Kupisa kwekushanda kwevhavha

Kupisa kwekushanda kwevhavha kunotarirwa nezvinhu zvevhavha.Kupisa kwezvinhu zvinowanzoshandiswa zvevhavha ndezvizvi:
 
Kupisa kwekushanda kwevhavha
 
Gray cast iron valve: -15～250℃
 
Inogoneka yakakandwa simbi vharafu: -15～250℃
 
Ductile iron valve: -30 ~350℃
 
High nickel cast iron valve: yakanyanya kupisa tembiricha ndeye 400 ℃
 
Carbon simbi vharafu: -29～450℃, inokurudzirwa tembiricha t <425 ℃ mu JB/T3595-93 chiyero
 
1Cr5Mo, alloy simbi vharafu: yakanyanya kushanda tembiricha iri 550 ℃
 
12Cr1MoVA, alloy simbi vharafu: yakanyanya kushanda tembiricha iri 570 ℃
 
1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti simbi isina tsvina valve: -196～600℃
 
Copper alloy valve: -273～250℃
 
Plastic valve (nylon): tembiricha yepamusoro yekushanda i100 ℃
 
Plastiki vharafu (chlorinated polyether): yakanyanya kushanda tembiricha 100 ℃
 
Plastiki vharafu (polyvinyl chloride): yakanyanya kushanda tembiricha 60 ℃
 
Plastic valve (polytrifluorochlorethylene): -60 ~120 ℃
 
Plastic valve (PTFE): -180～150℃
 
Plastic valve (natural rubber diaphragm valve): Yakanyanya kushanda tembiricha 60 ℃
 
Plastic vharafu (nitrile rabha, neoprene diaphragm vharafu): yakanyanya tembiricha yekushanda i80 ℃
 
Plastic valve (fluorine rabha diaphragm vharafu): yakanyanya tembiricha yekushanda i200 ℃
 
Kana rabha kana mapurasitiki achishandiswa kugadzira vharafu, kupisa kwerabha nepurasitiki ndiko kuchatonga
 
Mavharuvhu eCeramic, nekuda kwekushomeka kwawo kwekushisa, anowanzo kushandiswa mumamiriro ekushanda ari pasi pe150 ° C.Munguva ichangopfuura, vharuvhu yekeramic inoshanda zvikuru yakaonekwa, inogona kumira kutonhora kwakanyanya pasi pe1000 ° C.
 
Mavharuvhu egirazi haana kusimba tembiricha uye anowanzo shandiswa mumamiriro ekushanda ari pasi pe90°C.
 
Kupisa kwekushisa kwevhavha yeenamel kunogumira nezvinhu zvemhete yekuisa chisimbiso, uye kupisa kwakanyanya kwekushanda hakupfuuri 150 ° C.
 
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, QNi 02C iron2 akatevedzana. simbi isina tsvina, RL 00Cr17Ni14Mo2 series Stainless steel, S plastic, T copper and copper alloy, Ti titanium uye titanium alloy, V chromium molybdenum vanadium simbi, Z grey cast iron.
