Isilawuli esilingwayo se-CBBC-LAN Ivalve enkulu yokulinganisa ukuhamba

     Umgaqo osebenzayo wevalve yokuhamba

I-valve ejikelezayo luhlobo lwezixhobo zokulawula ukulawula ukuhamba kwamanzi, umgaqo wayo wokusebenza kukulungelelanisa ubungakanani bokuhamba ngokutshintsha indawo yokuhamba kombhobho. Ivalve yokuqukuqela isetyenziswa kakhulu kwinkqubo yokuhanjiswa kwehydraulic kwaye idlala indima ebaluleke kakhulu. Amacandelo aphambili evalve yokuqukuqela aquka umzimba wevalvu, izinto ezilawulayo (ezifana nespool, idiskhi yevalve, njl. njl.) kunye ne-actuator (efana ne-electromagnet, i-hydraulic motor, njl.). Iindidi ezahlukeneyo zeevalve zokuhamba zikwahluke kwisakhiwo, kodwa umgaqo wabo wokusebenza uyafana.
Umgaqo osebenzayo we-valve yokuhamba unokwahlulwa ngokulula kwiinkqubo ezimbini: ukutshintshwa kwendawo yokulawula kunye nokuhamba kwe-spool / disc.

indima yevalve yoncedo
I-1, impembelelo yoxinzelelo oluqhubekayo: kwi-quantitative pump throttling regulation system, ipompo yobungakanani inikeza ukuhamba rhoqo. Xa uxinzelelo lwenkqubo lukhula, imfuno yokuhamba iyancipha. oku
Xa ivalve yokhuseleko ivuliwe, ukuhamba okugqithisileyo kubuyiselwa kwitanki ukuze kuqinisekiswe ukuba uxinzelelo lwe-inlet yevalve yokhuseleko, oko kukuthi, uxinzelelo lokuphuma kwempompo, luhlala luhlala (i-valve port ihlala inoxinzelelo.
Avuleke amaza).
I-2, impembelelo yokulawula uxinzelelo: i-valve yokunceda idibaniswe kwi-series kwi-oil return circuit, i-valve yokunceda ivelisa uxinzelelo lwangasemva, kwaye ukuzinza kweendawo ezihambayo zanda.
I-3, inkqubo yokukhulula umsebenzi: i-port ekude yokulawula i-valve yokunceda ixhunywe kwi-solenoid valve ene-flow flow encinci. Xa i-electromagnetic ine-energy, i-remote control port yevalve yokhuseleko kunye netanki yamafutha ziqhagamshelwe
Idityanisiwe, ngeli xesha impompo ye-hydraulic ikhulula. Ivalve yokhuseleko isetyenziswa njengevalve yokhuseleko.
I-4, ukhuseleko lokhuseleko: xa inkqubo isebenza ngokuqhelekileyo, i-valve ivaliwe. Ukuphuphuma kuphela xa umthwalo udlula umda ochaziweyo (uxinzelelo lwenkqubo ludlula uxinzelelo olubekiwe)
I-valve iya kuvulwa, kunye nokukhuselwa komthwalo ogqithisiweyo, ukwenzela ukuba uxinzelelo lwenkqubo alusayi kunyuka (ngokuqhelekileyo uxinzelelo olusetiweyo lwevalve yokhuseleko luyi-10% -20 yenkqubo yoxinzelelo oluphezulu kunoxinzelelo oluphezulu lokusebenza)
ngamandla).
