Description

A water meter detection and calibration device Technical field

[0001] The utility model relates to the technical field of water meter calibration, and specifically relates to a water meter detection and calibration device. Background technique

[0002] A water meter is an instrument that measures the amount of water by measuring the cumulative flow of water passing through it. After the production of the water meter, in order to calibrate whether the measurement of the water meter is accurate, calibration equipment needs to be used to calibrate it to ensure its qualified quality.

[0003] The Chinese patent provides a water meter detection and calibration device, with the publication number CN222544798U, including a bottom plate, and a detection mechanism is provided on the bottom plate; the detection mechanism includes two detection boxes, a liquid level gauge is installed on the side of the detection box, and the liquid level gauge is used to measure the liquid volume in the detection box, and a support component is provided on the top of the bottom plate.

[0004] The above device, through the bottom plate and the detection box, is beneficial to improving the batch calibration efficiency of the water meter. By setting a "zigzag" transparent water pipe, a hard pipe and a water pump, it is convenient to drain the water in one detection box into the water meter, and it is convenient to observe whether there are bubbles in the transparent water pipe, and make the bubbles in the transparent water pipe stay at the highest point to prevent the bubbles from entering the water meter;

[0005] However, although it can be quickly replaced, the water delivery structure is relatively single, and it can only deliver water flow at a single temperature into the water meter, making it difficult to test the detection of water flow at different temperatures by the water meter, with poor detection effects. And although bubbles can be eliminated during detection, in actual use, the water flow in the water pipe may contain bubbles, and it is difficult to completely eliminate them for detection and compare with the detection data during its normal use. Summary of the invention

[0006] The purpose of the utility model is to provide a water meter detection and calibration device, which can effectively solve the problems in the background technique.

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

[0008] A water meter detection and calibration device includes a detection table, a temperature control water storage tank is installed at a position close to one side of the top of the detection table, a detection component is provided at a position close to the other side of the top of the detection table, and the detection component has a number of water delivery pipes one and water delivery pipes two that match the number of temperature control water storage tanks;

[0009] The water inlet ends of each water delivery pipe 1 are respectively connected to the water outlet of each temperature-controlled water storage tank. The water delivery pipe 2 is connected to the end of the water delivery pipe 1 far from the temperature-controlled water storage tank. A connecting cone pipe 1 is connected to the end of the water delivery pipe 2 far from the water delivery pipe 1. A support plate is installed at a position near one side of the top of the detection table. A connecting cone pipe 2 is slidably installed on the top of the support plate through a sliding frame. The number of the connecting cone pipes 2 is adaptively matched with that of the connecting cone pipes 1, and a water meter body is arranged between the connecting cone pipe 2 and the connecting cone pipe 1. A plurality of electric telescopic rods are installed on the top of the support plate through a mounting plate. The end of the push rod of the electric telescopic rod is connected to the upper position of the front end of the sliding frame, and a sliding rod is connected to the lower position of the front end of the sliding frame. The sliding rod is slidably connected to the electric telescopic rod.

[0010] Preferably, a corrugated hose is connected to the end of the connecting cone pipe 2 far from the connecting cone pipe 1, and a drain pipe is connected to the end of the corrugated hose far from the connecting cone pipe 2.

[0011] Preferably, the centers of the connecting cone pipe 2, the connecting cone pipe 1, the water meter body, and the corrugated hose are on the same straight line, and the outer circles of the connecting cone pipe 1 and the connecting cone pipe 2 are coated with sealing rubber sleeves.

[0012] Preferably, a water outlet solenoid valve is arranged at the connection between the water delivery pipe 1 and the temperature-controlled water storage tank, and a check valve 2 is arranged at the connection between the water delivery pipe 1 and the water delivery pipe 2.

[0013] Preferably, a transparent water pipe is fixedly installed at a position near one side of the outer circle of the water delivery pipe 2. The transparent water pipe is arranged in a "U" shape. A diversion solenoid valve is arranged at the connection between the end of the transparent water pipe close to the temperature-controlled water storage tank and the water delivery pipe 2, and a check valve 1 is arranged at the connection between the other end of the transparent water pipe and the water delivery pipe 2.

[0014] Preferably, the outer circles of the water delivery pipe 1, the water delivery pipe 2, and the drain pipe are all coated with heat-insulating and heat-preserving sleeves, and a cut-off solenoid valve is arranged at a position on the outer circle of the water delivery pipe 2 close to the diversion solenoid valve.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] By arranging the detection component in cooperation with the temperature-controlled water storage tank, when detecting the water meter body, different temperature water flows stored in different temperature-controlled water storage tanks can be sequentially delivered to the water meter body to check the detection situation of the water meter body for water flows with different temperatures, so as to improve the detection accuracy. Moreover, there are multiple connecting cone pipes 1 and water meter bodies, and through an alternating detection method, the inspection quantity of the water meter body can be increased, which is convenient for quick replacement and improves the production efficiency.

[0017] By setting up a flow-guiding solenoid valve, a shut-off solenoid valve, a transparent water pipe, and a water supply pipe to work together, the water inlet path can be adjusted during water intake. When water is supplied through the transparent water pipe, air bubbles stay at the highest point, preventing them from entering the water meter body and affecting the water meter's detection effect. When the transparent water pipe is not used, water that may contain air bubbles will flow directly into the water meter body for subsequent data verification and comparison, thus improving the detection effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Referring to Figures 1-3, a water meter testing and calibration device includes a testing platform 1. A temperature-controlled water storage tank 2 is installed on one side of the top of the testing platform 1, and a testing component 3 is set on the other side of the top of the testing platform 1. The testing component 3 has a number of water supply pipes 4 and 6 that match the number of temperature-controlled water storage tanks 2.

[0025] Referring to Figures 2 and 3, it is further seen that the inlet end of each water supply pipe 4 is connected to the outlet of each temperature-controlled water storage tank 2. Water supply pipe 6 is connected to the end of water supply pipe 4 furthest from the temperature-controlled water storage tank 2. A connecting cone pipe 13 is connected to the end of water supply pipe 6 furthest from water supply pipe 4. A support plate 12 is installed on one side of the top of the testing platform 1. A connecting cone pipe 15 is slidably installed on the top of the support plate 12 via a sliding frame 19. The number of connecting cone pipes 15 is adapted to match the number of connecting cone pipes 13. A water meter body 14 is provided between the connecting cone pipes 15 and the connecting cone pipes 13. The top of the support plate 12... Several electric telescopic rods 18 are installed on the mounting plate. The push rod end of the electric telescopic rod 18 is connected to the upper front end of the sliding frame 19, and a sliding rod is connected to the lower front end of the sliding frame 19. The sliding rod and the electric telescopic rod 18 are slidably connected. A corrugated hose 17 is connected to the end of the connecting cone pipe 2 15 away from the connecting cone pipe 13, and a drain pipe 16 is connected to the end of the corrugated hose 17 away from the connecting cone pipe 2 15. The center points of the connecting cone pipe 2 15, the connecting cone pipe 13, the water meter body 14, and the corrugated hose 17 are on the same straight line. The outer rings of the connecting cone pipe 13 and the connecting cone pipe 2 15 are covered with sealing sleeves.

[0026] Specifically, by controlling the retraction of the push rod of the electric telescopic rod 18, the second connecting cone tube 15 can be moved away from the first connecting cone tube 13. Then, the water meter body 14 can be placed between the first connecting cone tube 13 and the second connecting cone tube 15. Afterwards, the push rod of the electric telescopic rod 18 can be extended to control the second connecting cone tube 15 and the first connecting cone tube 13 to be inserted into the inlet and outlet of the water meter body 14, so that a fixed amount of water is delivered to the water meter body 14. The water meter body 14 can then detect the flow rate of the passing water, thereby verifying whether it is qualified. When the data displayed at 14 points is consistent with the water flow or within the allowable error, the water meter body 14 is of qualified production quality. During calibration, since different connecting cone pipes 13 are connected to different temperature-controlled water tanks 2 through water supply pipes 6 and 4, and the water flow temperature stored in each temperature-controlled water tank 2 is different, during testing, the flow guiding solenoid valve 8 can be connected to different connecting cone pipes 13 and 15 in sequence to test the detection effect of the flow guiding solenoid valve 8 on water flow of different temperatures. At the same time, multiple stations are set up to conduct inspection and comparison, thereby improving the detection efficiency.

[0027] Example 2

[0028] Referring to FIG. 2 and based on the first embodiment, it is further obtained that a water outlet solenoid valve 5 is provided at the connection between the first water delivery pipe 4 and the temperature-controlled water storage tank 2, a check valve II 11 is provided at the connection between the first water delivery pipe 4 and the second water delivery pipe 6, a transparent water pipe 7 is fixedly installed on the outer ring of the second water delivery pipe 6 at a position close to one side, the transparent water pipe 7 is arranged in a "Ji" shape, a diversion solenoid valve 8 is provided at the connection between one end of the transparent water pipe 7 close to the temperature-controlled water storage tank 2 and the second water delivery pipe 6, a check valve I 10 is provided at the connection between the other end of the transparent water pipe 7 and the second water delivery pipe 6, heat-insulating jackets are coated on the outer rings of the first water delivery pipe 4, the second water delivery pipe 6 and the drain pipe 16, and a cut-off solenoid valve 9 is provided on the outer ring of the second water delivery pipe 6 and at a position close to the diversion solenoid valve 8.

[0029] Specifically, by opening the water outlet solenoid valve 5 and the diversion solenoid valve 8 and closing the cut-off solenoid valve 9, the water flow at the first water delivery pipe 4 can be guided into the transparent water pipe 7 and then conveyed to the second water delivery pipe 6 again through the transparent water pipe 7. Subsequently, the water flow is conveyed to the water meter body 14 along the original path. Through this step, the water inlet path can be adjusted. When using the transparent water pipe 7 for water delivery, the air bubbles stay at the highest position, preventing the air bubbles from entering the water meter body 14 and reducing the interference to the detection effect of the water meter body 14. Through the alternate inspection method, the detection effects of the water meter body 14 on the bubble-free water flow and the water flow with bubbles can be calibrated, so as to compare and verify the data subsequently and improve the detection effect.

[0030] During the actual operation process, corresponding external water pumps are installed on each pipeline, which will not be elaborated here. During the detection, by controlling the push rod of the electric telescopic rod 18 to retract, the connecting cone pipe II 15 can be driven away from the connecting cone pipe I 13. Then, the operator can place the water meter body 14 between the connecting cone pipe I 13 and the connecting cone pipe II 15. Subsequently, the push rod of the electric telescopic rod 18 can be controlled to extend to control the connecting cone pipe II 15 and the connecting cone pipe I 13 to be inserted into the water inlet and outlet of the water meter body 14, so as to convey a certain amount of water flow to the water meter body 14. The water meter body 14 can detect the water flow rate passing through it, so as to verify whether it is qualified. That is, when the data displayed at the water meter body 14 is consistent with the water throughput or within the allowable error range, the production quality of the water meter body 14 is qualified;

[0031] And during the calibration, because different connecting cone pipes I 13 are connected to different temperature-controlled water storage tanks 2 through the second water delivery pipe 6 and the first water delivery pipe 4, and the water flow temperatures stored in each temperature-controlled water storage tank 2 are different. During the detection, the diversion solenoid valve 8 can be successively connected to different connecting cone pipes I 13 and connecting cone pipes II 15 to check the detection effect of the diversion solenoid valve 8 on water flows at different temperatures;

[0032] Multiple workstations are set up at the same time to conduct inspection and comparison, improve testing efficiency, and the water flows out from the drain pipe 16. At this time, the drain pipe 16 can be connected to the external circulating water pump so that the water after testing can be transported to the corresponding temperature-controlled water storage tank 2.

[0033] By opening the flow guiding solenoid valve 8 and closing the shut-off solenoid valve 9, the water flow at point 4 of the first water supply pipe can be guided into the transparent water pipe 7, and then transported again to the second water supply pipe 6 through the transparent water pipe 7. The subsequent water flow is transported to the water meter body 14 along the original path. This step can be used to adjust the water inlet path.

[0034] Furthermore, when using the transparent water pipe 7 to transport water, the air bubbles stay at the highest point, preventing them from entering the water meter body 14 and reducing interference with the detection effect of the water meter body 14. By alternating the test method, the detection effect of the water meter body 14 on water flow without air bubbles and water flow with air bubbles can be verified, so that the data can be compared and verified in the future to improve the detection effect.

[0035] Furthermore, the display and control components and modules used in the aforementioned flow guiding solenoid valve 8, shut-off solenoid valve 9, water outlet solenoid valve 5, temperature-controlled water storage tank 2, and electric telescopic rod 18 are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve improvements to the software and power supply.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
