Iivalvu zebhabhathane zisetyenziswa kakhulu ekunikezelweni kwamanzi, ekulungisweni kwamanzi amdaka, nasekunyangweni ngamachiza. Ngenxa yokuba zinoyilo olulula, zisebenzisa izixhobo kakuhle, zincinci, kwaye zingabizi kakhulu.
Ukufakwa kweevalvu ngendlela efanelekileyo kuqinisekisa ukusebenza kakuhle kunye nobude bexesha. Ngaphambi kokufaka ivalvu yebhabhathane, kufuneka kuqondwe inkqubo yokufaka.Ngexesha lokufakwa, kufuneka ulandele amanyathelo okhuseleko.
1. Uyifaka njani ivalvu yebhabhathane kumbhobho?
a)Izixhobo eziyimfuneko
Ukufakela ivalvu yebhabhathane kufuna izixhobo ezahlukeneyo ukunceda.
-Ii-Wrenches ziqinisa iibholiti.
-Ii-torque wrenches zijonga ukuba ufakelo lukwinqanaba elifanelekileyo le-torque.
-Izikrufu ziqinisa iindawo ezincinci.
-Izicucu zemibhobho zenza iindawo zokufakelwa kweevalvu zebhabhathane.
-Iiglavu zokhuseleko kunye neeglasi zeglasi zithintela iingozi ezinokubakho.
-Umgca womgangatho kunye nomgca wombhobho: Qinisekisa ukuba ivalvu yebhabhathane ifakwe kwicala elifanelekileyo.
b) Izixhobo ezifunekayo
-Kufuneka izinto ezithile xa kufakelwa.
-Iigaskets zivala kakuhle ivalvu yebhabhathane kunye neflange.
-Iibholthi kunye neenati ziqinisa ivalvu yebhabhathane kumbhobho.
-Izinto zokucoca zisusa inkunkuma kumbhobho kunye nemiphezulu yeevalvu eyenziwe ngexesha lokufakelwa.
2. Amanyathelo Okulungiselela
Ukuhlola iValve yeButterfly
-Ukuhlola ivalvu yebhabhathane ngaphambi kokuba ifakelwe linyathelo elibalulekileyo. Umenzi ujonga ivalvu nganye yebhabhathane ngaphambi kokuba ithunyelwe. Nangona kunjalo, iingxaki zisenokubakho.
-Hlola ivalvu yebhabhathane ukuba akukho monakalo okanye iziphene ezibonakalayo.
-Qinisekisa ukuba idiski yevalvu ijikeleza ngokukhululekileyo kwaye ayibambeki.
-Qinisekisa ukuba isihlalo sevalvu asiguquki.
-Jonga ukuba ubungakanani bevalvu kunye noxinzelelo ziyahambelana neenkcukacha zombhobho.
Lungisa iNkqubo yeMibhobho
Okubaluleke njengokuhlola ivalvu yebhabhathane kukuhlola umbhobho.
-Coca umbhobho ukuze ususe umhlwa, inkunkuma kunye nezinto ezingcolisayo.
-Jonga ulungelelwaniso lweeflanges zombhobho odibanisayo.
-Qinisekisa ukuba iiflanges zigudile kwaye zithe tyaba ngaphandle kwee-burrs.
-Qinisekisa ukuba umbhobho ungaxhasa ubunzima bevalvu yebhabhathane, ngakumbi kwiivalvu ezinkulu. Ukuba akunjalo, sebenzisa ibracket ekhethekileyo.
3. Inkqubo yoFakelo
a) Ukubeka iValve yeButterfly
Beka ivalvu yebhabhathane ngokuchanekileyo kwipayipi.
Idiski yevalvu ivuleke kancinci ukuze ingayonakalisi yona okanye isihlalo xa ucinezela. Ukuba kuyimfuneko, sebenzisa iflange ekhethekileyo eyenzelwe iivalvu zebhabhathane zohlobo lwe-wafer. Idiski yevalvu ivuleke kancinci ukuze ingayonakalisi idiski yevalvu okanye isihlalo sevalvu xa ucinezela isihlalo sevalvu.
Jonga indlela ojongwa ngayo
Qinisekisa ukuba ivalvu yebhabhathane ifakwe kwindawo eyiyo.
Iivalvu zebhabhathane ezisembindini zihlala ziivalvu zebhabhathane ezibhekisa kwicala elinye. Iivalvu zebhabhathane ezinqamlezileyo zihlala zibhekisa kwicala elinye ngaphandle kokuba kufuneka ngenye indlela. Indlela yokuhamba kwesixhobo kufuneka ihambelane notolo olukwi-valve body, ukuze kuqinisekiswe ukuba isihlalo sevalvu siyavalwa.
Ukulungisa ivalvu yebhabhathane
Faka iibholithi kwimingxuma yeflange yevalvu yebhabhathane kunye nombhobho. Qinisekisa ukuba ivalvu yebhabhathane ithambile kunye nombhobho.Emva koko, ziqinise ngokulinganayo.
Ukuqinisa iibholithi ngendlela yenkwenkwezi okanye inkwenkwezi enqamlezileyo (oko kukuthi, ethe tyaba) kunokusasaza uxinzelelo ngokulinganayo.
Sebenzisa isikrufu se-torque ukufikelela kwi-torque echaziweyo yebholthi nganye.
Kuphephe ukuqinisa kakhulu, kungenjalo kuya konakalisa ivalvu okanye iflange.
Qhagamshela isixhobo sokuncedisa i-actuator actuator
Qhagamshela umbane kwintloko yombane. Kwakhona, qhagamshela umthombo womoya kwintloko yomoya.
Qaphela: I-actuator ngokwayo (isiphatho, izixhobo ze-worm, intloko yombane, intloko ye-pneumatic) ilungisiwe kwaye yalungiswa kwi-valve yebhabhathane ngaphambi kokuba ithunyelwe.
Uhlolo lokugqibela
-Jonga ukuba isitywino sevalvu yebhabhathane kunye nombhobho zineempawu zokungahambi kakuhle okanye umonakalo.
-Qinisekisa ukuba ivalvu isebenza kakuhle ngokuyivula nokuvala ivalvu izihlandlo ezininzi. Ingaba idiski yevalvu inokujikeleza ngokukhululekileyo ngaphandle kokuphazanyiswa okanye ukuxhathisa okugqithisileyo.
-Jonga zonke iindawo zoqhagamshelo ukuze ubone ukuba azivuzi na. Ungenza uvavanyo lokuvuza ngokucinezela yonke ipayipi.
-Yenza naluphi na uhlengahlengiso olufunekayo ukuqinisekisa ukusebenza kakuhle.
Ukusombulula iingxaki eziqhelekileyo
Ivalvu yebhabhathane ayivuli okanye ayivali kakuhle: Jonga izinto ezivala umbhobho. Kwakhona, jonga i-voltage yamandla e-actuator kunye noxinzelelo lomoya.
Ukuvuza xa kuqhagamshelwa: Jonga ukuba umphezulu weflange yombhobho awulingani na. Kwakhona, jonga ukuba iibholithi ziqiniswe okanye zikhululekile ngokulinganayo na.
Ukufakwa nokugcinwa ngokufanelekileyo kuqinisekisa ukuba ivalvu yebhabhathane isebenza ngokufanelekileyo kwiindlela ezahlukeneyo zokusebenza. Inkqubo yokufakela ivalvu yebhabhathane ibandakanya amanyathelo aliqela abalulekileyo. Ukucoca ngaphambi kokufakela, ukulungelelanisa ngokufanelekileyo, ukulungisa kunye nokuhlolwa kokugqibela kuqinisekisa ukusebenza kakuhle. Funda ngononophelo kwaye ulandele la manyathelo ngaphambi kokuba uqale ukufakela. Ukwenza njalo kunokuthintela iingxaki kunye neengozi.
Kaloku kukho intetho yakudala yesiTshayina ethi "ukulola imela akulibazisi ukugawula iinkuni."
