Multifunctional gas quantitative leak detector

Abstract

The invention relates to a multifunctional gas quantitative leak detector which comprises a leak detector body, a probe and an electric control unit. An inlet filter seat is arranged on the top of the leak detector body, a power chamber is arranged inside the lower end of the leak detector body, and a flow chamber is positioned on the upper portion of the power chamber; a silencing plate is arranged at the bottom of the inlet filter seat, a check valve is arranged in the center of the top of the inlet filter seat, and a gas pipeline is connected with the inlet filter seat by the check valve; a pressure sensor is further arranged between the top of the inlet filter seat and the check valve; the probe comprises a probe shell and a fan; the probe shell is fixedly connected to the tail end of the gas pipeline; the fan is arranged in a gas chamber of the probe shell; the electric control unit is arranged inside the leak detector body and comprises a controller module, a power switch module, a button module, a gas sensing module, a detection module, a gas alarm module, an indicator lamp module and a power management module. The multifunctional gas quantitative leak detector has the advantages that the multifunctional gas quantitative leak detector is easy and convenient to operate and high in leak detection accuracy and detection efficiency and is small, the flow of to-be-detected gas can be voluntarily adjusted, and the gas can be quantitatively detected.

Description

technical field [0001] The invention relates to a gas leak detection device, in particular to a multifunctional gas quantitative leak detector. Background technique [0002] The gas leak detector adopts the latest electronic circuit and is specially designed to meet the current and future detection of SF6 gas leakage in various switches, fully enclosed combined electrical appliances and other devices. The instrument test is a qualitative analysis. The operator simply flips a switch and the leak detector is programmed to search for multiple gases in no time. When the leaking gas is close to the leak detector, an alarm similar to a computer will give an alarm signal, and the alarm speed and frequency will increase with the increase of the leakage. In polluted atmospheres, the leak detector recalibrates extremely quickly to prevent false readings. Built-in special miniature high-efficiency pump helps to reduce leakage response time.

Problems solved by technology

[0003] In the prior art, the leak detector does not use modules with high integration and low energy consumption, but uses a large number of electronic components, resulting in a large volume and high quality of the leak detector, which is not conducive to the carrying of the test personnel and cannot realize the gas flow rate. The setting, the use range is small, the gas is not easy to enter the pipeline, and the gas flow rate entering the pipeline is large, the fluctuation is large, and there is an impact on the pipeline, which greatly reduces the service life of the pipeline. When using it, the mining industry cannot realize the detection of different gases. The accuracy and efficiency of leak detection are low, and it requires a lot of human and material resources, which is not conducive to mass promotion and use
