我厂使用较多的闸阀是普通平行板铸铁闸阀。实践证明,在矿浆管路中使用这种闸阀弊病较多。1984年起,我厂采用辽宁开原县上肥阀门厂生产的胶管阀,效果一直较好。现将胶管阀的使用情况简介如下。 (一) φ24米浓密机放矿闸阀改用6英寸胶管阀过去浓密机的放矿闸阀采用6英寸普通铸铁闸阀。在正常生产时,闸阀处于全开状态。由于浓密机地下室比较潮湿,丝杆容易锈死,启动不灵活。此外, I plant more gate valve is an ordinary parallel plate cast iron gate. Practice has proved that the sluice pipeline in the use of such valve more ills. Since 1984, our factory has adopted the rubber valve produced by Shangyuan Valve Factory in Kaiyuan County of Liaoning Province, the effect has been better. Now the use of hose valve profile is as follows. (A) φ24-meter thickener discharge valve to switch to 6-inch hose valve Past thickener discharge valve with 6-inch ordinary cast iron gate.
