[0021] The three-way fluid valve, particularly the three-way ball valve, realized according to the present utility model will be described below with reference to the accompanying drawings and by way of embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model for the purpose of the technical field concerned. It will be apparent, however, to one skilled in the art that the realization of the present utility model can not have some of these specific details. In addition, it should be understood that the present utility model is not limited to the specific embodiments introduced. On the contrary, it can be considered to realize the present utility model with any combination of the following features and elements, regardless of whether they relate to different embodiments.
[0022] Figure 1 A perspective view of one embodiment of a three-way fluid valve 100, particularly a three-way ball valve, such as a coolant flow control water valve, according to the present utility model is shown. The three-way fluid valve 100 comprises a valve housing 10, a spherical valve core 20 and a sealing member (not shown). The valve housing 10 defines a substantially spherical valve chamber 11 for receiving the spherical valve core 20, which has a bottom wall and a top wall as well as a side wall 12 extending between the top wall and the bottom wall, and three ports are opened in the side wall 12.
[0023] Figure 2 and Figure 3 A preferred embodiment of the spherical valve core 20 according to the present utility model is shown. As can be seen from the figure, the spherical valve core 20 is actually in the form of a truncated sphere, which defines a fluid passage 4, and the spherical valve core is rotatably arranged in the valve chamber 11. The spherical valve core 20 has a first end 22a, an opposite second end 22b, a circumferential side 21 extending between the first end and the second end, and a central rotation shaft 23 extending beyond the first end 22b, which defines a central rotation axis a of the spherical valve core.
[0024] Especially with reference to Figure 2The fluid passage 4 extends radially through the ball valve spool 20 from a first side of the peripheral side surface 21 to a second side of the peripheral side surface 21, which are opposite to each other, perpendicular to the central rotation axis a. In one preferred embodiment of the ball valve spool 20, the fluid passage 4 has a straight section 41 and a sector section 42 extending along the radial direction of the ball valve spool 20, wherein the arc of the sector section is 113.5°. In one specific embodiment, the fluid passage 4 extends between a first orifice 40 located at the first side and a second orifice 40' located at the second side, preferably, the first orifice is a waist-shaped hole and the second orifice is a circular hole. In the embodiment shown in the figure, the first orifice 40 is the starting portion of the sector section and the second orifice 40' is the starting portion of the straight section.
[0025] The seal is arranged between the inner side wall of the valve housing 10 and the peripheral side surface of the ball valve spool 20, and is provided with three openings corresponding to the three ports of the valve housing. Here, "corresponding" means that the layout and shape of the three openings in the seal are exactly the same as the layout and shape of the three ports in the valve housing. For example, the seal 30 can be in the form of a PTFE / EPDM composite gasket, which adopts a high-grade EPDM ternary ethylene-propylene rubber body that not only maintains good elastic properties at high and low temperatures, but also has very good chemical resistance and corrosion resistance.
[0026] In the utility model, through the cooperation of the structure of the fluid passage 4 in the ball valve spool 20 and the layout of the three ports in the valve housing 10, the three-way fluid valve 100 can regularly switch between multiple, for example, three different working modes (positions) when rotating the ball valve spool 20 in the valve chamber 11. In each of the working modes, at least two of the three ports are in fluid communication through the fluid passage, while the remaining port is blocked; and the three working modes include a proportional adjustment mode.
[0027] Again referring to Figure 1 The three ports in the valve housing 10 include a first port 1, a second port 2 and a third port 3 arranged circumferentially spaced apart along the side wall 12, wherein the first port 1 and the third port 3 are arranged 180° to each other, i.e. on the same straight line, and the second port is perpendicular to the first port and the third port. In this embodiment, the first port 1 and the third port 3 can be referred to as the two side ports, and the second port 2 is the middle port. And the first port, the second port and the third port are located in the same plane.
[0028] In a preferred embodiment, by providing the cooperation of the three ports of the ball valve spool and the valve housing, the first port 1 can be selected as the fluid inlet port, and the second port 2 and the third port 3 as the fluid outlet ports. Alternatively, the third port 3 can be selected as the fluid inlet port, and the first port and the second port as the fluid outlet ports. Thus, the scheme of liquid inlet through one of the two sides can be realized, thereby providing more schemes for the three-way fluid valve arrangement of the thermal management system.
[0029] Figure 4 A schematic diagram of the on-off state of each port when the three-way fluid valve 100 is in the first working mode is shown, which is a view of the three-way fluid valve along the plane in which the three ports are located. As can be seen from the figure, the fluid channel 4 is aligned with the first port 1 and the second port 2. In this first working mode, the rotation angle of the valve spool 20 is set to 0°, the first port 1 is in fluid communication with the second port 2 through the fluid channel 4, and the third port 3 is blocked. In this working mode, it is possible to inject fluid such as water from the first port 1 located on one side, and then flow out from the second port 2 located in the middle.
[0030] Figure 5 A schematic diagram of the on-off state of each port when the three-way fluid valve 100 is in the second working mode is shown, which is a view of the three-way fluid valve along the plane in which the three ports are located. Rotating the valve spool 20 in the first working mode by an angle a in the clockwise direction converts the three-way fluid valve to the second working mode, where 10° > a > 45°, and the second working mode is a proportional regulation mode. In this second working mode, the first port 1 is in fluid communication with the second port 2 and the third port 3 through the fluid channel 4. In this proportional regulation mode, as the number of degrees of rotation of the valve spool increases, the water inlet opening area of the first port remains unchanged, while the opening of the second port 2 becomes smaller and smaller, and the opening of the third port 3 becomes larger and larger. Specifically, when the valve spool 20 is rotated by 10° in the clockwise direction, the first port 1 is only in fluid communication with the second port 2, and not in fluid communication with the third port 3, and as the number of degrees of rotation of the valve spool increases, the flow of liquid from the first port 1 to the second port 2 becomes less and less, while the flow of liquid from the first port 1 to the third port 3 becomes more and more. In this working mode, it is possible to inject fluid such as water from the first port 1 located on one side, and then flow out from the second port 2 located in the middle and the third port 3 located on the other side, and proportional regulation can be achieved.
[0031] Figure 6 A schematic diagram of the on-off state of each port when the three-way fluid valve 100 is in the third working mode is shown, which is a view of the three-way fluid valve along the plane in which the three ports are located. By rotating the valve spool 20 in the second working mode by an angle a in the clockwise direction, the three-way fluid valve is converted to the third working mode, where 45° > a > 90°, and the third working mode is a proportional regulation mode. In this third working mode, the first port 1 is in fluid communication with the second port 2 and the third port 3 through the fluid channel 4. In this proportional regulation mode, as the number of degrees of rotation of the valve spool increases, the water inlet opening area of the first port remains unchanged, while the opening of the second port 2 becomes smaller and smaller, and the opening of the third port 3 becomes larger and larger. Specifically, when the valve spool 20 is rotated by 45° in the clockwise direction, the first port 1 is only in fluid communication with the second port 2, and not in fluid communication with the third port 3, and as the number of degrees of rotation of the valve spool increases, the flow of liquid from the first port 1 to the second port 2 becomes less and less, while the flow of liquid from the first port 1 to the third port 3 becomes more and more. In this working mode, it is possible to inject fluid such as water from the first port 1 located on one side, and then flow out from the second port 2 located in the middle and the third port 3 located on the other side, and proportional regulation can be achieved. Figure 1Rotation of the ball valve spool 20 shown in the first mode of operation by 55° in the clockwise direction enables the three-way fluid valve to be switched to a third mode of operation in which the first port 1 is in fluid communication with the third port 3 via the fluid passage 4, while the second port 2 is blocked. In this mode of operation, it is possible to inject fluid, for example water, from the first port 1 on one side and then to discharge it from the first port 2 on the other side.
