ISikhululo saMandla soMbane esiPhezulu seGlobhe iValve
Iimpawu zoYilo lweeMveliso
Ivalve yeglowubhu isetyenziselwa ukusika okanye ukudibanisa umbhobho weendaba phantsi koxinzelelo lwegama phakathi kwePN1.6-160MPa (Class150-2500) iqondo lokushisa elisebenzayo600C.kwishishini le-oyile kushishino lweekhemikhali kurhwebo lwesichumisi kunye noshishino lwamandla.
Iimpawu eziphambili zesakhiwo ziquka:
1. Rational structure.reliable ukutywina ukusebenza okugqwesileyo imbonakalo entle
2. Co-radix ingxubevange welded ukutywina umphezulu anti-ukunxiba ukhukuliseko-ubungqina abrasion-ubungqina kunye nokusebenzisa ubomi obude.
3. Umphezulu kunye nemidiya yokulungelelanisa ye-valve shaft ifakwe initrogen ukuze ibe nokhukuliseko kunye nokumelana nokukrala.
4. PN>25.0MPa(Class1500) .umngxuma ophakathi sebenzisa 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.
