Yakaoma Seal Globe Valve

Iyo inouya neine flanged yekubatanidza uye inoratidzira simbi-ku-metal sealing kuvaka.Inocheka kuyerera kwemvura zvachose ne zero leakage uye inobvumidza iwe kunyatso gadzirisa kuyerera mukati memapaipi. Mavhezheni eWCB anoshanda zvakanaka kune chiutsi uye zvakajairwa maindasitiri midhiya, nepo mamodheru esimbi asina kusimba anomira kumvura inoparadza. Iri vharafu rinokwana zvakakwana kune petrochemical, magetsi plant, metallurgy uye maindasitiri ekurapa mvura mapurojekiti.

Isu tiri nyanzvi yekugadzira valve ine yakazara ISO, CE uye API certification. Isu tinomhanyisa maseti akazara epamberi CNC machining midziyo uye yakasimba-yakazara-maitiro ekuongorora masisitimu kuti ive nechokwadi chakaenderana kuita kwechigadzirwa kune ese magiredhi. Tsika yeOEM neODM masevhisi anowanikwa aine MOQ inochinjika kuti isangane nemapurojekiti akasiyana zvinodiwa. Yedu yakasimba yakasimba seal seal globe mavharuvhu anoendesa kumisika yepasirese uye kuwana inowirirana mhinduro yakanaka kubva kune vepasirese vanobatana.

Ndeupi musiyano mukuru pakati pevharuvhu yakaoma seal globe uye yakapfava seal globe valve?

Kusiyana nemavharuvhu akapfava eglobhu anovimba nePTFE, rabha kana epurasitiki yekuisa chisimbiso mavharuvhu, yedu yakaoma chisimbiso globe mavharuvhu anotora nyanzvi yesimbi-kune-simbi yakaoma sealing, ine stellite alloy hardfaced pavharuvhu disc uye chigaro. Soft seal modhi inogumira kune tembiricha yekamuri, yakaderera kudzvanywa uye yakachena midhiya. Mukuenzanisa, iyo simbi yakaoma chisimbiso chimiro inozvirumbidza yakakwira-tembiricha kuramba, yakakwirira-kushivirira kushivirira, kupfeka kuramba uye anti-kuvhuvhuta kuita. Izvo hazvipise, kuremara kana kudonha munzvimbo dzakaomarara senge yakakwira-tembiricha yakazara mutsi, yakakwira-kudzvanya maindasitiri gasi uye particle-ine abrasive media, inochengetedza yakavimbika yakavharika kuvharika kwenguva refu inorema-basa indasitiri kushanda.

Ndezvipi zvinhu zvemuviri zvandingasarudza pachigadzirwa ichi, uye ndeipi inokodzera pombi yangu?

Isu tinopa maviri anoshandiswa zvakanyanya kushandiswa evharuvhu zvinhu kuti aenderane akasiyana maindasitiri ekushanda mamiriro: WCB kabhoni simbi, pamwe ne304 uye 316L simbi isina tsvina.

WCB kabhoni simbi inozvirumbidza yakasimba chimiro uye yakakura kumanikidza inotakura huwandu pamutengo wemakwikwi. Inoshanda zvakanaka neasina-corrosive media senge chiutsi cheindasitiri, mvura inotenderera, mweya wakadzvanywa uye oiri yenguva dzose yemumaindasitiri, uye inowanzoshandiswa muzviteshi zvemagetsi, mapaipi ekudziya uye masisitimu epombi efekitori.

Kana pombi yako yakatakura acidic, alkaline kana oxidizing zvinwiwa, tora 304 kana 316L simbi isina tsvina. Aya magiredhi anodzivirira ngura uye kukukurwa kwemakemikari zvakanyanya, zvichiita kuti ive yakakodzera kune zvidyarwa zvemakemikari, mitsetse yemishonga, kurapwa kwemvura yetsvina uye nzvimbo dzekushanda dzekunze.

Hazvina mhosva kuti ndechipi chinhu chemuviri chaunosarudza, ese emukati ekuisa chisimbiso zvikamu zvinouya ne stellite hardfacing overlay. Ese mavharuvhu anowana yakafanana stellite overlay kurapwa, saka imwe neimwe unit inopa yakasimba kupfeka kuramba uye inowirirana yekuisa chisimbiso.

Ko simbi yakaoma seal globe mavharuvhu anonamira pasina chero kuvuza here?

Mavharuvhu mazhinji esimbi akaomarara anonetsekana nekudonha-kudonha nekuda kwekushata kwekugadzira uye kusarongeka kwechokwadi. Nekudaro, zvigadzirwa zvedu zvinotora yakagadziridzwa stellite hardfacing tekinoroji uye yekupedzisira-chaiyo yemanyorero lapping maitiro, kusangana zvizere neAPI yakasimba yekuvhara-kuvharwa zviyero. Yakasiyana nekuisa chisimbiso chesimbi yakapfava chisimbiso mavharuvhu, yedu yekuisa chisimbiso chesimbi inovimba nepamusoro-chaiyo yekukodzera kwemuviri. Isu tinochina chese chikamu nechaiyo CNC midziyo uye tinokuya nzvimbo dzekuisa chisimbiso kakawanda pamaoko. Izvi zvinoita kuti dhisiki yevhavha uye chigaro zvikwane zvakasimba pamwe chete pasina mapundu. Iyo valve inobata zero kuvuza pasi peyakajairwa tembiricha yekushanda uye kudzvanywa, uye chisimbiso chinoramba chakavimbika kunyangwe mushure mezviuru zvekushanda kwakavhurika.

Ndeapi mamiriro ekushanda anoshanda uye zvisingakwanisi kushandiswa kwemavharuvhu akaoma chisimbiso cheglobe?

Iyi yakaoma chisimbiso cheglobe valve yakatevedzana yakanyatso gadzirwa kune yakakwirira-tembiricha, yakakwirira-kumanikidza, abrasive uye yakaoma indasitiri yekushanda mamiriro. Inochinjika kune dzakasiyana siyana dzakaomarara midhiya senge yakakwira-tembiricha yakanyanyisa kupisa, mafuta asina kuchena, gasi rechisikigo, kemikari inoparadza mhinduro, yakanaka particle slurry uye yakasanganiswa gasi reindasitiri. Inoshandiswa zvakanyanya mu petrochemical, kugadzirwa kwemagetsi ekupisa, simbi, migodhi, kurapwa kwemvura mumaindasitiri uye mapurojekiti emagetsi matsva.

Sei mavharuvhu akaomarara egorobhu aine hupenyu hurefu hwesevhisi kupfuura akajairwa mavharuvhu eindasitiri?

Hupenyu hurefu hwesevhisi hunovimbiswa neaviri mabhenefiti ezvigadzirwa uye tekinoroji yekugadzira. Chekutanga, muviri wevharuvhu unotora nzira yekukanda yakabatana ine compact yemukati chimiro, isina maburi ejecha kana porosity, uye yakasimba yakazara kumanikidza-kubereka uye anti-deformation kugona. Kechipiri, iyo yakakosha yekuisa chisimbiso zvikamu zvakafukidzwa nepamusoro-kuoma stellite alloy, ayo anopfeka kuramba uye kusimba kwepamusoro-tembiricha zviri nani kupfuura zvakajairwa simbi isina chisimbiso nzvimbo. Zvichakadaro, iyo yakasarudzika yekuyerera ndima chimiro chevhavhavhavha inodzivirira yakananga yepakati kukanganisa panzvimbo yekuisa chisimbiso, ichideredza abrasion zvinobudirira.

Mavharuvhu akaomeswa seal globe akaomarara kuisa nekuchengetedza?

Kwete. Ese mavharuvhu edu akaomarara eglobe mavharuvhu anotora yakajairika flange yekubatanidza, ichienderana nepasirese API, CE uye ISO mazinga epasi rose, ayo anowirirana neakawanda epasi rose maindasitiri pombi masisitimu uye anotsigira akananga pa-saiti kutsiva uye nekukurumidza kuisirwa. Iyo yakakosha modular dhizaini iri nyore uye inonzwisisika, ine dischable valve stem, disc uye chigaro kuitira nyore kutsiva chikamu. Kugadzirisa kwezuva nezuva kuri nyore kwazvo: kubviswa chete kwepombi kusvibiswa uye kwakakodzera stem lubrication kunodiwa, kuchengetedza nguva uye mushure mekutengesa mutengo.
