Air valve anti-freezing device
The invention provides an air valve anti-freezing device. The air valve anti-freezing device comprises a bypass connecting pipe and a hydraulic self-driven suction component. The hydraulic self-driven suction component is mounted on the main pipeline at the downstream of the air valve, the hydraulic self-driven suction component comprises a forward driving turbine assembly and a reverse driving turbine assembly which are coaxially arranged, the lower end of a volute of the forward driving turbine assembly is communicated with the main pipeline, and the lower end of a volute of the reverse driving turbine assembly is communicated with the main pipeline through a pipeline; one end of the bypass connecting pipe is communicated with the lower cavity of the air valve, and the other end is communicated with the upper end of the volute inner cavity of the reverse driving turbine assembly; liquid flowing in the main pipeline serves as a power source to drive the forward driving turbine assembly to rotate, the forward driving turbine assembly drives the reverse driving turbine assembly to rotate, a negative pressure cavity is formed, and liquid in an air valve cavity is sucked into the main pipeline through the bypass connecting pipe. The air valve is easy to implement, high in reliability, low in cost, good in protection effect and capable of thoroughly solving the icing problem of the air valve.
本发明创造提供了一种空气阀防冻装置，包括旁通接管和水力自驱动抽吸部件；水力自驱动抽吸部件安装于空气阀下游的主管道，水力自驱动抽吸部件包括同轴设置的正向驱动涡轮组件和反向驱动涡轮组件，正向驱动涡轮组件的涡壳下端与主管道连通，反向驱动涡轮组件中的涡壳的下端通过管道与主管道连通；旁通接管的一端连通空气阀的下腔体，另一端连通反向驱动涡轮组件的涡壳内腔的上端；主管道流动的液体作为动力源驱动正向驱动涡轮组件转动，正向驱动涡轮组件带动反向驱动涡轮组件转动，形成负压空腔，通过旁通接管抽吸空气阀腔体的液体进入主管道。本申请易实施，可靠性高，成本低，防护效果好，能彻底解决空气阀结冰问题。
