Abstract
The utility model discloses constant pressure water sample bottle, including bottle and bottle cap, bottle includes body and bottleneck, and bottleneck lower end is provided with external screw thread, and bottleneck upper end is provided with exhaust passage；The upper end of closure inside is provided with leak-proof gasket, and the lower end of closure inside is provided with the internal thread coordinated with external screw thread；Bottleneck is uniformly distributed multiple exhaust passages, make the air communication outside air and bottle in bottle, when filter paper folding funnel is directly carried out into water sample filtering, make bottle external and internal pressure moment identical, water sample can in the presence of pressure itself rapid filtration, no longer there is the situation that the excessive water sample rate of filtration of air pressure in bottle is slow or can not filter.
Description
Technical field
Sampler field is the utility model is related to, specially a kind of constant pressure water sample bottle.
Background technology
Before water sample chemical examination, the water sample of collection need to be filtered, it is main to remove wherein impurity, 100ml polyethylene bottles
One of water sample storage articles for use.The filter paper that water sample filtering is typically folded using being put on glass filtration funnel is carried out；According to reality
Code and requirement are tested, there cannot be contact to mix between the water sample of chemical examination, and a part can be remained on used glass funnel wall
Water sample is filtered, therefore can not be repeated.The cleaning of glass filtration funnel is 1:Soaked more than 24 hours in 4 salpeter solution,
Then use distilled water flushing 3 times, then use deionized water rinsing；When water sample is more, it is necessary to substantial amounts of glass filtration funnel, glass
The cleaning task of funnel is very arduous.
To avoid cumbersome glass funnel cleaning, filter paper directly can be folded into funnel and carry out water sample mistake
Filter.But the bottleneck of polyethylene is rounder and more smooth, when water sample filters, the filter paper of moistening is close to bottle mouth position, additional water sample isolation
Gas inside and outside bottle, gas volume is gradually reduced in bottle when water in bottle sample gradually increases, and air pressure increases, the water sample rate of filtration by
Gradual change is slow；When air pressure reaches outside bottle in the case of air pressure and water sample hydraulic pressure sum in bottle, water sample can not be flowed into bottle, and filtering stops
Only filtered again, it is necessary to change filter paper, cumbersome and efficiency is low.
Utility model content
The utility model aims to overcome that the deficiency of the above, there is provided a kind of constant pressure water sample that can discharge gas in bottle
Bottle, it is very easy to use.
The utility model purpose is achieved through the following technical solutions such a constant pressure water sample bottle, including bottle and bottle cap, described
Bottle includes body and bottleneck, and the bottleneck lower end is provided with external screw thread, and bottleneck upper end is provided with exhaust passage；
The upper end of the closure inside is provided with leak-proof gasket, the lower end of the closure inside is provided with coordinate with external screw thread in
Screw thread.
As preferred：The exhaust passage is steam vent or air discharge duct, exhaust passage through connection bottleneck inside and outside wall.
As preferred：The leak-proof gasket is in π type shapes, and leak-proof gasket is made up of elastomeric material, and leak-proof gasket lower end is straight
Footpath is more than upper end diameter.
As preferred：The body is marked with volume markings.
As preferred：The lower end of the bottle cap wall is provided with vent.
As preferred：The constant pressure water sample bottle is made up of polythene material.
The utility model has advantages below：The utility model is uniformly distributed multiple exhaust passages in the bottleneck of polyethylene,
Make the air communication outside air and bottle in bottle, when filter paper folding funnel is directly carried out into water sample filtering, make in bottle
The external pressure moment is identical, water sample can in the presence of pressure itself rapid filtration, no longer there is the excessive water sample mistake of air pressure in bottle
Filtering velocity degree is slow or situation about can not filter.And equally distributed multiple exhaust passage designs are set above screw thread in bottle cap
Having prevents the leak-proof gasket of exhaust passage and bottleneck leak, keeps water-tight in the state of bottle cap screwing, does not influence polyethylene
Other purposes of water sample bottle.
Prior art is if it is desired to preventing that the excessive water sample rate of filtration of air pressure in polyethylene water sample bottle is slow or can not filter
Situation, glass funnel typically is placed on polyethylene water sample bottle, the filter paper folded is put into glass funnel, such filter paper
It is not directly contacted with polyethylene water sample bottle；But according to Experimental Procedures, mixing, each water sample filtering can not be contacted between each water sample
When will use the funnel that cleans up, in the case where sample is more, the method is very inconvenient；Use this polyethylene constant pressure
Water sample bottle, it is only necessary to filter paper is rolled well, bottleneck is positioned over and directly filters, water sample just can be in rapid filtration under pressure itself, greatly
The big efficiency for improving experiment.

Embodiment：
In order to deepen to understanding of the present utility model, below in conjunction with example and accompanying drawing to the utility model constant pressure water sample bottle
It is described in further detail, the example is only used for explaining the utility model, does not form the restriction to scope of protection of the utility model.
The embodiment of this constant pressure water sample bottle is shown as shown in Figure 1, Figure 2, constant pressure water sample bottle is made up of polythene material, including
Bottle and bottle cap, bottle include body 1 and bottleneck 2, and the lower end of bottleneck 2 is provided with external screw thread 3, and the upper end of bottleneck 2 is provided with steam vent
4-1 or air discharge duct 4-2；
Fig. 3 is the Bottle cap structure schematic diagram of constant pressure water sample bottle, and Fig. 4 is the bottle cap top view of constant pressure water sample bottle, closure inside
Upper end be provided with leak-proof gasket 5 in π type shapes, leak-proof gasket 5 is made up of elastomeric material, and the lower end diameter of leak-proof gasket 5 is more than
Upper end diameter, leak-proof gasket 5 are used to prevent liquid from spilling by steam vent 4-1, air discharge duct 4-2 and bottleneck；Under closure inside
End is provided with the internal thread 6 coordinated with external screw thread 3;Body 1 is marked with volume markings；The lower end of bottle cap wall is provided with vent 7.
In summary, novel constant-pressure water sample bottle solves the problems, such as that air pressure is excessive in bottle in water sample filter process, accelerates water
The speed of spline filter, reduce the waste of experimental article and the consumption of manpower.
It is to be also not limited to the example above, this skill to limitation of the present utility model, the utility model that described above, which is not,
The variations, modifications, additions or substitutions that the those of ordinary skill in art field is made in essential scope of the present utility model, also should
Belong to the scope of protection of the utility model.
