Ukushisa okusebenzayo kwevalve kuchongwa yimpahla yevalve.Ubushushu bezinto ezisetyenziswa ngokuqhelekileyo kwiivalvu zezi zilandelayo:
Ubushushu bokusebenza kwevalve
Ivalve yentsimbi engwevu: -15～250℃
Ivalve yentsimbi ethambileyo: -15～250℃
Ivalve yentsimbi yentsimbi: -30～350℃
Ivalve yentsimbi yenickel ephezulu: ubushushu obuphezulu bokusebenza yi-400 ℃
Ivalve yentsimbi yeCarbon: -29～450℃, ubushushu obucetyiswayo t<425℃ kwi-JB/T3595-93 standard
I-1Cr5Mo, i-valve yentsimbi ye-alloy: ubushushu obuphezulu bokusebenza yi-550 ℃
I-12Cr1MoVA, ivalve yentsimbi yealloyi: elona qondo lobushushu liphezulu lisebenza ngama-570 ℃
I-1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti ivelufa yentsimbi: -196～600℃
Ivalve yengxubevange yobhedu: -273～250℃
Ivalve yePlastiki (inayiloni): obona bushushu bokusebenza buphezulu yi-100℃
Ivalve yePlastiki (i-polyether ene-chlorinated): ubushushu obuphezulu bokusebenza 100℃
Ivalve yeplastiki (i-polyvinyl chloride): ubushushu obuphezulu bokusebenza 60℃
Ivalve yePlastiki (polytrifluorochlorethylene): -60～120℃
Ivalve yePlastiki (PTFE): -180～150℃
Ivalve yePlastiki (ivalve yerabha yendalo ye-diaphragm): Ubushushu obuninzi bokusebenza buyi-60℃
Ivalve yeplastiki (irabha ye-nitrile, ivalve ye-neoprene diaphragm): ubushushu obuphezulu bokusebenza yi-80 ℃
Ivalve yePlastiki (ivalve yerabha ye-fluorine diaphragm): elona qondo lobushushu liphezulu lokusebenza yi-200 ℃
Xa irabha okanye iplastiki isetyenziselwa ukufakwa kwevalvu, ukuxhathisa kobushushu berabha kunye neplastiki kuya kulawula
Iivalvu zeCeramic, ngenxa yokunganyangeki kwamaqondo obushushu, zidla ngokusetyenziswa kwiimeko zokusebenza ezingaphantsi kwe-150°C.Kutshanje, ivalve ye-ceramic esebenza kakhulu ivele, enokumelana namaqondo obushushu angaphantsi kwe-1000 ° C.
Iivalvu zeglasi azikwazi ukumelana nobushushu kwaye zidla ngokusetyenziswa kwiimeko zokusebenza ezingaphantsi kwama-90°C.
Ukumelana nokushisa kwe-valve ye-enamel kunqunyelwe yizinto zendandatho yokutywina, kwaye ubushushu obuphezulu bokusebenza akudluli i-150 ° C.
izixhobo Valve umzimba ikakhulu ziquka: C carbon steel, I 1Cr5Mo chromium molybdenum intsimbi, H Cr13 series steel stainless, K malleable cast intsimbi, L aluminiyam ingxubevange, P 0Cr18Ni9 series steel stainless, PL 00Cr19Ni10 series steel stainless, QNi 02C iron2 series, QNi2C ductile iron2 steel stainless, RL 00Cr17Ni14Mo2 series steel stainless, S iplastiki, T yobhedu kunye nengxubevange yobhedu, Titanium Titanium kunye nengxubevange titanium, V chromium molybdenum vanadium intsimbi, Z grey cast iron.
