Yiziphi izindinganiso eziyinhloko nobukhulu?

Senza le Carbon Steel National Standard Flange Globe Valve. Samukela i-GB/T 12235 yokwakhiwa kwamavalvu, i-GB/T 12221 yosayizi bobude obuphelele kanye ne-GB/T 9113 yamaflange ajwayelekile kazwelonke. Sinosayizi abaphelele DN15 kuya ku-DN1200, kanye namabanga okucindezela PN16, PN25, PN40, PN63, PN100 ukuze afane namaphrojekthi amaningi wamapayipi ezimboni.

Izimfanelo Ezibalulekile

Iyini imikhawulo yokusebenza evamile?

Le valve yeglobu yensimbi yensimbi igcina ukusebenza okuphephile okuzinzile ngaphakathi kwezinga lokushisa elisebenzayo elingu -29 ℃ kuya ku-425 ℃. Uma isebenza ngaphansi kwesigaba salo sokucindezela okulinganiselwe, sigcina ukuvala okuqinile okungaguquki ngaphandle kokuvuza, futhi ukwakheka kwevalvu ehlangene kuhlala kunjalo futhi kungaguquki. Ibamba ukusebenza okuzinzile ngesikhathi sokusebenza kwezimboni ubusuku nemini, ukubhekana nemijikelezo yokuvula nokuvala njalo kanye namazinga okushisa okusebenza aguquguqukayo.

Isetshenziselwa ini?

Le valve yakhelwe imisebenzi emibili ebalulekile yasendaweni: ukulawula ukugeleza okuhle kanye nokuhlukaniswa okugcwele kwamapayipi. Isebenza kahle ngamanzi, uwoyela kaphethiloli, igesi yemvelo, isitimu kanye nohlu olubanzi loketshezi olujwayelekile lwenqubo yezimboni. Ngokuvamile ungayithola efakwe kumanethiwekhi amapayipi ezimboni zamakhemikhali, imigqa yokucubungula i-petrochemical, iziteshi zamandla ashisayo, izindawo zokuhlanza amanzi angcolile kanye nemihlangano yokusebenzela yokukhiqiza evamile, elawula ngempumelelo ukulethwa okuphakathi kuzo zonke izinhlobo zezinhlelo zezimboni zokushisa okuphakathi nendawo neziphezulu.

Kungani ukhetha i-carbon steel?

Sisebenzisa i-A216 WCB carbon steel ukuphonsa umzimba we-valve. Le nto inobunzima obuqinile, ukumelana nokucindezela okuhle futhi ingakwazi ukuphatha izinga lokushisa eliphezulu kahle. Ngeke kulimaze kalula ngaphansi kwezimo zokusebenza ezinzima, intengo iyathengeka futhi impilo yesevisi yinde, ngakho-ke ukukhetha okuthandwa kakhulu kwamavalvu embulunga yezimboni ajwayelekile.

Iyiphi imidiya engayiphatha? Noma iyiphi imidiya okufanele uyigweme?

Ifanele amanzi ahlanzekile, umusi, amafutha ashisayo, umoya ocindezelweyo, amafutha alula. Hhayi eye-asidi eqinile/i-alkali ephezulu-corrosion fluid; gwema okuphakathi nezinhlayiya ezinkulu eziqinile ezinwaya indawo yokuvala.

Kungani ukhetha i-valve yembulunga esikhundleni se-valve yesango yomugqa wesitimu?

I-valve ye-Globe isekela ukuvuleka okulungisekayo ukuze kuncishiswe kahle nokulawula ingcindezi. I-valve yesango isebenza kuphela evulekile / evala ngokugcwele ngaphandle kokulawula umsebenzi. I-globe valve ivaleka kakhudlwana ngaphansi kwesitimu esishisayo futhi igwema isando samanzi sepayipi.         

Amaphoyinti angukhiye wokukhwezwa kwe-flange?

Hlanza indawo yokubeka uphawu ye-flange ukuze usule i-welding slag nokugqwala; sebenzisa i-GB graphite/PTFE gasket ehambisanayo; qinisa amabhawodi ngokulinganayo ukuze uvimbele ukuvuza kwe-flange; musa over-torque ukuchoboza gasket.

Ingabe i-globe valve inomkhawulo wendlela yokufaka?

Yebo. Faka ngokulandela umcibisholo wokugeleza kumzimba we-valve (ukugeleza kwemidiya kusuka ngaphansi kwediski kuye phezulu kwediski). Ukuhlehla ukukhweza kubangela ukungavali kahle kahle, ukusebenza kanzima nokubuyela emuva. Isiqu kufanele sihlale siqondile ngesikhathi sokufakwa.
