Ingcindezi Yekhwalithi Ephakeme Yezimboni evalwe uphawu lwevalvu yesheke yebhonethi Umkhiqizi wefektri waseChina
Iyini ivalvu yokuhlola ibhonethi evalwe ngomfutho?
Amavalvu okuhlola, amavalvu angabuyi, aklanyelwe ukuvimbela ukuhlehla kokugeleza ohlelweni lwamapayipi.Lawa ma-valve acushwa yizinto ezigelezayo epayipini.Ukucindezela koketshezi oludlula ohlelweni kuvula i-valve, kuyilapho ukuguqulwa kokugeleza kuzovala i-valve.Ukuvalwa kufezwa ngesisindo somshini wokuhlola, ngokucindezelwa emuva, ngesiphethu, noma ngenhlanganisela yalezi zindlela.
ivalvu yokuhlola ibhonethi evalwe ngomfutho,ivalve yokuhlola i-swing eklanywe futhi yakhiqizwa ngokuya nge-ASME B16.34,hlola futhi uhlole ku-API598,API6D.
Lokho kuvuleka kufanele kucace ukuze kudlule noma yini.I-disc inamathiselwe kuhinge, ngakho-ke i-disc ingashwibeka ivuleke noma ivalwe lapho uketshezi lushaya idiski.Kufana nomnyango oyindilinga.Isiqondiso sokugeleza yinto ebaluleke kakhulu uma usebenzisa lawa ma-valve.
Njengoba kushiwo ngaphambili, i-valve yokuhlola i-swing ingeyalapho ufuna uketshezi oluhamba ohlangothini olulodwa kuphela.Omunye umniningwane obalulekile mayelana nalawa ma-valve ukuthi awadingi amandla angaphandle, okuwenza alungele ukusetshenziswa okubanzi.Ziphinde zivumele uketshezi ukuba ludlule ngaphandle kokunciphisa ukugeleza kakhulu lapho luvuleke ngokugcwele.Ama-valve okuhlola ama-Swing ngokuvamile afakwa ngokuhlanganyela nama-valve esango ngoba ahlinzeka ngokugeleza okukhululekile.Anconywa kolayini onokugeleza kwesivinini esiphansi futhi akufanele asetshenziswe kolayini abaphehlayo uma ukubhakuzisa noma ukubhakuza okuqhubekayo kungalimaza izinto zokuhlala.Lesi simo singalungiswa kancane ngokusebenzisa i-lever yangaphandle nesisindo.
Izici eziyinhloko zevalvu yokuhlola ibhonethi evalwe ngomfutho
Izici Eziyinhloko zeivalvu yokuhlola ibhonethi evalwe ngomfutho:
- ● Umzimba nekhava: I-Precision machined castings.stem ayingeni emzimbeni.
- ● Idiski: Ukwakhiwa okuqinile kocezu olulodwa ukumelana nokushaqeka okukhulu kwesevisi yevalvu yesheke.Inobuso obuqinile obuno-13Cr, i-CoCr alloy, i-SS 316, noma i-Monel, iphansi futhi yagqitshwa kuze kube sekugcineni kwesibuko.I-SS 316 disc ene-CoCr alloy ebheke nayo iyatholakala.
- ● Ukuhlanganiswa kwediski: Idiski engaphenduki iboshelwa ngokuvikelekile kusiphanyeko sediski ngenadi lokukhiya kanye nephinikhodi ye-cotter.Isiphanyeko sediski sisekelwa iphinikhodi ye-hinge ye-disc eqinile yezimfanelo ezinhle kakhulu zokuthwala.Zonke izingxenye zifinyeleleka phezulu ukuze ziseviswe kalula.
