Description
Technical field
The utility model is related to gas sampling assembly, more particularly to a kind of gas sampling bag.
Background technology
Gas sampling bag, also known as air sampling bag, or Tedlar（Tedlar）Bag is a kind of for gathering and storing gas
The container of sample.Sampler bag is usually rectangle or square, and volume is raised to 50 liters from 0.2, and common is 1 liter and 5 liters.Remove
Outside bag, sampler bag is commonly provided with the parts such as valve and hanging hole（Fig. 1）.Bag material according to the gas adopted requirement
Difference, common are polyvinyl fluoride（Tedlar）Film, polyfluorinated ethylene（Teflon）Film, polyvinylidene fluoride film（PVDF）, gather complete
Fluoro ethyl propene film（FEP）, polyethylene film（PE）, and aluminium foil etc..Gas sampling bag is mainly used in environment monitoring or chemical industry was manufactured
Gaseous sample collection in journey, the storage and dilution of the gas standard specimen being also used in analytical methods.
Collection of the sampler bag to gaseous sample, generally there is two methods, i.e. pressure-injected and vacuum inhalation.Pressure is noted
Entering method will be pressed into sampler bag by gas production body with pump or syringe.This method has two shortcomings, and one must make when being sampling
With pump, syringe or other intensifiers, two is easily by cross pollution, or quilt when institute's gas production body is shifted by pump or syringe
Absorption, particularly influences larger when the analyte, such as volatile organic matter (VOCs) of low concentration is gathered.Therefore, actual work
It is more using second acquisition method-vacuum inhalation in work.The method is worked as using the general principle of physics
Gas pressure in sampling container less than by gas production body pressure when, known from experience by gas production in automatically flowing into sampling container.Tool rigidity
The sampling container on surface, such as stainless steel gas sampling tank（Soviet Union's code tank）, can vacuumize in advance before sampling, opened until sampling
Valve is that will be sucked by gas production body using vacuum in tank.However, the bag film of sampler bag is very thin, without rigidity, it is impossible to use
The mode of sample can is sampled, but must be by means of sampling box（Duricrust box, there is provided vacuum environment）And vavuum pump（Vacuum is provided
Source）.Sampling preparatory stage, sampler bag is placed in sampling box, and a sampling pipe is connected at its valve, penetrates sampling tank wall to sample
At collection（Fig. 2）.When sampling starts, start the air that vavuum pump is drawn in sampling box, in sampling box（Outside sampler bag）Shape
Into negative pressure, the sampled pipe of gaseous sample flows into sampler bag and is collected.This is current spot sampling（Such as gather various pollution sources
Gas sample）In the most commonly used airbag sample mode.Obviously, this sampling box adds the sample mode of vavuum pump, sample collector
Except sampling box and vavuum pump need to be carried with（Or other supercharging equipments）, in addition it is also necessary to connect sampling conduit and vacuum pipe, leakage detection
Etc. step, sampling process is relatively complicated.
Utility model content

There is the handle being rotatably connected with it.
The handle is arranged in pairs, and can be rotated to the direction away from sampler bag body, or is got up by folding, when described
When handle is got up by folding, it is in same plane with the handle body.
On the handle or handle body is referring to hole near the arc that is respectively provided on two sides with of handle.
The handle body is provided with air nozzle hole.
The valve is located at the middle part of the sampler bag body, and the escaping pipe of the valve end is perpendicular to the sampler bag
The outer surface of body.
The handle body is provided with air nozzle hole, and the air nozzle hole is located at the middle part of the handle body.
The sampler bag body includes Primary layer and coating layer, and the Primary layer forms the matrix of the sampler bag body,
The coating layer is the enhancement layer being compounded in outside the Primary layer.
The Primary layer is polyvinyl fluoride Tedlar film layers, polyfluorinated ethylene Teflon film layer, polyvinylidene fluoride film PVDF
One kind in film layer, perfluoroethylene-propylene fep film layer.
The coating layer is at least two-layer, and the coating layer is polyethylene film layer or aluminium foil layer.
The beneficial effects of the utility model：The utility model devises handle apparatus on sampler bag, and handle apparatus are not beaten
Into a rectangle for plane when opening, the upper and lower surface of sampler bag is respectively attached to, a portion of handle apparatus is connected in adopts
On sample bag, there is the handle that can be dug upwards in outside, the sampler bag for having handle apparatus, very easy to use, during sampling, valve
Alignment needs the place of sampling, is turned on handle, and both hands are stretched out, you can by gaseous sample suction sampler bag.Also, this reality
Bag is improved by the way of multilayer coating film with new sampler bag body, strengthens the lucifuge performance of bag, improve it
Mechanical strength, is conducive to protecting the stability of wherein sample gas.
Compared with the existing sampler bag of in the market, the sampler bag disclosed in the utility model carries hand pulling type sampling apparatus,
Extra sampling apparatus need not be relied on when using（Sampling pump, syringe, sampling box and vavuum pump etc.）, greatly facilitate field condition
Sampling.In addition, the sampler bag in the utility model has lucifuge performance, light is prevented to enter and improve active gases in bag
Stability.Also, the stretch-proof that greatly strengthen and the mechanical performance of resistant to collapsing of the sampler bag in the utility model, substantially
Avoid because sampler bag rupture and caused by sample loss, improve sample storage and transportation in security.
