Valiva kye kiyungo kya payipu ekikozesebwa okuggulawo n’okuggala payipu, okufuga obulagirizi bw’okukulukuta, okulungamya n’okufuga ebipimo (ebbugumu, puleesa n’omutindo gw’okukulukuta) eby’ekintu ekitambuzibwa. Okusinziira ku nkola yaayo, esobola okwawulwamu vvaalu eziggalawo, .vvaalu z’okukebera, okulungamya vvaalu, n’ebirala.
Valiva ze bitundu ebifuga mu nkola z’okutambuza amazzi, ebirina emirimu gy’okuggala, okulungamya, okukyusa, okuziyiza okudda emabega, okutebenkeza puleesa, okukyusa oba okukendeeza ku puleesa y’okukulukuta. Valiva z’enkola z’okufuga amazzi zitandikira ku vvaalu ezisinga okuba ennyangu eziggalawo okutuuka ku vvaalu ezisinga obuzibu ezikozesebwa mu nkola z’okufuga mu ngeri ey’otoma.
Valiva zisobola okukozesebwa okufuga okutambula kw’ebika by’amazzi eby’enjawulo nga empewo, amazzi, omukka, emikutu egy’enjawulo egy’okukulukuta, ebikuta, amafuta, ebyuma eby’amazzi n’emikutu egy’amasannyalaze. Okusinziira ku kintu kino, vvaalu nazo zigabanyizibwamuvvaalu z’ekyuma ekisuuliddwa, vvaalu z’ekyuma ekisuuliddwa, vvaalu z’ekyuma ekitali kizimbulukuse (201, 304, 316, n’ebirala), vvaalu z’ekyuma kya chrome-molybdenum, vvaalu z’ekyuma kya chromium-molybdenum vanadium, vvaalu z’ekyuma ekibiri, vvaalu z’obuveera, vvaalu ezitali za mutindo ezikoleddwa ku mutindo, n’ebirala.
Okugabanya
Nga tuyita mu nkola n’enkozesa
(1) Valiva eggalawo
Valiva ey’ekika kino ekozesebwa okuggulawo n’okuggalawo. Kiteekebwa enkalakkalira mu kifo ekiyingira n’okufuluma kw’ensibuko z’ennyogovu n’ebbugumu, okuyingira n’okufuluma kw’ebyuma, ne layini y’amatabi ga payipu (nga mw’otwalidde n’ebisitula), era esobola n’okukozesebwa nga vvaalu efulumya amazzi ne vvaalu efulumya empewo. Valiva eziggalawo eza bulijjo mulimuvvaalu z’emiryango, vvaalu za globe, vvaalu z’omupiira ne vvaalu za butterfly.
Valiva z’emiryangoesobola okugabanyizibwamu omuggo omuggule n’omuggo omuddugavu, ennume emu n’embuzi bbiri, ennume ento (wedge ram) ne ennume ey’ekika kya parallel, n’ebirala Obunywevu bwa vvaalu y’omulyango si bulungi, era kizibu okuggulawo vvaalu y’omulyango eya dayamita ennene; Enkula y’omubiri gwa vvaalu ntono okumpi n’oludda lw’okutambula kw’amazzi, okuziyiza okukulukuta kutono, ate span ya dayamita ey’erinnya eya vvaalu y’omulyango nnene.
Okusinziira ku ndagiriro y’okukulukuta kw’ekisengejjero, vvaalu ya globo egabanyizibwamu ebika bisatu: ekika ekiyita obutereevu, ekika kya nkoona entuufu n’ekika ky’okukulukuta obutereevu, era waliwo emiggo egy’olubeerera n’emiggo egy’ekizikiza. Okunyweza okuggalawo kwa vvaalu ya globe kusinga okwa vvaalu ya ggeeti, omubiri gwa vvaalu muwanvu, okuziyiza okukulukuta kunene, ate obuwanvu obusinga obunene obw’erinnya ye DN200.
Spooli ya vvaalu y’omupiira gwe mupiira oguggule. Ekikolo kya vvaalu ekikola ku pulati kifuula omupiira okugguka nga gutunudde mu kisenge kya payipu, era guggalwa mu bujjuvu nga gukyuse 90°. Valiva y’omupiira erina omulimu gw’okutereeza ogumu era eggalawo bulungi.
Ekyuma ekikuba...vvaalu y’ekiwujjoye disiki eyeetooloovu eyeetooloola okuyita ku kikondo ekyesimbye eky’ekisiki kya payipu ekyesimbye. Ennyonyi ya vvaalu plate bw’ekwatagana n’ekisiki kya payipu, eba eggule mu bujjuvu; Ennyonyi ya ram bweba nga yeesimbye ku kisenge kya payipu, eggalwa mu bujjuvu. Obuwanvu bw’omubiri gwa vvaalu ya butterfly butono, obuziyiza okukulukuta butono, ate bbeeyi eri waggulu okusinga eya vvaalu za gate ne vvaalu za globe.
(2) Kebera vvaalu
Ekika kya vvaalu kino kikozesebwa okuziyiza okudda emabega kw’ekisengejjero, era kikozesa amasoboza g’amazzi gennyini ag’ekiddukano okweggulawo n’okuggalawo mu ngeri ey’otoma nga gakulukuta mu kkubo ery’ekikontana. Okuyimirira ku kifo ppampu efuluma, omutego we gufulumira, n’ebifo ebirala amazzi we gadda emabega we gatakkirizibwa. Waliwo ebika bya check valve bisatu: ekika kya rotary opening, ekika ekisitula n’ekika kya clamp. Mu mbeera ya swing check valves, amazzi gasobola okukulukuta okuva ku kkono okudda ku ddyo yokka era gaggalawo otomatiki nga gakulukuta mu kkubo ery’ekikontana. Ku vvaalu ezikebera okusitula, ekisengejja kisitula waggulu okukola ekkubo ng’amazzi gakulukuta okuva ku kkono okudda ku ddyo, ate ekisiba kiggalwa nga kinywezeddwa ku ntebe ng’okukulukuta kukyusiddwa. Ku vvaalu y’okukebera (clamp-on check valve), amazzi bwe gakulukuta okuva ku kkono okudda ku ddyo, omusingi gwa vvaalu guggulwawo okukola ekkubo, era omusingi gwa vvaalu gunyigirizibwa ku ntebe ya vvaalu ne guggalwa ng’okukulukuta okudda emabega kukyusiddwa.
(3) Okulungamyavvaalu eziyitibwa valves
Enjawulo ya puleesa wakati w’emmanju n’emabega wa vvaalu nkakasa, era okuggulawo kwa vvaalu eya bulijjo bwe kukyuka mu bbanga eddene, omutindo gw’okukulukuta gukyuka kitono, era bwe gutuuka ku kifo ekimu ekiggule, omutindo gw’okukulukuta gukyuka nnyo, kwe kugamba, omulimu gw’okutereeza guba mubi. Valiva efugira esobola okukyusa stroke ya spool okukyusa resistance ya valve okusinziira ku direction n’obunene bwa signal, okusobola okutuukiriza ekigendererwa ky’okulungamya flow valve. Valiva ezifuga zaawulwamu vvaalu ezifuga mu ngalo ne vvaalu ezifuga otomatiki, era waliwo ebika bingi ebya vvaalu ezifuga mu ngalo oba otomatiki, era n’enkola yazo ey’okutereeza nayo ya njawulo. Valiva ezifuga otomatiki mulimu vvaalu ezifuga okukulukuta ezeekolera ne vvaalu ezifuga puleesa ya diferensi ezikola zokka.
(4) Okufuuwa empewo
Vacuum mulimu vacuum ball valves, vacuum baffle valves, vacuum inflation valves, pneumatic vacuum valves, n’ebirala Omulimu gwayo guli mu vacuum system, ekintu eky’enkola ya vacuum ekikozesebwa okukyusa obulagirizi bw’okutambula kw’empewo, okutereeza obunene bw’okutambula kw’empewo, okusala oba okuyunga payipu kiyitibwa vacuum valve.
(5) Ebika eby’ebigendererwa eby’enjawulo
Ebika by’ebigendererwa eby’enjawulo mulimu vvaalu z’embizzi, vvaalu z’okufulumya empewo, vvaalu ezifuuwa omukka, vvaalu z’okufulumya omukka, ebyuma ebisengejja n’ebirala.
Valiva efulumya omukka kitundu kya buyambi ekiteetaagisa mu nkola ya payipu, ekozesebwa nnyo mu bboyiyira, ebyuma ebifuuwa empewo, amafuta ne ggaasi, payipu ezigaba amazzi n’okufulumya amazzi. Kitera okuteekebwa ku buwanvu obulagira oba ku nkokola okuggyawo ggaasi ayitiridde mu payipu, okulongoosa enkola y’okukozesa payipu n’okukendeeza ku maanyi agakozesebwa.
Omupiira gwonna ogutuddevvaalu y’ekiwujjo, vvaalu y’omulyango, Y-stainer, vvaalu y’okutebenkeza, .wafer dual plate okukebera valveebibuuzo, osobola okutuukiriraValiva ya TWSfakitole. Era osobola okunyiga ku mukutu gwaffe ogwa yintaneeti https://www.tws-valve.com/ okumanya ebisingawo.
