It is expensive, and certain correct operation is needed in its use；Wetted liquid flowmeter, or liquid volume is directly surveyed with drainage, or
Person needs water as airtight substance, although usually cost is relatively low, because liquid is needed through water, can be generated to liquid component
It influences, and needs often to safeguard flowmeter；Hall flow meter is imitated by the Pneumatic rotor of similar fan using Hall
Flow velocity measurement should be completed, then carries out with the sectional area of pipeline calculating flow and volume, the meeting when flow velocity is relatively low or frequent fluctuation
Large error turbine flowmeter is generated, will will produce very in the larger fluid such as bio-oil fuel of measurement air-liquid mixed phase or viscosity
Big error.In more accurate industrial production measures, need precision higher, cheap and the larger liquid of viscosity can be measured
Flowmeter.
Utility model content
The goal of the invention of the utility model is to provide a kind of gear piston formula flowmeter, it is intended to solve typical commercial application
Flowmeter in error it is larger, complicated, of high cost and be not applied for year larger liquid problem.
To realize the goal of the invention of the utility model, the technical solution taken is as follows.
A kind of gear piston formula flowmeter, it is characterised in that：
It is assembled by piston, piston axis, power gear, cylinder body, solenoid valve, control circuit；The cylinder interior
One piston is set, and the piston is connected to piston axis, and the piston axis is connected to rack outside cylinder body by fixing piece, institute
It states and is fitted into power gear on rack, the cylinder body is connected in parallel on the both ends of solenoid valve combined pipeline, the solenoid valve combined pipeline
Both ends connect inlet and liquid outlet respectively.
The further limits scheme of the utility model is：
Further, the solenoid valve combined pipeline, can by four Through solenoid valves or two three-way magnetic valves,
Or two-position five-way formula solenoid valve is realized.
Further, the circuit control between control circuit described in the utility model and solenoid valve, can be by relay
Circuit control can also use PLC to control.
Further, the liquid of gear piston formula flowmeter system described in the utility model metering can be flow it is small,
The larger bio-oil fuel of viscosity.
Further, gear piston formula flowmeter system described in the utility model can be applied to small household kitchen range
On, solve the problems, such as that kitchen range block.
The beneficial effects of the utility model：It is this system simple structure, at low cost and easy to use；This system metering is accurate,
Also can guarantee that liquid itself and its flow behavior are unaffected, there is a better anti-current amount fluctuation, and can metered flow it is small and
The big liquid of viscosity.This system has the suction of a 0.1Mpa i.e. standard atmospheric pressure, can effectively dredge liquid, prevents from blocking up
Plug.
Description of the drawings
Specific implementation mode is further described below in conjunction with the accompanying drawings, wherein：
Fig. 1 is a kind of structural schematic diagram of gear piston formula flowmeter system of the utility model.

Specific implementation mode
Case 1 is embodied：
Gear piston formula flowmeter bodies described in the utility model, it is characterized in that：It includes piston 1, piston axis 2, moves
Powershift gear 3, cylinder body 4, solenoid valve 5,6,7,8；A piston 1 is arranged in 4 inside of the cylinder body, and the piston 1 is connected to piston axis
2, the piston axis 2 is connected to rack 11 outside cylinder body 4 by fixing piece, and power gear 3 is fitted on the rack 11, described
Cylinder body 4 be connected in parallel on the both ends of solenoid valve combined pipeline, the both ends of the solenoid valve combined pipeline connect inlet 9 and go out liquid respectively
Mouth 10.So drive the piston 1 being mutually connected with rack 11 that can be moved along fixation locus in cylinder body 4 by power gear 3.
The concrete operating principle of the present embodiment is：
The liquid volume that one stroke cylinder body of piston motion is discharged is constant, is flowed by liquid after system relevant
Physical parameter will not change.Therefore it can be obtained by operating counting how many times to the counting of piston motion number or to synchronous motor
Go out the flow of liquid.
Such as Fig. 1, after circuit is connected, when piston moves to the left, solenoid valve 5,8 is closed, and solenoid valve 6,7 is opened, liquid
Under the thrust of piston, it is transported to liquid outlet through solenoid valve 6, and is at this moment negative pressure in piston right ventricle, makes the liquid of inlet tube,
It is drawn onto piston right ventricle by solenoid valve 7.When piston moves to the right, solenoid valve 6,7 is closed, and solenoid valve 5,8 is opened, and liquid exists
Under the thrust of piston, it is transported to liquid outlet through solenoid valve 8, and is at this moment negative pressure in the left room of piston, makes the liquid of inlet tube, passes through
It crosses solenoid valve 5 and is drawn onto the left room of piston.For piston in this way in side-to-side movement, the liquid of inlet tube is constantly transported to liquid outlet.
The flow of liquid is so obtained by the counting of piston motion number or operating counting how many times to synchronous motor.
The better embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
