Ivalve yokhuseleko lohlobo lwasentwasahlobo
| Uhlobo | Ivalve yoKhuseleko |
| Umzekelo | A68Y-P54110V, A68Y-P54140V, A68Y-P54200V, A68Y-P5432V, A68Y-P5445V, A68Y-P5464V |
| Idayamitha yeNominal | DN 40-150 |
Isebenza kumphunga, umoya kunye nezinye izixhobo eziphakathi okanye umbhobho (ubushushu bokusebenza ≤560℃ kunye noxinzelelo lokusebenza ≤20MPa) njengomkhuseli woxinzelelo olugqithisileyo.
- Ngoyilo lwesakhiwo sokukhutshwa okugcweleyo kwentwasahlobo, i-valve ine-coefficient enkulu yokukhupha, isakhiwo esilula, ukusebenza kakuhle kokutywinwa, uxinzelelo oluchanekileyo lokuvula, i-blowdown encinci, ukulungiswa kakuhle kunye nezinye iimpawu.
- Isihlalo sevalvu sisihlalo sevalvu yeLaval. Xa uqukuqela kwindawo yokuphuma yesitulo sevalve, umphunga ufikelela kwisantya esiphezulu kunye ne-coefficient yokukhupha enkulu, ekwaziyo ukunciphisa ubungakanani bofakelo lweevalvu zokhuseleko kwibhoyila. Ngokuqina kwe-alloy build-up welding, indawo yokutywina yesitulo sevalvu ibonakalisa ukuxhathisa kwe-abrasion, ukumelana nokhukuliseko kunye nobomi benkonzo ende.
- Ngokwakhiwa kwe-thermal elastic, i-disc yevalve isebenzisa i-deformation yayo encinci yembuyekezo phantsi kwamandla asebenzayo aphakathi ukuze kuphuculwe amandla okutywina kunye nokweyisa ukukhutshwa kwangaphambili kwevalve yokhuseleko xa uxinzelelo oluphakathi lusondela kuxinzelelo lokumisela. Ngetekhnoloji yokucima itekhnoloji ephezulu, indawo yokutywina yediskhi yevalvu iphucula ubulukhuni, i-abrasion resistant kunye ne-corrosion resistance.
- Impembelelo yeringi ephezulu yokulungelelanisa kukutshintsha indlela yokuhamba kwendawo ephakathi ukusuka kwisihlalo sevalve ukuguqula amandla aphikisayo aphakathi kwidiski yevalve. Ukuma kweringi yokulungelelanisa ephezulu kuchaphazela ukuvuthela kwevalve ngokuthe ngqo.
- Isithuba sonyaka senziwe phakathi komphezulu weringi yokulungelelanisa esezantsi kunye neplani esezantsi yediski yevalve. Uxinzelelo lutshintshwa ngokulawula umthamo wendawo yeringi esezantsi yokulungelelanisa ukufikelela kuxinzelelo olufanelekileyo lokuvula.
- Ukunyanzeliswa kwentwasahlobo kulungelelaniswa yi-nut elawulayo ukwenza ivalve ifumane uxinzelelo oluchanekileyo lokusetha ngokufanelekileyo kwaye ngokukhawuleza.
- I-backpressure adjusting sleeve yindlela encedisayo yokulungelelanisa i-valve disc backpressure. I-blowdown efanelekileyo inokufumaneka ngohlengahlengiso lwe-backpressure adjusting sleeve; lungelelanisa ukuya phezulu ukwehlisa umva kwaye ulungelelanise ukuya ezantsi ukonyusa umva kwevalvu.
- Isidibanisi sokupholisa sibekwe phakathi kwentwasahlobo kunye nomzimba wevalve ukukhusela intwasahlobo kwimpembelelo yobushushu obuphezulu kunye nokuqinisekisa ukuqina okuzinzileyo kunye nokuqhubekayo kwentwasahlobo.
- Intwasahlobo yinxalenye ebalulekileyo yokugqiba ukusebenza kwevalve yokhuseleko. Imithombo eyahlukeneyo yenzelwe ukusetwa koxinzelelo oluhlukeneyo kunye ne-blowdowns.
- I-isolator yokushisa ihlukanisa umzimba we-valve ukusuka entwasahlobo ukunciphisa impembelelo yobushushu entwasahlobo, ukuqinisekisa ukuqina kwentwasahlobo kunye nokwenza ukusebenza kwentwasahlobo kuzinzile.
