Isingeniso sezinto ze-ball valve

Izinto ze-ball valve ziyahlukahluka ukuze zivumelane nezimo zokusebenza ezahlukene kanye nezidingo zemidiya. Okulandelayo ezinye zezinto ze-ball valve ezivamile kanye nezici zazo:

1. Izinto zensimbi ezibunjiwe

Insimbi empunga: ifanelekela amanzi, umusi, umoya, igesi, uwoyela kanye nezinye izinto ezisebenzisa ukucindezela okujwayelekile okungu-PN≤1.0MPa kanye nokushisa okungu--10℃ ~ 200℃. Izinhlobo ezivame ukusetshenziswa yi-HT200, HT250, HT300, HT350.

Insimbi ethambile: ifanelekela amanzi, umusi, umoya kanye nendawo yamafutha enengcindezi ejwayelekile PN≤2.5MPa kanye nokushisa -30℃ ~ 300℃. Izinhlobo ezivame ukusetshenziswa yi-KTH300-06, KTH330-08, KTH350-10.

Insimbi ethambile: Ifanelekela i-PN≤4.0MPa, izinga lokushisa -30℃ ~ 350℃ amanzi, umusi, umoya namafutha kanye nezinye izinto ezisetshenziswayo. Amazinga avame ukusetshenziswa yi-QT400-15, QT450-10, QT500-7. Ngaphezu kwalokho, insimbi ethambile ene-silicon ephezulu engamelana ne-asidi ifanelekela izinto ezisebenzisa izinto ezibolayo ezinengcindezi encane ye-PN≤0.25MPa kanye nezinga lokushisa elingaphansi kuka-120℃.

2. Insimbi engagqwali

I-valve yebhola yensimbi engagqwali isetshenziswa kakhulu kumapayipi anomfutho ophakathi nendawo kanye nowezinga lokushisa eliphezulu, enokumelana okunamandla nokushisa, futhi isetshenziswa kabanzi ezimbonini zamakhemikhali, ze-petrochemical, ze-smelting kanye nezinye izimboni. Izinto zensimbi engagqwali zinokumelana okuhle nokugqwala kanye namandla okushisa aphezulu, zifanelekela izinhlobo ezahlukene zemidiya egqwali kanye nendawo enokushisa okuphezulu.

3. Izinto zethusi

Ingxube yethusi: Ifanelekela amanzi e-PN≤2.5MPa, amanzi olwandle, umoya-mpilo, umoya, uwoyela nezinye izinto, kanye nokushisa kwe--40℃ ~ 250℃ steam medium. Amazinga asetshenziswa kakhulu yi-ZGnSn10Zn2(tin bronze), i-H62, i-Hpb59-1(brass), i-QAZ19-2, i-QA19-4(aluminium bronze) njalo njalo.

Ithusi lokushisa eliphezulu: ifanelekela umusi kanye nemikhiqizo kaphethiloli enengcindezi encane engu-PN≤17.0MPa kanye nezinga lokushisa elingu-≤570℃. Izinhlobo ezivame ukusetshenziswa yi-ZGCr5Mo, 1Cr5Mo, ZG20CrMoV njalo njalo.

4. Izinto zensimbi yekhabhoni

Insimbi yekhabhoni ifanelekela amanzi, umusi, umoya, i-hydrogen, i-ammonia, i-nitrogen kanye nemikhiqizo kaphethiloli enengcindezi ejwayelekile engu-PN≤32.0MPa kanye nokushisa -30℃ ~ 425℃. Amazinga asetshenziswa kakhulu yi-WC1, i-WCB, i-ZG25 kanye nensimbi yekhwalithi ephezulu engu-20, 25, 30 kanye nensimbi yesakhiwo ephansi engu-16Mn.

5. Izinto zepulasitiki

I-valve yebhola yepulasitiki yenziwe ngepulasitiki yezinto zokusetshenziswa, ezifanelekela ukuvinjelwa kwenqubo yokudlulisa ngemidiya ebolile. Amapulasitiki asebenza kahle njenge-PPS ne-PEEK avame ukusetshenziswa njengezihlalo zamavalve ebhola ukuqinisekisa ukuthi uhlelo alugugi ngamakhemikhali akhona ngokuhamba kwesikhathi.

6. Izinto zobumba

I-valve yebhola le-ceramic uhlobo olusha lwezinto ze-valve, enokumelana okuhle kakhulu nokugqwala kanye nokumelana nokuguguleka. Ubukhulu begobolondo le-valve budlula izidingo zendinganiso kazwelonke, futhi izakhi zamakhemikhali kanye nezakhiwo zemishini zezinto eziyinhloko zihlangabezana nezidingo zendinganiso kazwelonke. Njengamanje, isetshenziswa ekukhiqizeni amandla okushisa, insimbi, uphethiloli, ukwenza iphepha, ubunjiniyela bezinto eziphilayo kanye neminye imboni.

7. Izinto ezikhethekile

Insimbi enezinga lokushisa eliphansi: ifanelekela ingcindezi ejwayelekile ye-PN≤6.4MPa, izinga lokushisa ≥-196℃ i-ethylene, i-propylene, igesi yemvelo ewuketshezi, i-nitrogen ewuketshezi kanye nezinye izinto. Izinhlobo ezivame ukusetshenziswa yi-ZG1Cr18Ni9, 0Cr18Ni9, 1Cr18Ni9Ti, ZG0Cr18Ni9 njalo njalo.

Insimbi engagqwali engamelana ne-asidi: ifanele i-nitric acid, i-acetic acid kanye nezinye izinto ezisebenzisa ingcindezi ye-nominal PN≤6.4MPa kanye nokushisa ≤200℃. Izinhlobo ezivamile yi-ZG0Cr18Ni9Ti, ZG0Cr18Ni10 (ukumelana ne-nitric acid), ZG0Cr18Ni12Mo2Ti, ZG1Cr18Ni12Mo2Ti (ukumelana ne-asidi kanye ne-urea) njalo njalo.

Ngamafuphi, ukukhethwa kwezinto zevalvu yebhola kufanele kunqunywe ngokuya ngezimo zokusebenza ezithile kanye nezidingo eziphakathi ukuqinisekisa ukusebenza okuvamile kanye nokuqina kwesikhathi eside kwevalvu.
