[0063] A buffer bin is provided between the central sphere 9 and the inner wall of the diverter spherical shell 13 , and the lower end of the buffer bin is connected to the two diverter bins 16 respectively.

[0064] The working principle and beneficial effects of this embodiment are as follows: the upper end of the central detection diverter groove 23 is directly opposite to the inlet pipe 14, and the pressure detection diverter 17 is inserted into the central detection diverter groove 23, and the diversion buffering effect after the pressure detection effect is realized through the pressure detection diverter 17, thereby effectively performing the buffering and pressure reduction effect in the first time.

When the flow pressure of the raw material is small, the pressure buffer detection seat 19 is squeezed and inserted upward into the central detection diverter groove 23 or the inlet pipe 14. The use of the pressure detection spring 21 effectively reduces the situation in which the ball friction in the ball valve principle is used hard, thereby effectively solving the problem of long-term hard friction between the balls or the sealing rings that easily causes wear and reduces the service life.
