Kukho iintlobo ezininzi kunye neentlobo ezinzimaiivalve, ikakhulu kubandakanywa iivalvu zesango, iivalvu zeglowubhu, iivalvu zeglowubhu, iivalve zebhabhathane, iivalve zeplagi, iivalve zebhola, iivalve zombane, i-diaphragm valves, iivalve zokujonga, iivalvu zokhuseleko, iivalvu zokunciphisa uxinzelelo, imigibe yomphunga kunye neevalvu zokuvala ngokukhawuleza, njl. zidla ngokusetyenziswa ivelufa yesango, ivelufa yeglowubhu, ivalve ye-throttle, ivalve yeplagi, ivalve yebhabhathane, ivalve yebhola, ivalve yokukhangela, ivalve yediaphragm.
1 Ivalve yebhabhathane
Ivalve yebhabhathane ngumsebenzi wokuvula nokuvala wepleyiti yebhabhathane unokugqityezelwa ngokujikeleza i-90° ijikeleze i-axis esisigxina kumzimba wevalvu. Ivalve yebhabhathane incinci ngobungakanani, ilula ngobunzima kwaye ilula kwisakhiwo, kwaye iqulathe kuphela iinxalenye ezimbalwa. Kwaye idinga kuphela ukujikeleza i-90 °; inokuvulwa kwaye ivalwe ngokukhawuleza, kwaye umsebenzi ulula. Xa ivalve yebhabhathane ikwindawo evuleleke ngokupheleleyo, ubukhulu bepleyiti yebhabhathane yeyona nto ixhathisayo xa i-medium iqukuqela kumzimba wevalve, ngoko ke ukuhla koxinzelelo okwenziwa yivalve kuncinci kakhulu, ngenxa yoko kuneempawu ezingcono zokulawula ukuhamba. Ivalve yebhabhathane yahlulwe yaba yilastiki ethambileyo yokutywina kunye nentsimbi eqinileyo yokutywina. Ivalve yokutywina ethambileyo, umsesane wokutywina unokufakwa kumzimba wevalve okanye uncanyathiselwe kumda wediskhi, ngokutywinwa kokusebenza kakuhle, okungasetyenziselwa ukugobhoza, imibhobho yofunxa ephakathi kunye nemithombo yeendaba eyonakalisayo. Iivalvu ezinamatywina entsimbi zinobomi obude kunezo zinamatywina anwebekayo, kodwa kunzima ukufezekisa ukutywinwa okupheleleyo. Ngokuqhelekileyo zisetyenziswa kwiimeko ezinotshintsho olukhulu lokuhamba kunye nokuhla koxinzelelo kwaye zifuna ukusebenza kakuhle kwe-throttling. Izitywina zentsimbi zinokuqhelana nobushushu obuphezulu bokusebenza, ngelixa izitywina ezilastiki zinesiphene sokunqandwa bubushushu.
2Ivalve yesango
Ivalve yesango ibhekisa kwivalve emzimba wayo wokuvula nokuvala (ipleyiti yevalvu) iqhutywa sisikhondo sevalvu kwaye ihla inyuka igudle umphezulu wokutywina wesihlalo sevalvu, enokudibanisa okanye inqumle indlela yolwelo. Xa kuthelekiswa nevalve yeglowubhu, ivalve yesango inomsebenzi ongcono wokutywina, ukunganyangeki kwamanzi, umzamo omncinci wokuvula nokuvala, kwaye inomsebenzi othile wohlengahlengiso. Yenye yeevalvu zebhloko ezisetyenziswa ngokuqhelekileyo. Ukungalungi kukuba ubukhulu bukhulu, isakhiwo sinzima ngakumbi kuneso sivalo seglobhu, indawo yokutywina kulula ukuyinxiba, kwaye akulula ukuyigcina. Ngokuqhelekileyo, ayifanelekanga ukubethelwa. Ngokwendawo yomsonto kwisiqu sevalve yesango, yahlulwe ibe ziindidi ezimbini: uhlobo lwentonga evulekileyo kunye nodidi lwentonga emnyama. Ngokweempawu zesakhiwo sesango, inokwahlulwa ibe ziindidi ezimbini: uhlobo lwe-wedge kunye nohlobo oluhambelanayo.
3 Khangela ivalve
Ivalve yokukhangela ivalve enokuthi ithintele ngokuzenzekelayo ukuphuma kolwelo. I-valve ye-valve ye-valve yokutshekisha ivuliwe phantsi kwesenzo soxinzelelo lwe-fluid, kwaye i-fluid igeleza ukusuka kwicala lokungena ukuya kwicala lokuphuma. Xa uxinzelelo kwicala lokungena lisezantsi kunolo kwicala lokuphuma, i-valve flap iya kuvala ngokuzenzekelayo phantsi kwesenzo somohluko woxinzelelo lwe-fluid, ubunzima bayo kunye nezinye izinto zokuthintela ulwelo ukuba luhambe ngasemva. Ngokwesakhiwo, inokwahlulwa ibe yivalve yokukhangela yokuphakamisa kunye nevalve yokujonga i-swing. Uhlobo lokuphakamisa lunomsebenzi ongcono wokutywina kunye nokumelana nolwelo olukhulu kunohlobo lwe-swing. Kwizibuko lokufunxa lombhobho wokufunxa wempompo, ivalve esezantsi kufuneka ikhethwe. Umsebenzi wayo kukugcwalisa umbhobho wokungena wempompo ngamanzi ngaphambi kokuba uqale umpompo; gcina umbhobho wokungena kunye nomzimba wempompo uzaliswe ngamanzi emva kokuba umpompo umisiwe, ukuze ulungiselele ukuqalisa kwakhona. Ivalve esezantsi ifakelwa kuphela kumbhobho othe nkqo wempompo yokungena, kwaye ophakathi uhamba ukusuka ezantsi ukuya phezulu.
4 Ivalve yeglowubhu
Ivalve yeglowubhu yivalve evalekileyo eyehlayo, kwaye ilungu elivulayo nelivalayo (ivalve) liqhutywa sisikhondo sevalve ukuya phezulu nasezantsi ecaleni kwe-axis yesitulo sevalvu (umphezulu wokutywina). Xa kuthelekiswa nevalve yesango, inokusebenza kakuhle kokulungelelaniswa, ukusebenza kakubi kokutywinwa, isakhiwo esilula, ukwenziwa kunye nokugcinwa ngokufanelekileyo, ukuxhathisa okukhulu kwamanzi kunye nexabiso eliphantsi.
5 Ivalve yebhola
Indawo yokuvula neyokuvala yevalve yebhola yingqukuva enesetyhula emngxunyeni, kwaye ingqukuva ijikeleza ngesiqu sevalve ukuqonda ukuvuleka nokuvalwa kwevalve. I-valve yebhola inesakhiwo esilula, ukutshintshwa ngokukhawuleza, ukusebenza kakuhle, ubungakanani obuncinci, ubunzima bokukhanya, iindawo ezimbalwa, ukuchasana kwamanzi amancinci, ukusebenza kakuhle kokutywinwa kunye nokugcinwa okufanelekileyo.
6 Ivalve yomqala
Ubume bevalve ye-throttle ngokusisiseko buyafana naleyo yevalve yeglowubhu ngaphandle kwediski yevalve. I-disc ye-valve iyinxalenye ye-throttling, kwaye iimilo ezahlukeneyo zineempawu ezahlukeneyo. Ububanzi besihlalo se-valve akufanele bube bukhulu kakhulu, kuba ukuphakama kokuvula kuncinci. Izinga lokuhamba okuphakathi liyenyuka, ngoko Ikhawulezisa ukhukuliseko lwediski yevalvu. I-valve ye-throttle inemilinganiselo emincinci, ubunzima obulula kunye nokusebenza kakuhle kohlengahlengiso, kodwa ukuchaneka kokulungelelaniswa akuphezulu.
7 Ivalve yokuplaga
Ivalve yeplagi isebenzisa umzimba weplagi onomngxuma ophumelayo njengenxalenye yokuvula neyokuvala, kunye nomzimba weplagi ujikeleza ngesikhondo sevalve ukuqonda ukuvuleka nokuvalwa kwevalve. I-valve yeplagi ineenzuzo zesakhiwo esilula, ukutshintsha ngokukhawuleza, ukusebenza kakuhle, ukuchasana kwamanzi amancinci, iindawo ezimbalwa kunye nobunzima obulula. Kukho iivalvu zeplagi ezinendlela ethe tye, enendlela-ntathu kunye neendlela ezine. I-valve yeplagi echanekileyo isetyenziselwa ukunqumla i-medium, kwaye i-valve yeplagi yeendlela ezintathu kunye ne-four-way isetyenziselwa ukutshintsha indlela ephakathi okanye ukwahlula phakathi.
8 Ivalve ye-diaphragm
Indawo evulayo nevalayo yevalve ye-diaphragm yirabha diaphragm, edityaniswe phakathi komzimba wevalve kunye nesivalo sevalvu. Inxalenye ephakathi ephumayo ye-diaphragm igxininiswe kwi-valve stem, kwaye umzimba wevalve ufakwe irabha. Ekubeni i-medium ingangeni kwi-cavity yangaphakathi ye-valve cover, i-valve stem ayifuni ibhokisi yokufaka. Ivalve ye-diaphragm inesakhiwo esilula, ukusebenza kakuhle kokutywinwa, ukugcinwa lula kunye nokuchasana kwamanzi amancinci. Iivalvu ze-diaphragm zahlulwe ngohlobo lwe-weir, uhlobo oluthe tye, uhlobo lwe-angle ekunene kunye nohlobo lokuhamba ngokuthe ngqo.
