middle valve body and the right valve body are connected by
stainless steel expansion pipe, and the left and middle valve
bodies are connected by three screw rods with trapezoidal threads
at both ends. If the three screw rods are rotated forward (or
backward) at the same time, the left and middle valve bodies are
compressed (or separated). A blind plate is arranged in the middle
of the upper and middle screw of the three screw rods, and the
blind plate rotates around the axis. The following two screw rods
are equipped with locating blocks of blind plate on the same part.
When the blind plate rotates, it can prevent the blind plate from
drifting and the seal ring from scratching. One screw rod is
equipped with worm wheel drive mechanism to realize the purpose of
loosening the clamping valve body.Main performance
