1. Ii-valve yebholauvela ku-valve yepulaki.Ingxenye yayo yokuvula neyokuvala isebenza njengendilinga, esebenzisa i-sphere ukuzungezisa ama-degree angama-90 ezungeze i-axis yesiqu se-valve ukufeza inhloso yokuvula nokuvala.
2. Umsebenzi we-valve yebhola
I-valve yebhola isetshenziselwa kakhulu ukusika, ukusabalalisa kanye nokushintsha isiqondiso sokugeleza kwe-medium epayipini.I-valve yebhola eklanywe njengokuvula okumise okwe-V nayo inomsebenzi omuhle wokulungisa ukugeleza.
I-valve yebhola ayilula nje kuphela ngesakhiwo, inhle ekusebenzeni kokuvala, kodwa futhi incane ngosayizi, ilula ngesisindo, ukusetshenziswa okuphansi kwezinto ezibonakalayo, okuncane ngosayizi wokufaka, kanye ne-torque encane yokushayela ngaphakathi kwebanga elithile lokudlula.Kulula ukuyisebenzisa futhi kulula ukuyifinyelela ukuvulwa nokuvala ngokushesha.Enye yezinhlobo zama-valve ezikhula ngokushesha eminyakeni engaphezu kweyishumi.Ikakhulukazi emazweni athuthukile njengaseMelika, eJapane, eJalimane, eFrance, e-Italy, eNtshonalanga, naseBrithani, ukusetshenziswa kwama-valve ebhola kukhulu kakhulu, futhi izinhlobonhlobo nenani lokusetshenziswa kuyaqhubeka kwanda.Impilo, ukusebenza okuhle kakhulu kokulawula kanye nokuthuthukiswa kwe-valve enemisebenzi eminingi, ukwethembeka kwayo nezinye izinkomba zokusebenza sekufinyelele izinga eliphezulu, futhi sekushintshe ingxenye yamavalvu esango, ama-stop valves, nama-valve alawulayo.
Ngokuthuthuka kobuchwepheshe be-valve yebhola, esikhathini esifushane esibonakalayo, kuzoba nokusetshenziswa okubanzi kwamapayipi kawoyela negesi, amayunithi okuhluzwa uwoyela kanye nokuqhekeka, kanye nemboni yenuzi.Ngaphezu kwalokho, ama-valve amabhola azophinde abe olunye lwezinhlobo zamavalvu ezihamba phambili kumakhaliba amakhulu naphakathi nendawo kanye nezinkundla ezinomfutho ophansi nophakathi kwezinye izimboni.
Izinzuzo ezi-3 ze-valve yebhola
Inokumelana nokugeleza okuphansi kakhulu (empeleni uziro)
Ngenxa yokuthi ngeke ibambeke ngesikhathi somsebenzi (uma ingekho into yokuthambisa), ingasetshenziswa ngendlela ethembekile emithonjeni edlayo kanye noketshezi olubilisa kancane.
Ngomfutho omkhulu kanye nobubanzi bokushisa, uphawu oluphelele lungafinyelelwa.
Ingabona ukuvulwa nokuvala okusheshayo, futhi isikhathi sokuvula nokuvala kwezinye izakhiwo yi-0.05-0.1s kuphela ukuqinisekisa ukuthi ingasetshenziswa ohlelweni oluzenzakalelayo lwebhentshi lokuhlola.Lapho uvula futhi uvala i-valve ngokushesha, akukho ukushaqeka ekusebenzeni.
Isakhiwo se-valve yebhola
Indawo yokusebenza ivalwe ngokuthembekile nhlangothi zombili.
Uma ivuleke ngokugcwele futhi ivaleke ngokugcwele, indawo yokuvala yebhola kanye nesihlalo sevalvu ihlukaniswa nephakathi, ngakho-ke okuphakathi okudlula kuvalvu ngesivinini esikhulu ngeke kubangele ukuguguleka kwendawo yokuvala.
Ngesakhiwo esihlangene nesisindo esincane, singabhekwa njengesakhiwo se-valve esinengqondo kunazo zonke zezinhlelo zemidiya ye-cryogenic.
Umzimba we-valve uno-symmetrical, ikakhulukazi uma isakhiwo somzimba we-valve sishiselwe, esingamelana kahle nengcindezi yepayipi.
Isiqephu sokuvala singamelana nomehluko wengcindezi ephezulu uma sivaliwe.
I-valve yebhola enomzimba oboshwe ngokugcwele ingangcwatshwa ngokuqondile emhlabathini, ukuze izingxenye zangaphakathi ze-valve zingagqwali, futhi impilo yesevisi ephezulu ingafinyelela iminyaka engu-30.Yivalvu ekahle kakhulu yamapayipi kawoyela negesi yemvelo.
Ngenxa yokuthi i-valve yebhola inezinzuzo ezingenhla, inezinhlobonhlobo zezicelo.I-valve yebhola ingasetshenziswa ku-: i-passage encane isuka ku-8mm kuya ku-1200mm.
Umfutho ojwayelekile usukela ku-vacuum kuye ku-42MPa kanti izinga lokushisa lokusebenza lisukela ku- -204°C kuya ku-815°C.
