Indlela yokulawula ngokuchanekileyo izinga lokuhamba kweevalve zebhabhathane?

Ulawulo oluchanekileyo lweivelufa butterflyukuhamba kufuna ingqwalasela ebanzi yezinto ezininzi kunye nemilinganiselo ekujoliswe kuyo. Okokuqala, ukukhetha iivalve zebhabhathane kubalulekile. Iimpawu ezifanelekileyo kunye neentlobo zeevalve zebhabhathane kufuneka zikhethwe ngokusekelwe kuluhlu lokuhamba, iimfuno zoxinzelelo, kunye neempawu eziphakathi kweemeko zokusebenza zangempela. Ngokomzekelo, kwiimeko apho kufuneka ummiselo ophezulu wokuchaneka kwaye i-medium yi-fluid ecocekileyo, i-valve ye-butterfly etywiniweyo ethambileyo ingasetyenziswa, enomsebenzi wokutywinwa kakuhle kwaye inokunciphisa impembelelo yokuvuza kwangaphakathi kulawulo lokuhamba; Ukuba i-medium iqulethe ukungcola, i-hard sealedivelufa butterflyifaneleke ngakumbi ukuphepha umphezulu wokutywina ukuba unganxitywa kwaye uchaphazele ukuchaneka kohlengahlengiso.

Okwesibini, ukhetho kunye nokulungiswa kwe-activator ngamanyathelo aphambili. I-actuator yombane ineempawu zesantya sokuphendula ngokukhawuleza kunye nokuchaneka kokulungiswa okuphezulu. Ngokumisela ngokuchanekileyo iiparamitha zabo zokulawula, ezifana nokuchaneka komqondiso wokulawula ukuvulwa kunye nexesha lokuphendula le-activator, ulawulo oluchanekileyo lokuvula i-butterfly valve lunokufezekiswa, ngaloo ndlela lulungelelanisa ngokuchanekileyo izinga lokuhamba; Ii-actuator ze-pneumatic kufuneka ziqinisekise ukubonelela ngokuzinzile kwegesi kunye nokulawulwa ngokuchanekileyo koxinzelelo. Ngokulungelelanisa i-valve yokulawula i-pneumatic ukuguqula uxinzelelo lomoya olungena kwi-actuator, ukuvulwa kwe-valve ye-butterfly kunokulawulwa ngokuchanekileyo ukufezekisa ulawulo oluchanekileyo lokuhamba.

Ngaphaya koko, inkqubo yokuhlohla ayinakungahoywa. Izivalo zebhabhathane kufuneka zifakwe kwimibhobho ethe tyaba, kwaye ishafti yevalve kufuneka igcinwe kwindawo ethe tye ukuthintela utshintsho kwimeko yokuqukuqela kwamanzi okubangelwa kukuthambeka kokufakela, okunokuchaphazela ukuchaneka kommiselo wokuhamba; Ngexesha elifanayo, kuyimfuneko ukuqinisekisa ukuba ubude bamacandelo ombhobho othe tye ngaphambi nangemvaivelufa butterflyiyahlangabezana neemfuno. Ngokuqhelekileyo, ubude becandelo lombhobho othe tye alikho ngaphantsi kwamaxesha ali-10 ububanzi bombhobho, kwaye ubude becandelo lombhobho othe tye ngasemva alikho ngaphantsi kwamaxesha ama-5 ububanzi bombhobho, ukuze ulwelo lukwazi ukwenza imo yokuqukuqela ezinzileyo ngaphambi kokungena kwivalve yebhabhathane, ukunciphisa uphazamiseko lwemisinga eddy kunye nesiphithiphithi kumlinganiselo wokuqukuqela, kunye nokubonelela ngedatha echanekileyo esisiseko yolawulo oluchanekileyo.

Ukongeza, kweyona nkqubo yokusebenza, kuyafuneka ukuba kusetyenziswe izixhobo zokulinganisa ukuqukuqela okunje ngeemitha zokuqukuqela ze-iturbine, iimitha zokuqukuqela kombane, njl. njl. ukujonga ukuhamba ngexesha lokwenyani. Iimpawu zokuhamba ezilinganisiweyo zibuyiselwa kwinkqubo yokulawula, kwaye inkqubo yokulawula ngokuzenzekelayo ilungelelanisa ukuvulwa kwevalve yebhabhathane ngokusekelwe ekuphambukeni phakathi kwexabiso lokuhamba okumiselweyo kunye nexabiso lokulinganisa langempela, ukwenza ulawulo oluvaliweyo kunye nokuphumeza ulawulo oluchanekileyo lokuhamba; Kwangaxeshanye, ukugcinwa rhoqo kunye nokugcinwa kweevalve zebhabhathane, ukujonga ukunxiba kwezitywina, ukuguquguquka kweeshafu zevalve, kunye nokutshintshwa kwamacandelo awonakele ngexesha elifanelekileyo yimilinganiselo ebalulekileyo yokuqinisekisa ukuba iivalve zebhabhathane zihlala zikwimeko entle yokusebenza kunye nolawulo oluchanekileyo lokuhamba.
