Description

Technical Field

[0001] The utility model relates to the technical field of ball valve seats, in particular to a ball valve seat capable of adjusting flow. Background Art

[0002] A ball valve is a check valve with a rotating transmission mode. Its key internal components are the ball and the valve seat. The function of the valve seat is to withstand the medium pressure and ensure the sealing of the ball during operation. The key indicators of the ball valve seat include sealing performance, water hammer resistance, wear resistance, etc. According to the different positions of the ball valve seat, it can be divided into fixed ball valves and floating ball valves. Fixed ball valves often use elastic materials, and the valve seat and the ball are fitted together through the pressure of the valve body to achieve sealing, while the floating ball valve seat achieves a close fit with the ball through an elastic assembly structure. The valve seat and the valve body do not produce direct vibration, thereby improving water hammer resistance and reducing the extrusion of the valve body.

[0003] Existing flow regulating ball valves generally achieve flow regulation by opening a V-shaped hole in the ball of the ball valve. This type of ball valve is used in chemical, petroleum, gas, metallurgy, electronics and other places where the regulation accuracy is not high, and it can fully meet the use requirements. However, in some occasions where high-precision flow control is required, due to the angular stroke of the valve, dead zones are easily generated, and the precision regulation cannot meet the process requirements.

[0004] Therefore, it is particularly important to improve the existing adjustable flow ball valve seat, design a new adjustable flow ball valve seat to solve the above technical defects, and improve the practicality of the overall adjustable flow ball valve seat. Utility Model Content

The first rotating plate 602 is installed outside the rotating piece 601, the control board 603 is installed outside the first rotating plate 602, the clamping plate 604 is installed inside the control board 603, and the second rotating plate 605 is installed on the control board 603 away from the first rotating plate 602. On one side, the connecting disk 606 is installed on the outside of the second rotating plate 605, and the main board 607 is installed on the outside of the connecting disk 606. When high-precision flow control is required, the first rotating plate 602 is rotated by rotating the rotating plate 601, and the second rotating plate 605 is driven to rotate at the same time. The clamping plate 604 is moved simultaneously by the first rotating plate 602 and the second rotating plate 605, so that the clamping plate 604 can open and close inside the control board 603, thereby realizing the water flow out from the inside of the main board 607.
