IsiRashiya ivelufa yesango yeflange esemgangathweni

Umgaqo wokuSebenza we-Russian Standard Rising Stem Flanged Gate Valves

Ivalve yesango ehlala ixesha elide kwaye ethembekileyo isebenza kumgaqo wokujikeleza isikhondo sevalvu ukuqhuba intshukumo yesango. I-handwheel ijikeleza i-valve stem endaweni, kwaye intambo ye-trapezoidal ezantsi kwesiqu idibanisa ne-nut ngaphakathi kwesango, iguqule ukunyakaza okujikelezayo kwintshukumo yomgca wesango. Ukujikelezisa ivili lesandla ngokwewotshi kwehlisa isango, licinezele kwisitulo sevalvu ukufikelela isitywina; ukujikeleza nge-counterclockwise kuphakamisa isango, ukulikhupha kwindlela yokuhamba kunye nokuvula ivalve. Isiqu sevalve asize siphakame okanye siwe, sijikeleza kuphela, okukhokelela kubude obuncinci bokufakela. Umzimba oyintloko wenziwa yi-WCB, SUS304 (CF8), okanye i-SUS316L (CF3M), iqinisekisa ukutywinwa okuthembekileyo kunye nokufaneleka kokulawula ukuvala kwiinkqubo zemibhobho eziqhelekileyo zaseRashiya.

Iiparamitha zeMveliso

Ihlala ixesha elide kwaye ihlala ixesha elide

I-Shenchi Russian Standard Exposed Stem Flanged Gate Valves ibonisa zonke-metal amacandelo angaphakathi, kunye nezinto zangaphakathi zetsimbi ezihambelana nomzimba, ukuphelisa amanqaku abuthathaka. I-WCB cast iron valve body iqhayisa amandla aphezulu kunye nokumelana nempembelelo; izinto zensimbi ezingenasici ziyakwazi ukumelana ne-corrosion, zifanelekile kwiindawo ezifumileyo kunye ne-corrosion. Umsonto wetrapezoidal wesiqu sevalve uchanekileyo-oomatshini bokusebenza kakuhle kunye nokunxiba okuncinci. Umphezulu wokutywina ugqitywe nge-alloy yobhedu okanye insimbi engenasici, enikezela ukuchasana nokukhukuliseka kunye nobomi obude benkonzo. Ixabiso eliphantsi alilingani nomgangatho ophantsi; I-Shenchi inikezela ngokuthe ngqo kwifektri, ukuphelisa abalamleli kunye nokubonelela ngexabiso elibalaseleyo.

Imeko yeSicelo 1: Imibhobho engaphantsi komhlaba iShenchi iMigangatho yaseRashiya eBenzisiweyo yeSithi esiFlanged iSango iiValufa zibonakalisa uyilo olufihliweyo lwesiqu, esinesiqu sevalvu enganyukiyo okanye ewe, nto leyo ekhokelela kubude obuphantsi bofakelo, nto leyo ebenza ukuba bafaneleke ngokukodwa iindawo ezixineneyo ezifana nemigodi yevalve kunye neerakhi zemibhobho engaphantsi komhlaba. Uqhagamshelo lwe-flange lubonelela ngesitywina esithembekileyo, kunye nomgangatho woxinzelelo lwe-PN16, olufanelekileyo kwimibhobho kamasipala efana nokubonelela ngamanzi, ukufudumeza kunye nogutyulo. Ukusebenza okuphezulu komgangatho waseRussia oveziweyo we-Stem Flanged Gate Valves, ene-stem engabonakaliyo, ayithinteki kakhulu kwi-corrosion evela kumswakama womhlaba kunye nokungcola, ukugcina ukusebenza kakuhle nangemva kokusetyenziswa kwexesha elide phantsi komhlaba.

Usetyenziso lweSicelo sesi-2: Imibhobho yoShishino

I-Shenchi Russian Standard Rising Stem Flanged Gate Valves ifanelekile kumashishini afana nepetroleum, imichiza, amandla, kunye nesinyithi. Imidiya ibandakanya amanzi, umoya, igesi, i-petroleum, kunye nolwelo. Ubushushu beMedia bubandakanya amaqondo aphezulu, aphakathi, aqhelekileyo, kunye namaqondo aphantsi. Izinto ze-WCB zilungele -29 ℃ ukuya ku-425 ℃, ngelixa izinto zensimbi ezingenasici zifanelekile kuluhlu olubanzi lobushushu. Ixabiso eliphantsi loMgangatho waseRashiya wokunyuka kwesiqu iivalvu zesango ezinamaphiko zithathwe ngokuthe ngqo kumzi-mveliso waseShenchi; Ukuthengwa kwezinto ezininzi kunika amaxabiso angcono. Amatywina anokuba yi-EPDM okanye i-PPL ukuhlangabezana neemfuno zeendaba ezahlukeneyo zobushushu. Imigangatho yeflange yesiko iyaxhaswa, iqhelana neenkqubo ezahlukeneyo zemibhobho kubandakanya imigangatho yesiRashiya, isiJamani, kunye neMelika.

Ukuthengwa kunye neNkonzo Njengomvelisi waseTshayina we-Standard Standard yaseRashiya ephakamayo i-valve yesango eline-flanged, i-Shenchi ibonelela ngolawulo lomgangatho wokuphela ukuya ekupheleni ukusuka kwi-casting ukuya kwimveliso egqityiweyo. Ixabiso eliphantsi loMgangatho waseRashiya wokunyuka kwesiqu seevalvu zesango ezinamaphiko zibonelelwa ngokuthe ngqo ukusuka kumzi-mveliso ngamaxabiso angafihliyo kwaye akukho zimpawu ziphakathi. I-ODM kunye ne-OEM ngokwezifiso ziyaxhaswa; imathiriyeli, iidayamitha, imigangatho yeflange, kunye neendlela zokusebenza zinokuhlengahlengiswa njengoko kufuneka. Ukusebenza okuphezulu komgangatho waseRashiya wokunyuka kwe-stem flanged iivalvu zesango zomelele kwaye zineendleko eziphantsi zokulondolozwa. Iisampulu zingenziwa, kwaye amaxesha okuhanjiswa kweeodolo ezininzi azinzile. Abathengi behlabathi bamkelekile ukuba baqhagamshelane ne-Shenchi ngeenkcukacha zobuchwepheshe ezineenkcukacha kunye nekota
