The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. Furthermore, the technical features mentioned in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 to 4, the multi-way valve 100 of the present invention includes a valve body 1, a double-layer valve core 2 disposed in the valve body 1, and a cover 3, a first sealing member 4 and a second sealing member 5 disposed in the valve body 1 for limiting the double-layer valve core 2.

The first sealing element 4 is arranged between the cover 3 and the double-layer valve core 2, and the second sealing element 5 is arranged between the valve body 1 and the double-layer valve core 2.

The double-layer spool 2 includes a first spool 21 and a second spool 22 having opposite openings. The first valve core 21 and the second valve core 22 are respectively provided therein with a plurality of flow passages 23 and partition plates 24 for partitioning the flow passages 23.

Fluid is simultaneously introduced into the first valve spool 21 and the second valve spool 22, so that the pressures on two sides of the double-layer valve spool 2 are equivalent, and abrasion or overturning caused by pressure on one side is avoided. The first spool 21 and the second spool 22 are coaxially disposed and are rotatable relative to each other.

The first valve spool 21 is provided with a first stopper 211 and a second stopper 212 protruding toward the second valve spool 22. The first stopper 211 and the second stopper 212 are radially arranged at intervals, the first stopper 211 and the second stopper 212 are both concentric and fan-shaped with the double-layer valve core 2, symmetry axes of the first stopper 211 and the second stopper 212 coincide, and the first stopper 211 is close to the axis of the double-layer valve core 2 relative to the second stopper 212.

The second spool 22 has a third stopper 221 and a fourth stopper 222 protruding toward the first spool 21, and a first slide groove 223 and a second slide groove 224 recessed inward from the surface. The third stopper 221 and the fourth stopper 222 are fixedly disposed in the first slide groove 223 and the second slide groove 224.

The third stopper 221 and the fourth stopper 222 are radially arranged at intervals, the third stopper 221 and the fourth stopper 222 are both in a sector shape concentric with the double-layer valve core 2, symmetry axes of the third stopper 221 and the fourth stopper 222 coincide, and the third stopper 221 is close to an axis of the double-layer valve core 2 relative to the fourth stopper 222.

The first stopper 211 and the second stopper 212 are respectively received in the first slide groove 223 and the second slide groove 224. When the first spool 21 rotates relative to the second spool 22, the first stopper 211 and the second stopper 212 slide in the first slide groove 223 and the second slide groove 224, respectively.

The double-layer valve core 2 has a first state in which the first valve core 21 rotates relative to the second valve core 22, and a second state in which the first stopper 211 and the second stopper 212 respectively abut against the third stopper 221 and the fourth stopper 222 to restrict the first valve core 21 and the second valve core 22 from rotating relative to each other.

In some embodiments, the first spool 21 and the second spool 22 are provided with a filling part in the middle, and the flow passage 23 is provided around the filling part.

And the axial projection of the first stopper 211, the third stopper 221 and the first sliding groove 223 is located in the filling part.

The thickness of the first stopper in the axial direction is greater than that of the second stopper 212, and the first stopper 211 and the third stopper 221 are located in the projection of the filling part, so that the thickness is set to be thicker, and the area of a contact surface can be increased to resist greater torque. The first stopper 211 and the second stopper 212 have a thickness of about 4 mm. The axial direction here refers to the axial direction of the double-layer valve element 2.

The second stopper 212 has a thickness gradually decreasing from the axial direction toward the direction away from the axis. The height of the end, close to the axis, of the second stopper 212 is 2mm, and the height of the end, far away from the axis, of the second stopper is 0.8mm. Since the second stopper 212 and the fourth stopper 222 are located in the projection of the flow channel 23, the thickness is set to be thinner, and the volume of the flow channel 23 can be increased as much as possible, so that more fluid can pass through the same unit time.

At the same time, the resistance of the second stop 212 and the fourth stop 222 is increased, and the torque which can be resisted is also increased.

The utility model discloses a multi-way valve 100 and double-deck case 2 through setting up first dog 211 and third dog 221, second dog 212 and the fourth dog 222 that supports each other, thereby can increase backstop area of contact, make double-deck case 2 can bear bigger moment of torsion, can prevent to reveal, and then improves multi-way valve 100's life-span and stability.
