Of the present utility model realized by following technical principle：Pass through hold-carrying with pressure and the fluid of flow pulsation
Deflector type fluid flow straightener body is deflected on blue water inlet and baffle groups, when the pressure peak with pulse energy
Fluid matasomatism rolls into a ball cotton-shaped sheet nylon yarn or high elastic rubber after rolling into a ball on cotton-shaped sheet nylon yarn or high elastic rubber
Absorb the kinetic energy and elastic deformation occurs；Opposite, when pressure valley fluid matasomatism is rolling into a ball cotton-shaped sheet nylon yarn or high-elastic
After on property rubber, roll into a ball cotton-shaped sheet nylon yarn or high elastic rubber then discharges the kinetic energy and recovers elastic deformation.It is this according to
Attracted deposit and discharge the process of pulse energy by damping filler, stabilized the kinetic energy of pressure fluid, pressed so as to play to eliminate
The effect of power pulsation.Pulsating fluid is set to form spiral turbulent flow in body so as to reach the effect of compensator or trimmer pressure pulsation or flow pulsation
Fruit.
As it was previously stated, output flow caused by displacement type conveying equipment for fluid substances is pulsed, it is the type conveying equipment for fluid substances
Common feature.Deflector type fluid flow straightener described in the utility model is to form the rapids that is vortexed by baffle groups by fluid
Stream eliminates flow pulsation；In order to preferably form the equilibrium of output flow, load baffle groups in the body and damping is filled out
Fill after thing remaining volume should be not less than 2.5 times that one frequency of conveying equipment discharge liquid stream flow value, can so ensure
There are enough spaces a frequency is discharged after liquid stream converges buffering and form current stabilization.
Application process of the present utility model is that the utility model is serially connected in the port of export and transfer pipeline of pump or compressor
Centre is simultaneously fixed, you can plays a part of stabilizing and eliminating pressure and flow pulsation.
The utility model has the advantage of the fluid for being not only applicable to include two kinds of forms of liquid stream and air-flow, apply also for low
The frequency ripple frequency different with high frequency；With more it is simple in construction, without dynamic mobile parts, without consumable accessory it is non-maintaining and installation
The features such as easy to connect.
