Izivalo zebhabhathane zisetyenziswa kakhulu kubonelelo lwamanzi, ukucocwa kwamanzi amdaka, kunye nonyango lwekhemikhali.Ngenxa yokuba zinoyilo olulula, sebenzisa izixhobo kakuhle, zincinci, kwaye ziphantsi.
Ukufakwa kwe-valve ngokufanelekileyo kuqinisekisa ukusebenza kakuhle kunye nokuphila ixesha elide.Ngaphambi kokufaka i-valve butterfly, inkqubo yokufakela kufuneka iqondwe.Ngexesha lofakelo, nawe othandekayo kufuneka ulandele amanyathelo okhuseleko.
1. Indlela yokufaka ivalve yebhabhathane kumbhobho?
a)Izixhobo eziyimfuneko
Ukufakela ivalve yebhabhathane kufuna izixhobo ezahlukeneyo ukunceda.
-Izitshixo ziqinisa iibholithi.
-Izitshixo zetorque zijonga ukuba ngaba ufakelo lungaphakathi koluhlu lwetorque efanelekileyo.
-Izikrufu zikhusela iindawo ezincinci.
-Abasiki bemibhobho benza izithuba zofakelo lwevalvu yebhabhathane.
-Iiglavu zokhuseleko kunye neeglavu zithintela iingozi ezinokubakho.
-Inqanaba kunye nentambo yokulinganisa: Qinisekisa ukuba ivalve yebhabhathane ifakwe kwicala elichanekileyo.
b)Imathiriyeli efunekayo
-Izinto ezifunekayo zokufakelwa.
-Iigaskets zitywina ngokufanelekileyo ivalve yebhabhathane kunye neflange.
-Iibholiti kunye namantongomane zikhusela ivalve yebhabhathane kumbhobho.
-Izixhobo zokucoca zisusa i-debris kumbhobho kunye neendawo zevalve ezenziwe ngexesha lofakelo.
2. Amanyathelo okulungiselela
Ukuhlola iValve yeButterfly
-Ukuhlola ivalve yebhabhathane phambi kokufakwa linyathelo elibalulekileyo.Umenzi ujonga ivalve yebhabhathane nganye phambi kokuba ithunyelwe.Nangona kunjalo, iingxaki zisenokuvela.
-Hlola ivalve yebhabhathane kuwo nawuphi na umonakalo obonakalayo okanye iziphene.
-Qinisekisa ukuba i-disc yevalve ijikeleza ngokukhululekileyo kwaye ayibambekanga.
-Qinisekisa ukuba isitulo sevalvu sicocekile.
-Khangela ubungakanani bevalve kunye noxinzelelo oluhambelana nenkcazo yombhobho.
Lungiselela iNkqubo yePipeline
Kanye njengokuba kubaluleke njengokuhlola ivalve yebhabhathane kuhlola umbhobho.
-Coca umbhobho ukususa umhlwa, inkunkuma kunye nongcoliseko.
-Khangela ukulungelelaniswa kweeflange zombhobho wokudibanisa.
-Qinisekisa ukuba ii-flanges zigudile kwaye zithe tyaba ngaphandle kwe-burrs.
-Qinisekisa ukuba umbhobho ungabuxhasa ubunzima bevalve yebhabhathane, ingakumbi kwiivalvu ezinkulu.Ukuba akunjalo, sebenzisa isibiyeli esikhethekileyo.
3. Inkqubo yokuFakela
a)Ukubeka iValve yebhabhathane
Misa ivalve yebhabhathane ngokuchanekileyo kumbhobho.
Idiskhi yevalve ivuleleke kancinci ukunqanda ukuyonakalisa okanye isitulo xa ucudisa.Ukuba kuyimfuneko, sebenzisa i-flange ekhethekileyo eyenzelwe i-wafer-type butterfly valves.Idiskhi yevalvu ivuleke kancinane ukunqanda ukonakalisa idiski yevalvu okanye isitulo sevalvu xa ucofa isitulo sevalvu.
Jonga ukuqhelaniswa
Qinisekisa ukuba ivalve yebhabhathane ifakelwe ngendlela eyiyo.
Izivalo zebhabhathane zomgca ophakathi zidla ngokuba ziivalve zebhabhathane ezimacala omabini.Iivalvu zebhabhathane eccentric ziqhele ukubakho enye indlela ngaphandle kokuba kufunwa ngenye indlela.Indlela yokuhamba kwayo kufuneka ihambelane notolo olukumzimba wevalvu, ukuze kuqinisekiswe ukutywinwa kwesitulo sesivalo.
Ukulungisa ivalve yebhabhathane
Faka iibholithi kwimingxuma yeflange yevalve yebhabhathane kunye nombhobho.Qinisekisa ukuba ivalve yebhabhathane igungxulwe ngumbhobho.Emva koko, ziqinise ngokulinganayo.
Ukuqinisa iibholithi kwenkwenkwezi okanye kwenkwenkwezi enqamlezileyo (oko kukuthi, i-diagonal) ngendlela enokusasaza ngokulinganayo uxinzelelo.
Sebenzisa i-torque wrench ukufikelela kwitorque echaziweyo kwibholiti nganye.
Gwema ukugqithisa, ngaphandle koko kuya kulimaza i-valve okanye i-flange.
Qhagamshela isixhobo esincedisayo se-actuator
Xhuma unikezelo lwamandla kwintloko yombane.Kwakhona, qhagamshela umthombo womoya kwintloko ye-pneumatic.
Qaphela: I-activator ngokwayo (isibambo, igiya yeentshulube, intloko yombane, intloko ye-pneumatic) ilungisiwe kwaye yalungiswa kwivalve yebhabhathane phambi kokuthunyelwa.
Uhlolo lokugqibela
-Jonga ukuba isivalo sevalve yebhabhathane kunye nombhobho unazo naziphi na iimpawu zokungalungelelani kakuhle okanye umonakalo.
-Qinisekisa ukuba ivalve isebenza kakuhle ngokuvula nokuvala ivalve amaxesha amaninzi.Ingaba i-disc ye-valve inokujikeleza ngokukhululekileyo ngaphandle kokuphazamiseka okanye ukuchasana okugqithisileyo.
-Jonga zonke iindawo zoqhagamshelwano ukuba zivuza.Unokwenza uvavanyo lokuvuza ngokucinezela umbhobho wonke.
-Yenza naluphi na uhlengahlengiso oluyimfuneko ukuqinisekisa ukusebenza kakuhle.
Ukusombulula iingxaki eziqhelekileyo
Ivalve yebhabhathane ayivuleki okanye ivaleke kakuhle: Jonga izinto ezivale umbhobho.Kwakhona, jonga amandla ombane we-activator kunye noxinzelelo lomoya.
Ukuvuza kumdibaniso: Jonga ukuba umphezulu weflange wombhobho awulingani.Kwakhona, khangela ukuba iibholiti ziqiniswe ngokungalinganiyo okanye zikhululekile.
Ukufakwa kunye nokugcinwa ngokufanelekileyo kuqinisekisa ukuba i-valve ye-butterfly isebenza ngokufanelekileyo kwiintlobo ezahlukeneyo zezicelo.Inkqubo yokufakwa kwevalve yebhabhathane ibandakanya amanyathelo abalulekileyo aliqela.Ukucoca ngaphambi kokufaka, ukulungelelaniswa okufanelekileyo, ukulungiswa kunye nokuhlolwa kokugqibela kuqinisekisa ukusebenza kakuhle.Funda ngononophelo kwaye ulandele la manyathelo phambi kokuqalisa ufakelo.Ukwenjenjalo kunokuthintela iingxaki neengozi.
Ngapha koko, kukho intetho yakudala yamaTshayina ethi, “ukulola imela akukulibazisi ukugawula iinkuni.”
