Gas meter core capacity and core inner leakage detection device

Abstract

The invention discloses a gas meter core capacity and core inner leakage detection device. The device comprises an air source. The air source is connected with a first air-intake pipe. The other end of the first air-intake pipe is connected with an electronic flow meter. The other end of the electronic flow meter is connected with a second air-intake pipe. The device further comprises a sealing cover plate. The sealing cover plate is connected with a compressing device. The sealing cover plate is provided with more than four air-intake adapters. When the sealing cover plate is placed above the core air inlet and outlet of a gas meter, at least one air-intake adapter is arranged corresponding to the upper part of each capacity cavity of a core. During the entire process, each solenoid valve and the movements of all the other parts are controlled by a PLC, so that the automatic detection effect is realized. The capacitance detection of one core and four capacity cavities can be completed within about only two minutes, and the detection accuracy thereof is up to 99.8%. Therefore, the application and industrialized production requirements can be fully met. By means of the device, whether the capacity of a core capacity cavity is questioned or not can be quickly detected in the factory industrialization field. As a result, the device ensures the quick production of gas meters.

Description

technical field [0001] The invention relates to a device for detecting core capacity and core internal leakage, in particular to a gas meter core capacity and core internal leakage detection device. Background technique [0002] As a metering instrument for measuring gas consumption, gas meters are closely related to people's lives. The main factors that cause measurement errors in the gas meter are the following factors: the capacity error of the movement capacity cavity, the transmission of the valve cover and the connecting rod, the gear transmission of the gas meter, and the counting problem of the gas meter. If a counting error is found during the production or use of a gas meter, it is mainly caused by the above reasons. But how to determine which component has the problem is more difficult. For gas meter manufacturers, after the gas meter is assembled, it needs to pass a comprehensive performance test. If the comprehensive performance test fails, it needs to analyze...

But how to judge which component has the problem is more difficult

For gas meter manufacturers, after the gas meter is assembled, it needs to pass a comprehensive performance test. If the comprehensive performance test fails, it needs to analyze which part of the problem is the problem, so as to find a solution. However, there are currently no such products on the market. A unilateral detection method and detection device for the capacity error of the movement capacity cavity, the transmission problem of the valve cover and the connecting rod, the transmission problem of the gas meter gear, and the counting problem of the gas meter

As a result, it is extremely difficult to analyze the cause of the measurement error of the problematic gas meter, so that the enterprise can only scrap the whole machine as the cost, resulting in greater waste, increasing the production cost, and restricting the production efficiency of the enterprise
