Detailed Description

The following description is given by way of example only, and is not intended to limit the scope of the invention.

Referring to fig. 1 to 7, which show a preferred embodiment of the present invention, the butterfly valve of the present invention includes a body 1 and a disc 2.

The body 1 at least comprises a first flow channel 11, a second flow channel 12 and a third flow channel 13, wherein the first flow channel 11, the second flow channel 12 and the third flow channel 13 are communicated.

The disc 2 is in an elliptical sheet shape and comprises a long axis 21 and a short axis 22, and the disc 2 is pivoted in the body 1 and can swing between a first position and a second position.

When the disc 2 is located at the first position (as shown in fig. 5), the disc 2 blocks the communication between the first flow channel 11 and the third flow channel 13 and does not block the communication between the first flow channel 11 and the second flow channel 12; when the disc 2 is located at the second position (as shown in fig. 7), the disc 2 blocks the communication between the first flow channel 11 and the second flow channel 12 and does not block the communication between the first flow channel 11 and the third flow channel 13; in addition, when the disc 2 swings to the middle position between the first position and the second position (as shown in fig. 6), the disc 2 does not block the first flow channel 11, the second flow channel 12 and the third flow channel 13 from communicating with each other, so as to connect the fluids in the three flow channels. Therefore, the present invention only needs to provide a single disc 2 to effectively control the communication relationship between the plurality of pipelines, which can replace the conventional method of installing a plurality of valves to control the communication degree between the plurality of pipelines, and the structure of the disc valve is simple and is not easy to fail.

Specifically, the disc 2 is pivoted in the body 1 in the axial direction of the rotation of the short shaft 22, the body 1 is provided with two opposite through holes 18, two rotation shafts 4 are respectively pivoted in the two through holes 18 along the axial direction and are assembled with the disc 2, so that the disc 2 can rotate smoothly, and the two rotation shafts 4 can prevent fluid from leaking from the two through holes 18 to the outside. Preferably, a rotating member 5 is connected to the rotating shaft 4 and located outside the main body 1 to rotate the disc 2, and the rotating member 5 can be connected to a motor or other rotating means.

Furthermore, the first flow channel 11, the second flow channel 12 and the third flow channel 13 are distributed along the rotation circumference of the disc 2, so that the disc 2 can control the communication between the first flow channel 11 and the second flow channel 12 or the communication between the first flow channel 11 and the third flow channel 13 by rotating. Wherein the second flow channel 12 and the third flow channel 13 are located at two opposite radial ends of the short shaft 22 viewed along the axial direction.

In addition, the main body 1 includes a first pipeline 15, the disc 2 is pivoted in the first pipeline 15, and the first flow channel 11 is disposed at one end of the first pipeline 15. In the embodiment, the length of the disc 2 along the short axis 22 is the same as the diameter of the first pipeline 15, and the inner wall of the first pipeline 15 is a circular pipe.

Preferably, the body 1 further includes a second pipeline 16 and a third pipeline 17, the second pipeline 16 and the third pipeline 17 are transversely communicated with two opposite sides of the middle section of the first pipeline 15, the second flow channel 12 is disposed on the second pipeline 16, and the third flow channel 13 is disposed on the third pipeline 17. In detail, the disc 2 does not extend into the second and third pipes 16 and 17 when swinging between the first and second positions, and the length of the disc 2 along the long axis 21 is greater than the pipe diameters of the second and third pipes 16 and 17, so as to reliably block the communication between the first and third flow channels 11 and 12 or the communication between the first and third flow channels 11 and 13.

It should be noted that the butterfly valve further includes a fourth flow channel 14, the fourth flow channel 14 is disposed at an end of the first pipeline 15 opposite to the first flow channel 11, wherein when the disc 2 is located at the first position, the disc 2 abuts against an upper half portion of the first flow channel 11 and a lower half portion of the fourth flow channel 14, and the third flow channel 13 is communicated with the fourth flow channel 14, as viewed along the axial direction (as shown in fig. 5 to 7); when the disc 2 is located at the second position, the disc 2 is pressed against the lower half of the first flow channel 11 and the upper half of the fourth flow channel 14, and the second flow channel 12 is communicated with the fourth flow channel 14, so that a more diversified communication effect can be achieved.

It should be noted that the main body 1 is a four-way pipe, the first flow channel 11 is in a straight line communication with the fourth flow channel 14, the second flow channel 12 is in a straight line communication with the third flow channel 13 and is transverse to the first flow channel 11 and the fourth flow channel 14, and the distribution and arrangement relationship among the first flow channel, the second flow channel, the third flow channel and the fourth flow channel may be in other forms in other embodiments. In other embodiments, the first pipeline 15A of the main body 1A may not have the fourth flow channel, and the main body 1A is a tee (as shown in fig. 8), which is not limited thereto.
