Description

Technical Field

[0001] The utility model belongs to the technical field of three-way valves, in particular to a three-way valve. Background Art

[0002] As the connection center of various pipelines, the three-way valve has a wide range of applications. The difference between the three-way valve and the ordinary valve is that there is an outlet at the bottom. When the internal valve core is in different positions, the outlet is different. For example, when the valve core is at the bottom, the left and right are connected. When the valve core is at the top, the right outlet is blocked, and the left and bottom outlets are connected.

[0003] Three-way valves are divided into manual three-way valves and automatic three-way valves. Manual three-way valves are controlled by manually rotating the valve; automatic three-way valves are controlled by electric, pneumatic, hydraulic and other means, and can be connected to the automatic control system.

[0004] The hydraulic three-way valve has a simple structure and is easy to process, so its production cost is much lower than that of the valve controlled by the electric transmission mechanism. However, the hydraulic three-way valve still has defects. The hydraulic three-way valve is heavy, which makes it inconvenient to carry. It usually needs to be transported by special transportation equipment, which increases the cost. Utility Model Content

It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0041] Embodiment 1:

[0042] like Figure 1-Figure 3 As shown, this embodiment provides a three-way valve, including:

[0043] Three-way valve body 1;

[0044] The moving component 2 is arranged at the bottom of the three-way valve body 1 and is used to make the three-way valve move easily;

[0045] The mobile assembly 2 comprises:

[0046] The connecting portion 21 is arranged at the bottom of the three-way valve body 1;

[0047] The mounting groove 22 is formed on the connecting portion 21. There are two mounting grooves 22, which are symmetrically distributed.

[0048] The support column 23 is movably disposed in the mounting groove 22;

[0049] Universal wheels 24, arranged at the bottom of the support column;

[0050] The locking portion 25 is disposed on the support column 23 and is used to lock the support column 23 on the connecting portion 21 .

[0051] In the present technical solution, the three-way valve body 1 is the main part of the device, which is used to control the flow direction and flow rate of the fluid. The moving assembly 2 is located at the bottom of the three-way valve body 1, and its function is to make the three-way valve move easily. The moving assembly 2 includes a connecting portion 21, a mounting groove 22, a pillar 23, a universal wheel 24 and a locking portion 25; the connecting portion 21 is located at the bottom of the three-way valve body 1, and is used to support the moving assembly 2. The mounting groove 22 is opened on the connecting portion 21, and there are two of them and they are symmetrically distributed, and are used to accommodate the pillars 23. The pillars 23 are components that are movably arranged in the mounting grooves 22. The universal wheels 24 are arranged at the bottom of the pillars 23 to provide directional flexibility during movement. The locking portion 25 is arranged on the pillars 23, and is used to lock the pillars 23 on the connecting portion 21 to ensure the stability of the moving assembly 2.

[0052] When the three-way valve needs to be moved, the operator can easily move the three-way valve to the desired position through the universal wheel 24. The moving process is more flexible, making the operation more convenient. At the same time, to ensure stability during the moving process, when the three-way valve is moved to the position where it needs to be used, the moving component 2 can be disassembled through the first locking part 25, and then the three-way valve can be used. In this way, the three-way valve can be easily moved to the desired position, the movement is more flexible, and the operation is convenient. After the three-way valve is moved to the desired position, the moving component 2 can be disassembled, so that the moving component 2 can be reused while using the three-way valve.

[0053] Embodiment 2:

[0054] This embodiment provides a three-way valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] like Figure 3 As shown, in this embodiment, the locking portion 25 is optimized to include:

[0056] There are multiple locking holes 31, which are evenly spaced along the circumferential direction and are opened on the outer side of the upper end of the support 23;

[0057] The limiting plate 32 is sleeved on the upper end of the support 23 and located on the connecting portion 21;

[0058] The number of the positioning holes 33 is the same as that of the locking holes 31 and they correspond one to one. The positioning holes 33 are formed on the limiting plate 32;

[0059] The first screw 34 is threadably disposed in the positioning hole 33 , and the first screw 34 extends into the locking hole 31 .

[0060] In the present technical solution, the limit plate 32 is locked on the pillar 23 by the first screw 34, and the limit plate 32 is in contact with the connecting portion 21, so that the limit plate 32 can limit the pillar 23, thereby limiting the position of the pillar 23 fixed on the connecting portion 21, so that the universal wheel 24 is fixed on the three-way valve body 1, and the three-way valve is easily moved to the desired position by the universal wheel 24. When the three-way valve body 1 is moved to the desired position, the first screw 34 is unscrewed, and the first screw 34 is out of contact with the locking hole 31. At this time, the limit plate 32 can be removed from the pillar 23, and then the pillar 23 is removed from the mounting groove 22. In this way, the universal wheel 24 is removed from the three-way valve body 1, which is convenient for the subsequent use of the three-way valve body 1.

[0061] Embodiment 3:

[0062] This embodiment provides a three-way valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0065] like Figure 1 As shown, in this embodiment, the three-way valve body 1 is optimized to be provided with an electromagnetic reversing valve 6 connected to the valve stem 43 , and the electromagnetic reversing valve 6 is used to control the switching opening and closing of the three-way valve body 1 .

[0066] In the present technical solution, when the electromagnetic reversing valve 6 is in a state, the three-way valve will be in a working mode. For example, the fluid flows from the first channel 52 into the spherical inner cavity 51, passes through the T-shaped channel of the valve core 42, and finally flows out of the second channel 53 or the third channel 54. By controlling the state of the electromagnetic reversing valve 6, the working mode of the three-way valve can be changed, so that the fluid can be switched between different channels to achieve flow direction conversion and flow rate regulation. Therefore, the three-way valve realizes the regulation of fluid flow direction and flow rate through the position of the valve core 42 and the control of the electromagnetic reversing valve 6. It has flexibility and controllability and is suitable for a variety of fluid control scenarios.
