Experimental Study of Flow Resistance of a Metal Rubber Pressure Regulation Valve
-
摘要: 介绍了一种基于弹性多孔状金属橡胶材料的新型调压阀,并对金属橡胶调压阀进行了流阻特性及稳流试验。试验研究表明:流量、丝径相同时,孔隙度越小,金属橡胶元件产生的流阻越大,能调节的压力范围(ΔP=P2-P1)也越大;流量与孔隙度相同时,丝径越小,金属橡胶元件产生的流阻越大,能调节的压力范围(ΔP=P2-P1)也越大。同时,金属橡胶调压元件具有抑制流体振荡的作用,使流体流动更加平稳。Abstract: A new type of metal rubber pressure regulation valve was introduced. The apparatus for testing the metal rubber pressure regulation valve was designed,and experiments on the flow resistance of the metal rubber pressure regulation valve were done. The experimental results show that: 1) the flow resistance of the metal rubber pressure regulation valve with same wire diameter and flux increases,whereas its porosity decreases but the pressure regulation range( ΔP = P2-P1) increases; 2) the flow resistance of the metal rubber pressure regulation valve with the same porosity and flux increases,whereas the wire diameter decreases but the pressure regulation range ΔP = P2-P1) increases. The metal rubber pressure regulation elements can restrain the vibration of fluid and keep it flowing stably.
