Embodiment Construction

[0023] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0024] like Figure 1 to Figure 3 As shown, the one-way valve includes a valve body 2 and a valve core. The valve core is arranged in the valve body 2, wherein the valve body 2 is cylindrical, and the valve core includes an opening circlip 4, a spring 5 and a valve 6. An annular groove 21 is provided on the inner wall of the valve body 2, and the valve 6 is arranged in the annular groove 21. A group of circlip grooves for placing an opening circlip are arranged side by side on the inner wall of the valve body. In the spring groove, the end of the annular groove facing the spring groove is a step perpendicular to the axis of the valve body, and the other end of the annular groove is a conical surface; one end of the valve is a conical surface, and the other end is a cylinder.

[0025] The conic...

Abstract

The invention discloses a one-way valve and a steering pipeline system provided with the one-way valve. The one-way valve comprises a valve body and a valve element, wherein the valve element is arranged inside the valve body, the valve body is cylindrical and comprises an open clamp spring, a spring and a valve gate, an annular groove is formed in the inner wall of the valve body, the valve gate is arranged inside the annular groove, the open clamp spring is arranged inside the valve body in a clamping mode, and the spring is arranged between the valve gate and the open clamp spring. The steering pipeline system comprises an oil return pipe, and the oil return pipe is a rubber pipe. The one-way valve is arranged in the rubber pipe, and the position, corresponding to the valve body, on the outer circumference of the rubber pipe is fastened through a hoop. The one-way valve and the steering pipeline system provided with the one-way valve are simple in structure, can achieve double functions of one-way flowing and throttling, are fixedly reliably and are convenient and rapid to assemble.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a one-way valve and a steering pipeline system with the same. Background technique [0002] At present, passenger cars generally install a check valve at the oil inlet and outlet of the power steering gear to prevent the impact of the reverse fluid flow on the steering system and solve the "thug" phenomenon of the steering system. [0003] The existing one-way valve has a complex structure and a single function, and can only prevent reverse flow; the installation is cumbersome, and the requirements for the dimensional accuracy of the one-way valve and the oil inlet and outlet are relatively high, as well as the requirements for assembly and matching of the interface connection. , poor connection reliability. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a one-way valve an...
