Iivalvu zeSango eziQinisekayo zoMvelisi waseTshayina zamanzi okusela eziqinisekisiweyo yiWRAS
Yintoni iiValve zeSango eziQinisekayo?
Iivalvu zeSango eziQinisekayo,umgaqo woyilo obaluleke kakhulu xa kukhethwa ukuba usetyenziswe kwiinkqubo zokusasazwa.
IiValve zeSango eziQinisekayo 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-NORTECH Resilient Gate Valves
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.
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.
