1. Iivalvu yebholaisuka ku-valve yepulaki. Ingxenye yayo yokuvula nokuvala isebenza njengembulunga, esebenzisa imbulunga ukujikeleza ama-degree angu-90 ezungeze i-axis yesiqu se-valve ukuze kufezwe injongo yokuvula nokuvala.
2. Umsebenzi we-ball valve
Ivalvu yebhola isetshenziswa kakhulu ekunqumeni, ekusabalaliseni nasekushintsheni indlela yokugeleza kwe-medium epayipini. Ivalvu yebhola eklanywe njengokuvulwa okunobume obungu-V nayo inomsebenzi omuhle wokulungisa ukugeleza.
I-valve yebhola ayilula nje kuphela ngesakhiwo, inhle ekusebenzeni kokuvala, kodwa futhi incane ngosayizi, ilula ngesisindo, iphansi ekusetshenzisweni kwezinto ezibonakalayo, incane ngosayizi wokufaka, futhi incane nge-torque yokushayela ngaphakathi kobubanzi obuthile bokudlula. Kulula ukuyisebenzisa futhi kulula ukuyifinyelela ekuvulekeni nasekuvaleni okusheshayo. Enye yezinhlobo zama-valve ezikhula ngokushesha eminyakeni engaphezu kweyishumi. Ikakhulukazi emazweni athuthukile njenge-United States, iJapan, iJalimane, iFrance, i-Italy, iNtshonalanga, neBrithani, ukusetshenziswa kwama-valve ebhola kubanzi kakhulu, futhi ukuhlukahluka nobuningi bokusetshenziswa kuyaqhubeka nokukhula. Impilo, ukusebenza okuhle kakhulu okulawulayo kanye nokuthuthukiswa kwe-valve okunemisebenzi eminingi, ukuthembeka kwayo kanye nezinye izinkomba zokusebenza kufinyelele ezingeni eliphakeme, futhi kuthathe indawo yama-valve esango, ama-valve okuma, kanye nama-valve okulawula ngokwengxenye.
Ngokuthuthuka kobuchwepheshe bama-ball valve, esikhathini esifushane esizayo, kuzoba nokusetshenziswa okubanzi kakhulu kumapayipi kawoyela negesi, amayunithi okuhluza nokuqhekeka kawoyela, kanye nemboni yenuzi. Ngaphezu kwalokho, ama-ball valve nawo azoba olunye lwezinhlobo zama-valve ezihamba phambili kuma-calibers amakhulu naphakathi kanye namasimu anengcindezi ephansi nephakathi kwezinye izimboni.
Izinzuzo ezi-3 ze-ball valve
Inokumelana nokugeleza okuphansi kakhulu (empeleni u-zero)
Ngenxa yokuthi ngeke ibambeke ngesikhathi somsebenzi (uma kungekho lubricant), ingasetshenziswa ngokuthembekile ezintweni ezibolayo kanye noketshezi olubila kancane.
Ebangeni elikhulu lokucindezela kanye nokushisa, kungafinyelelwa ukuvalwa okuphelele.
Ingakwazi ukuvula nokuvala ngokushesha, futhi isikhathi sokuvula nokuvala kwezinye izakhiwo singu-0.05-0.1s kuphela ukuqinisekisa ukuthi ingasetshenziswa ohlelweni oluzenzakalelayo lwebhentshi lokuhlola. Lapho ivula futhi ivala ivalvu ngokushesha, akukho ukushaqeka okusebenzayo.
Isakhiwo se-ball valve
Indawo yokusebenza ivalwe ngokuthembekile kuzo zombili izinhlangothi.
Uma ivuliwe futhi ivaliwe ngokuphelele, indawo yokuvala ibhola kanye nesihlalo sevalvu kuhlukaniswe nendawo yokuvala, ngakho indawo yokuvala edlula kuvalvu ngesivinini esikhulu ngeke ibangele ukuguguleka kwendawo yokuvala.
Njengoba inesakhiwo esincane kanye nesisindo esincane, ingabhekwa njengesakhiwo se-valve esinengqondo kakhulu sezinhlelo zemidiya ye-cryogenic.
Umzimba we-valve ulingana, ikakhulukazi uma isakhiwo somzimba we-valve sishisiwe, esingamelana kahle nokucindezeleka okuvela epayipini.
Ingxenye yokuvala ingamelana nomehluko wokucindezela okuphezulu uma ivaliwe.
Ivalvu yebhola enomzimba ohlanganisiwe ngokugcwele ingangcwatshwa ngqo emhlabathini, ukuze izingxenye zangaphakathi zevalvu zingagqwali, futhi isikhathi esiphezulu senkonzo singafinyelela eminyakeni engama-30. Iyivalvu efanelekile kakhulu yamapayipi kawoyela negesi yemvelo.
Ngenxa yokuthi ivalvu yebhola inezinzuzo ezingenhla, inezinhlelo zokusebenza eziningi ezahlukene. Ivalvu yebhola ingasetshenziswa: indlela evamile isukela ku-8mm kuya ku-1200mm.
Ingcindezi evamile isukela ku-vacuum cleaner iye ku-42MPa kanti izinga lokushisa lokusebenza lisukela ku--204°C kuya ku-815°C.
