Ivalve ihlala ineengxaki ezinzima ngexesha lenkqubo yokusetyenziswa, njengevalve ayivalwanga ngokuqinileyo okanye ngokuqinileyo. Ndingenza ntoni?
Kwiimeko eziqhelekileyo, ukuba ayivalwanga ngokuqinileyo, qinisekisa kuqala ukuba i-valve ivaliwe kwindawo. Ukuba ivalwe endaweni, kusekho ukuvuza kwaye ayikwazi ukutywinwa, ke jonga indawo yokutywina. Ezinye iivalvu zinezitywina ezishenxisekayo, ngoko zikhuphe kwaye uzisile uze uzame kwakhona. Ukuba ayikavalwa ngokuqinileyo, kufuneka ibuyiselwe kwifektri ukuze ilungiswe okanye ifakwe endaweni yevalve, ukuze ingachaphazeli ukusetyenziswa okuqhelekileyo kwevalve kunye nokuvela kweengxaki ezifana neengozi zemeko yokusebenza.
Ukuba i-valve ayivalwanga ngokuqinileyo, kufuneka uqale ufumane apho ingxaki ikhona, kwaye uyisombulule ngokwendlela ehambelana nayo.
Izizathu zokuba kutheni ivalve ingavalwanga ngokuqinileyo ngokuqhelekileyo ngolu hlobo lulandelayo:
(1) Kukho izinto ezingacocekanga ezincanyatheliswe kumphezulu wokutywina, kwaye ukungcola kufakwe emazantsi evalve okanye phakathi kwesivalo sevalve kunye nesitulo sevalve;
(2) Umsonto wesikhondo wevalve unomhlwa kwaye ivalve ayinakuguqulwa;
(3) Umphezulu wokutywina wevalve wonakalisiwe, nto leyo ebangela ukuvuza okuphakathi;
(4) Isiqu sevalve kunye nevalve clack aziqhagamshelwanga kakuhle, ukwenzela ukuba ivalve isikhewu kunye nesitulo sevalve singakwazi ukudibana.
Indlela yonyango yevalve ayivalwanga ngokuqinileyo:
1. Ukungcola okuncanyathiselwe kumphezulu wokutywina wevalve
Ngamanye amaxesha i-valve ayivalwanga ngokukhawuleza. Kungenzeka ukuba kukho ukungacoceki okubambekayo phakathi komphezulu wokutywina wevalve. Ngeli xesha, musa ukusebenzisa amandla ukuvala ivalve. Kufuneka uvule ivalve kancinane, uze uzame ukuyivala. Zama kwakhona kwaye kwakhona. Ngokuqhelekileyo, inokupheliswa. Jonga kwakhona. Umgangatho wamajelo eendaba nawo kufuneka ugcinwe ucocekile.
Okwesibini, umsonto wesiqu uyarusa
Kwiivalvu ezihlala zikwimeko evulekileyo, xa zivalwe ngengozi, ngenxa yokuba imicu ye-valve stem igqwalile, ayinakuvala ngokuqinileyo. Kule meko, i-valve inokuvulwa kwaye ivalwe ngamaxesha amaninzi, kwaye i-bottom of the valve body inokubetha ngesando esincinci ngexesha elifanayo, kwaye i-valve inokuvalwa ngokuqinileyo ngaphandle kokugaya kunye nokulungiswa kwevalve.
Okwesithathu, umphezulu wokutywina wevalve wonakalisiwe
Kwimeko yokuba utshintshi aluvalwanga ngokuqinileyo emva kokuzama amaxesha amaninzi, oko kukuthi, indawo yokutywina yonakaliswe, okanye indawo yokutywina yonakaliswe yi-corrosion okanye i-particle scratches phakathi. Kule meko, kufuneka kuxelwe ukulungiswa.
Okwesine, isiqu sevalve kunye nevalve clack azidityaniswanga kakuhle
Kule meko, kuyimfuneko ukongeza ioli yokuthambisa kwi-valve stem kunye ne-valve stem nut ukuqinisekisa ukuvuleka okuguquguqukayo kunye nokuvalwa kwevalve. Kufuneka kubekho isicwangciso sokulungisa esisesikweni ukomeleza ukugcinwa kwesivalo.
