Ukufakwa kanye nokuqaqaama-valvekhomba izintambo zesobunxele nesokudla
Ukushisa okusebenzayo kwe-valve kunqunywa into eyenziwa yi-valve. Izinga lokushisa lezinto ezivamile ze-valve limi kanje:
I-valve
Ukusetshenziswa kwezinga lokushisa
I-valve yensimbi empunga
- 15 ~ 250 ℃
I-valve yensimbi ethambile ethambile
- 15 ~ 250 ℃
I-valve yensimbi ye-ductile
- 30 ~ 350 ℃
I-valve yensimbi ye-nickel ephezulu
Izinga lokushisa eliphezulu lokusebenza ngu-400 ℃
I-Carbon steel valve
-29 ~ 450℃, tI-1Cr5Mo, i-valve yensimbi ye-alloy
Izinga lokushisa eliphezulu lokusebenza ngu-550 ℃
I-12Cr1MoVA, i-valve yensimbi ye-alloy
Izinga lokushisa eliphakeme kakhulu lokusebenza ngu-570 ℃
1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti amavalvu ensimbi engagqwali
- 196 ~ 600 ℃
I-valve ye-alloy yethusi
- 273 ~ 250 ℃
Ivalvu yepulasitiki (Inayiloni)
Izinga lokushisa eliphezulu lokusebenza ngu-100 ℃
I-valve yepulasitiki (i-polyether eyi-chlorinated)
Izinga lokushisa eliphezulu lokusebenza ngu-100 ℃
I-valve yepulasitiki (PVC)
Izinga lokushisa eliphezulu lokusebenza ngu-60℃
I-valve yepulasitiki (i-polytrifluorovinyl chloride)
- 60 ~ 120 ℃
Ivalvu yepulasitiki (PTFE)
- 180 ~ 150 ℃
I-valve yepulasitiki (i-valve yenjoloba yemvelo ye-diaphragm)
Izinga lokushisa eliphezulu lokusebenza ngu-60℃
Ivalve yepulasitiki (NBR, NEoprene diaphragm valve)
Izinga lokushisa eliphezulu lokusebenza ngu-80℃
I-valve yepulasitiki (i-fluorine rubber diaphragm valve)
Izinga lokushisa eliphezulu lokusebenza 200 ℃
Uma irabha nepulasitiki kusetshenziswa ulwelwesi lwama-valve, ukumelana nezinga lokushisa kwerabha nepulasitiki kuzoba namandla.
I-valve ye-Ceramic, ngenxa yokumelana kwayo okuphansi kwezinga lokushisa, ngokuvamile isetshenziswa ezimweni zokusebenza ezingaphansi kuka-150 ℃. Muva nje, kuvele i-valve ye-ceramic esebenza kahle kakhulu, ekwazi ukumelana namazinga okushisa angaphansi kuka-1000 ℃.
I-valve yengilazi. Ukumelana nezinga lokushisa okungalungile, ngokuvamile okusetshenziselwa izimo zokusebenza ezingaphansi kuka-90 ℃.
I-valve yoqweqwe lwawo, ukusebenza kwezinga lokushisa kukhawulwe yindandatho yokuvala uphawu, izinga lokushisa eliphakeme lokusebenza alidluli ku-150 ℃.
Izinto zokwakha ze-valve zifaka phakathi: C carbon steel, I 1Cr5Mo chromium-molybdenum steel, H Cr13 series steel stainless, K malleable cast iron, L aluminium alloy, P 0Cr18Ni9 series steel stainless, PL 00Cr19Ni10 series steel stainless steel, Q nodular iron 0Cr12Ni12Mo2 uchungechunge lwensimbi engagqwali, RL 00Cr17Ni14Mo2 uchungechunge lwensimbi engagqwali, amapulasitiki e-S, T copper kanye nengxubevange yethusi, Ti titanium ne-titanium alloy, V chromium molybdenum vanadium steel, Z grey cast iron.
Ukuhlanganiswa kwe-valve nokuhlakazwa kuhlonza intambo yesokunxele nesokudla
Ukuhlonza kahle ukuthi intambo ikwesokunxele noma kwesokudla kuwulwazi oluyisisekelo kakhulu lokuhlanganisa ama-valve nokuqaqa. Ngakho uthola kanjani ukuthi intambo ikwesokunxele noma kwesokudla?
Inganqunywa ngentambo yangaphakathi noma yangaphandle ku-valve. Ngokuvamile, zingezokwakhiwa kwentambo emihle nengalungile ukuvimbela ukuxegiswa kwentambo. Okufana nesiqu, ukuxhumana kwe-stem nut: indandatho eqinile ku-stem nut izungeza kwesokunxele, intambo esondweni lesandla izungeza kwesokudla, intambo ye-trapezoidal ku-stem nut iwukuzungezisa kwesokunxele. Ngaphezu kwalokho, i-Angle ekhuphukayo yentambo ingakwesokunxele kwentambo ibizwa ngokuthi kwesokunxele; Uma kungenjalo, i-dextral rotation.
