Ivalve yokulinganisa ivalve esebenza ivelufa ye-CBGG-LJN

I-valve yokulinganisa i-cartridge ye-port-port yi-valve eguquguqukayo (i-pilot-oil-assisted opening). Ivumela ukuhamba okukhululekileyo kwe-oyile ukusuka kwizibuko le-2(inlet) ukuya kwizibuko 1(izibuko lomthwalo) : ukuqukuqela kweoyile kumisiwe.
Hambisa (umlomo 1 ukuya emlonyeni 2) de kube uxinzelelo lomqhubi, oluhambelana ngokungafaniyo noxinzelelo lomthwalo, lusebenza emlonyeni wesi-3 ngaphambi kokuvula. Ukulungelelaniswa kwe-port ye-valve yokulinganisa kuyisiphumo sesenzo esiphindwe kabini soxinzelelo lomthwalo kunye noxinzelelo lomqhubi, olwenza "i-inverse pilot pressure ratio": umthwalo wokukhanya ufuna ukuvuleka koxinzelelo lomqhubi ukuba ube mkhulu kunomthwalo, ukuphucula ukuzinza. kunye nolawulo olungcono lwentshukumo.
Umsebenzi wokulawula ukunyakaza kwe-valve yokulinganisa ubonakaliswe ekugcineni uxinzelelo olufanelekileyo lomthwalo kwi-valve yokubuyisela nangona umthwalo ugqithisekile. Xa i-valve yebhalansi ivaliwe, ukuvuza kwayo kuncinci kakhulu (kufutshane ne-zero). Izihlalo ezigudileyo ezingaphawulwanga kunye nobutyobo obucolekileyo kwi-oyile (nokuba ioyile "ecocekileyo" kakhulu) zenza itywina kwimizuzu yokuvala ivalve ukuphelisa ukuvuza. Ulawulo lokunciphisa umthwalo oguqukayo lunokuphunyezwa ngokukhetha ivalve efanelekileyo yokubuyisela umva kunye noyilo lwesekethe. Kwangaxeshanye, umsebenzi wokuphuphuma kwezibuko 1(izibuko lomthwalo) kwizibuko 2(inlet) lidityanisiwe ukunqanda uxinzelelo olugqithisileyo kunye nobushushu obugqithisileyo bomthwalo. I-valve ye-valve yokulinganisa i-port ene-countercurrent check valve ifanelekile ukuba isebenze phantsi komthwalo oqhubekayo, apho i-valve yoxinzelelo kufuneka ibekwe ngamaxesha e-1.3 yoxinzelelo lomthwalo oqhubekayo (uxinzelelo lwe-3 lwe-port alubalwa). Ukusebenza kwevalve yekhatriji elungeleleneyo kungoku kulandelayo:
Ukuvuza kuncinci kwi-cutoff. Kwixabiso elimiselweyo le-85%, ukuvuza okuphezulu okuncinci kungama-5 amaconsi / min (0.4cc / min).
I-hysteresis yevalve yokunceda nayo incinci xa izinga lokuhamba litshintsha kakhulu.
Ukuchasana okunamandla kungcoliseko lweoyile. Uxinzelelo lokusebenza ukuya kuthi ga kwi-5000psi (350bar). Isantya sokuhamba 120gpm(460L/min)
Izikrufu ezilungelelanisiweyo zingasetyenziselwa ukunciphisa uxinzelelo olubekiweyo: xa uxinzelelo lomqhubi lungonelanga, i-screw yokukhululwa ye-emergency manual ingasetyenziswa.
