By twisting the flow limiting valve core, each through hole can correspond to each flow channel in the head flow channel. However, since the through holes on the flow limiting valve core are arranged perpendicular to each other, when one through hole is aligned with one flow channel, the other flow channel will be in a closed state, thereby achieving the purpose of fast switching of the medium inflow channel, saving time and improving work efficiency.

[0007] As a preferred embodiment of the utility model, the Y-type flow channel includes a converging flow channel, the first flow channel is connected to the converging flow channel through the first through hole, the second flow channel is connected to the converging flow channel through the second through hole, and the head flow channel is set as two independent flow channels, and finally both flow into the converging flow channel, so that the medium can be quickly switched into the channel through the flow limiting valve core.

[0008] As a preferred solution of the present utility model, the first through hole has the same size as the first flow channel, and the second through hole has the same size as the second flow channel, so as to ensure that the medium will not leak after flowing in.

[0009] As a preferred solution of the utility model, a mounting portion is provided on the valve body, the opening direction of the mounting portion is perpendicular to the opening direction of the head flow channel, and the mounting portion matches the flow limiting valve core to ensure that the valve core can be installed between the valve body.

[0010] As a preferred solution of the utility model, a handle is provided at one end of the flow limiting valve core away from the valve body, so as to facilitate the operator to control the flow limiting valve core.

[0011] As a preferred solution of the utility model, a pressure cover is provided on the valve body, and the pressure cover is located between the handle and the valve body, and is used to limit the displacement of the flow limiting valve core to prevent it from sliding out of the valve body.

[0012] As a preferred solution of the utility model, the flow limiting valve core body is a corrosion-resistant structural part, which increases the service life of the flow limiting valve core.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. The utility model is a Y-type three-way valve, which is formed by horizontally inserting a rotatable flow limiting valve core on the head flow channel of the Y-type flow channel, and the flow limiting valve core is provided with a pair of mutually perpendicular through holes. By twisting the flow limiting valve core, each through hole can correspond to each flow channel in the head flow channel. However, since the through holes on the flow limiting valve core are arranged perpendicular to each other, when one through hole is aligned with one flow channel, the other flow channel will be closed, thereby achieving the purpose of rapid switching of the medium inflow channel, saving time and improving work efficiency.

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] Example 1

[0022] like Figure 1-2 A Y-type three-way valve is shown, the valve includes a valve body 1, the valve body 1 has a built-in Y-type flow channel 11, the Y-type flow channel 11 includes a head flow channel 111, the head flow channel 111 includes two flow channels, and the head flow channel 111 is horizontally interspersed with a limiting flow valve core 2, the limiting flow valve core 2 and the head flow channel 111 are rotatably connected, the limiting flow valve core 2 is provided with a first through hole 21 and a second through hole 22 which are opposite to the flow channel position in the head flow channel 111, and the first through hole 21 and the second through hole 22 are opened perpendicularly to each other, so that when the limiting flow valve core 2 and the head flow channel After 111 is rotated and installed, the operator can rotate the flow limiting valve core 2 to align the first through hole 21 or the second through hole 22 with the flow channel in the head flow channel 111 to achieve the inflow of the medium. Since the first through hole 21 and the second through hole 22 are perpendicular to each other, when the first through hole 21 is aligned with the head flow channel 111, the flow channel at the second through hole 22 is closed. When the second through hole 22 is aligned with the head flow channel 111, the flow channel at the first through hole 21 is closed. In this way, the purpose of quickly switching the medium inflow channel can be achieved, while saving time and improving work efficiency.

[0023] As mentioned above, the Y-shaped flow channel 11 includes a confluence flow channel 112, and the head flow channel 111 includes a first flow channel 1111 and a second flow channel 1112. The first flow channel 1111 is connected to the confluence flow channel 112 through the first through hole 21, and the second flow channel 1112 is connected to the confluence flow channel 112 through the second through hole 22. By dividing the head flow channel 1111 into the first flow channel 1111 and the second flow channel 1112, and introducing the confluence flow channel 112, the media of the first flow channel 1111 and the second flow channel 1112 can flow into the confluence flow channel 112 independently, thereby realizing the diversion and confluence of the fluid. The first flow channel 1111 and the second flow channel 1112 are connected to the confluence flow channel 112 through the first through hole 21 and the second through hole 22, respectively. This structure provides flexibility in the through-hole connection. Such a design allows the valve core to adjust the flow direction of the fluid through the through hole while rotating, thereby increasing the operational control capability of the valve, such as Figure 1-2 shown.

[0024] As mentioned above, the first through hole 21 has the same size as the first flow channel 1111, and the second through hole 22 has the same size as the second flow channel 1112. By setting the size of the first through hole 21 to be the same as the size of the first flow channel 1111, and also setting the size of the second through hole 22 to be the same as the size of the second flow channel 1112, the situation in which the medium in the flow channel cannot flow in due to size problems can be avoided.

[0025] As mentioned above, the valve body 1 is provided with a mounting portion, the opening direction of the mounting portion is perpendicular to the opening direction of the head flow channel 111, and the mounting portion matches the flow limiting valve core 2;

[0026] Furthermore, a handle 23 is provided at one end of the flow limiting valve core 2 away from the valve body 1. By providing a mounting portion, the entire flow limiting valve core 2 can be installed with the valve body 1, and a handle 23 is provided at one end of the flow limiting valve core 2 away from the valve body 1, so that the operator can rotate the flow limiting valve core 2 more conveniently. Figure 3 shown.

[0027] As mentioned above, a gland 3 is provided on the valve body 1, and the gland 3 is located between the handle 23 and the valve body 1. By providing the gland 3 between the valve body 1 and the handle 23, the entire flow limiting valve core 2 is prevented from slipping out during use, causing the device to fail.

[0028] Furthermore, the gland 3 and the valve body 1 are connected by screws, such as Figure 1-2 shown.

[0029] As mentioned above, the body of the flow limiting valve core 2 is made of corrosion-resistant material to increase the service life of the flow limiting valve core 2.

[0030] Example 2

[0031] The present embodiment 2 is the use environment and method of the embodiment 1. The utility model is a Y-type three-way valve, including a valve body 1, a Y-type flow channel 11 is arranged inside the valve body 1, and a flow limiting valve core 2 is rotatably connected to the valve body 1, and the flow limiting valve core 2 is horizontally passed through the head flow channel 111 on the Y-type flow channel 11 (that is, the head of the Y-type flow channel, because the flow channel is Y-shaped, the head flow channel 111 includes two flow channels), and two mutually perpendicular through holes are opened on the flow limiting valve core 2, so that after the flow limiting valve core 2 is connected to the valve body 1, the flow limiting valve core 2 is automatically The device is located at the head flow channel 111 and passes through the head flow channel 111, and the through hole opened on the flow limiting valve core 2 can match the flow channel in the head flow channel 111, which is convenient for the inflow of the medium. Since the through holes on the flow limiting valve core 2 are opened perpendicularly to each other, when the operator rotates the flow limiting valve core 2 to align one of the through holes with one flow channel, the other through hole cannot correspond to the other flow channel, so that the flow channel is in a closed state, and the medium can only flow in from the opened flow channel. The device is easy to operate and has a simple structure, which reduces the workload of the operator and improves the work efficiency. Figure 1-2 shown.
