Umahluko kwisakhiwo sevalvu yebhabhathane wahlula iintlobo ezine zeevalvu zebhabhathane, ezizezi:ivalvu yebhabhathane egxile kwindawo enye, ivalvu yebhabhathane enye engaqhelekanga,ivalvu yebhabhathane engaqhelekanga kabinikunye nevalvu yebhabhathane engaqhelekanga kathathu. Iyintoni ingcamango yale nto ingaqhelekanga? Ungasigqiba njani isigqibo sokuba uza kuyisebenzisa nini ivalvu yebhabhathane engqongqo, uza kuyisebenzisa nini ivalvu yebhabhathane engaqhelekanga enye, uza kuyisebenzisa nini ivalvu yebhabhathane engaqhelekanga kabini kunye nevalvu yebhabhathane engaqhelekanga kathathu? Abasebenzisi abaninzi abacaci kakuhle. Masifunde kunye.
Iivalvu zebhabhathane eziqinileyo, iivalvu zebhabhathane ezingaqhelekanga, eziphindwe kabiniiivalvu zebhabhathane ezingaqhelekangakunye neevalvu zebhabhathane ezi-eccentric ezintathu zibonisa inkqubo yokuvula nokuvala ngomzamo omncinci nokonakala kancinci kumphezulu wokuvala. Ngokumisela indawo yeshaft ejikelezayo yepleyiti yevalvu yebhabhathane, imeko yokuvala kunye nokuvula kwevalvu yebhabhathane inokutshintshwa. Phantsi kweemeko ezifanayo, i-torque yevalvu xa ivulwa iyanda ngokulandelelana. Xa ivalvu ivulwa, i-engile yokujikeleza efunekayo ukuze ipleyiti yevalvu yahlulwe kwitywina incinci ngokulandelelana.
Uphawu lolwakhiwo lwevalvu yebhabhathane engqongo kukuba iziko le-shaft yesiqu sevalvu, iziko leplate yebhabhathane kunye neziko lomzimba wevalvu zikwindawo enye. Ngokubanzi, ukuba iivalvu zebhabhathane ezingqongo zingasetyenziswa, kufuneka zisetyenziswe kangangoko kunokwenzeka. Ngenxa yokuba uhlobo lwe-concentric alufuni ukusebenza okuphezulu kokutywina ngokwesakhiwo okanye ukusebenza, yimveliso eqhelekileyo. Ukuze koyiswe ukukhuhla, ukukrwela, kunye nokuqinisekisa ukusebenza kokutywina, isihlalo sevalvu sevalvu yebhabhathane engqongongo senziwe ngerabha okanye i-PTFE kunye nezinye izinto ezithambileyo, eziyivalvu yebhabhathane ethambileyo. Oku kwenza ukusetyenziswa kweevalvu zebhabhathane ezingqongongongo kuxhomekeke kwimida yobushushu. Ukuze kusonjululwe ingxaki yokukhuhla kweplate yebhabhathane kunye nesihlalo sevalvu, kwaveliswa ivalvu yebhabhathane enye engaqhelekanga. Uphawu lwayo lolwakhiwo kukuba iziko le-shaft yesiqu sevalvu liyaphambuka embindini weplate yebhabhathane.
Ivalvu yebhabhathane engaqhelekanga kabini yeyona isetyenziswa kakhulu. Uphawu lwayo lolwakhiwo kukuba iziko le-shaft yesiqu sevalvu liyaphambuka embindini wepleyiti yebhabhathane nakwiziko lomzimba wevalvu. Iyaphambuka kwiindawo ezimbini eziphakathi, ngoko ke ibizwa ngokuba yivalvu yebhabhathane engaqhelekanga kabini. Uninzi lwazo luvalwe ngomgca. Xa umphezulu wokutywina uvaliwe, kukho ukungqubana phakathi kwepleyiti yediski kunye nesihlalo sevalvu, kwaye isiphumo sokutywina silungile kakhulu. Ineempawu zendawo encinci kunye noxinzelelo olunamandla. Emva kokuba ivalvu ivuliwe, ipleyiti yebhabhathane inokuqhekeka ngoko nangoko kwisihlalo sevalvu, nto leyo ephelisa kakhulu ukukhupha okungafunekiyo kunye nokukrwela phakathi kwepleyiti nesihlalo, inciphisa umgama wokuxhathisa ukuvula, ukuguguleka, kwaye iphucula ubomi benkonzo yesihlalo sevalvu.
Ivalvu yebhabhathane engaqhelekanga kathathu inesimo sesithathu esingaqhelekanga ngokusekelwe kwivalvu yebhabhathane engaqhelekanga kabini. Imilo yesibini sokutywina ayisiyokhoni ecacileyo, kodwa yikhoni engqindilili. Uninzi lwazo lunamandla omgama omfutshane kunye nesitywina somphezulu. I-stem shaft yevalvu yebhabhathane engaqhelekanga kathathu sisakhiwo seshaft esineenxalenye ezintathu. Amacandelo amabini eshaft yesiqu sevalvu yeshaft eneenxalenye ezintathu agxile, kwaye umgca ophakathi weshaft yecandelo eliphakathi uyaphambuka kwi-axis yeziphelo ezibini ngomgama ophakathi, kwaye iplate yebhabhathane ifakwe embindini. kwi-shaft. Ulwakhiwo olunjalo olungaqhelekanga lwenza iplate yebhabhathane ibe nesimo esingaqhelekanga kabini xa ivuliwe ngokupheleleyo, kunye nesimo esinye esingaqhelekanga xa iplate yebhabhathane ijika iye kwindawo evaliweyo. Ngenxa yesiphumo seshaft engaqhelekanga, xa isondele ekuvaleni, iplate yebhabhathane ihambisa umgama kumphezulu wekhoni yokutywina wesihlalo sevalvu, kwaye iplate yebhabhathane ihambelana nomphezulu wokutywina wesihlalo sevalvu ukuze kufezekiswe ukusebenza okuthembekileyo kokutywina. Ilungisa impikiswano yokuba isitywina esiqinileyo sinesiciko esibi, kwaye isitywina esithambileyo sinesiphumo esihle sokutywina kodwa asimelani nobushushu obuphezulu.
Ukuba kufuneka usebenzise ivalvu yebhabhathane ejijekileyo, ukuba kufuneka ukhethe ivalvu yebhabhathane ejijekileyo kabini okanye ivalvu yebhabhathane ejijekileyo kathathu, ikakhulu kuxhomekeke kwiimeko zokusebenza kunye nohlahlo lwabiwo-mali.
