Ivalvu yeSango eQinisekileyo neSiqingqi esiNgakhuphukiyo iDIN3352-F4 umzi-mveliso waseTshayina
Yintoni iValve yeSango leStem eliNgeliyo eliKhuphukayo?
Ivalvu yeSango leStem eliNgaphumiyo,umgaqo woyilo obaluleke kakhulu xa kukhethwa ukuba usetyenziswe kwiinkqubo zokusasazwa.
I-Non Rising Stem Gate Valve ine-wedge egqunywe ngokupheleleyo ngerabha ye-EPDM ebotshelelwe ngokusisigxina kwi-wedge kwaye idibana ne-ASTM D249. Umzimba we-valve, i-bonnet, kunye nepleyiti yokuzalisa zigqunywe nge-fusion bonded epoxy (FBE), ibukeka intle kwaye ikhuselekile kakhulu.
Iivalvu zeSango leSitem esiNgekho eSinyukayo zithandwa kakhulu kwiimveliso.
- 1) Ukuvalwa okugqibeleleyo: ukutywinwa kwe-bubble ejikelezayo.
- 2) Ixabiso eliphantsi: isihlalo serabha sivulcanized kwi-wedge, akukho mfuneko yokulungisa isihlalo sevalvu ngakumbi.
- 3) Isakhiwo esilula kunye nokugcinwa okulula
Iimpawu eziphambili ze-NORTECHNon Rising Stem Gate Valve
Umzimba yenziwe ngentsimbi ethambileyo ngokubumba ngendlela echanekileyo,Yenzelwe yisoftware ye-3D, enohlalutyo lwezinto ezilinganiselweyo zesakhiwo. I-coefficient yokhuseleko ingaphezulu kwe-2.5. Umjelo osezantsi ogudileyo wenzelwe ukuthintela ukuqokelelana kokungcola nokuqinisekisa ukumelana nokuhamba kwamanzi okuncinci.
IsiquYenziwe ngentsimbi engatyiwayo ngokuqengqeleka. Uhlobo oludibeneyo, oluthintela ukusetyenziswa kweendandatho zesiqingatha zobhedu ukunciphisa ububanzi besiqu. Isikrufu sohlobo lweleli esiguquliweyo esigudisiweyo sikhutshwe. Ipolishi yesipili sehlabathi, ilingana kakuhle neendandatho ze-O, ukuqinisekisa ukuba ukujikeleza okugudileyo kunye ne-torque encinci.
Iibholiti zebanga lesi-8.8 zidibanisaibhonethikwaye umzimba, iibholiti zigqunywe yi-wax enyibilikayo eshushu ekhusela iibholiti ekungcoleni. I-gasket ephakathi kwebhonethi nomzimba yenziwe nge-EPDM. Isiciko sevalvu senziwe ngomatshini one-retaining groove, qiniseka ukuba i-gasket yerabha ayizukukhutshelwa ngaphandle phantsi koxinzelelo lwamanzi aphezulu.
Ukuveliswa okulungele indalo
Iindawo zerabha zenziwe nge-EPDM okanye i-NBR esemgangathweni ophezulu, ehambelana neemfuno zamanzi okusela, ukuthintela ingxaki yerabha eqhelekileyo enokuthi ivelise iintsholongwane. Ezi mveliso azivunywanga kuphela yimigangatho yomgangatho wesizwe saseTshayina kwiimveliso ezinxulumene namanzi okusela, kodwa zivunyiwe yi-WRAS e-UK kunye ne-ACS eFransi. I-stem nut yenziwe kwaye iqengqelwe kwi-national standard brass rod (umxholo ophantsi we-lead), kwaye akukho ngcoliseko emanzini.
Ukufakwa kunye nokusebenza lula
Sinikezela ngeentlobo ezahlukeneyo zonxibelelwano ezifana noqhagamshelo lweflange, isokhethi yombhobho wePVC, isokhethi yombhobho wesinyithi we-uctile, ukunciphisa njl. Uyilo olukhethekileyo loqhagamshelo lunokwenziwa ngokwezifiso ngokwezicelo.yabasebenzisi.
Ivalvu ingavalwa ngokupheleleyo kwaye ifikeleleke xa ivuza ngetorque encinci. Itorque yokusebenza yokwenyani yi-80% kuphela yobubanzi, kwaye iivalvu zesango zinokuthwala i-MST ye-3 * DN NM. Iimveliso ziphumelele uvavanyo lobomi lwamaxesha angama-5000. Kwiivalvu ezinobubanzi obukhulu, singanikezela ngezixhobo zokonga abasebenzi, ukuqinisekisa ukuba zonke iivalvu zinokuvulwa kwaye zivaliwe ngumntu omnye. Ivili lesandla liqinile, linobukhulu obuchanekileyo, lihambelana kakuhle nesiqu sevalvu, imilo ihambelana noomatshini babantu, ukuqinisekisa ukusebenza lula.
