I-valve yepulaki iyi-valve ejikelezayo esesimweni selungu lokuvala noma i-plunger. Ngokuzungeza ama-degree angu-90, i-port yesiteshi ku-plug yevalvu iyafana noma ihlukaniswe ne-port yesiteshi emzimbeni wevalvu, ukuze kubonakale ukuvulwa noma ukuvalwa kwevalvu.
Ukuma kwepulagi yevalvu yepulagi kungaba yi-cylindrical noma i-conical. Kuma-valve plugs e-cylindrical, ama-passage ngokuvamile ayi-rectangular; kuma-valve plugs e-conical, ama-passages ayi-trapezoidal. Lezi zinhlobo zenza isakhiwo se-valve yepulagi sibe lula, kodwa ngesikhathi esifanayo, futhi kudala ukulahlekelwa okuthile. Ama-plugs afaneleka kakhulu ekuvaleni nasekuxhumeni imidiya kanye nokuphambukisa, kodwa kuye ngohlobo lokusetshenziswa kanye nokumelana nokuguguleka kwendawo yokuvala, angasetshenziswa futhi ekugoqeni. Phendula ipulagi ngokwewashi ukuze wenze i-groove ifane nepayipi ukuze ivuleke, bese uphendula ipulagi ngama-degree angu-90 ngokuphambene newashi ukuze wenze i-groove iqonde ngqo epayipini ukuze ivale.
Izinhlobo zama-valve e-plug zihlukaniswe kakhulu ngezigaba ezilandelayo:
1. I-valve yepulagi eqinisiwe
Amavalvu epulaki aqinile avame ukusetshenziswa kumapayipi aqondile anomfutho ophansi. Ukusebenza kokuvala kuncike ngokuphelele ekulinganeni kwepulaki nomzimba wepulaki. Ukucindezelwa kwendawo yokuvala kufezwa ngokuqinisa i-nut engezansi. Ngokuvamile kusetshenziselwa i-PN≤0.6Mpa.
2. I-valve yepulagi yokupakisha
I-valve yepulaki epakishiwe ihloselwe ukufeza ukuvalwa komzimba wepulaki nepulaki ngokucindezela ukupakisha. Ngenxa yokupakisha, ukusebenza kokuvala kungcono. Ngokuvamile lolu hlobo lwe-valve yepulaki lune-gland yokupakisha, futhi ipulaki ayidingi ukuphuma emzimbeni we-valve, ngaleyo ndlela kunciphisa indlela yokuvuza yendawo yokusebenza. Lolu hlobo lwe-valve yepulaki lusetshenziswa kabanzi ekucindezelweni kwe-PN≤1Mpa.
3. I-valve yepulagi ezivala ngokwayo
I-valve yepulaki ezivala ngokwayo ibona uphawu lokucindezela phakathi kwepulaki nomzimba wepulaki ngokucindezela kwe-medium uqobo. Ingxenyana encane yepulaki iphuma phezulu emzimbeni, bese i-medium ingena engxenyeni enkulu yepulaki ngembobo encane ekungeneni, bese ipulaki icindezelwa phezulu. Lesi sakhiwo ngokuvamile sisetshenziselwa imidiya yomoya.
4. I-valve yepulaki evalwe ngowoyela
Eminyakeni yamuva nje, ububanzi bokusetshenziswa kwama-valve e-plug buye bandiswa njalo, futhi ama-valve e-plug avaliwe ngowoyela ane-lubrication ephoqelelwe avele. Ngenxa ye-lubrication ephoqelelwe, kwakheka ifilimu kawoyela phakathi kobuso bokuvala be-plug nomzimba we-plug. Ngale ndlela, ukusebenza kokuvala kungcono, ukuvulwa nokuvalwa konga abasebenzi, futhi ubuso bokuvala buvinjelwa ekulimaleni. Kwezinye izimo, ngenxa yezinto ezahlukene kanye nezinguquko esigabeni esiphambene, kuzokwanda okuhlukile ngokungenakugwenywa, okuzobangela ukuguquka okuthile. Kufanele kuqashelwe ukuthi lapho amasango amabili ekhululekile ukwandiswa nokuncipha, isiphethu kufanele sikhule futhi sinciphe naso.
