I-Rising Stem Soft Seal Cast Iron Gate Valve yoMvelisi waseTshayina
Yintoni iSoft Seal Gate Valve?
Ivalvu yeSango lokuTywina elithambileyo,umgaqo woyilo obaluleke kakhulu xa kukhethwa ukuba usetyenziswe kwiinkqubo zokusasazwa.
I-Soft Seal 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. Uqwalaselo olunokukhethwa lukwabandakanya i-Non-Rising Stem (NRS) okanye i-Outside Screw & Yoke (OS&Y). I-Soft Seal Gate Valve ikwasebenza nge-Spur okanye i-Bevel Gear, kunye ne-actuator yombane.
Iivalvu zeSango leSeal ezithambileyo zithandwa kakhulu kwizicelo zoshishino.
- 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-NORTECH Soft Seal 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.
Isakhelo seiwejiYenziwe ngentsimbi ethambileyo ngokubumba isanti egqunywe kwangaphambili, i-wedge igqunywe yi-EPDM ngokupheleleyo. Uyilo lwetywina eliphindwe kabini, umgca ngamnye wetywina ungasebenza ngokuzimeleyo
Ukuveliswa okulungele indalo
Umphezulu wangaphakathi nowangaphandle wevalvu ugqunywe ngumgubo we-epoxy ococekileyo yi-fusion bonded epoxy (FBE), ubukhulu obuphakathi bungaphezulu kwe-250um. Ukunamathela kwengubo kuqinile, akuyi kutshatyalaliswa phantsi kovavanyo lwamandla okuchaphazeleka lwe-3J. Iindawo zangaphakathi zinokuhlangabezana neemfuno zokhuseleko lokusingqongileyo, kwaye zingasetyenziselwa ngqo amanzi okusela, ukutya kunye nendawo yamayeza. Inkqubo yokugquma umgubo we-electrostatic inokuthembisa amandla aphezulu okunamathela kunye nokumelana okunamandla kokugqwala.
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. Iivalvu zesango zinokusetyenziswa yi-actuator yombane, amavili esandla, isiciko sesitshixo okanye isitshixo esikhethekileyo. Kulula ukufaka iivalvu kwiindawo ezahlukeneyo zemigca yepayipi. Ngaphandle kokufakelwa ngokuthe nkqo, iivalvu zinokufakwa ngokuthe tye. Kwezinye iindawo ezimxinwa, ungakhetha indlela yokufaka efanelekileyo yokusebenza kweevalvu.
Ukugcinwa lula
Indandatho yokutywina ingatshintshwa ngaphandle kokunqumla amanzi, kulula ukuyilungisa kwaye inciphise ixesha lokulungisa kangangoko kunokwenzeka. Ingqubano encinci kakhulu phakathi kwe-brass bushing kunye ne-"O" type seal, iya kuqinisekisa ukuba indandatho yokutywina ihlala ixesha elide. I-torque ephezulu yokusebenza iphantsi kolawulo.
