Abstract

The invention relates to a single-component continuous leak detection system and a leak detection method thereof. Single-component continuous leak detection system includes sampling detection probe, connector, three-way solenoid valve, flow sensor, buffer tank, sampling gas pump and backflushing gas pump and main control circuit, sampling detection probe, connector, three-way solenoid valve, flow rate The sensor, the buffer tank and the sampling air pump are connected in sequence to form a measuring air circuit, and the backflushing air pump, the three-way solenoid valve, the connector and the sampling detection probe form the backflushing cleaning air circuit. The signal output end of the sampling detection probe is connected with the main control circuit through the connector, and the flow sensor, the three-way solenoid valve, the sampling air pump and the backflushing air pump are respectively connected with the main control circuit. The invention utilizes the measuring gas path and the backflushing cleaning gas path, and automatically judges the opening of the backflushing cleaning gas path through the concentration and noise, and has strong environmental anti-interference ability. By moving the handle-type sampling detection probe, the gas-sensitive film is used to measure the hydrogen leakage concentration, with high sensitivity and fast response speed.

Description

technical field [0001] The invention relates to a gas leak detection device, in particular to a single-component continuous leak detection system with high detection sensitivity and a leak detection method thereof. Background technique [0002] With the development of manufacturing technology, the performance requirements of various precision devices such as engines, pressure vessels, valves, pipelines, etc. are getting higher and higher, and the airtightness of devices is one of the key factors affecting product performance and life. Therefore, in the field of manufacturing and inspection and maintenance, leak detection technology is very critical. [0003] Leak detection technology is mainly divided into sniffing type and diffusion type. Due to the slow response speed and low efficiency of the diffusion type leak detection method, it is rarely used in industrial automation production. The sniffing leak detection technology can timely and accurately detect the content of s...
