I-High Voltage Electric Power Station Globe Valve
Izici Zokuklama Imikhiqizo
Ivalvu yeglobhu isetshenziselwa ukusika noma ukuxhuma imidiya yepayipi ngaphansi kwengcindezi encane phakathi kwePN1.6-160MPa(Class150-2500) okushisa okusebenzayoss600C.embonini kawoyela embonini yamakhemikhali ekhemisi umanyolo kanye nemboni yamandla.
Izici eziyinhloko zesakhiwo zihlanganisa:
1. Isakhiwo esinengqondo.ukubeka uphawu okuthembekile ukusebenza okuhle kakhulu ukubukeka okuhle
2. I-co-radix alloy welded sealing surface anti-ukugqoka-ukuguguleka-ubufakazi bokuthi imihuzuko nokuphila isikhathi eside.
3. Ingaphezulu kanye nemidiya yokulungisa ye-valve shaft ifakwe i-nitrogen ukuze ingaguguleki futhi imelane.
4. PN>25.0MPa(Class1500).isikhala esimaphakathi sisebenzisa isakhiwo sokuvala esiziqinisayo ukuze umsebenzi wokuvala uqiniswe
kanye nokukhuphuka kwengcindezi ukuze kuqinisekiswe ukusebenza kokuvala.
5. Asikho isakhiwo sokuvala esibuyela emuva ku-valve, ngakho-ke i-id yokuvala ithembekile.
6. Impahla yokugcwalisa kanye nosayizi we-flange ingakhethwa futhi ifaniswe ngokuya ngezicelo kanye nezidingo zokusetshenziswa.Lokho kungenelisa zonke izinhlobo zezidingo zokusebenza.
