Nakuziwa ephasini lamavalvu we-butterfly wokuthengisa, akusizo zoke iinsetjenziswa ezenziwe ngokulinganako. Kunomehluko omnengi hlangana neenkambo zokukhiqiza kanye namadivayisi ngokwawo atjhugulula iimfanelo namakghono khulu. Ukuzilungiselela kuhle ukwenza ukukhetha, umthengi kufanele afunde ithekhnoloji nomehluko emhlobeni ngayinye ukukhetha idivayisi yakhe kuhle.
1.Ukwakhiwa kwamavalvu we-Butterfly
Iinsetjenziswa zokwakha ivalvu ziqunta amandla wayo nokuphila kwayo isikhathi eside. Amavalvu aklanyelwe ukugeleza okukhulu, ukugandeleleka okukhulu, nokusetjenziswa kwesikhathi eside, khulukhulu eendaweni ezikude, avamise ukwakhiwa ngensimbi ephosiweko nofana eqinisiweko. Ezinye iinhlobo ezenzelwe ukusetjenziswa okulula nofana ukusetjenziswa isikhathi esifitjhani zenziwa ngezinto ezifana ne-alloy elula, i-aluminium, nofana iplastiki ye-PVC. Amavalvu wekhwalithi ephezulu enzelwe ukujamelana nobudisi bokuphatha umfutho omkhulu khulu, athwale ukugeleza okukhulu kwezinto, begodu abe nokuqina okutlhogekako ukusetjenziswa isikhathi eside. Emadivayisini aseendaweni ezibudisi ukufikelela kizo nofana angcwatjhwe ngaphasi kwehlabathi, kutlhogeka ivalvu yesitayela esingapheliko. Iindleko zokufikelela idivayisi enjalo ukuze ifakwe esikhundleni sayo zivamise ukuba ziphezulu, njeke ukutjala imali ku-valve yekhwalithi ephezulu ukusuka ekuthomeni kukhetho oluhlakaniphileko.
2.Iinsetjenziswa ezithileko
Ukukhetha ivalvu ngokuya ngokusetjenziswa okuthileko kuqakathekile. Ezinye zilula begodu zenzelwe ukulawula amalayini wamanzi amancani nofana ukulawula amalayini wephethiloli. Ama-aquarium, amadamu, kanye neenhlelo zokufafaza ziimbonelo ezihle zokusetjenziswa okulula, okungakaqakatheki kwamavalvu we-butterfly.
Iinsetjenziswa ezitlhoga khulu ezifana namaphayiphi wegesi, amahlelo wokuthutha amafutha nofana amahlelo wokutjhugulula amanzi wedorobha anegandelelo eliphezulu atlhoga amavalvu wekhwalithi ephezulu, athembekileko anesikhathi eside sokuphila. Amadivayisi la asebenza budisi ahlolwa efemini malungana nokusebenza nokuthembeka, ukuhlangabezana nokudlula iimfuno zemisebenzi eqakathekileko.
Iinqophiso zomkhiqizi zingaveza imininingwana yama-nuts-and-bolts wamakghono wevalvu ngayinye. Ukukhetha ivalvu efaneleko yomsebenzi kuqakathekile ekusetjenzisweni kwesikhathi eside ngokunciphisa amathuba wokuhluleka kwemitjhini.
3.Izinga lokunemba
Enye into eqakathekileko ekukhetheni ivalvu yokusetjenziswa yizinga lokunemba elenziwe ngaphakathi kwedivayisi. Ivalvu ngayinye ineenhlathululo eziveza inani lokuvuza, nangabe likhona, endaweni yokuvala, ukuthi umzila ubanzi kangangani, ivolumu yamanzi engadlula lokha nayivulwe ngokupheleleko, nokuthi ivalvu ithembeke kangangani isikhathi eside. Ama-specs abuye abe nemininingwana yebelo lokusebenza kwevalvu, elungele izehlakalo lapho ukusebenza ngesikhathi kutlhogeka khona.
4.Iinkhetho zokulawula
Into eqakathekileko elandelako ekukhetheni ivalvu yomsebenzi othileko yindlela yokulawula. Amanye amavalvu afaka hlangana i-lever nofana isibambo, esenzelwe ukutjhugululwa ngesandla ukusuka ekuvuleni ukuya ekuvalekeni. Isibambo sivamise ukuba nekota yokujika ukusuka ekugcineni ukuya ekugcineni, ukutjhugulula msinyana nangokulula ubujamo bevalvu. Ezinye zenzelwe bona zenzeke ngokuzenzakalelako ngokusebenzisa isisetjenziswa sokutjhugulula esifana ne-solenoid nofana enye indlela yokukhamba.
Amavalvu athuthukileko afakahlangana irherho lokulawula elisebenza ngegezi elizeleko. Imoto le ingajikelezisa ngqo ishafu yevalvu nofana ithuthe iliva ngokusebenzisa ingalo ye-actuator. Nanyana kunjalo inikela ngokulawula okupheleleko ukusuka endaweni ekude begodu ingasetjenziselwa ukulungisa ukulawula ukugeleza okuqondileko nangabe kuyatlhogeka.
5.Umthamo wevalvu
Into yokugcina ekukhetheni ivalvu mthamo wedivayisi. Lokhu kufaka hlangana ukugeleza okuthileko kokuthi kungakanani izinto ezidluliswa nge-valve ngesikhathi esithileko, nokuthi kungakanani ukugandeleleka kwangaphakathi i-valve engakghona ukubekezelela ngokuphepha. Eensetjenzisweni ezinomfutho omkhulu, ezigeleza khulu zitlhogeka ivalvu ekulu, esezingeni eliphezulu, enesayizi efaneleko ukufanisa ihlelo lamapayipi anamathiselweko. Qiniseka bona uhlola iimfanelo ngokujamelana neendingo zakho ezithileko ukuqinisekisa bona ivalvu inamandla aneleko wokusetjenziswa.
