Yiziphi izindawo zemidiya ezifaneleke kuzo amavalvu ovemvane?

Ama-valve e-Butterfly, ngenxa yezinhlaka zazo ezihlukene kanye namafomu okuvala aguquguqukayo, angakwazi ukuzivumelanisa nezimo ezihlukahlukene zemidiya futhi angahlukaniswa ngokuqondile ngezigaba ezilandelayo:

1, Universal Media Environment

Izixazululo zamanzi namanzi

Ifanele imidiya esekwe emanzini njengamanzi ahlanzekile, indle, amanzi olwandle, amanzi anosawoti, njll. Isibonelo, i-centerlineuvemvane valveingafinyelela ku-zero ukuvaleka kokuvaleka emanzini ahlanzekile, indle, nezindawo zamanzi olwandle ukusuka ku -10 ℃ kuya ku-150 ℃, futhi ivamise ukusetshenziswa ezindaweni zokuhlanza amanzi, ukuphakelwa kwamanzi kamasipala, kanye nezinhlelo zokudonsa amanzi.

I-Gas medium

Ifanele amagesi anjengomoya, igesi yemvelo, igesi yamalahle, isitimu, njll. Ivalve uvemvane wevacuum ingakwazi ukuphatha umoya ohlanzekile namagesi angagqwali, ngezinga lokushisa elingu-≤ 300 ℃ kanye nengcindezi engu-0.1MPa; Amavalvu ovemvane womoya womoya asetshenziselwa imidiya efana namagesi anothuli namagesi aphumayo, futhi afanele ukulawulwa koflue kubhayela kanye nobunjiniyela bemvelo.

Amafutha medium

Ifanele uwoyela ongahluziwe, uwoyela ocolisisiwe, uwoyela wokugcoba namanye amafutha. Amavalvu ovemvane avaliwe ngensimbi (njengama-valve evemvane eccentric kathathu) angakwazi ukumelana nezinga lokushisa eliphezulu nokucindezela okukhulu, futhi avame ukusetshenziswa kumapayipi athutha uwoyela ezimbonini ze-petroleum ne-petrochemical.

2, Special medium imvelo

i-corrosive medium

Isixazululo se-alkali ye-Acid: Amavalvu ovemvane ane-fluorine afakwe ulayini kanye namavalvu evemvane anerabha enziwe ngezinto ezimelana nokugqwala (njenge-polytetrafluoroethylene nerabha), alungele imidiya egqwala kakhulu njenge-sulfuric acid, i-hydrochloric acid, ne-sodium hydroxide.

I-Chemical medium: Isihlalo samavalvu e-eccentric metal esiqinile esivalwe ngokuqinile esishiselwe nge-alloy engashi futhi ukumelana nokugqwala, esikwazi ukuphatha amagesi okugqwala noketshezi olufana ne-chlorine ne-hydrogen chloride.

Izinhlayiya kanye nemidiya yezinto eziqinile ezimisiwe

Isakhiwo sokubeka uphawu esinwebekayo se-centerlineuvemvane valveingakwazi ukuzivumelanisa ne-semi fluid kanye nemidiya ye-granular (njengodaka, i-pulp, impushana eyomile), igwema ukuvinjelwa noma ukuguga, futhi ivame ukusetshenziswa ezimbonini ezifana nezimayini, i-metallurgy, kanye nokwenza amaphepha.

Izinga lokushisa eliphezulu kanye ne-high pressure medium

Ivalvu yevemvane eyi-eccentric yamukela ukwakheka kwe-eccentric enezinhlangothi ezintathu, enokumelana nezinga lokushisa okungaphezu kuka-600 ℃ kanye nokumelana nokucindezela kwe-PN40 (4.0MPa), ifanele izinga lokushisa eliphezulu nezimo zengcindezi ephezulu njengamandla okukhiqiza amandla ashisayo namayunithi okuqhekeka kwe-petrochemical.

3. Imidiya ehlanzekile nebanga lokudla

Amavalvu ovemvane ebanga lokudla enziwe ngezinto ezingenabo ubuthi, ezingenaphunga, nezihlanzeka kalula (njengensimbi engagqwali, i-UPVC), ezithobela izindinganiso ze-GMP futhi afanele amapayipi ahlanzekile ezimbonini ezifana nokudla, iziphuzo, nemithi ukuze kugwenywe ukungcoliswa okumaphakathi.
