Design of multi-function valve group for the hydraulic control system of scraper conveyor
REN Xiyi
Abstract：To achieve the extensible tail,auxiliary chain tightening,lubrication,and cooling functions,decentralized installation of hydraulic control valves with different functions are commonly applied for the hydraulic system of the scraper conveyors in fully mechanized coal mining faces adopts,which results in complex hydraulic piping,disorganized on-site layouts,frequent failures,and difficulties in troubleshooting.To address these issues,a multi-functional integrated hydraulic valve manifold is proposed,consisting of a main valve fluid distribution block,an embedded chain tightening motor valve block,an embedded telescopic tailgate valve block,an embedded lubrication system valve block,and an embedded cooling water system valve block.The hydraulic schematic diagram and reasonable structure of the valve manifold are designed,and experiment are conducted to obtain performance curves for the overflow and pressure-reducing valves,verifying the effectiveness of the multi-functional valve manifold.This valve manifold realizes centralized control,management,and monitoring of various hydraulic modules in the coal mine scraper conveyor,streamlines hydraulic piping,simplifies installation processes,enhances the convenience of equipment management and maintenance,and has significant potential for promotion and application.
