Emergency device for automatic switching of water supply pipeline in emergency and control method
The invention belongs to the technical field of emergency valves, and particularly relates to an emergency device for automatic switching of water supply pipeline emergency situations and a control method.The emergency device comprises a water supply pipeline, an emergency valve and an emergency flow valve, the water supply pipeline comprises an input end and an output end, and the emergency valve is installed at the input end, provided with a trigger mechanism and connected to a water source; the emergency flow valve is installed at the output end, carries out low-flow conveying under the emergency condition of the water supply pipeline and is connected to the water unit, and the triggering mechanism is used for automatically triggering the emergency valve and switching the emergency valve from an open state to a closed state under the emergency condition of the water supply pipeline; when the water supply pipeline loses pressure, the input end is closed, the output end conveys water at low flow, part of water resources in the water supply pipeline continue to be supplied to the water consumption unit, direct waste is avoided, meanwhile, low-flow conveying continues, the possibility of the water hammer effect can be reduced, further damage to the broken position is avoided, and the service life of the water supply pipeline is prolonged. And waste of water resources is avoided.
本发明属于应急阀门技术领域，尤其涉及一种供水管道紧急情况自动切换的应急装置及控制方法，应急装置包括供水管道、应急阀以及应急流量阀，供水管道包括输入端和输出端，应急阀安装在输入端，且设有触发机构，并连接于水源，应急流量阀安装在输出端，且在供水管道紧急情况下进行低流量输送，并连接于水单元，其中，触发机构用于在供水管道紧急情况时，自动触发应急阀并使其由打开状态切换成关闭状态；通过在供水管道发生失压情况时，对输入端进行关闭，并将输出端以低流量输送，将部分供水管道内的水资源继续供应给用水单元，避免直接浪费，同时继续低流量输送，能够减少发生水锤效应的可能，避免破裂处进一步损坏，避免增大水资源的浪费。
