Ikhwalithi ephezulu Yezimboni Y yohlobo lwe-globe valve umphakeli wefektri waseChina
Iyini i-valve yeglobe engu-Y?
Y thayipha i-valve yomhlaba,imvamisa iklanywa futhi yakhiwe ngokuvumelana nezinga laseJalimane kanye nezinga laseYurophu elingu-EN13709.njengokuvamile, kuyivalvu evalayo enyakazayo ehambisanayo esetshenziselwa ukuqala, ukumisa noma ukulawula ukugeleza kusetshenziswa ilungu lokuvala elibizwa ngokuthi idiski.iY thayipha i-valve yomhlabaafaneleka kakhulu futhi asetshenziswa kabanzi ukulawula noma ukumisa ukugeleza koketshezi noma igesi ngepayipi ukuze kuncinze futhi kulawule ukugeleza koketshezi futhi ngokuvamile asetshenziswa kumapayipi kasayizi omncane.
I-Bellows inempilo yesevisi elinganiselwe, okusho ukuthi kungenzeka ukuthi ukuphuka kungenzeka.Kungakho umhlangano wokupakisha ojwayelekile uhlala ufakwe kubhonethi enezinsimbi. Ngakho-ke i-bellows seal iwukuvala okungeziwe kwamavalvu esango, ifanele izimo zokusebenza ezinzima.
ngokuvamile kunamaphethini amathathu okuqala omzimba noma imiklamoY thayipha i-valve yomhlaba:
- 1).Iphethini Ejwayelekile (futhi njengephethini yeTee noma i-T - Iphethini noma i-Z - Iphethini)
- 2).Iphethini ye-engeli
- 3).Iphethini e-Oblique (eyaziwa nangokuthi Iphethini ye-Wye noma i-Y - Pattern)
Izici eziyinhloko ze-valve yeglobe yohlobo lwe-Y?
Ikakhulukazi izinqubo zamakhemikhali uketshezi olusemapayipini ngokuvamile lunobuthi, lukhipha imisebe futhi luyingozi.I-Bellows ivala ama-valve e-globezisetshenziselwa ukuvimbela ukuvuza kwanoma iyiphi ikhemikhali enobuthi emkhathini.Impahla yomzimba ingakhethwa kuzo zonke izinto ezitholakalayo, I-bellow inganikezwa ngezinto ezahlukene ezifana ne-316Ti, 321, C276 noma i-Alloy 625.
- 1).Kunobubanzi obuhlukahlukene bamakhono njengoba butholakala kuphethini evamile(iphethini yokuqina), iphethini ye-engeli, kanye nephethini ye-Wye(iphethini engu-Y).
- 2) .Izinsimbi zensimbi zivala isiqu esinyakazayo futhi kukhulisa ukuqina kwama-valve ophawu lwesiqu.
- 3).Ama-stem seal seal seal: a) Isihlalo sangemuva sisendaweni evulekile;b) Ukupakisha kwe-graphite.
- 4).Amavalvu avaliwe avamise ukuvuza ahlolwe kusetshenziswa i-spectrometer enkulu ukuze kutholwe amazinga okuvuza angaphansi kuka-1x10E-06 std.cc/sec.Umklamo wokuvala kabili (bellows seal kanye nokupakishwa kwesiqu) uma ukuvuza kuhluleka, ukupakishwa kwesiqu se-valve nakho kuzogwema. ukuvuza, futhi ngokuhambisana nezindinganiso zamazwe ngamazwe zokuqina;
