Pati Excavator PC300-5 PC400-5 Kontwòl Main Valv 709-90-52203 Valv Sekou

Yon valv sekou pou Excavator konprann yon tèt leve 11, yon bobin valv prensipal 12, yon manch prensipal tiyo 13, yon bobin valv pilòt 14, yon presyon reglemante sezon prentan 15 ak yon manch rad valv pilòt la. The main valve spool 12 is arranged inside the main valve sleeve 13, the main valve spool 12 is provided with a lifting head 11 and a pilot valve sleeve, and the pilot valve sleeve is provided with a pilot valve spool 14. The pilot valve sleeve is a two-stage split structure, composed of a valve body 16 and a valve cover 17, the valve body away from the valve cover end is arranged in the main valve core, the Kò valv tou pre fen kouvèti a valv yo te tounen nan fòme yon bòs 18, ak bòs nan travay la nan manch rad la valv prensipal yo bay ak yon Groove, de limit la blocage konstitye estrikti nan limit. Lè estrikti a se nan itilize, paske se manch rad la valv pilòt divize an de pati kò valv 16 ak valv kouvri 17, se manch valiz prensipal la 13 yo bay ak yon Groove, se kò a valv bay ak yon bòs 18, ki se itilize yo ranje kò a valv 16 radyal, nwayo a. Konte sou siyon yo sou manch rad la valv prensipal yo limite kò a valv axially ak radyo, ak Lè sa a, vis bouchon an valv nan manch rad la valv prensipal ak peze kò a valv yo ranje kò a valv, ak Lè sa a, ka valv la sekou dwe itilize nòmalman.

1. Yon valv sekou Excavator gen ladan yon tèt leve (11), yon bobin valv prensipal (12), yon manch valv prensipal (13), yon bobin valv pilòt (14), yon presyon prentan reglemante (15) ak yon manch rad valv pilòt la. Se bobin nan valv prensipal (12) ranje andedan manch rad la valv prensipal (13), ak bobin nan valv prensipal (12) yo bay ak yon tèt leve (11) ak yon manch rad valv pilòt la. The pilot valve sleeve is provided with a pilot valve core (14), which is characterized in that the pilot valve sleeve is a two-stage split structure, composed of a valve body (16) and a valve cover (17), the valve body (16) away from the valve cover (17) one end is arranged in the main valve core (12), The valve body (16) near the valve cover (17) - end is internally connected with the main Valv manch (13) atravè yon estrikti limite.
2. Dapre reklamasyon an 1, se yon valv sekou Excavator karakterize nan ki kò a valv (16) tou pre kouvèti a valv (17) fen yo te tounen soti nan fòme yon bòs (18), ak bòs nan travay la bay ak yon Groove andedan manch lan valv prensipal (13), ak de limit yo kranpon konstitye estrikti nan limit.
The utility model discloses a relief valve for an excavator, including a lifting head, a main valve core, a main valve sleeve, a pilot valve core, a pressure regulating spring and a pilot valve sleeve, the main valve core is arranged inside the main valve sleeve, the main valve core is provided with a lifting head and a pilot valve sleeve, the pilot valve sleeve is provided with a pilot valve core, which is characterized in that the Pilòt manch valv se yon estrikti de-etap fann. Konpoze de yon kò valv ak yon kouvèti valv, se kò a valv lwen fen nan kouvèti valv ranje nan nwayo a valv prensipal, kò a valv tou pre fen a kouvèti valv nan estrikti a limit ak koneksyon an manch prensipal valv entèn yo. Modèl la sèvis piblik divize manch rad la valv pilòt nan yon kò valv ak yon kouvèti valv, kidonk diminye longè a nan kavite anndan an nan manch rad la valv pilòt, amelyore presizyon nan pwosesis nan pati nan kontak ant manch rad la valv pilòt ak nwayo a valv pilòt, ak ensi amelyore estabilite nan valv la sekou.
