Claim 9:
10. The buffer valve as claimed in claim 1, wherein the buffer valve includes a miniature valve body, a breathing cover and the floating ball; the miniature valve body has a cylindrical shape and includes the inner chamber, an outer chamber, a partition portion, and the outer gas hole; the breathing cover is configured to connect the breathing hole and includes an inner accommodating chamber, the inner gas hole, and an external thread; an external thread of the breathing cover is coupled and sealed with the breathing hole; the inner gas hole is located on the breathing cover at a position where the inner accommodating chamber deviates from the axis of the inner chamber and is proximate to the inner annular surface to communicate with the breathing hole; an outer ring surface of the miniature valve body is coupled and sealed with the inner accommodating chamber of the breathing cover; the outer chamber is configured to install the gas connector; the partition portion is located in the middle of the miniature valve body to separate the inner chamber and the outer chamber at two ends, the partition portion has the outer gas hole to communicate with the inner chamber and the outer chamber, and the outer gas hole is located on the axis; the shielding action is that when the weight W of the floating ball cannot resist the pressing force Fp, the floating ball is secured to the outer gas hole; the releasing mechanism is that when the weight W of the floating ball exceeds the pressing force Fp generated by the pressure difference ΔP, the floating ball is displaced to the inner chamber and no longer covers the outer gas hole; the releasing action is reliably completed due to the ratio of the outer diameter d1 of the floating ball to the inner diameter D2 of the inner chamber, d1/D2≤0.6; the outer diameter d1 of the floating ball is greater than the outer diameter d3 of the outer gas hole, and the cone angle 2θ, 10°≤θ≤60°; wherein the adjusting mechanism is configured to adjust parameters including the weight W and the outer diameter d1 of the floating ball and the cone angle 2θ.
