Amavalvu aqhutshwa umoyaziyizingxenye ezibalulekile ezinqubweni ezahlukahlukene zezimboni, zilawula ngempumelelo ukugeleza koketshezi namagesi. Lawa ma-valve asebenzisaama-actuator omoyaukuvula nokuvala ngokuzenzakalelayo indlela yokusebenza, okuvumela ukulawulwa okunembile kokugeleza kanye nokucindezela. Kulesi sihloko, sizohlola izinhlobo ezahlukene zamavalvu aqhutshwa umoya, okuhlanganisa amavalvu ebhola aqhutshwa umoya, amavalvu ebhabhathane, amavalvu esango, amavalvu embulunga, namavalvu e-SDV, sigxile ezicini zawo ezihlukile kanye nezinhlelo zokusebenza.
Iyini ivalvu eqhutshwa umoya
I-valve ye-pneumatic actuator iyithuluzi elisebenzisa umoya ocindezelwe ukuze lisebenzise indlela ye-valve. I-actuator iguqula amandla emoyeni ocindezelwe abe ukunyakaza komshini, ivule noma ivale i-valve. Lolu hlobo lokuzenzakalela lubalulekile ezimbonini lapho ukusebenza ngesandla kungasebenzi noma kungaphephile, njengokucubungula amakhemikhali, uwoyela negesi, ukwelashwa kwamanzi, kanye nokukhiqiza.
Izinzuzo eziyinhloko zamavalvu asebenza ngomoya ukuthi ijubane lawo kanye nokuthembeka kwawo. Angasetshenziswa ngokushesha, okwenza afaneleke kakhulu ekusetshenzisweni okudinga izikhathi zokuphendula ngokushesha. Ngaphezu kwalokho, izinhlelo zomoya zivame ukuba lula futhi zingabizi kakhulu kunezinhlelo zikagesi noma ze-hydraulic, okwenza zithandwe ezindaweni eziningi zezimboni.
Izinhlobo ze-Pneumatic Actuators
1. I-valve yebhola yomoya
Amavalvu Ebhola Le-Actuator YomoyaZenzelwe idiski eyindilinga (ibhola) ukulawula ukugeleza koketshezi ngevalvu. Uma ibhola lijikeleza ama-degree angu-90, livumela noma livimbele ukugeleza koketshezi. Lawa mavalvu aziwa ngamakhono awo amahle okuvala kanye nokwehla okuncane kokucindezela, okwenza afaneleke ukusetshenziswa okubandakanya uketshezi olunomfutho ophezulu.
Ama-ball valve avame ukusetshenziswa embonini kawoyela negesi, ukuphakelwa kwamanzi kanye nokucubungula amakhemikhali. Ama-ball valve asebenza ngokushesha, ahlala isikhathi eside futhi ayisinqumo sokuqala sezinhlelo zokulawula ezivuliwe/ezivaliwe.
2. Ivalvu yebhabhathane yomoya
Amavalvu ebhabhathane asebenzisa idiski ejikelezayo ukulawula ukugeleza. Idiski ifakwe emgodleni futhi ingajikeleziswa ukuvula noma ukuvala ivalvu.Amavalvu ebhabhathane e-actuator yomoyaziwusizo kakhulu ekusetshenzisweni okudinga amazinga aphezulu okugeleza kanye nokwehla kwengcindezi okuphansi.
Lawa ma-valve alula futhi ancane, okwenza afaneleke kakhulu ekufakweni lapho isikhala silinganiselwe khona. Ngenxa yokusebenza kwawo kahle kakhulu kanye nokugcinwa okulula, asetshenziswa kabanzi ezinhlelweni ze-HVAC, ezimbonini zokuhlanza amanzi, kanye nasezimbonini zokucubungula ukudla.
3. I-valve yesango lomoya
Amavalvu esango aklanyelwe ukuhlinzeka ngendlela eqondile yokugeleza, okunciphisa ukulahleka kwengcindezi. Asebenza ngokuphakamisa isango lisuke endleleni yokugeleza, okuvumela ukugeleza okugcwele uma livuliwe.Amavalvu esango aqhutshwa umoyazivame ukusetshenziswa ezicelweni ezidinga ukuvalwa okuqinile, njengezinhlelo zamanzi kanye namapayipi kawoyela.
Nakuba ama-valve esango engafanele ukusetshenziswa kwe-throttling, asebenza kahle kakhulu ezimweni zokulawula ezivuliwe/ezivaliwe. Ukwakhiwa kwawo okuqinile kanye nekhono lokubekezelela ukucindezeleka okuphezulu kuwenza afanelekele ukusetshenziswa okuhlukahlukene kwezimboni.
4. I-valve yeglobhu ye-actuator yomoya
Ivalvu yomhlaba inomzimba oyindilinga futhi isetshenziselwa ukugoqa. Idiski ihamba ngokuqondile iqonde ohlangothini loketshezi, okuvumela ukulawulwa okunembile kokugeleza. Amavalvu embulunga aqhutshwa umoya avame ukusetshenziswa ezinhlotsheni lapho ukulawulwa kokugeleza kubaluleke kakhulu, njengezinhlelo zomusi kanye nokucubungula amakhemikhali.
Lawa ma-valve ahlinzeka ngokulawula ukugeleza okuhle kakhulu futhi afanele ukusetshenziswa komfutho ophezulu. Kodwa-ke, angaba nokwehla komfutho okuphezulu kunezinye izinhlobo zama-valve, okwenza angafaneleki ukusetshenziswa okudinga ukumelana okuncane.
5. Ivalvu ye-SDV (ivalvu yokuvala)
Ama-valve okuvala (ama-SDV) ayizinto zokuphepha ezibalulekile ezisetshenziswa ezimbonini ezahlukahlukene ukuvimbela ukugeleza kwezinto eziyingozi ngesikhathi sezimo eziphuthumayo noma ukulungiswa. Ama-valve e-SDV asebenza ngogesi aklanyelwe ukuvala ngokushesha nangokuphepha, ukuqinisekisa ukuthi ukugeleza kuyamiswa ngokushesha lapho kudingeka.
Lawa ma-valve avame ukusetshenziswa ezindaweni zikawoyela negesi, ezitshalweni zamakhemikhali, nakwezinye izindawo ezinobungozi obukhulu. Ukuthembeka kwawo kanye nesikhathi sokuphendula ngokushesha kuwenza abaluleke kakhulu ekugcineni ukuphepha kanye nokuhambisana nemithethonqubo yemboni.
Ukusetshenziswa kwe-Pneumatic Actuator Valve
Amavalvu asebenza ngomoya asetshenziswa emikhakheni eminingi ngenxa yokuguquguquka kwawo kanye nokusebenza kahle kwawo. Ezinye izinhlelo zokusebenza ezivamile zifaka:
- Ukucubungula AmakhemikhaliAmavalvu aqhutshwa umoya asetshenziswa ukulawula ukuhamba kwamakhemikhali kuma-reactor, ama-mixer kanye namathangi, ukuqinisekisa ukukala nokuxuba okunembile.
- Uwoyela negesi: Lawa ma-valve adlala indima ebalulekile ekulawuleni ukugeleza kukawoyela ongahluziwe, igesi yemvelo, kanye nemikhiqizo ehlanjululwe emapayipini nasezindaweni zokucubungula.
- Ukwelashwa Kwamanzi: Izitshalo zokwelapha amanzi zisebenzisa amavalvu aqhutshwa umoya ukulawula ukugeleza kwamanzi namakhemikhali asetshenziswa enkambisweni yokuhlanza.
- Izinhlelo ze-HVAC: Ezinhlelweni zokushisa, zokungenisa umoya, kanye nezokupholisa umoya, la ma-valve asiza ukulawula ukuhamba komoya kanye nokushisa, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwamandla kanye nenduduzo.
- Ukudla NeziphuzoAma-valve aqhutshwa umoya asetshenziswa ekucubungulweni kokudla ukuqinisekisa ukuphathwa okuphephile nokuphumelelayo kwezithako nemikhiqizo.
Ekuphetheni
Amavalvu aqhutshwa umoyaziyisici esibalulekile sezinqubo zezimboni zanamuhla, ezihlinzeka ngokulawula okuthembekile nokuphumelelayo kokugeleza koketshezi kanye negesi. Amavalvu aqhutshwa umoya atholakala ngezinhlobo ezahlukene, kufaka phakathi amavalvu ebhola, amavalvu ebhabhathane, amavalvu esango, amavalvu embulunga, namavalvu e-SDV, okuvumela izimboni ukuthi zikhethe inketho efanele kakhulu ekusetshenzisweni kwazo okuthile. Ukuqonda izici ezihlukile nezinzuzo zohlobo ngalunye lwevalvu eqhutshwa umoya kubalulekile ekwenzeni ngcono ukusebenza nokuqinisekisa ukusebenza okuphephile kwezimboni. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, indima yamavalvu aqhutshwa umoya ekuthuthukiseni ukusebenza kahle kwenqubo kanye nokuthembeka izoba yinto ebaluleke kakhulu.
