I-Valve ye-Expension - isakhi esibalulekile ohlelweni lweqandi.
I-valve yokwanda iyingxenye ebalulekile yohlelo lokuqapha, okuvame ukufakwa phakathi kwesilinda sokugcina uketshezi kanye ne-evaporator. The expansion valve makes the liquid refrigerant of medium temperature and high pressure become low temperature and low pressure wet steam through its throttling, and then the refrigerant absorbs heat in the evaporator to achieve the refrigeration effect. I-valve yokwanda ilawulwa i-valve igeleza ngoshintsho olukhulu ngokuphela kokuphela kwe-evaporator ukuvikela ukusetshenziswa okunganele kwendawo ye-evaporator kanye ne-cylinder engqongqoza nto.
Isikhwama sokuzwakala sokushisa
Isiqandisi esikhokhiswa esikhwameni sokuzwakala kwezinga lokushisa sisesimweni sokulingana kwegesi-ketshezi, futhi le ngxenye yefriji ayidluliselwa esiqandisini ohlelweni. Kuvame ukuboshwa ipayipi lokuphuma kwe-evaporator, ukuxhumana okusondelene nepayipi ukuze kuzwakale i-evaporator ekhipha amazinga okushisa we-vapor, ngoba esiqandisini sawo sangaphakathi agcwele ukucindezelwa kwesifundazwe emzimbeni we-valve.
Ukulinganisa ishubhu
Elinye isiphetho seshubhu ebhalansi lixhumeke endaweni yokuphuma kwe-evaporator kancane kude nemvilovi yokushisa, futhi ixhunywe ngqo emzimbeni we-valve ngeshubhu le-capillary. Umsebenzi ukudlulisa ingcindezi yangempela yokuphuma kwe-evaporator emzimbeni we-valve. Kunama-diaphragms amabili emzimbeni we-valve, futhi i-diaphragm iqhubekela phezulu ngaphansi kwesenzo sengcindezi yokunciphisa ukugeleza okuqandayo nge-valve yokwanda futhi ufune ukulingana ku-valve.
Isahlulelo sekhwalithi
Isimo esisebenza kahle se-valve yokwanda kufanele kube ukushintsha ukuvulwa ngesikhathi sangempela futhi silawule izinga lokugeleza ngokushintsha komthwalo we-evaporator. Kodwa-ke, eqinisweni, ngenxa ye-hysteresis yezinga lokushisa elizwakala yimvilophu eshisayo ekudluliseni ukushisa, impendulo ye-valve yokwanda ihlala inesigamu se-hit slow. Uma sidweba umdwebo we-Flow Flow we-valve yokwanda, sizothola ukuthi akuyona ijika elibushelelezi, kodwa umugqa we-zigzag. Izinga le-valve yokwanda liboniswa ekuphumeni kosontekile futhi liphenduka, futhi likhudlwana inani eliphakeme, i-slower deach reaction kanye nekhwalithi embi kakhulu.
I-car air conditioner expansion valve yephukile
I-01 i-valve yokwanda ivulwa inkulu kakhulu
Ukuvula i-valve yokwanda kwezimo zomoya wezimoto ezinkulu kakhulu kungadala ukuthi umphumela wokupholisa wehle. Umsebenzi oyinhloko we-Valve Enweukwa ukuthi ulawule ukugeleza kwesiqandisi ku-Evaporator ukuze ulondoloze ingcindezi ephansi ku-Evaporator. Lapho i-valve yokwanda ivulwa kakhulu, ukugeleza okuqandayo kukhuphuka, okungenza ukuthi ingcindezi ephansi ku-evaporator ibe phezulu kakhulu. Lokhu kubangela ukuthi esiqandisini ukuba siguqulwe sibe ngoketshezi ngaphambi kwesikhathi ku-vaporator, okunciphisa umphumela wokufakwa kokushisa ku-evaporator. Ngakho-ke, umphumela opholile wesimo somoya wezimoto uzoncishiswa kakhulu.
Ukupholisa nokushisa akukuhle
Ukulimala kwe-valve yokwanda kwezimo zomoya wezimoto kuzoholela ekupholiseni okubi nokushisa umphumela. I-valve yokwanda idlala indima ekuqondiseni ukugeleza okuqandayo ohlelweni lomoya womoya. Lapho i-valve yokwanda ilimele, ukugeleza okuqandayo kungazinzile noma kukhulu kakhulu, ngaleyo ndlela kuthinta umphumela wokupholisa nokushisa. Ukusebenza okuthize yile: Kumodi eqandisi, izinga lokushisa ngaphakathi emotweni kungenzeka lingancishiselwe inani elibekiwe; In mode yokushisa, izinga lokushisa ngaphakathi emotweni kungenzeka lingavuki inani elibekiwe. Ngaphezu kwalokho, ukulimala kwe-valve yokwanda kungahle kuholele ekulimaleni kwezinye izingxenye zohlelo lokufaka umoya, kuthinta umphumela wokupholisa nokushisa. Ngakho-ke, uma umphumela wokupholisa noma wokushisa we-air conditioner utholakale ube mpofu, i-valve yokwanda kufanele ihlolwe ngesikhathi ukuze ibone ukuthi ilimele yini.
03 I-valve yokwanda incane kakhulu noma inephutha
Ukuvula i-valve yokwanda okuncane kakhulu noma ukungasebenzi kahle kungadala izinkinga ohlelweni lomoya wemoto. Lapho i-valve yokwanda ivulwa incane kakhulu, ukugeleza okuqandayo kuzokhawulelwa, okwenza umphumela wokupholisa wohlelo lokupholisa umoya wehle. Ngaphezu kwalokho, ngoba esiqandisini asigelizi ngokwanele emvelalweni, kungadala ukuthi i-evaporator ibe yiqhwa noma iqhwa ingaphezulu. Lapho i-valve ye-valve yehluleka ngokuphelele, uhlelo lokufaka umoya kungenzeka lungahleli noma lushise nhlobo. Kulokhu, udinga ukufaka esikhundleni i-valve yokwanda ngokushesha nje ukubuyisela isimo esijwayelekile sokusebenza sohlelo lokufaka umoya.
04 Ungaphumuli noma ulale emotweni ngesimo somoya isikhathi eside
Akukhona ukuhlakanipha ukuthi ungaphumuli noma ulale isikhathi eside emotweni nomoya ovulekile, ikakhulukazi uma kunenkinga nge-valve yokwanda kwezimo zomoya wemoto. Ama-valves wokunwetshwa yizakhi ezibalulekile ezinhlelweni zezimo ezimotweni ezisebenza ngezimoto futhi zinesibopho sokulawula ukugeleza nokucindezela okuqandayo. Lapho i-valve yokwanda ilimele, umphumela wokupholisa ungancishiswa noma wehluleke ngokuphelele. Emazingeni okushisa aphezulu, ukuvezwa isikhathi eside endaweni enjalo kungaholela ekuwohlokeni nasekukhathazekeni, ngisho nezimo ezisongela impilo. Ngakho-ke, uma uthola inkinga nge-valve yokwanda kwe-car air conditioner, kungcono ukugwema ukuphumula noma ukulala isikhathi eside emotweni ukuqinisekisa ukuphepha nenduduzo.
