Hlola Izinhlobo zeValve, Izicelo kanye Nemibandela Yokukhetha

Ake sibheke izinhlobo ezahlukene zama-valve okuhlola futhi sixoxe ngokuthi asebenza kanjani, asetshenziswa kanjani, nokuthi ungakhetha kanjani uhlobo olulungile. Amasistimu aklanyelwe ukuvumela imidiya ewuketshezi ukuthi igeleze iye ohlangothini olulodwa ngokuvamile inama-valve okuhlola. Izibonelo zalezo zinhlelo zihlanganisa amapayipi endle, lapho imfucumfucu ingagelezela ohlangothini olulodwa kuphela. Hlola amavalvu abuye asetshenziswe lapho ukugeleza emuva kungabangela ukulimala kwemishini.Ngaphambi kokuthi sithole ezinhlotsheni zama-valve okuhlola ahlukene, izinhlelo zokusebenza, kanye nezindlela zokukhetha, ake siqale siqonde ukuthi ama-valve okuhlola asebenza kanjani. I-valve yokuhlola noma i-valve yokuhlola iyithuluzi elikhawulela ukugeleza koketshezi ohlangothini olulodwa kuphela. Amavalvu okuhlola anezimbobo ezimbili, i-inlet kanye ne-outlet, futhi aklanyelwe ukuvimbela ukugeleza koketshezi emuva kumasistimu ahlukahlukene ezimboni. ama-valve okuhlola, futhi ayahluka endleleni ewabangela ukuba avuleke futhi avaleke.Nokho, wonke ancike ekucindezelweni okuhlukile ukuze avumele noma akhawulele ukugeleza koketshezi.Ngokungafani namanye ama-valve emakethe, ama-valve okuhlola awadingi ama-lever, izibambo, ama-actuator noma ukungenelela komuntu ukuze kusebenze ngendlela efanele.Zishibhile, ziyasebenza futhi kulula ukuzisebenzisa.Okungukuthi, i-valve yokuhlola izosebenza kuphela uma kunomehluko wengcindezi phakathi kokungena nokuphumayo.Ingcindezi encane yokuhlukanisa okufanele idlule isistimu ukuze i-valve yokuvula ibizwa ngokuthi "ingcindezi yokuqhekeka."Ngokuya ngomklamo nobukhulu, inani lalokhu kucindezela kokuqhekeka liyahlukahluka nge-valve yokuhlola.I-valve izovala uma kunomfutho wangemuva noma ukucindezela kokuqhekeka kuphezulu kunokucindezela kokungena. Indlela yokuvala yevalvu yokuhlola iyahlukahluka ngokwesakhiwo, okungukuthi ivalvu yokuhlola ibhola iphushela ibhola endaweni ephuma emlonyeni ukuze ilivale. Lesi senzo sokuvala singasizwa amandla adonsela phansi noma iziphethu. Njengoba kushiwo ngaphambili, kunezinhlobo eziningana zama-valve okuhlola, ngayinye yakhelwe ukusetshenziswa kwayo okuyingqayizivele.Nokho, uhlobo olubizwa ngokuthi i-spring-loaded in-line check valve lusetshenziswa ezimweni ezihlukahlukene zezimboni.Izinhlobo ze-Spring-in-line check valves babe nemithombo, imizimba yama-valve, ama-disc kanye neziqondiso.Lapho umfutho we-inlet uphakeme ngokwanele ukuze unqobe ukucindezela okuqhekeka kanye namandla asentwasahlobo, iphusha i-flap ye-valve, ivule imbobo futhi ivumele uketshezi ukuba lugeleze ku-valve.Uma ukucindezela emuva kwenzeka, kuyenzeka izophusha isiphethu kanye nediski ngokumelene nomgodi/i-orifice, ivale i-valve.Ibanga elifushane lokuhamba kanye nentwasahlobo esebenza ngokushesha ivumela impendulo esheshayo ngesikhathi sokuvala.Lolu hlobo lwevalvu lungafakwa ngokuvundlile noma mpo, ngokuhambisana nesistimu, ngakho-ke kufanele ikhishwe ngokuphelele ukuze ihlolwe noma ilungiswe.Lokhu okulandelayo ezinye izinhlobo zamavalvu okuhlola: Ezinye izinhlobo zamavalvu okuhlola zihlanganisa amavalvu okuhlola iglobhu, amavalvu okuhlola uvemvane/i-wafer, ama-foot valve, namavalvu okuhlola amadada. Ama-valve okuhlola asetshenziswa cishe kuzo zonke izimboni lapho uketshezi kufanele lugeleze luye ohlangothini olulodwa.Lawa mavalvu asetshenziswa nasezintweni zasendlini njengemishini yokuwasha neziwasha.Ngokuya ngomklamo nendlela yokusebenza, ama-valve okuhlola angasetshenziswa kunoma yikuphi kwalokhu okulandelayo. izimo zokusebenzisa: Ezinye izici okufanele zicatshangelwe lapho ukhetha i-valve yokuhlola zihlanganisa: Ukuhambisana kwempahla ye-valve yokuhlola ne-fluid medium. Ama-valve okuhlola angamadivayisi athandwayo ezilungiselelweni zezimboni ezingabizi nje kuphela futhi ezinokwethenjelwa, kodwa futhi kulula ukuzisebenzisa.Lapho uthenga i-valve yokuhlola, qiniseka ukuthi uyaziqonda izidingo zakho eziyingqayizivele futhi uhlole indlela yokukhetha i-valve.Futhi, qiniseka ukuthi uyakuqonda ukufakwa izimfuneko zokugwema izinkinga zesikhombisi-ndlela sokugeleza noma ukulimala kwesistimu yakho ngenxa yokwakheka kwengcindezi. UCharles Kolstad ube noTameson kusukela ngo-2017 futhi uvela e-United States of America.Uneziqu zeMechanical Engineering azithola e-St Thomas University, Minnesota, USA.Usebenza kude ngenkathi ehamba eYurophu, e-Asia nase-Americas. uyavakashela indlunkulu kaTameson ngezikhathi ezithile ukuze ahlangane namalungu amasha eqembu futhi asebenze ehhovisi.
