Yintoni oFumana Uyazi malunga neeVave zeBhola

Enye yeevalvu ezisetyenziswa kakhulu kwimizi-mveliso, iivalvu zebhola zihlala zisetyenziswa xa kucinywa ukuvalwa.Ivalve yebhola yafumana igama layo kwindawo enomngxuma-ngaphandle wesphere evumela ukudlula kwimidiya xa ivula okanye iyibhlokile xa ivaliwe.Lawa ngamalungu osapho lwekota yeevalvu zoshishino.

Ivalve yebhola isoloko isetyenziswa kumashishini amaninzi ngoko ke akumangalisi ukufumanisa ukuba imfuno yayo iphezulu.Kule mihla, ungafumana umgangatho ophezulu owenziwe eTshayina iivalvu zebhola okanye iivalvu zebhola ezenziwe eIndiya.

Iimpawu zeValve yeBhola eqhelekileyo

Iintlobo ezininzi zevalve yebhola zabelana ngeempawu ezifanayo nezichazwe ngezantsi:
# Ukujonga i-Swing-oku kuthintela ukubuya ngasemva kwemidiya
# Ukuma kweValve- oku kuvumela kuphela ukujika kwe-90-degree
# I-Anti-static - oku kuthintela ukwakhiwa kombane ongatshintshiyo onokubangela iintlantsi
# Ukhuseleko lomlilo-isihlalo sentsimbi yesibini sakhiwe ukuba sisebenze njengezihlalo ezongezelelweyo kwizicelo zobushushu obuphezulu.

Izinto eziluncedo kunye nezingeloncedo kwiValve yeBhola

Iivalve zebhola zilungile ukuba zisetyenziswe xa inkqubo idinga ukuvulwa nokuvala ngokukhawuleza.Ezi zikwaluncedo kwizicelo apho kufuneka itywina eliqinileyo ngaphandle kokuqwalasela uxinzelelo oluphezulu lwangaphakathi.
Nangona kunjalo, iivalve zebhola zinamandla alinganiselweyo okuginya.Enyanisweni, ezi azikhuthazwa ukuba zilawule ukuhamba kweendaba.Iivalvu zebhola zinezihlalo ezivezwe ngokuyinxenye, ezinokuthi ziguguleke ngokukhawuleza xa kusetyenziswa udaka.Ezi kwakhona kunzima ukuvula ngokukhawuleza kwaye ngesandla xa uxinzelelo luphezulu.

Izixhobo eziqhelekileyo zeValve yeBhola

Iivalvu zebhola ziza kwizinto ezahlukeneyo.Ngokuxhomekeke kubume besicelo, iivalve zebhola zihlala zenziwe okanye zenziwe ngentsimbi, insimbi engenasici, kunye nezinye i-alloys zensimbi.Izihlalo zevalve yebhola zingenziwa ngemathiriyeli ye-elastomeric efana ne-PTFE okanye isinyithi, ehlala intsimbi engatyiwa.

Iinxalenye zeValve yeBhola

Nangona kukho iindidi ezininzi zevalve yebhola, kukho amacandelo amahlanu aqhelekileyo akhoyo kuzo zonke iivalvu zebhola njengoko kubonwa kulo mzobo ungezantsi:

# Umzimba
Umzimba ugcina onke amalungu kunye
# Isitulo
Isihlalo sivala ivalve ngexesha lokuvalwa
# Ibhola
Ibhola ivumela okanye ivalele indlela yemidiya.
# Umqalisi
I-actuator okanye i-lever ihambisa ibhola ukuze ivule okanye ivale.
# Isiqu
Isiqu sidibanisa inqanaba nebhola.

Iizibuko zeValve yeBhola

Ngokuqhelekileyo, iivalve zebhola zinamazibuko amabini.Kodwa ngokufika kweenkonzo ezintsha, iivalve zebhola zinokufikelela kumazibuko amane.Ezi zidla ngokuphawulwa njengeendlela ezimbini, iivalvu zebhola ezinendlela-ntathu okanye ezine.Ivalve yeendlela ezintathu ingaba ne-L-configuration okanye i-T-configuration.

Ball Valve Working Mechanism

I-disc yebhola ivuliwe okanye ivaliwe ngokuguqula i-actuator ikota yekota okanye i-90-degrees.Xa i-lever ihambelana nokuhamba kwemidiya, i-valve ivumela ukuba i-valve idlule.Xa i-lever iba yi-perpendicular ekuhambeni kwemidiya, i-valve ivimbela ukuhamba kokugqibela.

Izahlulo zeValve yeBhola

Iivalvu zebhola zihlelwa ngeendlela ezininzi.Ungadibana namaqela evalve ngokusekwe kwinani lamacandelo okanye uhlobo lweevalvu zebhola.

Ngokusekelwe kwiZindlu

Ungahlela iivalvu zebhola ngokuxhomekeke kwinani lamalungu emizimba yazo.Eyona nto inexabiso eliphantsi phakathi kwezintathu, ivalve yebhola enye yenziwe ngebhloko enye eyenziwe ngesinyithi.Oku akunako ukuchithwa ukucoca okanye ukulungiswa.Iivalve zebhola enye zifanelekile kwizicelo zoxinzelelo oluphantsi.

Ngakolunye uhlangothi, i-valve yebhola ephindwe kabini yenziwe ngamaqhekeza amabini adityaniswe yimicu.Olu hlobo kufuneka lususwe ngokupheleleyo kumbhobho ngelixa licocwa okanye litshintshwe.Okokugqibela, amacandelo evalve yebhola enamacandelo amathathu aqhagamshelwe ngeebholiti.Ugcino lunokwenziwa kwivalvu nokuba isancanyathiselwe kumbhobho.

Ngokusekwe kuYilo lweDiskhi

Uyilo lwebhola luhlelo olukhulu lweevalvu zebhola.Iqanjwe ngokufanelekileyo ngenxa yokuba ibhola ixhonywe phezulu kwesikhondo, ivalve yebhola edadayo lolona yilo luqhelekileyo kolu didi.Xa ivala, ibhola isiya ngakwindawo evulekileyo yomlambo.Umthwalo woxinzelelo unceda ukutywina i-valve ngokuqinileyo.

Kwelinye icala, uyilo lwebhola olunyuswe kwi-trunnion lubanjwa ngokuthe gqolo ziitrunnions ezibekwe emazantsi ebhola.Esona sicelo sifanelekileyo kwiivalve zebhola ezifakwe kwi-trunnion zezo zinezivulo ezinkulu kunye nemigangatho yoxinzelelo oluphezulu, ngokuqhelekileyo ngaphezu kwe-30 bar.

Ngokusekwe kwiDayimitha yoMbhobho

Iivalve zebhola nazo zinokuhlelwa ngokusekelwe kubungakanani boqhagamshelwano ngokumalunga nobubanzi bemibhobho.Ivalve yebhola encitshisiweyo ithetha ukuba i-diameter yevalve yisayizi enye encinci kunolo lwemibhobho.Oku kubangela ilahleko yoxinzelelo oluncinci.Iivalvu zebhola enye zihlala zinohlobo lokunciphisa.

Iindidi zodidi olupheleleyo zinobubanzi obufanayo naleyo yemibhobho.Iingenelo zolu hlobo zibandakanya akukho lahleko loxinzelelo kunye nokucoca lula.Iintlobo ezigcweleyo zibiza kakhulu ngenxa yobukhulu bevalve.Okokugqibela, Uhlobo lwe-V lunomngxuma omilise u-V owenza kube lula ukulawula ulwelo nanini na xa ivalve ivuliwe.

Izicelo zeValve yebhola

Iivalvu zebhola zihlala zifumaneka kwiintlobo ngeentlobo zezicelo.Amaxesha amaninzi, ubuya kubafumana kwiinkqubo eziqukuqelayo kwiinqanawa, iinkonzo ezonakalisayo kunye neenkonzo zokhuseleko lomlilo.Ezi azisetyenziswa kwizicelo apho ungcoliseko kungumba ofana nalawo akwiinkonzo zokulungisa ukutya.Iivalve zebhola kunzima ukuzicoca.

Isishwankathelo

Iivalvu zebhola ziyakhula kunye namashishini anxulunyaniswa nawo.Ukuba ngabathengi, ukuzifundisa malunga nokuba yeyiphi ivalve yebhola ebalulekileyo.
