Ubushushu obuphantsi beSango iValve
Iimpawu zoYilo lweeMveliso
Iziphelo ezijiyileyo zisetyenziselwa ukusika okanye ukudibanisa umbhobho weendaba phantsi koxinzelelo lwegama phakathi kwe-PN1.6-42.0MPa (Cass150 ~ 2500) amaqondo obushushu asebenzayo ≤ 600in kwishishini le-oyile kushishino lwemichiza yezityalo zamandla efosili.
Iimpawu eziphambili zesakhiwo ziquka:
1.Zombini uyilo kunye nokuveliswa zenziwa ngokungqongqo ngokulandela i-GB/T12234AP600kunye ne-AP1602.Iimveliso zibonisa isakhiwo esifanelekileyo.itywina elithembekileyo, ukusebenza kakuhle kunye nemodeli entle.
I-2.Co i-hard alloy welded welded surface, enxibe i-resistant proof proof, i-abrasion proof kunye nexesha elide.
3.Umphezulu kunye nemidiya yokulungelelanisa yeshafu yevalve ifakwe initrogen ukuze ikwazi ukumelana nokhukuliseko kunye nokugruzuka.
I-4.PN≥15.0MPa(I-Class900), umgodi ophakathi usebenzisa isakhiwo sokutywina esiziqinisayo ukuze umsebenzi wokutywina uqiniswe kunye nokunyuka koxinzelelo ukuze kuqinisekiswe ukusebenza kokutywinwa.
5.Akukho sakhiwo sokutywinwa ngasemva kwivalve, ngoko ke i-id yokutywina inokuthenjwa
6.Izinto eziphathekayo zokuzaliswa kunye nobukhulu be-flange zinokukhethwa kwaye zihambelane ngokuhambelana nezicelo kunye neemfuno zokusetyenziswa.Oko kunokwanelisa zonke iintlobo zeemfuno zokusebenza.
