In the case where valve body two ends valve port does not enter liquid, in free state, when valve body connects hydraulic fluid, valve element can not be steady
At fixing limit, the situation of spacing place hydraulic fluid leakage is sometimes resulted in.
The content of the invention
The problems referred to above in the presence of in order to solve prior art, the present invention provides a kind of stable state No leakage steel-ball type shuttle
Valve.
The present invention provide technical scheme be：A kind of stable state No leakage steel ball-type shuttle valve, including its two ends and top difference
The valve body of valve port is provided with, is provided with coaxial with valve body two ends valve port for connecting the valve body two ends and top in the valve body
The valve road of portion's valve port, in the valve road valve element is provided with；It is theed improvement is that：The valve body two ends are coaxially installed with hollow stifled
Head, is coaxially installed with the hollow magnet for connecting the plug in the valve road；The valve element is steel ball.
Preferably, the plug includes integrally formed passage and hollow limiting stand, and the passage is co-axially located at described
In valve body, the limiting stand is co-axially located at outside the valve body.
Further, it is provided between the passage and the valve body and the concentric sealing ring of valve body two ends valve port.
Preferably, the valve body is to be provided be located at respectively the valve along its axis direction in hollow circular cylinder, the valve road
Spacing section of body top valve port both sides, described spacing section of aperture is less than the diameter of the valve element so that the valve element is described
Move in valve road between spacing section of body top valve port both sides.
Further, aperture of the aperture at the valve road two ends more than described spacing section.
Further, one end of magnet is connected with described spacing section, and the other end is connected with plug.
Further, the magnet is hollow circular cylinder, and the hollow face of the magnet is the face of cylinder, and the aperture of the magnet is omited
Aperture less than described spacing section.
Preferably, aperture of the aperture of the plug more than the magnet.
Further, the described spacing section song being adapted with the valve element in size and shape with the contact surface of the valve element
Face.
Further, when the valve element is along the side shifting of valve road axis one, by the spacing of the body top valve port side
During section closing, the plug of the valve road axis opposite side is connected with the valve port of the body top.
Compared with immediate technical scheme, the present invention has following marked improvement：
1) simple structure of the shuttle valve that the present invention is provided, good stability, low cost of manufacture, reliability is high；
2) magnet is connected with spacing section, when valve element is when Jie Jin spacing section, limit can be stably fixed under the attraction of magnet
At the limited mouth of position section, the leakage of hydraulic fluid is effectively prevent；
3) spacing section is arranged between magnet and valve element, it is ensured that valve element while by attraction, not directly and magnet
Contact, it is therefore prevented that shuttle valve smooth can not open spacing section of through hole when liquid is entered because pressure is too small, improve the reliability of shuttle valve
Property；
4) when valve element is fixed on spacing section, the spacing section of song being adapted with valve element in shapes and sizes with the contact surface of valve element
Face, can increase the seal of valve element and valve port, effectively prevent hydraulic fluid from leaking.

Specific embodiment
For a better understanding of the present invention, present disclosure is done further with reference to Figure of description and example
Explanation.
As shown in Figure 1：The shuttle valve that the present invention is provided includes valve body, valve element, magnet and plug, and valve element is steel ball, in valve body
It is provided with valve road, valve road and limited location section is set, spacing section is located at respectively valve port B both sides, spacing at two for limiting valve element
Move between section, magnet and plug are installed in valve road axis direction both sides, the plug is hollow, root assembling O-ring seals form close
Envelope.
Magnet is hollow form, facilitates liquid to flow, and aperture is slightly less than spacing section of aperture, when steel ball is near spacing section of valve
Kong Shi, magnet attracts steel ball so as to stable at valve opening, closes oil duct.Spacing section is curved surface with the contact surface of valve element, can be increased
Big spacing section with the contact area of valve element, seal of the reinforcement valve element to valve opening.Valve road side-wall hole, goes out as hydraulic fluid
Mouthful.
The specific work process of shuttle valve is as follows：
1) valve port A and valve port B is connected
Hydraulic fluid enters valve port A by plug, and then enters valve body, promotes the steel ball in valve body valve road to transport to the right
It is dynamic, valve port B is opened, valve port A and valve port B is connected, hydraulic fluid continues to press on steel ball and moves right, until the limit of valve road right-hand member
Position section, makes the through hole end contact of the sphere of steel ball and spacing section of right side, forms sealing, it is ensured that at valve port A, valve port B and valve port C
In sealing.The attraction that now steel ball passes through magnet, is firmly secured at spacing section of valve opening, it is ensured that no matter valve port A is
No fuel feeding, steel ball is contacted all the time with the through hole end face of valve road, and valve port C is in all the time closed state.
2) valve port C and valve port B is connected
Hydraulic fluid enters valve port C by plug, and then enters valve body, when hydraulic fluid is more than magnet to the active force of steel ball
Attraction when, hydraulic fluid promotes steel ball in the valve body valve road to left movement, opens valve port B, makes valve port C and valve port B
Connect, hydraulic fluid continues to press on steel ball to left movement, until sphere and the end contact in spacing section of left side of steel ball, is formed close
Envelope, it is ensured that in sealing between valve port C, valve port B and valve port A.The attraction that now steel ball passes through magnet, is firmly secured to limit
At the valve opening of position section, it is ensured that no matter valve port C whether fuel feeding, steel ball is contacted all the time with the through hole end face of valve road, and valve port A locates all the time
In closed state.
Embodiments of the invention are these are only, the present invention is not limited to, it is all in the spirit and principles in the present invention
Within, any modification, equivalent substitution and improvements done etc. are being applied within pending scope of the presently claimed invention.
