Yakaputirwamavharuvhu egedhiimhando yevharuvhu yegedhi yakabatana nemaflange. Anonyanya kuvhura nekuvharwa nekufamba kwakamira kwegedhi riri pakati penzira uye anoshandiswa zvakanyanya mukudzora kuvharwa kwemasisitimu emapaipi.

(Mufananidzo:Valve yegedhi yesimbi yeCarbon flangedDN65)

Mhando dzayo dzinogona kuiswa muzvikamu zviviri zvichienderana nehunhu hwechimiro: zvichienderana nechimiro chegumbo regedhi, kune mhando dzegumbo rakavhurika nedzinovigwa. Kana vharuvhu yegedhi resimbi rakavhurika rakavhurika kana kuvharwa, guruvhu rinobuda kubva pakavhavha, zvichibvumira kutariswa zvakananga kwedanho rekuvhura. Rakakodzera mamiriro ezvinhu anoda kutariswa panguva chaiyo, senge nzvimbo dzemvura dzemumaguta nenzvimbo dzekupomba mvura. Guruvhu reguruvhu regedhi rakavigwa haripfuuri kavhavha. Rine chimiro chakamanikana uye rakakodzera zviitiko zvine nzvimbo shoma senge pasi pevhu matsime emapaipi nemiti yemakemikari ine michina yakawanda. Zvichienderana nechimiro cheguruvhu, kune mhando yewedge nerudzi rweparallel. Guruvhu regedhi rakaumbwa sewedge, rine chisimbiso chakasimba, uye rakakodzera mamiriro ekushanda ari pakati nepakati nepamusoro (PN1.6~16MPa). Pakati pawo, guruvhu regedhi rakapfava rinogona kutsiva musiyano wekupisa uye rinowanzo shandiswa mumapaipi ekufambisa emhepo nemafuta anopisa. Mapureti egedhi akapfava ane mativi maviri akaenzana uye akavharwa nekumanikidzwa kwemedium. Anonyanya kushandiswa muzvinhu zvine simba shoma uye dhayamita hombe zvine dhayamita yeDN300 kana kupfuura, zvakaita semapaipi makuru emvura. Ane simba shoma rekuvhura nekuvhara uye akakodzera kushandiswa kakawanda.

Mukushandiswa kwayo, nekuda kwekugadzikana kwayo kwakanyanya uye kushanda kwayo kwekubatanidza maflange, inoshandiswa zvakanyanya mumaindasitiri mazhinji: mhando yetsvimbo yakavanzika kana kuti parallel gate plate inowanzo shandiswa mumabasa emumaguta nekuvaka ekugovera mvura nekudhonza mvura, pamwe nemapaipi ekudzivirira moto. Muindasitiri yepetrochemical, mavharuvhu egedhi re wedge anowanzo shandiswa mumapaipi ekutakura mafuta asina kuchena uye zvigadzirwa zvemafuta akacheneswa pasi pemamiriro ekumanikidzwa kwakanyanya. Mundima yesimba nesimba, mavharuvhu egedhi re elastic wedge ane resistance iri nani yekupisa anowanzo sarudzwa emvura inotonhorera yechiteshi chemagetsi nemapaipi emhepo anodziya muboiler. Mavharuvhu egedhi re parallel ane resistance yakasimba yekusvibiswa akakodzera mvura yakasviba yeindasitiri uye masisitimu emvura anotenderera musimbi nekurapa mvura. Pakusarudza, kumanikidzwa, nzvimbo uye hunhu hwepakati zvinofanirwa kutariswa. Kushanda kwayo kwakavimbika kunoita kuti ive chikamu chikuru chekudzora masisitimu epaipi mumaindasitiri akasiyana-siyana.

Rudzi rwemavharuvhu egedhi ane flange runofanira kufungwa nezvekumanikidzwa, nzvimbo uye hunhu hwepakati. Kushanda kwayo kwakavimbika kwekuvhara kunoita kuti ive chinhu chikuru chekudzora mumasisitimu emapaipi emaindasitiri akasiyana-siyana. Kana muine zvimwe zvinodiwa, ndapota taurai nesu pazasi. Semugadziri wemavharuvhu egedhi eIndasitiri ane makore makumi maviri, Jinbin Valve inokupai mhinduro dzehunyanzvi. (Gate Valve Nemitengo)
