Existing one-way valve structures is complicated, and function singleness, can only prevent counter flow action; Operate loaded down with trivial details during installation, the dimension precision requirement of check valve and oil inlet and outlet place is higher, and docking port junction is assembled and coordinates requirement higher, connection reliability is poor.
Summary of the invention
Not enough for prior art, what technical problem to be solved by this invention was to provide a kind of check valve and had it turns to piping system, simple to reach structure, is convenient to the object installed.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of check valve, comprise valve body and spool, described spool is located in valve body, described valve body is round shape, described spool comprises opening jump ring, spring and valve, and described valve interior wall is provided with ring groove, and valve is located in ring groove, described opening jump ring is fastened in valve body, and described spring is located between valve and opening jump ring.
Described valve interior wall is provided with one group side by side for placing the jump-ring slot of opening jump ring.
The one end of described ring groove and valve passes through cone match.
Described valve one end is provided with protruding cylinder, and spring one end is enclosed within cylinder.
Described valve body both ends external diameter is greater than external diameter in the middle part of valve body.
Described valve can take out in valve body and change.
Described opening jump ring is provided with the spring fixed hole for fixing spring one end, and described valve is provided with the spring pickup groove for the fixing spring the other end.
One turns to piping system, comprises the used oil pipe turning to piping system, and described used oil pipe is sebific duct, and check valve described above is located in sebific duct, and on described sebific duct excircle, corresponding valve body position is by card band tightener.
The present invention compared with prior art, has the following advantages:
Structure is simple, can select the valve of various outer diameter in valve body, it is achieved the unidirectional dual-use function with throttling, solves " hired roughneck " problem, can also solve steering oil return abnormal sound problem simultaneously; During installation, being directly located in the sebific duct of steering by valve body by card band tightener, coordinating size accuracy requirement is low, and fixing reliable, it is convenient to assemble.

Embodiment
Compare 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 check valve, comprises valve body 2 and spool, spool is located in valve body 2, wherein, valve body 2 is round shape, and spool comprises opening jump ring 4, spring 5 and valve 6, valve body 2 inwall is provided with ring groove 21, valve 6 is located in ring groove 21, valve interior wall is provided with one group side by side for placing the jump-ring slot of opening jump ring, in opening jump ring 4 is fastened in valve body a jump-ring slot, ring groove is towards the step that jump-ring slot one end is vertical valve axis, and the ring groove the other end is conical surface; Valve one end is the conical surface, and the other end is right cylinder.
The conical surface of valve 6 and the conical surface of ring groove are suitable, and spring 5 is located between valve 6 and opening jump ring 4, and spring 5 is compression spring, is in compressed state all the time, and valve and spring in valve body are positioned by opening jump ring, and structure is simple.
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 pickup 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 by selecting to be fixed in the jump-ring slot of different positions, or by changing the spring 5 of different model, can realize valve value being regulated, steering back pressure arranged and regulate, be widely used.
Valve 6 can take out in valve body 2 and change, and the projection of the conical surface end margin of valve is in ring groove, and valve moves back and forth along valve axis and undertaken spacing by ring groove two ends, prevents pressure excessive, spool is caused damage; Valve opposite valve body axis can take out after tilting in valve body, and the valve of replaceable various outer diameter as required, regulates the valve port of check valve, adapts to different vehicles, and throttle degree is different, can effectively solve oil return abnormal sound problem.
Valve body 2 both ends external diameter is greater than external diameter in the middle part of valve body, is convenient to carry out fitted seal with sebific duct 1.
As shown in Figure 4 and Figure 5, turning to piping system, comprise the used oil pipe turning to piping system, used oil pipe is sebific duct 1, and check valve described above is located in sebific duct 1, and on sebific duct excircle, corresponding valve body position is fastening by card hoop 3.
Card hoop 3 is the electrodeless card hoop of single ear, and fixing reliable, it is convenient to assemble. During assembling, only need to valve body be filled in sebific duct, be undertaken fastening by card hoop.
The valve of various outer diameter can be selected, it is achieved the unidirectional dual-use function with throttling in valve body. During valve open, in sebific duct, liquid flows to from A to B, selects various outer diameter valve, it is achieved throttling in various degree; During valve closes, B is stoped to the liquid of reflux by valve, stops reverse liquid stream to the impact of system.
Above in conjunction with accompanying drawing to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the design of the present invention and the improvement of various unsubstantialities that technical scheme carries out; or without improving, the design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention.
