  • Product Description
  • Detailed parameters
  • Snail fan-shaped blind valve is connected into one body through three screw rods, and the three valve bodies are respectively fixed on the base to form a rigid structure. The middle valve body and the right valve body are connected by stainless steel expansion pipe, and the left and middle valve bodies are respectively connected by three screw rods with left and right trapezoidal threads at both ends. If the three screw rods are rotated forward (or reverse) at the same time, the positive and middle valve bodies are compressed (or separated).

    A blind plate is installed in the middle of the three screw rods, and the blind plate rotates around the axis. The following two screw rods are installed with positioning blocks of the blind plate at the same position. When the blind plate rotates, it can prevent the blind plate from drifting and dislocating, and avoid the sealing rubber ring from scratching. One of them is equipped with a worm gear rotating mechanism to achieve the purpose of loosening the clamping valve body.
