摘要：該設(shè)計(jì)是為了改善傳統(tǒng)球閥的缺點(diǎn)而做的，傳統(tǒng)球閥的缺點(diǎn)是摩擦大、使用壽命短、密封性能不好。此設(shè)計(jì)可以根據(jù)流體沖蝕磨損、腐蝕程度和工作壓力來調(diào)整密封比壓。軌道式無摩擦球閥是一種新型的球閥，它利用閥桿頭部的斜面凸輪與導(dǎo)軌套螺旋槽的配合來實(shí)現(xiàn)球閥的無摩擦開啟、關(guān)閉和金屬密封的新型閥門；所以設(shè)計(jì)中的關(guān)鍵問題是要避免產(chǎn)生摩擦，密封要緊，最終達(dá)到高效率、高質(zhì)量、耐用性等要求。本論文研究對(duì)軌道式無摩擦球閥的運(yùn)動(dòng)和動(dòng)力分析方法，完成了球閥啟閉運(yùn)動(dòng)軌跡、球體運(yùn)動(dòng)空間以及主要零部件的受力分析設(shè)計(jì)。該球閥具有啟閉無磨損，關(guān)閉時(shí)壓力可調(diào)節(jié)和啟閉省力的優(yōu)點(diǎn)；克服了普通球閥因密封比壓大而使密封面容易磨損的缺點(diǎn)，延長(zhǎng)了球閥的使用壽命。

Abstract: The design is to improve the shortcomings of traditional ball valve , and the shortcomings of traditional ball valve is friction, short life, sealing performance bad. According to this design`s fluid erosion, corrosion and pressure then the pressure was adjust sealed .Orbit Non-Friction Ball Valve is a new type of valve and realizes non-friction switching and metal pressurization of the valve by cam mechanism.This paper researches the design of Orbit Non-Fraction Ball Valve’s move and the analysis of dynamically. The paper puts forward the kinetic analysis method of Orbit Non-Fraction Ball Valve, analysising the track and motion space of the conglobulation for switching etc, and bring forward rule of its configuration design, designing its assembling body and main parts. This valve has a series of advantage, such as non-friction, the adjusting of pressure and laborsaving when it switches .Its pressurization is different from the usual whose pressurization is easy to destroy, which overcome the fault of the usual valves. So it has a longer life-span.
