Kuiswa uye disassembly yemavharuvhuziva kuruboshwe nekurudyi - shinda dzeruoko
Kupisa kwekushanda kwevhavha kunotaridzirwa nezvinhu izvo valve inogadzirwa. Tembiricha yezvakajairika valve zvinhu ndeiyi inotevera:
The valve
Kushandiswa kwekushisa
Grey iron valve
-15 ~ 250 ℃
Inogoneka yakakandwa simbi vharuvhu
-15 ~ 250 ℃
Ductile iron valve
-30 ~ 350 ℃
High nickel cast iron valve
Iyo yakanyanya tembiricha yekushanda i400 ℃
Carbon steel valve
-29 ~ 450 ℃, t1Cr5Mo, alloy simbi vharafu
Iyo yakanyanya tembiricha yekushandisa i550 ℃
12Cr1MoVA, alloy simbi vharafu
Iyo yakanyanya kupisa tembiricha i570 ℃
1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti mavharuvhu esimbi isina tsvina
-196 ~ 600 ℃
Copper alloy valve
-273 ~ 250 ℃
Plastic valve (Naironi)
Maximum inoshanda tembiricha 100 ℃

-180 ~ 150 ℃
Plastic valve (natural rubber diaphragm valve)
Maximum inoshanda tembiricha 60 ℃
Plastic valve (NBR, NEoprene diaphragm valve)
Maximum inoshanda tembiricha 80 ℃
Plastic valve (fluorine rubber diaphragm valve)
Maximum inoshanda tembiricha 200 ℃
Kana rabha nepurasitiki zvichishandiswa kugadzira vharafu, kupisa kwerabha nepurasitiki kuchakunda.
Ceramic valve, nekuda kwekushomeka kwayo kwekushisa kwekudzivirira, inowanzoshandiswa mumamiriro ekushanda pasi pe150 ℃. Munguva ichangopfuura, imwe super performance ceramic valve yabuda, inogona kumira tembiricha iri pasi pe1000 ℃.
Girazi valve. Kusapisa tembiricha kuramba, kunowanzo shandiswa kune ekushanda mamiriro ari pasi pe90 ℃.
Enamel valve, tembiricha yekushanda inogumira neiyo yekuisa chisimbiso, iyo yakanyanya tembiricha yekushanda haipfuure 150 ℃.
Vhuru muviri zvinhu zvinonyanya kusanganisira: C kabhoni simbi, I 1Cr5Mo chromium-molybdenum simbi, H Cr13 akatevedzana Stainless simbi, K malleable cast iron, L aruminiyamu alloy, P 0Cr18Ni9 akatevedzana Stainless simbi, PL 00Cr19Ni10 akatevedzana Stainless simbi, Q nodular simbi. 0Cr12Ni12Mo2 series simbi isina tsvina, RL 00Cr17Ni14Mo2 series simbi isina tsvina, S mapurasitiki, T mhangura nemhangura alloy, Ti titanium uye titanium alloy, V chromium molybdenum vanadium simbi, Z grey cast iron.
Gungano revhavha uye disassembly zivisa shinda yekuruboshwe nekurudyi
Kunyatso ziva kana shinda iri kuruboshwe kana kurudyi ndiyo yakanyanya ruzivo rwevharuvhu kusangana uye disassembly. Saka unoona sei kana shinda iri kuruboshwe kana kurudyi?
Inogona kutsanangurwa nemukati kana kunze shinda pane valve. Muzhinji, iwo ndeaya akanaka uye akaipa ekugadzira shinda kudzivirira kusunungura shinda. Zvakaita sedzinde, stem nut shinda yekubatanidza: mhete yakasimba padzinde nati yasara kutenderera, shinda pagumbo reruoko ndeyekutenderera kwerudyi, shinda yetrapezoidal pa stem nut yasara kutenderera. Pamusoro pazvo, Engle inosimuka yeshinda iri kuruboshwe rweshinda inonzi ruboshwe; Zvikasadaro, iri dextral rotation.
