Ndeapi maitiro akajairika epaflange sealing surfaces?

1. Chiso Chakazara (FF):
Iyo flange ine nzvimbo yakatsetseka, yakapusa chimiro, uye nyore kugadzirisa.Inogona kushandiswa mumamiriro ezvinhu apo kudzvinyirirwa hakusi kwakakwirira kana kuti kutonhora hakuna kukwirira.Zvisinei, nzvimbo yekubatana pakati pekuvhara pamusoro uye gasket yakakura, inoda simba guru rekumanikidza.Panguva yekuisa, iyo gasket haifanirwe kuiswa, uye mushure mekutanga kuomesa, iyo gasket iri nyore kuwedzera kana kutama kumativi ese.Paunenge uchishandisa mitsara yakatsetseka kana isiri-metallic flanges, iyo FF yepamusoro flange inova nechokwadi chekuti chisimbiso chepamusoro hachiputsi panguva yekuomesa, kunyanya iyo FF pamusoro.

2 Yakasimudza Chiso (RF):
Iine chimiro chakareruka uye chiri nyore kugadzirisa, uye inogona kushandiswa mumamiriro ezvinhu apo kudzvinyirira hakuna kunyanya kukwira kana kutonhora hakuna kunyanya.Nekudaro, vamwe vanhu vanotenda kuti kushandisa gaskets pasi pekumanikidzwa kwakanyanya kunogoneka.
Nekuda kwekumisikidzwa kwayo kuri nyore, iyi flange inzira inoshandiswa zvakanyanya yekuisa chisimbiso pazasi pePN 150.

3. Chiso cheMurume neMunhukadzi (MFM):
Inosanganisira concave uye convex nzvimbo, gasket rinoiswa pamusoro concave pamusoro.Kuenzaniswa neflange flanges, concave convex flange gaskets hainyanyi kumanikidzana, iri nyore kuunganidza, uye ine yakakura kushanda kudzvanywa pane.flat flanges, zvichiita kuti dzive dzakakodzerwa nezvinodiwa zvekuisa chisimbiso zvakasimba.Nekudaro, kune michina ine tembiricha yakakwira yekushanda uye madhayamita makuru ekuvhara, vamwe vanhu vanotenda kuti gasket inogona kuramba yakasvinwa kana uchishandisa ichi chisimbiso.

4. Kutarisana nerurimi (TG)
Nzira ye mortise groove flange ine groove pamusoro uye groove pamusoro, uye gasket inoiswa mugororo.Kufanana neconcave uye convex flanges, tenon uye groove flanges haitsigire mumagrooves, saka nzvimbo yavo yekumanikidza idiki uye gasket inosimbiswa zvakaenzana.Nekuda kwekuti hapana kudhumhana kwakananga pakati pe gasket nepakati, iyo yepakati haina mhedzisiro pane corrosion uye kumanikidza kweiyo flange sealing surface.Nokudaro, inowanzoshandiswa muzviitiko zvine zvisimbiso zvakasimba zvekuisa chisimbiso chepamusoro, chinopisa, chinoputika, chepfu media, etc. Ichi chisimbiso chepamusoro gasket chiri nyore uye chinobatsira panguva yekuisa, asi kugadzirisa uye kuchinjwa kuchava kwakaoma.

5. Ring Joint Face (RJ)
Iyo flange yekuisa chisimbiso pamusoro pegasket inoiswa mune annular groove.Isa gasket mumhete groove kuitira kuti irege kumanikidzira mugororo, ine nzvimbo duku yekumanikidza uye yunifomu simba pane gasket.Nekuda kwekuti hapana kudhumhana kwakananga pakati pe gasket nepakati, iyo yepakati haina mhedzisiro pane corrosion uye kumanikidza kweiyo flange sealing surface.Naizvozvo, inowanzo shandiswa muzviitiko zvine chisimbiso chakasimba chinodiwa kune yakanyanya kudzvanywa, inopfuta, inoputika, ine muchetura media, nezvimwe.
Muchidimbu, mafomu ekuisa chisimbiso pamusoro pemaflange akasiyana, uye maitiro avo uye mafomu ekushandisa akasiyana.Saka, pakusarudza flange, tinofanira kutarisisa mashandisiro ayo uye kuita zvinodiwa.Somuenzaniso, kana basa racho risina hasha, sarudza aRF chisimbiso pamusoro, uye kana mamiriro ekushanda akaoma, sarudza RJ sealing surface inonyatsozadzisa zvinodiwa zvekuisa chisimbiso;Zviri nani kushandisa FF pamusoro mune isiri-simbi kana yakamisikidzwa flange yakaderera-kudzvanywa mapaipi.Mamiriro ezvinhu chaiwo anoenderana nezvinodiwa chaizvo.
