Ukutywinwa kukuthintela ukuvuza, kwaye umgaqo wokutywinwa kwevalvu ukwaphononongwa ekuthinteleni ukuvuza.Kukho izinto ezininzi ezichaphazela ukusebenza kokutywinwa kweiivalve butterfly, ikakhulu iquka oku kulandelayo:
1. Isakhiwo sokutywina
Ngaphantsi kokutshintsha kweqondo lokushisa okanye ukutywinwa kwamandla, isakhiwo sesibini sokutywina siya kutshintsha.Ngaphezu koko, olu tshintsho luya kuchaphazela kwaye lutshintshe amandla phakathi kweebini zokutywinwa, ngaloo ndlela kuncitshiswe ukusebenza kokutywinwa kwevalve.Ngoko ke, xa ukhetha isitywina, qiniseka ukuba ukhethe isitywina nge-deformation elastic.Ngexesha elifanayo, kwakhona qwa lasela ubuninzi bendawo yokutywina.Isizathu kukuba umphezulu woqhagamshelwano wesibini sokutywinwa awukwazi ukuhambelana ngokupheleleyo.Xa ububanzi bomnxeba wokudityaniswa kwendawo yokutywina kwanda, amandla afunekayo ukutywinwa ayanda.
2. Uxinzelelo oluthile lokutywinwa kwendawo
Uxinzelelo oluthile lomphezulu wokutywina luchaphazela ukusebenza kokutywinwa kweivalve yebhabhathanekunye nobomi benkonzo yevalve.Ngoko ke, uxinzelelo oluthile lwendawo yokutywina nayo yinto ebaluleke kakhulu.Phantsi kweemeko ezifanayo, uxinzelelo oluphezulu kakhulu luya kubangela umonakalo wevalvu, kodwa uxinzelelo oluncinci kakhulu luya kubangela ukuvuza kwevalvu.Ngoko ke, kufuneka siqwalasele ngokupheleleyo ukufaneleka koxinzelelo oluthile xa siqulunqa.
3. Iipropati ezibonakalayo ze-medium
Iipropati ezibonakalayo ze-medium nazo zichaphazela ukusebenza kokutywinwa kweivalve yebhabhathane.Ezi mpawu zomzimba ziquka ubushushu, i-viscosity, kunye ne-hydrophilicity yomphezulu, phakathi kwabanye.Ukutshintsha kweqondo lokushisa akuchaphazeli nje ukuthoba kwesibini sokutywina kunye nokutshintsha kobukhulu bamacandelo, kodwa kwakhona kunobudlelwane obungenakulinganiswa kunye ne-viscosity yegesi.I-viscosity yegesi iyanda okanye iyancipha ngokunyuka okanye ukunciphisa ukushisa.Ke ngoko, ukuze kuncitshiswe ifuthe lobushushu ekusebenzeni kokutywinwa kwevalve, xa kuyilwa iperi yokutywina, kufuneka siyiyile njengevalve enembuyekezo yobushushu njengesihlalo sevalve elastiki.I-Viscosity inxulumene nokungena kwamanzi.Xa phantsi kweemeko ezifanayo, i-viscosity enkulu, iyancipha amandla okungena kwamanzi.I-hydrophilicity yomhlaba ithetha ukuba xa kukho ifilimu kwindawo yesinyithi, ifilimu kufuneka isuswe.Ngenxa yale filimu incinci kakhulu yeoli, iya kutshabalalisa i-hydrophilicity yomphezulu, ibangele ukuvaleka kwemijelo yolwelo.
4. Umgangatho wesibini sokutywina
Umgangatho wesibini sokutywina ikakhulu kuthetha ukuba kufuneka sijonge ukhetho, ukudibanisa kunye nokuveliswa kwemathiriyeli.Ngokomzekelo, i-disc ye-valve ihambelana kakuhle ne-valve yesitulo sokutywinwa kwendawo, enokuphucula ukusebenza kokutywinwa.
Ukuvuza kweValve kuxhaphake kakhulu ebomini kunye nemveliso, enokubangela inkunkuma okanye izise ingozi ebomini, njengokuvuza kweevalve zamanzi ompompo, kunye neziphumo ezibi, ezinjengetyhefu, eziyingozi, ezinokutsha, eziqhumayo kunye nokuvuza kweendaba ezitshabalalisayo, njl. , sisisongelo esinzulu kukhuseleko lomntu, ukhuseleko lwepropathi kunye neengozi zongcoliseko lwendalo.Khetha amatywina afanelekileyo ngokweendawo ezahlukeneyo kunye neempawu zokusebenzisa.
