Specific embodiment:
As a preferred embodiment of fluid pulse rectifier of the present invention, as shown in Figure 1, 2, fluid pulse rectifier includes whole
Device matrix 1, pulse buffer film 2 are flowed, buffer film fixing piece 3 inputs pipe connections 4, exports pipe connections 5, the fixed spiral shell of pulse film
Silk 6；
It is hollow fluid cavity 16 at the middle part of rectifier matrix 1, two sides are respectively arranged with input screw thread and connect on rectifier matrix 1
Mouth 11 and output hickey 12, input hickey 11 are connected to output hickey 12 with fluid cavity 16, input screw thread and connect
Mouth 11 is connected with input pipe connections 4, and output hickey 12 is connected with output pipe connections 5, inside fluid cavity 16
It is provided with the buffering output of the wing 13 12 two sides of hickey at input hickey 11 and is respectively arranged with left rectifying wings 14 and right rectification
The wing 15, along buffer film positioning convex platform 17 is provided on fluid cavity 16, rectifier matrix 1 is evenly distributed in several fixing threaded holes
18。
Pulse buffer film 2 is fixed on the buffer film positioning convex platform 17 of rectifier matrix 1, and passes through buffer film fixing piece 3
It is positioned with buffer film locating slot 32, while using several pulse film fixed screws 6 by buffer film fixing piece 3 and pulse buffer film
