It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
It is also noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a good or system that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such good or system. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a commodity or system that includes the element.
Because at present, a plurality of components are required to be adopted for controlling a plurality of water channels, and the control is realized through a plurality of electromagnetic valves, the cost and the space are greatly increased.
As shown in fig. 1-5, the present invention discloses a rotary multi-way valve, comprising: a housing 1, a valve core 2 and a drive assembly 3. The shell 1 adopts a long cylindrical structure; the valve core 2 is rotatably arranged in the shell 1 along the axial direction of the long cylinder of the shell, and adopts a columnar structure; the driving assembly 3 is arranged on one side of the valve core and drives the valve core 2 to rotate in the shell 1. The valve is simple in structure and convenient to process, can be used for combining a plurality of water paths and is switched and controlled by one valve, the complicated water paths can be simplified, and the cost of the whole water path is reduced.
To realize the matching communication between the shell 1 and the valve core 2. A housing inlet 101 is provided on an upper peripheral surface of the housing 1, and a plurality of housing outlets are provided on a lower peripheral surface (the upper peripheral surface and the lower peripheral surface are arranged in opposition to each other, and the relative relationship between the housing inlet 101 and the housing outlets is merely for convenience of explanation).
Correspondingly, a plurality of valve core liquid inlets which are communicated with the shell liquid inlet 101 are formed on the peripheral surface of the valve core 2; and a plurality of valve core liquid outlets communicated with the plurality of shell liquid outlets are formed. The multiple valve core liquid inlets and the multiple valve core liquid outlets are in one-to-one correspondence, a flow channel is formed between each valve core liquid inlet and each valve core liquid outlet in each group, and the flow channels between the groups are mutually independent. The flow channels are not communicated with each other and are only connected with the valve core liquid inlet and the valve core liquid outlet which are mutually corresponding.
Because the valve core 2 is rotatably arranged in the shell 1, when the valve core 2 is driven by the driving component 3 to rotate to different preset angles, an inlet and an outlet of a flow channel in the corresponding valve core are corresponding to and communicated with the shell liquid inlet 101 and the shell liquid outlet according to preset rules. The preset rule refers to that at any preset angle, an independent flow channel is correspondingly arranged on the valve core, the upper inlet is communicated with the inlet of the shell, the outlet of the flow channel is communicated with the outlet of the shell, the communication mode realizes independent communication, and at the moment, other flow channels cannot be communicated with the inlet of the shell.
In some alternative implementations, the multi-way valve is configured as a three-way valve, and the upper peripheral surface of the housing 1 is provided with a housing inlet 101, and the lower peripheral surface is provided with three housing outlets, and the three housing outlets are the first housing outlet 102, the second housing outlet 103, and the third housing outlet 104 in a left-to-right sequence (the sequence is for convenience of explaining the structure of the three-way valve, and is only a matter of description in the drawings, and is not limited to the left-to-right sequence, but may be other angles or orientation sequences). Specifically, the flow channels in the valve core 1 include a first flow channel 203, a second flow channel 204, and a third flow channel 205, and the first flow channel, the second flow channel, and the third flow channel are not on the same plane, wherein: the first flow passage is provided with a first through hole A207 and a first through hole B208 on the circumferential surface of the valve core; the second channel is provided with a second through hole A029 and a second through hole B210 on the circumferential surface of the valve core; the third flow passage has a third through hole a211 and a third through hole B212 formed in the valve body peripheral surface.
The valve core forms a first notch 201 between the first through hole A207 and the position corresponding to the shell liquid inlet 101, and forms a second notch 202 between the second through hole A209 and the position corresponding to the shell liquid inlet 101. Because a shell liquid inlet is shared, in order to ensure that the runners are not communicated with each other, the first notch 201 and the second notch 202 can be formed in a staggered mode so that the first notch 201 and the second notch 202 are not communicated with the shell liquid inlet 101 at the same time, and the third through hole A211 is also not communicated with the first notch 201 and the second notch 202 in a staggered mode.
The valve core 2 is arranged inside the housing 1 and can rotate to a preset angle, namely: when the first through hole a207 is communicated with the housing liquid inlet 101 through the first notch, the first through hole B208 is communicated with the first housing liquid outlet 102; when the second through hole a209 is communicated with the housing liquid inlet 101 through the second notch 202, the second through hole B210 is communicated with the third housing liquid outlet 104; when the third through hole a211 communicates with the housing liquid inlet 101, the third through hole B212 communicates with the second housing liquid outlet 103.
In some implementations, the first and second flow passages 203, 204, and the third flow passage 205 are open in a radial direction of the spool. At this time, the radial direction corresponding to each opened flow passage may be different. The valve core structure can be more regular by arranging the flow channel in the radial direction, uneven thickness of two sides of the valve core flow channel due to the offset flow channel can be avoided, damage caused by abrasion after long-time use can be prevented, and the service life of the valve core is prolonged by the structure.
In order to enhance the sealing performance among the flow channels of the valve core, a sealing ring 4 is also arranged on the valve core of the multi-way valve. Specifically, this sealing ring 4 still includes: the first sealing ring, the second sealing ring, the third sealing ring and the fourth sealing ring. The first sealing ring is sleeved on the valve core 2 and is positioned at one end far away from the driving component 3; the second sealing ring is sleeved on the valve core 2 and is positioned between the first flow channel 203 and the third flow channel 205; the third sealing ring is sleeved on the valve core 2 and is positioned between the second flow passage 204 and the third flow passage 205; the fourth sealing ring is sleeved on the valve core 2 and is positioned at one end close to the driving component 3. The three flow passages are isolated by the four sealing rings, so that the condition that water is mutually communicated due to poor sealing property between the shell and the valve core is avoided.
Further optionally, a first sealing ring supporting bridge 213 is disposed on the first notch 201, and a second sealing ring supporting bridge 214 is disposed on the second notch 202. Because sealing washer 4 is mostly softer material, if adopt materials such as rubber, it has certain deformation, supports the bridge through two sealing washers and can support the sealing washer of the left and right sides respectively, has avoided leading to the gap between sealed case that can not be better and the casing because sealing washer atress warp, causes sealed effect not good.
In order to improve automation and reduce manpower to realize automatic control, the driving assembly comprises a motor and can drive the valve core to rotate to a preset angle in the shell to form different passages. And a sealing washer is arranged between the motor and the valve core, so that water is prevented from overflowing the three-way valve and even burning the motor.
