Problems solved by technology
[0003] When the existing devices detect and calibrate the water meter, the accuracy of the water meter is detected by the weight of the water flowing through the water meter per unit time. However, when the water meter is detected, it is necessary to The gas in the water is eliminated, and the water contains air bubbles, which will affect the calculation of the weight of the water flowing through the water meter per unit time, and affect the accuracy of the water meter detection, so it is necessary to eliminate the air bubbles contained in the water flowing through the water meter

The invention discloses a water meter detection and calibration device and belongs to the technical field of water meter detection equipment. The device comprises a water tank, a water pump, a pressure stabilizing tank, a water pipe, a flow display device, a pneumatic electromagnetic valve, a three-way reversing valve and an electronic scale; the water pump and the pressure stabilizing tank are horizontally arranged beside the water tank and are communicated with the water tank through the water pipe; an installation frame is arranged at the bottom of the flow display device; the flow displaydevice is arranged on the other side of the water tank through the installation frame; four water meter bodies are connected to the water pipe in series; two symmetrically-arranged supporting frames are arranged at the top of the water tank; and the three-way reversing valve is fixedly arranged at the tops of the two supporting frames; the electronic scale is horizontally arranged beside the watertank; a direct drainage pipe communicated with the water tank is arranged at the bottom of the three-way reversing valve; an exhaust pipe communicated with the direct drainage pipe is arranged on theside wall of the direct drainage pipe. According to the water meter calibration device, gas in water can be discharged, and the accuracy of water meter calibration is improved.
Description
technical field [0001] The invention relates to the technical field of water meter detection equipment, in particular to a water meter detection and calibration device. Background technique [0002] The flow verification standard device is a standard test bench used in the verification and calibration of flow meters. Its accuracy and stability greatly affect the measurement accuracy of the flow meters produced. It is a flow verification standard with high precision and good stability. The device can not only provide reliable technical basis for manufacturers, quality supervision departments and measurement technology institutions, but also provide accurate and unified measurement standards for the introduction of intelligent flowmeters in my country in the future. Water hammer phenomenon: In the pipeline with pressure, due to some external reasons (such as sudden closure of valves, sudden stop of water pump unit), the flow rate of water changes suddenly, which causes water ha...
