[0020] The anti-vortex direct-flow globe valve is a valve with a unique design and advanced functions, mainly used to control the opening and closing of fluids, and optimize the fluid flow through the anti-vortex design to reduce energy loss. Its specific working principle is as follows:

[0021] Structural composition

[0022] This globe valve mainly consists of the following components:

[0023] Valve body 1: Provides the structural framework for the entire valve.

[0024] Anti - vortex tube 2: Reduces the generation of vortices and optimizes fluid flow.

[0025] External connecting pipe 3: Connects to the pipeline system to enable the inflow and outflow of fluid.

[0026] Valve neck 4: Supports and protects the drive mechanism.

[0027] Valve ball 5: Controls the opening and closing of the fluid by rotation.

[0028] Valve ball support ring 6: Supports the valve ball to ensure its stable operation.

[0029] Drive handle 7: Achieves the opening and closing of the valve ball through manual rotation.

[0030] Working process

[0031] 1. Valve opening

[0032] When the valve needs to be opened, the operator rotates the drive handle 7. The drive handle transmits torque through the mechanical connection inside the valve neck 4, causing the valve ball 5 to rotate. The passage on the valve ball gradually aligns with the fluid passage, and the fluid begins to flow into the valve body 1 from one side, passes through the anti - vortex tube 2 and the valve ball support ring 6, then flows out of the valve body from the other side and enters the external connecting pipe 3, and finally enters the downstream pipeline.

[0033] 2. Valve closing

[0034] When the valve needs to be closed, the operator rotates the drive handle 7 in the reverse direction, and the valve ball 5 rotates accordingly, gradually making the passage perpendicular to the fluid passage. At this time, the fluid passage is completely blocked, and the fluid cannot pass through the valve body, achieving the closing of the valve.

[0035] Anti - vortex design

[0036] 1. Function of the anti - vortex tube 2

[0037] The anti - vortex tube 2 is fixedly installed at both ends of the valve body 1 and is designed with a buffer ring 23 and a mating interface 22. When the fluid passes through the anti - vortex tube, the design of the buffer ring 23 and the mating interface 22 makes the fluid flow more smoothly, reduces the generation of vortices, and thus reduces energy loss.

[0038] 2. Function of the valve ball support ring 6

[0039] The valve ball support ring 6 is made of nickel alloy, and there is a groove inside it that is consistent with the radian of the valve ball 5, which can closely adhere to the surface of the valve ball to ensure the stability of the valve ball during rotation. At the same time, the support ring can buffer the rotational force of the valve ball, reduce wear, and extend the service life of the valve.

[0040] Advantages and Effects

[0041] Through the above design, the anti-vortex direct-flow stop valve achieves the following advantages:

[0042] Reducing vortex: The vortex phenomenon of the fluid when passing through the valve is significantly reduced, improving the flow efficiency of the fluid.

[0043] Reducing energy consumption: Optimizing the fluid flow reduces the fluid resistance and the energy consumption of the system.

[0044] Extending the service life: The protective effects of the valve ball support ring and the anti-vortex tube reduce the wear of the valve ball and the valve body, extending the service life of the valve.

[0045] Improving sealing performance: The valve ball support ring provides a good sealing effect to prevent fluid leakage.

[0046] In summary, the anti-vortex direct-flow stop valve realizes the high efficiency, energy saving, and reliability of fluid control through its unique structural design and precise manufacturing process, and is an advanced valve with broad prospects in industrial applications.

[0047] Using the technical solution described in this utility model, or those skilled in the art being inspired by the technical solution of this utility model to design similar technical solutions and achieving the above technical effects shall fall within the protection scope of this utility model.
