Ivalvu yevivane le-eccentric yinye
Kute kucatululwe inkinga yekukhipha emkhatsini we-disc kanye nesihlalo sevalve yevalve yeluvivane leconcentric, kukhicitwa ivalve yeluvivane le-eccentric yinye. Sakateka futsi unciphise kukhishwa kakhulu kwemaphetselo langetulu nalaphansi epuleti levivane kanye nesihlalo sevalve. Kepha, ngenca yesakhiwo sinye se-eccentric, lesento sekuklwebha emkhatsini we-disc kanye nesihlalo se-valve asinyamalali ngesikhatsi sonkhe sekuvula nekuvala kwe-valve, futsi libanga lekusebenta lifana nalelo le-valve ye-concentric butterfly, ngako-ke ayisetjentiswa kakhulu.
Ivalvu yevivane lephindvwe kabili
Ngesisekelo sevalve yeluvivane le-eccentric eyodwa, kungu ivalvu yevivane lephindvwe kabili lesetjentiswa kakhulu nyalo. Sici sayo sesakhiwo kutsi sikhungo shaft sicu valve siphambuka kusuka sikhungo disc kanye sikhungo umzimba. Umphumela we-eccentricity kabili wenta kutsi le-disc iphuke esihlalweni se-valve ngekushesha ngemuva kwekutsi le-valve ivulwe, lokucedza kakhulu kukhishwa lokungadzingeki kakhulu kanye nekuklwebheka emkhatsini we-disc nesihlalo se-valve, kunciphisa kumelana kwekuvulwa, kunciphisa kugcoka, futsi kwenta ncono imphilo yeSihlalo. I scraping kuncishiswa kakhulu, futsi ngesikhatsi lesifanako, .ivalvu yevivane lephindvwe kabili ingaphindze isebentise situlo sevalve yensimbi, leyenta ncono kusetjentiswa kwevalve yebutterfly ensimini lesetulu yekushisa. Noma kunjalo, ngoba umtsetfo wayo wekuvala isakhiwo sekuvala sesikhundla, lokusho kutsi, indzawo yekuvala ye-disc kanye nesihlalo se-valve isemugceni wekutsintsana, futsi kugucuka kwe-elastic lokubangelwa yi-disc extrusion yesihlalo se-valve kukhicita umphumela wekuvala, ngako-ke inetidzingo letisetulu tesikhundla sekuvala (ikakhulukati pressure w valve se), cabanga kutsi emavalvu e-butterfly akamelani nemfutfo lomkhulu futsi anekuvuza lokukhulu.
Ivalvu yevivane lephindvwe katsatfu
Kumelana nekushisa lokusetulu, kumele kusetjentiswe sivalo lesicinile, kepha linani lekuvuza likhulu; kuya ku zero leakage, kumele kusetjentiswe sivalo lesitfobekile, kepha asimelani nekushisa lokusetulu. Kute kuncotjwe kuphikisana kwevalve yeluvivane lephindvwe kabili, levalve yeluvivane beyi-eccentric kwesitsatfu. Sici sayo sesakhiwo kutsi ngesikhatsi sicu sevalve lephindvwe kabili eccentric si-eccentric, i-axis ye-conical yendzawo yekuvala ye-disc ithambekele ku-axis yesilinda yemtimba, lokusho kutsi, ngemuva kwe-eccentricity yesitsatfu, sigaba sekuvala se-disc asishintji. Bese kuba yindingilizi sibili, kepha i-ellipse, futsi kwakheka kwendzawo yayo yekuvala nako akulingani, luhlangotsi lolunye luthambekele emgceni losemkhatsini wemtimba, bese lolunye luhlangotsi luhambisana nemugca losemkhatsini wemtimba. Sici sale eccentricity yesitsatfu kutsi isakhiwo sekuvala sishintjwe ngalokuyinhloko, akusekho sikhundla sekuvala, kepha sivalo se-torsion, lokusho kutsi, akunciki ekugucukeni kwe-elastic kwesihlalo se-valve, kepha kuncike ngalokuphelele ekucindzetelekeni kwe-leakatal yekutsintsana kwesihlalo se-valve kufeza inkinga ye-zerofoling ye-Therefo, . valve situlo sixazululwa ngesikhatsi sinye, futsi ngenca yekutsi umfutfo wemhlabatsi wekutsintsana ulingana nemfutfo losemkhatsini, umfutfo lophakeme kanye nekumelana nekushisa lokusezingeni leliphakeme nako kuxazululwa kalula.
