Ngesonto eledlule, ifektri yaqeda umsebenzi wokukhiqiza inqwaba yensimbiivalvu yebhabhathaneIzinto zokwakha zaziyinsimbi ebunjiwe, futhi ivalvu ngayinye yayinedivayisi yesondo lesandla, njengoba kuboniswe esithombeni esilandelayo.

Iivalvu yebhabhathane emithathu engavamileifinyelela ukuvala okuphumelelayo ngesakhiwo esiyingqayizivele. Lapho isikhungo sokujikeleza sepuleti le-valve (okungukuthi, isikhungo somshaft) siphambuka emgqeni ophakathi womzimba we-valve, sakha ubungqabavu bokuqala. Umugqa ophakathi wobuso bokuvala bepuleti le-valve uphambuka emgqeni ophakathi womzimba we-valve, kwakha ubungqabavu besibili. Ubuso bokuvala besihlalo se-valve buklanywe ngesimo esiyindilinga, ukuze ubuso bokuvala bepuleti le-valve kanye nobuso bokuvala besihlalo se-valve bakhe i-Engela ethile. Lokhu ubungqabavu besithathu.

Uma uvula ivalvu, ipuleti levalvu, ngaphansi kokusebenza kwedivayisi yokushayela, liqala lisuke endaweni yokuvala yesihlalo sevalvu bese lijikeleza ukuze kuncishiswe ukungqubuzana. Uma ivaliwe, ngemva kokuba ipuleti levalvu lijikelezile endaweni yalo, ngaphansi kwengcindezi yendawo noma amandla edivayisi yokushayela, linamathela eduze endaweni yokuvala yesihlalo sevalvu, livimbele ukugeleza kwendawo. Lo mklamo ohlanganisa izingxenye ezintathu uqinisekisa ukuthi ngesikhathi senqubo yokuvula nokuvala ivalvu, cishe akukho ukungqubuzana phakathi kwepuleti levalvu kanye nendawo yokuvala yesihlalo sevalvu, ngaleyo ndlela kwandise impilo yesevisi. Okwamanje, lingafinyelela ukumelana nengcindezi yezinhlangothi ezimbili futhi lisebenza kahle ekuvaleni.

Izimo lapho ama-valve e-butterfly e-eccentric amathathu ase-China asetshenziswa kabanzi:

1. Insimu ye-Petrochemical: Emayunithi okuqhekeka kwe-catalytic ezindawo zokuhlanza uwoyela, isetshenziselwa ukulawula uwoyela oshisa kakhulu, ocindezela kakhulu kanye ne-gas media equkethe ukungcola kwezinhlayiya ukuqinisekisa ukusebenza okuzinzile kweyunithi; Ekukhiqizweni kwamakhemikhali, lapho kuthuthwa izixazululo ze-asidi ne-alkali ezibola kakhulu, isakhiwo sayo esikhethekile sokuvala singavimbela ngempumelelo ukuvuza okuphakathi futhi siqinisekise ukuphepha kokukhiqiza.

2. Imboni yamandla: Ohlelweni lwepayipi lomusi lwezitshalo zamandla ezishisayo, ivalvu yebhabhathane ephindwe kathathu esetshenziswa ngesandla (ivalvu yebhabhathane yegiya le-worm) ingazivumelanisa nezimo zokusebenza zokuvulwa nokuvalwa njalo komusi okushisa okuphezulu futhi ilawule ngokunembile ukugeleza komusi. Ohlelweni lokupholisa lwesiqhingi senuzi sesitshalo samandla enuzi, ngokuthembeka okuphezulu nokusebenza kokuvala, ukulethwa okuphephile kwesibandisi kuyaqinisekiswa futhi ukuvuza kwezinto ezinemisebe kuyavinjelwa.

3. Ukuhlinzekwa kwamanzi kanye nokuthuthwa kwamanzi emadolobheni: Amapayipi okukhipha indle ezitshalo ezinkulu zokuhlanza indle anganqamula indle equkethe amanzi amaningi ukuze kuvinjelwe ukungcoliswa kokubuyela emuva. Asetshenziswa emapayipini amakhulu ohlelo lokuhlinzeka ngamanzi emadolobheni ukuze kunqanyulwe ukugeleza kwamanzi ngokushesha, kube lula ukuhlolwa nokugcinwa kwamapayipi, kanye nokuqinisekisa ukuzinza kokuhlinzekwa kwamanzi emadolobheni.

4. Imboni yensimbi: Amapayipi egesi esithando sokuqhuma ezigayweni zensimbi angafinyelela ukuvalwa okuthembekile ezindaweni ezinzima ezinomfutho ophezulu nothuli, alawule ngempumelelo ukugeleza kwegesi, futhi anikeze amandla azinzile okuncibilikisa isithando sokuqhuma.
