Ibhalansi yokucindezela eguquliwe igcotshwe i-plug valve
Iyini i-Inverted pressure balance lubricated plug valve?
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,ama-plug valve agcotshwe ngebhalansi yokucindezela eguquliweasunguliwe 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.
- 3. Ezimweni zokushisa okuphezulu, ukwanda kokushisa kwepulaki kungamuncwa ukukhuphuka nokwehla kwayo. Ivalvu 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 ze-Inverted pressure balance lubricated plug valve
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.
- 4. Izinto zokwakha izingxenye nobukhulu be-flanges zingalungiswa ngokufanele ngokuya ngesimo sangempela sokusebenza sezidingo zamakhasimende, ukuze kuhlangatshezwane nezidingo ezahlukahlukene zobunjiniyela.
