Description

Technical Field

[0001] The utility model belongs to the technical field of elliptical gears, and particularly relates to an elliptical gear flowmeter for measuring pure water. Background Art

[0002] An elliptical gear flowmeter is a flowmeter based on the principle of gear transmission. Specifically, when liquid enters the elliptical gear flowmeter, the liquid pushes the elliptical gear to rotate, and the flowmeter measurement is realized through the rotating elliptical gear.

[0003] However, the accuracy of the flowmeter measurement is greatly affected by the bubbles in the measurement medium. That is, in the case where the fluid medium is prone to contain bubbles, especially when the amount of bubbles is large, under the influence of the bubbles, the accuracy of the flowmeter measurement is very low.

[0004] Specifically, in the actual working process, when the flowmeter is used to measure the water flow rate, during the measurement process of the flowmeter, due to the large amount of bubbles easily contained in the water, the accuracy of the flowmeter measurement is very low. Therefore, in the actual working process, in order to increase the accuracy of the flowmeter, a relatively conventional method at present is to install structures such as a filter net in the pipeline, which can achieve filtration and reduce the bubbles in the water. Specifically, when the bubbles pass through the filter holes of the filter net, the bubbles with a large bubble volume are easily broken.

[0005] However, in the actual working process, after being filtered by the filter net, the water body still contains a large amount of bubbles, especially a large amount of small bubbles. The small bubbles are more likely to pass through the filter net and then enter the flowmeter, resulting in the flowmeter being unable to accurately measure the fluid. Summary of the Utility Model

[0006] Based on the above background, the purpose of the utility model is to provide an elliptical gear flowmeter for measuring pure water.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0037] Embodiment 1

[0038] As Figures 1-5 shown, an oval gear flowmeter for measuring pure water includes a gear flowmeter body 1. The gear flowmeter body 1 is a conventional oval gear flowmeter disclosed in the prior art, and its main structure includes a housing, two oval gears installed in the housing, and a meter installed on the housing. In order to solve the problem that air bubbles in water affect the measurement accuracy of the flowmeter, the following improvements are made:

[0039] The liquid inlet end 11 of the gear flowmeter body 1 is assembled and connected with an air defoaming water inlet pipe 2 (specifically, in accordance with the existing conventional method, the liquid inlet end of the gear flowmeter body 1 is connected with an elbow pipe through a flange, and the elbow pipe is not shown in the figure. The elbow pipe is connected to a straight air defoaming water inlet pipe 2), and an air defoaming mechanism is assembled and connected in the air defoaming water inlet pipe 2.

[0040] Specifically, the air defoaming mechanism is used to eliminate the air bubbles in the air defoaming water inlet pipe 2.

[0041] Specifically, the air defoaming mechanism includes liquid passing plates 31 arranged at intervals on both sides (the liquid passing plates 31 are fixedly installed in the lumen of the air defoaming water inlet pipe 2), and a number of liquid passing through holes 311 are opened on the liquid passing plates 31. A metal filter screen (not shown in the figure) is installed on the liquid passing through holes 311 in accordance with the existing conventional method to achieve filtration.

[0042] At the same time, an air defoaming component is rotatably connected between the liquid passing plates 31. Specifically, the air defoaming component includes a long rotating rod 32. Correspondingly, an installation hole is opened at the central part of the liquid passing plate 31, and a bearing is installed in the installation hole. The inner ring of the bearing is fixedly installed with the long rotating rod 32.

[0043] At both ends of the long rotating rod 32, a number of defoaming and puncturing components 34 are respectively assembled and connected. With the cooperation of the defoaming and puncturing components 34 at both ends, the bubbles are fully punctured. Specifically, the fluid carrying bubbles passes through the defoaming and puncturing components 34 arranged layer by layer to puncture the bubbles.

[0044] Specifically, the defoaming and puncturing component 34 includes an annular rotating rod 341 installed on the long rotating rod 32 (the specific fixing method is: on the inner side wall of the annular rotating rod 341, two mounting seats are fixedly connected at an interval of 180 degrees, and a fastening screw 3411 fastened on the long rotating rod 32 is threadedly connected to the mounting seat), and a number of bubble-breaking balls 343 are fixedly connected to the outer side wall of the annular rotating rod 341. Specifically, the bubble-breaking balls 343 are installed on the outer side wall of the annular rotating rod 341 through connecting rods 342.

[0045] At the same time, a number of puncturing needle rods 344 are fixedly connected to the bubble-breaking balls 343.

[0046] During the working process, the rotating long rotating rod 32 drives the annular rotating rod 341 to rotate. During the rotation process, first, the bubble-breaking balls 343 continuously impact the bubbles in the fluid to break the bubbles. During the rotation process, under the action of the densely distributed puncturing needle rods 344, a large number of bubbles of different volumes are completely punctured after impact.

[0047] The above-mentioned long rotating rod 32, annular rotating rod 341, and bubble-breaking balls 343 are all made of lightweight plastic materials.

[0048] In order to realize the automatic rotation through the fluid, an impeller member 33 is fixedly assembled and connected to the end of the long rotating rod 32, and the impeller member 33 faces the water inlet end of the defoaming water inlet pipe 2. Specifically, the impeller member 33 includes a ball seat fixedly connected to the right end part of the long rotating rod 32, and a number of blades are fixedly connected to the ball seat.

[0049] During the working process, under the action of the driving blades of the fluid, at this time, the long rotating rod 32 drives the above-mentioned defoaming and puncturing components 34 to puncture the bubbles.

[0050] Embodiment 2

[0051] As Figures 1-5 shown, on the basis of the structure of Embodiment 1 in this embodiment, in order to further remove the bubbles carried in the fluid, a spiral flow disturbing mechanism is fixedly connected to the annular rotating rod 341. Specifically, the spiral flow disturbing mechanism is located at the central part of the annular rotating rod 341. The specific structure of the spiral flow disturbing mechanism is as follows:

[0052] The spiral flow disturbing mechanism includes a first spiral flow disturbing vane 35 and a second spiral flow disturbing vane 36 arranged at intervals. The spiral directions of the first spiral flow disturbing vane 35 and the second spiral flow disturbing vane 36 are set in opposite directions.

[0053] During the working process, under the action of the first spiral spoiler 35 and the second spiral spoiler 36 with different spiral rotation directions on both sides, the flow velocity of the fluid (the velocity has magnitude and direction) is disturbed. When the flow velocity is disturbed, the pressure balance between the bubbles and the fluid in the water body is broken. At this time, the bubbles are more easily eliminated.

[0054] Embodiment 3

[0055] As Figures 1-5 shown, on the basis of the structure of Embodiment 2, an exhaust mechanism is connected to the top of the defoaming water inlet pipe 2 in this embodiment. Specifically, the bubbles in the water contain gas. During the process of piercing the bubbles, the gas in the pipeline is exhausted through the exhaust mechanism, and the bubbles in the water are further removed through exhaust.

[0056] Specifically, the exhaust mechanism includes an exhaust pipe 41 connected to the defoaming water inlet pipe 2 (a valve is installed on the exhaust pipe 41). The top of the exhaust pipe 41 is connected to a buffer ball 4 (during the exhaust process, the overflow water is cached by the buffer ball 4). The top of the buffer ball 4 is connected to an air release pipe 42, and a valve is assembled and connected to the air release pipe 42. Opening the valve on the air release pipe 42 realizes the removal of bubbles.

[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present invention should also fall within the protection scope of the present invention.
