Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a multi-way valve, which includes a housing 10, a valve core 20, and a gasket. A containing cavity is arranged in the shell 10, a plurality of runner ports 11 are arranged on the side wall of the shell 10, the runner ports 11 are communicated with the containing cavity, the plurality of runner ports 11 are arranged in two rows along the circumferential direction of the shell 10, and the arrangement direction of each row of runner ports 11 is parallel to the axis of the shell 10; the valve core 20 is rotatably arranged in the accommodating cavity; the sealing gasket is provided with a plurality of through holes, the through holes are arranged in one-to-one correspondence with the flow passage ports 11, and the sealing gasket is arranged in the accommodating cavity and is positioned between the valve core 20 and the flow passage ports 11.

The side wall of the casing 10 needs to be connected with a runner plate, the runner plate is provided with a plurality of runners, the runners are arranged in one-to-one correspondence with the runner ports 11, one end of each runner is connected with the runner port, and the other end of each runner needs to be arranged on two sides of the runner plate so as to be connected with other parts. If the flow channel port 11 is set to be more than two rows, the flow channel connected to the flow channel port provided in the middle portion will block the flow channel ports located on both sides, which results in the circumferential dimension of the flow channel port being smaller than that of the flow channel, resulting in a large flow resistance of the fluid. And set up runner mouth 11 into two lines, can make things convenient for the runner on the overall arrangement runner board, reduce the design degree of difficulty and the processing degree of difficulty of runner board.

As shown in fig. 2 and 4, if the diameters of the valve cores are the same, the widths of the flow port openings 11 in the circumferential direction are all L, the distances from the flow port openings 11 to the axis of the valve core 20 are all L1, the distances from the adjacent flow port openings 11 in the circumferential direction are all L2, the circumferential angle of the portion of the valve core corresponding to the flow port opening 11 when the flow port openings 11 are arranged in two rows is a, and the circumferential angle of the portion of the valve core corresponding to the flow port opening 11 when the flow port openings 11 are arranged more than two rows is b, then a < b. When the flow channel ports 11 are arranged in two rows, the number of flow patterns that can be provided on the valve element is 360 °/a; when the flow channel port 11 is set to be more than two lines, the number of flow modes which can be set on the valve core is 360 DEG/b; therefore, the flow passage ports 11 are provided in two rows, and the flow pattern of the multi-way valve can be increased.

As shown in fig. 3 and 4, if the width of each of the flow channel openings 11 in the circumferential direction is L, the distance between adjacent flow channel openings 11 in the circumferential direction is L2, and when the flow channel openings 11 are arranged in two rows or more, the circumferential angle of the portion of the valve core corresponding to the flow channel opening 11 is b. The flow port 11 is provided in two rows, and the diameter of the valve element can be made small, so that the overall structural size of the multi-way valve can be reduced.

Use the technical scheme of the utility model, be provided with two lines of runner mouths 11 on the casing 10, runner mouth 11 sets up with the through-hole one-to-one on the sealed pad. By the arrangement, the circumferential size of the runner port is the same as that of the runner plate, so that the flow resistance of the fluid is smaller; by adopting the structure, the layout difficulty and the processing difficulty of the runner plate can be reduced; in the case of the same size of the flow ports 11, the diameter of the valve element 20 in this application is smaller than the diameter of the valve element 20 in the prior art, so that the overall size of the multi-way valve can be reduced. By adopting the technical scheme, the multi-way valve has a simple structure and can better improve various performances of the multi-way valve.

Specifically, the number of the level crossings 11 per row is less than or equal to 6. If the quantity of every row of runner mouth 11 is greater than 6, then the whole length of casing 10 is great to lead to the casing 10 bulky and the space that occupies great, and lead to the structural strength of casing 10 lower, consequently, set up to every row of runner mouth 11 quantity less than or equal to 6, can make the casing 10 the volume less and can make the structural strength of casing 10 great, thereby make the holistic less and structural strength of multi-way valve great.

Specifically, the width dimension of the flow channel port 11 in the circumferential direction is L, and the range of L is 10mm to 12 mm. If L is less than 10mm, the cross-sectional area of the runner port 11 is small, resulting in a slow fluid flow rate; if L is greater than 12mm, the cross-sectional area of the flow passage port 11 is too large, which results in a large structural size of the housing 10, and the circumferential angle of the valve core and the corresponding part of the flow passage port 11 is large, thus resulting in a small flow pattern of the valve core and the flow passage port 11; therefore, the range of L is set to 10mm to 12mm, the fluid flow rate can be made fast, the volume of the housing 10 can be made small, and the flow pattern in which the valve element and the flow port 11 are fitted can be made small. In particular, L may be 10mm, 11mm or 12 mm.

Specifically, in each row of the runner ports 11, the distance between two adjacent runner ports 11 is a, and the range of a is 6mm to 10 mm. If A is smaller than 6mm, the processing difficulty of the shell 10 is larger, and the processing difficulty of the runner plate matched with the runner port 11 is larger; if a is greater than 10mm, the length of the housing 10 is greater, resulting in a larger volume and a lower structural strength of the housing 10; therefore, setting a to 6mm to 10mm can make the processing difficulty of the housing 10 small, can make the volume of the housing 10 small, and can make the structural strength of the housing 10 large. In particular, A may be 6mm, 8mm or 10 mm.

Specifically, the distance between two adjacent rows of runner ports 11 is L2, and the range of L2 is 6mm to 10 mm. If L2 is smaller than 6mm, the difficulty in processing the housing 10 is high, and the difficulty in processing the runner plate matched with the runner port 11 is high; if L2 is greater than 10mm, the structural size of the housing 10 is large, which results in a large volume of the housing 10, and thus the circumferential angle of the valve core corresponding to the flow passage opening 11 is also large, which results in a small flow pattern of the valve core matching the flow passage opening 11; therefore, setting L2 to 6mm to 10mm makes it possible to make the housing 10 less difficult to process, the flow path plate less difficult to process, the housing 10 smaller in size, and the valve element more frequently fit to the flow path port 11. In particular, L2 may be 6mm, 8mm or 10 mm.

In the present embodiment, the valve core 20 has a cylindrical structure, and an end portion of the flow passage opening 11 close to one end of the valve core 20 is a cambered surface and is adapted to a circumferential surface of the valve core 20. The flow mode of the multi-way valve is switched by rotating the valve spool 20, and thus the valve spool 20 is provided in a cylindrical structure. The valve core 20 is internally provided with a circulation cavity, and fluid enters the circulation cavity from one part of the flow port 11 and then flows out from the other part of the flow port 11, so that by adopting the structure, the flow port 11 can be better connected with the circulation cavity of the valve core 20, the fluid can flow in the valve core 20 and the flow port 11 more stably, and the flow resistance is smaller.

Specifically, an end surface of the flow passage port 11 at an end away from the valve element 20 is a plane. So set up, can make things convenient for the runner plate to be connected with casing 10, and can make things convenient for the circulation passageway of runner plate to be connected with runner port 11.

In the present embodiment, the two-row port opening 11 is provided on the housing 10 symmetrically with respect to the axis of the valve element 20. Thus, the flow passage port 11 can be conveniently arranged corresponding to the flow cavity of the valve core 20, and the multi-way valve can be conveniently designed and assembled.
