Umgangatho oPhezulu woShishino Y uhlobo lweglowubhu yesivalo somthengisi waseTshayina
Yintoni ivalve yeglowubhu yodidi luka-Y?
Y chwetheza ivalve yeglowubhu,iqhele ukuyilwa kwaye yenziwe ngokomgangatho waseJamani kunye nomgangatho waseYurophu EN13709.njengesiqhelo, yivalve evalayo evalayo esetyenziselwa ukuqalisa, ukumisa okanye ukulawula ukuhamba kusetyenziswa ilungu lokuvala elibizwa ngokuba yidiski.iY chwetheza ivalve yeglowubhuzezona zifanelekileyo kwaye zisetyenziswa ngokubanzi ukulawula okanye ukumisa ukuhamba kolwelo okanye irhasi ngombhobho wokungqusha nokulawula ukuhamba kolwelo kwaye zisetyenziswa ngokubanzi kwimibhobho yobungakanani obuncinci.
I-Bellows inobomi benkonzo obulinganiselweyo, oku kuthetha ukuba kunokwenzeka ukuba ukugqabhuka kunokwenzeka.Yiyo loo nto indibano yokupakisha eqhelekileyo isoloko ibandakanyiwe kwibhonethi ene-bellows. Ke i-bellows seal lutywino olongezelelweyo lokutywina kwiivalvu zesango, ilungele iimeko ezithile zokusebenza ezinzima.
ngokwesiqhelo kukho iipateni ezingundoqo ezintathu zomzimba okanye uyilo lweY chwetheza ivalve yeglowubhu:
- 1).Ipateni eMiselweyo (kunye nePateni yeTee okanye iT – Ipateni okanye uZ – Ipateni)
- 2).Ipateni ye-engile
- 3).Ipateni ye-Oblique (ekwaziwa ngokuba yi-Wye Pattern okanye i-Y-Pateni)
Iimpawu eziphambili zevalve yeglowubhu yodidi lwe-Y?
Ngokukodwa iinkqubo zeekhemikhali ulwelo olukwimibhobho luhlala luyityhefu, lusebenza ngeradioactive kwaye luyingozi.Iivalvu zeglowubhu zitywinwe ngomvumbozisetyenziselwa ukuthintela ukuvuza kwayo nayiphi na imichiza eyityhefu emoyeni.Isixhobo somzimba sinokukhethwa kuzo zonke izixhobo ezikhoyo, I-bellow inokunikezelwa ngezinto ezahlukeneyo ezifana ne-316Ti, 321, C276 okanye i-Alloy 625.
- 1) .Kukho uluhlu olubanzi lwezakhono njengoko lufumaneka kwipatheni eqhelekileyo (ipateni yokolula), ipateni ye-Angle, kunye nepateni ye-Wye (ipateni ye-Y).
- 2) .Intsimbi yentsimbi itywina isiqu esishukumayo kwaye inyusa ukuqina kweevalvu ezipakishweyo zokutywina.
- 3) .Amatywina amabini esibini: a) Isitulo sangasemva kwindawo evulekileyo;b) Ukupakishwa kwegrafu.
- 4) .Iivalve ezivalwe ngeBellow-sealing zivame ukuvuza zivavanywa kusetyenziswa i-spectrometer yobuninzi ukubona amazinga okuvuza angaphantsi kwe-1x10E-06 std.cc/sec.Uyilo lokutywinwa kabini (i-bellows seal kunye nokupakishwa kwesiqu) ukuba i-bellows ayiphumelelanga, ukupakishwa kwe-valve stem kuya kuphepha. ukuvuza, kunye nokuhambelana nemigangatho yokuqina yamazwe ngamazwe;
