Abavelisi beevalvu zokutshekisha bakholelwa ukuba iivalvu eziqhelekileyo zokutshekisha zivale ngokukhawuleza kwaye ziqhelene nehamile yamanzi, okukhokelela ekunyukeni ngokukhawuleza koxinzelelo, umonakalo kwimibhobho kunye nezixhobo kunye nengxolo enkulu.Ivalve yokujonga i-miniature ecothayo yokuvala isombulula iingxaki ezibangelwa ukuvalwa ngokukhawuleza kweevalvu eziqhelekileyo zokujonga.Ukusetyenziswa kunikezelo lwamanzi ngokuthe ngqo kunye neenkqubo zokuhambisa amanzi kumashishini oshishino kunye nemigodi kunye nezakhiwo eziphakamileyo, kunokunciphisa ukwenzeka kwesando samanzi kunye nesando samanzi kunye nokufezekisa umphumo wokuvala ngokukhuselekileyo.
1. Iimpawu zesakhiwo sevalve yokujonga i-micro-resistance evala ngokucothayo:
I-valve enye ifakwe phambi kwevalve, kwaye enye i-valve ifakwe emva kwevalve, ekulungele ukugcinwa.Faka isihluzo phambi kwevalve ukukhusela ukungcola kwindlela yokubhobhoza ekungeneni kwivalve yokutshekisha.Abavelisi bevalve yokukhangela bakholelwa ukuba ivalve yokujonga ukuvala ngokucothayo kufuneka ifakwe ngokuthe tye.Ukuba i-valve ifakwe equleni, kufuneka kubekho indawo yokugcina.Ivalve yokukhupha ngokuzenzekelayo kufuneka ifakwe kumbhobho ngokweenkcukacha ezifanelekileyo ukuqinisekisa ukuhamba okuqhubekayo koluhlu lwamanzi.
2. Umgaqo osebenzayo wevalve yokujonga i-micro-resistance evala ngokucothayo:
Xa impompo yamanzi iqaliswa: umenzi wevalve yokukhangela ukholelwa ukuba uxinzelelo kwi-valve inlet ibangela ukuba i-disc yevalve ivuleke ngokukhawuleza ngokuchasene ne-spring force, kwaye i-medium kwi-inlet ye-valve enkulu ingena kwigumbi eliphezulu le-diaphragm ngevalve yenaliti. kunye nevalve yokukhangela.Lungisa ukuvuleka kwevalve yenaliti, ukwenzela ukuba i-medium engena kwigumbi eliphezulu le-diaphragm isebenze kwipleyiti yoxinzelelo lwe-diaphragm, kwaye i-reaction force yenziwa kwi-disc yevalve ukuqinisekisa ukuba i-disc yevalve ivulwa ngokucothayo.Lungisa ukuvulwa kwevalve yenaliti kwi-inlet ye-valve engundoqo, lawula isantya sokuvula i-valve, kwaye uqinisekise ukuba ixesha lokuvula i-valve enkulu lide kunexesha lokuqala le-motor yempompo, ukuze impompo iqalise. phantsi komthwalo olula kwaye uthintele i-motor ukuqala okwangoku ukuba ibe nkulu kakhulu.
Xa umpompo wamanzi ucinyiwe: umenzi we-valve yokutshekisha ukholelwa ukuba uxinzelelo kwi-valve inlet ngokukhawuleza luyancipha, kwaye i-valve flap iya kuvala ngokukhawuleza phantsi koxinzelelo kwindawo yokuphuma, okubangelwa ukunyuka ngokukhawuleza koxinzelelo kwi-valve outlet.Ngeli xesha, ihamile yamanzi kulula ukwenzeka, ebangela umonakalo kwipayipi kunye nezixhobo ezisemva kwevalve, kwaye ivelise ingxolo eninzi.
Umenzi wevalve yokukhangela ukholelwa ukuba ngenxa yokuba inkqubo yokubuyisela ifakwe ekupheleni kwevalve, i-medium emva kokuba ivalve ingena kwigumbi eliphezulu le-diaphragm ngevalve yebhola.Ngenxa yomsebenzi wokutshekisha we-valve yokutshekisha, i-medium ayikwazi ukungena kwi-inlet end, kwaye igumbi elingaphantsi le-diaphragm lizaliswe ngokuphakathi.Nangona uxinzelelo oluphakathi kwigumbi eliphezulu lukhuthaza ukuvala i-valve flap, indawo ephakathi kwigumbi elisezantsi ayinakukhutshwa ngokukhawuleza phantsi kwesenzo sokugobhoza komngxuma omncinci wesihlalo se-diaphragm, okukhokelela kwinkqubo ye-buffering. isantya sokuvala i-valve flap kwaye ifezekisa ukuvala okucothayo.Isiphumo sisimumu sithintela isenzeko sehamile samanzi.Ngokulungelelanisa ukuvuleka kwevalve yebhola, isantya sokuvala sediski yevalve (oko kukuthi ixesha lokuvala levalve) linokulawulwa ngokufanelekileyo.
Umenzi wevalve yokukhangela ukholelwa ukuba i-valve yokukhangela i-micro-cocoing-evala ineempawu zobuchwepheshe zokuvula ngokukhawuleza kunye nokuvalwa okucothayo kunye nokuphelisa isando samanzi, esiqaphela ukuqala komthwalo wempompo kunye nokuthintela ukwenzeka kwehamile yamanzi xa impompo. iyekile.Emva kokuba injini yempompo iqalisiwe, ivalve iya kuvula ngokuzenzekelayo kwaye ivale ngokwenkqubo yokusebenza yempompo.Ivalve yokukhangela ibhekisa kwivalvu evula ngokuzenzekelayo kwaye ivale i-valve flap ngokuqukuqela okuphakathi ngokwawo ukuthintela ukubuya ngasemva kwesiphakathi.
Khangela abavelisi be-valve bakholelwa ukuba i-valve yokutshekisha i-valve ezenzekelayo, kwaye umsebenzi wayo oyintloko kukuthintela umva we-medium, ukuthintela ukujikeleza okujikelezayo kwepompo kunye ne-motor drive, kwaye ukhulule i-medium kwi-container.Iivalvu zokukhangela zingasetyenziswa kwimibhobho yokubonelela ngeenkqubo ezincedisayo apho uxinzelelo lunokwenyuka ngaphezu koxinzelelo lwenkqubo.Iivalve zokujonga zinokwahlulwa zibe ziivalve zokujonga ujingi (ezijikelezayo ngokweziko lomxhuzulane) kwaye ziphakamise iivalvu zokujonga (zihamba nge-axis).
