Ivalve yeBhola vs.

Jonga umfanekiso oMkhulu
Zininzi iivalvu zoshishino ezikhoyo kwimarike.Iindidi ezahlukeneyo zevalve yeshishini zisebenza ngokwahlukileyo.Abanye balawula ukuhamba kwamajelo eendaba ngelixa abanye bewahlulahlula amajelo eendaba.Abanye balawula ulwalathiso lwamajelo eendaba.Ezi zikwahluka ngoyilo kunye nobukhulu.

Iivalve ezimbini eziqhelekileyo ezisetyenziswa kwimizi-mveliso ziivalve zebhola kunye neengcango zesango.Zombini ziyaziwa ngokubonelela ngeendlela eziqinileyo zokuvala.Eli nqaku liza kuthelekisa iivalvu ezimbini kwizinto ezahlukeneyo ezifana neendlela zokusebenza, uyilo, amazibuko, kunye nezinto ezithandwayo.

Yintoni iValve yeBhola?

Ivalve yebhola yinxalenye yosapho lwevalve yekota.Ithatha kuphela i-90-degree turning ukuba ivule okanye ivale.Uyilo lwevalve yebhola inebhola enomngxuma esebenza njengediski evumela ukuhamba kwemidiya.Ubukhulu becala kwizicelo ezingezizo eziludaka, iivalvu zebhola zikwafanelekile kwizicelo ezifuna ukuvalwa okuqinileyo.

Ukuvulwa ngokukhawuleza kunye nokuvalwa kwebhola kwenza ukuba kubaluleke kwezinye izicelo ezifuna ukuhlukaniswa kwemidiya.Iivalvu zebhola ziqhele ukusetyenziswa kwizicelo zoxinzelelo oluphantsi.Ngamafutshane, iivalve zebhola zilungele ulawulo kunye nolawulo lwemidiya kunye nokuhla koxinzelelo oluncinci.

Yintoni iValufa yeSango?

Kwelinye icala, iivalvu zesango zezosapho lwevalve yentshukumo.Kungenjalo kwaziwa ngokuba ivelufa yemela okanye ivelufa yesilayidi, ivelufa yesango inediski ecaba okanye yewedge esebenza njengesango.Eli sango okanye idiski ilawula ukuhamba kolwelo ngaphakathi kwevalve.I-valve yesango isetyenziswe kakuhle xa ukuhamba komgca weendaba kunye nokuhla kwengcinezelo encinci kukhethwa.

Yivalve evaliweyo ene-throttling umthamo.Yenzelwe ngakumbi ukuhamba kwempahla njengolawulo lokuhamba.Ifaneleke ngakumbi kumajelo osasazo atyebileyo, idiskhi ecaba yeevalvu zesango yenza kube lula ukunqumla uhlobo lwemidiya olunjalo.

Ivalve yesango nayo iyinxalenye yosapho olujikelezayo njengoko ivili okanye i-actuator ifuna ukujikeleziswa ukuze i-wedge okanye idiski ivuleke.Kwindawo yalo yokuvala, isango lihamba lisiya phantsi naphakathi kwezihlalo ezibini ezibekwe kwindawo ephezulu yediski kunye nasezantsi njengoko kubonisiwe kumfanekiso ongentla.

Isebenza Njani Ivalve yeBhola?

Iivalvu zebhola zinengqukuva evulekileyo evumela ukudlula kwimidiya.Ukuba ujonga kwi-cross-section ye-valve yebhola engezantsi, ukusebenza kukujikeleza kwe-shaft okanye isiqu ngekota yokujika.Isiqu si-perpendicular kwindawo yebhola yevalve.

Ulwelo luvumelekile ukuba ludlule xa isiqu sikwi-engile elungileyo ngokumalunga nediski yebhola.Ukunyakaza kwecala leendaba kudlala indima ebalulekileyo kwindlela yokuvala.Iivalvu zebhola zisebenzisa uxinzelelo lolwelo ukusebenza phezu kwevalve okanye isihlalo ukunika itywina eliqinileyo, kuxhomekeke kubume bevalve yebhola.

Iivalve zebhola zinokuba lizibuko elipheleleyo okanye lincitshiswe izibuko.Ivalve yebhola egcweleyo ithetha ukuba ububanzi bayo buyafana nombhobho.Oku kuvumela i-torque ephantsi yokusebenza kunye nokuhla koxinzelelo.Nangona kunjalo, kukho kwakhona uhlobo oluncitshisiweyo lwezibuko apho ubungakanani bevalve bubukhulu obuncinci kunobukhulu bombhobho.

Isebenza Njani Ivalufa yeSango?

Iivalve zesango zisebenza ngokuphakamisa isango okanye idiski ukuvumela imidiya ukuba idlule kwivalve.Ezi ntlobo zeevalvu zivumela kuphela ukuhamba kwe-unidirectional kunye nokuhla koxinzelelo oluncinci.Ubuya kubona iivalvu zesango ezinamavili ezandla.I-handwheel ifakwe kwi-packing.

Kukho iindidi ezimbini zoyilo lwesikhondo sevalve yesango.Xa eli vili lesandla lijikeleza, isiqu sikhuphukela kwindawo yangaphandle kwaye, ngexesha elifanayo, siphakamisa isango.Olunye uhlobo lwevalve yesango yivalve yesango engaphumiyo.Oku kubonakaliswe ngesiqu esifakwe kwi-wedge, ngaloo ndlela sityhila kumajelo eendaba.

Xa ivalve yesango ivula, indlela iba nkulu.Umzila wokuhamba awukho umgca ngengqiqo yokuba amajelo angakwazi ukuthatha i-void njengoko kuboniswe kumfanekiso ongezantsi.Ukuba ivalve yesango isetyenziswe njenge-throttle, iya kuba nesantya esingalinganiyo sokuhamba.Oku kuya kubangela ukungcangcazela.Ukungcangcazela okunjalo kunokubangela umonakalo kwidiski.

I-valve Flow Direction

Iivalvu zebhola kunye neevalvu zesango, ngokwesiqhelo, zi-bi-directional.Oku kuthetha ukuba iivalvu zebhola zinamandla okuthintela imidiya ukusuka ekupheleni komsinga kunye nesiphelo esisezantsi.Jonga lo mfanekiso ungezantsi.

iValve Seal Umthamo

Kwiivalvu zebhola, izitywina zinokumiselwa kuyilo lwevalve yebhola edadayo kwaye inokudada kwivalve yebhola efakwe kwi-trunnion.Ekubeni iivalve zebhola zihlala zisetyenziswa kwizicelo zoxinzelelo oluphantsi, ngokuqwalasela ubume bendlela yokusebenza kwayo, amatywina aphambili ahlala enziwe nge-PTFE kunye nezinye izinto ezinxulumeneyo.

Nangona ukuvala ngokukhawuleza kunye nokuvulwa kwevalve yebhola kunokuba luncedo, oku kunokubangela iingxaki ezithile.Iivalvu zebhola ziqhelene nehamile yamanzi okanye ukunyuka koxinzelelo ngequbuliso xa kuvalwe ivalve.Le meko iyonakalisa izihlalo zevalve yebhola.

Ngaphezu koko, ihamile yamanzi inokunyusa uxinzelelo ngaphakathi kwevalve yebhola.Kwizicelo apho iimeko ezinjalo zinokuthi zenzeke, oko kukuthi izinto ezinokutsha, kukho isitywina sesihlalo esingxamisekileyo, esihlala senziwe ngentsimbi.Lo ngumqobo wesibini kwiimeko apho isitywina se-elastomeric sonakaliswa kwiinkonzo zoxinzelelo oluphezulu.Ukunciphisa uxinzelelo, iivalve zebhola zinokuba ne-pressure vent efakwe.

Iivalvu zesango zinciphisa ukuhla koxinzelelo xa zivulwe ngokupheleleyo.Oku kungokusetyenziswa koyilo lwezibuko lokuzala.Oku kuthetha ukuba ubungakanani bevalve bulingana nobukhulu bombhobho.Kungenxa yolu phawu lweevalvu zesango ezibanika inzuzo ngaphezu kweevalve zebhola.Ukubethelwa kwamanzi akwenzeki kwiivalvu zesango.

Icala elisezantsi levalve yesango kukuba, ukuhluka koxinzelelo oluphezulu kwenzeka rhoqo xa kuvaliwe.Ukungqubana kunokubangela ukuba isihlalo kunye nediski ziguge.

Uyilo lweValve kunye noMahluko woKwakha

Umahluko ophambili phakathi kweevalve zebhola kunye neevalve zesango yisakhiwo sazo nokuba zisebenza ngokufanayo.

Kwiivalvu zebhola, ukuhamba kwemidiya kukhululekile.Ngaphandle koku, idizayini yevalve yebhola ivumela ukuba ihlale ixesha elide nasemva kokusetyenziswa kakhulu.Kakade ke, ubani ufanele acingele uhlobo lwemathiriyeli esetyenziswayo ukuyivelisa.

Ngelixa iivalvu zebhola zingaboneleli ngolawulo olululo, ukuvaleka kwazo okuqinileyo sesinye sezona zilungileyo kusetyenziso loxinzelelo oluphantsi.Iivalvu zebhola zithembekile kulo mba.Ilahleko yoxinzelelo oluphantsi yenye umgangatho weevalvu zebhola.Nangona kunjalo, ngenxa yokukwazi ukujika kwekota yeevalvu zebhola, kuthatha indawo eninzi.

Ivalve yesango, kwelinye icala, isebenzisa ivili lesandla ukuvula okanye ukuvala idiski.Umzimba wevalve nawo ubhityile ngakumbi, ngenxa yoko, kufuneka indawo emxinwa kuphela.Ngokwahlukileyo kwiivalvu zebhola, iivalve zesango, zibonelela ngolawulo olusulungekileyo njengoko lunamandla okuginya.Isenokungabi nokuvalwa ngokukhawuleza kunye nobuchule, kodwa inokulawula kungekuphela nje ukuhamba kweendaba kodwa kunye noxinzelelo lwayo.
