Ivalve yeplagi eLubricated yoShishino lwaseTshayina umniki-mveliso wemveliso
Yintoni ivalve yeplagi eLubricated?
Ivalve yeplagi ethambisayo iqulathe umngxuma kumbindi weplagi ecaleni kweaxis yayo.Lo mgodi uvalwe ezantsi kwaye ufakwe isitofu se-sealant-injection phezulu.I-sealant ifakwe kwi-cavity, kwaye ivalve yokutshekisha engaphantsi kwesitofu esifanelekileyo sithintela isitywina ukuba singagelezi 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,iivalve iplagi lubricatedziyilwa kwaye zisetyenziswa ngokubanzi.Ukongeza kwiimpawu ze-oyile yesiqhelo yeevalvu zeplagi, i-valve yeplagi elungelelanisiweyo 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 efakwe kwi-high-pressure ibangela ukuba umzimba weplagi uphakanyiselwe phezulu, ukuze umzimba weplagi kunye nomphezulu wokutywina wevalve ube. itywinwe ngcono.
- 2. Xa ivalve ivuliwe, uxinzelelo olukwigumbi elisezantsi lomzimba wevalve lulungelelaniswa noxinzelelo oluphakathi kumbhobho.Ioyile yokutywina yoxinzelelo oluphezulu kwigumbi eliphezulu ibangela ukuba umzimba weplagi utyhalelwe ezantsi, kwaye kubonakale umsantsa omncinci phakathi kwekhowuni yeplagi kunye nomgangatho wokutywina womzimba wevalve, itorque yomzimba weplagi ejikelezayo iyancitshiswa ngempumelelo.
Iimpawu eziphambili zevalve yeplagi eLubricated
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.

Ukusetyenziswa kwevalve yeplagi eLubricated
Ivalve yeplagi ethambisayoisetyenziswa kakhulu kumashishini ahlukeneyo afana nepetroleum, ishishini lemichiza, ikhemesti, isichumisi sekhemikhali, ishishini lamandla njalo njalo. Isetyenziswa phantsi koxinzelelo lwegama le-CLASS150-1500LBS, kwaye isebenza kubushushu be-40 ~ 450 ° C, Amanzi, iGesi, Umphunga kunye ne-oyile njl.
