Amacandelo oomatshini bobunjineli bemigodi ye-Hydraulic valve cartridge yokulinganisa ivalve CBIG-LJN

Iivalve zoncedo lwe-pilot ziyafumaneka kwiindidi ezahlukeneyo zoqwalaselo. Ivalve yovavanyo yesakhiwo esiqhelekileyo esinamacandelo amathathu, enamacandelo amabini: ivalve yokulinga kunye nevalve engundoqo.

Ivalve yetaper pilot, umngxuma wokudambisa (umngxunya we-throttle osisigxina) kwi-spool yevalve engundoqo kunye noxinzelelo olulawula intwasahlobo kunye zenza umqhubi wesiqingatha sebhulorho yoxinzelelo oluyinxenye yolawulo olungalunganga lwengxelo, enoxanduva lokubonelela ngenqanaba eliphambili lomyalelo woxinzelelo emva kwevalve yokulinga. ulawulo loxinzelelo kwigumbi eliphezulu le-spool yevalve engundoqo. I-spool ephambili ngumthelekisi we-loop yolawulo oluphambili. Ubuso besiphelo esiphezulu busebenza njengomyalelo womyalelo we-spool engundoqo, ngelixa ubuso besiphelo esisezantsi busebenza njengomgangatho wokulinganisa uxinzelelo lwe-loop engundoqo kwaye lusebenza njengamandla empendulo. Umbane ophumelayo unokuqhuba i-spool, ulungelelanise ubungakanani be-port ephuphumayo, kwaye ekugqibeleni ufezekise injongo yokulawula nokulawula uxinzelelo loxinzelelo lwe-inlet P1.

Uhlobo lwe-YF uhlobo olunamacandelo amathathu olululo lwesakhiwo sevalvu yokuphola; 1-(- ivelufa yetaper (ivalve yokulinga); 2 - Isitulo seCone 3 - isigqubuthelo sevalvu; 4 - Umzimba weValve; 5 - umngxuma wokudambisa; 6 - undoqo wevalve; 7 - Engundoqo isihlalo se-8 - i-valve ephambili ye-9 - ukulawulwa koxinzelelo (i-valve ye-pilot) i-10 - ukulungisa i-screws;

Ukuqhekeka komsebenzi

Xa usebenza, uxinzelelo lwe-liquid lusebenza kumphezulu wokulinganisa uxinzelelo lwe-spool ephambili kunye ne-pilot spool ngaxeshanye. Xa i-valve ye-pilot ye-1 ingavulwa, i-oyile ayihambi kwigumbi le-valve, kwaye uxinzelelo olusebenza kwi-spool ephambili kumacala omabini lulingana, kodwa ngenxa yokuba indawo yoxinzelelo olusebenzayo lwecala eliphezulu likhulu kunendawo yoxinzelelo olusebenzayo. kwesiphelo esisezantsi, i-spool ephambili ikwindawo esezantsi phantsi kwesenzo samandla esiphumo, kwaye i-valve port ivaliwe. Xa uxinzelelo lokungena lunyuka ngokwaneleyo ukuze uvule ivalve yokulinga, ulwelo luqukuqela kumngxunya wokumanzisa kwispool yevalvu engundoqo kunye nevalve yokulinga ibuyele etankini. Ngenxa yesiphumo sokudambisa somngxunya wokudambisa, i-spool engundoqo iphantsi kweendlela eziphezulu kunye nezisezantsi zoxinzelelo lwamanzi azilingani, i-spool engundoqo inyuka phantsi kwesenzo somohluko woxinzelelo, ivula i-valve port, iqonde ukuphuphuma. , kwaye igcina uzinzo olusisiseko loxinzelelo. Uxinzelelo oluphuphumayo lunokulungelelaniswa ngokulungelelanisa intwasahlobo elawula uxinzelelo lwevalve yokulinga.
