Mhangura alloy kupfeka kuramba, yakakodzera tembiricha T ≤ 200 ℃, nominal pressure PN ≤ 1.6MPa mvura uye chiutsi, chinowanzoshandiswa mumagedhi mavharuvhu, globe mavharuvhu, cheki mavharuvhu, plug mavharuvhu, nezvimwe.
7, chrome simbi isina tsvina
Chrome Stainless simbi inowanzoshandiswa mhando 2Cr13, 3Cr13 mushure mekudzima uye kudziya kurapwa, yakanaka corrosion resistance. Inowanzo shandiswa tembiricha t ≤ 450 ℃, zita rekumanikidza PN ≤ 32MPa mvura, chiutsi nemafuta uye mamwe mavharuvhu enhau.
8, chromium nickel titanium simbi isina tsvina
Iyo inowanzoshandiswa mhando yechromium nickel simbi isina simbi ndeye 1Cr18Ni9ti, ine yakanaka yekudzivirira ngura, inodzivirira kukukurwa uye kupisa kupisa. Inokodzera tembiricha T ≤ 600 ℃, zita rekumanikidza PN ≤ 6.4MPa chiutsi, nitric acid uye mamwe midhiya, inoshandiswa kune globe valve, bhora vharafu, nezvimwe.
9, nitriding simbi
Iyo yakajairwa giredhi yenitriding simbi ndeye 38CrMoAlA, ine yakanaka yekurasa kuramba uye abrasion kuramba mushure mekuviga carburizing. Inowanzo shandiswa kumagetsi echiteshi chegedhi mavharuvhu ane tembiricha T ≤ 540 ℃ uye nezita rekumanikidza PN ≤ 10MPa.
10, kubhowekana
Boronizing nemuviri kana disc body material yakanyatsogadziriswa chisimbiso pamusoro, boronizing pamusoro kurapwa, chisimbiso pamusoro kupfeka kuramba zvakanaka chaizvo. Inoshandiswa kune simba chirimwa blowdown valve.
Gasi gedhi vharuvhu Yemaoko Shandura vhiri reruoko neruoko kuti dzinde risimuke nekudonha, kuitira kutyaira ndiro yegedhi kumusoro nekudzika kuvhura nekuvhara vharafu. Iyo vharafu INOPINGWA NE "VAKAZARA" UYE "VHARA" INORATIDZA MACHANISM, TENDENZA WACHI, gedhi rinodonha, chinongedzo chinonongedza PASI "KUSVIRA", uye vharafu AKAVHWA. Tendeuka COUNTERCOCKWISE, GATE RINOSIMUKA, NTSONO inonongedza PASI “PA” PASI, UYE VAVIRI INOZUKA. Paunenge uchiyedza kudzvanywa kwepombi, zvinodikanwa kushandisa yakawedzera tsvimbo handwheel. Vhara vharafu uye inofanira kuvhara panzvimbo (ona chinongedzo chinzvimbo). Shandura vhiri reruoko kuti uvhare, woritendeudzira neruchibhino kuti rivhure.
