I-plug valve iyi-valve ejikelezayo esesimweni selungu lokuvala noma i-plunger. Ngokujikeleza ama-degree angama-90, itheku lesiteshi kwi-plug ye-valve liyafana noma lihlukaniswe ethekwini lesiteshi emzimbeni we-valve, ukuze ukwazi ukubona ukuvulwa noma ukuvalwa kwe-valve.
Ukwakheka kwepulaki le-valve ye-plug kungaba cylindrical noma i-conical. Kuma-plugs we-cylindrical Valve, izindima zivame ukuthuthunda; Ema-plugs we-conical valve, izindima zihamba nge-trapezoidal. Lezi zimo zenza ukwakheka kokukhanya kwe-plug valve, kepha ngasikhathi sinye, kukhiqiza nokulahlekelwa okuthile. Ama-plug valves alungele kakhulu ukuvala imithombo yezindaba futhi exhuma imidiya kanye nokuphambukisa, kepha kuya ngohlobo lohlelo lokusebenza nokumelana nokuguguleka kwendawo yokubekwa uphawu, kungahle kusetshenziselwe ukuthuthumela. Guqula ipulaki ngokwewashi ukwenza i-groove pairallel ihambisane nepayipi ukuvula, bese ujikisa i-plag 90 degrees
Izinhlobo zama-plug valves ahlukaniswe ikakhulu ezigabeni ezilandelayo:
1. I-plug valve eqinisiwe
Ama-valves we-plug wohlobo oluqinile avame ukusetshenziswa kumapayipi aphansi aqonde ngqo. Ukusebenza kokubekwa uphawu kuxhomeke ngokuphelele ekulinganiseni phakathi kwepulaki kanye nomzimba we-plug. Ukucindezelwa kwendawo yokubekwa uphawu kutholakala ngokuqinisa i-nati ephansi. Ngokuvamile esetshenziselwa i-PN≤0.6MPA.
2. Ukupakisha i-plug valve
I-plug valve egcwele ukufeza ukufezekisa i-plug kanye nokufaka uphawu lomzimba ngokucindezela ukupakisha. Ngenxa yokupakisha, ukusebenza kokubekwa uphawu kungcono. Imvamisa lolu hlobo lwe-plug valve lune-gland epakisha, futhi ipulaki ayidingi ukuveza emzimbeni we-valve, ngaleyo ndlela kunciphisa indlela yokuvuza ye-medium esebenza. Lolu hlobo lwe-plug valve lusetshenziselwa kabanzi ngengcindezi ye-PN≤1MPA.
I-3.
I-valve ye-plug yokuzifaka ecashweni ibona uphawu lokucindezelwa phakathi kwepulaki kanye nomzimba we-plug ngokusebenzisa ingcindezi ye-medium uqobo. Ukuphela okuncane kwepulaki kuphuma phezulu emzimbeni, futhi okuphakathi kungena ukuphela okukhulu kwepulaki emgodini omncane endaweni yokungena, bese ipulaki licindezelwa phezulu. Lesi sakhiwo sivame ukusetshenziselwa abezindaba zomoya.
4. I-plug valve evaliwe kawoyela
Eminyakeni yamuva, uhla lwesicelo lwama-plug valves luye lwakhiwa ngokuqhubekayo, futhi ama-plug ama-plug avalwe kawoyela ngokuthambekele okuphoqelekile avele. Ngenxa yokuthambisa okuphoqelekile, kwakhiwa ifilimu lamafutha phakathi kobuso be-pairling we-plug kanye nomzimba we-plug. Ngale ndlela, ukusebenza kokubekwa uphawu kungcono, ukuvulwa nokuvala kuwukonga kwabasebenzi, futhi indawo yokubekwa uphawu ivinjelwe ukuba ilinyazwe. Kwezinye izikhathi, ngenxa yezinto ezahlukahlukene nezinguquko esigabeni sesiphambano, ukwanda okuhlukile kuzokwenzeka nakanjani, okuzokwenza ukonakala okuthile. Kumele kuqashelwe ukuthi lapho amasango amabili ekhululekile ukwandisa kanye nenkontileka, intwasahlobo kufanele futhi inwebe futhi inkeze nayo.
