摘要
为了分析插装阀压力飞升速率的影响因素,采用某型二通插装阀,结合数学与仿真模型分析相应的影响因素,使用AMESim对二通插装阀系统进行了仿真,并进行了相应的实验研究。首先,对插装阀的主要结构进行了分析,对插装阀压力飞升的相关标准进行了阐述,对插装阀的受力进行了分析;然后,对插装阀压力飞升的相关因素分别进行了分析,采用AMESim仿真软件建立了插装阀模型,分别分析了先导阀换向时间、管道长度、阻尼孔直径与代替、压力等级、流量等级对压力飞升速率的影响;最后,根据上述仿真结果,选用某型二通插装阀分别进行了瞬态实验,对插装阀的飞升要求进行了验证。研究结果表明:先导阀的换向时间对飞升速率有一定影响,随着换向时间变长,压力飞升速率呈现降速加快的趋势;管道长度对飞升速率也有一定影响,随着管道长度增加,压力飞升速率出现下降的情况;阻尼孔直径对压力飞升速率有影响,随着阻尼孔直径的增大,压力飞升速率呈现增速放缓的上涨趋势;阻尼孔的替代对压力飞升速率有影响,可加快压力飞升速率;压力与流量等级对压力飞升速率有显著的影响。
Aiming at the influencing factors of the pressure soaring rate,a certain type of two-way cartridge valve was used,and the corresponding influencing factors were analyzed by combining mathematics and simulation models.AMESim was used to simulate the two-way cartridge valve system and conduct corresponding experiments.Firstly,through the main analysis of the structure of the cartridge valve and the relevant standards of the pressure rise of the cartridge valve,the force analysis of the cartridge valve was carried out,and then the factors related to the pressure rise were analyzed through the corresponding simulation software.Firstly,the structure of the cartridge valve was mainly analyzed,the relevant standards of the pressure rise of the cartridge valve were studied,and the force analysis of the cartridge valve was also carried out.Then,the relevant factors of pressure rise were studied,and the influence of pilot valve reversing time,pipeline length,orifice diameter and substitution,pressure grade and flow grade on the pressure rise rate were analyzed by corresponding simulation software.Finally,according to the above simulation results,a certain type of two-way cartridge valve was selected to conduct transient experiments respectively,and the soaring requirements of the cartridge valve were verified.The results show that the reversing time of the pilot valve has a certain influence on the soaring rate.As the reversing time becomes longer,the pressure rise rate presents a trend of slow-down acceleration;as the pipeline length increases,the pressure rise rate decreases.As the diameter of the hole increases,the pressure rise rate shows an upward trend of slowing growth.The replacement of the orifice affects the pressure rise rate and can speed up the pressure rise rate.The pressure and flow level have a significant impact on the pressure rise rate.
