Diaphragm gas meter salt fog test device and use method thereof

Abstract

The invention discloses a diaphragm gas meter salt fog test device and a use method thereof, and belongs to the technical field of gas meter quality detection. The diaphragm gas meter salt fog test device comprises a test box and positioning components, the positioning components are used for positioning a gas meter arranged in the test box, a salt fog sprayer is arranged in the test box, the positioning components are arranged on the front side and the rear side of the salt fog sprayer and include first positioning components and second positioning components, the first positioning componentsare used for adjusting and positioning in the width direction of the gas meter, and the second positioning components are used for adjusting and positioning in the length direction of the gas meter.The diaphragm gas meter salt fog test device has the advantages that that the salt fog test device is simple in overall structure, a plurality of gas meters can be stably, conveniently and fixedly positioned, the distance between one gas meter and the center of the salt fog sprayer is equal to that between another gas meter and the center of the salt fog sprayer, so that the gas meters cannot displace when external force is applied onto the gas meters and uniformly and stably receive spray volume, and the device is applicable to positioning tests of the gas meters with different types.

Description

technical field [0001] The invention relates to the technical field of gas meter quality detection, in particular to a salt spray test device for a membrane gas meter and a use method thereof. Background technique [0002] The quality inspection of gas meters includes the detection of resistance to environmental conditions, including whether the performance of gas meters is affected under low temperature, high temperature, constant humidity, salt spray and vibration test conditions. According to GB / T 16411-1996 "General Test Methods for Household Gas Appliances", the requirement for the salt spray test is that after the test period is 24 hours, all the sockets should be in contact with the gas meter outlet. Good, and meet the requirements, so the gas meter needs to meet the anti-salt spray performance. [0003] For the currently used salt spray test chamber, there is no internal part for positioning the gas meter, but it is manually placed inside the test chamber. Since the...

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides a salt spray test device for a membrane gas meter, which mainly solves the problem that the existing salt spray test chamber cannot locate the gas meter placed inside, and the gas meter is easily displaced by an external force. , thus affecting the results of the salt spray test, the purpose is to design a salt spray test device that can fix multiple gas meters at the same distance from the center of the salt spray nozzle, so that the gas meters will not move after being subjected to external force position, which ensures the uniform and stable amount of spray received by the gas meter, and is suitable for positioning tests of different types of gas meters
