Ivalvu yokujonga iGlobe yeZimboni ekumgangatho ophezulu Umvelisi womthengisi wefektri waseTshayina
Yintoni ivalvu yokujonga iGlobe?
Ivalvu yokujonga iglobe Yenzelwe kwaye yenziwa ngokwemigangatho yangaphambili yaseJamani, iDIN kunye nemigangatho yaseYurophu yanamhlanje i-EN13709.Isetyenziswa kakhulu kumazwe akwiManyano yaseYurophu.
yivalvu yayo yokuvala ehamba ngomgca esetyenziselwa ukuqala, ukumisa okanye ukulawula ukuhamba kusetyenziswa ilungu lokuvala elibizwa ngokuba yidiski. Ukuvulwa kwesihlalo kutshintsha ngokulinganayo ngokuhamba kwediski efanelekileyo kwimisebenzi ebandakanya ukulawulwa kokuhamba. Iivalvu zeDIN-EN Globe zezona zifanelekileyo kwaye zisetyenziswa kakhulu ukulawula okanye ukumisa ukuhamba kolwelo okanye igesi ngepayipi ukuze kuthintelwe kwaye kulawulwe ukuhamba kolwelo kwaye zihlala zisetyenziswa kwiipayipi ezincinci.
iIvalvu yokujonga iglobeingasetyenziselwa neenjongo zokuqhobosha. Iivalvu ezininzi ezihlala umntu omnye zisebenzisa ulwakhiwo lwekheji okanye uhlobo lwe-retainer ukugcina iringi yesihlalo, ukubonelela ngesikhokelo seplagi yevalvu, kunye nokubonelela ngeendlela zokuseka iimpawu ezithile zokuhamba kwevalvu. Ingatshintshwa ngokulula ngokutshintsha iindawo zokusika ukuze kutshintshwe uphawu lokuhamba okanye kubonelelwe ngokuhamba komthamo ophantsi, ukuncitshiswa kwengxolo, okanye ukunciphisa okanye ukususa i-cavitation.
ngokwesiqhelo kukho iipateni ezintathu eziphambili zomzimba okanye uyilo Ivalvu yokujonga iglobe:
- 1). Ipateni eQhelekileyo (kwakhona njengeTee Pattern okanye uT – Ipateni okanye uZ – Ipateni)
- 2) .Iphethini ye-Angle
- 3). Ipateni ye-Oblique (ekwaziwa ngokuba yiWye Pattern okanye iY – Pattern)
Iimpawu eziphambili zevalvu yokujonga iGlobe
Ipateni esemgangathweni (ipateni ethe tye)
Ipateni ye-engile
Ipateni eqhelekileyo enetywina leentsimbi
- 1). Umgama omfutshane wokuhamba kwediski (stroke) phakathi kweendawo ezivulekileyo nezivaliweyo,Ivalvu yokujonga iglobezilungele ukuba ivalvu kufuneka ivulwe kwaye ivalwe rhoqo;
- 2) .Izakhono ezilungileyo zokutywina
- 3). Kukho uluhlu olubanzi lwezakhono njengoko zifumaneka kwipateni esemgangathweni (ipateni eyomeleleyo), ipateni ye-Angle, kunye nepateni ye-Wye (ipateni ye-Y).
- 4). Ivalvu yeglobhu ye-DIN-EN ingasetyenziswa njengevalvu ye-SDNR, ivalvu yokujonga iglobe ngokutshintsha uyilo kancinci.
- 5). Kulula ukulungisa nokulungisa izihlalo, ngeenjongo ezahlukeneyo.
- 6). Ikwazi ukuthomalalisa kakuhle, ngokutshintsha ulwakhiwo lwesihlalo kunye nediski.
Ukulawula uyilo lweediski
Ukulinganisela uyilo lwediski, i-DN200 nangaphezulu
