Ivalve yebhabhathane ene-eccentric ephindwe kabini ithiywe ngezakhiwo zayo ezimbini.Ke injani i-double eccentric structure injani?
Into ebizwa ngokuba yi-double eccentric, eyokuqala i-eccentric ibhekisa kwishafti yevalve ephuma embindini womphezulu wokutywina, okuthetha ukuba isikhondo sisemva kobuso bepleyiti yevalve.Obu buchwephesha benza umphezulu woqhagamshelwano wepleyiti yevalve kunye nesihlalo sevalvu ube yindawo yokutywina, ethi iphumelele ngokusisiseko iziphene ezikhoyo kwiivalvu zebhabhathane ezixineneyo, ngaloo ndlela kususa ukuvuza okunokwenzeka kwangaphakathi kwindawo ephezulu nasezantsi yokudibana phakathi kweshafti yevalve kunye. isihlalo sevalve.
Enye i-eccentricity ibhekiselele kwiziko lomzimba wevalve kunye ne-axis ye-stem ekhohlo nasekunene, oko kukuthi, isiqu sahlula ipleyiti yebhabhathane ibe ngamacandelo amabini, enye ngaphezulu kwaye enye ngaphantsi.Le eccentricity inokwenza ipleyiti yebhabhathane ekuvuleni nasekuvaleni inkqubo inokukhutshwa ngokukhawuleza okanye isondele kwisihlalo sevalve, inciphise ukungquzulana phakathi kwepleyiti yevalve kunye nesihlalo sevalve etywiniweyo, ukunciphisa ukukrala nokukrazula, ukunciphisa ukuvuleka nokuvala itorque, kwaye ukwandisa ubomi benkonzo yesitulo sevalvu.
Zitywinwa njani iivalufa zebhabhathane eEccentric ephindwe kabini?
Isangqa sangaphandle sepleyiti yevalvu kunye nesihlalo esitywiniweyo sevalve yebhabhathane ephindwe kabini zenziwa ngoomatshini kumphezulu we-hemispherical, kwaye umphezulu ongaphandle ongqukuva wepleyiti yevalvu ucinezela umphezulu ongaphakathi ongqukuva wesihlalo esitywiniweyo ukuvelisa ukonakala okulastiki ukuphumeza ukuvala okuvaliweyo. urhulumente.Itywina levalve yebhabhathane eneeccentric ephindwe kabini lelendawo yokutywina, nto leyo ethetha ukuba indawo yokutywina yepleyiti yevalvu kunye nesitulo sevalvu sinxibelelene nomgca, kwaye umsesane wokutywina wenziwa ngerabha okanye i-PTFE.Ngoko ke ayichasananga noxinzelelo oluphezulu, kwaye isicelo kwinkqubo yoxinzelelo oluphezulu luya kukhokelela ekuvuzeni.
Leliphi Elona Candelo liPhambili leValve yeBhava nge-Eccentric?
Ukusuka kulo mfanekiso ungasentla, sinokubona ngokucacileyo ukuba awona macandelo aphambili e-Double Eccentric Butterfly Valve aqulathe ezi zinto zisixhenxe zilandelayo:
Umzimba: Izindlu eziphambili zevalve, ngokuqhelekileyo zenziwe ngentsimbi, i-ductile iron, okanye insimbi engenasici, yenzelwe ukubeka izinto zangaphakathi zevalve.
I-Disc: Inxalenye esembindini yevalvu ejikeleza ngaphakathi kumzimba wevalvu ukulawula ukuhamba kolwelo.I-disc idla ngokwenziwa ngentsimbi etyhidiweyo, intsimbi etyhidiweyo okanye ubhedu kwaye inemilo ecaba okanye egobileyo ehambelana nokumila kwevalve yomzimba.
I-Shaft Bearings: iibheringi ze-shaft zibekwe kumzimba we-valve kwaye zixhasa i-shaft, zivumela ukuba zijikeleze kakuhle kwaye zinciphise ukungqubuzana.
Umsesane wokutywina: umsesane wokutywina werabha umiliselwe kwipleyiti yevalve ngepleyiti yoxinzelelo kunye nezikrufu zentsimbi engenasici, kwaye umlinganiselo wokutywina wevalve uhlengahlengiswa ngokuhlengahlengisa izikrufu.
Isihlalo sokutywina: yinxalenye yevalvu evala idiski kwaye inqande ukuvuza kwamanzi ngevalve xa ivaliwe.
Ishafu yokuqhuba: idibanisa i-actuator kwi-flap yevalve kwaye ihambisa amandla ahambisa i-valve flap kwindawo oyifunayo.
I-Actuator: ilawula indawo yediski ngaphakathi kumzimba wevalvu.Kwaye ngokuqhelekileyo inyuswe phezu komzimba wevalvu.
Umthombo womfanekiso: Hawle

Izinto eziluncedo kunye nezingeloncedo kwiValve yeButterfly ephindwe kabini
Izinto eziluncedo:
1 Uyilo olunengqiqo, ulwakhiwo oludibeneyo, kulula ukuyifaka kunye nokuqhaqha, ukusebenza okuguquguqukayo, ukugcinwa kwabasebenzi, ukulungeleka, kunye nokugcinwa lula.
I-2 Isakhiwo se-eccentric sinciphisa ukungqubuzana kwendandatho yokutywinwa kunye nokwandisa ubomi benkonzo yevalve.
3 Itywinwe ngokupheleleyo, ukuvuza kwe-zero.Ingasetyenziswa kwimeko yevacuum ephezulu
4 Guqula imathiriyeli yesitywina sepleyiti yevalve, ipleyiti yebhabhathane, shaft, njl.
5 Isakhiwo sesakhelo, amandla aphezulu, indawo enkulu yokuphuphuma, ukuchasana kokuhamba okuncinci
Izinto ezingeloncedo:
Ngenxa yokuba ukutywina kusisakhiwo sokutywina, indawo yokutywina yepleyiti yebhabhathane kunye nesihlalo sevalve zinxibelelene nomgca, kwaye ukutywina kuveliswa yi-deformation elastiki ebangelwa yipleyiti yebhabhathane ecinezela isihlalo sevalve, ngoko ifuna ukuvala okuphezulu. isikhundla kwaye unomthamo ophantsi woxinzelelo oluphezulu kunye nobushushu obuphezulu.
