Title
(EN) THREE WAY RATIO PRESSURE REDUCE CONTROL VALVE
(FR) SOUPAPE DE REGULATION A TROIS VOIES DE REDUCTION DE RAPPORT DE PRESSION
(ZH) 三通比例减压控制阀
Abstract
(EN) Three-way ratio pressure reducing control valve includes valve body, a cylindrical valve core bore in the valve body, a valve bore in the valve core bore. The assembled valve body and valve core form five cavities, the cavity Y, P, A, T, X, of which, the cavity A, the cavity P and the cavity T are communicated to port A, port P and port T separately; The cavity X in the valve core end is communicated with port T via oil path and the cavity Y is communicated with port A via oil path. The valve core has two control sides, including control side C1 located between the cavity A and the cavity P and control side C2 between the cavity A and the cavity T. The present invention provides three-way ratio pressure reducing control valve which can control pressure change between port P and port T through two regulatable throttling control sides. The present invention can solve the question about that the pressure can only switch in the max/least state but the pressure of the middle state can not be controlled.
(FR) La présente invention concerne une soupape de régulation à trois voies de réduction de rapport de pression qui comprend un corps de soupape, un alésage cylindrique de pièce intérieure de soupape dans le corps de soupape et un alésage de soupape dans l’alésage de pièce intérieure de soupape. Les corps de soupape et pièce intérieure de soupape assemblés forment cinq cavités, les cavités (Y), (P), (A), (T) et (X), dont la cavité (A), la cavité (P) et la cavité (T) sont en communication avec l’orifice (A), l’orifice (P) et l’orifice (T) séparément. La cavité (X) dans l’extrémité de pièce intérieure de soupape est en communication avec l’orifice (T) par l’intermédiaire d’un passage d’huile et la cavité (Y) est en communication avec l’orifice (A) par l’intermédiaire d’un passage d’huile. La pièce intérieure de soupape comporte deux côtés de régulation, comprenant un côté de régulation (C1) positionné entre la cavité (A) et la cavité (P) et un côté de régulation (C2) entre la cavité (A) et la cavité (T). La présente invention prévoit une soupape de régulation à trois voies de réduction de rapport de pression qui peut réguler le changement de pression entre l’orifice (P) et l’orifice (T) grâce à deux côtés de régulation d’étranglement pouvant être ajustés. La présente invention peut résoudre le problème concernant le fait que la pression peut seulement être changée dans un état maximum ou minimum mais que la pression d’un état moyen ne peut pas être régulée.
