Okujwayelekile

Izici Zokuklama

1. uhlobo lomkhono wekhadi lokuvala ipulaki elithambile ukuvala ivalvu kwenziwa ngokuvala indawo ezungeze amasethi ekhadi, ukuvikela izindebe zensimbi okuyingqayizivele okungu-360 ° amasethi ekhadi angashintshi;
2. I-valve ayinakho umgodi wokuqongelela imidiya;
3. Udebe lwensimbi luhlinzeka ngomsebenzi wokuzihlanza ohlelweni lokuphotha, olufanele izimo ze-viscous nezilula kalula;
4. Ukugeleza kwezindlela ezimbili, kulula kakhulu ukusebenzisa ukufakwa;
5. Ubukhulu be-material kanye ne-flange yezingxenye zingakhethwa ngokuvumelana nezimo zangempela zokusebenza noma izidingo zabasebenzisi, futhi zihlangabezane nazo zonke izinhlobo zezidingo zobunjiniyela.
I-valve yepulaki yenkampani ye-Newsway Valve iyivalvu ejikelezayo enesiqephu esivalayo noma i-plunger.Ngokuzungezisa amadigri angu-90, imbobo yesiteshi kupulaki ye-valve ixhunywa noma ihlukaniswe nembobo yesiteshi emzimbeni wevalvu ukuze ibone ukuvulwa noma ukuvala.
Ipulaki ye-valve yayo ingaba yi-cylindrical noma i-conical.Kumapulaki angama-valve angama-cylindrical, iziteshi ngokuvamile ziwunxande;kuma-plug conical valve, iziteshi ziyi-trapezoidal.Lezi zimo zenza ukwakheka kwe-valve yepulaki kube lula.Ifaneleka kakhulu njengendlela yokusika kanye nokuxhumanisa kanye ne-shunt, kodwa kuye ngokuthi izakhiwo ezisebenzayo kanye nokumelana nokuguguleka kwendawo yokuvala, ngezinye izikhathi ingase isetshenziselwe ukudonsa.
Ama-valve epulaki ahlukaniswa ngokusetshenziswa kwawo: amapulaki athambile amapulaki amapulaki, ama-valve epulaki agcotshwe uwoyela, amapulaki okuphakamisa, amapulaki anezindlela ezintathu kanye namapulaki anezindlela ezine.
Amavalvu epulaki avaliwe ngokuvamile asetshenziswa ezindaweni ezinokhahlo ezifana nemithombo yezindaba ebolayo, enobuthi obukhulu kanye neyingozi enkulu, lapho ukuvuza kunqatshelwe khona ngokuqinile, nalapho okubalulekile kwamavalvu kungangcolisi imidiya.Umzimba we-valve ungakhethwa ku-carbon steel, i-alloy steel kanye nensimbi engagqwali ngokusho kwendawo yokusebenza.
Amavalvu epulaki aqinile agcotshisiwe angahlukaniswa abe amapulaki agcotshisiwe ajwayelekile kawoyela kanye namavalvu epulaki alinganiselayo ngomfutho.Amafutha akhethekile ajovwa kusukela phezulu emzimbeni wepulaki phakathi kwembobo yekhoni yomzimba we-valve kanye nomzimba wepulaki ukuze kwakheke ifilimu kawoyela ukuze kuncishiswe itorque yokuvula nokuvala yevalvu futhi kuthuthukiswe ukusebenza kokuvala nempilo yesevisi.Ingcindezi yokusebenza ingafinyelela ku-64MPa, izinga lokushisa eliphakeme lokusebenza lingafinyelela kumadigri angama-325, futhi ububanzi obukhulu bungafinyelela ku-600mm.
Ama-valve epulaki aphakamisayo anamafomu ahlukahlukene esakhiwo.Lapho i-valve ivuliwe, ipulaki iyaphakanyiswa, futhi ipulaki ijikeleziswa ngamadigri angu-90 ekuvuleni okugcwele kwe-valve ukuze kuncishiswe ukungqubuzana nendawo yokuvala yomzimba we-valve;lapho i-valve ivaliwe, ipulaki ijikeleziswa ngamadigri angu-90 endaweni evaliwe.Yehlisa ukuze uthinte indawo yokuvala ye-valve ukuze ufinyelele ukuvala.
Ama-stopcock anezindlela ezintathu kanye nezine afanele ukushintsha indlela yokugeleza okuphakathi noma ukusatshalaliswa okuphakathi.Ngokwezidingo zezimo zokusebenza, ungakhetha i-soft seal bushing noma ukubekwa uphawu okuthambile, i-valve yokuphakamisa uphawu oluqinile.
