Iivalvu zidlala indima ebalulekileyo ekulawuleni ukuhamba kolwelo kunye neegesi kwiinkqubo ezahlukeneyo zamashishini.Ukuqinisekisa ukusebenza ngokugqibeleleyo kunye nokhuseleko, kubalulekile ukuqonda imveliso yevalvu kunye nefuthe layo ekusebenzeni kakuhle kwenkqubo kunye nokusebenza kakuhle.Kule bhlog, siza kuphonononga yonke into ekufuneka uyazi malunga neziphumo zevalvu.
Yintoni imveliso yevalvu?
Imveliso yevalve ngumthamo wolwelo onokuthi ivalve ilawule okanye ilawule njengoko idlula kwinkqubo.Esi siphumo silinganiswa kwiiyunithi ezahlukeneyo ngokuxhomekeke kwisicelo.
Imveliso yevalve idla ngokuhlelwa ngobukhulu bayo, imilo kunye nezinto zokwakha.Ivalve enkulu inomthamo ophezulu wokukhupha kunevalve encinci, oku kuthetha ukuba inokulawula umthamo omkhulu wolwelo okanye igesi.
Ukongeza kubungakanani, uhlobo lwevalve lukwachaphazela amandla ayo okuphuma.Ezinye iivalve zenzelwe ukujongana neentlobo ezithile zolwelo okanye iigesi, okuthetha ukuba zinokulungiswa kusetyenziso oluthile.
Ukuqonda ukuhamba kweValve
Ukuhamba kwevalve ngomnye umba obalulekileyo wokuphuma kwevalvu.Xa ivalve ivuliwe, ivumela ulwelo okanye igesi ukuba idlule kwaye ingene kwinkqubo.Umthamo wolwelo okanye irhasi edlula kwivalvu ibizwa ngokuba yi-flow.
Ukuhamba kwevalve kunokuba ne-laminar okanye i-turbulent.Ukuhamba kwe-Laminar kubonakaliswe ngokunyakaza okugudileyo, okuzinzileyo, ngelixa i-turbulent flow ibonakaliswe ngokukhawuleza, intshukumo yesiphithiphithi.
Kwiimeko ezininzi, ukuhamba kwe-laminar kukhethwa ngaphezu kokuhamba kwesiphithiphithi kuba kuqikelelwa ngakumbi kwaye kulula ukulawula.Nangona kunjalo, ezinye izicelo zifuna ukuhamba kwesiphithiphithi, njengaxa ulwelo okanye iigesi kufuneka zixutywe okanye ziphazamiseke.
Izinto ezichaphazela iSiphumo seValve
Izinto ezininzi zinokuchaphazela ukukhutshwa kwevalve.Ezi ziquka:
1. Uxinzelelo: Iinkqubo zoxinzelelo oluphezulu zifuna iivalve ezinokusingatha imithwalo eyongeziweyo.
2. Iqondo lobushushu: Olunye ulwelo kunye neegesi ziyabuva ubushushu, kwaye iivalvu kufuneka ziyilelwe ukuba zimelane namaqondo obushushu agqithisileyo.
3. I-Viscosity: I-Viscous okanye i-viscous fluids ifuna i-valve enokusingatha ukwanda kokumelana kunye noxinzelelo.
4. Uhlobo lolwelo okanye igesi: Olunye ulwelo kunye neegesi zineempawu ezizodwa zeekhemikhali ezinokuchaphazela ukusebenza kwevalvu.
Ngokuqonda ezi zinto, unokukhetha i-valve eya kubonelela ngokusebenza kakuhle, ubomi benkonzo kunye nokhuseleko.
Ukuququmbela
Imveliso yeValve yinto ebalulekileyo ekusebenzeni kwenkqubo yezoshishino kunye nokhuseleko.Xa ukhetha i-valve kwisicelo sakho, izinto ezifana nobukhulu, uhlobo, ukuhamba, uxinzelelo, ubushushu kunye ne-viscosity kufuneka ziqwalaselwe ukuqinisekisa ukusebenza kakuhle kunye nokhuseleko.
Uxhobe ngolu lwazi, unokukhetha ivalve ehlangabezana neemfuno zakho ezizodwa kwaye ibonelele ngokuthembekileyo, ukusebenza okuhlala ixesha elide.
