Center line butterfly vharafu chimwe chezvinhu zvakakosha zvinowanzoshandiswa mumaindasitiri ekudzora fluid masisitimu. Mukushandiswa, kuitira kuti uve nechokwadi chekuvimbika uye kuchengeteka kwegadziriro, zvakakosha zvikuru kusarudza zvakakodzera kuvhara zvinhu. Ichi chinyorwa chichasuma kusarudzwa kwezvinhu zvekuisa chisimbiso uye zvinowanzoshandiswa zvepakati mutsara butterfly valve kuvandudza kuvimbika kwehurongwa.
Kusarudzwa kwechinhu chakakodzera chekuisa chisimbiso chepakati mutsara butterfly valve inoda kufunga zvinotevera: mhando yepakati, tembiricha yemhando, zvinodikanwa zvekumanikidza uye fluid properties. Mamiriro ekushanda akasiyana ane zvinodiwa zvakasiyana zvekuisa chisimbiso, saka zvinhu izvi zvinofanirwa kutariswa zvizere pakusarudza zvinhu.
Chokutanga pane zvose, rudzi rwemidhiya ndechimwe chezvinhu zvinokosha zvinokanganisa kusarudzwa kwezvinhu zvekuisa chisimbiso. Midhiya yakasiyana-siyana ine zvinhu zvakasiyana zvemakemikari, zvakadai seasidhi uye alkali, corrosion uye chepfu. Zvishandiso zvekuisa chisimbiso zvakajairwa zvinosanganisira rabha, mapolymer, simbi uye ceramics. Kune corrosive media, asidhi uye alkali inodzivirira polymer zvinhu zvakaita se polytetrafluoroethylene (PTFE) uye polypropylene (PP) inogona kusarudzwa. Kune yakakwirira tembiricha midhiya, simbi yekuisa chisimbiso zvinhu zvakaita sesimbi isina tsvina isarudzo iri nani.
Chechipiri, tembiricha yemhando zvakare chinhu chinoda kutariswa pakusarudza yakakodzera yekuisa chisimbiso. Zvinhu zvakasiyana-siyana zvine maitiro akasiyana ekushisa. Semuenzaniso, zvinhu zvakajairika zvekuisa chisimbiso zverabha zvinochembera uye kuoma pakupisa kwakanyanya, saka kune yakanyanya tembiricha mamiriro, yakakwirira tembiricha inodzivirira zvinhu senge graphite nesimbi zvinofanirwa kusarudzwa.
Zvinodiwa nedzvinyiriro chimwe chinhu chokufunga nezvacho. Pasi pemamiriro ekumanikidzwa kwepamusoro, zvekuisa chisimbiso zvinoda kuve nepamusoro compressive kuita uye simba. Metal sealing materials kazhinji ine yakanaka compression zvivakwa uye yakakodzera kune yakanyanya kudzvanywa masisitimu. Panguva imwecheteyo, kusimba uye kusimba kwezvinhu zvekuisa chisimbiso kuchakanganisawo kushanda kwayo kwekuvhara, saka zvinodikanwa kusarudza chinhu chine elasticity yakanaka uye kusimba.
Pakupedzisira, zvinhu zvemvura zvinoda kutariswa. Zvimwe zvinwiwa zvine viscosity yakakwirira kana granular matter, uye kurasikirwa kwezvinhu zvekuisa chisimbiso kwakakura. Muchiitiko ichi, zvinhu zvinopikisa kupfeka uye kuora, zvakadai se polyurethane uye magungano erubha, zvinoda kusarudzwa.
Muchidimbu, kusarudzwa kwezvinhu zvekuisa chisimbiso zvepakati mutsara butterfly valve inoda kufunga nezvezvinhu zvakadai sepakati pemhando, tembiricha yemhando, zvinodikanwa zvekumanikidza uye zvinwiwa zvemvura. Kusarudzwa kwezvinhu zvakakodzera zvekuisa chisimbiso zvinogona kunyatsovandudza kuvimbika uye kuchengeteka kwegadziriro uye kuwedzera hupenyu hwebasa revhavhavhavhavhavha. Chekupedzisira, zvinokurudzirwa kubvunza mainjiniya ane hunyanzvi kana matekinoroji akakodzera paunenge uchisarudza zvekuisa chisimbiso kuti uve nechokwadi chekuti zvinhu zvakasarudzwa zvinosangana nemamiriro chaiwo ekushanda.
