摘 要：連桿蝶閥在很多場(chǎng)合都得到了應(yīng)用。通過(guò)對(duì)連桿蝶閥的運(yùn)動(dòng)軌跡進(jìn)行分析，得到了連桿蝶閥各參數(shù)之間的關(guān)系式和閥板運(yùn)動(dòng)軌跡，從而更好的了解閥門(mén)的運(yùn)動(dòng)特性，對(duì)流道進(jìn)行分析；然后調(diào)整各參數(shù)，通過(guò)求得的關(guān)系式進(jìn)行試算，得到最理想的運(yùn)動(dòng)特性。優(yōu)化設(shè)計(jì)，以滿足各使用場(chǎng)合的要求。

關(guān)鍵詞：連桿蝶閥；四連桿機(jī)構(gòu)；運(yùn)動(dòng)軌跡；關(guān)系式

Abstract：Link butterfly valve has been applied in many occasions. Through the analysis of the motion trajectory of the link butterfly valve， the relationship between the parameters of the link butterfly valve and the motion trajectory of the valve plate are obtained， so as to better understand the motion characteristics of the valve， analyze the flow channel， and then adjust the parameters. Through the trial calculation of the obtained relationship， the most ideal motion characteristics are obtained， and the design is optimized to meet the requirements of various applications.

Key words：Link Butterfly Valve; Four Bar Linkage; Motion Trajectory; Relation
