混凝土分配阀的型式为闸板阀的混凝土输送泵,其吸粗料能力比较强（级配碎石粒度可达 50 mm）,所以应用较广。但由于使用和保养情况的不同,闸板阀的寿命有很大的差异,有的泵虽已泵送了 20 000 m3 的混凝土,但还能正常使用,而有的泵只泵送 1000 m3 混凝土就得更换闸板,甚至要更换整个闸板阀。根据我们的经验,为了延长闸板阀的使用寿命,应当注意以下几点。 The type of concrete distribution valve for the gate valve of the concrete pump, the suction ability of raw materials is relatively strong (graded gravel up to 50 mm), it is widely used. However, due to the use and maintenance of different conditions, the life of the gate valve is very different, although some pumps have been pumping 20 000 m3 of concrete, but also normal use, and some pumps only pump 1000 m3 of concrete You have to replace the gate, or even to replace the entire gate valve. According to our experience, in order to extend the service life of the gate valve, should pay attention to the following points.
