Uthotho lwe-DBB2: IiBhloko ezimbini zeBolted Double kunye neeValve zeBleed
Iikhathalogu
Iivalvu zeHikelok-Block kunye neBleed
IntshayeleloIndibaniselwano eyahlukileyo yeHikelok yeebloko ezimbini kunye neenkqubo zeevalvu ezivuzayo zivumela utshintsho olugudileyo ukusuka kwinkqubo yeepayipi zenkqubo ukuya kwizixhobo, zibonelela ngamanqaku ambalwa okuvuza, ubunzima obuphantsi obufakiweyo, kunye nesithuba esincinci. Iivalvu zeBlock kunye neBleed zenzelwe iindawo zokwahlukanisa iipayipi zenkqubo, ukuxhonywa ngqo kwizixhobo, ukudibana okusondeleyo kwezixhobo, ukwahlukanisa iibloko ezimbini kunye nokopha, imingxunya kunye nemijelo yamanzi.
IimbonakaloUxinzelelo oluphezulu lokusebenza ukuya kuthi ga kwi-10000 psig (689 bar)Ubushushu obusebenzayo ukusuka kwi -10 ℉ ukuya kwi 1200 ℉ (-23 ℃ ukuya kwi 649 ℃)Ukudibanisa uluhlu olukhoyo lweqhekeza elinye, ulwakhiwo lwebholti yeflange ukuya kwiflange ye-DBB luyafumaneka ngobukhulu ukusuka kwi-1/2 ukuya kwi-2Yenzelwe ngokwe-ASME VIII kunye ne-ANSI B16.34Ubunzima, indawo kunye nokonga iindleko ngaphezu koyilo lwendabukoUkulandeleka ngokupheleleyo kwezinto
IingeneloUbunzima, indawo kunye nokonga iindleko ngaphezu koyilo lwendabukoI-stem seal elayishwe bukhoma iqinisekisa ukutywinwa okuhle kuluhlu loxinzelelo kunye nobushushu. I-stem edibeneyo ngaphakathi ikhusela ekuqhumeni.Uyilo oluchasene ne-staticIziqinisekiso zeekhemikhali nezinto ezibonakalayo ziyafumanekaIzihlalo ezithwele izixhobo eziphilayo zigcina inkqubo ivaliwe xa kusenzeka utshintsho kuxinzelelo kunye nobushushuUkunciphisa uxinzelelo lwe-cavity kuthintela ukunyanzeliswa okugqithisileyo kokwanda kobushushu be-system media xa ivalvu ivaliweUkunciphisa ukukhutshwa komoya ongcolileyo
Ezinye iindlelaIzinto ezikhethiweyo: intsimbi engatyiwayo engama-316, intsimbi yekhabhoni, i-Alloy 20, i-Alloy 400, i-Incoloy 825, kunye nezinto zentsimbi engatyiwayo ezimbiniUthotho oluKhethekileyo oluBophayo, uthotho oluBophayo oluNciphisiweyoUkhetho lwenkonzo yegesi emuncu
