Ivalve ye-hydraulic balance valve Excavator hydraulic cylinder valve core PVDB-LWN

Umgaqo-nkqubo wokusebenza wevalvu esebenza ngokuthe ngqo

1. Ibhalansi yoxinzelelo: umzimba wevalve yevalve esebenza ngokuthe ngqo uxhotyiswe ngekiti yokutywina. Xa uxinzelelo ludlula ixabiso elimiselweyo lenkqubo, ikiti yokutywina iya kuvelisa amandla, iqhube i-spool kunye nentonga yoxinzelelo ukuya kwelinye icala;
2. Umgaqo wokunyakaza: Ukuba uxinzelelo luphezulu kunexabiso elimiselweyo lenkqubo, intonga yoxinzelelo iya kudlula kumzimba we-valve, ukwenzela ukuba i-spool iqhutywe ivuleke, kwaye inxalenye yeoli ye-hydraulic ikhutshwe kwi-port ephuphumayo;
3. Umgaqo wokulawula: Xa uxinzelelo lungaphantsi kwexabiso elimiselweyo lenkqubo, intonga yoxinzelelo iya kutsalwa yipiston kwaye ibuyele ekubuyiseleni ngexesha, ukwenzela ukuba i-valve core iphinde ibanjwe, ukwenzela ukuba ugweme ukuhamba kweoli ye-hydraulic ngaphandle kwezibuko eziphuphumayo kunye nokukwazi ukuqhawula inkqubo;

Iimpawu zevalve yokunceda esebenza ngokuthe ngqo
1. Ukuphendula ngokukhawuleza: i-valve yokunceda ngokuthe ngqo ithatha umgaqo wokulinganisela uxinzelelo, onokusabela ngokukhawuleza kwiinguqu kweso sihlandlo;
2. Ikhuselekile kwaye inokwethenjelwa: i-valve yokunceda ngokuthe ngqo inokuphinda isebenze ngokuzinzile ngaphakathi kwinqanaba elikhulu loxinzelelo, elinokukhusela ngokufanelekileyo ukhuseleko lwenkqubo;
3. Ukugcinwa okulula: ivalve yokunceda esebenza ngokuthe ngqo ifuna ukuvavanywa rhoqo, akukho kutshintshwa rhoqo kweengxenye ezifunekayo, kwaye ukugcinwa kulula;
4. Ingxolo ephantsi: Ivalve yokunceda esebenza ngokuthe ngqo ithatha umgaqo wokulawula ukulinganisela koxinzelelo, ukulawula inkqubo yokuvala ithambile ngakumbi, inokunciphisa ingxolo, ifanele indawo yengxolo ephezulu.
