Umthengisi we-valve yeglobe ye-Y yoMgangatho oPhezulu eTshayina
Yintoni ivalvu yeglobhu yohlobo lwe-Y?
Ivalvu yeglobhu yohlobo lwe-Y,Ngokwesiqhelo iyilwe kwaye yenziwa ngokwemigangatho yaseJamani kunye nemigangatho yaseYurophu i-EN13709. Njengesiqhelo, ivalvu yayo yokuvala ehamba ngomgca isetyenziselwa ukuqala, ukumisa okanye ukulawula ukuhamba kwamanzi kusetyenziswa ilungu lokuvala elibizwa ngokuba yidiski.Ivalvu yeglobhu yohlobo lwe-YZilungele kakhulu kwaye zisetyenziswa kakhulu ukulawula okanye ukumisa ukuhamba kolwelo okanye igesi ngombhobho ukuze zithintele kwaye zilawule ukuhamba kolwelo kwaye zihlala zisetyenziswa kwiipayipi ezincinci.
IiBellows zinobomi obulinganiselweyo benkonzo, nto leyo ethetha ukuba kunokwenzeka ukuba ziqhekeke. Yiyo loo nto indibano yokupakisha eqhelekileyo isoloko ifakwa kwibhonethi exhotyiswe ngeBellows. Ngoko ke iBellows seal sisixhobo esongezelelweyo sokuvala iivalvu zesango, ifanelekile kwiimeko ezithile zokusebenza ezinzima.
ngokwesiqhelo kukho iipateni ezintathu eziphambili zomzimba okanye uyiloIvalvu yeglobhu yohlobo lwe-Y:
- 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 yeglobhu yohlobo lwe-Y?
Ngokukodwa kwiinkqubo zeekhemikhali, ulwelo olukwimibhobho ludla ngokuba yityhefu, lunemisebe kwaye luyingozi.Iivalvu zeglobhu ze-Bellows sealzisetyenziselwa ukuthintela ukuvuza kwayo nayiphi na ikhemikhali enobuthi emoyeni. Izinto zomzimba zingakhethwa kuzo zonke izinto ezikhoyo, kwaye ezi zinto zingafumaneka ngezinto ezahlukeneyo ezifana ne-316Ti, 321, C276 okanye i-Alloy 625.
- 1). Kukho uluhlu olubanzi lwezakhono njengoko zifumaneka kwipateni esemgangathweni (ipateni eyomeleleyo), ipateni ye-Angle, kunye nepateni ye-Wye (ipateni ye-Y).
- 2). Intsimbi evuthuzayo iyawuvala umthi oshukumayo kwaye yonyusa ukuqina kweevalvu zesitywini sesiqu ezipakishiweyo.
- 3).Izitywino ezimbini zesibini zesiqu: a) Isihlalo sangasemva kwindawo evulekileyo; b) Ukupakisha iGraphite.
- 4). Iivalvu ezitywinwe ngentsimbi zihlala zivavanywa ukuvuza kusetyenziswa i-mass spectrometer ukubona amazinga okuvuza angaphantsi kwe-1x10E-06 std.cc/sec. Uyilo lokutywina kabini (i-bellows seal kunye ne-stem packing) ukuba ii-bellows ziyasilela, ukupakisha i-valve stem packing kuya kuthintela ukuvuza, kwaye ngokuhambelana nemigangatho yamazwe ngamazwe yokuxinana;
