Ngokuhlalutya umgaqo wesakhiwo sevalve yebhola yombhobho esisigxina, ufumene ukuba umgaqo wokutywinwa uyafana, usebenzisa umgaqo "wepiston effect", kwaye kuphela isakhiwo sokutywinwa esahlukileyo.
I-Valve ekusebenziseni ingxaki ibonakaliswe ngokukodwa kwiidigri ezahlukeneyo, iindlela ezahlukeneyo zokuvuza, ngokomgaqo wokutywinwa kwesakhiwo kunye nofakelo kunye nohlalutyo lomgangatho wokwakha, izizathu zokuvuza kwevalve yile miba ilandelayo.
1. Ufakelo lweValve kunye nomgangatho wokwakha sesona sizathu siphambili
Kulwakhiwo lofakelo aluyi ngqalelo kwindawo yokutywina i-valve kunye nokutywinwa kokukhusela i-ring ring, ukutywinwa komonakalo womphezulu;Ufakelo lugqityiwe, umbhobho wokuvuthela kunye nokuvuthela kwevalvu akugqitywanga, akucocekanga, xa kusebenza kukho i-slag ye-welding okanye igrabile exinge phakathi kwebhola kunye neringi yesitulo sokutywina, okubangele ukusilela kokutywinwa.Kule meko, kwimeko engxamisekileyo, indawo yokutywina ephezulu kufuneka ifakwe okwethutyana kunye nenani elifanelekileyo le-sealant yokunciphisa ukuvuza, kodwa ayikwazi ukuyicombulula ngokupheleleyo ingxaki, ukuba kuyimfuneko, indawo yokutywinwa kwevalve kunye nokutywinwa kwesitulo sokutywina kufuneka kuthathelwe indawo.
2. I-valve mechanical processing, izinto zokutywina, kunye nezizathu zomgangatho wendibano
Nangona ulwakhiwo lwevalve lulula, luyimfuno ephezulu yeemveliso zomgangatho wokulungiswa koomatshini, umgangatho wayo wokulungisa uchaphazela ngokuthe ngqo ukusebenza kokutywinwa.Umsesane wokutywina wesihlalo kunye nococeko lwendibano yesitulo kunye nommandla ngamnye womphezulu weringi kufuneka ubalwe ngokuchanekileyo, uburhabaxa bomphezulu bufaneleke.Ukongeza, ukukhethwa kwezinto ezithambileyo zokutywina kubaluleke kakhulu, kungekuphela nje ukuqwalasela ukubola kunye nokumelana nokunxiba kodwa nokuqwalasela ukuqina kunye nokuqina kwayo.Ukuba ithambile kakhulu, iya kuchaphazela ukukwazi ukuzicoca;ukuba inzima kakhulu, kuya kuba lula ukuphuka.
3. Ukukhetha okunengqiqo ngokwesicelo kunye neemeko zokusebenza
Ukusebenza kokutywinwa okuhlukeneyo kunye nezakhiwo zokutywinwa kwevalve usebenzisa amaxesha ahlukeneyo, kuphela ngamaxesha ahlukeneyo ukukhetha i-valve eyahlukileyo, ukufumana umphumo ofanelekileyo wesicelo.Kwimeko yombhobho werhasi okwiNtshona-Mpuma, umzekelo, iivalvu zebhola yombhobho esisigxina enetywina ephindwe kabini kufuneka ikhethwe kangangoko (ngaphandle kweevalvu zebhola ezijikelezayo ezitywinwe ngokunyanzeliswayo, ezixabisa kakhulu).Ngale ndlela, ukuba itywina elinyukayo liyonakele, itywina elisezantsi lisengasebenza.Ivalve yebhola evalwe ngenkani kufuneka ikhethwe ukuba kufuneka ukuthembeka ngokupheleleyo.
4. Kuba iivalvu ezinolungelelwaniso lokutywinwa olwahlukeneyo, iindlela ezahlukeneyo zokusebenza, ukugcinwa, kunye nokusevisa kufuneka kusetyenziswe.
Kwiivalvu ezingenayo ukuvuza, ivalve inokuzaliswa ngegrisi ngaphambi nasemva komsebenzi ngamnye okanye rhoqo kwiinyanga ezi-6 ngexabiso elincinci kwi-stem kunye ne-sealant injection port, kwaye kuphela kwiimeko apho ukuvuza kwenzeke okanye kungenakutywinwa ngokupheleleyo. isixa esifanelekileyo se-sealant esitofelweyo.Ngenxa ye-viscosity ephezulu ye-sealant, ukuba i-valve ayidlanga ngokuzaliswa nge-sealant, iya kuchaphazela umphumo wokuzicoca we-spherical surface, ehlala iphikisana, ukuzisa i-grit encinci kunye nolunye ukungcola phakathi kwetywina ukubangela ukuvuza.Kwiivalve ezinezitywina ezimbini, ukuba iimeko zokhuseleko lwesiza zivumela, uxinzelelo kwi-valve cavity kufuneka lukhutshwe kwi-zero, ukuqinisekisa ukutywinwa.
