Common measures to prevent blocking:
In addition to improving the traditional flow path, improving the linearity of the flow path and other anti-blocking measures, the following anti-blocking measures can be adopted for the adjustment and control of thick pulp, paper pulp, mud, ore pulp and other media.
1) The smoother the flow path, the more balanced the transition, the better. Aiming at the advantages of high concentration of thick slurry, poor fluidity, and easy settlement, a straight-through shell structure is adopted to minimize flow resistance and prevent clogging (that is, at the flange diameter of the shell, the outlet is one gear larger than the inlet). The measures are very effective for thick pulp and other occasions.
2) According to the calculation, the valve seat diameter can be reduced if necessary to increase the flow speed of the orifice to improve the "self-cleaning" function of the valve itself.
3) The flushing interface is added in front of the valve seat, and high-pressure air or water can be used to clean and flush the inner cavity of the shell, which greatly simplifies the maintenance and management work.
4) Use actuators with sufficient torque and strength.
