BRIDGING PREVENTING SYSTEM OF APPARATUS FOR SUPPLYING POWDER SAMPLE WITH HIGH PRESSURE

摘要

PURPOSE: A bridging preventing system of an apparatus for supplying a powder sample with high pressure is provided to integrate a pressurizing element with a bridging preventing system by mounting a pressurizing line from a pressurizing valve to a lower end part of a supplied powder sample in an upper hopper, so that pressurizing of the upper hopper and the flowing of the powder sample are performed simultaneously by pressurizing gas. CONSTITUTION: A bridging preventing system of an apparatus for supplying a powder sample with high pressure, includes a first limit switch(30) for sensing a closing of an upper hopper valve(11) to transmit a signal to a pressurizing valve(12), a plurality of pressurizing lines(40) branched from the pressurizing valve and extended into an upper hopper(10) for flowing the powder sample in the upper hopper when applying a pressure, a pressure transmitter(50) for detecting a pressure of the upper hopper to transmit the pressure to the pressurizing valve, and a second limit switch(60) for detecting a closing of a lower hopper(20) to transmit a signal to a vent valve(14).
