Ivalve ye-hydraulic balance valve Excavator hydraulic cylinder valve core CBGA-LBN

Umgaqo wokusebenza wevalve yokunceda

Ivalve yokunceda luhlobo lwevalve yokulawula uxinzelelo lweoyile, eyona nto idlala indima yokuphuphuma koxinzelelo rhoqo, ukulawulwa koxinzelelo, ukuguqulwa kwenkqubo kunye nokukhuselwa kokhuseleko kwizixhobo zoxinzelelo lweoyile.

Umgaqo wevalve yokunceda: Kwinkqubo yokulawula ipompo yokulinganisa, ipompo yobungakanani ibonelela ngesantya sokuhamba rhoqo, kwaye xa uxinzelelo lwenkqubo luncitshisiwe, imfuno yokuhamba iya kuncitshiswa.Okwangoku, i-valve yokunceda ivula i-valve yokulawula uxinzelelo kunye nokunciphisa i-valve ukwenza ukuhamba okugqithisileyo kubuyele kwi-tank kunye nokuqinisekisa ukunyanzeliswa kwe-inlet yevalve yokunceda.

Kwi-fixed pump throttling control system, ipompo esisigxina inikeza ukuhamba rhoqo.Xa uxinzelelo lwenkqubo luyancitshiswa, imfuno yokuhamba iya kuncitshiswa.Okwangoku, i-valve yokunceda ivuliwe, ukwenzela ukuba ukuhamba okugqithisiweyo kubuyele kwi-tank yokulawula uxinzelelo kunye ne-valve yokunciphisa uxinzelelo, ukuqinisekisa ukuba i-valve yokungena yoxinzelelo, oko kukuthi, uxinzelelo lokuphuma kwempompo luhlala luhleli (i-valve port i- ihlala ivulwa ngokuguquguquka koxinzelelo).

Umahluko phakathi kwevalve yokunceda kunye nevalve yokunciphisa uxinzelelo

Ivalve yokunceda kukuphepha ukukhawuleza kwenkqubo kunye nokuqinisekisa ukhuseleko.I-valve yokunciphisa uxinzelelo kukunyusa uxinzelelo lwenkqubo phantsi kwesiseko sokuqinisekisa ukuba inkqubo ayinayo isigaba.

I-1, i-valve yokunciphisa uxinzelelo isetyenziselwa ukunciphisa uxinzelelo lomgca wesebe lenkqubo yoxinzelelo lweoyile, ukwenzela ukuba uxinzelelo lwesebe luphantsi kwaye luzinzile kunoxinzelelo oluphambili lweoli, kuluhlu lokumisela uxinzelelo, i-valve yokunciphisa uxinzelelo. iphinde yacima njengevalve yoncedo.Kwaye ngokuhla kwenkqubo yoxinzelelo, xa uxinzelelo olubekwe yivalve yokunciphisa uxinzelelo lufikeleleke, ivalve yokunciphisa uxinzelelo ivuliwe, kwaye inxalenye yeoli iya kubuyela kwitanki (ngalo mzuzu, kukho uxinzelelo oluthile ioli ibuyele kwitanki, ukushisa kwamanzi kwitanki kuya kunyuka), uxinzelelo lwe-hydraulic lweli sebe aluyi kuvuka.Idlala indima yokunciphisa uxinzelelo kunye nokuzinzisa uxinzelelo kule ndlela!I-valve yokunceda ihluke, kwaye ifakwe kwi-outlet yepompo ukuqinisekisa ukuba uxinzelelo olupheleleyo lwenkqubo luzinzile kwaye alunyanzelisi.Ngoko ke, unendima yokhuseleko, ukulawulwa koxinzelelo, ukulawulwa koxinzelelo kunye nokunye!

I-2, i-valve yokunceda idla ngokuhambelana kwinkqubo yendlela yeentaba ukuze idlale indima yokulawula uxinzelelo, ukulawulwa koxinzelelo kunye nokunciphisa uxinzelelo, kunye ne-valve yokunciphisa uxinzelelo idla ngokulandelelana kwindlela yokudlala indima yokunciphisa uxinzelelo kunye nokunciphisa uxinzelelo. indlela yogcino loxinzelelo!

I-3, i-valve yokunceda ivalwe ngokuqhelekileyo, kodwa naxa inkqubo yoxinzelelo olugqithisileyo;Ivalve yokunciphisa uxinzelelo ivulekile kwaye icinezela i-channel emxinwa.

I-4, indima yevalve yokunceda ngummiselo woxinzelelo, ukuphuphuma, ukukhuselwa komthwalo.Ivalve yokunciphisa uxinzelelo iyanciphisa uxinzelelo, kwaye uxinzelelo kwindawo ethile yenkqubo yoxinzelelo lweoyile iyancitshiswa.Usetyenziso olwahlukileyo.Ngoko ke, ayinakutshintshwa.
