Iindidi ezi-6 zevalve yebhabhathane yokutywina ethambileyo

Njengenxalenye esetyenziselwa ukuqaphela i-on-off and flow control of the pipeline system, ivalve yebhabhathane etywiniweyo isetyenziswe ngokubanzi kwiindawo ezininzi ezifana ne-petroleum, i-chemical industry, i-metallurgy, i-hydropower njalo njalo.Icwecwe levalve yebhabhathane yokutywina ethambileyo ifakwe kwicala elithe nkqo kumbhobho.Kwi-cylindrical passage ye-butterfly valve body, i-disc-shaped butterfly plate ijikeleza i-axis, kwaye i-angle yokujikeleza iphakathi kwe-0 ° kunye ne-90 °.Xa ijikeleza kwi-90 °, i-valve ivuleke ngokupheleleyo.

1. Ukuhlelwa ngokutywinwa kwezinto ezingaphezulu

1) Ivalve yebhabhathane etywiniweyo ethambileyo: Ukutywinwa kwenziwa ngento ethambileyo engeyiyo eyentsimbi ukuya kwimathiriyeli ethambileyo engeyiyo eyentsimbi.

2) Ivalve yebhabhathane yokutywina eqinileyo yentsimbi: Isibini sokutywina senziwe ngezinto eziqinileyo zentsimbi ukuya kwizinto eziqinileyo zetsimbi.

2. Ukuhlelwa ngokwesakhiwo

1) Ivalve yebhabhathane yokutywina embindini

2) Ivalve yebhabhathane yokutywina enye eccentric

3) Ivalve yebhabhathane yokutywina kabini eccentric

4) Ivalve yebhabhathane yokutywina kathathu eccentric

3. Ukuhlelwa ngokutywinwa kwefom

1) Ivalve yebhabhathane yokutywina ngokunyanzeliswa: Ukutywinwa kuveliswa yipleyiti yevalve ecinezela isitulo sevalvu xa ivalve ivaliwe, kunye nokunwebeka kwesitulo sevalve okanye ipleyiti yevalvu.

2) Ivalve yebhabhathane esetyenzisiweyo yokutywina: ukutywina kuveliswa yitorque efakwa kwivalve shaft.

3) Ivalve yebhabhathane etywinwa ngoxinzelelo: Ukutywinwa kuveliswa ngokutshaja kwento etywiniweyo yokutywina kwisitulo sevalve okanye kwipleyiti yevalvu.

4) Ivalve yebhabhathane yokutywina ngokuzenzekelayo: ukutywinwa kuveliswa ngokuzenzekelayo ngoxinzelelo oluphakathi.

4. Ukuhlelwa ngoxinzelelo lomsebenzi

1) Vacuum butterfly valve: Ivalve yebhabhathane enoxinzelelo lomsebenzi olungaphantsi kunoxinzelelo oluqhelekileyo lomoya.

I-2) I-valve ye-butterfly ephantsi yoxinzelelo: i-valve ye-butterfly ene-PN ye-PN <1.6MPa.

3) Ivalve yebhabhathane yoxinzelelo oluphakathi: ivalve yebhabhathane ene-PN yoxinzelelo lwegama le-2.5 ukuya kwi-6.4MPa.

I-4) I-valve ye-butterfly yoxinzelelo oluphezulu: i-valve ye-butterfly ene-PN ye-PN ye-10.0 ukuya kwi-80.0MPa.

5) Ivalve yebhabhathane yoxinzelelo oluphezulu: Ivalve yebhabhathane enoxinzelelo lwegama PN>100MPa.

5. Ukuhlelwa ngendlela yokudibanisa

1) Ivalve yebhabhathane yeWafer

2) Ivalve yebhabhathane eFlanged

3) Lug butterfly valve

4) Ivalve yebhabhathane edibeneyo

6. Ukuhlelwa ngobushushu bokusebenza

1) Ivalve yebhabhathane lobushushu obuphezulu: >450℃

2) Ivalve yebhabhathane lobushushu obuphakathi: 120℃

3) Ivalve yebhabhathane yobushushu obuqhelekileyo: -40℃

4) Ivalve yebhabhathane lobushushu obuphantsi: -100℃

5) Ivalve yebhabhathane yobushushu obuphantsi kakhulu: <-100℃
