Fluorine-linedbutterfly valveimhando yevharuvhu yekugadzira inowanzoshandiswa muasidhi uye alkali uye zvimwe zvinoparadza media.Yakave yakashandiswa zvakanyanya mu petroleum, makemikari, mishonga, simbi, simba remagetsi uye mamwe maindasitiri.Pamusana pekuoma kwemaitiro ayo ekugadzirisa uye kuoma kwezvinhu zvekugadzira Diversity, kazhinji vashandisi havazivi kuti vangatanga sei kusarudza, chinyorwa ichi chichasuma nzira yekusarudza fluorine-lined butterfly valve.
1. Fluorine-lined butterfly valve ivhavha yepurasitiki yakaputirwa pamusoro pesimbi yakakandwa kana muviri wevhavha yesimbi uye boka revhavha re disc rinosangana nemvura.Chinangwa chekuora.Sezvo plastiki iri kusangana nepakati, kuoma kwayo kwakashata, uye iyo inoshandiswa haifaniri kunge iine zvimedu zvakaoma, makristasi, tsvina, nezvimwewo, kuitira kudzivirira vharafu kubva pakupfeka core yevhavha, iyo fluorine-lined layer. yechigaro chevharuvhu kana fluorine layer panguva yekuvhura nekuvhara kwevhavha.Fluorine inoyerera.Kune iyo yepakati neyakaoma particles, makristasi uye kusvibiswa, pakusarudza, yevhavha yepakati uye chigaro chevharuvhu chinogona kusarudzwa kubva kune corrosion-resistant alloys, senge INCONEL, MONEL, Hastelloy, nezvimwe.
2. Kupisa kwepakati inoshandiswa ne fluorine-lined butterfly valve: iyo fluorine plastiki inoshandiswa iF46 (FEP), uye tembiricha yepakati inoshandiswa haigoni kudarika 150 ° C (kupisa kwepakati kunogona kusvika 150 ° C mukati. nguva pfupi, uye kutonhora kunofanira kudzorwa mukati me120 ° C kwenguva yakareba) Kana zvisina kudaro, F46 lining yezvikamu zvevhavha iri nyore kupfava uye kukanganisa, zvichiita kuti valve ivhare zvisingafadzi uye kuputika kukuru.Kana tembiricha yepakati inoshandiswa iri pasi pe180 ℃ kwenguva pfupi uye pasi pe150 ℃ kwenguva yakareba, imwe fluoroplastic inogona kushandiswa.
-PFA, asi PFA yakavharwa nefluoroplastics inodhura kupfuura F46 yakarongwa.
3. Musiyano wekumanikidza uye kudzvinyirira kunofanira kudzorwa mukati meiyo inobvumirwa chiyero.Kana kudzvinyirirwa uye kusiyana kwakasiyana kwakakura zvakanyanya, zviri nyore kukonzera kukanganisa kwechisimbiso panguva yekuzarura nekuvhara kwevhavha, izvo zvichakanganisa kushanda kwekuvhara kwevhavha.
4. Iyo yakawanda masitaera yeindasitiri inoodza media kazhinji haisi mhando imwechete yeasidhi, alkali, uye munyu.Izvi zvinoita kuti zviome kusarudza yakakodzera lining material, iyo inoda kusarudzwa kwakazara kwema parameter senge yemvura yekumisikidzwa reshiyo, concentration, yepakati tembiricha, particle size, uye kuyerera kwepakati.
5. Iyo fluorine-lined butterfly valve inofanira kusarudzwa zvakarurama maererano nehuwandu hunodiwa hwekuyerera (Cv value).Iko CV kukosha kwefluorine-lined butterfly valve idiki zvishoma pane yeyakajairika wafer butterfly valve uye flange butterfly valve.Paunenge uchisarudza, dhigirii uye dhigirii yekuvhura yevhavhavhavhavhavhavha yefluorine-lined butterfly inofanira kuverengwa maererano neinodiwa kuyerera (Cv value) uye mamwe maitiro emagetsi.Kana iyo dhayamita yevhavha yakasarudzwa yakakura zvikuru, ichaita kuti valve ivhure kwenguva yakareba.Kushanda pasi pemamiriro madiki, pamwe nekudzvanywa kwepakati, kuchaita nyore nyore kuti vheji yepakati uye tsvimbo ishandiswe nepakati kuti iite kuti vharafu rizungunuke.Iyo valve core rod ichatoputswa pasi pesimba repakati kwenguva yakareba.Paunosarudza marudzi akasiyana-siyana e-fluorine-lined valves, vashandisi vanofanira kunzwisisa uye kubata maitiro ehutano hwekushandisa zvakanyanya sezvinobvira, kuitira kuti vagone kusarudzwa uye kushandiswa zvakanaka, uye hupenyu hwebasa revhavha hunogona kuvandudzwa.Muchiitiko chekupfuura chiyero cheiyo tekinoroji mamiriro ekushandiswa, inofanirwa kupihwa mugadziri, kutaurirana pamwe chete, uye kugashira nhanho dzinoenderana kugadzirisa.6. Dzivisa dzvinyiriro isina kunaka.Iyo fluorine-lined valve inofanira kudzivisa kushandiswa kwesimba rakaipa mupombi.Kana pane kudzvinyirirwa kwakashata, iyo fluorine-lined layer mukati memukati wevhavha ichave yakasvetwa kunze (yakaputika) uye yakavharwa, izvo zvichaita kuti valve ivhure uye ivhare kusashanda.
