Ivalve yesango ehleliyo ehleliyo
Yintoni ivalve yesango ehleliyo (RSGV)?
Ivalve yesango ehleliyo (RSGV),umgaqo woyilo obalaseleyo ekukhetheni ukusetyenziswa kwiinkqubo zokusasaza.
Iivalve yesango ehleliyo eyomelelaiqulethe i-wedge efakwe ngokupheleleyo kunye ne-EPDM irabha eboshwe ngokusisigxina kwi-wedge kwaye idibana ne-ASTM D249.Umzimba wevalvu, ibhonethi, kunye nepleyiti yokuhlohlwa zigqunywe nge-fusion ebond epoxy (FBE), ibukeka intle kunye nokhuseleko olugqwesileyo.Uqwalaselo oluKhethayo lukwabandakanya iSithi esinganyukiyo (NRS) okanye iSikrikri sangaphandle kunye neYoke (OS&Y).Ivalve yesango ehleliyo eyomelelayoinokusebenza nge-Spur okanye i-Bevel Gear, kunye ne-actuator yombane.
iivalvu zesango elihlalayo elihlalayozithandwa kakhulu kwisicelo semizi-mveliso.
- 1) Ukutywinwa okugqibeleleyo: ukutywinwa kweqamza ezimbini.
- 2) Ixabiso eliphantsi: isitulo serabha sivulwe kwi wedge, akukho mfuneko yokulungiswa kwesihlalo sevalvu.
- 3)Isakhiwo esilula kunye nokugcinwa okulula
Iimpawu eziphambili ze-NORTECH zomelela ivalve yesango ehleliyo (RSGV)?
Umzimba yenziwe nge-iron ductile ngokubumba okuchanekileyo,Yayilwa yi-software ye-3D, kunye nohlalutyo olusisigxina lwe-structure.I-coefficient yokhuseleko ingaphezulu kwe-2.5.Ijelo elisezantsi elithambileyo lenzelwe, ukuphepha ukuqokelela ukungcola kunye nokuqinisekisa ukuxhathisa ukuhamba okuncinci.
Isiquyenziwe ngentsimbi engenasici ngokuqengqeleka.Uhlobo oludityanisiweyo, ukuphepha ukusetyenziswa kwamakhonkco esiqingatha sobhedu ukunciphisa ububanzi besikhondo.isikrufu sodidi lweleli egudileyo siyakhutshwa.Ipolishi yesipili sehlabathi, ilingana ne-O ring kakuhle, ukuqinisekisa ukuba ukujikeleza okugudileyo kunye netorque encinci.
Isakhelo sewedgeyenziwe ngentsimbi ye-ductile ngokubumba kwesanti efakwe ngaphambili, i-wedge igqunywe yi-EPDM ngokupheleleyo.Uyilo olutywiniweyo oluphindwe kabini, umgca wokutywina ngamnye unokusebenza ngokuzimeleyo.
Iibholithi zebanga lesi-8.8 ziqhagamshelaibhonethikunye nomzimba, iibholiti zagqunywa yi-wax enyibilikayo eshushu ekhusela iibholithi zomhlwa.Igasket phakathi kwebhonethi kunye nomzimba yenziwe nge-EPDM.Isigqubuthelo sevalvu senziwe ngoomatshini bokugcina umjelo, qiniseka ukuba igasket yerabha ayisayi kukhutshelwa ngaphandle phantsi koxinzelelo oluphezulu lwamanzi.
Imveliso ehambelana nokusingqongileyo
Umphezulu wangaphakathi nangaphandle wevalve uqatywe ngomgubo we-epoxy ococekileyo ngokudityaniswa kwe-epoxy (FBE), ubukhulu obuphakathi bungaphezulu kwe-250um.Ukuncamatheliswa kwengubo yomelele, ayisayi kutshatyalaliswa phantsi kovavanyo lwamandla e-3J.Amalungu angaphakathi angahlangabezana neemfuno zokhuseleko lokusingqongileyo, kwaye angasetyenziselwa amanzi okusela, ukutya kunye nendawo yokuxuba amayeza ngokuthe ngqo.Inkqubo yokwambathisa ngomgubo we-electrostatic inokuthembisa amandla ancamatheleyo aphezulu kunye nokumelana nokugqwala okuqinileyo.
Amalungu erabha ayenziwe ngomgangatho ophezulu we-EPDM okanye i-NBR, ehambelana neemfuno zamanzi okusela, ukuphepha ingxaki yerabha eqhelekileyo enokuthi ivelise i-microorganism. iimveliso ezinxulumeneyo, kodwa zivunywe yi-WRAS e-UK kunye ne-ACS e-France.I-stem nut yenziwe yaza yaqengqeleka ukusuka kumgangatho wesizwe wentonga yobhedu (umxholo ophantsi welothe), kwaye akukho ngcoliseko emanzini.
Ufakelo olulula kunye nokusebenza
Sinikezela ngeentlobo ezahlukeneyo zojongano olunjengonxibelelwano lweflange,isokethi yombhobho wePVC, isiseko sombhobho wentsimbi uctile,ukunciphisa njl.Uyilo loqhagamshelo olukhethekileyo lunokwenziwa ngokwezicelo.
yabasebenzisi.Iivalvu zesango zinokuqhutywa yi-actuator yombane, amavili esandla, ikepusi yesitshixo okanye isitshixo esikhethekileyo.Kukulungele ukufaka iivalve kwiindawo ezahlukeneyo zemigca yombhobho.ngaphandle kofakelo oluthe nkqo, iivalvu nazo zinokufakwa ngokuthe tye.Kwezinye iindawo ezimxinwa, unokukhetha indlela yofakelo olulungele ukusebenza kweevalvu.
Ivalve inokuvalwa ngokupheleleyo kwaye ifikelele kwi-o evuzayo ngetorque encinci.I-torque yangempela yokusebenza i-80% kuphela yobubanzi, kwaye iivalve zesango zinokuthwala i-MST ye-3 * DN NM Iimveliso ziphumelele uvavanyo lobomi ngamaxesha angama-5000.Kwimibhobho yobukhulu obukhulu, sinokunikela ngezixhobo zokulondoloza abasebenzi, ukuqinisekisa ukuba zonke iivalve zinokuvulwa kwaye zivalwe ngumntu omnye.I-handwheel yomelele, inemilinganiselo echanekileyo, ihambelana kakuhle ne-valve stem, imilo ihambelana noomatshini bomntu, ukuqinisekisa ukusebenza okulula.
Ukugcinwa lula
Umsesane wokutywina unokutshintshwa ngaphandle kokunqunyulwa kwamanzi, kulula ukugcinwa kunye nokunciphisa ixesha lokugcina ngokusemandleni.Ingxabano encinci kakhulu phakathi kwe-brass bushing kunye ne-"O" uhlobo lwetywina, luya kuqinisekisa ubomi obude betywina. umsesane.Ubukhulu.itorque yokusebenza iphantsi kolawulo.
