Automatic scaling removing device for valve

An automatic scaling removing device for a valve comprises a gate valve body, an upper cleaning pipeline and a lower cleaning pipeline, the gate valve body comprises a valve body, a valve cover, a valve clack and a valve rod, the valve cover is in sealed connection with a top flange of the valve body, the valve clack is installed at the bottom of the valve rod and located in a sealed cavity of the valve body, and the valve rod is installed in the valve cover in a sealed mode. The valve rod is rotated to drive the valve clack to move up and down in the sealed cavity of the valve body; the device has the advantages that the descaling speed is high, and the labor intensity of workers is reduced. 一种阀门自动除结垢装置，它包括闸阀本体、上部清洁管道和下部清洁管道，闸阀本体包括阀体、阀盖、阀瓣和阀杆，阀盖与阀体顶部法兰密封连接，阀瓣安装在阀杆底部，阀瓣位于阀体的密封型腔内，阀杆密封安装在阀盖内，通过旋转阀杆带动阀瓣在阀体的密封型腔内上下移动；优点是：除垢速度快，减轻了工人的劳动强度。
