I-Stem engakhuphukiyo i-Resilient yeSango i-Valve ye-DIN3352-F4 yaseTshayina
Yintoni iValve yeSango yeSithi eNgaphumiyo?
IValve yeSango yeSithi enganyukiyo,umgaqo woyilo obalaseleyo ekukhetheni ukusetyenziswa kwiinkqubo zokusasaza.
I-Valve yeSango ye-Stem enganyukiyo iqulethe 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.
I-Valve yeSango yeSithi eNgaphumiyo ithandwa kakhulu kwisicelo semizi-mveliso.
- 1) Ukutywinwa okugqibeleleyo: ukutywinwa kweqamza eline-bi-directional.
- 2) Ixabiso eliphantsi: isitulo serabha sivulwe kwi wedge, akukho mfuneko yokulungiswa kwesihlalo sevalvu.
- 3)Isakhiwo esilula kunye nokugcinwa okulula
Iimpawu eziphambili ze-NORTECHNon Rising Stem Gate Valve
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 yehlabathi, ilingana ne-O ring kakuhle, ukuqinisekisa ukuba ukujikeleza okugudileyo kunye netorque encinci.
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
Amalungu erabha ayenziwe ngomgangatho ophezulu we-EPDM okanye i-NBR, ehambelana neemfuno zamanzi okusela, ukuphepha ingxaki yerabha eqhelekileyo enokuthi ivelise i-microorganism.Imveliso ayivunywanga kuphela yimigangatho yesizwe yaseTshayina yamanzi okusela 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.
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.Kwiivalve ezinobubanzi obukhulu, sinokunikela ngezixhobo zokulondoloza abasebenzi, ukuqinisekisa ukuba zonke iivalve zinokuvulwa kwaye zivaliwe ngumntu omnye.I-handwheel yomelele, inemilinganiselo echanekileyo, ihambelana kakuhle ne-valve stem, imilo ihambelana noomatshini bomntu, ukuqinisekisa ukusebenza okulula.
