Isitywina esinzima seGlobe iValve

Iza kunye noqhagamshelo lwe-flanged kunye ne-metal-to-metal yokwakhiwa kokutywinwa.Inqumla ukuhamba kwamanzi ngokupheleleyo kunye nokuvuza kwe-zero kwaye ikuvumela ukuba ulungelelanise ngokuchanekileyo izinga lokuhamba ngaphakathi kwemibhobho. Iinguqulelo ze-WCB zisebenza kakuhle kumphunga kunye nemithombo yeendaba jikelele yemizi-mveliso, ngelixa iimodeli zentsimbi engatyiwayo zimelana nolwelo oludlekayo. Le valve ingena ngokugqibeleleyo kwi-petrochemical, iplanti yamandla, isinyithi kunye neeprojekthi zokucoca amanzi kwimizi-mveliso.

Singumvelisi wevalvu oqeqeshiweyo onezatifiketi ezipheleleyo ze-ISO, CE kunye ne-API. Siqhuba iiseti ezipheleleyo zezixhobo zomatshini eziphambili zeCNC kunye neenkqubo ezingqongqo zokuhlola umgangatho ogcweleyo ukuze siqinisekise ukusebenza kwemveliso okungaguqukiyo kuwo onke amabanga ezinto eziphathekayo. Iinkonzo eziqhelekileyo ze-OEM kunye ne-ODM ziyafumaneka nge-MOQ ebhetyebhetye ukuhlangabezana neemfuno zeeprojekthi ezahlukeneyo. Iivalvu zethu zeglowubhu eziqinileyo eziqinileyo zithunyelwa kwiimarike zehlabathi kwaye zifumana ingxelo entle engaguqukiyo kumaqabane ehlabathi.

Iimpawu eziphambili

Ngowuphi umahluko ongundoqo phakathi kwevalve yeglowubhu yetywina eqinileyo kunye nevalve yeglowubhu yetywina ethambileyo?

Ngokungafaniyo neevalvu zeglowubhu ezithambileyo ezixhomekeke kwi-PTFE, irabha okanye izinto zokutywina zeplastiki, iivalvu zethu zeglowubhu zeglowubhu eziqinileyo zisebenzisa ukutywina okuqinileyo kwentsimbi ukuya kwentsimbi, ene-stellite alloy eqinile kwidiskhi yesivalo kunye nesitulo. Iimodeli ezithambileyo zokutywina zikhawulelwe kubushushu begumbi, uxinzelelo oluphantsi kunye nemidiya ecocekileyo. Xa kuthelekiswa, ulwakhiwo oluqinileyo lwentsimbi luqhayisa ngokugqwesa ubushushu obuphezulu, ukunyamezela uxinzelelo oluphezulu, ukumelana nokunxiba kunye nokusebenza kokuchasana nokukhukuliseka. Ayiyi kutshisa, ikhubaze okanye ivuze kwindawo enzima efana nobushushu obuphezulu bobushushu obugcweleyo, igesi ephezulu yoxinzelelo lweshishini kunye nemithombo yeendaba erhabaxa enesuntswana, egcina ukuvalwa okuqinileyo okuthembekileyo kokusebenza kwexesha elide elinzima.

Zeziphi izinto zomzimba endingazikhetha kule mveliso, kwaye yeyiphi ehambelana nombhobho wam?

Sinikezela ngezinto ezimbini ezisetyenziswa ngokubanzi kwi-valve ukuze zihambelane neemeko ezahlukeneyo zokusebenza kwamashishini: i-WCB carbon steel, kunye ne-304 kunye ne-316L yensimbi engenasici.

I-WCB carbon steel inesakhiwo esiluqilima kunye noxinzelelo olukhulu oluthwele umthamo ngexabiso elikhuphisanayo. Isebenza kakuhle ngemithombo yeendaba engonakalisiyo efana nomphunga wemizi-mveliso, amanzi ajikelezayo, umoya ocinezelweyo kunye neoyile yemveliso eqhelekileyo, kwaye isetyenziswa ngokuqhelekileyo kwizikhululo zamandla, imibhobho yokufudumeza kunye neenkqubo zombhobho wefektri ngokubanzi.

Ukuba umbhobho wakho uphethe ulwelo oluneasidi, ialkaline okanye i-oxidizing, khetha i304 okanye 316L yentsimbi engatyiwayo. La mabanga axhathisa umhlwa kunye nokhukuliseko lweekhemikhali kakuhle kakhulu, nto leyo eyenza ukuba ifaneleke kakhulu kwizityalo zekhemikhali, imigca yamachiza, ukucocwa kwamanzi amdaka kunye neendawo zokusebenza ezikude nonxweme.

Kungakhathaliseki ukuba yeyiphi imathiriyeli yomzimba oyikhethayo, onke amalungu angaphakathi okutywina aza kunye ne-stellite hardfacing overlay. Zonke iivalvu zifumana unyango olufanayo lokwaleka kwe-stellite, ngoko ke iyunithi nganye ibonelela ngokuxhathisa okuqinileyo kunye neziphumo zokutywinwa ezingaguqukiyo.

Ngaba iivalvu zeglowubhu zesinyithi eziqinileyo ziyatywina ngaphandle kokuvuza?

Uninzi lwezivalo zentsimbi eziqhelekileyo ziyasokola ngokuvuza okuncinci ngenxa yomatshini orhabaxa kunye nokungachaneki kakuhle. Nangona kunjalo, iimveliso zethu zamkela itekhnoloji ephuculweyo yokuqina kwe-stellite kunye nenkqubo ye-ultra-chaneke kakhulu, idibana ngokupheleleyo nemigangatho yokuvala i-API. Ngokwahlukileyo ekutywinweni okulastiki kweevalvu zokutywina ezithambileyo, ukutywinwa kwethu kwentsimbi kuxhomekeke ekufakweni okuphezulu kokuchaneka komzimba. Sisebenza ngomatshini onke amacandelo ngezixhobo ezichanekileyo ze-CNC kwaye sicola iindawo zokutywina izihlandlo ezininzi ngesandla. Oku kuvumela idiskhi yevalve kunye nesitulo silingane ngokuqinileyo ngaphandle kwezithuba. Ivalve ibambe ukuvuza kwe-zero phantsi kobushushu obuqhelekileyo bokusebenza kunye noxinzelelo, kwaye isitywina sihlala sithembekile nasemva kwamawaka emisebenzi evaliweyo.

Zeziphi iimeko zokusebenza ezisebenzayo kunye nokunciphisa ukusetyenziswa kweevalvu zeglowubhu yotywino oluqinileyo?

Olu luhlu lwevalve yeglowubhu yotywino olunzima luphuhliselwe ubushushu obuphezulu, uxinzelelo oluphezulu, olurhabaxa kunye neemeko ezirhabaxa zokusebenza kwimizi-mveliso. Iyaziqhelanisa nemithombo yeendaba entsonkothileyo efana nobushushu obuphezulu bobushushu obuphezulu, i-oyile ekrwada, igesi yendalo, isisombululo esinokutyaka kweekhemikhali, i-particle slurry kunye ne-mixed industry gas. Isetyenziswa kakhulu kwi-petrochemical, ukuveliswa kwamandla obushushu, isinyithi, imigodi, ukucocwa kwamanzi kwimizi-mveliso kunye neeprojekthi zamandla amatsha.

Kutheni iivalvu zeglowubhu yotywino oluqinileyo zinobomi obude benkonzo kuneevalvu eziqhelekileyo zemizi-mveliso?

Ubomi benkonzo ende buqinisekiswa ngeenzuzo ezimbini zezinto kunye neteknoloji yokuvelisa. Okokuqala, umzimba wevalve wamkela inkqubo yokuphosa edibeneyo kunye nolwakhiwo lwangaphakathi oludibeneyo, akukho mingxunya yesanti okanye i-porosity, kunye noxinzelelo olupheleleyo oluthwele kunye nokumelana nokuguqulwa kwamandla. Okwesibini, iindawo zokutywina ezingundoqo zogqunywe ngobunzima obuphezulu be-stellite alloy, obuxhathisa ukunxiba kunye nokuzinza kobushushu obuphezulu bungcono kakhulu kunemigangatho eqhelekileyo yokutywina yentsimbi. Ngeli xesha, ulwakhiwo lokuhamba olukhethekileyo lwevalve yeglowubhu luthintela impembelelo ethe ngqo ephakathi kumphezulu wokutywina, kunciphisa i-abrasion ngempumelelo.

Ngaba iivalvu zeglowubhu eziqinileyo zinzima ukuzifaka kunye nokuzigcina?

Akunjalo. Zonke iivalvu zethu zeglowubhu eziqinileyo zisebenzisa uqhagamshelo lweflange olusemgangathweni, oluthobela i-API, i-CE kunye nemigangatho yezizwe ngezizwe ye-ISO, ehambelana neenkqubo ezininzi zemibhobho yemizi-mveliso yehlabathi kwaye ixhasa ukutshintshwa ngokuthe ngqo kwisiza kunye nofakelo olukhawulezayo. Ulwakhiwo oludityanisiweyo lwemodyuli lulula kwaye lunengqiqo, kunye nesiqu sevalve ekhutshwayo, idiski kunye nesitulo sokutshintsha ngokufanelekileyo. Ukugcinwa kwemihla ngemihla kulula kakhulu: kuphela ukususwa rhoqo kokungcola kwemibhobho kunye nokuthanjiswa okufanelekileyo kwesiqu kuyafuneka, ngokufanelekileyo konga ixesha kunye neendleko zasemva kokuthengisa.
