Valiva y’amasannyalaze (electromagnetic valve) kye kyuma ekikozesa empalirizo y’amasannyalaze okufuga okutambula kw’amazzi oba ggaasi. Okusinga kikolebwa omubiri gwa valve, valve core, electromagnetic coil, ne spring etc.
Koyilo ya magineeti bw’efuna amaanyi, ekifo kya magineeti kikolebwa, ekivaako omusingi gwa vvaalu okusikiriza oba okugobwa empalirizo ya magineeti, bwe kityo ne kifuga obulagirizi bw’okukulukuta n’embiro z’ekisengejja.
Valiva za Solenoid .zikozesebwa nnyo mu nnimiro nga enkola z’okufuga mu ngeri ey’otoma, okufulumya amakolero, eddagala eriweweeza ku mafuta, n’ebirala birina ebirungi ebiri mu nsengeka ennyangu, sipiidi y’okuddamu amangu, n’okwesigamizibwa okw’amaanyi.
Pneumatic solenoid valves zirina engeri nnyingi n’ebifo okusinziira ku mirimu gyazo n’ebyetaago byabwe.
Waliwo bibiri-okuteeka ebibiri-engeri, bibiri-okuteeka ebisatu-engeri, bbiri-okuteeka ebitaano -engeri, bbiri-okuteeka 4-way ne solenoid valves. (Bbiri-Ekifo Ekitaano-Way ne bbiri-Ekifo eky'okuna-ekwongera okugabanyizibwamu okufuga okw'obusannyalazo okumu n'ebika by'okufuga eby'obusannyalazo ebiri.)
Kya lwatu, ezisinga okuba ennyangu era ezisinga okukozesebwa ze zino ebbiri-okuteeka ssatu-ay solenoid valve ne two-okuteeka five-Way solenoid valve. Ekifo ekisatu-okuteeka valuva ya solenoid ey’okuyisaamu (way solenoid valve) esaana okukozesebwa nga ssiringi (actuator) yeetaaga okuyimirira wakati.
"Okuyita mu" ne "ekifo" ndowooza nkulu za pneumatic reversing solenoid valves.
"On" ne "position" ez'enjawulo zikola ebika eby'enjawulo ebya pneumatic reversing solenoid valves.
SO-eyitibwa "bbiri-vaalu y'ekifo" ne "valuku ssatu-okuteeka" zitera okutegeeza nti omusingi gwa vvaalu ya vvaalu y'okufuga obulagirizi gulina ebifo bibiri oba bisatu eby'enjawulo ebikola.
SO-eyitibwa "bbiri-Valiva y'ekkubo", "kusatu-ay valve" ne "Four-Way valve" zitegeeza ensengekera ebbiri, ssatu oba nnya ku mubiri gwa vvaalu ya vvaalu efugira obulagirizi etakwatagana naye nga zisobola okuyungibwa ku payipu za woyiro oba ggaasi ez'enjawulo mu nkola. Layini za woyiro/ggaasi ez’enjawulo zisobola okuwuliziganya n’ebifo "ebiwerako" mu maaso okuyita mu kuggulawo n’okuggalawo omukutu gwa vvaalu ng’omusingi gwa vvaalu gutambula. Olina okulaba working states mmeka valve eno erina okwogera ebifo bimeka. Singa wabaawo obubonero bw’ebitundu by’omukka, kijja kuba kyangu okutegeera. Ku kabonero, omuwendo gwa square (nga guliko obusaale oba t-ennyiriri munda) ezikiikirira omubiri gwa vvaalu gwe muwendo gw’ebifo.
"Jitong" mu kitundu ekisembayo ekiikirira omuwendo gw'ensonga ku emu ku square (ensonga ezikwatagana ne layini y'obusaale ne layini ya T), nga eno ye Jitong.
Amakulu g’obubonero obulaga okutwalira awamu gali bwegati:
(1) Kozesa bbokisi okulaga embeera y’okukola kwa vvaalu. Omuwendo gwa boxes gulaga omuwendo gwa "ebifo".
(2) Obusaale obuli munda mu kibokisi bulaga nti ekiyungo kya woyiro kiyungiddwa, naye obulagirizi bw’obusaale tebutegeeza nti bulaga obulagirizi obwennyini obw’okukulukuta kw’amazzi.
(3) Obujulizi "┻" oba "┳" mu kibokisi bulaga nti ekitundu kizibiddwa;
(4) Omuwendo gwa interfaces eziyungiddwa ebweru w'akabokisi gulaga obungi bwa "obuyungiddwa".
(5) Okutwalira awamu, omulyango oguyingira mu mafuta/empewo nga vvaalu eyungibwa ku layini oba empewo egaba amafuta g’enkola ekiikirira ennukuta p. Omukutu gwa ggaasi ogw’amafuta/okudda emabega nga vvaalu eyungibwa ku layini ya layini ya woyiro/gaasi ey’enkola ekiikirira T (oluusi O). Omukutu gwa woyiro/empewo vvaalu gy’eyungibwa ku actuator eragibwa A, B, n’ebirala Oluusi ekozesebwa ku bubonero obulaga ebifaananyi eby’amafuta agakulukuta.
(6) Valiva ezifuga obulagirizi zonna zirina ebifo bibiri oba okusingawo ebikola, ekimu ku byo kye kifo ekya bulijjo, kwe kugamba, ekifo omusingi gwa vvaalu we gubeera nga tegukolebwako maanyi ga kukola.
Ekifo ekiri wakati mu kabonero k’ekifaananyi kye kifo ekya bulijjo ekya vvaalu y’ekifo essatu-. Valiva y’ekifo ebbiri-ekozesa sseppulingi etwala embeera y’okuyita munda mu kibokisi okumpi ne sseppulingi ng’ekifo kyayo ekya bulijjo.
Nga okola ekifaananyi ky’enkola, ekiyungo kya woyiro/ggaasi okutwalira awamu kisaana okuyungibwa ku kifo ekya bulijjo ekya vvaalu efugira endagiriro. Omuwendo gw’ebifo gutegeeza omuwendo gw’embeera z’emirimu eza vvaalu. Omuwendo gw’embeera ezikola gwe muwendo gw’ebifo. Omuwendo gwa digito mu kabonero akakwatagana akalaga square y’emu.
"---ekifo?" kitegeeza omuwendo gw’ensonga mu emu ku bubonero bw’ebifaananyi obukwatagana ne square: layini y’obusaale ne T. Enkomerero ebbiri eza layini y’obusaale ziba nsonga bbiri, ate T ekiikirira ensonga emu.
Obulagirizi bw’akasaale bulaga obulagirizi bw’okukulukuta kwa ggaasi mu kkubo lya ggaasi. Akasaale ak’enjuyi ebbiri kalaga nti omukka guyinza okukulukuta mu njuyi zombi.
T eraga nti oluguudo luno luzibiddwa.
Ebibiri-Ekifo eky'okusatu-Ekkubo (1 intake, 1 exhaust, 1 exhaust) .
Ebibiri-Ekifo Ekitaano-Ekkubo (1 intake, 2 Exhaust, 2 Exhaust)
Okutwalira awamu, ekisenge ky'empewo kikiikirira "P", omukutu gw'omukka ogufuluma nga "R" ne "S" (ku ludda lwe lumu n'omulyango gw'empewo), n'emikutu gy'empewo egyayungibwa ku actuator nga "A" ne "B".
Okutwalira awamu, valve za solenoid zirina ebifo bibiri oba okusingawo ebikola. Ekimu ku byo y’embeera eya bulijjo.
Ekifo ekya bulijjo kitegeeza ekifo ky’omusingi gwa vvaalu bwe gutakolebwako maanyi ga masanyalaze (ekibokisi ekiri okumpi n’enkomerero ya sseppulingi kiragibwa mu kifaananyi).
Ekituufu:
Ekifaananyi kino wammanga kiraga NC nga vvaalu ya solenoid eya bulijjo eggaddwa Q(bwe kitassibwako amasannyalaze, ekiweebwayo kya ggaasi kisalibwa).
Mu kifaananyi kino wammanga, NO ekiikirira vvaalu ya solenoid eggule eya bulijjo Q(gaasi ekulukuta nga tefunye maanyi ku).
Solenoid valve bwe yeetaaga okutandika okumala ebbanga eddene ate nga ekiseera ky’okuggulawo ekigenda mu maaso kiwanvu nnyo okusinga ekiseera ky’okuggalawo, kirungi okulonda vvaalu ya solenoid eggule eya bulijjo.
Valiva ya solenoid bw’etera okukyusakyusa wakati w’okuggulawo n’okuggalawo, oba ekiseera ky’okuggulawo kiba kimpi, oba enjawulo y’obudde wakati w’okuggulawo n’okuggalawo si nkulu, vvaalu ya solenoid eya bulijjo eggaddwa erina okulondebwa .
Akabonero mu kifaananyi kino wammanga kalaga nti vvaalu ya solenoid ya butereevu-okukola .
Akabonero mu kifaananyi kino wammanga kalaga nti vvaalu ya solenoid ye pilot-ekika ekiddukanyizibwa .
Five-Way kitegeeza nti waliwo emikutu etaano egy'okuyingiza empewo .
Ekimu ku byo kiyungibwa ku nsibuko ya ggaasi.
Ebibiri biyungibwa ku kisenge ky’empewo n’okufuluma kw’ekisenge ky’empewo eky’ebweru ekya ssilindala ey’emirundi ebiri-ekola.
Ebifo ebibiri ebiyingira mu mpewo n’ebifo ebifulumya empewo biyungibwa ku kisenge ky’empewo ekiri munda.
Enkola ey’enjawulo ey’okukola esobola okujulizibwa ku ya double-acting pneumatic actuator. Mu ngeri y’ekkubo ly’empewo (oba ekkubo ly’amazzi) :
Ebibiri-ebisatu-ay solenoid valve erina empewo emu (olw’okuyunga ku nsibuko y’empewo), empewo emu efulumya empewo (olw’okuwa ensibuko y’empewo eri ebyuma ebigendererwa), n’ekifo ekimu eky’empewo (ebiseera ebisinga nga kirimu ekiwujjo; singa oluyoogaano terubeera kyeraliikiriza, era lusobola okulekebwawo).
Ebyo ebibiri-okuteeka five-Way solenoid valve erina ekituli kimu eky’empewo ekiyingira (eyungiddwa ku nsibuko y’empewo ey’okuyingiza), ekituli kimu eky’empewo eky’omu maaso eky’okukola n’ekituli kimu eky’empewo eky’okudda emabega (respectively providing one forward and one reverse action air source for the target equipment), ekituli kimu eky’omu maaso eky’okukola n’ekituli kimu eky’okudda emabega (nga muffler eteekeddwamu).
Ku byuma ebitono ebifuga otomatiki, payipu z’empewo ez’omu kapiira mu makolero nga zirina obuwanvu bwa 8 ku 12 okutwalira awamu zirondebwa ku payipu z’empewo.
Mu kwogera mu masanyalaze, bbiri-okuteeka valve ssatu-okutwalira awamu zifugibwa-zifugibwa (kwe kugamba, emu-, ate bbiri-okuteeka valve ttaano-ezo eziyitibwa solenoid zitera okuba emirundi ebiri-ezifuga (kwe kugamba, emirundi ebiri-coil).
Okutwalira awamu emitendera gya vvulovumenti ya koyilo giri DC24V, AC220V, n’ebirala.
Ebibiri -Ebifo bisatu-ay solenoid valves zigabanyizibwamu ebika bibiri: normally closed and normally open.
Ekika kya bulijjo ekiggaddwa kitegeeza embeera ng’ekkubo ly’empewo likutuddwa nga koyilo terina maanyi.
Ekika ekiggule ekya bulijjo kitegeeza embeera ng’omukutu gw’empewo guggule nga koyilo terina maanyi.
Enkola y’okukola ey’ebibiri-Ekifo eky’okutaano-Way double efugirwa amasannyalaze solenoid valve:
Coil ya forward action bweba efunye amaanyi, forward action airway eyungibwa (waliwo empewo ku forward action air outlet). Ne bwe kiba nti koyilo y’ekikolwa eky’omu maaso ye de-ewereddwa amaanyi, omukutu gw’empewo ogw’omu maaso gusigala nga guyungiddwa era gujja kusigala bwe gutyo okutuusa nga koyilo y’ekikolwa eky’okudda emabega efunye amaanyi.
Koyilo y’ekikolwa eky’okudda emabega bw’efuna amaanyi, omukutu gw’empewo ogw’okudda emabega guyungibwa (waliwo empewo mu kinnya ky’empewo ekya koyilo y’ekikolwa eky’okudda emabega). Ne bwe kiba nti koyilo y’ekikolwa eky’okudda emabega (reverse action coil) efuuse-efunye amaanyi, omukutu gw’empewo ogw’okudda emabega gusigala nga guyungiddwa era gujja kusigala bwe gutyo okutuusa nga koyilo y’ekikolwa eky’omu maaso efunye amaanyi. Kino kyenkanawa ne "self-okuzibikira".
Okusinziira ku ngeri eno ey’ebibiri-okuteeka five-Way double electric control solenoid valve, nga okola dizayini ya electromechanical control circuit oba programming PLC, kyetaagisa kyokka okuleka solenoid valve coil okukola for 1 to 2 seconds. Kino kiyinza okukuuma coil ya solenoid valve obutayonooneka mangu.
