[0002] When a traditional three-way valve is in use, the valve core of the three-way valve can rotate freely in the valve body, and the nurse or user can only judge whether it is connected by observing the arrow mark on the valve core; or the user may adjust the valve core multiple times to make the flow reach the maximum state or completely close it. Utility Model Content

[0003] The utility model provides a three-way valve which can be rotated and positioned to solve the problems raised in the above background technology.

[0004] To achieve the above purpose, the specific technical solution is as follows:

[0005] A rotatable positionable three-way valve comprises a valve body, in which a rotating plug is movably mounted, a side wall of the rotating plug is provided with an arc groove, two springs are fixedly mounted on the inner wall of the rotating plug, and an arc-shaped protrusion is fixedly connected to one end of the spring close to the rotating plug.

[0006] Specifically, three through grooves are formed through the three sides of the valve body and the rotary plug, and the valve body is fixedly connected to three pipes through the three through grooves. The outer wall of one end of the pipe away from the rotary plug is provided with a thread, and the pipe is rotatably connected to a water pipe through the thread.

[0007] Specifically, a sealing gasket is movably installed at the connection between the pipeline and the water pipe.

[0008] Specifically, a handle is fixedly connected to the top of the rotary plug.

[0009] Specifically, an indicator arrow is provided on the top of the handle.

[0010] Compared with the prior art, the beneficial effect of the utility model is at least that: through this technical improvement invention, the user (nurse) can not only judge whether it is connected by observing the indicator arrow mark, but also sense whether it is connected by touch through the engagement of the arc groove on the rotating plug and the arc protrusion, which is more convenient in actual work, greatly saves time and improves work efficiency.

[0015] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0016] like Figure 1-3 As shown, a rotatable positionable three-way valve comprises a valve body 1, a rotary plug 2 is movably installed in the valve body 1, an arc groove 3 is provided on the side wall of the rotary plug 2, two springs 4 are fixedly installed on the inner wall of the rotary plug 2, an arc shaped protrusion 5 is fixedly connected to one end of the spring 4 close to the rotary plug 2, when the rotary plug 2 is rotated, the arc shaped protrusion 5 is squeezed by the spring 4, so that the arc surface of the arc shaped protrusion 5 fits with the arc groove 3, and the rotation into place can be known by tactile sense.

[0017] Specifically, three through grooves are provided on three sides of the valve body 1 and the rotary plug 2, and the three through grooves are in a vertical state. The valve body 1 is fixedly connected with three pipes 6 through the three through grooves. Only one pipe 6 is used for water inlet, and the others are used for water outlet. One-way water flow can be achieved by rotating the rotary plug 2. The pipe 6 can be closed by aligning the only closed surface of the rotary plug 2 with the pipe 6 for water inlet. A thread 7 is provided on the outer wall of one end of the pipe 6 away from the rotary plug 2. The pipe 6 is rotatably connected with a water pipe 8 through the thread 7. A threaded groove corresponding to the thread 7 is provided on the inner wall of the water pipe 8. The water pipe 8 can be connected to the pipe 6 by rotating the water pipe 8.

[0018] A sealing gasket 9 is movably installed at the connection between the pipeline 6 and the water pipe 8. The sealing gasket 9 is preferably made of rubber. By providing the sealing gasket 9, water leakage at the connection between the pipeline 6 and the water pipe 8 can be avoided.

[0019] Specifically, a handle 10 is fixedly connected to the top of the rotary plug 2. The handle 10 is provided to facilitate the rotation of the rotary plug 2.

[0020] Specifically, an indicator arrow 11 is provided at the top of the handle 10 , and the indicator arrow 11 is provided to facilitate observation of the rotation direction of the rotary plug 2 .

[0021] Working principle and use process of the utility model: through this technical improvement invention, the user (nurse) can not only judge whether it is connected by observing the indicator arrow 11, but also feel whether it is connected by touch through the engagement of the arc groove 3 on the rotating plug 2 and the arc protrusion 5, which is more convenient in actual work, greatly saves time and improves work efficiency.

[0022] It should be understood that although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0023] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
