I-valve yepulaki egcotshwe ngezimboni Umkhiqizi wasefektri waseChina
Iyini i-valve yepulaki egcotshwe ngotshani?
I-valve yepulaki egcotshwe ngotshani inembobo ephakathi kwepulaki eceleni kwe-axis yayo. Lembobo ivaliwe phansi futhi ifakwe i-sealant-injection fitting phezulu. I-sealant ifakwa emgodini, futhi i-check valve ngaphansi kwe-injection fitting ivimbela i-sealant ukuthi igeleze ngendlela ephambene. I-sealant iphuma emgodini ophakathi ngemigodi ye-radial iye emiseleni yokugcoba edlula ubude bendawo yokuhlala yepulaki.
Ukuze kuncishiswe i-torque yamavalvu epulaki agcotshwe ngesihlalo sensimbi esivamile,amavalvu epulaki agcotshwe ngokhilimuasunguliwe futhi asetshenziswa kabanzi. Ngaphezu kwezici zamavalvu epulaki ajwayelekile afakwe uwoyela, amavalvu epulaki alinganiselayo anezici ezilandelayo:
- 1. Ikhoni yepulaki yevalvu yepulaki egcotshwe ngokulinganisela kokucindezela ifakwe endaweni eguquliwe. Kukhona ivalvu yokuhlola engxenyeni engenhla yekhoni yepulaki. Lapho ivalvu ivaliwe, ngenxa yomehluko endaweni engenhla nengezansi yokusika yekhoni yepulaki, uwoyela wokuvala ocindezelwe kakhulu ojoviwe ubangela ukuthi umzimba wepulaki uphakanyiswe phezulu, ukuze umzimba wepulaki kanye nobuso bokuvala ivalvu kungavalwa kangcono.
- 2. Uma ivalvu ivuliwe, ingcindezi ekamelweni elingezansi lomzimba wevalvu ilinganiswa nengcindezi ephakathi epayipini. Uwoyela wokuvala ocindezela kakhulu ekamelweni eliphezulu ubangela ukuthi umzimba weplagi ucindezelwe phansi, bese kuvela igebe elincane phakathi kwekhoni yeplagi kanye nobuso bokuvala bomzimba wevalvu, i-torque yomzimba weplagi ojikelezayo incishiswa ngempumelelo.
Izici eziyinhloko ze-valve yepulaki egcotshwe ngotshani
Izici kanye nezinzuzo zeIbhalansi yokucindezela eguquliwe igcotshwe i-plug valve
- 1. Umkhiqizo unesakhiwo esinengqondo, ukuvalwa okuthembekile, ukusebenza okuhle kakhulu nokubukeka okuhle.
- 2. Inesakhiwo sokucindezela okulinganiselayo kwe-flip-clip kanye nokusebenza kokukhanya kokuvula/ukuvala.
- 3. Kubekwa umsele wamafutha phakathi komzimba we-valve kanye nobuso besivalo, okungase kufake amafutha esivalo ukuze kwandiswe amandla esivalo.

Ukusetshenziswa kwe-valve yepulaki egcotshwe ngotshani
I-valve yepulaki egcotshwe ngotshaniIsetshenziswa kabanzi ezimbonini ezahlukahlukene ezifana nephethiloli, imboni yamakhemikhali, ikhemisi, umanyolo wamakhemikhali, imboni yamandla njll. Isetshenziswa ngaphansi kwengcindezi encane ye-CLASS150-1500LBS, futhi isebenza ekushiseni okungu--40~450° C, Amanzi, Igesi, Umusi kanye namafutha njll.
