I-Carbon Steel National Standard Globe Valve

Singumenzi wamavalvu ochwepheshe ophethe izitifiketi ze-ISO, CE kanye ne-API. Samukela ukukhiqizwa okumisiwe okuqinile kanye nezinqubo eziphelele zokuhlola ikhwalithi ukuze siqinisekise ukuthi wonke ama-valve athobela izidingo ezijwayelekile zikazwelonke. Singakwazi ukwenza ngokwezifiso ama-valve ngokwezicelo zakho ze-OEM ne-ODM. Samukela ama-oda emincane yesivivinyo kanye nama-oda amakhulu amaphrojekthi wokwakha ngaphandle kwemikhawulo eqinile yenani. Amavalvu ethu ajwayelekile kazwelonke e-carbon steel globe athunyelwa emazweni amaningi, futhi amakhasimende ezimboni ahlala ekhuluma kakhulu ngawo.

Yiziphi izinto ezisetshenziswayo ukukhiqiza iCarbon Steel National Standard Globe Valves?

Umzimba we-valve uphonswe ku-WCB carbon steel. Inamandla esakhiwo aqinile futhi ingasebenza ngokwethembeka ngaphansi kwezimo zamapayipi okushisa aphezulu. I-valve disc ne-valve stem zenziwe ngensimbi engagqwali ukuvimbela ukugqwala. Indawo yokuxhumana yokuvala i-welded nge-Stellite alloy; lokhu kunqwabelanisa okuqinile kumelana nokugqoka, izinga lokushisa eliphakeme lokukhuhla kanye nokuguguleka okuncane okuvela emithonjeni egelezayo. Ama-gaskets kanye nokupakisha kusebenzisa izinto eziyinhlanganisela ye-graphite ukuze kugcinwe ukuvala okuqinile ngaphansi kokushisa.

Izimfanelo Ezibalulekile

Yiziphi izigaba zokucindezela ezijwayelekile ezisekelwa lawa mavalvu embulunga ajwayelekile?

Wonke ama-valve ethu ahambisana namazinga e-GB, futhi amamaki ethu avamile okucindezela yi-PN16, PN25, PN40 kanye ne-PN64. I-PN16 ne-PN25 ihambisana nokufudumeza okujwayelekile namapayipi amanzi. I-PN40 ne-PN64 zenzelwe amapayipi omusi kanye nowoyela anengcindezi ephezulu asetshenziswa ezimbonini zamandla namakhemikhali. Uma izimo zakho zokusebenza zidinga amazinga okucindezela akhethekile, singakwenzela ngokwezifiso wona.

Izinhlobo ezinjani zemidiya yezinqubo lawa mavalvu eglobu ensimbi ye-carbon steel angaphatha ngokuphepha?

Zilungele isitimu esigcwele izinga lokushisa eliphezulu, uwoyela we-thermal conduction, umoya ocindezelweyo, amanzi okuphakela kubhayela kanye noketshezi lwezimboni olungathathi hlangothi. Asebenza ngokuzinza ngaphansi kwezindawo ezishisa kakhulu lapho ama-valve avala uphawu azohluleka khona. Akunconyelwe ukuba ne-asidi eqinile, i-alkali enamandla noma uketshezi oludlayo olune-chloride ephezulu ngaphandle kokwelashwa kolwelwesi okwengeziwe.

Yiziphi izimboni ezivame ukusebenzisa ama-Carbon Steel National Standard Globe Valves kumapayipi azo?

Afakwe kabanzi ezitshalweni zamandla ashisayo, iziteshi zokushisisa ukushisa okuphakathi, ama-workshops okucubungula i-petrochemical, amasistimu okushisa endwangu kanye namapayipi amanzi azungeza efektri. Lezi zindawo zivame ukudinga ukulungiswa njalo kwevolumu yokugeleza kanye nomfutho wepayipi, okuyinzuzo eyinhloko yama-valve embulunga.

Yimuphi umehluko obalulekile wokusebenza okhona phakathi kwama-valve embulunga nama-valve esango?

Kukhona igebe elisobala ekusetshenzisweni. Amavalvu embulunga enziwa ukuze alawule ukugeleza nokulungisa ukucindezela, futhi ukwakheka kwawo kwangaphakathi kungamisa uketshezi olugeleza luhlehle. Noma ivuleke ngokuphelele, isadala ukumelana nendawo.

Amavalvu esango awowokuvula noma ukuvala ngokuphelele amapayipi, awukwazi ukuwasebenzisa ukulungisa amazinga okugeleza. Uma sezivuleke kakhulu, akwenzekanga lutho ukumelana noketshezi, nokho azikwazi ukuvimbela ukugeleza koketshezi noma igesi okuhlehlayo.
