Loluphi uhlobo lwesiphakathi esinokudlula kuso ivalve yebhola?

Iivalvu zebhola zifanelekile kuluhlu olubanzi lwemidiya, kubandakanywa iimeko zokusebenza ngokubanzi kunye nezinzima, ngolu hlobo lulandelayo:

Indlela yokusebenza ngokubanzi:Iivalvu zebholazilungele imidiya eqhelekileyo njengamanzi, izinyibilikisi, iiasidi, kunye negesi yendalo. Inokwakheka okudibeneyo, ukutywinwa okuthembekileyo, kunye nomgangatho wokutywina uhlala kwindawo evaliweyo kunye ne-spherical surface, engenakunqanyulwa lula yi-medium kwaye kulula ukuyisebenzisa nokugcina. Ngokomzekelo, i-valve ye-valve ye-valve yensimbi engenasici yenziwe ngezinto zensimbi ezingenasici ezifana ne-304 kunye ne-316, kwaye izinto zokutywina zingakhethwa kwi-PTFE okanye i-metal hard seals, enokumelana neendaba ezahlukeneyo ezifana ne-acids, igesi yendalo, kunye neemveliso zeoli.

Iimeko zokusebenza ezimbi:Iivalvu zebholazikwalungele iimeko zokusebenza ezinemithombo yeendaba ezirhabaxa njengeoksijini, ihydrogen peroxide, i-methane, kunye ne-ethylene. Ezi midiya zinokuba neempawu ezifana nokubola, ukutsha, ukuqhuma, okanye ubushushu obuphezulu kunye noxinzelelo, kunye noyilo olukhethekileyo kunye nokukhethwa kwezinto eziphathekayo zeevalve zebhola kunokuhlangabezana nezi mfuno. Ngokomzekelo, iivalve zebhola ze-carbon steel zifanelekile kwimidiya kunye neqondo lokushisa elisebenzayo -100 ℃ ukuya kwi-600 ℃ kunye nomlinganiselo woxinzelelo lwe-1.0-64MPa, kwaye isetyenziswa ngokubanzi kwiikhemikhali, i-petroleum, amandla kunye nezinye iindawo.

Imidiya ekhethekileyo: Kumajelo akhethekileyo afana neefayili kunye neengqungquthela ezincinci eziqinileyo, iivalve zebhola nazo zinezisombululo ezihambelanayo. Umzekelo, kukho i-shear force eyomeleleyo phakathi kondoqo omilise u-V wevalve yebhola etywiniweyo enobume be-V kunye nesihlalo sevalve yesinyithi esidityaniswe nge-alloy eqinile, elungele kakhulu olu hlobo lwe-medium. Iivalvu zebhola ezininzi zinokulawula ngokuguquguqukayo ukudityaniswa, ukwahlula, kunye nokutshintsha indlela yokuhamba kwemidiya kwimibhobho, izenze zilungele iimeko ezifuna ulawulo oluntsonkothileyo lwemidiya.

Imithombo yeendaba ezonakalisayo: Kwimithombo yeendaba eyonakalisa kakhulu njenge-asidi yesulfuric, amanzi olwandle, njl.,iivalve zebholabanokuphucula ukuxhathisa kwe-corrosion ngokusebenzisa izinto ezifana ne-stainless steel 316L, i-Hastelloy, okanye i-lining kunye ne-PTFE, iingubo ze-ceramic, njl.
