatic control can be achieved. The valve sensor and the complex transmission actuator are eliminated. The maintenance is convenient and the failure is not easy. 原理 Principle 導閥的兩個控制管分別與高壓源（供水管）和低壓源（回水管）聯(lián)接。當高低壓差大于設定值時導閥打開，主閥隨之打開，一部分高壓水通過800X直接流回回水管。壓差恢復后，ZF800X自動關閉。 The two control pipes of the pilot valve are connected with the high voltage source (water supply) and the low voltage source (back water pipe). When the high and low pressure difference is greater than the set value, the guide valve opens, the main valve opens, and a portion of the high pressure water flows back through the 800X direct flow back to the pipe. ZF800X is automatically closed after the differential pressure is restored. 執(zhí)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
