AI Technical Summary
When the traditional shunt ball valve is not used for a long time in winter, the residual liquid is prone to freeze, which makes it difficult to open the valve, and the opening and closing of the branch runners change at the same time as the mainstream, making the scope of application smaller.
An anti-freeze shunt ball valve is designed to enable the opening and closing of the branch pipeline by setting up a ball-clustered branch pipeline, and the rotation of the joint hole of the control column is simplified to simplify the operation process, and the opening of the water circuit is controlled through the support spring to prevent the valve from being frozen.
It has achieved simplified operational procedures, a wide range of applications, and can independently open and close the ball and installation ring, reducing the entry of water into the guide tube, and preventing the opening difficulties caused by the valve being frozen.

[0010] In the above-mentioned anti-freezing flow-dividing ball valve, limit parts are provided at the ends of the guide pipes.
[0011] Compared with the prior art, the anti-freezing flow-dividing ball valve realizes the opening and closing of the branch pipeline by setting a rolling ball to be clamped with the branch pipeline, simplifies the operation process by rotating the control column to be fitted into the clamping hole, and operates the control column to move up and down by two support springs, so that the rotating ball and the installation ring are independently opened and closed. The limit part at the end of the guide pipe can reduce the entry of water liquid into the guide pipe, and controls the opening of the water path through a compression spring, further preventing the valve from being difficult to open due to freezing.
