As a kind of improvement, be provided with the pressurized air surge tank between described buffer tank and described air compressor.
As a kind of improvement, described admission line is provided with variable valve.
As further improvement, described buffer tank is provided with the pressure transducer for detection of described water delivering orifice hydraulic pressure, and described pressure transducer is connected with described variable valve electricity.
Owing to having adopted technique scheme, the beneficial effects of the utility model are: because the water inlet of buffer tank and water delivering orifice respectively connect water inlet pipe and rising pipe, the position of this water delivering orifice is higher than the position of water inlet; The top of this buffer tank is provided with admission line, and this admission line is connected with air compressor.Enter buffer tank from air compressor pressurized air out, make the pressure stability in buffer tank and make the liquid level of WATER AS FLOW MEDIUM remain at a relatively constant height, thereby the WATER AS FLOW MEDIUM flow velocity that flows out from buffer tank upper water-out pipe is uniform and stable, and then it is uniform and stable to enter calibrated meter pipeline medium water flow velocity, guaranteed that simultaneously the WATER AS FLOW MEDIUM that enters or pass back in buffer tank does not affect the stability that flows out WATER AS FLOW MEDIUM from rising pipe from water inlet pipe, realize voltage stabilization and current stabilization, effectively improved the accuracy of calibration, also realized simultaneously open cycle or closed the circulation calibration.
Owing to being provided with the pressurized air surge tank between buffer tank and air compressor, thus realize to from air compressor out the pressurized air of pressure transient cushion, guarantee that the compressed air pressure that enters in stabilivolt is constant.
Because admission line is provided with variable valve, thereby when the pressure in buffer tank is higher or on the low side when affecting calibration, make the compressed air require that enters in buffer tank reduce or raise by the aperture of regulating variable valve, make that in buffer tank, pressure remains in the scope of calibration regulation.
Because buffer tank is provided with pressure transducer for detection of water delivering orifice hydraulic pressure, this pressure transducer is connected with the variable valve electricity.Detect in real time the pressure in buffer tank exit by pressure transducer, thereby when pressure during higher or lower than setting value, pressure transducer passes to variable valve, the aperture of automatic control and adjustment valve, realize robotization control, avoid the drawback of the error of artificial adjusting appearance, further guaranteed the constant pressure in buffer tank.
