Ukusuka kuwoyela negesi kuye ezindaweni zokuhlanza amanzi namanzi angcolile, amavalvu adlala indima ebalulekile ekulawuleni ukugeleza koketshezi ezimbonini.Olunye uhlobo lwesivalo oluye lwanakwa kabanzi eminyakeni yamuva nje ivalve uvemvane oluyi-triple eccentric.Idizayinelwe ukuhlinzeka ngesilawuli sokugeleza esithembekile nesinembayo, le valve esungulayo inikeza izinzuzo eziningi ngaphezu kwamavalvu ovemvane bendabuko.Kulesi sihloko, sizohlola izici, izinzuzo kanye nokusetshenziswa kwama-valve evemvane eccentric kathathu.

I-valve uvemvane oluyi-eccentric kathathu ithola igama ekwakhiweni kwayo okuyingqayizivele okuhlanganisa ama-eccentricities amathathu.Lawa ma-offsets yibanga eliphakathi kwe-centerline yesihlalo kanye ne-shaft centerline, i-bore centerline, ne-valve centerline.Lo mklamo uvumela i-disc ukuthi ijikeleze kahle futhi ivaleke ngokuqinile esihlalweni ukuze ingavuzi.

Ngokungafani nama-valve ovemvane bendabuko lapho i-disc igudla khona esihlalweni ngesikhathi sokusebenza, i-valve ye-butterfly eccentric kathathu iqeda ukungqubuzana ngokuqondisa i-disc nesihlalo ngama-engeli ahlukene.Lo mklamo omusha wehlisa ukuguga, unweba isikhathi se-valve futhi unciphise izindleko zokuyilungisa.

Inzuzo eyinhloko ye-valve ye-butterfly eccentric kathathu ikhono layo lokuvala uphawu lwe-hermetic.Isigxivizo esiqinile esitholwe yile valve sivimbela noma yikuphi ukuvuza okungafuneki, okuhlinzeka ngezinga eliphakeme lokuphepha nokuthembeka.Lesi sici siyenza ifaneleke ezinhlelweni zokusebenza lapho ukuvuza kungabangela izingozi zemvelo noma ubungozi obukhulayo bokuhluleka kwemishini.

Enye inzuzo enkulu yamavalve evemvane eccentric kathathu yikhono lawo lokumelana nezinga lokushisa eliphezulu nezingcindezi.Idizayini nezinto zokwakha zale valve ziyenza ifanele izimboni eziphatha uketshezi olushisa kakhulu, njengezimboni zokuphehla amandla kanye nezimboni ze-petrochemical.Ukwakhiwa kwayo okuqinile kuqinisekisa ukuthi ingakwazi ukubhekana nezingcindezi ezihlukene kakhulu, okuyenza ibe ukukhetha okuhle kakhulu kwezicelo ezifunayo.

Ngaphezu kwalokho, i-valve ye-butterfly eccentric kathathu inokunemba okuhle kakhulu kokulawula.Nge-geometry yesihlalo esinembile kanye nomklamo we-offset, i-valve inikeza ukulawulwa kokugeleza okuhle kakhulu, ngisho nasekugelezeni okuphansi.Lokhu kulawula okunembayo kukhulisa ukusebenza kahle kwenqubo futhi kunciphisa ukumosheka kwamandla.

Ukuguquguquka kwe-valve butterfly eccentric kathathu kungenye inzuzo okungafanele inganakwa.Idizayini yayo ehlangene, engasindi yenza kube lula ukuyifaka kumasistimu wamapayipi ahlukahlukene.Ngaphezu kwalokho, ingasetshenziswa ngezindlela zemanuwali nezizenzakalelayo kuye ngezidingo zohlelo lokusebenza.

Ama-valve emvemvane eccentric kathathu asetshenziswa kakhulu kuwoyela negesi, amakhemikhali, ukukhiqiza amandla, izindawo zokuhlanza amanzi namanzi angcolile nakwezinye izimboni.Ngokujwayelekile isetshenziswa kumapayipi egesi nawuketshezi, ilawula kahle ukugeleza futhi ihlukanise izingxenye zepayipi ukuze zilungiswe.Ikhono layo lokuphatha uketshezi lokushisa eliphezulu liyenza ifanelekele isitshalo samandla ashisayo kanye nezicelo zokucwenga.Ukwengeza, isetshenziswa kabanzi ezindaweni zokuhlanza amanzi ukulawula ukugeleza kwamanzi ngesikhathi sokuhlanza, ukukhishwa kwe-disinfection nokusabalalisa.

Sengiphetha, i-valve ye-butterfly eyi-triple eccentric iyintuthuko ebalulekile yezobuchwepheshe emkhakheni wokulawula ukugeleza.Ngomklamo wayo oyingqayizivele, iqinisekisa ukubekwa uphawu kwe-hermetic, ukunemba okuhle kakhulu kokulawula kanye nekhono lokusingatha izinga lokushisa eliphezulu nezingcindezi.Ukuguquguquka kwayo kanye nokulula kokufakwa kwayo kunezela ekuthandeni kwayo.Amavalvu ovemvane okuthathu abonakala eyithuluzi eliyigugu njengoba izimboni ziqhubeka nokufuna izixazululo eziphumelelayo nezithembekile zokulawula ukugeleza.
