Slurry valve is the main control valve for conveying mineral sand slurry in alumina working condition, which is required to achieve the high performance of "three resistances and one prevention, that is, wear resistance, pressure resistance, erosion resistance and scar prevention. At present, the product has fully met the domestic market demand, and has made a certain contribution to the expansion and increase of production of alumina industry, as well as better achievements in foreign exchange earning and saving. Slurry valve is mainly used in aluminum plant,
According to the actual needs of the slurry valve, the bottom structure is designed to be convex type, and the valve body is V-type, and the two working modes of lifting and lowering are provided. The inner cavity of the valve body is equipped with a scour and corrosion-resistant sealing ring, which can protect the valve body from medium scour and corrosion at the moment of opening the valve, and carry out special treatment on the sealing ring to make the surface hardness reach hrc56 ~ 62, with high wear-resistant and corrosion-resistant functions. According to the requirements, the valve disc seal is overlaid with cemented carbide on the cover, and the seal pair is sealed with wire to ensure the reliability of the seal and prevent the scaling. At the same time, the design of short stroke disc is adopted. It is widely used in chemical, petroleum, metallurgy, pharmaceutical, pesticide, dye, food processing and other industries. Various operation modes, such as manual, pneumatic (spring return, double acting, with and without hand wheel), electric, hydraulic, gear, etc.
Structural features of the product: 1. The valve shall be stored neatly in the general air drying and chopping warehouse. It is strictly prohibited to stack or store in the open air. Both ends of the valve diameter shall be blocked with blind plates. 2. Before installation, carefully check whether the marks and certificates on the valve meet the use requirements, clean the valve and remove the damage caused in the process of transportation and storage. 3. The valve can be installed in any working position, but it shall be convenient for maintenance and operation. 4. During installation, the standard torque wrench shall be used to tighten the studs of the connecting flange symmetrically and staggered, and avoid twisting or over tightening. 5. The valve rod thread and the part with thrust bearing must be lubricated regularly. 6. The maintenance of the electric device shall be carried out in accordance with the requirements of "valve electric device manual.
