Iyakwazi ukujonga iivalvu ukunqanda ukuguqulwa kwempompo

Khangela iivalvuinokuthintela ngempumelelo ukuguqulwa kwempompo. Umgaqo ongundoqo kukuxhomekeka kumahluko woxinzelelo lwe-fluid ukuze ufezekise ukuqhutywa kwendlela enye kunye ne-reverse cutoff. Xa impompo isebenza ngokuqhelekileyo, ukuhamba phambili kwamanzi kutyhala i-disc ye-valve ukuvula, kwaye i-medium idlula kakuhle; Xa ipompo iyeka ngokukhawuleza okanye uxinzelelo lwenkqubo aluqhelekanga, lubangela ukuba ulwelo lujikeleze ngasemva, i-disc ye-valve ivala ngokukhawuleza phantsi komxhuzulane wayo, amandla entwasahlobo, okanye uxinzelelo lwe-fluid reverse, luvalela indlela yokubuyela umva. Eli nqaku lenza isixhobo esiphambili sokukhusela iimpompo kunye neenjini zokuqhuba.

Ukuthatha inkqubo yempompo yamanzi njengomzekelo, ukuba akhangela ivalveayifakwanga, xa umpompo wamanzi uyeka ngenxa yokungaphumeleli kwamandla okanye ukungasebenzi kakuhle, uxinzelelo olungaphakathi kwimpompo luyanyamalala, kwaye amanzi aphezulu axhunywe kwi-outlet aya kubuyela kumpompo kwicala elichaseneyo, etyhala i-impeller ukuba ibuyele umva. Ukujikeleza okubuyela umva akubangeli kuphela ukukhulula i-impeller kunye nokunxiba komkhono we-shaft, kodwa kunokukhokelela kumthwalo omninzi wemoto kunye nokudinwa, nto leyo ebeka isoyikiso esibi kukhuseleko lwezixhobo. Emva kokufaka i-valve yokutshekisha, ukuhamba kwamanzi okujikelezayo kuya kubangela ukuba i-disc ye-valve ivalwe ngokukhawuleza, ukunqumla umjelo ojikelezayo ojikelezayo, ngaloo ndlela ugweme umonakalo kumzimba wempompo ngenxa yokujikeleza umva.

I-anti reverse effect yekhangela iivalveinxulumene ngokusondeleyo kuhlobo kunye nendawo yokufakela. Iivalve zokujonga i-Swing zinokumelana nokuhamba okuphantsi ngenxa yokujikeleza kwe-disc ye-valve ejikeleze i-axis, ezenza zilungele imibhobho emikhulu, ephakathi kunye nephantsi yoxinzelelo; Phakamisa iivalvu zokujonga ukuphumeza ukutywinwa ngokutyibilika idiski yevalve ecaleni kwe-axis, ngokusebenza ngcono kokutywina. Nangona kunjalo, banokumelana nokuhamba okuphezulu kwaye basetyenziswa kakhulu kwi-diameter encinci kunye ne-high-pressure scenarios. Kungakhathaliseki ukuba luhlobo luni na, kuyimfuneko ukuqinisekisa ukuba isalathiso sofakelo siyahambelana nesikhokelo sokuhamba kombindi, kwaye inkxaso yombhobho izinzile ukuze isebenzise ngokupheleleyo umsebenzi wayo wokulwa ne-reverse.

Ukongeza, iivalve zokuhlola zinokuphinda zinciphise intshukumo yehamile yamanzi - xa i-disc yevalve ivala ngokukhawuleza, nangona kunokubakho uxinzelelo olufutshane loxinzelelo ngenxa ye-inertia yolwelo, amandla ayo atshabalalisayo anokuncitshiswa ngokukhetha uhlobo olufanelekileyo (njenge-axial flow check valves) okanye ukufaka izixhobo ze-buffering. Ngoko ke, ukufakela i-valve yokukhangela kwi-pump outlet akukona nje umlinganiselo oyimfuneko wokuthintela ukujikeleza umva, kodwa kunye nekhonkco elibalulekileyo lokuqinisekisa ukusebenza okukhuselekileyo kunye nokuzinza kwenkqubo yonke yamanzi.
