用途 User 主要应用于空调系统中，保持供/回水管路间的压差恒定，以提高系统效率及保障安全。 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. 特点 Characteristic 安装调试简单，一旦调定好即可实现自动控制，省去了阀门传感器及复杂的传动执行机构，维修方便，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 导阀的两个控制管分别与高压源（供水管）和低压源（回水管）联接。当高低压差大于设定值时导阀打开，主阀随之打开，一部分高压水通过800X直接流回回水管。压差恢复后，ZF800X自动关闭。 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. 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
