Traditionalbanga gedhi mavharuvhukuita zvakanaka mu unidirectional flow control, asi kazhinji pane njodzi yekudonha kana yakatarisana nebidirectional kuyerera. Pahwaro hwechinyakare chekucheka-vharavhavhavha, kuburikidza nekutsvagisa nekusimudzira, chigadzirwa chakakwidziridzwa, uye chigadzirwa chitsva "nzira mbiri dzakapfava seal plug valve" yakasimudzirwa kuti ive nechokwadi chekuti chisimbiso chinoshanda che zero leakage inogona. kuwanikwa mune chero nzira yekuyerera.

Iyo nyowani dhizaini inoshandura kuiswa kwechisimbiso rabha, kutsiva groove rubber strip panesluice gedhi vharafumuviri une rabha elastiki, iro rakaputirwa nemuviri wevharuvhu. Iyi mukana ndeyekugadzirisa dambudziko rekutsiva kwakaoma mushure mekuvhara kurasikirwa, kana kurasikirwa kwechisimbiso, kunogona kutsiviwa panzvimbo, kuisirwa nyore, nyore disassembly uye mabhenefiti ekugadzirisa, kudzikisa kukanganisa pachirongwa chekugadzira.

Pamusoro pezvo, iyo imwechete yekuisa chisimbiso rubber strip inoshandurwa kuita maviri-nzira yekuisa chisimbiso uye kaviri-layer sealing tambo kugadzirisa zvipingamupinyi zvekusamanikidzwa kudzosera kumashure, kungaveflanged gedhi vharafundiro inosimbiswa kumberi kana kutungamira kwekumanikidza, iyo elastic deformation yerabha inogona kushamwaridzana neplate yevharuvhu, kuwana nzira mbiri yekuisa chisimbiso, kunatsiridza chisimbiso, uye kuwana zero kuvuza.

Chigadzirwa chedu chitsva chebidirectional sealing banga simbi gedhi vharafu chakakodzera mvura yepombi, tsvina, indasitiri yekuchenesa mvura, chinhu chikuru chiri kuyerera-chisimbiso, bidirectional pressure, inogona kuzadzisa bidirectional chisimbiso, chisimbiso chepamusoro. Haisi nyore kubuda kunze, ine nzvimbo diki yekuisa, yakaderera kushanda kudzvanywa, haisi nyore kuunganidza marara, high pressure gedhi harina vibration, hapana ruzha, linear chiteshi, kuyerera kudiki kuramba, hapana kudzvanywa mutsauko kurasikirwa, kana gedhi riripo. yakavharwa, iyo inovimbika yepakati pressure inosundira kumanikidza kwegedhi kune rumwe rutivi rwechisimbiso gedhi revhavha chigaro kuti ive nechokwadi chekuisa chisimbiso pamusoro. Ichi chitsva hachingogadziri zvakanyanya kusimba uye kuvimbika kwevhavha, asiwo zvakanyanya kuderedza kurasikirwa kwesimba uye kusvibiswa kwezvakatipoteredza kunokonzerwa nekudonha. Mushure mekuonekwa kwebidirectional sealing banga mavharuvhu egedhi, nhamba huru yemavharuvhu akachekwa akatsiviwa nawo.
