Ivelufa yebhabhathane luhlobo lwevalvu esebenzisa uhlobo lwediski lokuvula nokuvala iindawo ukujikeleza malunga ne-90 ° ukuvula, ukuvala okanye ukulawula ukuhamba ngokuphakathi. Ivelufa yebhabhathane ayisiyonto ilula kuphela kulwakhiwo, ngobukhulu obuncinci, ubunzima bokukhanya, ukusetyenziswa kwezinto ezincinci, ubungakanani bokufakwa, encinci ekuqhubeni itorque, elula kwaye ekhawulezayo ekusebenzeni, kodwa ikwanomsebenzi wokulawula ukuhamba kakuhle kunye nokuvala iimpawu zokutywina kwangelo xesha. Ingenye yeentlobo zevalve ezikhawulezayo kule minyaka ilishumi idlulileyo. Iivali zebhabhathane zisetyenziswa kakhulu. Iindidi kunye nobungakanani bokusetyenziswa kwayo busanda, kwaye ikhula kwiqondo lobushushu eliphezulu, uxinzelelo oluphezulu, ubukhulu obukhulu, ukutywina okuphezulu, ubomi obude, iimpawu ezilawulayo ezigqwesileyo, kunye nemisebenzi emininzi yevalve enye. Ukuthembeka kwayo kunye nezinye izalathiso zomsebenzi ziye zafikelela kwinqanaba eliphezulu.
Ukusetyenziswa irabha zokwenziwa ukumelana irabha ivelufa ibhabhathane, ukusebenza ivelufa butterfly kungaphuculwa. Irabha Synthetic uneempawu nokumelana, ukumelana ukhukuliseko, uzinzo mbini, ukomelela elungileyo, lula ukuyila kunye neendleko eziphantsi, kwaye zingakhethwa ngokweemfuno ezahlukeneyo ukuhlangabezana neemeko zokusebenza ivelufa ibhabhathane.
I-Polytetrafluoroethylene (PTFE) inokumelana nokuqina komhlwa, ukusebenza okuzinzileyo, akukho lula ukuguga, ukungavumelani okuphantsi, ukwenza ngokulula, ubungakanani obuzinzileyo, kunye nokusebenza kwayo kungaphuculwa ngokuzalisa kunye nokongeza izinto ezifanelekileyo zokufumana izinto zokutywina zebhabhathane ngamandla angcono kunye ulungelelwaniso olusezantsi lokungqubana, oloyisa umda werabha yokwenziwa. Ke ngoko, i-polytetrafluoroethylene (i-PTFE) ngummeli wezinto zePolymer Polymer Composite kunye nokuzaliswa kwazo kugqityiwe kuye kwasetyenziswa kakhulu kwiivelufa zebhabhathane, ukuze ukusebenza kweebheyidi zebhabhathane kuphuculwe ngakumbi. Ivaluva zebhabhathane ezinobushushu obubanzi kunye noxinzelelo, ukusebenza ngokutywina okuthembekileyo kunye nobomi benkonzo obude buye kwaveliswa.
Ukuze kuhlangatyezwane neemfuno zobushushu obuphezulu kunye nobuphantsi, ukhukuliseko lomhlaba olomeleleyo, ubomi obude kunye nezinye izicelo zeshishini, isivingco sebhabhathane esitywiniweyo senziwe kakhulu. Ngokusetyenziswa kokumelana nobushushu obuphezulu, ukumelana nobushushu obuphantsi, ukomelela okunamandla, amandla okomelela okomeleleyo kunye nezinto eziphezulu zamandla e-alloy kwiiveluvane zebhabhathane, iivali zebhabhathane ezitywiniweyo ziye zasetyenziswa ngokubanzi kubushushu obuphezulu kunye nasezantsi, ukhukuliseko olomeleleyo, ubomi benkonzo ende kunye nokunye iinkalo zoshishino. Ivaluva zebhabhathane ezinobubanzi obukhulu (9 ~ 750mm), uxinzelelo oluphezulu (42.0mpa) kunye nobubanzi obubanzi beqondo lobushushu (- 196 ~ 606 ℃) zivele, ezenza itekhnoloji yebhola yamabhabhathane ifikelele kwinqanaba elitsha.
Isivalo sebhabhathane sinokumelana okuncinci kokuhamba xa kuvulwe ngokupheleleyo. Xa ukuvulwa kuphakathi kwe-15 ° ukuya kwi-70 ° kunokulawula ukuhamba ngokukhawuleza. Ke ngoko, ibhabhathane ivelufa isetyenziswa kakhulu kwicandelo lokulawula ubukhulu obukhulu.
Njengokuhamba kwentsimbi yevali yamabhabhathane ngokusula, uninzi lweevalvu zebhabhathane zinokusetyenziswa kunye neesuntswana ezixhonyiweyo eziphakathi. Ngokwamandla etywina, inokusetyenziselwa umgubo kunye nemithombo yeendaba granular.
Ivaluva zebhabhathane zilungele umgaqo wokuhamba. Kuba ilahleko yoxinzelelo lwevalveve yamabhabhathane kumbhobho mkhulu kakhulu, malunga namaxesha amathathu kwivalve yesango, ifuthe lokuphulukana noxinzelelo kwinkqubo yombhobho kufuneka liqwalaselwe ngokupheleleyo xa kukhethwa ivalve yamabhabhathane, kunye namandla epleyiti yebhabhathane ethwele umbhobho uxinzelelo oluphakathi xa kuvalwa kufuneka kuthathelwe ingqalelo. Ukongeza, umda wobushushu obusebenzayo bezinto zokuhlala ezihlaziyiweyo kubushushu obuphezulu kufuneka ziqwalaselwe.
Ubude besakhiwo nobude bevalve yamabhabhathane bincinci, isivinini sokuvula nokuvala sikhawulezile, kwaye sineempawu ezifanelekileyo zokulawula ulwelo. Umgaqo wesakhiwo weveluvane yebhabhathane yeyona ifanelekileyo yokwenza ivelufa enobubanzi obukhulu. Xa ivelufa yamabhabhathane kufuneka isetyenziselwe ukulawulwa kokuhamba, eyona nto ibaluleke kakhulu kukukhetha ngokuchanekileyo ubungakanani kunye nohlobo lwevalvu yebhabhathane, ukuze isebenze ngokufanelekileyo nangokufanelekileyo.
Ngokubanzi, ekurhashazeleni, kulawulo lokulawula kunye nodaka oluphakathi, ubude besakhiwo esifutshane, ukuvulwa ngokukhawuleza kunye nokuvalwa kwesantya kunye noxinzelelo oluncitshisiweyo (umahluko omncinci woxinzelelo) ziyafuneka, kwaye ivelufa yamabhabhathane iyacetyiswa. Ivelufa yebhabhathane ingasetyenziselwa ukuhlengahlengisa indawo kabini, ukunciphisa ishaneli, isandi esisezantsi, i-cavitation kunye ne-vaporization phenomenon, ukuvuza okuncinci emoyeni kunye nolwalamano oluphakathi. Uhlengahlengiso lokujija phantsi kweemeko ezikhethekileyo zokusebenza, okanye ukutywina okungqongqo, ukunxiba okunzima kunye nobushushu obuphantsi (cryogenic) iimeko zokusebenza ziyafuneka.
ulwakhiwo
Oku ikakhulu iqulunqwe umzimba wevalufa, intonga vana, ipleyiti ibhabhathane kunye ring uphawu. Umzimba wevalve uyilinda enobude obufutshane be-axial kunye neplani yamabhabhathane eyakhelweyo.
uphawu
1. Ivelufa yebhabhathane ineempawu zesakhiwo esilula, ivolumu encinci, ubunzima bokukhanya, ukusetyenziswa kwezinto eziphantsi, ubungakanani bokufakwa okuncinci, iswitshi ekhawulezayo, ukujikeleza okungama-90 °, itorque yokuqhuba encinci, njl.njl isetyenziselwa ukunqunyulwa, ukudibanisa nokulungelelanisa Phakathi kumbhobho, kwaye uneempawu ezifanelekileyo zokulawula ulwelo kunye nokusebenza ngokutywina.
2. Ivelufa yamabhabhathane ingahambisa udaka ize igcine nolwelo oluncinci emlonyeni wombhobho. Phantsi koxinzelelo oluphantsi, ukutywinwa okuhle kunokufezekiswa. Ukusebenza kakuhle kommiselo.
3. Uyilo lokulungelelanisa ipleyiti yamabhabhathane lwenza ukuba ilahleko yokunganyangeki kolwelo incinci, enokuthi ichazwe njengemveliso yokonga umbane.
4. Intonga yevalufa inokumelana kakuhle nomhlwa kunye nepropathi yokulwa lingonakali. Xa ivalvevvevve ivaliwe kwaye ivaliwe, intonga yevalve ijikeleza kuphela kwaye ayishukumi iye phezulu nasezantsi. Ukupakisha kwentonga yevalve akukho lula ukonakala kwaye ukutywina kunokwethenjelwa. Ilungiswe ngepini ye-taper yesitya sebhabhathane, kwaye isiphelo esandisiweyo siyilelwe ukukhusela intonga yevalve xa isiwa xa uqhagamshelo phakathi kwentonga yevalve kunye nembasa yamabhabhathane yophuka ngengozi.
5. Kukho uqhagamshelo esisangqa, uqhagamshelo uqinisa, uqhagamshelo lempundu ukuwelda kunye uqhagamshelo lug uqinisa.
Iifom zokuqhuba zibandakanya i-manual, i-worm gear drive, i-electric, i-pneumatic, i-hydraulic kunye ne-electro-hydraulic actuators, ezinokuthi zenze ulawulo lwerimowthi kunye nokusebenza okuzenzekelayo.
