Ivalve ye-hydraulic balance valve Excavator ye-hydraulic cylinder valve core CKCB-XFN

Ukusetyenziswa okuhlanu kwevalve yokunceda

Inokuqulunqwa ngeenkqubo ezintathu zokulawula isantya sokubetha. Ukugqithisa kuvulwa kuphela xa umthwalo udlula umda ochaziweyo (uxinzelelo lwenkqubo ludlula uxinzelelo olubekiwe):1. Xa uxinzelelo lwenkqubo lukhula, oko kukuthi, uxinzelelo lwempompo luhlala luhlala (i-valve port ihlala ivula ngokuguquguquka koxinzelelo). Ivalve yoncedo ngokuqhelekileyo inezakhiwo ezibini, ezisetyenziselwa ukuvelisa uxinzelelo lwangasemva (umtya kwisekethe yeoli yokubuya) ukwenzela ukhuseleko lomthwalo ogqithisileyo, oya kunciphisa imfuno yokuqukuqela. Ivalve ye-Throttle ayinamsebenzi wempendulo engalunganga. I-valve ye-throttle kunye ne-valve yokutshekisha inokudibaniswa kwi-valve yendlela enye ye-throttle ngokufanayo, engakwazi ukuhlawulela ukungazinzi kwesantya okubangelwa ukutshintshwa komthwalo, ipompo yobungakanani inika izinga lokuhamba rhoqo, njengomlawuli woxinzelelo olude, njengoko ivalve yokulandelelana. Ivalve yoncedo isetyenziswa njengevalve yolawulo oluphezulu kunye noxinzelelo oluphantsi, ivalve ivaliwe, inkqubo yokulawula isantya se-oyile yokubuyisela isantya kunye nenkqubo yokulawula isantya sokutyhutyha, ngokuqhelekileyo kuphela ngezihlandlo apho umthwalo utshintsha kancinci okanye iimfuno zokuzinza kwesantya hayi phezulu: kwiivalvu zokothula, kwimpompo yobungakanani be-hydraulic system. Kwizicelo ezisebenzayo, i-valve ye-throttle ngokuqhelekileyo i-valve elawula ukuhamba kwamanzi ngokuguqula icandelo le-throttling okanye ubude: kwi-quantitative pump throttling regulation system, umsebenzi wokukhusela ukhuseleko uqinisekisa ukunyanzeliswa kwe-inlet ye-valve yokunceda, oko kukuthi, i-inlet. inkqubo yokulawula isantya sompompoza. Ukuze uxinzelelo lwenkqubo alusayi kunyuka (ngokuqhelekileyo i-valve yokumisela i-valve yokumisela uxinzelelo kunoxinzelelo oluphezulu lomsebenzi we-10% ukuya kwi-20%), i-valve yokunceda ngokuthe ngqo.
