Ivalvu yesango ehleliyo neqinileyo
Yintoni ivalvu yesango ehlala iqinile (RSGV)?
Ivalvu yesango ehleliyo neqinileyo (RSGV),umgaqo woyilo obaluleke kakhulu xa kukhethwa ukuba usetyenziswe kwiinkqubo zokusasazwa.
Iivalvu yesango ehleliyo eqinileyoIqulethe i-wedge egqunywe ngokupheleleyo ngerabha ye-EPDM ebotshelelwe ngokusisigxina kwi-wedge kwaye idibana ne-ASTM D249. Umzimba wevalvu, ibhonethi, 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).Ivalvu yesango ehleli phantsi ezinzileyoingasetyenziswa ngeSpur okanye iBevel Gear, kunye ne-actuator yombane.
iivalvu zesango ezihleli phantsi eziqinileyozithandwa 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 resilient seat gate valve (RSGV)?
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
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
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.
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.
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.
