Circular flangingnon-metallic kuwedzera jointuye rectangular isiri-simbi ganda imhando yeganda risiri resimbi.Kuenzaniswa neyakajairwa hemming yekuwedzera ganda rejoinhi, panguva yekugadzira, musangano unofanirwa kuita denderedzwa kana masikweya makona kuti zvive nyore kuisirwa zvinoenderana nemadhirowa.Nzira yekugadzira yakanyanya kuoma.Isiri-simbi ganda rudzi rutsva rwepamusoro-tekinoroji yekupisa yekuvharisa zvinhu inoumbwa negirazi fiber jira uye silica gel yakavharwa girazi fiber jira uye mamwe asingapindire moto uye yakakwirira tembiricha inodzivirira jira.Zvichienzaniswa nezvinhu zvesimbi, kushanda kwakazara kwezvinhu zvisiri zvesimbi zvakadai sekukwirira kwekushisa kwekushisa, asidi uye alkali kuramba uye kugadzikana kwemakemikari kwakapfuura nepamusoro pezvinhu zvesimbi.Izvo zvakashata zvezvisina-metallic flexible machira ematehwe ndezvekuti hazvigone kushandiswa munzvimbo dzakanyanya kudzvanywa.Kazhinji kutaura, munzvimbo dzinopfuura 0.5mpa, zvinodikanwa kufunga kushandisa majoini ekuwedzera esimbi kana asiri-metallic rubber majoini ekuwedzera panzvimbo.
Nzira yekuenzanisa sei isiri-simbi yekuwedzera majoini?
1. Mabhoti eflange anofanira kusimbiswa zvishoma nezvishoma uye zvakafanana, uye kusungirirwa kwemabhoti kunofanira kunge kwakafanana sezvinobvira.Mumamiriro ezvinhu akaoma, chitubu chisina simba chinogona kuwedzerwa kuwedzera kune flat washer kudzivirira kuti nut irege kusunungurwa.
2. Iyo inoenderana nerabha asbestos gasket inofanira kushandiswa kutanga maererano nekushanda kwekushisa pakati pejoint yekuwedzera uye inofananidzwa flat welding flange.
3. Munguva yekuedza, iyo muganhu screw yejoint yekuwedzera inofanira kugadziriswa zvakanaka kuti ifambise kuwedzera kana kudzvinyirira kwechigadzirwa.
4. Kana iyo welded pombi yabatanidzwa, iyo yekumisa screw inofanirwa kusunungurwa zvakanaka kudzivirira iyo inogumira ndiro yejoinhi rekuwedzera kubva pakukotama kana kuti chigadzirwa chakaremara.
5. Panguva yekushanda kwekugadzira, inoshandiswa sevhavha yekuvhara pamusoro pe rubber (mucheka) kudzivirira welding slag kubva pakukuvadza chigadzirwa.
