Yeyiphi imigangatho engundoqo kunye nemilinganiselo?

Senza le Carbon Steel National Standard Flange Globe Valve. Samkela i-GB/T 12235 yoyilo lwevalvu, i-GB/T 12221 yobukhulu bobude obupheleleyo kunye ne-GB/T 9113 yeeflange ezisemgangathweni kazwelonke. Sinobukhulu obupheleleyo be-DN15 ukuya kwi-DN1200, kunye namabakala oxinzelelo lwe-PN16, i-PN25, i-PN40, i-PN63, i-PN100 ukufanisa iiprojekthi ezininzi zemibhobho yezoshishino.

Iimpawu eziphambili

Yeyiphi imida yokusebenza eqhelekileyo?

Le valve yeglowubhu yentsimbi yekhabhoni igcina ukusebenza okuzinzileyo okukhuselekileyo ngaphakathi komgangatho wobushushu osebenzayo we -29 ℃ ukuya kuma-425 ℃. Xa isebenza phantsi kweklasi yoxinzelelo oluhambelanayo, igcina ukutywinwa okuqinileyo okungaguqukiyo ngaphandle kokuvuza, kunye nesakhiwo sevalve esidibeneyo sihlala silungile kwaye singenakuguqulwa. Ibamba ukusebenza okuzinzileyo ngexesha lomsebenzi oqhubekayo we-clock-clock-clock, ukujamelana nokuvula rhoqo kunye nokuvala imijikelo kunye nokuguquguquka kwamaqondo obushushu okusebenza.

Isetyenziselwa ntoni?

Le valve yenzelwe imisebenzi emibini engundoqo kwisiza: ukulawulwa kokuhamba kakuhle kunye nokwahlulwa ngokupheleleyo kwemibhobho. Isebenza ngokugqibeleleyo ngamanzi, ioyile yamafutha, igesi yendalo, umphunga kunye noluhlu olubanzi lwenkqubo yolwelo oluqhelekileyo lweshishini. Ungayifumana ngokuqhelekileyo ifakwe kuthungelwano lwemibhobho yeefektri zekhemikhali, imigca yokulungisa i-petrochemical, izikhululo zamandla ashushu, amaziko okucoca amanzi amdaka kunye neendibano zocweyo zokwenziwa ngokubanzi, ukulawula ngokufanelekileyo unikezelo oluphakathi kuzo zonke iintlobo zeenkqubo zoshishino zobushushu obuphakathi kunye nobushushu obuphezulu.

Kutheni ukhetha i-carbon steel?

Sisebenzisa i-A216 WCB carbon steel ukuphosa umzimba wevalvu. Esi sixhobo sinobunzima obuqinileyo, ukuchasana kakuhle koxinzelelo kwaye kunokusingatha ukushisa okuphezulu kakuhle. Ayizukonakala ngokulula phantsi kweemeko zokusebenza ezinzima, ixabiso liyafikeleleka kwaye ubomi benkonzo bubude, ngoko lolona khetho ludumileyo kwiivalvu zeglowubhu zemizi-mveliso.

Yeyiphi imidiya enokuyiphatha? Nayiphi na imidiya onokuyiphepha?

Ifanele amanzi acocekileyo, umphunga, ioli eshushu, umoya ocinezelweyo, ioli ekhanyayo. Hayi for acid eyomeleleyo/alkali high-corrosion fluid; Kuthintele okuphakathi ngamasuntswana aqinileyo aqinileyo akrwela umphezulu wokutywina.

Kutheni ukhetha ivalve yeglowubhu endaweni yevalve yesango yomgca womphunga?

Ivalve yeglowubhu ixhasa ukuvuleka okuhlengahlengiswayo ukuze kuthotywe ngokuchanekileyo kunye nolawulo loxinzelelo. Ivalve yesango isebenza kuphela ivuleke ngokupheleleyo/ivale ngokupheleleyo ngaphandle kokulawula ukusebenza. Ivalve yeglowubhu ivalwe ngokungqongqo phantsi komphunga oshushu kwaye inqanda isando samanzi semibhobho.         

Amanqaku aphambili okufakwa kweflange?

Coca indawo yokutywina yeflange ukucima i-welding slag kunye nomhlwa; sebenzisa i-GB ehambelanayo yegraphite/PTFE gasket; qinisa iibholithi ngokulinganayo ukuthintela ukuvuza kweflange; musa ukugqithisa i-torque ukutyumza i-gasket.

Ngaba ivalve yeglowubhu inomda wokufakela umkhombandlela?

Ewe. Faka ngokulandela utolo lokuhamba kumzimba wevalvu (ukuhamba kwemidiya ukusuka phantsi kwediski ukuya ngaphezulu kwediski). Ukubuyisela umva ukunyuswa kubangela ukutywinwa kakubi, ukusebenza nzima kunye nokubuyela umva. Isiqu kufuneka sihlale sithe nkqo ngexesha lofakelo.
