In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of one-way valve, comprise valve body and spool, described spool is located in valve body, described valve body is cylindrical shape, described spool comprises opening jump ring, spring and valve, and described valve interior wall is provided with circular groove, and valve is located in circular groove, described opening jump ring is fastened in valve body, and described spring is located between valve and opening jump ring.
On described valve interior wall, be provided with side by side one group for placing the jump-ring slot of opening jump ring.
Cone match is passed through in one end of described circular groove and valve.
Described valve one end is provided with protruding cylinder, and spring one end is enclosed within on cylinder.
Described valve body two end part external diameter is greater than valve body middle part external diameter.
Described valve can be changed from taking out in valve body.
Described opening jump ring is provided with the spring fixed hole for fixing spring one end, and described valve is provided with the spring fixed groove for the fixing spring the other end.
One turns to pipe-line system, comprises the return tube that turns to pipe-line system, and described return tube is sebific duct, and one-way valve described above is located in sebific duct, and on described sebific duct excircle, corresponding valve body position is fastening by clip.
The present invention compared with prior art, has the following advantages:
Simple in structure, in valve body, can select the valve of various outer diameter, realize unidirectional and dual functions throttling, solve " hired roughneck " problem, can also solve steering system oil return abnormal sound problem simultaneously; When installation, fastening by clip in the direct sebific duct that valve body is located to steering system, low to fit dimension required precision, fixing reliable, it is convenient to assemble.

Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1 to Figure 3, this one-way valve, comprises valve body 2 and spool, spool is located in valve body 2, wherein, valve body 2 is cylindrical shape, and spool comprises opening jump ring 4, spring 5 and valve 6, on valve body 2 inwalls, be provided with circular groove 21, valve 6 is located in circular groove 21, is provided with side by side one group for placing the jump-ring slot of opening jump ring on valve interior wall, and opening jump ring 4 is fastened in the interior jump-ring slot of valve body, circular groove is the step of vertical valve body axis towards jump-ring slot one end, and the circular groove the other end is conical surface; Valve one end is the conical surface, and the other end is cylindrical body.
The conical surface of valve 6 and the conical surface of circular groove are suitable, and spring 5 is located between valve 6 and opening jump ring 4, and spring 5 is Compress Spring, and all the time in compressive state, the valve in valve body and spring position by opening jump ring, simple in structure.
Opening jump ring 4 is provided with the spring fixed hole 41 for fixing spring one end, and the cylinder of valve 6 is provided with the spring fixed groove 61 for the fixing spring the other end.Spring 5 two ends are fixed on the cylinder of opening jump ring and valve reliably, and installing/dismounting is all very convenient.
Opening jump ring 4 can be fixed in the jump-ring slot of diverse location by selection, or by changing the spring 5 of different model, realizes threshold values is regulated, and steering system back pressure is arranged and regulated, and is widely used.
Valve 6 can be changed from the interior taking-up of valve body 2, and the projection of the conical surface end margin of valve is in circular groove, and valve moves back and forth and undertaken spacingly by circular groove two ends along valve axis, prevents that pressure is excessive, and spool is caused to damage; After the relative valve axis of valve tilts, can in valve body, take out, the valve of replaceable various outer diameter as required, regulates the valve port of one-way valve, adapts to different vehicles, and throttle degree difference can effectively solve oil return abnormal sound problem.
Valve body 2 two end part external diameters are greater than valve body middle part external diameter, are convenient to carry out fitted seal with sebific duct 1.
As shown in Figure 4 and Figure 5, turn to pipe-line system, comprise the return tube that turns to pipe-line system, return tube is sebific duct 1, and one-way valve described above is located in sebific duct 1, and on sebific duct excircle, corresponding valve body position is fastening by clip 3.
Clip 3 is the electrodeless clip of monaural, and fixing reliable, it is convenient to assemble.When assembling, only valve body need be filled in sebific duct, be undertaken fastening by clip.
In valve body, can select the valve of various outer diameter, realize unidirectional and dual functions throttling.When valve open, in sebific duct, liquid flows to from A to B, selects various outer diameter valve, realizes throttling in various degree; When valve closing, B is stoped by valve to the liquid of anti-stream, stops reverse liquid to flow the impact to system.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present invention and technological scheme carry out; or without improving, design of the present invention and technological scheme are directly applied to other occasion, all within protection scope of the present invention.
