1 iimpawu zesakhiwo

1. I-Hemisphere

I-hemisphere ye-double-eccentricity half-ball valve yamkela uyilo oluphindwe kabini, inokutywinywa okuthembekileyo, ukukhululwa kwangoko, i-torque encinci, ubomi obude benkonzo, inokusetyenziswa kwimeko yokusebenza enzima yokuthutha i-granule medium. Umgaqo wesakhiwo kukuba umgca ophakathi we-hemisphere unobungakanani bokutshintsha kunye nomgca ophakathi we-stem kunye nomgca ophakathi wesihlalo. Xa ivulekile ngokupheleleyo, i-sphere kunye nesihlalo se-valve zahlukana ngokupheleleyo, kwaye kukho indawo ethile. I-radius yokujikeleza yahlulwe ibe yi-radius ende kunye ne-radius emfutshane. Kuya kubakho i-angle θ phakathi komgca we-tangent kwindlela ende yokujika ye-radius kunye nomphezulu wokutywina isihlalo. Xa i-valve ivula kwaye ivala, umphezulu wesihlalo esihlobene ne-hemisphere uya kuba nokwahluleka okuphuma kunye nokuza kwi-extrusion, ngaloo ndlela ukunciphisa ukungqoka komatshini kunye nokugqwala phakathi kwesihlalo kunye ne-hemisphere ngexesha lokusebenza, ukuphucula ubomi benkonzo.

2. Isihlalo valve

isihlalo senzelwe ukudiba, okunciphisa ubunzima bokuqhubekeka, ukuqinisekisa ukuhambelana phakathi komgca ophakathi wesihlalo se-valve kunye nendawo yokuqinisekisa ye-spherical ye-hemisphere, ngaloo ndlela ukuphucula ukusebenza kokuvala. Kukho indawo phakathi kwesihlalo nomzimba, ngoko xa ifakwe inokufumana ngokuzenzekelayo umgca ophakathi ngehemisphere ukufumana, ukuqinisekisa unxibelelwano olupheleleyo phakathi kwesihlalo ukutyanisa umphezulu kunye umphezulu spherical, oku kusombulula ukuvuza ngenxa machining ukuchaneka impazamo, ukuphucula ukusetyenziswa ibhola valve ukusebenza kunye nobomi bayo inkonzo

Ukutywinywa kwesihlalo nomzimba isakhiwo sokutywinywa okuqinileyo, esifanelekileyo kumaqondo obushushu aphezulu kunye neemeko zoxinzelelo oluphezulu. Isihlalo kunye nomphezulu wokunxibelelana wokutywina unexabiso elincinci le-c, kwaye umphezulu ngamnye wokutywina unemfuno ephezulu yokuchaneka. Xa ifakwe, isixhobo sokugcina sixhotyiswe sisitshixo sombane. Akusiyo nje kuphela isixhobo sokugcina esihlanganisiweyo nomzimba wevalve ukuthintela ukukhululeka, kodwa kwakhona isihlalo sokubha nokujikeleza. Iyahambelana nomgaqo wokudibanisa ukungcangcazela komatshini, okwenza isihlalo nomzimba bavalwe ngokuthembeka.

Yizinto ezimbini eziqinileyo phakathi kwesihlalo nomzimba okanye isihlalo kunye ne-hemisphere, ngoko ke le valve inokusetyenziswa kumaqondo obushushu aphezulu kunye neemeko zoxinzelelo oluphezulu.

3. Ezinye izinto zomatshini

Ivalve yonke yamkela uyilo lwemodyuli, isakhiwo esilula, ukuthembeka okulungileyo, ububanzi obuphezulu. I-valve stem yamkela isakhiwo se-jet. Iindlela zokuqhuba ezahlukeneyo. Ubungakanani bonxibelelwano be-valve stem, bracket kunye ne-actuators buhambelana nomgangatho we-ISO5211, inokudibaniswa ngqo kunye neenkcukacha ezahlukeneyo ze-actuators. Imodi yokuqhuba esetyenziswa ngokuqhelekileyo yi-manual, pneumatic, hydraulic kunye nombane, igesi kunye nokudibanisa ulwelo njl, ukuphucula ukusebenza kwe-double eccentric half-ball valve.

2 uluhlu lwezicelo

I-double-eccentricity half-ball valve ilungele zonke iintlobo zoshishino jikelele, eziphakathi ezifana namanzi, amanzi amdaka, amanzi amdaka, umphunga negesi njl. Ukuba isibini sokuvala sisebenzisa i-Cr-Mn-Si cemented carbide, kwaye sinemsebenzi wokukhusela umlilo kunye nokuqhuma kunye nokulwa ne-static, ngoko isebenza kwiimfuno zamaqondo obushushu aphezulu afana negesi, igesi yeoveni ye-coke, igesi yamanzi kunye negesi yendalo. Ukuba isibini sokuvala ((i-hemisphere, isihlalo se-valve) kunye nesijelo sokuhamba komzimba we-valve ngokusebenzisa i-tungsten carbide ekhethekileyo yokuqhubekeka kwezandla, iya kuba nezinzuzo ezifana nokusebenza kakuhle kunye nokonga amandla, ukumelana okulungileyo nokugqwala, ukusebenza okuthembekileyo kokuvala, ukusebenza okulula, ukuvula nokuvala ngokukhawuleza, ubomi obude benkonzo njl. Ngenxa yepropathi yokuhlukaniswa kwangoko kwe-hemisphere kunye nesihlalo kunye nokucinisekiswa kwangoko, isebenza kwimeko yokusebenza enzima yezinto eziphakathi eziqulathe iingxenye, inokusetyenziswa ngokubanzi kulawulo lwemibhobho eyahlukeneyo kumalahle aphuhliweyo, inkqubo yokuphuhlisa amalahle kunye nenkqubo yokuqokelela uthuli kwi-metallurgy, ukuqhubekeka kwemig Kwinkqubo yokukhutshwa kwangoko kunye nokucinisekiswa kwangoko, i-hemisphere kunye nesihlalo zicindezela kwaye zisike omnye, ezinokususa ukulinganisa kunye nokumanelela kumhlaba wokutywina, ukuqinisekisa ukutyiwa okuthembekileyo. Yikhetho elifanelekileyo kwiivalvu zezigaba ezimbini ezixutywe zefluid kwinkqubo yezobuchwepheshe yokuthutha ukulinganisa okulula ukuqhekeza, ukuqhekeza ukuqhekeza kwesisombululo se-pulp kunye ne-slurry ash.
