Throttling ball convenient to open

By setting specially designed upper and lower baffles and a drain hole in the flow channel of the throttling ball valve, the problem of increased ball opening torque and reduced flow rate caused by impurity accumulation is solved, thereby improving the stability of the inner wall of the flow channel and the flowability of the medium.

AI Technical Summary

Technical Problem

After prolonged use, existing throttling ball valves accumulate more impurities in the groove, resulting in increased torque required for the ball to open, uneven stress on the valve stem, easy damage, and reduced medium flow, affecting flow efficiency.

Method used

Several upper and lower baffles are set in the flow channel. The lower baffles are equipped with symmetrical drain holes. The height of the holes is greater than the lowest point of the inner wall of the flow channel. The drain holes are designed to be close to the connection of the inner wall of the flow channel, with an inclined length and staggered position, which increases the complexity of the medium flow, creates medium interference, and removes impurities.

Benefits of technology

It stabilizes the ball's opening torque, reduces valve stem resistance, prevents valve stem damage, ensures media flow and flow rate, enhances the stability of the inner wall structure of the flow channel, and makes the media flow smoothly.

Abstract

According to the technical scheme, the throttling ball convenient to open is characterized in that a flow channel is formed in the throttling ball, a plurality of upper blocking edges and a plurality of lower blocking edges are arranged in the flow channel, and each lower blocking edge is provided with two lower drainage holes which are symmetrical relative to the vertical plane. The lower drainage holes are higher than the lowest point of the inner wall of the flow channel, and the problems that in the prior art, the ball opening efficiency is low, and an external valve rod is prone to damage are solved.
