If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.
[0034] Refer to Figure 1As shown, an embodiment of the present application provides a water valve 100, which can prevent internal fluid from flowing into the actuator 120 in the internal leakage state, reducing damage to the actuator 120.
[0035] The water valve 100 includes a valve body 110, an actuator 120, and a water retaining ring 130. Among them, the valve body 110 and the actuator 120 are connected to control the opening and closing state of the valve body 110 under the drive of the actuator 120, and perform corresponding fluid delivery control. The water retaining ring 130 is arranged at the connection between the valve body 110 and the actuator 120 to lead out the leaked fluid and avoid damage to the actuator 120 caused by the fluid flowing into the actuator 120.
[0036] Exemplarily, the water valve 100 provided by the present application can be applied to an electric vehicle, and the fluid can be coolant.
[0037] Specifically, referring together to Figure 1 and Figure 3 As shown, the valve body 110 includes a mandrel 112 and a housing 111. One end of the mandrel 112 is installed inside the housing 111, and the other end passes through the housing 111 and extends outside the housing 111. A connection hole 121 is provided on one side of the actuator 120, and the actuator 120 is connected to the end of the mandrel 112 extending outside the housing 111 through the connection hole 121 to drive the mandrel 112 to control the opening and closing state of the valve body 110.
[0038] Furthermore, the housing 111 is attached to the outside of the mandrel 112 to reduce the outflow of internal coolant to a certain extent.
[0039] In some embodiments, a first seal 113 is provided between the housing 111 and the mandrel 112. A groove for installing the first seal 113 is correspondingly provided on the inner side of the housing 111. The first seal 113 is simultaneously attached to the wall surfaces of the housing 111 and the mandrel 112 to seal the gap between the housing 111 and the mandrel 112 and prevent the outflow of coolant.
[0040] Exemplarily, the first seal 113 can be an O-ring, a sealing strip, etc. to fill the gap between the housing 111 and the mandrel 112.
[0041] Continue to refer to Figure 2As shown, a through hole 131 is provided at the center of the water retaining ring 130, and the water retaining ring 130 is sleeved on the outer side of the mandrel 112 through the through hole 131. The water retaining ring 130 is arranged between the valve body 110 and the actuator 120, and the outer diameter of the water retaining ring 130 is larger than the outer diameter of the connection hole 121, so that the side of the water retaining ring 130 covers the connection hole 121. In this way, during the long-term operation of the water valve 100, the mandrel 112 rotates relative to the housing 111 and the first seal 113, and the first seal 113 wears. When the wear is excessive or there are other abnormal conditions, the coolant in the valve body 110 flows out through the gap between the housing 111 and the mandrel 112. Thus, through the setting of the water retaining ring 130, the water retaining ring 130 receives the coolant flowing down from the surface of the mandrel 112. At the same time, since the side of the water retaining ring 130 covers the connection hole 121, the received coolant is guided to the outside of the connection hole 121, thereby preventing the coolant from entering the actuator 120 through the connection hole 121 and preventing the actuator 120 from being damaged.
[0042] In some embodiments, the water retaining ring 130 is in interference fit with the mandrel 112, and the inner diameter of the through hole 131 is smaller than the outer diameter of the mandrel 112. Specifically, the water retaining ring 130 can be made of an elastic material such as rubber. Thus, through the interference fit, under the action of the elastic force, the water retaining ring 130 is installed on the outer side of the mandrel 112 and closely fits with the surface of the mandrel 112, realizing the seal between the water retaining ring 130 and the mandrel 112, better receiving the leaked coolant, and preventing the coolant from flowing out between the water retaining ring 130 and the mandrel 112. In other embodiments, the water retaining ring 130 and the mandrel 112 can also be fixedly connected by bonding or other means, and the seal between the water retaining ring 130 and the mandrel 112 can also be realized.
[0043] In some other embodiments, a sealing ring can be provided between the water retaining ring 130 and the mandrel 112 to achieve the same sealing effect between the water retaining ring 130 and the mandrel 112.
[0044] Refer to again Figure 2 As shown, in some embodiments, the water retaining ring 130 further includes a guiding surface 132 on the side close to the valve body 110, and the guiding surface 132 is inclined in the direction close to the actuator 120. Specifically, the water retaining ring 130 has a conical structure, that is, the height in the middle of the water retaining ring 130 is higher than the height of the side, and the height from the middle height of the water retaining ring 130 to the side height shows a gradually decreasing trend. Here, the height refers to the distance from the guiding surface 132 to the plane where the bottom of the water retaining ring 130 is located. Thus, after receiving the leaked coolant, the coolant flows out to the outside of the connection hole 121 along the inclined direction of the guiding surface 132, preventing the coolant from flowing into the connection hole 121.
[0045] Refer to together Figure 2 and Figure 4As shown, in some embodiments, a guiding fillet 133 is provided on one side of the guiding surface 132 close to the through hole 131. Specifically, by providing the guiding fillet 133, it is convenient to fabricate and form the water retaining ring 130. In addition, the aperture of the end of the through hole 131 is made larger than the aperture of the middle part of the through hole 131, so that in the interference fit between the water retaining ring 130 and the mandrel 112, it is convenient for the mandrel 112 to penetrate the water retaining ring 130 from one side of the guiding fillet 133, improving the assembly convenience of the water retaining ring 130 and the mandrel 112. Of course, in other embodiments, the guiding fillet 133 may not be provided on one side of the guiding surface 132 close to the through hole 131. For example, the aperture of the end of the through hole 131 is equal to the aperture of the middle part of the through hole 131, which can meet the installation of the water retaining ring 130 and the mandrel 112.
[0046] Furthermore, guiding fillets 133 may be similarly provided on the side of the through hole 131 facing away from the valve body 110 to achieve the same effects as in the above embodiments, and will not be repeated here.
[0047] In some embodiments, a plurality of drainage grooves 134 are formed in the guiding surface 132 and are distributed in the radial direction. The drainage grooves 134 are used to drain the fluid. Specifically, the plurality of drainage grooves 134 are arranged at intervals, so that after the water retaining ring 130 receives the leaked coolant, the coolant falls into the drainage grooves 134, and then flows out along different directions through the respective drainage grooves 134, effectively diverting the coolant to prevent the coolant from falling into the connection hole 121 of the actuator 120.
[0048] Exemplarily, the number of the drainage grooves 134 may be two, three, four, five, six, etc., and can be specifically selected according to actual requirements. The respective drainage grooves 134 are circumferentially distributed at equal intervals along the axis of the water retaining ring 130 to uniformly guide the coolant and prevent the coolant from seeping out through the drainage groove 134 with a large flow rate.
[0049] In some embodiments, each drainage groove 134 cuts off the guiding fillet 133, that is, the groove depth of each drainage groove 134 is greater than the thickness of the guiding fillet 133. Thus, during the flow of the coolant, it can be directly drained through the drainage groove 134 without remaining in the annular gap between the guiding fillet 133 and the mandrel 112.
[0050] Refer to Figure 3As shown, in some embodiments, the actuator 120 includes an end cap 122 and an output gear 123. The end cap 122 is provided with a connection hole 121. The core shaft 112 passes through the end cap 122 and is connected to the output gear 123. One end face of the output gear 123 close to the valve body 110 is exposed to the connection hole 121. Along the axial direction of the core shaft 112, the minimum distance between the water retaining ring 130 and the output gear 123 is a first preset distance H1, and the minimum distance between the water retaining ring 130 and the end cap 122 is a second preset distance H2. The first preset distance H1 is less than the second preset distance H2. Thus, after the water retaining ring 130 fails durably, even if the water retaining ring 130 falls off the core shaft 112, the water retaining ring 130 first contacts the output gear 123 and rotates with the output gear 123, remaining relatively stationary with the output gear 123, still meeting the water guiding function of the water retaining ring 130, and not affecting the operation of the water valve 100 at the same time.
[0051] Further, a second seal 124 is provided between the end cap 122 and the output gear 123. The second seal 124 can also be an O-ring, a sealing strip, etc., to fill the gap between the end cap 122 and the output gear 123 and prevent liquid leakage.
[0052] In other embodiments, the water retaining ring 130 and the end cap 122 are of an integrated structure, so that the water retaining ring 130 always covers the connection hole 121 of the actuator 120, without worrying about the problem of the water retaining ring 130 falling off the core shaft 112 after durable failure.
[0053] Continue to refer to Figure 5 As shown, in some embodiments, an abutting portion 135 is provided on one side of the water retaining ring 130 close to the actuator 120. The abutting portion 135 fits against the outer side of the core shaft 112 and corresponds to the end face of the output gear 123 along the axial direction of the core shaft 112. Specifically, the abutting portion 135 is arranged in the vertical direction, so that the first preset distance H1 is less than the second preset distance H2. A gap is left between the end cap 122 and the core shaft 112. Thus, after the water retaining ring 130 falls off the core shaft 112 due to durable failure, the abutting portion 135 first abuts against the end face of the output gear 123, making the water retaining ring 130 suspended compared with the end cap 122 and not directly contacting the end cap 122, ensuring the normal operation of the water valve 100.
[0054] The embodiment of the present application provides a vehicle, including the water valve 100 in any of the above embodiments.
[0055] This embodiment has the water valve 100 in any of the above embodiments. Therefore, it has all the beneficial effects of the water valve 100 in any of the above embodiments, which will not be elaborated here one by one.
[0056] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.
[0057] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
