适用工况：在冶金行业的矿料输送环节，经常需要对管道中的矿料介质进行截断或放料操作。阀门关断后，阀门前后压差能够达到10.0mpa，物料在阀腔容成堆积，容易出现阀门密封不严或阀芯被物料冲刷破坏等故障。
applicable conditions: in the transportation of mineral materials in the metallurgical industry, it is often necessary to cut off or discharge the mineral media in the pipeline. after the valve is turned off, the pressure difference between the front and the back of the valve can reach 10.0 mpa, and the material is piled up in the valve cavity, which is prone to failure of the valve seal or the valve core being damaged by material flushing.
