I-valve yepulaki iyi-valve ejikelezayo esesimweni selungu elivalayo noma i-plunger. Ngokuzungezisa amadigri angu-90, imbobo yesiteshi kupulaki ye-valve iyafana noma ihlukaniswe nembobo yesiteshi emzimbeni wevalvu, ukuze kubonakale ukuvulwa noma ukuvala kwevalvu.
Ukuma kwepulaki ye-valve yepulaki ingaba yi-cylindrical noma i-conical. Kumapulaki angama-valve angama-cylindrical, amavesi ngokuvamile angama-rectangular; kuma-plugs e-valve e-conical, amavesi ane-trapezoidal. Lezi zimo zenza ukwakheka kwe-valve ye-plug ukukhanya, kodwa ngesikhathi esifanayo, kuphinde kukhiqize ukulahlekelwa okuthile. Ama-valve e-plug afaneleka kakhulu ukuvala nokuxhuma imidiya kanye nokuphambukisa, kodwa kuye ngohlobo lwesicelo kanye nokumelana nokuguguleka kwendawo yokuvala, angasetshenziswa futhi ekunyakaziseni. Vula ipulaki ngokwewashi ukuze wenze igroove ihambisane nepayipi ukuze ivuleke, futhi uvule ipulaki ngamadigri angu-90 ngokuphikisana newashi ukuze wenze umsele uqonde epayipini ukuze uvale.
Izinhlobo zama-valve amapulaki zihlukaniswa ngokuyinhloko ngezigaba ezilandelayo:
1. I-valve yepulaki eqinisiwe
Ama-valve amapulaki ohlobo oluqinile avame ukusetshenziswa kumapayipi aqonde adlule ngengcindezi ephansi. Ukusebenza kokuvala kuncike ngokuphelele ekulinganeni phakathi kwepulaki nomzimba wepulaki. Ukucindezelwa kwendawo yokubeka uphawu kufinyelelwa ngokuqinisa i-nati ephansi. Ngokuvamile isetshenziselwa i-PN≤0.6Mpa.
2. I-valve yepulaki yokupakisha
I-valve yepulaki epakishiwe ukuzuza ipulaki nokuxhuma ukuvala umzimba ngokucindezela ukupakisha. Ngenxa yokupakisha, ukusebenza kokubeka uphawu kungcono. Ngokuvamile lolu hlobo lwe-valve yepulaki lunendlala yokupakisha, futhi ipulaki ayidingi ukuphuma emzimbeni we-valve, ngaleyo ndlela inciphise indlela yokuvuza yendawo yokusebenza. Lolu hlobo lwe-valve yepulaki lusetshenziswa kabanzi ukucindezela kwe-PN≤1Mpa.
3. I-valve yepulaki ezivalayo
I-valve yepulaki ezivalayo ibona uphawu lokuminyanisa phakathi kwepulaki nomzimba wepulaki ngokucindezela kwe-medium ngokwayo. Isiphetho esincane sepulaki siphumela phezulu ngaphandle komzimba, kanti indawo emaphakathi ingena ekugcineni okukhulu kwepulaki ngembobo encane endaweni yokungena, futhi ipulaki icindezelwe phezulu. Lesi sakhiwo ngokuvamile sisetshenziselwa imidiya yomoya.
4. I-valve yepulaki evalwe ngamafutha
Eminyakeni yamuva nje, uhla lokusebenzisa ama-valve amapulaki luye lwandiswa ngokuqhubekayo, futhi kuye kwavela ama-valve epulaki avalwe ngowoyela anokugcoba ngempoqo. Ngenxa yokugcoba okuphoqelekile, ifilimu kawoyela yakheka phakathi kwendawo yokuvala yepulaki nomzimba wepulaki. Ngale ndlela, ukusebenza kokubekwa uphawu kungcono, ukuvula nokuvala kusindisa abasebenzi, futhi indawo yokuvala ivinjelwa ukuthi ingalimazi. Kwezinye izikhathi, ngenxa yezinto ezihlukene kanye nezinguquko ze-cross-section, ukwanda okuhlukile kuzokwenzeka nakanjani, okuzodala ukuguquguquka okuthile. Kumele kuqashelwe ukuthi lapho amasango amabili ekhululekile ukwandisa kanye nenkontileka, intwasahlobo kufanele futhi ikhule futhi inkontileka nayo.
