Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of reflux regulator, including high-pressure pump 1,
The inlet and liquid outlet of high-pressure pump 1 are connected separately with inlet tube 2 and outlet tube 3, the outer wall welding of inlet tube 2 and outlet tube 3
There is return pipe 4, outlet tube 3 and the pipeline of return pipe 4 or so are provided with the first electrical ball valve 5,6 and of first pressure sensing device
Second electrical ball valve 7, second pressure sensing device 8, the output end of first pressure sensing device 6 and second pressure sensing device 8
It is electrically connected with converter 9, the output end of converter 9 is electrically connected with controller 10, and controller 10 is respectively with first
Electrical ball valve 5 and the second electrical ball valve 7 are electrically connected.
Wherein, return pipe 4 is U-shaped return pipe, reduces the impact force that 4 bending part of return pipe is subject to, the inlet of high-pressure pump 1
It is connected by ring flange between liquid outlet and inlet tube 2 and outlet tube 3, and is provided with rubber gasket between ring flange,
Easy for installation, inlet tube 2, outlet tube 3 are identical with the inner diameter values of return pipe 4, so that the right side of the left end of outlet tube 3 and return pipe 4
Pressure values in end are identical.
Working principle: the present apparatus is connected into power supply, controller 10 uses AT89C52 type, and low-voltage, high-performance can be repeatedly
Erasable, first pressure sensing device 6 and the second electric press sensing device 8 are all made of MAT316 type, and wear-and corrosion-resistant is anti-interference,
Performance is stablized, and can install pressure gauge additional, be programmed to controller 10, so that controller 10 meets acquisition and the output end of receiving end
Control, first pressure sensing device 6 and the second electric press sensing device 8 are by 9 real-time Transmission signal of converter to controlling
Device 10 processed, in use, water is pumped into out liquid by inlet tube 2 by the first electrical ball valve 5 of opening and the second electrical ball valve 7, high-pressure pump 1
In pipe 3, the moment that high-pressure pump 1 starts will impact equipment, reduce the impact force that high-pressure pump 1 is discharged by return pipe 4,
Reduce outlet tube 3 pressure, when 1 steady operation of high-pressure pump, close the second electrical ball valve 7, at this time water flow by outlet tube 3 into
