✧ Iimpawu zeValve yeSango leBonnet eliSekiweyo ngoxinzelelo
Uxinzelelo oluphezulu kunye nokuguquguquka kobushushu obuphezulu
- Izinto zevalvu kunye noyilo lwesakhiwo ziqwalaselwe ngokukodwa ukuze zilungelelanise iimeko zokusebenza phantsi koxinzelelo oluphezulu kunye nobushushu obuphezulu.
- Ingasebenza ngokuzinzileyo phantsi kwamanqanaba aphezulu oxinzelelo afana neKlasi 900LB, 1500LB, kunye ne-2500LB.
Ukusebenza kakuhle kokutywina
- Ulwakhiwo lwesivalo sokutywina uxinzelelo luqinisekisa ukuba ivalvu isenokuhlala ikwimeko eqinileyo yokutywina phantsi koxinzelelo oluphezulu.
- Uyilo lomphezulu wokutywina ngentsimbi luphucula ngakumbi ukusebenza kokutywina kwevalvu.
Ukuthembeka koqhagamshelo lokuphela kwe-butt welding
- Indlela yokudibanisa i-butt welding iyasetyenziswa ukwenza isakhiwo esiqinileyo esidibeneyo phakathi kwevalvu kunye nenkqubo yepayipi.
- Le ndlela yoqhagamshelo inciphisa umngcipheko wokuvuza kwaye iphucula amandla kunye nozinzo lwenkqubo iyonke.
Ukugqwala kunye nokumelana nokuguguleka
- Ivalvu yenziwe ngezinto ezimelana nokugqwala nezingagugiyo ngaphakathi nangaphandle ukuphucula ubomi benkonzo kunye nokuthembeka kwevalvu.
Isakhiwo esincinci kunye nokugcinwa okulula
- Ivalvu incinci kwaye ithatha indawo encinci, elungele ukufakwa nokugcinwa kwindawo encinci.
- Uyilo lwesitywino kulula ukuluhlola nokulutshintsha, nto leyo enciphisa iindleko zokulungisa kunye nexesha.
