Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to a single-flow velocity water meter with a rectifier. Background Technology

[0002] A water meter is an instrument used to measure and record the amount of water flowing through a pipe. It is typically installed on water supply pipes and accurately measures water consumption by monitoring the time and speed of water flow. Water meters are widely used in public water supply systems for purposes such as billing, monitoring water consumption, and detecting leaks. Currently, in existing water meters, the lower casing is used for both water inlet and outlet. However, during the water flow in and out, water turbulence can easily form inside the lower casing, leading to unstable water flow and affecting the meter's accuracy. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a single-flow velocity water meter with a rectifier, which improves the flow stability of water within the rectifier housing and enhances the detection accuracy of the water meter.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a single-flow velocity water meter with a rectifier, comprising an upper housing and a rectifier housing, the upper housing being fixedly disposed at the upper end of the rectifier housing, a meter body being disposed inside the upper housing, an inlet pipe and an outlet pipe being coaxially connected to both ends of the rectifier housing, a rectifier device being disposed inside the rectifier housing, the rectifier device comprising an end cover and a rectifier base, the end cover being disposed at the upper end of the rectifier base, an inlet port and an outlet port being respectively opened on both sides of the rectifier base, the inlet port being connected to the inlet pipe, the outlet port being connected to the outlet pipe, a water dividing baffle being disposed at the inlet port, a rectifier cavity being disposed inside the rectifier base, and an impeller being rotatably connected to the center of the rectifier cavity; Water flows in from the inlet port, is divided into two streams by the water divider, and then impacts the impeller to drive it to rotate before flowing out from the outlet port.

[0005] Furthermore, the water inlet port is provided with a first inclined surface and a second inclined surface, the first inclined surface and the second inclined surface are inclined in the same direction, the water outlet port is provided with a third inclined surface and a fourth inclined surface, the third inclined surface and the fourth inclined surface are inclined in the same direction, the water inlet port and the water outlet port are inclined in opposite directions, and the water dividing baffle is inclined in the same direction as the water inlet port.

[0006] Furthermore, the relative angle between the first inclined plane and the second inclined plane is 3.88°, the relative angle between the third inclined plane and the fourth inclined plane is 20.15°, and the relative angle between the third inclined plane and the water-dividing baffle is 11.42°.

[0007] Furthermore, it also includes a flow regulating rod, the lower end of which passes through the end cap and extends into the water inlet port.

[0008] Furthermore, the flow regulating rod includes an regulating end and an regulating rod portion. The regulating rod portion is fixed to the lower end of the regulating end. An regulating groove is provided through the end cap. The regulating end is rotatably disposed in the regulating groove. The regulating rod portion is flat in shape.

[0009] Furthermore, a filter device is provided inside the inlet of the water inlet pipe. The filter device includes a filter head and a filter screen. The filter head is fixedly embedded inside the inlet of the water inlet pipe, and the filter screen is disposed inside the filter head.

[0010] The beneficial effects of this utility model are: This invention improves the stability of water flow within the rectifier housing by incorporating a rectifier device inside the housing. Water enters through the inlet port of the rectifier base, driving an impeller to rotate within the rectifier cavity, creating a vortex that ultimately flows out from the outlet port. This effectively enhances the stability of water flow within the rectifier housing, preventing turbulence and sloshing, and thus improving the accuracy of the water meter. Furthermore, by installing a water-dividing baffle at the inlet port, the water flow is diverted and its velocity adjusted during the inlet process, ensuring consistent flow velocities between the inlet and outlet ports, further enhancing the stability of water flow within the rectifier housing.

Detailed Implementation

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0014] like Figure 1 and Figure 2 As shown, a single-flow velocity water meter with a rectifier 3 includes an upper housing 1 and a rectifier housing 2. The upper housing 1 is fixedly installed on the upper end of the rectifier housing 2. A meter body is provided inside the upper housing 1. The two ends of the rectifier housing 2 are connected to a coaxially arranged inlet pipe 8 and outlet pipe 9. The rectifier housing 2 is provided with a rectifier 3. The rectifier 3 includes an end cover 4 and a rectifier base 5. The end cover 4 is installed on the upper end of the rectifier base 5. An inlet port 6 and an outlet port 7 are respectively opened on both sides of the rectifier base 5. The inlet port 6 is connected to the inlet pipe 8, and the outlet port 7 is connected to the outlet pipe 9. A water divider 11 is provided at the inlet port 6. A rectifier cavity is provided inside the rectifier base 5. An impeller 10 is rotatably connected to the center of the rectifier cavity. Water flows in from the inlet port 6, is divided into two streams by the water divider 11, and then impacts the impeller 10 to drive the impeller 10 to rotate, and flows out from the outlet port 7.

[0015] Specifically, in this embodiment, the end cap 4 is used to isolate the meter body inside the upper housing 1 from the rectifier 3. Furthermore, the upper end of the end cap 4 may be provided with a sealing ring to achieve a waterproof seal between the meter body and the rectifier 3.

[0016] This technical solution improves the stability of water flow within the rectifier housing 2 by installing a rectifier device 3 inside the rectifier housing 2, allowing water to enter through the inlet port 6 of the rectifier base 5, driving the impeller 10 to rotate within the rectifier cavity, forming a vortex, and finally flowing out from the outlet port 7. This effectively improves the stability of water flow within the rectifier housing 2, preventing water turbulence and sloshing within the rectifier housing 2, thereby improving the detection accuracy of the water meter. At the same time, by installing a water-dividing baffle 11 at the inlet port 6, the water flow is diverted and its velocity is adjusted during the water entry process, ensuring that the water flow velocity at the inlet port 6 and the outlet port 7 remains consistent, further improving the stability of water flow within the rectifier housing 2.

[0017] As the water flow drives the impeller 10 to rotate, the meter body measures the rotational speed of the impeller 10 and calculates the water flow velocity based on the rotational speed of the impeller 10, thus completing the function of the water meter.

[0018] Preferably, the water inlet port 6 is provided with a first inclined surface and a second inclined surface, the first inclined surface and the second inclined surface are inclined in the same direction, the water outlet port 7 is provided with a third inclined surface and a fourth inclined surface, the third inclined surface and the fourth inclined surface are inclined in the same direction, the water inlet port 6 and the water outlet port 7 are inclined in opposite directions, and the water dividing baffle 11 is inclined in the same direction as the water inlet port 6.

[0019] Specifically, in this embodiment, by setting the inlet port 6 and outlet port 7 in opposite directions, it is easier to form a rotating vortex when the water flows in and out, which can better drive the impeller 10 and further improve the flow stability of the water in the rectifier housing 2.

[0020] Preferably, the relative angle between the first inclined plane and the second inclined plane is 3.88°, the relative angle between the third inclined plane and the fourth inclined plane is 20.15°, and the relative angle between the third inclined plane and the water-dividing baffle 11 is 11.42°.

[0021] Specifically, in this embodiment, by setting the aforementioned relative angles, the water flow can enter and exit the rectifier cavity in the most stable state, further ensuring the flow stability of the water flow within the rectifier housing 2.

[0022] Preferably, it also includes a flow regulating rod 12, the lower end of which passes through the end cover 4 and extends into the water inlet port 6.

[0023] Preferred, such as Figure 3 As shown, the flow regulating rod 12 includes an regulating end 121 and an regulating rod portion 122. The regulating rod portion 122 is fixed to the lower end of the regulating end 121. An regulating groove is provided through the end cap 4. The regulating end 121 is rotatably disposed in the regulating groove. The regulating rod portion 122 is flat in shape.

[0024] Specifically, in this embodiment, by setting a flow regulating rod 12, the regulating end 121 is rotated in the regulating groove, thereby driving the regulating rod part 122 to rotate, thus realizing the real-time adjustment of the inlet flow at the water inlet port 6.

[0025] Preferably, a filter device 13 is provided inside the inlet of the water inlet pipe 8, such as... Figure 4 As shown, the filtration device 13 includes a filter head 131 and a filter screen 132. The filter head 131 is fixedly embedded inside the inlet of the water inlet pipe 8, and the filter screen 132 is disposed inside the filter head 131.

[0026] Specifically, in this embodiment, by setting a filter head 131 and a filter screen 132 in the water inlet pipe 8, the impurities in the water inlet are effectively filtered, preventing the impurities from entering the rectifier housing 2 and damaging the impeller 10, thereby improving the durability of the rectifier device 3.

All technical solutions falling within the scope of this utility model's concept are within its protection scope.
