Abstract
The utility model relates to a detection device, in particular to an SF6 gas leakage detection device of a long pipe and a short pipe. In the utility model, the output end of an SF6 gas leak detector is connected with the input of a first check valve, the output end of the first check valve is connected with the input end of a sampling pipe of 7 meters, the output end of the sampling pipe of 7 meters is connected with the input end of a second check valve, and the output end of the second check valve is connected with the input end of a probe of an instrument. The utility model has the following advantages that two sampling pipelines with different lengths are adopted, a pipeline of 7 meters is mainly used for the general investigation of a flange face, and a sampling pipeline of 2 meters is mainly used for positioning a point with superstandard leakage. After improvement, the field application is very convenient, the leak detection time is greatly saved, and the working efficiency is enhanced.
Description
Technical field
The utility model relates to a kind of pick-up unit, specifically relates to a kind of long tube, short tube SF
6Gas leak detection apparatus.
Background technology
SF
6Gas leakage detector sampling conduit standard is 1.0 meters, and the instrument reflection time is short, and sensitive.But on-the-spot SF
6The most of height of electrical equipment adopts the sampling conduit of this length more than 5 meters, and appliance requires moves up and down, otherwise instrument probe does not reach the detection position.Instrument deadweight 10kg uses very inconvenient, and dangerous.
Summary of the invention
The purpose of this utility model provides and a kind of long tube is set, two kinds of sampling conduits of short tube detect SF
6Long tube, short tube SF that gas leaks
6Gas leak detection apparatus.
A kind of long tube of the utility model, short tube SF
6Gas leak detection apparatus is achieved by following technical proposals: a kind of long tube of the utility model, short tube SF6 gas leak detection apparatus comprise SF
6Gas leakage detector, first reverse checkvalve, 7 meters sampling pipes, second reverse checkvalve, instrument probe, 2 meters sampling pipes, described SF
6The gas leakage detector output terminal is connected with the input of first reverse checkvalve, and the first reverse checkvalve output terminal is connected with 7 meters sampling pipe input ends, and 7 meters sampling pipe output terminals are connected with the second reverse checkvalve input end, and the second reverse checkvalve output terminal is connected with the instrument probe input end.
A kind of long tube of the utility model, short tube SF
6Gas leak detection apparatus has following beneficial effect compared with prior art: the utility model has adopted the sampling conduit of two kinds of different lengths according to actual conditions, a kind of length 7 mitron roads, a kind of length 2 mitron roads.7 mitron roads are mainly used in the flange face generaI investigation, and 2 meters sampling conduits are mainly used in and leak the location that exceeds standard a little.Sampling conduit to two kinds of different lengths has carried out instrument response time and sensitivity test respectively before formal the use.7 meters sampling conduit test durations have response from sampling to instrument, and 30 seconds time, field requirement continues sampling and finished in 1 minute.2 meters 15 seconds sampling conduit times, field requirement continues sampling and finished in 30 seconds.After improving, rig-site utilization is very convenient, has saved the leak detection time greatly, has improved work efficiency.
