Isiqu esinganyukiyo kunye neSithi esiKhuphukayo seManuwali yeGlobhu ivelufa

Singumenzi wevalvu oqeqeshiweyo obambe iziqinisekiso ze-ISO kunye ne-API. Sinezixhobo eziphambili zemveliso kunye neseti epheleleyo yeenkqubo zokulawula umgangatho. Sikwamkele iiodolo ze-OEM kunye ne-ODM, kunye nobungakanani obuncinci bokuodola. Iivalvu zethu zeglowubhu ezomeleleyo zithunyelwa kwiimarike zehlabathi kwaye zifumana ingxelo entle engaguqukiyo kuwo onke amahlakani.

Iimpawu eziphambili

Ngowuphi umahluko ophambili phakathi kweevalvu zeGlobhu zeSithi esiNgakhuphukiyo kunye neSithi esinyukayo?

Kuhlobo lwesiqu esinyukayo, isiqu sevalve sinyuka sinyuka kunye nediski xa uvula okanye uvala. Unokugweba ngokuthe ngqo imeko evulekileyo / evaliweyo ngokubona ukuba isiqu siphuma kude kangakanani, nto leyo eyenza ukuba uhlolo lwemihla ngemihla lube lula kakhulu.

Kuyilo lwesiqu olunganyukiyo, isikhondo sijikeleza kuphela endaweni ngaphandle kokwandisa ngaphandle. Umsonto wangaphakathi uqhuba idiski ukuba ihambe. Kuthatha indawo ethe nkqo encinci kakhulu, ilungele imibhobho efakwe kwimingxuma emxinwa, iikhabhathi ezingaphantsi komhlaba okanye iindawo ezinobude obulinganiselweyo.

Zeziphi izixhobo ozinikezelayo kwezi ntlobo zimbini zeevalvu zeglowubhu zezandla?

Sinikezela nge-carbon steel WCB kunye ne-stainless steel 304 / 316L iinketho. I-WCB ifanele umphunga, i-oyile kunye nolwelo oluqhelekileyo lwamashishini olunemfuno ephezulu yobushushu. Iinguqulelo zentsimbi engenastainless zisebenza ngcono xa zithelekiswa namanzi olwandle, amanzi anetyuwa kunye neekhemikhali ezibuthathaka ezitshabalalisayo. Zonke ii-castings zihamba kuvavanyo olungqongqo lwemathiriyeli phambi komatshini.

Ingaba zombini iivalve zeGlobhu ye-Stem ezingakhuphukiyo kunye ne-Rising Stem Manual zilawula ukuhamba ngaphandle kokuvalwa?

Ewe, zombini uyilo luxhasa uhlengahlengiso oluchanekileyo lokuhamba kunye nokunqunyulwa kombhobho opheleleyo. Ulwakhiwo lwazo lwetrim yangaphakathi ikuvumela ukuba uvule ivalve ngokuyinxenye ukuzinzisa ukuhamba okuphakathi kunye noxinzelelo lombhobho, hayi nje ukuvuleka ngokupheleleyo okanye ukuvala ngokupheleleyo njengeevalvu zebhola. Zisetyenziswa ngokubanzi kwimigca efuna ulawulo lokuhamba rhoqo.

Loluphi uxinzelelo kunye nobushushu ezinokuphathwa zezi zivalo zeglowubhu zezandla?

Amanqanaba oxinzelelo asemgangathweni agubungela i-PN16, i-PN25, i-PN40 kunye neKlasi ye-150, i-300. Ubushushu bokusebenza buvela kwi--29 ° C ukuya kwi-425 ° C. Izinto ze-WCB zisebenza kakuhle kwiinkqubo zokushisa eziphezulu zokushisa, ngelixa insimbi engenasici igcina ukusebenza okuzinzile kumajelo aphantsi obushushu.

Yeyiphi imigangatho yeflange ekhoyo?

Sivelisa iiflange ezithobela imigangatho ye-ANSI, i-DIN, i-GB kunye ne-JIS. Ubuso obunyusiweyo be-RF kunye nemigangatho ye-FF ethe tyaba yokutywina yomibini ayinyanzelekanga. Ukuba indawo yakho ineemfuno ezikhethekileyo zomngxuma we-bolt, sinokuhlengahlengisa ubungakanani be-flange yokomba ngokwemizobo yakho.

Loluphi ukhetho lokutywina olunikezelayo kwimidiya eyahlukeneyo yokusebenza?

Iintlobo ezintathu zokutywinwa eziqhelekileyo zokukhethwa:

Itywina elithambileyo le-PTFE: iqanda elivuzayo, lilungele ulwelo olunobushushu obuqhelekileyo;

Itywina lokupakisha i-graphite: ukumelana nobushushu obuphezulu, eyona nto ifanelekileyo kwimibhobho yomphunga;

Metal hard seal: Ukunxitywa kwentsimbi, kusetyenziselwa ulwelo olunoxinzelelo oluphezulu olunobumdaka obuncinci obuqinileyo.

Zeziphi iisayizi ezisesitokhweni, kwaye unokwenza ubungakanani besiko?

Ubungakanani obuqhelekileyo be-DN15 ukuya kwi-DN300 bugcinwe kwisitokhwe ukuze kuhanjiswe ngokukhawuleza. Ubukhulu obungaphezulu kwe-DN300 okanye i-non-standard bore, siyayamkela imveliso yesiko elipheleleyo. Yonke imilinganiselo iya kujongwa kabini phambi kokupakishwa nokuthunyelwa.

Zeziphi iimeko zemizi-mveliso ezihambelana nezi zivalo zeGlobhu zeSithi ezinganyukiyo kunye neSithi esinyukayo?

Zisetyenziswa kakhulu kwizikhululo zamandla, iifektri zekhemikhali, iinkqubo zokufudumeza umphunga, amaziko okucoca amanzi kunye nemibhobho exhasa i-oyile-gesi. Iindidi zezikhondo ezinyukayo zikhethwa kwimibhobho engaphezulu komhlaba enofikelelo olulula ekuyihloleni. Iinguqulelo ze-stem ezingavukiyo zithandwa kakhulu kwimibhobho engcwatywe phantsi komhlaba kunye namagumbi ezixhobo ezixineneyo.

Ngaba uyayixhasa i-OEM kunye nomsebenzi owenzelwa umntu?

Sithatha iiodolo ze-OEM kunye ne-ODM eziguquguqukayo ukuze zihambelane neemfuno zeprojekthi yakho. Singakrola uphawu lwebrand yakho ngelaser kwimizimba yevalvu, sihlengahlengise uxinzelelo kunye namazinga obushushu, sithathe indawo yezixhobo zokutywina zolwelo olukhethekileyo, siyilwe ngokutsha iimilo zamavili esandla, kwaye silungise amalungu angaphakathi njengoko ucela. Upakisho oluqhelekileyo lokuthumela ngaphandle lukwakhona.

Kuthekani ngexesha lakho lokuhambisa?

Iivalve eziqhelekileyo ezivela kwisitokhwe zinokuthunyelwa ngaphakathi kweentsuku ezi-3-7 zokusebenza kwiiprojekthi eziphuthumayo. Iivalvu ezenziwe ngokwezifiso kunye nee-odolo zesambuku ezinkulu zithatha malunga ne-30 ukuya kwiintsuku zokusebenza ezingama-40. Siya kuqinisekisa ishedyuli emiselweyo yokuhanjiswa kunye nawe ngaphambi kokubeka umyalelo ngokusekelwe kubuninzi bakho kunye nesicwangciso sokuvelisa imveliso.

Kutheni ukhetha ivalve yeglowubhu ngaphezulu kwevalve yebhola ukuze ulawule ukuhamba?

Iivalvu zebhola zisebenza kakuhle kuphela phantsi kwemeko evuleke ngokupheleleyo okanye evalwe ngokupheleleyo; ukuvuleka ngokuyinxenye kuya kukhokelela kukhukuliseko olumandla kwimigangatho yokutywinwa. Iivalve zeglowubhu zineepaseji ezigophe ngokukodwa zangaphakathi, ezinciphisa iimpembelelo zetywina ngexesha lokutswina. Babambe ukusebenza okuzinzile kwixesha elide lomsebenzi wokulungelelanisa ukuhamba rhoqo.
