Izinzuzo ze-valve yesango:
(1) Ukumelana noketshezi oluncane Ngenxa yokuthi umzila wangaphakathi ophakathi womzimba we-valve wesango uqondile, i-medium ayishintshi isiqondiso sayo sokugeleza lapho igeleza nge-valve yesango, ngakho-ke ukumelana noketshezi kuncane.
(2) I-torque yokuvula neyokuvala incane, futhi ukuvuleka nokuvala kusindisa umsebenzi.Ngenxa yokuthi isiqondiso sokunyakaza kwesango sibhekene nesiqondiso sokugeleza okuphakathi lapho i-valve yesango ivulwa futhi ivaliwe, ukuvulwa nokuvalwa kwe-valve yesango kusindisa kakhulu umsebenzi uma kuqhathaniswa ne-valve yokumisa.
(3) Ukuqondisa kokugeleza kwe-medium akukhawulelwe, futhi okuphakathi kungageleza kunoma iyiphi indlela kusuka ezinhlangothini zombili ze-valve yesango ngaphandle kokuphazamisa ukugeleza futhi ngaphandle kokunciphisa ukucindezela, futhi inhloso yokusetshenziswa ingafinyelelwa.Ifaneleka kakhulu kumapayipi lapho isiqondiso sokugeleza se-medium singashintsha.
(4) Ubude besakhiwo bufushane ngenxa yokuthi isango le-valve yesango libekwe mpo emzimbeni we-valve, futhi i-valve disc ye-valve yokumisa ibekwe yavundlile emzimbeni we-valve, ngakho ubude besakhiwo bufishane kunaleso sokumisa. i-valve.
(5) Ngokusebenza kahle kokuvala, indawo yokuvala iguguleka kancane uma ivulwe ngokugcwele.
(6) Uma ivuleke ngokugcwele, ukuguguleka kwendawo evalekayo yinto esebenzayo kuncane kunaleyo yevalvu yokumisa.
(7) Ukuma komzimba kulula, inqubo yokulingisa yinhle, futhi ububanzi bokusebenza bubanzi.
Ukungalungi kwe-valve yesango:
(1) Indawo yokuvala kulula ukulimaza izigxivizo ezimbili ezixhumene nesihlalo sevalvu ngesikhathi kuvulwa noma kuvalwa, futhi kuba khona ukungqubuzana phakathi kwalezi zimpawu ezimbili, okulula ukuzilimaza, kuthinta ukusebenza nempilo yesevisi ye uphawu, futhi kunzima ukunakekela.
(2) Isikhathi sokuvula nokuvala side, futhi ukuphakama kukhulu.Ngenxa yokuthi i-valve yesango kufanele ivule ngokugcwele noma ivalwe ngokugcwele lapho ivula futhi ivala, ukushaywa kwesango kukhulu, futhi isikhala esithile siyadingeka ukuze kuvulwe, futhi ubukhulu obuphelele buphezulu, futhi isikhala sokufaka sikhulu.
(3) Amavalvu esango anesakhiwo esiyinkimbinkimbi ngokuvamile anezindawo ezimbili zokuvala, ezikhulisa ukucutshungulwa, ukugaya kanye nokugcinwa.Kunezingxenye ezinzima kakhulu, ukukhiqiza nokunakekela kunzima kakhulu, futhi izindleko ziphakeme kunalezo zamavalvu embulunga.
Ububanzi be-valve yesango buyancipha:
Uma ububanzi bephaseji emzimbeni we-valve buhlukile (ngokuvamile ububanzi besihlalo se-valve buncane kunobubanzi bokuxhuma kwe-flange), kubizwa ngokuthi i-diameter shrinkage.
Ukuncipha kobubanzi kunganciphisa ubukhulu bezingxenye, kunciphise amandla adingekayo ekuvuleni nasekuvaleni, futhi kwandise ububanzi bokusetshenziswa kwezingxenye.Kodwa ngemva kokuba i-diameter iyancipha.Ukulahlekelwa ukumelana noketshezi kuyanda.
Ngaphansi kwezimo ezithile zokusebenza eminyangweni ethile (njengamapayipi kawoyela emkhakheni we-petroleum), amavalvu anobubanzi obuncishisiwe awavunyelwe.Ngakolunye uhlangothi, ukunciphisa ukulahlekelwa ukumelana kwepayipi, futhi ngakolunye uhlangothi, ukugwema izithiyo ekuhlanzweni kwemishini kwepayipi ngemva kokuncipha kobubanzi.
Ukufakwa nokugcinwa kwe-valve yesango kufanele kunake lezi zindaba ezilandelayo:
1. Amasondo esandla, izibambo kanye nezindlela zokudlulisa azivunyelwe ukuthi zisetshenziselwe ukuphakamisa, futhi ukushayisana akuvunyelwe ngokuqinile.
2. I-valve yesango eliphindwe kabili kufanele ifakwe ngokuqondile (okungukuthi, isiqu se-valve sisendaweni eqondile futhi isondo lesandla liphezulu).
3. I-valve yesango ene-bypass valve kufanele ivulwe ngaphambi kokuvula (ukulinganisa umehluko wokucindezela phakathi kokungena nokuphuma nokunciphisa amandla okuvula).
4. I-valve yesango enomshini wokudlulisa kufanele ifakwe ngokusho kwebhukwana lomkhiqizo.
5. Uma i-valve ivame ukuvulwa futhi ivaliwe, gcoba okungenani kanye ngenyanga.
I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.
