I-valve yepulaki yesihlalo esithambile sezimboni esezingeni eliphezulu I-valve yepulaki egcotshwe ngotshani Umhlinzeki wefektri waseChina Umkhiqizi
Iyini ivalvu yepulaki yesihlalo esithambile?
Ivalvu yepulaki yesihlalo esithambile 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,Ivalvu yepulaki yesihlalo esithambileasunguliwe futhi asetshenziswa kabanzi. Ngaphezu kwezici zamavalvu epulaki ajwayelekile afakwe uwoyela, amavalvu epulaki alinganiselayo anezici ezilandelayo:
- 1. 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.
- 2. Ezimweni zokushisa okuphezulu, ukwanda kokushisa kwepulaki kungamuncwa ukukhuphuka nokwehla kwayo. I-valve yepulaki egcotshwe ngamafutha, yize ukusetshenziswa kokugcoba ngamafutha kunganciphisa ngokufanele i-torque yokuvula nokuvala, kodwa kungabangela ukungcola kwe-medium. Ngakho-ke, i-lubricant evaliwe ikhethwa ngokwezimo zokusebenza zangempela.
Izici eziyinhloko zevalvu yepulaki yesihlalo esithambile
Izici kanye nezinzuzo zeIvalvu yepulaki yesihlalo esithambile
- 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 kwevalvu yepulaki yesihlalo esithambile
Ivalvu yepulaki yesihlalo esithambileIsetshenziswa 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.
