Specifically, the outlet of the counterbalance valve is provided with pressure gauge.
Specifically, the tie point is provided with the second stop valve.
Specifically, second branch road is provided with the 3rd stop valve.
Specifically, the liquid feeding side of the membrane pump is additionally provided with air bleeding valve.
Specifically, the pipeline on the pipeline uses stainless steel flexible hose.
Specifically, first ripple damper and the second ripple damper are fixed on respective support, damping of pulsation
Vibration-absorptive material is lined between device and corresponding support.
Using above-mentioned technical proposal, the beneficial effect of technical solutions of the utility model is：
1st, the utility model being capable of smoothly the pipeline pulsation as caused by membrane pump and system using two ripple dampers
Water hammer, reduce the peak value of flow velocity fluctuation, protect pipeline, elbow, joint not to be pressurized the impact of fluctuation, reduce the energy of system
Consumption.
2nd, pressure gauge can show whether the hydraulic pressure of counterbalance valve rear pipeline has exception.
3rd, when ripple damper occurs abnormal, it is replaceable to close stop valve.
4th, air bleeding valve drives the gas being trapped in pipeline out of, ensures gettering efficiency.
5th, stainless steel flexible hose not only adapts to the mutual displacement of equipment connection end, additionally it is possible to absorbs vibrational energy, plays and subtract
Shake sound deadening.
6th, vibration-absorptive material can absorb the vibration energy of pulse damper housing, prevent to resonate.

Embodiment
The utility model is described in further detail with reference to specific embodiment.
As shown in figure 1, a kind of membrane pump damping device, including counterbalance valve 1, the membrane pump 2 and set gradually along pipeline
One stop valve 3, the liquid feeding side of membrane pump 2 are provided with the tie point for including the first ripple damper 4a, and the tapping side of membrane pump 2 is set
Having includes the second ripple damper 4b the second branch road.During 2 outlet of membrane pump, device is drawn liquid into from filling point；Membrane pump 2
During air inlet, counterbalance valve 1 can prevent liquid from being flowed toward filling point, but by the past liquor box of pressure.According to Boyle's law P1V1=
P2V2, pulsed by changing the volume of air chamber come smooth pipeline.It is averaged using the pre- inflated with nitrogen of preceding air chamber or argon gas, pressure for system
The 50%-80% of pressure.If at pump discharge, recommend the pressure of preliminary filling 50%, if at pump intake, recommend preliminary filling
70%-80%.There is the system of sine curve characteristic for flow velocity, during crest, chamber volume diminishes, and it is unnecessary that pulse damper absorbs
Flow liquid, during trough, chamber volume becomes big, the liquid of storage is discharged, so as to reach the effect smoothly pulsed.So
During the suction of membrane pump 2 is put, two ripple dampers smoothly the water hammer of pipeline pulsation and system as caused by membrane pump can show
As reducing the peak value of flow velocity fluctuation, protecting pipeline, elbow, joint not to be pressurized the impact of fluctuation, reduce the energy consumption of system.
As shown in figure 1, the outlet of counterbalance valve 1 is provided with pressure gauge 6.Pressure gauge 6 can show the hydraulic pressure of the rear pipeline of counterbalance valve 1
Whether exception is had, once maintenance can be made by exception occur.
As shown in figure 1, tie point is provided with the second stop valve 5a, the second branch road is provided with the 3rd stop valve 5b.When
When one ripple damper 4a occurs abnormal, replacing can be pulled down by closing the second stop valve 5a；Hindered when when the second pulsation
When Buddhist nun's device 4b occurs abnormal, replacing can be pulled down by closing the 3rd stop valve 5b.
As shown in figure 1, the liquid feeding side of membrane pump 2 is additionally provided with air bleeding valve 7.Membrane pump 2 may be inhaled when drawing liquid into
Enter some gases, the effect of membrane pump 2 will be influenceed in the course of time, at this moment can open air bleeding valve 7 and drive gas out of, ensure to inhale
Gas efficiency.
Pipeline on pipeline uses stainless steel flexible hose.Stainless steel flexible hose is a kind of flexible pressure-resistant Wear-resisting pipe fitting, and it weaves knot
The shell of structure makes it to can compensate for the mutual displacement of equipment connection end with large angle torsion, absorbs vibrational energy, can play
The effects such as damping, noise reduction buffering.
First ripple damper 4a and the second ripple damper 4b are fixed on respective support, ripple damper with it is corresponding
Support between be lined with vibration-absorptive material.Vibration-absorptive material can absorb the vibration energy of pulse damper housing, prevent to resonate.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this practicality
New protection domain.
