Izinzuzo ze-valve yesango:
(1) Ukumelana noketshezi okuncane Ngenxa yokuthi isiteshi sangaphakathi esiphakathi somzimba we-valve yesango siqondile, i-medium ayishintshi indlela yokugeleza kwayo lapho igeleza nge-valve yesango, ngakho ukumelana noketshezi kuncane.
(2) I-torque yokuvula nokuvala incane, kanti ukuvulwa nokuvala konga kakhulu abasebenzi. Ngenxa yokuthi isiqondiso sokunyakaza kwesango siqonde ngqo esiya ekuqondeni kokugeleza okuphakathi lapho ivalvu yesango ivulwa futhi ivalwa, ukuvulwa nokuvalwa kwevalvu yesango konga kakhulu abasebenzi uma kuqhathaniswa nevalvu yokuma.
(3) Isiqondiso sokugeleza kwe-medium asinqunyelwe, futhi i-medium ingageleza kunoma iyiphi indlela kusuka ezinhlangothini zombili ze-valve yesango ngaphandle kokuphazamisa ukugeleza nangaphandle kokunciphisa ingcindezi, futhi injongo yokusetshenziswa ingafezwa. Ifaneleka kakhulu kumapayipi lapho isiqondiso sokugeleza kwe-medium singashintsha khona.
(4) Ubude besakhiwo bufushane ngoba isango levalvu yesango libekwe phezulu emzimbeni wevalvu, kanti idiski yevalvu yevalvu yokumisa ibekwe ngokuvundlile emzimbeni wevalvu, ngakho ubude besakhiwo bufushane kunobevalvu yokumisa.
(5) Ngokusebenza kahle kokuvala, indawo yokuvala ayigugi kakhulu uma ivuliwe ngokuphelele.
(6) Uma ivuliwe ngokuphelele, ukuguguleka kwendawo yokuvala yi-medium yokusebenza kuncane kunokwe-valve yokuma.
(7) Ukuma komzimba kulula kakhulu, inqubo yokubumba ilungile, futhi ububanzi bokusetshenziswa bubanzi.
Okubi nge-valve yesango:
(1) Indawo yokuvala kulula ukulimaza izivalo ezimbili ezithintana nesihlalo se-valve ngesikhathi sokuvulwa nokuvalwa, futhi kukhona ukungqubuzana okuhlobene phakathi kwezivalo ezimbili, okulula ukuzonakalisa, okuthinta ukusebenza kanye nokuphila kwenkonzo yesivalo, futhi okunzima ukukugcina.
(2) Isikhathi sokuvula nokuvala side, futhi ukuphakama kukhulu. Ngenxa yokuthi ivalvu yesango kumele ivulwe ngokugcwele noma ivalwe ngokuphelele lapho kuvulwa futhi kuvalwa, ukushaywa kwesango kukhulu, futhi kudingeka isikhala esithile ukuze kuvulwe, futhi usayizi jikelele uphakeme, futhi isikhala sokufakwa sikhulu.
(3) Amavalvu esango anesakhiwo esiyinkimbinkimbi ngokuvamile anezindawo ezimbili zokuvala, okwandisa ukucubungula, ukugaya kanye nokunakekela. Kunezingxenye ezinzima kakhulu, ukukhiqiza kanye nokunakekela kunzima kakhulu, futhi izindleko ziphakeme kunezamavalvu embulunga.
Ububanzi bevalvu yesango buyancipha:
Uma ububanzi bendlela emzimbeni wevalvu buhlukile (ngokuvamile ububanzi esihlalweni sevalvu buncane kunobubanzi bokuxhumeka kweflange), kubizwa ngokuthi ukuncishiswa kobubanzi.
Ukuncipha kobubanzi kunganciphisa usayizi wezingxenye, kunciphise amandla adingekayo ekuvuleni nasekuvaleni, futhi kwandise ububanzi bokusetshenziswa kwezingxenye. Kodwa ngemva kokuncipha kobubanzi. Ukulahlekelwa ukumelana noketshezi kuyanda.
Ngaphansi kwezimo ezithile zokusebenza eminyangweni ethile (njengemipayipi kawoyela emkhakheni wephethiloli), amavalvu anobubanzi obuncishisiwe awavunyelwe. Ngakolunye uhlangothi, ukunciphisa ukulahlekelwa ukumelana kwepayipi, kanti ngakolunye uhlangothi, ukugwema izithiyo ekuhlanzweni kwepayipi ngemishini ngemva kokuncipha kobubanzi.
Ukufakwa nokugcinwa kwevalvu yesango kufanele kuqaphele izinto ezilandelayo:
1. Amasondo esandla, izibambo kanye nezindlela zokudlulisa azivunyelwe ukusetshenziswa ekuphakamiseni, futhi ukushayisana akuvunyelwe ngokuphelele.
2. Ivalvu yesango eliphindwe kabili kufanele ifakwe iqonde phezulu (okungukuthi, isiqu sevalvu sisesimweni esiqondile kanti isondo lesandla liphezulu).
3. Ivalvu yesango enevalvu yokudlula kufanele ivulwe ngaphambi kokuvula (ukulinganisela umehluko wokucindezela phakathi kokungena kanye nokukhipha futhi kuncishiswe amandla okuvula).
4. I-valve yesango enendlela yokudlulisa kufanele ifakwe ngokwencwadi yemiyalelo yomkhiqizo.
5. Uma ivalvu ivame ukuvulwa futhi ivalwe, gcoba okungenani kanye ngenyanga.
INortech ingenye yabakhiqizi bama-valve ezimboni abahamba phambili eShayina abanesitifiketi sekhwalithi se-ISO9001.
