Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0014] Such as figure 1 As shown, an oil-controlled multifunctional valve includes a valve body 1. The valve body 1 is provided with a basic layer oil chamber and a top oil chamber. The top oil chamber is placed on the basic layer oil chamber. The oil inlet passage 2, the total return oil passage 3, the first oil passage 4 and the second oil passage 5, the total inlet oil passage 2 and the first oil passage 4 are connected, the connection between the first oil pass...

Abstract

The invention discloses an oil control multifunctional valve. The oil control multifunctional valve comprises a valve body which is internally provided with a basic layer oil cavity and a top oil cavity; the basic layer oil cavity is provided with a main oil inlet line, a main oil returning line, a first oil line and a second oil line, and a first oil line oil inlet valve port and a second oil line oil inlet valve port communicate with the main oil inlet line; the basic layer oil cavity is further internally provided with a main safety valve oil line; the first oil line and the second oil line are each provided with two working oil ports, and each working oil port is connected with a corresponding oil inlet cavity; the basic layer oil cavity is provided with three oil port auxiliary valves, and auxiliary valve oil inlet lines of the three oil port auxiliary valves communicate with the three working oil ports correspondingly; and auxiliary valve oil returning oil lines communicate with the main oil returning line. The oil control multifunctional valve is compact in structure, large in flow capacity, good in high-temperature stability and complete and diversified in function.

Description

technical field [0001] The invention relates to the field of hydraulic pressure, in particular to an oil control multifunctional valve. Background technique [0002] At present, the multi-way valve with integral structure, its internal oil circuit form continues to use the valve body with partly sectional structure, but there are still the following two disadvantages: one is small in size and light in weight. Although the cost is reduced, the structure It is too simple and lacks some necessary functions; the other function is relatively complete, but the structure is complex and unreasonable, and at the same time it is large in size, heavy in weight and high in cost. The problem of the road valve reduces some manufacturing costs, but none of them have the advantages of small size and multiple functions at the same time, so they are not applicable. Therefore, there is an urgent need for an oil control multifunctional valve that is small in size, light in weight, simple in pr...
