For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.

Fig. 1 shows a connection of a water valve to a manifold 2, with reference to fig. 1, the water valve and the manifold 2 being secured by a threaded connection. Specifically, with continued reference to FIG. 1, the water valve has threaded holes 13 circumferentially spaced (as indicated by the R direction in FIG. 1). In order to prevent leakage of coolant from between the water valve and the manifold 2, an end face seal 15 is developed, between the first connection end 10 (as shown in fig. 3) and the second connection end 20 (as shown in fig. 2). Furthermore, to ensure the fixing strength of the assembly, inserts 14 are provided on the water valve housing 10 and the manifold 2 at positions corresponding to the screw holes 13, respectively, and the inserts 14 on the water valve housing 10 and the manifold 2 are integrally injection-molded, for example.

In the above prior art embodiment, it is necessary to fix the water valve to the manifold 2 by means of screws 16 and to add a seal 15 between the first connection end 10 and the second connection end 20. The number of parts is large, the assembly process is more, and the end face sealing effect is poor. Therefore, the connection fixing effect of the water valve 1 and the manifold 2 is poor.

Based on the above problems, referring to fig. 2 in combination with fig. 3, the present utility model provides a manifold 2 comprising: the water valve comprises a water valve shell 1 and a manifold 2, wherein a first connecting end 10 is arranged at the bottom of the water valve shell 1, and a second connecting end 20 is arranged on the outer surface of the manifold 2. Wherein, the first connecting end 10 is provided with at least one opening 11, and the second connecting end 20 is provided with at least one liquid port 21 corresponding to the at least one opening 11. The first connection end 10 and the second connection end 20 are connected to each other to fixedly connect the water valve housing 1 and the manifold 2, so that each opening 11 and the corresponding liquid port 21 are connected, and each opening 11 and the corresponding liquid port 21 are communicated with each other.

The at least one opening 11 is not communicated with each other, and the at least one liquid port 21 corresponding to the at least one opening 11 is not communicated with each other. That is, each of the openings 11 is hermetically connected to the corresponding liquid port 21, and the openings 11 are independent of each other, so that the independent openings 11 and the corresponding liquid port 21 form mutually independent cooling liquid passages together for the flow of cooling liquid.

In some possible embodiments, the first connection end 10 and the second connection end 20 are configured to be fixedly connected in a welded manner. Illustratively, referring to fig. 2 in combination with fig. 3, the first and second connection ends 10, 20 are each planar, such that a welding process is used to form a weld between the first and second connection ends 10, 20. Specifically, a welding point (not shown) between the first connection end 10 and the second connection end 20 is provided on the end surface of the first connection end 10 along the circumferential direction of at least one liquid port 21, the welding point is provided around the peripheral edge of the opening 11, and the opening 11 is fixedly connected to the corresponding liquid port 21. Furthermore, the weld formed by the welding spots around the peripheral edges of the openings 11 can act as a seal to sealingly connect at least one opening 11 with the corresponding liquid port 21. The number of parts is reduced, the development of end face sealing elements is omitted, and the production cost is saved.

In some possible embodiments, the first connection end 10 and the second connection end 20 are configured to be fixedly connected in an integrally formed manner. Specifically, the parts of the water valve housing 1 are independently stripped and integrated on the manifold 2, namely, the water valve housing 1 and the manifold 2 are designed into an integral injection molding piece, and the first connecting end 10 and the second connecting end 20 are fixedly connected through an injection molding process. The integration degree of the water valve shell 1 and the manifold 2 is improved, the number of parts is optimized, the number of fixing screws is reduced, the development of an end face sealing piece 15 (shown in fig. 1) is saved, the development of a mould of the water valve shell 1 is saved, and the assembly process of the water valve is optimized.

In some possible embodiments, referring to fig. 2 in combination with fig. 3, at least one opening 11 comprises a side opening and a central opening 111, and the corresponding at least one fluid port 21 comprises a side fluid port 211 and a central fluid port 212. Illustratively, referring to FIG. 2, at least one fluid port 21 includes four side fluid ports 211 and a central fluid port 212, and referring to FIG. 3, at least one opening 11 includes four side openings (provided in the bottom of the arcuate open cavity 16 in FIG. 3) and a central opening 111. The four side liquid ports 211 are arranged at intervals along the circumferential direction of the central opening 111 (as shown in the R direction in fig. 2), the side liquid ports 211 and the central opening 111 are all arranged on the outer surface of the manifold 2, the side openings are arranged opposite to the side liquid ports 211, the central opening 111 is arranged opposite to the central liquid port 212, and the side openings and the central opening 111 are all arranged at the bottom of the water valve shell 1. In addition, the areas of the at least one opening 11 and the corresponding at least one liquid port 21 are equal, which is beneficial for the circulation of the cooling liquid between the water valve housing 1 and the manifold 2. Furthermore, referring to fig. 3, the water valve housing 1 further comprises a cavity 12 therein, and at least one opening 11 communicates with the cavity 12, respectively, i.e. four side openings and one central opening 111 communicate with each other in the water valve housing 1 through the cavity 12.

Illustratively, with continued reference to fig. 2 and 3, the central liquid port 212 and the central opening 111 are both circular in open cross-section. The cross-sectional shapes of the center liquid port 212 and the center opening 111 are not particularly limited, and the present utility model may be of a square shape, a polygonal shape, or the like, which satisfies the need for the coolant to flow between the water valve housing 1 and the manifold 2.

While the utility model has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing is a further detailed description of the utility model with reference to specific embodiments, and it is not intended to limit the practice of the utility model to those descriptions. Various changes in form and detail may be made therein by those skilled in the art, including a few simple inferences or alternatives, without departing from the spirit and scope of the present utility model.
