[0002] A water meter is an instrument for measuring water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meter and velocity water meter. It originated in the UK and has a history of nearly two hundred years. When choosing the specifications of a water meter, you should first estimate the size and range of the flow rate normally used, and then choose the water meter with the specification that is closest to the commonly used flow rate as the first choice. The effectiveness of a water meter is usually verified by appearance inspection, tightness inspection, and pointer flexibility inspection.

[0030] Example: Reference Figure 1-4 A water meter rapid validation device shown in the figure comprises an operating table 1, two side plates 3 are fixed on the upper surface of the operating table 1, two movable plates 4 are slidably fitted between the two side plates 3, a plurality of groups of guide rods 13 are slidably penetrated on one side of the movable plate 4, a clamping plate 16 is fixed at one end of each group of guide rods 13, and a group of springs 14 are fixed between the clamping plate 16 and the movable plate 4;

[0031] Vertical plates 5 are fixed on both sides of the upper surface of the operating table 1, and a water pipe 6 is fixed through the vertical plates 5. One end of the water pipe 6 is rotatably connected to a water storage plate 7, and the water pipe 6 is connected to the inner cavity of the water storage plate 7. The end surface of the water storage plate 7 close to the movable plate 4 is fixedly connected to a plurality of docking hoses 10, and a plurality of groups of clamping plates 9 for fixing the docking hoses 10 are fixedly installed on the peripheral side of the water storage plate 7. A valve 11 is fixedly installed on the docking hose 10. Two groups of support columns 12 are fixed to the lower surface of the operating table 1, one end of the water pipe 6 is fixedly connected to an external pipe 8, and the free ends of the plurality of docking hoses 10 are provided with different docking joints, and a water storage cavity is provided inside the water storage plate 7.

[0032] When the water meter is tested by the device, the water meter is placed on the upper surface of the operating table 1, and the two movable plates 4 are controlled to approach each other, so that a plurality of clamping plates 16 contact the outer surface of the water meter. Through the contraction and deformation of the spring 14, different clamping plates 16 clamp and fix different parts of the water meter, so as to adapt to the irregular outer side of the water meter. The water storage plate 7 is rotated and a docking hose 10 with different docking joints is selected as needed. The docking hose 10 is removed from a set of card plates 9, and the docking joint of the docking hose 10 is connected to the water inlet (water outlet) of the water meter. The opening of the docking hose 10 can be controlled by the valve 11, and the docking installation of the water meter is completed.

[0033] One of the external pipes 8 is connected to the water tank, and the water tank stably delivers clean water to the external pipe 8 at a constant water pressure. Then the clean water flows through the water pipe 6, the water storage plate 7, the docking hose 10 in sequence and enters the water meter, and then flows out through the other external pipe 8 and is collected. When the water flow in the external pipe 8 is stable, the amount of water collected per unit time is measured and compared with the increased reading of the water meter to detect whether the measurement of the water meter is accurate; close the docking hose 10 near the water outlet of the water meter to increase the water pressure in the water meter, and observe the sealing of the water meter. The water storage plate 7 can divert the clean water to different docking hoses 10.

[0034] Furthermore, in this embodiment, the docking hoses 10 are distributed in a circular array on the end surface of the water storage plate 7, each group of clamping plates 9 is composed of a group of elastic metal plates, and the docking hoses 10 are clamped and fixed on the inner side of a group of elastic metal plates.

The setting of the end plate 15 prevents the guide rod 13 from sliding off the movable plate 4, and the setting of the rubber pad 17 can prevent the outer surface of the water meter from being damaged due to excessive extrusion of the clamping plate 16, and can enable the clamping plate 16 to clamp the water meter more stably.

[0036] In order to better control the two movable plates 4 to move closer to or away from each other, in this embodiment, a group of threaded screws 20 are rotatably connected between the two side plates 3, and the two ends of the threaded screw 20 are respectively provided with threads with opposite rotation directions, and the two ends of the threaded screw 20 respectively penetrate the bottom of the two movable plates 4 and are threadedly connected with the two movable plates 4, and sliders 18 are fixed on both sides of the lower surface of the movable plate 4, the threaded screw 20 penetrates the slider 18 and is threadedly connected with the slider 18, one end of the threaded screw 20 penetrates the side plate 3 and is fixed with a sprocket 22, and a chain 23 is sleeved on the outside of the two sprockets 22, and a handwheel 24 is fixedly installed on one side of one of the sprockets 22, and a fixed plate 2 is provided at the center of the upper surface of the operating table 1, and limiting plates 19 are fixed on the opposite sides of the two sliders 18, and limiting grooves 21 are provided on both sides of the fixed plate 2, and the limiting plates 19 are slidably fitted on the inner side of the limiting grooves 21. By rotating the hand wheel 24, the two sprockets 22 can be controlled to rotate synchronously, so that the two threaded screws 20 can rotate synchronously. The threads at the two ends of the threaded screw 20 can drive the sliders 18 on the two movable plates 4 to move closer to or away from each other, thereby achieving the two movable plates 4 to move closer to or away from each other. Through the sliding cooperation between the limit groove 21 and the limit plate 19, the two movable plates 4 can be stably moved horizontally.
