As shown in fig. 1, a control valve 100 according to an embodiment of the present invention includes a housing 20 and a valve element 50 (see fig. 4) installed in the housing 20, wherein a connecting portion 59 of the valve element 50 protrudes out of the housing 20 for receiving external driving to rotate relative to the housing 20.
As shown in fig. 1 and 2, the housing 20 includes a cylindrical main body 22 and a cover 28 attached to an open end of the main body 22, the valve chamber 24 is formed inside the main body 22, and the open end of the main body 22 is also an open end of the valve chamber 24. A cover 28 is mounted to the open end of the body 22 to close the valve cavity 24. The body 22 and the lid 28 are sealed with a first gasket 27 (see fig. 9). The cover 28 has a through hole 29 at the center for the connection portion 59 of the valve core to pass through.
The housing body 22 has several ports in communication with the valve chamber 24, including in this embodiment, side ports 31, 32, 34, 35 and 37 disposed in the sidewalls of the body 22, and an end port 38 disposed at the bottom of the body 22. In the present embodiment, the lateral interfaces 31, 32, 34, 35, and 37 are distributed from top to bottom along the height direction of the housing 20, specifically, the lateral interfaces 31 and 32 are located at the upper layer, the lateral interfaces 34 and 35 are located at the lower layer, and the lateral interface 37 is located at the lower layer. It should be noted that the present invention is not limited to the specific number and position of the interfaces.
Referring to fig. 2-5, the valve core 50 is rotatably mounted to the valve chamber 24. The valve body 50 can rotate in the valve chamber 24 with the axial direction of the connecting portion 59 as the rotation center axis. The valve core 50 is internally formed with a plurality of passages which form a plurality of communication holes 61, 62, 63, 64, 65, 66, 67, 68 in the surface of the valve core 50, including an end communication hole 68 in the end surface of the valve core 50 and lateral communication holes 61, 62, 63, 64, 65, 66, 67 in the circumferential surface of the valve core 50. The end communication aperture 68 is aligned with and communicates with the end interface 38. The lateral communication holes 61, 62, 63, 64, 65, 66, 67 are distributed from top to bottom in the axial direction of the valve body 50 and divided into three layers, specifically, the first layer includes the lateral communication holes 61, 62, 63, the second layer includes the lateral communication holes 64, 65, 66, and the third layer includes the lateral communication hole 67. The lateral communication holes 61, 62, 63, 64, 65, 66, 67 are aligned or misaligned with the corresponding lateral ports 31, 32, 34, 35, 37 during rotation of the valve cartridge 50, thereby closing or opening the corresponding passages of the valve cartridge 50, and thus closing or opening the corresponding lateral ports 31, 32, 34, 35, 37 of the housing. It is to be understood that, although the lateral communication holes of each layer are staggered from each other in the height direction (the rotational axial direction of the valve body 50) in the present embodiment, the present invention is not limited to this case, and it is also possible that adjacent two layers of lateral communication holes partially overlap in the height direction; similarly, the lateral communication holes of the same layer, such as the lateral communication holes 61, 62, 63, are not limited to be identical in height, nor are the sizes of the communication holes required to be identical.
To prevent leakage between the housing 20 and the valve spool 50, the control valve 100 further includes an annular seal 40. The sealing member 40 is fixedly mounted to the inner wall of the housing main body 22 to seal between the inner wall of the housing 20 and the outer wall of the valve cartridge 50 (see fig. 9). Specifically, the inner wall of the housing main body 22 is provided with an outward protruding clamping strip 26, the clamping strip 26 extends along the rotation axial direction of the valve core 50, the cross section of the clamping strip 26 is in a V shape, and the V-shaped opening faces the rotation center of the valve cavity 24; the outer wall of the sealing element 40 is provided with a concave clamping groove 46, and the clamping groove 46 also extends along the rotating axial direction of the valve core 50, so that the sealing element 40 can be arranged on the inner wall of the shell main body 22 along the rotating axial direction of the valve core 50, and the fixing is realized through the matching of the clamping groove 46 and the clamping strip 26. The seal 40 is provided with a plurality of through holes 43 aligned to align with corresponding lateral interfaces of the housing 22. Preferably, the seal 40 is further provided with an outwardly projecting flange 44 at the through hole 43, the flange 44 partially projecting into the corresponding lateral interface of the housing 22 to enhance positioning and leakage protection.
Preferably, the sealing member 40 is properly pressed by the valve core 50 to enhance the leakage prevention effect.
Referring to fig. 4 to 7, fig. 5 and 6 are schematic views of the valve core 50 shown in fig. 4 rotated by a certain angle around the direction F shown in fig. 4 so as to show the arrangement and communication of the communication hole of the valve core 50. In the present embodiment, the lateral communication holes 61, 62, 63, 64, 65, 66, 67 are also referred to as a first communication hole, a second communication hole, a third communication hole, a fourth communication hole, a fifth communication hole, a sixth communication hole, and a seventh communication hole, respectively, and the end portion communication hole 68 is also referred to as an eighth communication hole.
The lateral communication holes 61, 62, 63 of the first layer are communicated to the lateral communication holes 64 of the second layer through the first channel, the second channel, the third channel, respectively. Preferably, the channels run in a smooth transition to reduce pressure drop. For example, each passage includes an inclined section extending from the lateral communication hole 61, 62, 63 toward the inside of the spool 50 and inclined toward the end of the spool 50 having the end communication hole 68.
The lateral communication holes 65 and 66 of the second layer are connected to the end communication hole 68 through fourth and fifth passages, respectively, and the lateral communication hole 65 also communicates with the lateral communication hole 66 through a sixth passage.
The lateral communication 67 of the third layer is connected to the end communication hole 68 through a seventh passage. It will be appreciated that, since the end communication holes 68 communicate with the lateral communication holes 65, 66 of the second layer, the lateral communication 67 of the third layer also communicates with the lateral communication holes 65, 66 of the second layer. That is, the communication hole 67 communicates to the communication hole 65 and the communication hole 66 through the eighth passage, the ninth passage, respectively.
In the present embodiment, the width of the lateral communication holes 64, 65, 66 of the second stage in the rotational direction of the spool is larger than the width of the lateral communication holes 61, 62, 63 of the first stage in the rotational direction of the spool. More specifically, the width of the communication hole 64 is the largest, followed by the widths of the communication holes 65 and 66. The communication holes 61, 62, 63 and 67, 68 have a relatively small width, and preferably, the diameter of the communication holes is substantially the same as that of the interface of the housing 20.
When the valve core 50 is rotated by different angles relative to the housing 20, the lateral communication holes 61, 62, 63, 64, 65, 66, 67 are shielded by the housing 20 to different degrees, and thus have different operation modes. For example:
in the first operation mode, when the side port 35 of the housing 20 is fully opened by the communication hole 64 of the valve body 50, the side port 35 communicates with the side port 31 through the internal passage of the valve body 50, and the side port 34 communicates with the end port 38 through the internal passage of the valve body 50.
In the second operation mode, when the valve core 50 rotates counterclockwise by 20 degrees from the position of the first operation mode, a partial area of the side port 35 of the housing 20 is communicated with the communication hole 64 of the valve core 50, the side ports 35 and 37 are respectively communicated with the side port 31 through the corresponding internal passages of the valve core 50, and the side port 34 is communicated with the end port 38 through the internal passages of the valve core 50.
In the third operating mode, i.e., when the spool 50 is rotated 39 degrees counterclockwise from the position of the first operating mode, the side port 37 communicates with the side port 31 through the internal passage of the spool 50, and the side port 34 communicates with the end port 38 through the internal passage of the spool 50.
In the fourth operating mode, when the spool 50 is rotated 94 degrees counterclockwise from the position of the first operating mode, the side port 34 communicates with the side port 35 through the internal passage of the spool 50, and the side port 31 communicates with the end port 38 through the internal passage of the spool 50.
In the fifth operating mode, i.e., when the spool 50 is rotated 114 degrees counterclockwise from the position of the first operating mode, the side ports 35, 37 communicate with the side port 34 through the corresponding internal passages of the spool 50, respectively, and the side port 31 communicates with the end port 38 through the internal passages of the spool 50.
In the sixth operating mode, when the spool 50 is rotated by 133 degrees counterclockwise from the position of the first operating mode, the side port 34 communicates with the side port 37 through the internal passage of the spool 50, and the side port 31 communicates with the end port 38 through the internal passage of the spool 50.
In the seventh operating mode, when the spool 50 is rotated 188 degrees counterclockwise from the position of the first operating mode, the side port 34 communicates with the side port 35 through the internal passage of the spool 50, and the side port 32 communicates with the end port 38 through the internal passage of the spool 50.
Referring to fig. 7 to 9, in the present embodiment, the control valve 100 further includes a second sealing ring 81 for enhancing the sealing performance between the end communication hole 68 and the end interface 38 of the housing. The end communication hole 68 is tubular and the end is recessed to form a seal 57. The second sealing ring 81 is formed in a ring shape, is fitted to the sealing portion 57, and is sandwiched between the sealing portion 57 and the inner wall of the housing 22, thereby enhancing the sealing connection between the end communication hole 68 and the end connection port 38 of the housing.
The above examples only show the preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications, such as combinations of different features in various embodiments, may be made without departing from the spirit of the utility model, and these are within the scope of the utility model.
