Ngaba uyasokola ukukhetha ivalve efanelekileyo yeprojekthi yakho?Ngaba ukhathazwa luluhlu olubanzi lweemodeli zevalvu kunye neempawu kwimarike?Kuzo zonke iintlobo zeeprojekthi zobunjineli, ukukhetha ivalve efanelekileyo kubaluleke kakhulu.Kodwa imarike igcwele iivalve.Ngoko sihlanganise isikhokelo sokukunceda ngokulula nangobulumkokhetha imveliso yevalvu elungileyo kuwe.Nokuba ufuna ulawulo lokuhamba, ulawulo loxinzelelo okanye ukunqunyulwa kwamanzi, sineengcebiso kunye namaqhinga akho.Thatha inyathelo lokuzithemba ngale maze yesivalo kwaye wonwabele iindleko kunye nokonga ixesha ngelixa usebenza kwiprojekthi yobunjineli esebenzayo.

1.Chonga injongo yesivalo kwisixhobo okanye isixhobo

Misela iimeko zokusebenza zevalve: ubunjani bendawo esebenzayo, uxinzelelo olusebenzayo, ukushisa okusebenzayo kunye nemodi yokulawula.

2.Khetha uhlobo lwevalvu echanekileyo

Ukhetho oluchanekileyo lohlobo lwevalvu lusekwe kwingqinisiso epheleleyo yomyili wayo yonke inkqubo yokuvelisa kunye neemeko zokusebenza njengemfuneko, ekukhetheni uhlobo lwevalvu, umyili kufuneka abe nobuchule kuqala kwiimpawu zesakhiwo kunye nokusebenza kwevalve nganye.

3.Qinisekisa uqhagamshelo lwesiphelo sevalve

Kuqhagamshelo oludityanisiweyo, udibaniso lweflange, kunye noqhagamshelo oludityanisiweyo, ezokuqala zimbini zisetyenziswa ngokuqhelekileyo.Iivalve ezinemisonto ubukhulu becala zine-diameter engaphantsi kwe-50mm, ukuba ubungakanani bedayamitha bukhulu kakhulu, ukufakela kunye nokutywinwa kwenxalenye yokudibanisa kunzima kakhulu.I-valve edibeneyo ye-Flange, ukufakwa kwayo kunye nokuchithwa kwayo kukulungele ngakumbi, kodwa i-valve edibeneyo edibeneyo ininzi kakhulu, ixabiso liphezulu, ngoko lifanelekile kwiindidi ezahlukeneyo kunye noxinzelelo loxhumo lombhobho.Uxhumo oludibeneyo lufanelekile kwiimeko eziphezulu zokusika umthwalo kwaye zithembeke ngakumbi kunoxhumo lwe-flange.Nangona kunjalo, ukuchithwa kunye nokufakwa kwakhona kweevalve ezidibeneyo kunzima kakhulu, ngoko ke ukusetyenziswa kwayo kunqunyelwe kwizihlandlo apho ngokuqhelekileyo kunokusebenza ngokuthembekileyo ixesha elide, okanye apho iimeko zokusetyenziswa zikrola kwaye ubushushu buphezulu.

4.Ukukhethwa kwezinto zeValve

Ukukhethwa kweqokobhe levalvu, amalungu angaphakathi kunye nemathiriyeli yokutywina yangaphezulu, ukongeza ekuthatheni ingqalelo iimpawu ezibonakalayo zesixhobo sokusebenza (ubushushu, uxinzelelo) kunye neempawu zekhemikhali (umhlwa), kufuneka zilawule ukucoceka kwendawo ephakathi (akukho masuntswana aqinileyo. ), ukongeza, kodwa kubhekiselelwe kwizibonelelo ezifanelekileyo zikarhulumente kunye nokusetyenziswa kwesebe.Ukhetho oluchanekileyo nolufanelekileyo lwezixhobo zevalve lunokufumana ubomi benkonzo yezoqoqosho kunye nokusebenza kakuhle kwevalve.Ukulandelelana okukhethiweyo kwezixhobo zomzimba we-valve yile: isinyithi esityhidiweyo - i-carbon steel - insimbi engenasici, kunye nokukhethwa kokulandelelana kwezinto zokutywina izinto zokutywina: irabha - ithusi - i-alloy steel -F4.

5.okunye

Ukongezelela, izinga lokuhamba kunye nenqanaba loxinzelelo lwe-fluid ehamba nge-valve kufuneka lunqunywe, kwaye i-valve efanelekileyo kufuneka ikhethwe ngokusebenzisa ulwazi olukhoyo (njengekhathalogu yemveliso ye-valve, iisampuli zemveliso ye-valve, njl.). 

 JinbinValvengumenzi ozibophelele ekuboneleleni ngezivalo ezikumgangatho ophezulu, kwaye iimveliso zayo zithunyelwa kumazwe amaninzi akuMzantsi-mpuma weAsia naseMelika.Qhagamshelana nathi ngoku kwaye usivumele senze esona sisombululo sevalvu silungele wena!
