Claim 19:
20. The buffer valve as claimed in claim 19, wherein in the process from the open state to the closed state for the normally closed valve and in the process from the closed state to the open state for the normally open valve, the period of time is that when the high-pressure gas is released, the shielding time Δt of the buffer valve is to slow down the pressure shock wave generated by the release of the high-pressure gas in the whole process: the approach speed of the central portion of the diaphragm of the normally closed valve toward the valve seat is reduced in the whole process to reduce impact and to reduce jet flow generated by the valve seat when it is closed: the leaving speed of the central portion of the diaphragm of the normally open valve away from the valve seat is reduced in the whole process to slow down generation of local negative pressure and reduce generation of eddy flow and turbulent flow.
