Measurement device for pressure drop of no paper bag filter rod

The utility model provides a measurement device for pressure drop of no paper bag filter rod contains the electromagnetism valves and the gas piping of inclusion enclave mechanism, large -traffic negative pressure feed arrangement, low discharge negative pressure pressure drop measuring device, the discharge device that blows, changeable control gas circuit. The inclusion enclave is in -house to have the filter rod chamber that holds no paper bag filter rod, and slightly be less than no paper bag strains shaft to cross -sectional area S2 to its cross -sectional area S1. The electromagnetism valves have respectively with the valve pocket of four kinds of access & exit UNICOMs and the controlling means of their break -makes of control. The utility model discloses realizing the automatic operation of feeding, measurement, row's material, need not artifical action, work efficiency is high. 本实用新型提供了种无纸包滤棒压降的测量装置，含有包裹体机构、大流量负压进料装置、小流量负压压降测量装置、吹气排料装置、可切换控制气路的电磁阀组和气体管路。包裹体机构内部具有容纳无纸包滤棒的滤棒腔，其横截面积S1略小于无纸包滤棒轴向横截面积S2。电磁阀
