I-hydraulic balance valve Excavator I-hydraulic cylinder valve core PVDB-LWN

Isimiso sokusebenza se-valve yokusiza esebenza ngokuqondile

1. Ibhalansi yokucindezela: umzimba wevalvu wevalvu yokusiza esebenza ngokuqondile ufakwe ikhithi yokuvala. Lapho ingcindezi idlula inani elibekiwe lesistimu, ikhithi yokuvala izokhiqiza amandla, iphushe i-spool kanye nenduku yokucindezela iye kolunye uhlangothi;
2. Umgomo wokunyakaza: Uma ingcindezi iphakeme kunenani elibekiwe lesistimu, induku yokucindezela izodlula emzimbeni we-valve, ukuze i-spool iphushwe ivuleke, futhi ingxenye yamafutha we-hydraulic ikhishwe echwebeni lokuchichima;
3. Umgomo wokulawula: Uma ingcindezi iphansi kunevelu ebekiwe yesistimu, induku yokucindezela izodonswa i-piston bese ibuyela ekubuyiseleni ngesikhathi, ukuze umgogodla we-valve uphinde unamathele, ukuze ugweme ukugeleza kukawoyela we-hydraulic ngaphandle kwechweba elichichimayo kanye nekhono lokunqamula uhlelo;

Izici ze-valve yokusiza esebenza ngokuqondile
1. Ukusabela okusheshayo: i-valve yokusiza esebenza ngokuqondile yamukela isimiso sokulinganisela kwengcindezi, engasabela ngokushesha ezinguqukweni zesenzakalo;
2. Iphephile futhi inokwethenjelwa: i-valve yokusiza esebenza ngokuqondile ingasebenza futhi ngokuzinzile ngaphakathi kwebanga elikhulu lokucindezela, elingavikela ngempumelelo ukuphepha kwesistimu;
3. Ukugcinwa okulula: i-valve yokusiza esebenza ngokuqondile idinga kuphela ukuhlolwa njalo, akukho ukushintshwa okujwayelekile kwezingxenye okudingekayo, futhi ukugcinwa kulula;
4. Umsindo ophansi: I-valve yokusiza esebenza ngokuqondile isebenzisa isimiso sokulawula ibhalansi yokucindezela, ukulawula inqubo yokuvala imnene kakhulu, inganciphisa umsindo, ifanele indawo yomsindo ophezulu.
