I-valve yebhola iyithuluzi elijikelezayo lekota yokujika elilawula ukugeleza koketshezi namagesi ngokusebenzisa ipayipi ngokusebenzisa i-disc eyindilinga ejikelezayo, eyaziwa ngokuthi ibhola. Leli bhola linembobo emaphakathi, noma i-port, ehambisana nokuvuleka kwepayipi lapho i-valve isesimweni esivulekile, ivumela uketshezi ukuthi lugeleze ngokukhululeka ohlelweni. Lapho isibambo noma i-actuator ijikwa ama-degree angamashumi ayisishiyagalolunye, ingxenye eqinile yebhola iyajikeleza ukuze ivimbe umgudu ngokuphelele, idale uphawu oluqinisekile olumisa ukugeleza cishe ngaso leso sikhathi. Izingxenye eziyisisekelo zanoma iyiphi i-valve yebhola zihlanganisa umzimba, ibhola ngokwalo, izihlalo ze-valve, isiqu, kanye nohlobo oluthile lwesibambo noma indlela yokusebenzisa ehambisa ukunyakaza kokujika ebholeni. Ngenxa yalokhu kwakhiwa okulula okuhle, i-valve yebhola iletha ukusebenza okuthembekile ngezingxenye ezimbalwa ezihambayo, okuhumushela ngqo ezindlekweni eziphansi zokunakekela kanye nempilo yokusebenza ende.

Umthetho wokusebenza ngemuva kokusebenza kwe-quarter-turn yilokho okuhlukanisa ama-ball valve kwezinye izinto zokulawula ukugeleza njengama-gate valve noma ama-globe valve. I-gate valve evamile kumele iphendulwe izikhathi eziningi ukuze ivulwe noma ivalwe, kanti i-ball valve ifinyelela ukuvalwa okuphelele ngokujikeleza okukodwa kwama-degree angamashumi ayisishiyagalolunye, okwenza ifanelekele izinhlelo ezidinga ukuvalwa okuphuthumayo ngokushesha. Ngaphezu kwalokhu kukwazi ukuvala ngokushesha, i-ball valve inikeza ukuvala okuqinile, okungangeni moya lapho ivalwe ngokuphelele, ngisho nangemva kweminyaka yokusetshenziswa kanzima, ngenxa yezinto eziguquguqukayo zezihlalo ezicindezela ngokuqinile ebusweni be-polished ball. Uma kuqhathaniswa nama-butterfly valve, ama-ball valve ngokuvamile anikeza indlela yokugeleza eqondile kanye nokwehla kwengcindezi okuphansi, futhi uma kuqhathaniswa nama-globe valve, amancane kakhulu futhi alula ukuwasebenzisa. Lezi zinzuzo ezihlanganisiwe zokusebenza ngokushesha, ukuvala okuthembekile, ukunakekela okuphansi, kanye nomklamo oqondile kuchaza ukuthi kungani ama-ball valve esephenduke enye yezinhlobo zamavalvu ezicaciswa kakhulu ezinhlelweni zamapayipi ezimbonini, ezohwebo, nasezindaweni zokuhlala emhlabeni wonke.

Akubona wonke ama-valve ebhola akhiwe ngendlela efanayo, futhi ukuqonda umehluko phakathi kwezinhlobo eziyinhloko kubalulekile ukuze ukhethe iyunithi efanele yohlelo oluthile. Onjiniyela bakhe izinhlobonhlobo ezimbalwa zomklamo oyisisekelo we-valve yebhola ukuze babhekane nezinga lokucindezela elihlukene, izidingo zokulawula ukugeleza, nezimo zokusebenza. Izigaba ezine ezivame kakhulu yilezi: i-floating ball valve, i-trunnion mounted ball valve, i-rising stem ball valve, ne-V-port ball valve, ngayinye inokwakheka okukhethekile kanye namandla athile ayenza ifanele izindawo zezimboni ezithile.

I-floating ball valve iwuhlobo lwe-ball valve olusetshenziswa kakhulu nolulula kakhulu, okuqanjwe ngayo ngenxa yendlela ibhola elihlala ngayo ngokukhululeka emzimbeni we-valve lilenga phakathi kwezihlalo ezimbili ze-elastomeric noma ze-polymeric. Kulomklamo, ibhola aliboshelwe esiqwini (stem) kodwa likhululekile ukuthi linyakaze kancane liye phansi (downstream) lapho kufakwa ingcindezi, futhi lokho kunyakaza kucindezela ibhola liqine ngasohlangothini lwesihlalo esingaphansi (downstream seat) ukuze kwakheke uphawu oluthembekile lokuvula nokuvala. Ngenxa yokuthi indlela yokuhlala (seating mechanism) incike kwingcindezi yepayipi (line pressure) ukuze ithole ukuvala, ama-floating ball valves asebenza kahle kakhulu ezimweni ezingaphansi noma eziphakathi nendawo zengcindezi, ngokuvamile afinyelela ku-ANSI class 600. Lawa ma-valve avame ukutholakala ezinhlelweni zokuhlinzeka ngamanzi, emigqeni yokucubungula amakhemikhali, nasezinsizeni ezijwayelekile zokusebenzisa lapho ukonga izindleko nokusebenza okuthembekile kubaluleke kakhulu kunamandla okumelana nengcindezi ephezulu kakhulu. Ukumiswa kwe-floating kunikeza isikhala esincane, ukulungiswa okulula, kanye nenani elingabizi kakhulu, okwenza kube ukukhetha okuyisisekelo ezifakweni eziningi zamapayipi ajwayelekile.

Kwezinhlelo ezinomfutho ophezulu nobubanzi obukhulu, i-trunnion mounted ball valve iyisixazululo esikhethwayo futhi ngezinye izikhathi siyimpoqo, ngoba yengeza ukusekelwa kwemishini okwengeziwe ukuze ibambe ibhola endaweni eqondile. Ku-trunnion style ball valve, ibhola liboshwe yi-trunnion phezulu naphansi, ngakho-ke alikwazi ukuntanta liye phansi ngomfutho, okunciphisa kakhulu i-torque yokusebenza edingekayo ngisho nasemfuthweni wepayipi ophezulu kakhulu. Lokhu kwakhiwa kwebhola eliqondile nakho kunciphisa ingcindezi nokugqokwa kwezihlalo, okwenza i-valve ikwazi ukuphatha izimo ezinzima njengokudluliswa kukawoyela negesi, ukuhlanza amapayipi (pipeline pigging), kanye nemisebenzi yokuhlukanisa imibhobho emikhulu. Izivalo eziningi ze-trunnion mounted ball valves zakhiwe ngekhono le-double block & bleed, okusho ukuthi i-valve ingahlukanisa umfutho wepayipi kanyekanye emaceleni womabili—ngaphezulu nangaphansi—kuyilapho ivumela noma yimuphi umfutho ogcwele emgodini ukuba ukhishwe ngokuphephile. Lesi sici se-double block & bleed sibaluleke kakhulu ezinsizeni ezinoketshezi oluyingozi, lapho ochwepheshe bedinga isiqinisekiso esiphelele sokuthi akukho uketshezi olungangena endaweni yokulungisa, futhi iyisizathu esikhulu sokuthi ama-trunnion valves abuse ekufakweni okubalulekile emkhakheni wamandla.

I-valve yebhola enesiqu esikhuphukayo, eyaziwa nangokuthi isiqu esikhuphukayo noma i-valve yebhola yesitayela "RR", iwuhlobo olukhethekile oluhlanganisa izinzuzo zokuvala kwe-valve yebhola nokucaca okubonakalayo kwe-valve yegeyithi enesiqu esikhuphukayo. Lapho umsebenzisi ephendula isondo lesandla, isiqu siyakhuphuka ngaphambi kokuthi siphendule ibhola, okukhuphula ibhola kancane lisuke ezihlalweni ngaphambi kokunyakaza okuphendukayo kwangempela. Lesi senzo sokuphakamisa sihlukanisa ibhola esihlalweni ngaphambi kokuthi kuphenduke, okunciphisa kakhulu ukugqokwa kwezihlalo nokulimala kokungqubuzana okungafinyeza impilo yamavalvu ebhola avamile emisebenzini yokuphindaphinda njalo. Umklamo wesiqu esikhuphukayo ulungele ukunciphisa ukugeleza kanye nezinhlelo ezidinga ukusebenza okuphindaphindayo njalo, ngoba ukugqokwa kokuvula okuncishisiwe kuqinisekisa ukuvala okuqinile okungaguquki ezinkulungwaneni zemijikelezo. Abasebenzisi nabo bayakuthokozela ukubonakala okungaqondakali kokuma kwe-valve, ngoba ukuphakama kwesiqu esikhuphukayo kuveza ngokushesha ukuthi i-valve ivuliwe noma ivaliwe noma ngabe ukude. Amavalvu ebhola anesiqu esikhuphukayo avame ukusetshenziswa eziteshini zokugcina zamapayipi, emisebenzini yokuhlanza amapayipi, kanye nezinhlelo ezinzima lapho ubude bempilo nokucaca kokuma kubaluleke kakhulu.

Ezinhlelweni ezidinga ukulawula ukugeleza okunembile nokushintshwa kwezinga kune-okulula nje kokuvula nokuvala, i-valve yebhola ye-V-port inikeza isixazululo esihle sobunjiniyela esivala igebe phakathi kwe-valve yebhola ejwayelekile ne-valve yokulawula. Esikhundleni somgodi oyindilinga, ibhola ekwakhiweni kwe-V-port linomphetho omise okwe-V noma ukuvuleka okubunjwe ngendlela ethile okuqala ukunciphisa ukugeleza kancane kancane njengoba ibhola lijikeleza, okunika umsebenzisi ukulawula okunembile ngezinga lokugeleza kwemidiya. Umgodi omise okwe-V udala isici sokugeleza esilinganayo noma esiqondile, okuvumela i-valve ukuthi inikeze ukusebenza okunembile kokunciphisa ngenkathi igcina ukuvala okuqinile okwaziwa ngakho amavalvu ebhola. Lawa mavalvu asetshenziswa kabanzi ekukhiqizweni kwepulasitiki nephepha, ekuhlanzweni kwamanzi angcolile, nasekucubungulweni kokudla, lapho ukugcina izinga lokugeleza elingaguquki kubalulekile ekhwalithini yomkhiqizo nasekuzinzeni kwenqubo. Ngenxa yokuthi ukwakheka kwe-V-port nakho kunikeza isenzo esihle sokusika, i-valve ingakwazi ukuphatha izinto ezinemicu noma ezinodaka ezingavala ukuvuleka kwamavalvu ebhola ajwayelekile, okwandisa kakhulu ukusebenza kwayo ezindaweni eziyinselele zezinqubo.

Ukusebenza nokuqina kwe-ball valve kuncike kakhulu ezintweni ezikhethiwe zokwakhiwa kwayo kanye nasekubunjweni kwangaphakathi, futhi abakhiqizi bamavalvu banamuhla banikeza uhla olubanzi lwezinto zomzimba nezihlalo ukuze kufaneleke noma yimuphi umphakathi wokusebenza.

Ukukhetha okulungile kwesihlalo kuqinisekisa ukuvala okuqinile nempilo yesevisi ende ngaphansi kwezimo ezinzima zenqubo.

I-API 6D iyindinganiso yamazwe ngamazwe echaza izidingo zokuklama, ukukhiqiza, ukuhlola, kanye nemibhalo yamavalvu amapayipi, okuhlanganisa amabhola kanye namavalvu okuhlola asetshenziswa emsebenzini kawoyela negesi. Ivalvu eqinisekisiwe nge-API 6D iye yahlolwa ngokuqinile emzimbeni wayo, ukuhlola ukuvuza kwezihlalo, kanye nokuhlola ubukhulu ukuze kuqinisekiswe ukuphepha nokuthembeka. Ukukhetha ivalvu yebhola eqinisekiswe nge-API 6D kuqinisekisa ukuthi ihlangabezana namazinga aphezulu kakhulu obuqotho embonini.

Yebo, ivalvu ye-PVC inikeza ukumelana okuhle kakhulu nezinhlobonhlobo zama-asidi, ama-alkali, namakhemikhali agqwala, okwenza kube ukukhetha okudumile ezikhungweni zokucubungula amakhemikhali nokuhlanza amanzi. I-PVC ilula, ingabizi kakhulu, futhi ayiphenduli kumakhemikhali amaningi anamandla, nakuba imikhawulo yokushisa nokucindezela kufanele iqashelwe. Kumakhemikhali agxile kakhulu noma ashisayo, amavalvu ensimbi noma anengqimba angase afaneleke kakhulu.

I-Carrie Foundation (Beijing) Valve Manufacturing CO., LTD. ingumkhiqizi oqinisekisiwe we-ISO okhiqiza ama-ball valve ahlangabezana nezindinganiso ze-API, ANSI, ne-DIN esebenzisa izinto zokusebenza ezisezingeni eliphezulu nokuhlolwa okuqinile. Inkampani inikezela ngamanani ancintisanayo, ukulethwa okusheshayo, nokusekelwa okuhle kwe-after-sales ezimbonini ezifana ne-oyela negesi, amakhemikhali, nokwelashwa kwamanzi. Ithimba labo lobunjiniyela liphinde linikeze izixazululo ezenziwe ngokwezifiso, ukuze uthole i-valve efaniswa ngqo nohlelo lwakho.

Isici se-double block & bleed sivumela i-valve ukuthi ihlukanise i-process media kanyekanye kusukela kuzo zombili izingxenye zepayipi elingaphezulu naphansi, kuyilapho ikhipha noma yimuphi umfutho obhajwe endaweni ye-valve. Lokhu kunikeza ukuphepha okwengeziwe kubasebenzi abanakekela futhi kuvimbela ukungcola lapho besebenza ezinhlelweni ezinomfutho. Isici esifiseleka kakhulu ekusetshenzisweni kwezinto eziyingozi eziketshezini noma egesini, futhi sivame ukunikezwa kuma-ball valve agibele ku-trunnion.

Qala ngokunquma ububanzi bepayipi, izinga lokugeleza elidingekayo, ingcindezi yokusebenza kanye nezinga lokushisa, kanye nohlobo lwamakhemikhali ezinto ozisebenzisayo. Bese uhlonza ukuthi umsebenzi uwukuvula noma ukuvala nje okulula noma udinga ukulawula ukugeleza, okuzokuqondisa ekukhetheni idizayini ejwayelekile, enesiqu esikhuphukayo, noma i-V-port. Ukubonisana nomkhiqizi oqeqeshiwe njenge-Carrie Foundation kuqinisekisa ukuthi imininingwane yakho ye-valve iyahambisana namazinga asebenzayo nezimo zokusebenza.

Ama-valve e-ball asezimbonini atholakala eneziphetho ezinemicu (threaded ends) emisebeni emincane noma enengcindezi ephansi, iziphetho ezinamafulethi (flanged ends) kububanzi obukhulu nengcindezi ephezulu, kanye neziphetho ezishiselwe (welded ends) ukuze kufakwe okungaphumeli (leak-free) unomphela. Ukuxhumana ngemicu kunikeza ukufakwa okulula, imiklamo enamafulethi ivumela ukususwa kalula ukuze kulungiswe, futhi amajoyinti ashiselwe anikeza ukuqina okuphelele emsebenzini obalulekile wamapayipi. Ukukhetha kuncike ohlelweni lwakho lwamapayipi, izidingo zokulungisa, kanye nezidingo zengcindezi yokusebenza.
