1. Uxinzelelo lwegama (PN)
Uxinzelelo lwegama lweivelufa butterflylixabiso lesalathiso elinxulumene namandla okumelana noxinzelelo lwamacandelo enkqubo yombhobho.Ibhekisa kuyilo olunikiweyo loxinzelelo olunxulumene namandla omatshini amacandelo ombhobho.
Uxinzelelo lwegama levalve yebhabhathane ngamandla okumelana noxinzelelo lwemveliso (ezi zilandelayo zizivalo) kwiqondo lobushushu elisezantsi.Izinto ezahlukeneyo zinobushushu obusezantsi obuhlukeneyo kunye namandla oxinzelelo.
Uxinzelelo lwegama, olumelwe sisimboli PN (MPa).I-PN luphawu lwendibaniselwano yoonobumba kunye namanani asetyenziselwa ireferensi enxulumene neempawu zoomatshini kunye neempawu ezinobungakanani bamacandelo enkqubo yemibhobho.
Ukuba uxinzelelo lwegama yi-1.0MPa, yirekhode njenge-PN10.Kwintsimbi etyhidiweyo kunye nobhedu ubushushu bereferensi yi-120 ° C: kwintsimbi yi-200 ° C kunye nentsimbi ye-alloy yi-250 ° C.
2. Uxinzelelo lomsebenzi (Pt)
Uxinzelelo lokusebenza lweivelufa butterflyibhekisa kuxinzelelo oluphezulu oluxeliweyo ngokusekelwe kubushushu bokugqibela bokusebenza kwinqanaba ngalinye lendawo yothutho yombhobho ukuze kusebenze ngokukhuselekileyo inkqubo yombhobho.Ukuthetha nje, uxinzelelo lokusebenza lolona xinzelelo luphezulu olunokuthi lunyamezele inkqubo ngexesha lokusebenza okuqhelekileyo.
3. Uxinzelelo loyilo (Pe)
Uxinzelelo loyilo lwevalve yebhabhathane lubhekiselele kuxinzelelo oluphezulu olukhawulezileyo olukhutshwa yinkqubo yoxinzelelo lwemibhobho kudonga lwangaphakathi lwevalvu.Uxinzelelo loyilo kunye neqondo lokushisa elihambelanayo loyilo lisetyenziswa njengemeko yomthwalo woyilo, kwaye ixabiso layo aliyi kuba ngaphantsi koxinzelelo lokusebenza.Ngokuqhelekileyo, olona xinzelelo luphezulu inkqubo inokuthwala lukhethwa ngexesha lokubala loyilo njengoxinzelelo loyilo.
4. Uxinzelelo lovavanyo (PS)
Kwiivalvu ezifakelweyo, Uxinzelelo lovavanyo lwevalve yebhabhathane lubhekisa kuxinzelelo ekufuneka ivalvu ifikelele xa isenza uvavanyo lwamandla oxinzelelo kunye nokuqina komoya.
5. Ubudlelwane phakathi kwezi ngcaciso zine
Uxinzelelo lwegama lubhekiselele kumandla oxinzelelo kwiqondo lokushisa elisezantsi, kodwa kwiimeko ezininzi, alisebenzi kwiqondo lokushisa elisezantsi.Njengoko ubushushu butshintsha, amandla oxinzelelo lwevalve nawo ayatshintsha.
Kwimveliso enoxinzelelo oluthile lwegama, uxinzelelo olusebenzayo olunokumelana nalo luchongwa ngukushisa okusebenzayo kwendawo.
Uxinzelelo oluqhelekileyo kunye noxinzelelo lokusebenza oluvumelekileyo lwemveliso efanayo luya kuhluka kumaqondo okushisa ahlukeneyo.Ukusuka kumbono wokhuseleko, uxinzelelo lovavanyo kufuneka lube lukhulu kunoxinzelelo oluncinci.
Kwinjineli, uxinzelelo lovavanyo> uxinzelelo lwegama> uxinzelelo loyilo> uxinzelelo lokusebenza.
Ngamnyeivelufa kuqukaivelufa butterfly, i-valve yesango kunye ne-valve yokukhangela kwi-valve ye-ZFA kufuneka ihlolwe uxinzelelo ngaphambi kokuthunyelwa, kwaye uxinzelelo lokuvavanya lukhulu okanye lulingana nomgangatho wokuvavanya.Ngokuqhelekileyo, uxinzelelo lovavanyo lomzimba we-valve ngama-1.5 amaxesha oxinzelelo lwe-nominal, kwaye isitywina si-1.1 amaxesha oxinzelelo lwegama (ixesha lovavanyo alikho ngaphantsi kwemizuzu emi-5).
