Ivalve yokukhulula Ivalve ye-excavator ye-solenoid yokulawula ivalve engundoqo 723-46-48100

I-valve yokunceda i-valve yokulawula uxinzelelo lwe-hydraulic, eyona nto idlala indima yokunciphisa uxinzelelo, ukulawulwa koxinzelelo, ukukhulula inkqubo kunye nokukhusela ukhuseleko kwizixhobo ze-hydraulic. Kwi-quantitative pump throttling regulation system, ipompo yobungakanani inikeza ukuhamba rhoqo, xa uxinzelelo lwenkqubo lukhula, imfuno yokuhamba iya kuncitshiswa, ngeli xesha i-valve yokunceda ivuliwe, ukwenzela ukuba ukuhamba okungaphezulu kubuyele kwitanki, ukuqinisekisa ukuba Uxinzelelo lwe-valve yokungena, oko kukuthi, uxinzelelo lokuphuma kwempompo luhlala luhleli. I-valve yokunceda idibaniswe ngokulandelelana kwisekethe ye-oyile yokubuya, kwaye ukuzinza kweendawo ezihambayo zoxinzelelo lwangasemva kwe-valve yokunceda kwanda. Umsebenzi wokukhulula wenkqubo kukudibanisa i-valve ye-solenoid kunye ne-flow flow encinci kwi-series kwi-remote control port ye-valve yokunceda. Xa i-electromagnetic ine-energy, i-remote control port yevalve yokukhulula idlula kwitanki yamafutha. Ngeli xesha, ipompo ye-hydraulic ikhutshwe kwaye i-valve yokunceda isetyenziswe njenge-valve yokukhulula. Umsebenzi wokukhusela ukhuseleko, xa inkqubo isebenza ngokuqhelekileyo, i-valve ivaliwe, kuphela xa umthwalo udlula umda ochaziweyo, ukugqithisa kuvulwa, kwaye ukukhuselwa kokugqithiswa kwenziwa, ukwenzela ukuba uxinzelelo lwenkqubo alusayi kwandiswa.

Ukusetyenziswa okuphambili kwevalve yokunceda ngala manqaku mabini alandelayo:

(1) Ulawulo loxinzelelo kunye nommiselo. Ukuba isetyenziswe kumthombo we-hydraulic oqulunqwe yimpompo yobungakanani, isetyenziselwa ukulungelelanisa ukukhupha uxinzelelo lwempompo ukuze kugcinwe uxinzelelo.

(2) Ukunciphisa uxinzelelo. Ukuba isetyenziswe njenge-valve yokukhusela, xa inkqubo isebenza ngokuqhelekileyo, i-valve yokunceda ikwimeko evaliweyo, kwaye iqala ukugqithisa kuphela xa uxinzelelo lwenkqubo lukhulu kunoxinzelelo olubekiwe, oludlala indima yokukhusela umthwalo ogqithiseleyo kwinkqubo.

Iimpawu zevalve yokukhulula zezi: ivalve kunye nomthwalo ufuna ukuhambelana, i-port yokunceda idibaniswe emva kwetanki yamafutha, kwaye uxinzelelo lokungena luyimpendulo engalunganga.

Nalu ujongo olukhawulezileyo kwivalve yokunceda esebenza ngokuthe ngqo:

Isivalufa esisebenza ngokuthe ngqo sisivalufa apho uxinzelelo lwehydraulic lomgca we-oyile ophambili osebenza kwi-spool lulungelelaniswa ngokuthe ngqo noxinzelelo olulawula amandla entwasahlobo. Njengoko kubonisiwe kuMfanekiso 1, i-valve yokunceda esebenza ngokuthe ngqo yenza izakhiwo ezintathu ezisisiseko ngenxa yeentlobo ezahlukeneyo zesakhiwo se-valve port kunye nomgangatho wokulinganisa uxinzelelo:

Sebenzisa isilayidi sohlobo lwevalve yokuphuphuma kwezibuko, isiphelo somlinganiselo woxinzelelo lobuso;

I-valve yohlobo lwe-taper port yokuphuphuma kwezibuko yamkelwe, kwaye indlela yokulinganisa uxinzelelo lobuso bokugqibela nayo yamkelwa.

Umphezulu wokulinganisa uxinzelelo kunye nomphetho we-throttle we-valve port zombini zisetyenziswa njenge-cones.

Nangona kunjalo, kungakhathaliseki ukuba luhlobo luni lwesakhiwo, i-valve yokunceda esebenza ngokuthe ngqo iqulethwe ngamacandelo amathathu, njengoxinzelelo olulawula intwasahlobo kunye nesibambo sokulawula uxinzelelo, i-valve ye-valve yokunceda kunye nomgangatho wokulinganisa uxinzelelo.
