Ibhalansi yoxinzelelo oluguquliweyo lubricated valve yePlag
Yintoni inverted pressure balance lubricated valve Plug ?
Ivalve yeplagi ethanjiswayo iqulathe umngxuma kumbindi weplagi ecaleni kweaxis yayo.Lo mgodi uvalwe ezantsi kwaye ufakwe isitofu se-sealant-injection phezulu.I-sealant ifakwe kwi-cavity, kwaye i-valve yokukhangela engaphantsi kwesitofu esifanelekileyo sithintela i-sealant ukuba ihambe kwicala elingasemva.Isitywina siphuma kumbindi womngxuma siphumela kwimingxuma emitha yemitha ukuya kwigrooves yezithambiso ezithi zinyukele kubude bomphezulu wokuhlala weplagi.
Ukuze kuncitshiswe i-torque yesitulo sentsimbi eqhelekileyo, iivalvu zeplagi ezithanjiswayo,inverted uxinzelelo ibhalansi lubricated plug valvesziyilwa kwaye zisetyenziswa ngokubanzi.Ukongeza kwiimpawu zeevalvu zeplagi ze-oyile eziqhelekileyo, i-valve yeplagi elinganayo yoxinzelelo nayo inezi mpawu zilandelayo:
- 1.Ikhowuni yeplagi yoxinzelelo olulungeleleneyo ivelufa yeplagi ifakwe kwindawo eguqulweyo.Kukho ivalve yokukhangela kwindawo ephezulu yekhowuni yeplagi.Xa ivalve ivaliwe, ngenxa yomahluko kwindawo ephezulu kunye nesezantsi yokusikwa kwekhowuni yeplagi, i-oyile yokutywinwa ephezulu yoxinzelelo ibangela ukuba umzimba weplagi uphakanyiselwe phezulu, ukuze umzimba weplagi kunye nomphezulu wokutywina unokuba itywinwe ngcono.
- 2. Xa ivalve ivuliwe, uxinzelelo olukwigumbi elisezantsi lomzimba wevalve lulungelelaniswa noxinzelelo oluphakathi kumbhobho.I-oyile yokutywina yoxinzelelo oluphezulu kwigumbi eliphezulu ibangela ukuba umzimba weplagi utyhalelwe ezantsi, kwaye kubonakale umsantsa omncinci phakathi kwekhowuni yeplagi kunye nomgangatho wokutywina womzimba wevalve, i-torque yomzimba weplagi ejikelezayo iyancitshiswa ngempumelelo.
- 3. Kwiimeko eziphezulu zokushisa, ukwandiswa kwe-thermal yeplagi kunokuthatyathwa ngokunyuka nokuwa kwayo.I-oil lubricated plug valve, nangona ukusetyenziswa kwe-oyile yokuthambisa kunokunciphisa ngokufanelekileyo i-torque yokuvula kunye nokuvala, kodwa inokwenza ungcoliseko oluphakathi.Ngoko ke, i-lubricant etywiniweyo ikhethwa kwiimeko zangempela zokusebenza.
Iimpawu eziphambili ze-Inverted pressure balance lubricated Plug valve
Iimpawu kunye neenzuzo zeIbhalansi yoxinzelelo oluguquliweyo lubricated valve yePlag
- I-1.Imveliso inesakhiwo esifanelekileyo, ukutywinwa okuthembekileyo, ukusebenza kakuhle kunye nokubonakala okuhle.
- I-2.Inokwakheka koxinzelelo lwe-flip-clip elinganiselayo kunye nokukhanya kokuvula / ukucima ukusebenza.
- 3.Umjelo we-oyile usetwe phakathi komzimba wevalvu kunye nomphezulu wokutywina, onokufaka igrisi yokutywina ukwandisa isakhono sokutywina.
- 4.Izixhobo zamalungu kunye nobukhulu beeflange zinokucwangciswa ngokufanelekileyo ngokweyona meko yokusebenza kweemfuno zabathengi, ukuze kuhlangatyezwane neemfuno ezahlukeneyo zobunjineli.
