[0034] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0035] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0036] like Figure 1-9 As shown, one embodiment of the present invention provides a valve device 100, which can be used in the control system of a rail vehicle or other systems.

[0037] The valve device 100 includes a valve body 10, a valve core (not shown in the figure) disposed in the valve body 10, and a first control element 20 and a second control element 30 connected to the valve body 10. The first control element 20 and the second control element 30 are used to drive the valve core to move in different directions respectively when energized.

[0038] The valve body 10 is provided with multiple connecting ports. When the valve core moves to different positions within the valve body 10, the on / off relationship between the multiple connecting ports also changes. In this way, the valve device 100 can control the fluid flow path. Changing the on / off relationship between the various connecting ports of the valve device 100 by controlling the movement of the valve core is a prior art technique and will not be described in detail here.

[0039] It should be noted that in this embodiment, the valve core moves along the length of the valve body 10, and the valve core can move to two, three or even more positions along the length of the valve body 10.

[0040] The valve device 100 also includes a connector 40 connected to the valve body 10. The connector 40 is provided with a first terminal 41 electrically connected to the first control element 20 and a second terminal 42 electrically connected to the second control element 30. The first terminal 41 and the second terminal 42 are used to connect the electrical signals of the external device. When the external device energizes the first terminal 41, the first control element 20 is also energized. When the external device energizes the second terminal 42, the second control element 30 is also energized. That is, when the external device energizes the first terminal 41 or the second terminal 42, the corresponding control element is also energized, thereby controlling the valve core to move accordingly.

[0041] Using the above method, the first terminal 41 and the second terminal 42 on the connector 40 can be electrically connected to an external device respectively. The external device can centrally supply power to the two control components through the connector 40. The valve device 100 of this embodiment has low production cost and a compact structure with a small overall size. When the valve device 100 is applied to a braking system or other systems, the wiring of the system can be more centralized and simple.

[0042] In this embodiment, the first control element 20 and the second control element 30 are located on opposite sides of the valve body 10 along its length, and the connector 40 is located between the first control element 20 and the second control element 30 along the length of the valve body 10. Specifically, the connector 40 can be connected to the valve body 10 using fasteners such as screws.

[0043] The first control element 20 and the second control element 30 are respectively located on both sides of the valve body 10 along its length, and the connector 40 is located between the first control element 20 and the second control element 30, so that the valve device 100 can maintain structural symmetry. Furthermore, the connector 40 is located in the middle of the valve body 10, so it will not interfere with the operating elements for manually driving the valve core to move located on both sides of the valve body 10 along its length, thus avoiding the problem of inconvenience in operating the operating elements due to wiring or structural obstruction.

[0044] Connector 40 is located on one side of the valve body 10 in the height direction (e.g.) Figure 1 (as shown), or, the connector 40 is located on one side of the valve body 10 in the width direction (as shown). Figure 7-8 (As shown). The connector 40 can be flexibly repositioned according to actual wiring requirements, and the wires connected to the connector 40 can avoid bending as much as possible, so that the valve device 100 can be applied to different usage scenarios.

[0045] It should be noted that, in this article, the length direction of the valve body 10 is the direction in which the valve body 10 is located. Figure 1 The left and right directions of the valve body 10 in the shown state, and the height direction of the valve body 10 are when the valve body 10 is in the state shown. Figure 1 The vertical direction of the valve body 10 in the shown state, and the width direction of the valve body 10 when the valve body 10 is in the position shown. Figure 7 or Figure 8 The up and down directions in the shown state.

[0046] In this embodiment, the connector 40 includes a terminal block 43 connected to the valve body 10 and a connector 44 connected to the terminal block 43. A first terminal 41 and a second terminal 42 are connected to the terminal block 43. The connector 44 covers the first terminal 41 and the second terminal 42 and is used to enable an external device to electrically connect to the first terminal 41 and the second terminal 42 respectively. The terminal block 43 is connected to the valve body 10.

[0047] The connector 44 is connected to the terminal block 43 and covers the first terminal 41 and the second terminal 42. In this way, on the one hand, the first terminal 41 and the second terminal 42 can be effectively prevented from being exposed, and the first terminal 41 and the second terminal 42 can be protected from external impact, dust contamination, etc., thereby ensuring the durability of the first terminal 41 and the second terminal 42 and the stability of the electrical connection with the external device. On the other hand, the connector 44 can also make it more convenient to make electrical connections between the first terminal 41 and the second terminal 42 and the external device.

[0048] In this embodiment, both the first control element 20 and the second control element 30 are electromagnetic coils. Thus, when the first control element 20 and the second control element 30 are energized, they can generate magnetic force, and under the action of the magnetic force, the valve core can move.

[0049] The valve body 10 includes an intermediate part 11 located between the first control element 20 and the second control element 30, a connector 40 connected to the intermediate part 11, a first connecting line 21 extending from the first control element 20 to electrically connect to the first terminal 41, and a second connecting line 31 extending from the second control element 30 to electrically connect to the second terminal 42.

[0050] As explained above, the first control element 20 is an electromagnetic coil. Therefore, the first connecting line 21 is formed by extending the wire in the coil of the first control element 20 outward. The first connecting line 21 is electrically connected to the first terminal 41, so that when the first terminal 41 is energized, the first control element 20 can also be energized.

[0051] Similar to the first control element 20, the second connecting line 31 is formed by extending the wire in the coil of the second control element 30 outward. The second connecting line 31 is electrically connected to the second terminal 42, so that when the second terminal 42 is energized, the second control element 30 can also be energized.

[0052] In this embodiment, the first connecting line 21 and the second connecting line 31 are both disposed through the intermediate member 11. The intermediate member 11 protects the first connecting line 21 and the second connecting line 31, so that the electrical connection between the first control member 20 and the first terminal 41 and the electrical connection between the second control member 30 and the second terminal 42 are stable and reliable.

[0053] As can be imagined, in order to form a current loop when the first control element 20 and the second control element 30 are energized, two first connecting lines 21 and two connecting lines 31 are provided, two first terminals 41 are provided, and the two first terminals 41 are electrically connected to the two first connecting lines 21 respectively. Two second terminals 42 are also provided, and the two second terminals 42 are electrically connected to the two second connecting lines 31 respectively.

[0054] The intermediate component 11 has a cavity 12 formed inside for the first connecting line 21 and the second connecting line 31 to pass through. After the first connecting line 21 passes through the cavity 12, it is connected to the first terminal 41, and after the second connecting line 31 passes through the cavity 12, it is connected to the second terminal 42.

[0055] The chamber 12 includes a first port 121 near the intermediate member 11, which allows the first connecting line 21 and the second connecting line 31 to pass through the chamber 12. The valve device 100 also includes a first sealing gasket 51 disposed between the intermediate member 11 and the connector 40, the first sealing gasket 51 surrounding the first port 121. The first sealing gasket 51 prevents external impurities from entering the chamber 12 and the interior of the connector 40 through the gap between the connector 40 and the intermediate member 11, ensuring the reliability of the valve device 100 in use.

[0056] In this embodiment, the first port 121 is approximately cross-shaped. In other embodiments of this utility model, the terminal block 43 may be in other shapes, and the shape of the first port 121 may be changed accordingly based on the shape of the terminal block 43, as long as the first connecting line 21 and the second connecting line 31 can pass through the chamber 12.

[0057] Furthermore, the chamber 12 also includes a second port 122 near the first control member 20 and a third port (not shown in the figure) near the second control member 30. The first connecting line 21 enters the chamber 12 through the second port 122, and the second connecting line 31 enters the chamber 12 through the third port.

[0058] In this embodiment, both the second port 122 and the third port are circular. In other embodiments of this utility model, the second port 122 and the third port may also be of other shapes, which are not limited here.

[0059] The valve device 100 also includes a second sealing gasket 52 disposed between the first control member 20 and the intermediate member 11, a third sealing gasket 53 disposed between the second control member 30 and the intermediate member 11, a first connecting line 21 passing through the second sealing gasket 52, and a second connecting line 31 passing through the third sealing gasket 53.

[0060] The second sealing gasket 52 prevents external debris from entering the chamber 12 and the interior of the first control member 20 through the gap between the first control member 20 and the intermediate member 11. The third sealing gasket 53 prevents external debris from entering the chamber 12 and the interior of the second control member 30 through the gap between the second control member 30 and the intermediate member 11. In this way, the reliability of the valve device 100 is guaranteed.

[0061] The connector 40 may also include a fourth sealing gasket 54 disposed between the terminal block 43 and the connector 44. The fourth sealing gasket 54 can prevent external impurities from entering the terminal block 43 and the connector 44 through the gap between the terminal block 43 and the connector 44, thus ensuring the reliability of the valve device 100.

[0062] The valve body 10 includes a valve body 13, a first connecting post 14 and a second connecting post 15 connected to the valve body 13, a first connecting cap 16 and a second connecting cap 17 respectively connected to the first connecting post 14 and the second connecting post 15, a first control element 20 located between the valve body 13 and the first connecting cap 16, and the first connecting post 14 passes through the first control element 20, and a second control element 30 located between the valve body 13 and the second connecting cap 17, and the second connecting post 15 passes through the second control element 30.

[0063] After the first connecting post 14 passes through the first control member 20, the first control member 20 cannot move radially along the first connecting post 14. The first connecting cap 16 and the valve body 13 can restrict the first control member 20 from moving axially along the first connecting post 14. In this way, the first control member 20 can be reliably connected to the valve body 13. The intermediate member 11 can be connected to the valve body 13 by fasteners such as screws.

[0064] Similarly, after the second connecting post 15 passes through the second control member 30, the second control member 30 cannot move in the radial direction of the second connecting post 15. The second connecting cap 17 and the valve body 13 can restrict the second control member 30 from moving in the axial direction of the second connecting post 15. In this way, the second control member 30 can be reliably connected to the valve body 13.

[0065] The valve device 100 also includes a first operating member 60 and a second operating member 70 located on both sides of the valve body 10 along its length. The first operating member 60 and the second operating member 70 are used to control the valve core to move in different directions.

[0066] The operator can manually drive the valve core for precise movement using the first operating element 60 and the second operating element 70 to achieve manual reset. The first operating element 60 and the second operating element 70 are respectively located on both sides of the valve body 10 along its length, while the connector 40 is located in the middle of the valve body 10. This ensures that the operator has sufficient hand space when operating the first operating element 60 and the second operating element 70, making the valve device 100 more convenient to use.

[0067] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0068] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
