[0023] Reference Figures 1 to 5 According to a preferred embodiment of the present application, the disc type multi-way valve will be described in detail below. The disc type multi-way valve comprises a plurality of valve mechanisms 10 and a switching mechanism 20. All the valve mechanisms 10 are divided into two groups, and one group of the valve mechanisms 10 is arranged at each end of the switching mechanism 20. Each group is provided with one valve mechanism 10 connected with the switching mechanism 20 by a fastener, for example, the fastener is implemented as a bolt.

[0024] Specifically, each valve mechanism 10 comprises a valve body 11, a valve core 12 and a control moving member 13.

[0025] The valve body 11 forms a moving passage 1101. The valve body 11 also forms two oil inlet and outlet ports 1102, a first oil inlet passage 1103 and a first oil return passage 1104. The oil inlet and outlet ports 1102 are connected to an actuator through pipes, and the oil inlet and outlet ports 1102, the first oil inlet passage 1103 and the first oil return passage 1104 are all connected to the moving passage 1101. The valve body 11 also forms at least one first connecting port 1105 connected to the first oil inlet passage 1103 and at least one second connecting port 1106 connected to the first oil return passage 1104. The two oil inlet and outlet ports 1102 formed by each valve mechanism 10 in the same group are located on the same side, and the two oil inlet and outlet ports 1102 formed by each valve mechanism 10 in different groups are located on opposite sides.

[0026] The valve core 12 is slidably installed in the moving passage 1101. When the valve core 12 is in a preset position, the two oil inlet and outlet ports 1102 are each blocked by the valve core 12 through a flow path between the moving passage 1101 and the first oil inlet passage 1103. When the valve core 12 moves in the moving passage 1101 and deviates from the preset position, one of the oil inlet and outlet ports 1102 is connected to the first oil inlet passage 1103 through a gap between the valve core 12 and the inner wall of the moving passage 1101. Oil can enter the valve body 11 through the first oil inlet passage 1103 via the first connecting port 1105, and oil in the valve body 11 is discharged from the second connecting port 1106 via the first oil return passage 1104.

[0027] The valve core 12 is drivingly connected to the moving control member 13, and the moving control member 13 drives the valve core 12 to move axially along the moving passage 1101 so that the valve core 12 deviates from or moves to a preset position along the moving passage 1101.

[0028] The conversion mechanism 20 forms a second oil inlet passage 2001, a second oil return passage 2002, two first butt passages 2003 and two second butt passages 2004.

The two first butt passages 2003 are both connected to the second oil inlet passage 2001, and the two second butt passages 2004 are both connected to the second oil return passage 2002.

[0029] In one embodiment, the valve body 11 forms a first connection port 1105 and a second connection port 1106. Each group is provided with one valve mechanism 10. Both valve mechanisms 10 keep the first connection port 1105 and the second connection port 1106 formed by themselves respectively aligned with the first interface channel 2003 and the second interface channel 2004 formed by the conversion mechanism 20.

[0030] In another embodiment, the valve body 11 forms two first connection ports 1105 and two second connection ports 1106. The inner wall of the first connection port 1105 and the second connection port 1106 formed by the valve body 11 is provided with internal threads, and two plugs can be threadedly mounted sealingly in the first connection port 1105 and the second connection port 1106. In this way, the user can adjust the number of valve mechanisms 10 in each group according to the use requirements. The first connection port 1105 and the second connection port 1106 formed by the valve body 11 of the valve mechanism 10 at the end of each group can be plugged by the plug.

[0031] In one example, each group is provided with one valve mechanism 10. Both valve mechanisms 10 keep the first connection port 1105 and the second connection port 1106 formed by themselves respectively aligned with the first interface channel 2003 and the second interface channel 2004 formed by the conversion mechanism 20; the other first connection port 1105 and the other second connection port 1106 formed by the valve mechanism 10 are both threadedly mounted with plugs.

[0032] In another example, at least one group is provided with multiple valve mechanisms 10. The first connection port 1105 and the second connection port 1106 formed by the valve mechanism 10 adjacent to the conversion mechanism 20 are respectively aligned with the first interface channel 2003 and the second interface channel 2004 formed by the conversion mechanism 20. The first connection port 1105 and the second connection port 1106 formed by one valve mechanism 10 are respectively aligned with the first connection port 1105 and the second connection port 1106 formed by another valve mechanism 10 in the same group in a stacked connection manner. In this way, when the valve core 12 provided by any valve mechanism 10 is driven by the control moving member 13 to deviate from the preset position along the axial direction of the moving channel 1101, the oil enters the corresponding inlet and outlet port 1102 through the first interface channel 2003 and the first oil inlet channel 1103 from the second oil inlet channel 2001.

[0033] Preferably, the valve core 12 comprises a cylinder 121, two flow blocking portions 122 and an opening and closing portion 123. The cylinder 121 is partially expanded in radial direction to form the two spaced apart flow blocking portions 122 and the opening and closing portion 123, and the opening and closing portion 123 is located between the two flow blocking portions 122. The outer periphery of the opening and closing portion 123 forms a flow control wall 1231. The valve body 11 further forms two partition walls 111. The flow control wall 1231 is arranged to be disengaged from or sealingly abutted against the corresponding partition wall 111 with the movement of the valve core 12.

[0034] It is worth mentioning that the outer periphery of each flow blocking portion 122 forms a sealing wall 1221. The sealing wall 1221 formed by the flow blocking portion 122 keeps abutted against the inner wall of the movement passage 1101 formed by the valve body 11 to prevent oil leakage from the connection between the movement member 13 and the valve body 11.

[0035] Preferably, the flow blocking portions 122 and the opening and closing portion 123 are integrally formed with the cylinder 121.

The movement leading assembly 1311 is arranged to be energized, and the movement belt member 1312 is arranged to move towards or away from the valve core 12 when the movement leading assembly 1311 is energized.

[0037] In this way, when the movement leading assembly 1311 arranged by each movement component 131 is de-energized, the valve core 12 is located at a predetermined position of the movement passage 1101, and the valve core 12 blocks the flow path between the two inlet and outlet ports 1102 and the first oil inlet passage 1103. When the movement leading assembly 1311 arranged by any movement component 131 is energized, the movement belt member 1312 assembled with the energized movement leading assembly 1311 moves along the axial direction of the movement passage 1101, and the movement belt member 1312 drives the valve core 12 to move in the same direction to make one inlet and outlet port 1102 communicate with the first oil inlet passage 1103.

[0038] In an embodiment, the movement leading assembly 1311 is implemented by a magnet and a coil, etc., and the movement belt member 1312 is implemented by a magnetic material.

[0039] Preferably, the moving control component 131 further comprises an elastic reset member 1313 connected to the valve core 12 in a way that it can be elastically deformed, and when the valve core 12 is moved along the axial direction of the moving channel 1101 driven by the moving belt 1312, the elastic reset member 1313 is elastically deformed and has a tendency to push the valve core 12 to reset, so that when the moving control component 131 is powered off, the valve core 12 is reset under the elastic force of the elastic reset member 1313.

[0040] In an example, the elastic reset member 1313 is implemented as a spring.

[0041] It is worth mentioning that the conversion mechanism 20 further forms a plug-in channel 2005 in communication with the second oil inlet channel 2001, and a pressure detector part is plugged into the plug-in channel 2005, so that the pressure detector detects the oil pressure in the second oil inlet channel 2001.

[0042] It should be understood by those skilled in the art that the above description and the embodiments of the utility model shown in the drawings are only examples and do not limit the utility model. The advantages of the utility model have been fully and effectively realized. The function and structural principle of the utility model have been shown and explained in the embodiments, and the embodiments of the utility model can be any deformation or modification without departing from the principle.
