Isibonelo sokuqala esifana ne-ivalvu yebholayivalvu enelungelo lobunikazi likaJohn Warren ngo-1871. Iyivalvu ehlezi ngensimbi enebhola lethusi kanye nesihlalo sethusi. Ekugcineni uWarren wanika uJohn Chapman, inhloko yeChapman Valve Company ilungelo lakhe lobunikazi lokuklama ivalvu yebhola lethusi. Kungakhathaliseki ukuthi yisiphi isizathu, uChapman akazange afake umklamo kaWarren ekukhiqizweni. Esikhundleni salokho, yena nabanye abakhiqizi bamavalvu bebelokhu besebenzisa imiklamo emidala iminyaka eminingi.

Ama-ball valve, aziwa nangokuthi ama-ball cock valve, ekugcineni adlala indima ngesikhathi seMpi Yezwe II. Phakathi nalesi sikhathi, onjiniyela bawaklama ukuze asetshenziswe ezinhlelweni zikaphethiloli zezindiza zempi. Ngemva kwempumelelo yeamavalvu ebholaEMpini Yezwe II, onjiniyela basebenzise ama-ball valve ezisetshenziswa ezimbonini.

Enye yezinto ezibaluleke kakhulu eziphathelene nama-ball valve ngawo-1950 kwaba ukuthuthukiswa kwe-Teflon kanye nokusetshenziswa kwayo okulandelayo njengezinto ze-ball valve. Ngemva kokuthuthukiswa okuphumelelayo kwe-Teflon, amabhizinisi amaningi afana ne-DuPont ancintisana nelungelo lokuyisebenzisa, ngoba ayazi ukuthi i-Teflon ingaletha izinzuzo ezinkulu emakethe. Ekugcineni, izinkampani ezingaphezu kweyodwa zakwazi ukukhiqiza ama-Teflon valve. Ama-Teflon ball valve aguquguquka futhi angakha izivalo ezinhle ngezindlela ezimbili. Ngamanye amazwi, aqondene nezinhlangothi ezimbili. Aphinde angavuzi. Ngo-1958, uHoward Freeman wayengumenzi wokuqala ukuklama i-ball valve enesihlalo se-Teflon esiguquguqukayo, futhi umklamo wakhe waba nelungelo lobunikazi.

Namuhla, ama-ball valve athuthukiswe ngezindlela eziningi, okuhlanganisa ukuhambisana kwawo nezinto kanye nezinhlelo zokusebenza ezingaba khona. Ngaphezu kwalokho, bangasebenzisa imishini ye-CNC kanye nohlelo lwekhompyutha (njengemodeli ye-Button) ukwenza ama-ball valve amahle kakhulu. Maduze nje, abakhiqizi bama-ball valve bazokwazi ukunikeza izinketho eziningi zemikhiqizo yabo, okuhlanganisa ukwakhiwa kwe-aluminium, ukuguguleka okuncane kanye namakhono amakhulu okucindezela, okuvumela abaqhubi ukuthi badlulise inani eliguquguqukayo loketshezi nge-valve ngesivinini sokugeleza esilinganiselwe.

isicelo

Umgomo we-ball valve ukulawula ukugeleza koketshezi. Bangakwenza lokhu ngezindlela eziningi. Bangalungisa izinhlobo ezithile zama-valve okugeleza okuphansi, bahlinzeke ngokuvimbela ukugeleza emuva kwama-valve nge-swing check assemblies, bahlukanise uhlelo, futhi bahlinzeke ngokuvalwa okuphelele kwabaqhubi begiya.

Ngenxa yokuthi zingalawulwa ngesandla noma ngogesi, ama-ball valve angasebenza ngezilungiselelo ezahlukahlukene.

Ezimweni eziningi, ama-ball valve asetshenziselwa ukuvula nokuvala amapayipi aqukethe izinto eziqinile ezilengisiwe, ama-slurry, uketshezi noma amagesi. Ezinye izinhlelo lapho ama-ball valve evame ukusetshenziswa khona zifaka phakathi izinhlelo zamapayipi, imishini, namathuluzi cishe kuzo zonke izimboni ezithutha uketshezi. Ungawathola noma kuphi kusukela phansi efektri kuya empompini ekhaya lakho. Izimboni ezisebenzisaamavalvu ebholakufaka phakathi ukukhiqiza, izimayini, uwoyela negesi, ezolimo, ukushisa nokupholisa, amapayipi ezimboni nawasekhaya, amanzi, izimpahla ezisetshenziswayo, ukwakhiwa, njll.
