Kuisa chisimbiso chevhavha tekinoroji yepasirese yakakosha kune akasiyana maindasitiri zvikamu. Haisi chete zvikamu zvakaita se petroleum, makemikari, chikafu, mishonga, kugadzira mapepa, simba remvura, kuvaka ngarava, mvura uye dhiraivha, kunyungudutswa, uye simba rinotsamira pane yekuisa chisimbiso tekinoroji, asi maindasitiri ekucheka-kumucheto sendege uye aerospace zvakare akabatana nazvo.
Inowanzo shandiswa valve sealing materials
Rubber Material:Rubber ndechimwe chezvinonyanya kushandiswa zvisimbiso zvevharuvhu, kunyanya mushavishavivharafuuyegedhi mavharuvhu. Mhando dzerabha dzakajairika dzinosanganisira Neoprene Rubber, viton, uye silicon rabha. Izvi zvinhu zvinopa yakanakisa elasticity uye corrosion resistance, zvichiita kuti dzive dzakakodzera kuvharisa zvakasiyana-siyana zvenhau.
Telflon(PTFE):PTFE ndeyepamusoro-inoshanda epurasitiki zvinhu zvakanyanya kushandiswa mumavharuvhu zvisimbiso. Yayo yakanakisa kemikari uye tembiricha kuramba inoita kuti ive yakakodzera kushandiswa munzvimbo dzine tembiricha yakanyanya, kudzvanywa kwakanyanya, uye corrosive media. PTFE zvisimbiso zvinowanzoshandiswa mukaticheki mavharuvhuuyebutterfly valves.
Metal:Metal seals anoshandiswawo zvakanyanya mune mamwe hunyanzvi maapplication. Zvisimbiso izvi zvinowanzogadzirwa nesimbi isina tsvina, mhangura, kana mamwe maalloys uye akakodzera kuvhara mavharuvhu mukupisa kwepamusoro-soro, kudzvanywa kwepamusoro, uye kwakanyanyisa nharaunda. Zvakanakira zvisimbiso zvesimbi zviri mukugara kwavo uye kugadzikana kwenguva refu.
Composite zvinhu:Zvinhu zvakaumbwa zvakawedzera kutariswa mumakore achangopfuura. Izvi zvinhu zvinowanzobatanidza zvakanakira rabha uye epurasitiki, zvichipa yakanakisa yekuisa chisimbiso kuita pasi peakasiyana ekushanda mamiriro. Kushandiswa kwezvinhu zvakasanganiswa kwakawedzera kuvandudza kushanda kwekuvhara kwemavharuvhu.
Valve sealing material performance zviratidzo
Paunosarudza zvisimbiso zvevhavha, zvinotevera zvinongedzo zvekuita zvinofanirwa kutariswa:
TembirichaRkuramba:Iyo tembiricha yemhando yekuisa chisimbiso chiratidzo chakakosha chekuongorora maitiro ayo. Zvinhu zvakasiyana-siyana zvine madhigirii akasiyana-siyana ekudzivirira kupisa. Zvishandiso zverabha zvinowanzokodzera kudziya kwakadzikira, nepo PTFE uye simbi zvinhu zvakanyanyokodzera kune yakakwirira-tembiricha application.
CorrosionRkuramba:Mavharuvhu anowanzo shandiswa kutakura akasiyana emakemikari midhiya, saka kuramba kwecorrosion kwechinhu chekuisa chisimbiso kwakakosha. PTFE uye mamwe marubha akasarudzika anokunda panhau iyi, achidzivirira kugwinya kubva mumhando dzakasiyana dzemakemikari.
Compression Set:Izvi zvinoyera kugona kwechinhu chekuisa chisimbiso chekuchengetedza zvisimbiso zvayo pasi pekumanikidzwa kwenguva refu. Iyo diki yekumanikidza seti, zviri nani kuita chisimbiso chechinhu.
Elasticity& Rkubudirira:Iyo elasticity uye kusimba kweiyo yekuisa chisimbiso inokanganisa zvakananga kuita kwayo yekuisa chisimbiso. Yakanaka elasticity inovimbisa kuti mhete yekuisa chisimbiso inogona kunyatsokwana kana vharuvhu yakavhurwa uye yakavharwa, kudzivirira kubuda.
Kuramba kupfeka:Mune mamwe maapplication, mavharuvhu ekuisa chisimbiso zvinhu zvinoda kumira kupfeka, saka kupfeka kuramba chinhu chakakosha kuita chiratidzo. Metal zvisimbiso uye zvimwe zvinhu zvinoumbwa zvinoita zvirinani mune izvi.
Mhedziso
Kusarudza chinhu chakakodzera chekuisa chisimbiso kwakakosha pakuita kwevharuvhu.TWSachanyanya kusumabutterfly valves, gedhi mavharuvhu,uyecheki mavharuvhu, pakati pezvimwe, imwe neimwe ichishandisa chaiyo yekuisa chisimbiso zvinhu zvinoenderana nebasa rayo. Kunzwisisa zviratidzo zvekushanda kwezvinhu zvakasiyana kunopa mainjiniya simba rekuita sarudzo dzine ruzivo kana achigadzira nekuchengetedza mapombi masisitimu, nekudaro kuve nechokwadi chekushanda kwakachengeteka uye kwakanaka.
