Description

Technical Field

[0001] This utility model relates to the field of gas meter testing, specifically a simulation device for testing the humidity of gas meters. Background Technology

[0002] As a core device for measuring gas consumption, gas meters often operate in environments with varying humidity levels. Excessive humidity can lead to problems such as short circuits in internal circuits and corrosion of mechanical parts, affecting metering accuracy and lifespan. Therefore, during the gas meter manufacturing process, humidity tests must be conducted to simulate various humid environments and verify their tolerance.

[0003] Most gas meter humidity test simulation devices adopt an integrated humidity chamber structure, which creates a humid test environment by spraying water mist or introducing humid air into the chamber. However, during the test, a large amount of water mist will directly adhere to the surface of the gas meter, gradually forming a continuous water film or even water accumulation. This phenomenon will cause obvious problems. Excess water can easily seep into the interior along the gaps in the gas meter casing, which not only deviates from the original intention of simulating the influence of environmental humidity, but may also cause equipment failures caused by non-environmental factors, thereby interfering with the accurate judgment of test results. Therefore, we provide a simulation device for gas meter humidity testing. Utility Model Content

[0016] 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.

[0017] like Figure 1-6 As shown, this utility model provides a technical solution: a simulation device for testing the humidity of a gas meter, including a test chamber 1. The front of the test chamber 1 is hinged to an opening and closing door 2. A handle is installed on the outer surface of the opening and closing door 2. The handle provides convenience for opening the opening and closing door 2, thereby enabling the device to be used normally in the future.

[0018] The outer surface of the test chamber 1 is equipped with an experimental component 3, which includes a water tank 301. The water tank 301 is installed on the left side of the test chamber 1. The water tank 301 can store water, which facilitates the subsequent atomization work.

[0019] A pump 302 is installed on the upper surface of the water tank 301. The input end of the pump 302 is connected to an input pipe 303, and the other end of the input pipe 303 is connected to the outer surface of the water tank 301. The output end of the pump 302 is connected to an output pipe 304. The other end of the output pipe 304 passes through the upper surface of the test chamber 1 and extends into the interior of the test chamber 1. The output end of the output pipe 304 is connected to an atomizing nozzle 305. The pump 302 can extract water, and the atomizing nozzle 305 can spray water in a mist, which is convenient for subsequent experiments on the gas meter. The outer surface of the output pipe 304 is connected to a valve 306, which can control the amount of water sprayed by the atomizing nozzle 305 and can be adjusted according to the actual situation.

[0020] Experimental component 3 also includes a first humidity detector 307 and a partition 308. The first humidity detector 307 is installed on the inner bottom wall of the test chamber 1, and the partition 308 is fixedly connected to the inside of the test chamber 1. The partition 308 can block the flow, which facilitates fine adjustment of humidity in the future and ensures the accuracy of the test.

[0021] A set of flue backflow preventers 309 are installed on the outer surface of the partition 308. Each flue backflow preventer 309 has a connecting fan 310 installed inside. The flue backflow preventer 309 and the connecting fan 310 are designed together to ensure that no backflow occurs when moisture is being transported, thus ensuring that subsequent experiments can be carried out normally.

[0022] Experimental component 3 also includes a second humidity detector 311, which is installed on the inner top wall of the test chamber 1. A control panel 312 is installed on the front of the water tank 301. The second humidity detector 311 can detect humidity, and the detected data will be displayed on the surface of the control panel 312 for easy viewing later.

[0023] Experimental component 3 also includes two sets of connecting frames 313. The connecting frames 313 are installed inside the test chamber 1, and a set of placement plates 314 are installed between the connecting frames 313 by bolts. The placement plates 314 installed by bolts can adjust the spacing between the placement plates 314, thereby adapting to the experimental work of different gas meter models and making it more practical.

[0024] Experimental component 3 also includes a set of round holes 315 on the back of the test chamber 1. Each placement plate 314 is equipped with an exhaust fan 316. Each round hole 315 is sealed with a sealing plug 317. The outer surface of each sealing plug 317 is fixedly connected to a connecting plate 318 by a short rod. The exhaust fan 316 can exhaust moisture and can be adjusted according to the actual situation. The sealing plug 317 can seal the round hole 315, thereby ensuring the accuracy of subsequent experiments.

[0025] In use, first place the gas meter to be tested on the surface of the placement plate 314, then start the pump 302. The input end of the pump 302 starts to draw water from the water tank 301. The water will be sprayed out in a mist from the atomizing nozzle 305 through the output pipe 304. Then the humidity on one side of the test chamber 1 will gradually increase. The first humidity detector 307 can detect the humidity. When the humidity reaches a certain value, the connecting fan 310 is started. The connecting fan 310 delivers the moisture to the other part of the test chamber 1. When the value of the other half reaches the experimental value after being detected by the second humidity detector 311, the flue check valve 309 stops working and the humidity simulation experiment of the gas meter begins.
