Amanqaku aphambili okukhetha iivalvu—iTWS Valve

1. Cacisa injongoivalvukwisixhobo okanye kwisixhobo

Misela iimeko zokusebenza zevalvu: uhlobo lwesixhobo esifanelekileyo, uxinzelelo lokusebenza, ubushushu bokusebenza kunye nendlela yokulawula.

2. Khetha uhlobo lwevalvu ngokuchanekileyo

Ukukhetha uhlobo lwevalvu ngokuchanekileyo kuyimfuneko ukuze umyili ayiqonde ngokupheleleyo yonke inkqubo yemveliso kunye neemeko zokusebenza. Xa ekhetha uhlobo lwevalvu, umyili kufuneka aqale aqonde iimpawu zesakhiwo kunye nokusebenza kwevalvu nganye.

3. Chonga uqhagamshelo olupheleleyo lwevalvu

Phakathi koqhagamshelo olunemisonto, uqhagamshelo lweflange, kunye noqhagamshelo olunemiphetho edibeneyo, ezimbini zokuqala zezona zisetyenziswa kakhulu. Iivalvu ezinemisonto ikakhulu ziivalvu ezinobubanzi obungaphantsi kwe-50mm. Ukuba ububanzi bukhulu kakhulu, ukufakelwa kunye nokutywinwa kwenxalenye edibanisayo kuya kuba nzima kakhulu. Iivalvu ezinemisonto kulula kakhulu ukuzifaka nokuziqhekeza, kodwa zinzima kwaye zibiza kakhulu kuneevalvu ezinemisonto, ngoko ke zifanelekile kuqhagamshelo lwemibhobho yobubanzi obahlukeneyo kunye noxinzelelo. Uqhagamshelo oludibeneyo lufanelekile kwimithwalo enzima kwaye luthembekile ngakumbi kuqhagamshelo olunemisonto. Nangona kunjalo, kunzima ukuqhawula nokufaka kwakhona ivalvu eqhagamshelwe ngokuhlanganisa, ngoko ke ukusetyenziswa kwayo kunqunyelwe kwiimeko apho idla ngokusebenza ngokuthembekileyo ixesha elide, okanye apho iimeko zokusetyenziswa zinzima kwaye ubushushu buphezulu.

4. Ukukhethwa kwezinto zevalvu

Xa ukhetha izinto zegobolondo yevalvu, iindawo zangaphakathi kunye nomphezulu wokutywina, ukongeza ekuqwalaseleni iimpawu zomzimba (ubushushu, uxinzelelo) kunye neempawu zeekhemikhali (ukubola) zesixhobo sokusebenza, ukucoceka kwesixhobo (esineziqwenga eziqinileyo okanye ezingenazo) kufuneka kuqondwe. Ukongeza, kuyimfuneko ukubhekisa kwimigaqo efanelekileyo karhulumente kunye nesebe lomsebenzisi. Ukukhetha ngokuchanekileyo nangokufanelekileyo kwezinto zevalvu kunokufumana ubomi benkonzo obunoqoqosho kunye nokusebenza okungcono kwevalvu. Ulandelelwano lokukhetha izinto zomzimba wevalvu lu: isinyithi esityhidiweyo-intsimbi yekhabhoni-intsimbi engatyiwayo, kwaye ulandelelwano lokukhetha izinto zeringi yokutywina lu: irabha-ubhedu-intsimbi ye-alloy-F4.

5. Okunye

Ukongeza, izinga lokuhamba kunye nenqanaba loxinzelelo lolwelo oluhamba ngevalvu nalo kufuneka lichongwe, kwaye ivalvu efanelekileyo kufuneka ikhethwe kusetyenziswa idatha ekhoyo (efanaiikhathalogu zemveliso yevalvu, iisampulu zemveliso yevalvu, njl.njl.).
