Qwalasela Iindidi zeValve, ii-Aplikheshini kunye neekhrayitheriya zokuKhetha

Makhe sijonge kwiindidi ezahlukeneyo zeevalvu zokutshekisha kwaye sixoxe ngendlela ezisebenza ngayo, indlela ezisetyenziswa ngayo, kunye nendlela yokukhetha uhlobo oluchanekileyo. Iinkqubo ezenzelwe ukuvumela i-media media ukuba ihambe kwicala elinye kuphela ngokuqhelekileyo ineevalve zokujonga.Imizekelo yeendlela ezinjalo ziquka imibhobho yogutyulo, apho inkunkuma inokuhamba kuphela kwicala elinye.Iivalve zokujonga nazo zisetyenziswa apho ukubuya ngasemva kunokubangela umonakalo wesixhobo.Ngaphambi kokuba sifumane kwiintlobo ezahlukeneyo zevalve yokukhangela, izicelo, kunye neendlela zokukhetha, masiqale siqonde ukuba zisebenza njani iivalvu. Ivalve yokutshekisha okanye ivelufa yokukhangela sisixhobo esithintela ukuhamba kolwelo kwicala elinye kuphela.Iivalvu zokujonga zinezibuko ezimbini, indawo yokungena kunye neyokuphuma, kwaye ziyilelwe ukuthintela ukubuya umva kolwelo kwiinkqubo ezahlukeneyo zemizi-mveliso.Kukho iindidi ezahlukeneyo zokuphuma kwamanzi. iivalve zokujonga, kwaye ziyahluka kwindlela ebangela ukuba zivule kwaye zivale.Nangona kunjalo, zonke zixhomekeke kuxinzelelo oluhlukeneyo ukuvumela okanye ukukhawulela ukuhamba kwamanzi.Ngokungafaniyo nezinye iivalve kwiimarike, iivalve zokujonga azifuni i-levers, izibambo, i-actuator okanye i-valve. Ukungenelela komntu ukuze kusebenze ngokufanelekileyo.Zingabizi, zisebenzayo kwaye zilula ukuzisebenzisa.Oko kukuthi, i-valve yokukhangela iya kusebenza kuphela xa kukho ukuhlukana koxinzelelo phakathi kokungena kunye nokuphuma.Uxinzelelo oluncinci oluhlukileyo olumele lugqithise inkqubo ukwenzela ukuba I-valve yokuvula ibizwa ngokuba "uxinzelelo oluqhekezayo."Ngokuxhomekeke kuyilo kunye nobukhulu, ixabiso lalo xinzelelo oluqhekezayo luyahluka kunye ne-valve yokutshekisha.I-valve iya kuvala xa kukho uxinzelelo lwangemva okanye uxinzelelo oluqhekezayo luphezulu kunoxinzelelo lwe-inlet. Indlela yokuvala yevalve yokukhangela iyohluka ngokoyilo, okt ivelufa yokukhangela ibhola ityhala ibhola ngakwicala eliphumayo ukuze iyivale. Esi senzo sokuvala sinokuncediswa ngumxhuzulane okanye imithombo. Njengoko kukhankanyiwe ngaphambili, kukho iindidi ezininzi zee-valve zokutshekisha, nganye eyenzelwe ukusetyenziswa kwayo ekhethekileyo.Nangona kunjalo, uhlobo olubizwa ngokuba yi-spring-loaded in-line check valve isetyenziswe kwiindawo ezahlukeneyo zoshishino.I-Spring-type in-line check valves Zinemithombo, imizimba yevalve, iidiski kunye nezikhokelo.Xa uxinzelelo lokungena luphezulu ngokwaneleyo ukoyisa uxinzelelo lokuqhekeka kunye namandla entwasahlobo, ityhala i-valve flap, ivule umngxuma kwaye ivumele ulwelo ukuba luhambe ngevalve. iya kutyhala intwasahlobo kunye ne-disc ngokuchasene nomngxuma / i-orifice, ukutywina i-valve.Umgama omfutshane wokuhamba kunye ne-spring-acting spring-spring ivumela ukuphendula ngokukhawuleza ngexesha lokuvala.Olu hlobo lwevalve lunokufakwa ngokuthe tye okanye ngokuthe nkqo, ngokuhambelana nenkqubo, kwaye ke ngoko kufuneka zisuswe ngokupheleleyo ukuze zihlolwe okanye zilungiswe. Ezi zilandelayo zezinye iindidi zeevalvu zokutshekisha: Ezinye iintlobo zeevalvu zokutshekisha ziquka iivalvu zeglowubhu, iivalvu zokujonga ibhabhathane/iwafer, iivalve zeenyawo, kunye neevalvu zokujonga idada. Iivalve zokukhangela zisetyenziswa phantse kuwo onke amashishini apho ulwelo kufuneka luhambe lubheke kwicala elinye.Ezi zivalo zikwasetyenziswa kwizixhobo zasekhaya ezinje ngoomatshini bokuhlamba kunye noomatshini bokuhlamba izitya.Ngokuxhomekeke kuyilo kunye nendlela yokusebenza, iivalve zokukhangela zingasetyenziselwa nayiphi na kwezi zilandelayo. iimeko zokusetyenziswa: Ezinye izinto ezinokuthi ziqwalaselwe xa ukhetha ivalve yokukhangela ziquka: Ukuhambelana kwezinto zevalve yokukhangela kunye ne-fluid medium. Iivalve zokujonga zizixhobo ezithandwayo kwiindawo zoshishino ezingabizi kwaye zithembeke kuphela, kodwa zilula kakhulu ukuzisebenzisa.Xa uthenga i-valve yokukhangela, qiniseka ukuba uyaziqonda iimfuno zakho ezizodwa kwaye ukhangele indlela yokukhetha i-valve.Kwakhona, qiniseka ukuba uyakuqonda ukufakela iimfuno ukunqanda imiba yesalathiso sokuhamba okanye umonakalo kwisixokelelwano sakho ngenxa yokwakhiwa koxinzelelo.
