Zvinoenderana nechisimbiso chepamusoro zvinhu,gedhi mavharuvhuinogona kukamurwa kuva marudzi maviri: hard seal uye soft seal.Ndeupi musiyano uripo pakati pevhavha yakapfava yekusimbisa uye yakaoma seal valve:
Hard seal gedhi vharafu: Zvishandiso zvekuisa chisimbiso pane ese ekuisa chisimbiso zvinhu zvesimbi, izvo zvinonzi "zvakaoma chisimbiso".Kupikisa kwekushisa kwepamusoro, kupfeka kuramba, kunaka kwemagetsi zvinhu zvakadai se: simbi + simbi;simbi + mhangura;simbi
+ Graphite;simbi + alloy simbi.Zvishandiso zvinowanzoshandiswa zvekuisa chisimbiso ndezvi: 13Cr simbi isina tsvina, yakaoma-yakatarisana yakaoma alloy zvinhu, sprayed tungsten carbide, nezvimwewo.
Soft seal gedhi vharafu: iyo seal pair inogadzirwa nesimbi kune rimwe divi uye elastic isiri-simbi zvinhu kune rimwe divi, iyo inonzi "soft seal".Kuiswa chisimbiso kwerudzi urwu rwechisimbiso kwakanaka, asi hakumirire tembiricha yakakwira, iri nyore kupfeka, uye ine hurombo hwemagetsi zvinhu.Zvakadai se: simbi + rabha;simbi + PTFE, zvichingodaro. Zvinoreva kuti rumwe rutivi rwechisimbiso peya rakagadzirwa nezvinhu zvine kuoma kwakaderera.Kazhinji kutaura, chigaro chakapfava chisimbiso chinogadzirwa nezvinhu zvisiri zvesimbi zvine rimwe simba, kuoma uye tembiricha kuramba.Iyo ine yakanaka yekuisa chisimbiso kuita uye inogona kuwana zero kuvuza, asi ine hupenyu hwakareba.Kuenzaniswa nekusagadzikana kuchinjika kune tembiricha, chisimbiso chakaomarara chakagadzirwa nesimbi, uye kuita chisimbiso kunenge kwakashata, kunyangwe vamwe vagadziri vachiti inogona kuwana zero kuvuza.Chinangwa chekugadzirwa kwevhavha yakapfava yekuisa chisimbiso yegedhi: kugadzirisa dambudziko rechigaro chevharuvhu uye chisimbiso chepamusoro peplate yevharuvhu iri corrode kana kuremara, ndiro yevharuvhu inogona kutsiva otomatiki kuvharika kwakasimba uye kudzvanywa otomatiki chiyero. iyo yakapfava yekuvhara gedhi valve, uye kugadzirisa dambudziko rezvinyoro zvinyoro zvisimbiso zviri kukuvadzwa nekukakavadzana Dambudziko rekuisa chisimbiso chepamusoro, nekuti chisimbiso chekuvhara chevhavha yegedhi chinogona kuchinjwa, kuwedzera zvakanyanya kushandiswa kwevhavha.
Inoshanda mhando yeakapfava chisimbiso gedhi vharafu: dhayamita (p50-p400mm, kudzvanywa 2.5-4.0MPa, dzakasiyana siyana tembiricha zvinwiwa zvisingasviki 200 ℃).
Chisimbiso chakapfava hachigone kusangana nezvinodiwa zvezvimwe zvinhu zvinoparadza, uye chisimbiso chakaoma chinogona kuzvigadzirisa!
Aya marudzi maviri ezvisimbiso anogona kutsigirana.Panyaya yekusimba, chisimbiso chakapfava chinenge chakanaka, asi ikozvino kusimba kwechisimbiso chakaoma kunogonawo kusangana nezvinodiwa zvinoenderana!Kubatsira kwechisimbiso chakapfava kuita kwakanaka kwekuisa chisimbiso, asi chakashata ndechekuti iri nyore kuchembera, kupfeka, uye ine hupenyu hupfupi hwebasa.Chisimbiso chakaoma chine hupenyu hurefu hwesevhisi, asi kuomeswa kwacho kwakashata kupfuura kwechisimbiso chakapfava.
