Kusukela ku-oyela negesi kuya ezitshalweni zokuhlanza amanzi namanzi angcolile, ama-valve adlala indima ebalulekile ekulawuleni ukugeleza koketshezi kuzo zonke izimboni. Uhlobo olulodwa lwe-valve oluye lwathola ukunakwa kabanzi eminyakeni yamuva nje yi-valve ye-butterfly eccentric kathathu. Yakhelwe ukunikeza ukulawula ukugeleza okuthembekile nokunembile, le valve entsha inikeza izinzuzo eziningi ngaphezu kwama-valve e-butterfly endabuko. Kulesi sihloko, sizohlola izici, izinzuzo kanye nokusetshenziswa kwama-valve e-butterfly eccentric kathathu.

I-valve ye-butterfly engavamile kathathu ithola igama layo ngenxa yomklamo wayo oyingqayizivele ohlanganisa izinto ezintathu ezingavamile. Lezi ziphazamiso yibanga eliphakathi komugqa ophakathi wesihlalo nomugqa ophakathi weshaft, umugqa ophakathi we-bore, kanye nomugqa ophakathi we-valve. Lo mklamo uvumela idiski ukuthi ijikeleze kahle futhi ivale ngokuqinile esihlalweni ukuze kungabikho ukuvuza.

Ngokungafani namavalvu emvemvane endabuko lapho idiski ikhuhla khona isihlalo ngesikhathi sokusebenza, ivalvu yemvemvane engavamile kathathu iqeda ukungqubuzana ngokuvumelanisa idiski nesihlalo ngama-engeli ahlukene. Lo mklamo omusha unciphisa ukuguguleka, wandise isikhathi sokuphila kwevalvu futhi unciphise izindleko zokulungisa.

Inzuzo eyinhloko yevalvu yebhabhathane e-eccentric kathathu ikhono layo lokuvala ngaphandle komoya. Ukuvalwa okuqinile okufinyelelwa yileli valve kuvimbela noma yikuphi ukuvuza okungafuneki, okunikeza izinga eliphezulu lokuphepha nokuthembeka. Lesi sici siyenza ibe yindawo ekahle kakhulu ekusetshenzisweni lapho ukuvuza kungabangela izingozi zemvelo noma ingozi eyengeziwe yokwehluleka kwemishini.

Enye inzuzo enkulu yama-valve e-butterfly angavamile kathathu yikhono lawo lokubekezelela amazinga okushisa aphezulu kanye nokucindezela. Umklamo kanye nezinto zokwakha zale valve kuyenza ifaneleke ezimbonini ezisingatha uketshezi oluphezulu lokushisa, njengokukhiqiza ugesi kanye nezimboni ze-petrochemical. Ukwakhiwa kwayo okuqinile kuqinisekisa ukuthi ingakwazi ukubhekana nokucindezela okukhulu okuhlukile, okwenza kube ukukhetha okuhle kakhulu kwezicelo ezidinga kakhulu.

Ngaphezu kwalokho, ivalvu yebhabhathane e-eccentric kathathu inokunemba okuhle kakhulu kokulawula. Ngokwakheka kwayo okunembile kwesihlalo kanye nomklamo we-offset, ivalvu inikeza ukulawula okuhle kakhulu kokugeleza, ngisho noma ukugeleza kwayo kuphansi. Lokhu kulawula okunembile kwandisa ukusebenza kahle kwenqubo futhi kunciphisa ukuchithwa kwamandla.

Ukuguquguquka kwevalvu ye-butterfly e-eccentric kathathu kungenye inzuzo okungafanele inganakwa. Umklamo wayo omncane nolula wenza kube lula ukuyifaka ezinhlelweni ezahlukene zamapayipi. Ngaphezu kwalokho, ingasetshenziswa ngezindlela zesandla nezenzakalelayo kuye ngezidingo zohlelo lokusebenza.

Amavalvu e-butterfly angavamile amathathu asetshenziswa kabanzi ezimbonini zokuhlanza uwoyela negesi, amakhemikhali, ukukhiqizwa kukagesi, amanzi kanye namanzi angcolile kanye neminye imboni. Njengoba ivame ukusetshenziswa emapayipini egesi kanye noketshezi, ilawula kahle ukugeleza kwamanzi futhi ihlukanise izingxenye zepayipi ukuze zilungiswe. Amandla ayo okuphatha uketshezi olushisa kakhulu ayenza ifanelekele ukusetshenziswa kwezitshalo zamandla ezishisayo kanye nezindawo zokuhluza amanzi. Ngaphezu kwalokho, isetshenziswa kabanzi ezitshalweni zokuhlanza amanzi ukulawula ukugeleza kwamanzi ngesikhathi sokuhlanza, ukubulala amagciwane kanye nokusatshalaliswa.

Ekuphetheni, ivalvu yebhabhathane e-eccentric kathathu iyintuthuko ebalulekile kwezobuchwepheshe emkhakheni wokulawula ukugeleza. Ngomklamo wayo oyingqayizivele, iqinisekisa ukuvalwa kwe-hermetic, ukunemba okuhle kakhulu kokulawula kanye nekhono lokusingatha amazinga okushisa aphezulu kanye nokucindezela. Ukuguquguquka kwayo kanye nokulula kokufakwa kwayo kunezela ekukhangeni kwayo. Amavalvu ebhabhathane e-Triple offset abonakala eyithuluzi elibalulekile njengoba izimboni ziqhubeka nokufuna izixazululo zokulawula ukugeleza ezisebenza kahle nezithembekile.
