Buka Isithombe Esikhulu
Ama-valve ebhola angenye yezinhlobo zama-valve ezisetshenziswa kakhulu ezimbonini ezahlukene.Isidingo se-valve yebhola sisakhula.Wake wazibuza ukuthi ama-valve ebhola enza kanjani umthelela ezinhlelweni zakho zokusebenza.Kulesi sihloko, uzofunda mayelana nezingxenye ezivamile ze-valve yebhola kanye nemisebenzi yazo.Ngaphezu kwalokho, sizokukhombisa ukuthi i-valve yebhola isebenza kanjani ukukusiza ukuthi uyiqonde kangcono ngaphambi kokuba ube neyohlelo lwakho lokusebenza.
Iyini i-Ball Valve?
Njengoba igama layo liphakamisa, i-valve yebhola ine-disc efana nebhola esebenza njengesithiyo lapho i-valve ivaliwe.Izinkampani ezikhiqiza ama-valve ebhola zivame ukuklama i-valve yebhola ukuthi ibe i-quarter-turn valve kodwa futhi ingaba uhlobo olujikelezayo lapho ilawula noma iphambukisa ukuhamba kwemidiya.
Ama-valve ebhola avame ukusetshenziswa ezinhlelweni ezidinga ukuvalwa okuqinile.Zaziwa ngokuthi zinengcindezi ephansi.Ukujika kwayo okungu-90-degree kwenza kube lula ukusebenza noma ngabe imidiya inevolumu ephezulu, ingcindezi noma izinga lokushisa.Bayonga kakhulu ngenxa yempilo yabo ende yokusebenza.
Ama-valve amabhola alungele amagesi noma uketshezi olunezinhlayiya ezincane.Lawa ma-valve awasebenzi kahle kuma-slurries njengoba lawa ewalimaza kalula izihlalo ezithambile ze-elastomeric.Ngenkathi benamandla okudonsa, ama-valve ebhola awasetshenziswa kanjalo ngoba ukungqubuzana okuvela ku-throttling kungalimaza nezihlalo kalula.
Izingxenye ze-Ball Valve
Kunezinhlobonhlobo eziningi zama-valve ebhola, njenge-valve yebhola lezindlela ezi-3 nama-valve ebhola ezintweni ezahlukene.Eqinisweni, indlela yokusebenza ye-valve yendlela engu-3 nayo ihlukile kune-valve yebhola evamile.Kunezindlela eziningi zokuhlukanisa ama-valve.Kungakhathaliseki ukuthi yikuphi, kunezingxenye ze-valve eziyisikhombisa ezivamile kuwo wonke ama-valve.
Umzimba
Umzimba uwuhlaka lwe-valve yonke yebhola.Isebenza njengesithiyo kumthwalo wengcindezi evela kwabezindaba ngakho-ke akukho ukudluliselwa kokucindezela kumapayipi.Ibamba zonke izingxenye ndawonye.Umzimba uxhunywe kumapayipi ngamajoyinti anentambo, abhawudiwe noma ashiselwe.Ama-valve ebhola angahlukaniswa ngokuya ngohlobo lomzimba, ovame ukuphonswa noma owenziwe ngomgunyathi.

Isiqu
Ukuvulwa noma ukuvala i-valve kunikezwa isiqu.Yilokhu futhi okuxhumanisa i-ball disc nelever, isibambo noma i-actuator.Isiqu yisona esizungezisa idiski lebhola ukuze lilivule noma livale.
Ukupakisha
Lona i-gasket esiza ukuvala ibhonethi nesiqu.Izinkinga eziningi zenzeka kule ndawo ngakho ukufaka kahle kubalulekile.Ukuxega kakhulu, ukuvuza kwenzeka.Iqine kakhulu, ukunyakaza kwesiqu kukhawulelwe.
Ibhonethi
Ibhonethi iyisembozo sokuvuleka kwevalvu.Lokhu kusebenza njengesithiyo sesibili sokucindezela.Ibhonethi iyona ebamba zonke izingxenye zangaphakathi ndawonye ngemva kokuba lezi zifakwe ngaphakathi emzimbeni wevalvu.Ivamise ukwakhiwa ngempahla efanayo nomzimba we-valve, ibhonethi ingafojwa noma iphonswe.
Ibhola
Lona i-disc ye-valve yebhola.Ukuba umngcele wesithathu obaluleke kakhulu wokucindezela, ukucindezela kwabezindaba kusebenza ngokumelene ne-disc uma isendaweni evaliwe.Amadiski ebhola avame ukwenziwa ngensimbi engumgunyathi noma nganoma iyiphi impahla ehlala isikhathi eside.Idiski yebhola ingamiswa njengalapho kunevalvu yebhola elintantayo, noma ingafakwa njengaleyo yevalve yebhola efakwe ku-trunnion.
Isihlalo
Ngezinye izikhathi kuthiwa amasongo ophawu, yilapho i-disc yebhola iphumula khona.Kuye ngokuthi i-disc yebhola yakhiwe kanjani, isihlalo sinamathiselwe noma cha ebholeni.
I-Actuator
Ama-Actuator angamadivayisi adala ukuzungezisa okudingekayo yi-valve yebhola ukuze uvule i-disc.Ngokuvamile, lezi zinomthombo wamandla.Amanye ama-actuator angalawulwa ukude ukuze ama-valve asasebenza ngisho noma atholakala ezindaweni ezikude noma okunzima ukufinyelela kuzo.
Ama-Actuator angeza njengamasondo esandla kumavalvu ebhola asebenza mathupha.Ezinye izinhlobo zama-actuator zihlanganisa izinhlobo ze-solenoid, izinhlobo ze-pneumatic, izinhlobo ze-hydraulic, namagiya.
Isebenza Kanjani Ivalve Yebhola?
Ngokuvamile, indlela yokusebenza kwe-valve yebhola isebenza ngale ndlela.Kungakhathaliseki ukuthi isetshenziswa ngesandla noma i-actuator, amandla athile ahambisa i-lever noma isibambo ekujikeni kwekota ukuze uvule i-valve.Lawa mandla adluliselwa esiqwini, anyakaze i-disc ukuze ivuleke.
I-ball disc iyaphenduka futhi uhlangothi lwalo olunegodi lubheke ukuhamba kwemidiya.Kuleli qophelo, i-lever isendaweni ye-perpendicular futhi ichweba lihambisana ngokuhlobene nokugeleza kwemidiya.Kukhona indawo yokumisa isibambo eduze koxhumano phakathi kwesiqu nebhonethi ukuvumela ukujika kwekota kuphela.
Ukuvala i-valve, i-lever ibuyela emuva ngekota.Isiqu siyanyakaza ukuze siphendulele idiski yebhola kwelinye icala, sivimbe ukugeleza kwemidiya.I-lever isendaweni efanayo futhi imbobo, i-perpendicular.
Nokho, qaphela ukuthi kunezinhlobo ezintathu ze-ball disc movement.Ngayinye yalezi inemisebenzi ehlukene yokusebenza.
I-valve yebhola elintantayo ine-disc yayo yebhola elenga esiqwini.Akukho ukusekela engxenyeni engezansi yebhola ngakho-ke i-disc yebhola incike kancane ekucindezelekeni kwangaphakathi kwama-valve ebhola elicinene aziwa ngalo.
Njengoba i-valve ivala, ingcindezi yomugqa okhuphukayo ovela kwabezindaba iphusha ibhola libheke esihlalweni esifakwe ngezansi somfula.Lokhu kunikeza ukuqina kwe-valve enhle, okwengeza kusici sayo sokuvala.Isihlalo esingezansi somklamo we-valve yebhola elintantayo sithwala umthwalo wokucindezela kwangaphakathi lapho i-valve ivaliwe.
Olunye uhlobo lomklamo we-ball disc ivalvu yebhola efakwe nge-trunnion.Lokhu kunesethi yama-trunnions ezansi kwediski yebhola, okwenza idiski yebhola ime.Lawa ma-trunnions aphinde amunca amandla asuka emthwalweni wokucindezela lapho i-valve ivala ukuze kube nokungqubuzana okuncane phakathi kwe-ball disc kanye nesihlalo.Ingcindezi yokuvala yenziwa kuzo zombili izimbobo ezikhuphuka nomfula.
Lapho i-valve ivala, izihlalo ezigcwele intwasahlobo zihamba ngokumelene nebhola elizungeza kuphela eksisi yalo.Lezi ziphethu ziphusha isihlalo siqinise ebholeni.Izinhlobo zamabhola agibele i-Trunnion zilungele izinhlelo zokusebenza ezingadingi ukucindezela okuphezulu ukuhambisa ibhola esihlalweni esingezansi komfula.
Okokugcina, i-valve yebhola ye-stem ekhuphukayo isebenzisa indlela yokutshekisa nokujika.I-ball disc ijikela esihlalweni lapho i-valve ivala.Uma ivuleka, idiski iyatsheka ukuze izisuse esihlalweni futhi ivumele ukugeleza kwemidiya.
