Ngesonto eledlule, ifektri yaqeda umsebenzi wokukhiqiza inqwaba yensimbiuvemvane valve. Impahla yayiyinsimbi, futhi i-valve ngayinye yayifakwe isondo lesandla, njengoba kuboniswe esithombeni esilandelayo.

Ii-valve yama-butterfly amathathuifinyelela uphawu olusebenzayo ngesakhiwo esiyingqayizivele. Lapho isikhungo sokuzungezisa se-valve plate (okungukuthi, isikhungo se-shaft) sichezuka emgqeni omaphakathi womzimba we-valve, sakha i-eccentricity yokuqala. Umugqa omaphakathi wendawo yokuvala yepuleti levalvu uyachezuka emgqeni omaphakathi womzimba wevalvu, wenze i-eccentricity yesibili. Indawo yokuvala yesihlalo se-valve iklanywe ngendlela eyi-conical, ukuze indawo yokuvala ye-valve plate kanye nendawo yokuvala yesihlalo se-valve yakhe i-Engeli ethile. Lokhu kuwukungahlukanisi kwesithathu.

Lapho uvula i-valve, ipuleti le-valve, ngaphansi kwesenzo sedivayisi yokushayela, iqala ngokuphuma endaweni yokuvala yesihlalo se-valve bese ijikeleza ukuze kuncishiswe ukungqubuzana. Uma ivaliwe, ngemva kokuba ipuleti le-valve lizungeza endaweni, ngaphansi kwengcindezi ye-medium noma amandla edivayisi yokushayela, linamathela eduze kwendawo yokuvala yesihlalo se-valve, ivimbe ukugeleza kwe-medium. Lo mklamo onama-eccentric amathathu uqinisekisa ukuthi phakathi nenqubo yokuvula nokuvala i-valve, cishe akukho ukungqubuzana phakathi kwepuleti le-valve nendawo yokuvala isihlalo se-valve, ngaleyo ndlela andise impilo yesevisi. Ngaleso sikhathi, ingafinyelela ukumelana nengcindezi ye-bidirectional futhi ibe nokusebenza okuhle kokuvala.

Izimo lapho ama-valve uvemvane angama-triple eccentric asetshenziswa kabanzi:

1. Inkambu ye-petrochemical: Ezingxenyeni ze-catalytic cracking zezindawo zokuhluzwa uwoyela, isetshenziselwa ukulawula izinga lokushisa eliphezulu, i-high-pressure oil and gas media equkethe ukungcola okuyizinhlayiyana ukuze kuqinisekiswe ukusebenza okuzinzile kweyunithi; Ekukhiqizeni amakhemikhali, lapho kuthuthwa izixazululo ze-asidi egqwalile kakhulu kanye ne-alkali, isakhiwo saso esikhethekile sokuvala singavimbela ngempumelelo ukuvuza okuphakathi futhi siqinisekise ukuphepha kokukhiqiza.

2. Imboni yamandla: Ohlelweni lwepayipi lesitimu lezitshalo zamandla ashisayo, ivalve yovemvane ene-eccentric ephindwe kathathu (i-worm gear butterfly valve) ingajwayelana nezimo zokusebenza zokuvula nokuvalwa njalo kwesitimu esinezinga lokushisa eliphezulu futhi ilawule ngokunembile ukugeleza kwesitimu. Ohlelweni lokupholisa lwesiqhingi senuzi sesikhungo samandla enuzi, enokwethenjelwa okuphezulu nokusebenza kokuvala, ukulethwa okuphephile kwezinto ezipholile kuyaqinisekiswa futhi ukuvuza kwezinto ezikhipha imisebe kuyavinjelwa.

3. Ukuhlinzekwa kwamanzi emadolobheni kanye nokukhipha indle: Amapayipi okulahla indle ezikhungweni ezinkulu zokukhuculula indle anganqamula indle egcwele kakhulu ukuvimbela ukungcoliswa kokubuyela emuva. Isetshenziswa emapayipini amakhulu ohlelo lokuphakelwa kwamanzi emadolobheni ukunqamula ngokushesha ukugeleza kwamanzi, ukwenza lula ukuhlolwa nokugcinwa kwamapayipi, kanye nokuqinisekisa ukuzinza kokuhlinzekwa kwamanzi emadolobheni.

4. Imboni ye-Metallurgical: Amapayipi egesi esithandweni somlilo ezigayweni zensimbi angafinyelela ukuvalwa okuthembekile ezindaweni ezinomfutho omkhulu nothuli, alawule ngokuphumelelayo ukugeleza kwegesi, futhi anikeze amandla azinzile okuncibilikisa isithando somlilo.
