Ivalvu yesango lesihlalo serabha yaseTshayina Intengiso epheleleyo Umthengisi wefektri yaseTshayina
Yintoni ivalvu yesango lesihlalo serabha?
Ivalvu yesango lesihlalo serabha,umgaqo woyilo obaluleke kakhulu xa kukhethwa ukuba usetyenziswe kwiinkqubo zokusasazwa.
IIvalvu yesango lesihlalo serabhaIqulethe 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 lesihlalo serabhaingasetyenziswa ngeSpur okanye iBevel Gear, kunye ne-actuator yombane.
Iimpawu eziphambili ze-NORTECHIvalvu yesango lesihlalo seRubber
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.
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.
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.
