Kukho iintlobo ezintathu zoxinzelelo oluphezuluukutywinwa kweflangeumphezulu: umphezulu wokutywina wenqwelomoya, olungele uxinzelelo oluphantsi, amathuba eendaba angeyotyhefu; Umphezulu weconcave kunye neconvex yokutywina, ilungele iimeko zoxinzelelo oluphezulu kancinci; Umphezulu wokutywina we-Tenon groove, olungele ukutsha, uqhushumbo, indawo eyityhefu kunye nezihlandlo zoxinzelelo oluphezulu.
Ububanzi boqhagamshelwano lweiflange yoxinzelelo oluphezului-gasket kunye nokutywinwa komhlaba kumxinwa kakhulu (uqhagamshelwano lomgca), kunye nokugqitywa kokulungiswa kwendawo yokutywina kunye ne-gasket iphezulu. I-flange edibeneyo eqhelekileyo ineflat welding flangekwayebutt welding flange. I-gasket yerabha eqhelekileyo ilungele ithuba lobushushu obungaphantsi kwe-120℃; Igasket yerabha ye-asbestos ilungele ubushushu bomphunga wamanzi ungaphantsi kwe-450 ℃, ubushushu be-oyile bungaphantsi kwe-350℃, uxinzelelo lungaphantsi kwezihlandlo ze-5MPa, kwi-corrosive medium, eyona isetyenziswa kakhulu yipleyiti ye-asbestos ekwaziyo ukumelana ne-asidi.

Uxinzelelo oluphantsi ububanzi obuncinciiflange enemisonto, uxinzelelo oluphezulu kunye noxinzelelo oluphantsi ubukhulu obukhuluiflange edityanisiweyo, iflangeubukhulu kunye nokudibanisa ibholithi ububanzi kunye nenani loxinzelelo oluhlukeneyo lwahlukile.
Uninzi gaskets zigawulwe phantsi iipleyiti non-metallic, okanye ezenziwe ziifektri professional ngokungqinelana nobukhulu obuchaziweyo, izinto zayo irabha sheets asbestos, asbestos sheets, polyethylene sheets, njl Kwakhona luncedo ipleyiti yentsimbi ebhityileyo (intsimbi yentsimbi, i-stainless). intsimbi) iasbestos kunye nezinye izinto ezingezizo ezentsimbi ezisongelwe zenziwe ngegasket yentsimbi; Kukwakho ne-gasket ejikelezayo eyenziwe ngeteyiphu yentsimbi encinci kunye neteyiphu yeasbestos eboshwe kunye.
Uxinzelelo oluphezulu lweflangeuqhagamshelwano luqhagamshelo oluqhawukayo. Ngokutsho kwamacandelo adibeneyo anokwahlulwa abeisikhongozeli flangekwayeumbhobho flange. Ngokwesakhiwo, kukhoiiflange ezidibeneyo,looping flangeskwayeiiflange ezinemisonto.
Kwizixhobo zoxinzelelo oluphezulu kunye nemibhobho, ukusetyenziswa kobhedu, i-aluminium, akukho. Intsimbi eyi-10, insimbi engenasici eyenziwe yohlobo lwe-lens okanye enye imilo yeegasket zetsimbi. Ukuqina koxinzelelo oluphezulu lweflange luhlwempuzekileyo, lufanelekile kuxinzelelo lwe-P ≤4MPa izihlandlo; I-Flange yoxinzelelo oluphezulu, eyaziwa ngokuba yi-high neck flange, iqinile ngakumbi, ilungele uxinzelelo oluphezulu kunye nezihlandlo zokushisa. Uxinzelelo oluphezulu lwe-flange gasket luhlobo lwendandatho enokuvelisa deformation yeplastiki kwaye inamandla athile.
