Mavharuvhu eshavishavi anoshanda sei?

Butterfly valveimhando yevharuvhu inoshandisa dhisiki yekuvhura nekuvhara chikamu kudzorera nezve 90 ° kuvhura, kuvhara kana kugadzirisa kuyerera kwepakati. Butterfly valve haina kungoita chimiro chakareruka, saizi diki, huremu huremu, kuderera kwekushandisa, diki yekuisa saizi, diki yekutyaira torque, iri nyore uye nekukurumidza kushanda, asiwo ine yakanaka yekuyerera mutemo basa uye kuvhara chisimbiso maitiro, uye ndeimwe yekukurumidza kukura. mhando dzevharuvhu mumakore gumi apfuura. Butterfly mavharuvhu anoshandiswa zvakanyanya. Izvo zvakasiyana-siyana uye huwandu hwekushandiswa kwayo hunoramba huchiwedzera, uye huchikura kusvika pakupisa kwepamusoro, kudzvinyirira kukuru, dhayamita yakakura, kusungirirwa kwepamusoro, hupenyu hurefu, maitiro ekugadzirisa zvakanaka, uye kushanda kwevhavha imwe chete. Kuvimbika kwayo uye zvimwe zviratidzo zvekuita zvasvika padanho repamusoro.

Nekushandiswa kwemakemikari anodzivirira synthetic rubber kubutterfly valves, kuita kwebutterfly valvesyakavandudzwa. Nekuti rabha rekugadzira rine hunhu hwekuramba corrosion, kushomeka kwekukura, kugadzikana kwedimensional, kugadzikana kwakanaka, kuumba nyore, kudhura kwakaderera, nezvimwewo, rabha rekugadzira rine zvinhu zvakasiyana rinogona kusarudzwa zvinoenderana nezvinodiwa zvakasiyana zvekushandisa kusangana nemamiriro ekushanda.butterfly valves.

Nekuti polytetrafluoroethylene (PTFE) ine yakasimba corrosion resistance, yakagadzikana kuita, isiri nyore kuchembera, yakaderera coefficient of friction, nyore kugadzira, dimensional kugadzikana, uye inogona kuvandudza yayo yakazara hupfumi nekuzadza nekuwedzera zvinhu zvakakodzera, iyo butterfly valve yekuisa chisimbiso nezvinhu zviri nani. simba uye yakaderera friction coefficient inogona kuwanikwa, uye izvo zvinogumira zvekugadzira rabha zvinokundwa, saka iyo polymer polymeric zvinhu zvinomiririrwa nePTFE uye kuzadza kwayo kwakagadziridzwa zvinhu zvakashandiswa zvakanyanya muvhavhavhavhavha, kuitira kuti mashandiro evhavhavhavhavhavha ave. yakawedzera kuvandudzika.Butterfly mavharuvhunehupamhi hwakawanda hwekushisa uye kumanikidzwa, yakavimbika yekuisa chisimbiso kuita uye hupenyu hwesevhisi hurefu hwakagadzirwa.

Kuti isangane nezvinodiwa mumaindasitiri mafomu akadai tembiricha yakakwira uye yakaderera, kukukurwa kwakasimba, uye hupenyu hurefu, simbi chisimbiso butterfly mavharuvhu akagadzirwa zvikuru. Nekushandiswa kwekudzivirira kwekushisa kwepamusoro, kupikisa kwekushisa kwakadzika, kupikisa kwakasimba kwekuora, kupikisa kwakasimba kwekukurwa kwevhu, uye simba rakakwirira-alloy zvinhu mumavharuvhu eshavishavi, simbi yakavharwa mavharuvhu e butterfly ave achishandiswa zvakanyanya muminda yemaindasitiri senge tembiricha yakakwira uye yakaderera, kukukurwa kwakasimba. , uye upenyu hurefu, uye butterfly mavharuvhu ane dhayamita yakakura (9 ~ 750mm), high pressure (42.0MPa) uye yakafara tembiricha siyana (-196 ~ 606 ° C) akaonekwa, saka kuti tekinoroji butterfly mavharuvhu asvika padanho idzva. .

Kana vharuvhu yeshavishavi yakazarurwa zvizere, ine diki yekuyerera inopikisa. Kana kuvhura kunenge kuri pakati pe 15 ° ~ 70 °, inogona kushandiswa pakugadzirisa kuyerera kwekuyerera, saka kushandiswa kwevhavhavhavhavhavha kunowanzoitika mumunda wekugadzirisa dhayamita hombe.

Nekuda kwekufamba kunopusika kweshavishavivhavhavhavhavhavhavharupu,mavharuvhu mazhinji eshavishavi anogona kushandiswa panhau dzine masimbi akaturikwa. Zvichienderana nekusimba kwechisimbiso, inogonawo kushandiswa kune hupfu uye granular media.

Butterfly mavharuvhu akakodzera kuyerera kwemutemo. Nemhaka yokuti kupererwa kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha. butterfly plate kutakura kumanikidza kwepombi yepakati kana yakavharwa inofanirawo kutariswa. Uye zvakare, izvo zvinogumira tembiricha yekushanda iyo iyo elastomeric chigaro zvinhu inogona kuiswa pane yakakwirira tembiricha inofanirawo kuverengerwa.

The butterfly valve ine diki rekuvaka kureba uye kureba kwese, kukurumidza kuvhura uye kuvhara kumhanya, uye yakanaka yekudzora hunhu. Nheyo yemaitiro emavharuvhu e butterfly inonyanya kukodzera kugadzira mavharuvhu makuru. Kana vhavhavhavhavha inodiwa kuti ishandiswe kudzora kuyerera kwemvura, zvakakosha kuti usarudze hukuru hwakakodzera uye rudzi rwevhavhavhavhavha kuitira kuti ishande zvakanaka uye zvinobudirira.

Kazhinji, mukuputika, kutonga kwekutonga uye dhaka repakati, kureba kwechimiro kupfupi, kuvhura uye kuvhara kumhanya kunokurumidza, uye kuderedzwa kwepasi-kubvisa (kusiyana kwepakati) kunodiwa, uye butterfly valve inokurudzirwa. Butterfly mavharuvhu anogona kushandiswa kana paine maviri-nzvimbo kugadzirisa, yakaderedzwa dhayamita chiteshi, yakaderera ruzha, cavitation uye vaporization, shoma shoma inobuda mumhepo, uye abrasive media. Pasi pemamiriro akakosha ekushanda, throttling kugadziridzwa, kana kuvharirwa kwakasimba, kupfeka kwakakomba, tembiricha yakaderera (cryogenic) uye mamwe mamiriro ekushanda.
