Nzira yekusarudza yakakodzera butterfly valve?

Plastiki butterfly valve chinhu chakajairika chekudzora mvura, chinoshandiswa zvakanyanya muindasitiri, kuvaka uye kurima. Kune UPVC CPVC PPH PVDF PPH zvinhu butterfly valve. Iyo mubato revheti butterfly size inosanganisira DN50, DN65 DN80, DN100, DN 200, The worm geared butterfly valve inosanganisira DN50 ~DN300. Iyo ine zvakanakira chimiro chakareruka, nyore kushanda uye corrosion kuramba, saka inofarirwa zvakanyanya nevashandisi. Zvisinei, kana kutenga epurasitiki butterfly vharafu, tinofanira kufunga zvimwe zvinhu zvinokosha. Ichi chinyorwa chinokupa iwe yepurasitiki butterfly valve yekusarudza gwara kuti ikubatsire kusarudza chaiyo chigadzirwa.

1, Chemical kugarisana:

Sarudza chaiwo makemikari kana zvinwiwa izvo valve ichave yakaratidzwa. Sarudza zvinhu zvepurasitiki zvemuviri wevharuvhu uye zvikamu zvinopokana zvakanyanya nekuora kwemakemikari. Mapurasitiki akasiyana ane madhigirii akasiyana ekupikisa makemikari akasiyana, saka kuenzanisa zvinhu kune chaiwo makemikari zvimiro zvakakosha.

2, Sarudza zvinhu zvakakodzera:

Plastic butterfly valves yakagadzirwa nemhando dzakasiyana-siyana dzezvinhu, zvinowanzowanikwa muPVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride), PP (polypropylene), PVDF (polyvinylidene fluoride) uye PTFE (polytetrafluoroethylene). maitiro akasiyana ekuita, saka iwe unofanirwa kusarudza iyo yakakodzera zvinhu zvinoenderana nezvinodiwa chaizvo. Kazhinji kutaura, polypropylene inokodzera general medium, PVC yakakodzera kune isina kusimba asidhi uye alkali svikiro, PTFE inokodzera yakasimba asidhi uye alkali svikiro, uye FRP inokodzera kupisa kwepakati.

pakusarudza PVC, CPVC, PP kana PVDF butterfly mavharuvhu emhando dzakasiyana dzemakemikari ekushandisa, zvakakosha kufunga nezve kuenderana kwemakemikari echinhu chimwe nechimwe. Aya anotevera ndiwo nhungamiro yakajairika yekuenderana kwezvinhu izvi neakasiyana makemikari:

PVC (polyvinyl chloride) butterfly valve:

Inokodzera kurapa mvura, asidhi (dilute), alkali uye munyu mhinduro.

Hazvikurudzirwe kushandiswa nemaasidhi akasimba, ketoni, esters uye anonhuwirira kana chlorinated hydrocarbons.

CPVC (chlorinated polyvinyl chloride) butterfly valve:

Inoshingirira kune huwandu hwakakura hwemakemikari kupfuura PVC, kusanganisira inopisa inopisa zvinwiwa, munyu, uye akawanda maasidhi nemaalkali.

Hazvikurudzirwi kushandiswa ne polar solvents, aromatic hydrocarbons uye chlorinated hydrocarbons.

PP (polypropylene) butterfly valve:

Inopikisa zvakasiyana-siyana zveasidhi, alkalis uye organic solvents.

Hazvikurudzirwi kushandiswa neakasimba oxidizing acids, chlorinated hydrocarbons, anonhuwirira uye halogenated hydrocarbons.

PVDF (polyvinylidene fluoride) butterfly valve:

Inopikisa zvakanyanya kumhando dzakasiyana dzemakemikari anoodza, anosanganisira akasimba acids, mabhesi uye halogenated solvents.

Inokodzera kubata makemikari anoparadza uye maapplication ekuchena kwepamusoro.

Iva nechokwadi chekutarisa kemikari inoenderana machati uye chaiwo data data mapepa kuti uve nechokwadi chekusarudzwa kwakaringana kwePVC, CPVC, PP kana PVDF butterfly mavharuvhu ekushandisa kwakasiyana makemikari. Pamusoro pezvo, funga tembiricha uye kudzvanywa mamiriro pamwe neanodzora uye indasitiri zviyero paunenge uchiita sarudzo yako.

3. Teerera kune chimiro chemuviri wevharuvhu:

Plastic butterfly valve body chimiro zvakare chimwe chezvinhu zvinofanirwa kutariswa kana uchitenga. Yakajairika vharafu muviri chimiro ine flange mhando, threaded mhando uye welded mhando. Flanged valve body inokodzera dhayamita hombe uye nguva dzekumanikidza kwakanyanya, yakarukwa yevhavha muviri inokodzera diki dhayamita uye yakaderera kumanikidzwa nguva, welded valve body inokodzera kupisa kwakanyanya uye nguva dzekumanikidza. Saka, iwe unofanirwa kusarudza iyo yakakodzera valve body structure maererano nemamiriro ezvinhu chaiwo paunenge uchitenga.

4. Teerera kune chigaro zvinhu:

Chigaro chevhavha chikamu chakakosha chepurasitiki butterfly valve, iyo inobata zvakananga kushanda kwekuvhara kwevhavha. Zvakajairika vharafu zvigaro zvinosanganisira EPDM (ethylene propylene diene monomer), Buna-N (nitrile rabha), fluoroelastomer (FKM, FPM, VITON), PTFE uye polyurethane. FKM、FPM、VITON ine yakanaka ngura uye abrasion kuramba, PTFE ine yakanakisa ngura uye yakakwirira tembiricha kuramba, uye polyurethane ane yakanaka abrasion uye mafuta kuramba. .

Zvinhu izvi zvakasarudzwa nekuda kwekugona kwavo kupa chisimbiso chakasimba, kupfeka kuramba, uye kuenderana nemhando dzakasiyana dzemvura uye tembiricha. Izvo zvinhu zvinoshandiswa zvepurasitiki butterfly valve zvigaro zvinoenderana nekushandiswa, rudzi rwemvura iri kudzorwa, uye mamiriro ekushanda.

Paunenge uchitenga, unofanirwa kusarudza yakakodzera chigaro chevharuvhu zvinoenderana nehunhu hwepakati

00001.

5, Kudzvinyirira uye Tembiricha Ratings:

Sarudza mavharuvhu anogona kubata kumanikidzwa kwekushanda uye mamiriro ekushisa mukati mehurongwa kuti ave nechokwadi chekushanda kwakachengeteka uye kwakavimbika.

Plastic raw material zita uye tembiricha inoshanda:

6, Saizi uye Kuyerera:

Sarudza saizi yevharuvhu uye kuyerera kunoenderana nezvinodiwa system kuti uwane yaunoda kuyerera kudzora.

7. Funga nezvemaitiro ekushanda:

Plastic butterfly mavharuvhu anoshandiswa nemaoko, magetsi uye pneumatically. Manual operation iri nyore, yakaderera mutengo, yakakodzera kune madiki masisitimu; kushanda kwemagetsi kuri nyore, kururamisa kwakanyanya, kwakakodzera masisitimu makuru; pneumatic operation inokurumidza, yakakwirira dhigirii ye automation, inokodzera masisitimu anoda kugara achichinja. Nokudaro, mukutenga kudiwa kwekusarudza nzira yakakodzera yekushanda maererano nezvinodiwa chaizvo.

8. Teerera kumazinga evharuvhu uye chitupa:

Mukutenga epurasitiki butterfly mavharuvhu, iwe zvakare unofanirwa kutarisisa kuti vharafu inosangana neakakodzera zviyero uye zvitupa zvinodiwa. Zvakajairika zviyero uye zvitupa ISO, CE, API uye zvichingodaro. Kusarudza zvigadzirwa zvinozadzisa zviyero uye zvitupa zvinodikanwa zvinogona kuve nechokwadi chemhando uye kuchengetedzeka kwechigadzirwa.

Nekunyatsofunga nezvezvinhu izvi, unogona kusarudza epurasitiki butterfly valve yakakodzera kubata makemikari akasiyana, kuve nechokwadi chekuchengetedza, kuvimbika uye hupenyu hurefu muchikumbiro chako.
