Description
Technical field
The utility model relates to the apparatus structure technical field that the power equipment to filling SF6 gas carries out gas sample in test link.
Background technology
SF6 gas is the inert gas in the widely used arc extinguishing insulation of power industry.The power equipment that is filled with SF6 gas needs to carry out test verification by some cycles in operational process.But traditional sampling process need to connect multiple joint and multiple management, because connecting link is more, tend to cause the truly situation of gas in reflection equipment of got SF6 gas, said sampling is defective in the industry.In addition, have part to be filled with the power equipment of SF6 gas, the amount of its inner SF6 gas is very little, repeatedly after sampling, also needs tonifying Qi.Both expend manpower, also expended financial resources.And operating SF6 gas also exists certain toxicity, once reveal in sampling process, people is known from experience and damaged.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide one to save in sampling process, to connect multiple joint, be convenient to SF6 gas sample, and the gas of getting strictly according to the facts gas truth in reflection equipment, can also in sampling, vacuumize with tonifying Qi operation, can improve sampling qualification rate and guarantee the device that carries out gas sample test to filling the power equipment of SF6 gas of personal security in sampling process.
The purpose of this utility model is achieved through the following technical solutions.
Multi-functional SF6 gas sampling device, this device includes the vacuum pump being installed in cover body, the coiled snubber assembly being connected with vacuum pump outlet by pipeline, on the other end pipeline of snubber assembly, be connected with four-way, on the first pipeline connecting at four-way, pressure detection device is installed, on the second pipeline that four-way connects, be provided with No. 1 air valve and No. 2 air valves, on the 3rd pipeline that four-way connects, be provided with No. 3 air valves and No. 4 air valves, on the pipeline of snubber assembly connection four-way, be provided with air valve No. 5; In described coiled snubber assembly adopts, polishing pipeline dish system forms, and the first pipeline, the second pipeline and the 3rd pipeline that four-way connects all adopt interior polishing pipeline.
The second pipeline of the present utility model and the 3rd pipeline be arranged in parallel.On cover body, be provided with door-plate and view window.
It is not to be adsorbed when making SF6 gas flow by the road that coiled snubber assembly of the present utility model and the pipeline that is connected on four-way adopt polishing pipeline, truly to reflect the gas situation in power equipment.On two pipelines, set up four air valves separately, can control gas flow, be convenient to vacuumize, any demand of sampling, tonifying Qi.Set pressure detection device can detect by the pressure to package unit in sampling process, Real Time Observation sampling degree.
Adopt the utility model scheme, can conveniently utilize on two pipelines, arrange any two air valve interfaces once connected conventional sample steel cylinder vacuumize, sample operation, need not repeatedly connect, both handled easily had also guaranteed the impermeability of whole sampling link.And in sampling process, can, by the gaseous tension in pressure detection device real-time monitored equipment, the in the situation that of insufficient pressure, can in sampling, utilize two air valve interfaces of residue to carry out instant tonifying Qi.Utilizing after two interfaces sample, directly utilize remaining two interfaces repeatedly to sample.Or can connect three sample steel cylinders, vacuumize operation simultaneously.
