Uvuthondaba lwesakhiwo sevalve yenaliti – okudityanisiweyo okudityanisiweyo kwesiqu se-NV1 inaliti yenaliti

Njengevalve yenaliti ebanzi,Ivalve yenaliti ye-NV1iye yaba yeyona isetyenziswa kakhuluivalve yenalitichwetheza kwiHikelok. Ngoko kutheni le ntoivalve yenalitiebizwa ngokuba yi comprehensiveivalve yenaliti, kwaye zithini izizathu zokuba ibe yeyona isetyenziswa kakhuluivalve yenaliti?

Okokuqala, ngu-ivalve yenalitiyenziwe ngokupheleleyo. Kuthetha ukuthini' ngokupheleleyo? Ukubeka ngokulula, kuthetha ukudibanisa umzimba wevalvu kunye nebhonethi ibenye. IIvalve yenaliti ye-NV1Iphulukene nebhonethi kwaye nebhonethi yenzelwe kumzimba wevalvu. I-forging iyonke inamandla aphezulu xa kuthelekiswa noqhagamshelo oluthungelweyo lwantlandlolo, ngenxa yokungabikho kwamanqaku anokuthi avuze kuqhagamshelo phakathi komzimba wevalve kunye nebhonethi.

Okulandelayo sisikhondo sevalve enamacandelo amabini. I-valve ebizwa ngokuba yi-stem ye-valve-piece-piece yahlula i-valve stem ibe ngamacandelo amabini, kunye neziqu ze-valve eziphezulu kunye nezantsi zixhunywe ngeehenjisi. Isiqu sevalve sokuqala kufuneka siqhutywe kwaye sitywinwe, kwaye izikhondo zevalve ephezulu nasezantsi zahlula ukutywinwa kunye nokuhanjiswa. Kukho iinzuzo ezintathu eziqhelekileyo:

1. Isiqu sevalve ephezulu siqhuba kunye nezitywina zesikhondo sevalve esezantsi, ukwahlula ukungcoliseka komsonto wothumelo lokuthambisa igrisi phakathi, kwaye nokuthintela igrisi yokuthambisa ukuba ingakhukuliswa liphakathi ukuthambisa ixesha elide.

2. Isiqu sevalve esezantsi sitshintshile ukusuka kwintshukumo yokuqala ejiyileyo ukuya phezulu ukuya ezantsi ukuya phezulu nasezantsi, nto leyo evumelana kakhulu nokupakishwa kwaye inobomi obude benkonzo.

3. Uqhagamshelwano lokutywina lwencam yevalvu lutshintsha ngokuthe ngqo ukusuka ekujikelezeni nasekucinezeleni ukuya phezulu nasezantsi kwintshukumo. Uqhagamshelwano olungajikeleziyo lunokuphucula kakhulu ubomi benkonzo yencam yevalve kunye nesitulo, okwenza ukuba ibe yomelele kwaye ithembekile.

Ke izikhondo ezibini zevalve zenziwe zizonke, kwaye ngokudibanisa umzimba wevalve kunye nevalve cap, amandla ayaphuculwa kwaye indawo evuzayo enokubakho iyancitshiswa. Iimeko zokutywinwa kweziqu zevalve ephezulu kunye nesezantsi ziphuculwe kakhulu xa kuthelekiswa nesiqu sevalve yokuqala, nokuba kukupakishwa okanye incam yevalve kunye nokutywinwa kwesitulo, ukuze isetyenziswe ngokubanzi.
