[0002] In a refrigeration and cold storage cooling ceiling or other products with a water circuit system, in order to meet the needs of the overall machine performance, one or more water circuits need to be provided in the water circuit system, and each water circuit needs to be able to be independently switched.

[0003] In the prior art, for example, in a refrigeration and cold storage cooling ceiling, in order to save costs, two water circuits need to be independently switched at four control nodes and share a heat exchanger.

[0004] However, the multiple water valve control scheme has high costs, and the difficulty of electrical control programming and debugging is large. The more complex the water circuit system is, the more obvious this problem becomes. Summary of the Invention

[0006] To solve the above problems, the present invention provides a switching valve, comprising:

[0007] A housing, an installation space is formed inside;

[0008] A valve core, arranged in the installation space, the valve core is rotatably arranged, a pipe body is suitable for being inserted between the inner wall of the housing and the valve core, a blocking structure protrudes from the outer wall of the valve core, and the blocking structure has a blocking position for pressing the pipe body and a release position away from the pipe body.

[0009] As a preferred solution, the valve core includes:

[0010] A fixing ring, the blocking structure is arranged on the outer periphery of the fixing ring.

[0011] As a preferred solution, there are several blocking structures; several blocking structures are arranged at intervals along the outer periphery of the fixing ring.

[0012] As a preferred solution, there are several fixing rings, and several fixing rings are arranged at intervals along the extending direction of the housing.

[0013] As a preferred solution, several blocking structures are arranged at an angle along the extending direction of the housing.

[0037] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Embodiment 1

[0039] As Figure 1 shown, this embodiment provides a switching valve, including a housing 1 and a valve core 2. An installation space 11 is formed inside the housing 1. The valve core 2 is arranged inside the housing 1 and is rotatably arranged. A pipe body is adapted to be inserted between the inner wall of the housing 1 and the valve core 2. A blocking structure 22 protrudes from the outer wall of the valve core 2. The blocking structure 22 has a blocking position for pressing the pipe body and a release position away from the pipe body. A blocking structure 22 is formed on the outer wall of the valve core 2. After the pipe body is inserted between the valve core 2 and the housing 1, the blocking structure 22 can be made to have a blocking position for pressing the pipe body and a release position away from the pipe body by rotating the valve core 2. When the blocking structure 22 is in the blocking position, the blocking structure 22 presses the pipe body, making the flow area inside the pipe body smaller. When the blocking structure 22 is in the release position, the blocking structure 22 does not press the pipe body, and the liquid flows normally inside the pipe body. By changing the position of the blocking structure 22, the flow area of the pipe body is controlled, thereby realizing the switching function of the pipeline. This solution has the advantages of simple structure and low cost.

[0040] As Figure 2 and Figure 3 shown, it should be noted that the shape of the protrusion is arc-shaped. In this embodiment, the height of the arc is the distance between the inner wall of the housing 1 and the valve core 2, ensuring that when the protrusion abuts against the pipe body, the pipe body is completely blocked and no liquid will flow through the pipe body. As an alternative embodiment, the shape of the protrusion can be square or frustum-shaped. As an alternative embodiment, the height of the protrusion can be less than the distance between the inner wall of the housing 1 and the valve core 2. Such a protrusion is provided to reduce the flow rate of the pipe body, thereby realizing the reduction of the pipeline flow rate. The height of the protrusion can be adjusted according to actual needs to meet actual requirements.

[0041] As Figure 4As shown in the figure, further, the valve core 2 includes a fixing ring 21, and the blocking structure 22 is disposed on the outer periphery of the fixing ring 21. The fixing and blocking structure 22 is fixedly connected. In this embodiment, to ensure the stability of the connection, an integrally formed manner is selected. As an alternative embodiment, the blocking structure 22 can also be connected to the fixing ring 21 by welding or bonding.

[0042] Specifically, there are several blocking structures 22, and several blocking structures 22 are disposed along the outer periphery of the fixing ring 21; in this embodiment, the blocking structures 22 are disposed opposite to each other on the outer periphery of the fixing ring 21, and two blocking structures 22 are disposed on one fixing ring 21, and the two blocking structures 22 are disposed opposite to each other on the outer periphery of the fixing ring 21. The two blocking structures 22 just abut against the water pipe 5 entering the housing 1 during use, and providing a blocking structure 22 can improve the blocking effect.

[0043] Specifically, there are several fixing rings 21, and several fixing rings 21 are spaced apart along the extending direction of the housing 1. A pipe body is correspondingly disposed on the outer periphery of each fixing ring 21. Several fixing rings 21 can correspond to several pipe bodies, so as to meet the simultaneous control of multiple pipelines. In this embodiment, there are two fixing rings 21, and the two fixing rings 21 are spaced apart along the extending direction of the housing 1. Blocking structures 22 are respectively disposed on the outer peripheries of the two fixing rings 21. The on-off states of two pipelines can be controlled by two sets of blocking structures 22. The two fixing rings 21 are manufactured by an integrally formed manner. As an alternative embodiment, they can also be connected by welding or bonding.

[0044] Specifically, the blocking structure 22 is disposed at an angle along the extending direction of the housing 1. In this embodiment, the included angle between the connection lines of the two blocking structures 22 on the outer periphery of the same fixing ring 21 and the connection lines of the two blocking structures 22 on the outer periphery of another fixing ring 21 is a right angle. When one set of blocking structures 22 is in the blocking position, the other set of blocking structures 22 is in the open state, so that a valve core 2 can control the different states of two pipe bodies, further increasing the practicability of the device.

[0045] As an alternative embodiment, the included angle between the connecting lines of the blocking structures 22 located on the outer periphery of different fixed rings 21 can also be an acute angle. By controlling the rotation of the fixed ring 21 to a specified position, the blocking effect of the blocking structure 22 can be achieved. For example, when the included angle between the connecting lines of two groups of blocking structures 22 is 45 degrees, when the first group of blocking structures 22 is in the blocking position, the second group of blocking structures 22 is in the release position. Then, the fixed ring 21 is rotated 45 degrees, and both groups of blocking structures 22 are in the release position. Then, the fixed ring 21 is rotated another 45 degrees, the first group of blocking structures 22 is in the release position, and the second group of blocking structures 22 is in the blocking position. By adjusting the included angle between the connecting lines of the blocking structures 22 on each two fixed rings 21, the on-off effect of the pipe body can be changed by rotating the fixed ring 21 at different angles. Further, the size of the included angle between the connecting lines of the blocking structures 22 on each two fixed rings 21 and the rotation speed of the fixed ring 21 can also be changed to achieve different states of the pipe body for different durations.

[0046] It should be noted that, as Figure 5 shown, there can also be four fixed rings 21. The four fixed rings 21 are all manufactured by an integral molding method. Blocking structures 22 are provided on the outer periphery of each fixed ring 21. The first layer of blocking structure 22 has one, which is arc-shaped. The blocking structure 22 of the second layer has one, which is frustum-shaped. The third layer of blocking structure 22 has two and is arranged oppositely. The blocking structure 22 of the fourth layer is arc-shaped and has two and is arranged oppositely. The shapes of the blocking structures 22 on the outer periphery of each fixed ring 21 can be the same or different, and the numbers of the blocking structures 22 on the outer periphery of each fixed ring 21 can also be the same or different, which are specifically designed according to actual needs.

[0047] Further, through holes 13 are provided on the side wall of the housing 1. The through holes 13 are suitable for the pipe body to pass through. In this solution, there are four through holes 13, and the four through holes 13 are divided into two groups, with each group arranged oppositely. In this embodiment, the through holes 13 are strip-shaped. It should be noted that the number of through holes 13 is twice the number of pipe bodies. The shape of the through holes 13 can also be changed in terms of size and shape according to the shape of the pipe body.

[0048] Further, a driving structure 3 is also provided. The driving structure 3 is fixed inside the housing 1, and the driving structure 3 is suitable for driving the valve core 2 to rotate. In the embodiment, the driving end of the driving structure 3 is fixedly connected to the valve core 2, and the bottom of the driving structure 3 is fixedly connected to the housing 1, so as to ensure the stability of the driving structure 3 during the process of driving the valve core 2 to rotate.

[0049] The driving structure 3 selects a stepper motor. The stepper motor has the advantages of accurate and stable transmission. By programming the number of steps of the stepper motor electronically, precise control of the valve core 2 can be achieved.

[0050] Furthermore, an installation structure 4 is also provided, and the installation structure 4 is connected to the housing 1; specifically, the installation structure 4 includes an installation plate 41 and installation columns 42. The installation plate 41 is generally arranged at one end of the housing 1, and the installation plate 41 is fixedly connected to the housing 1. In this embodiment, the installation plate 41 is welded to the housing 1. Specifically, there are two installation columns 42, and the two installation columns 42 are arranged at intervals on the installation plate 41. An installation space 11 is formed between the two installation columns 42, and the driving structure 3 is placed in the installation space 11. The driving structure 3 is fixed to the housing 1 by being clamped by the two installation columns 42. The driving structure 3 arranged in this way has the advantage of being convenient to disassemble.

[0051] Embodiment 2

[0052] A pipeline structure includes the on-off valve in Embodiment 1.

[0053] Furthermore, the pipeline structure includes water pipes 5. There are only two water pipes 5, and the two water pipes 5 are arranged at intervals along the axial extension direction of the housing 1, and the water pipes 5 penetrate the housing 1. The water pipes 5 are made of flexible materials and are bent into a U shape; both side arms of the water pipes 5 that are parallel to each other pass through the housing 1. The parts of the water pipes 5 located inside the housing 1 are arranged in contact with the inner wall of the housing 1.

[0054] It should be noted that the medium in the water pipes 5 is water in this embodiment. As an alternative embodiment, it can also be oil or other liquids, gases or solids.

[0055] It should be noted that the material of the water pipes 5 is rubber material, further polyethylene, or materials such as PVC.

[0056] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
