Detailed Description

Preferred embodiments of the present utility model will now be described in detail with reference to the accompanying drawings, which form a part hereof, and together with the description serve to explain the principles of the utility model, and are not intended to limit the scope of the utility model.

Referring to fig. 1 to 5, the three-way valve includes a housing 1, a control body 2, and a control shaft 3. The control body 2 is arranged in the shell 1 and is rotatably connected with the shell 1, and in the rotating process, the control body 2 and the shell 1 are kept sealed to avoid water leakage. The control shaft 3 is fixedly connected with the control body 2 and is rotatably connected with the shell 1, and the control body 2 can rotate around the axis of the control shaft 3 relative to the shell 1 through the control shaft 3 and is used for controlling the opening and closing of the three-way valve. The control shaft 3 extends from inside the housing 1 to outside the housing 1 to facilitate the user to rotate the control shaft 3 to rotate the control body 2, and a handle may be mounted on the control shaft 3 to facilitate the user's grip.

Wherein the housing 1 is formed with a water inlet 11, a first water outlet 12 and a second water outlet 13. The control body 2 is provided with a flow passage for water to pass through, and the flow passage is provided with a first port 21, a second port 22, a third port 23 and a fourth port 24 on the surface of the control body 2. In order to realize the function of independently opening and closing the first water outlet 12 and the second water outlet 13 and simultaneously opening and closing the first water outlet 12 and the second water outlet 13. When the control body 2 rotates relative to the shell 1, the first interface 21 is kept communicated with the water inlet 11, the second interface 22 and the fourth interface 24 can be simultaneously communicated with the first water outlet 12 and the second water outlet 13 respectively, and the third interface 23 can be communicated with the first water outlet 12 or the second water outlet 13.

In some embodiments of the present application, the three-way valve is designed as a ball valve, i.e. the control body 2 is in a ball-type structure, the housing 1 is in a ball-shell structure concentric with the control body 2, and the axis of the control shaft 3 passes through the center of the ball. The control body 2 can thus rotate in the housing 1 about the axis of the control shaft 3.

In some embodiments of the present application, the first port 21, the water inlet 11 and the control shaft 3 may be coaxially arranged, so that the first port 21 is always in communication with the water inlet 11 when the control body 2 is rotated.

In certain embodiments of the present application, the centers of the first water outlet 12, the second water outlet 13, the second interface 22, the third interface 23, the fourth interface 24 are coplanar and perpendicular to the axis of the control shaft 3. By means of the geographic concept, the three-way valve is analogous to the earth, the axis of the control shaft 3 penetrates through the north and south poles, and the first water outlet 12, the second water outlet 13, the second interface 22, the third interface 23 and the fourth interface 24 have the same dimension, so that any one of the second interface 22, the third interface 23 and the fourth interface 24 can be communicated with any one of the first water outlet 12 and the second water outlet 13 when the control body 2 is rotated.

In this embodiment, the connection lines between the centers and the centers of the first water outlet 12, the second water outlet 13, the second port 22, the third port 23, and the fourth port 24 are all perpendicular to the axis of the control shaft 3. Namely, the first water outlet 12, the second water outlet 13, the second interface 22, the third interface 23 and the fourth interface 24 are all arranged on the equator, and the dimension is zero.

And the included angle between the centers of the first water outlet 12 and the second water outlet 13 and the center of the sphere is equal to the included angle between the centers of the second interface 22 and the fourth interface 24 and the center of the sphere. Namely, the longitude difference between the first water outlet 12 and the second water outlet 13 is equal to the longitude difference between the second interface 22 and the fourth interface 24, so that the second interface 22 and the fourth interface 24 can simultaneously communicate the first water outlet 12 and the second water outlet 13, and the function of simultaneously discharging water from the two water outlets is realized.

In this embodiment, the centers of the first water outlet 12, the second water outlet 13 and the center of the sphere are on the same straight line, and the centers of the second interface 22, the fourth interface 24 and the center of the sphere are also on the same straight line. Namely the first water outlet 12 and the second water outlet 13, and the longitude differences of the second interface 22 and the fourth interface 24 are 180 degrees. Thus, the second interface 22 and the fourth interface 24 can be exchanged, namely the first water outlet 12 and the second interface 22 can be communicated with the second water outlet 13 and the fourth interface 24 simultaneously to realize the simultaneous water outlet of the two water outlets, or the first water outlet 12 and the fourth interface 24 can be communicated with the second water outlet 13 and the second interface 22 simultaneously to realize the simultaneous water outlet of the two water outlets.

The line connecting the center of the third interface 23 and the center of the sphere is perpendicular to the line connecting the center of the second interface 22 and the center of the sphere. I.e. the third interface 23 is arranged between the second interface 22 and the fourth interface 24 and differs from the second interface 22 by 90 deg.. In the present embodiment, the difference in longitude between the second interface 22 and the fourth interface 24 is 180 °, and the difference in longitude between the third interface 23 and the second interface 22 and the fourth interface 24 is 90 °.

In practice, each interface is sized to the outlet so long as the interface is partially coincident with the outlet, even if the axes are not coincident, the interface is in communication with the outlet. In the present embodiment, therefore, the second port 22, the third port 23, and the fourth port 24 have the same circular structure, and the diameter of the control body 2 is greater than or equal to (1/sin 22.5 °) times that performed by the second port 22. Thus either only the third port 23 communicates with the first water outlet 12 or the second water outlet 13, or the second port 22 and the fourth port 24 communicate with the first water outlet 12 and the second water outlet 13 simultaneously. The condition that the second interface 22 or the fourth interface 24 is communicated with the other water outlet when the third interface 23 is communicated with one water outlet is avoided.

The embodiment of the utility model has the following beneficial effects: the three-way valve is provided with four interfaces on the control body, one interface is used for being communicated with the water inlet, and one of the remaining three interfaces is used for being independently communicated with any one of two water outlets, so that the circulation of a single water outlet is realized; the other two interfaces are used for simultaneously communicating the two water outlets and enabling the two water outlets to simultaneously discharge water, so that the functional defect of the existing three-way valve is overcome.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
