Description
Technical field
A kind of measurable gas storage device is the utility model is related to, belongs to gas detection equipment technical field.
Background technology
The fields such as industry, scientific research, teaching, health are in the work such as gas analysis detection and the relevant physico-chemical property research of gas
In often need to carry out the collection of gas, mixture, storage etc..It need to particularly carry out generating gas on-line checking under certain scene in real time
When, gas storage device can realize that gas collection and metering will have sufficient practicality at the same time.
In the prior art, common gas storage device or be rigid container, or be flexible collection airbag etc., these devices lead to
The metering of stored gas cannot be often directly realized by, or can only realize the definite without energy continuous metering of total amount.And test
Frequently with modes such as draining water gathering of gas law in room, then the collection storage that ammonia, carbon dioxide etc. are dissolved in the gas of water cannot be carried out.
It can use the shifting sample instrument that syringe etc. can be quantitative roughly, or quantifying on time, but this are carried out using the pump housing of stability of flow
A little modes need to rely on other utensils, and usage scenario is limited, and complicated.
Patent CN201310365440.2 discloses a kind of " gasometry mixture and rate controlling based on water-gas replacement technique
Carrying method and device ", the device include a rigid water container and the flexible containers set in it, by water,
Gas displacement principle, control water container discharge water or water filling control flexible containers air inlet or gas transmission, keep air pressure balance and
The accurate formulation of mixed gas is realized under conditions of temperature stabilization and is stablized and is conveyed.Although the technical solution can be by water
The metering to gas in container is realized in metering, but need to be equipped with control and the metering device of a set of water, complicated, troublesome in poeration,
And gas uniformly mixes difficulty.
In view of foregoing existing technical problem, should develop a kind of gas storage device with more excellent function of measuring, with convenient
The work such as the collection of gas, mixture, detection.
The content of the invention
The purpose of this utility model is to provide a kind of two-stage metered shot device of achievable degree of precision.
Used technical solution is：
A kind of measurable gas storage device, including air reservoir body, the air reservoir body are bellows closed at both ends
The flexible cylinder of shape；The flexible cylinder is equipped with gas inlet and outlet；The length of the flexible cylinder corresponds to the storage of gas storage device
Tolerance.
Further, the flexible cylinder suspension is set, and is made freely to stretch in the vertical and is contacted sides from other
Frictional influence；And the active force that the weight of its own keeps down, avoids being similar to when keeping flat due to caused by flexible hysteresis
Error.
Further, base and the stand being arranged on the base are further included；The stand includes column, and is arranged on
The crossbeam of the column upper end；The flexible cylinder is hung on the crossbeam, thus can freely be exchanged for, easy to use.
Further, column of the side of the flexible cylinder close to the stand；The column is equipped with scale, with degree
Measure the length of the flexible cylinder.
Further, the scale on the column is labeled as the air storage amount of gas storage device.
Further, the gas inlet and outlet is separately positioned on the both ends of the flexible cylinder.
Further, the gas inlet and outlet of the lower end of the flexible cylinder is picked out using flexible hose, avoids pipeline band
Askew flexible cylinder, causes error in reading.
Further, the lower end of the flexible cylinder is equipped with clump weight, suitably increases weight, strengthens downward active force,
Make holding vertical, facilitate reading；And error caused by flexible hysteresis when avoiding injecting, releasing gas.
In conclusion the measurable gas storage device the utility model discloses a set of achievable degree of precision.During gas collection, gas
Sample enters from one end of gas inlet and outlet, and as needed, the other end connection of gas inlet and outlet needs gas port or closure.With entrance
The tolerance increase of flexible cylinder, flexible cylinder constantly extend；Discharged with the gas sample of flexible cylinder, tolerance is constantly reduced, retracting cylinder
Body 4 constantly shortens；Air storage amount can be directly read according to scale.It can be marked by injecting the gas of multiple known quantities on column
Scale, realize using the device carry out gas collection when accurate measurement.
The measurable gas storage device of the utility model is particularly suitable for generating the online collection of gas in real time reaction scene
And detection, compared with prior art, the measurable gas storage device of the utility model realizes gas collection and metering at the same time, convenient and practical,
It is simple in structure, it is of low cost.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of measurable gas storage device in the utility model.
Embodiment
For the technological means of the utility model and beneficial effect is expanded on further, below in conjunction with attached drawing and preferred embodiment,
A kind of measurable gas storage device of the utility model is described in detail：
As shown in Figure 1, measurable gas storage device includes the flexible cylinder 4 of corrugated tube shape closed at both ends as air storage appearance
Device body；And base 6 and the stand that is arranged on base 6；Stand includes column 2 and the crossbeam 1 for being arranged on 2 upper end of column；
Flexible cylinder 4 is hung on crossbeam 1；Column 2 of the side of flexible cylinder 4 close to stand；Flexible 4 length of cylinder has corresponded to air storage
The air storage amount of device；Column 2 is equipped with scale.Using the flexible cylinder 4 of gas injection of known quantity, corresponding scale is labeled as air storage
The air storage amount of device.
The both ends of flexible cylinder 4 are respectively equipped with gas inlet and outlet and pick out pipeline 3 respectively, and inlet and outlet can make no distinction of rank；
Or mixed gas, the setting for the air inlet order that can be carried out according to needed for the density of prepackage gas sample judges uniformly mixing.Retracting cylinder
The gas inlet and outlet of the lower end of body 4 is picked out using flexible hose；The lower end of flexible cylinder 4 is equipped with clump weight 5, makes flexible cylinder
4 keep vertical.
During gas collection, gas sample enters from one end of pipeline 3, and as needed, the other end connection of pipeline 3 needs gas port or closes
Close.With the tolerance increase for entering flexible cylinder 4, flexible cylinder 4 constantly extends；Discharged with the gas sample of flexible cylinder 4, tolerance is continuous
Reduce, flexible cylinder 4 constantly shortens；Air storage amount can be directly read according to scale.
Above description is specific embodiment of the present utility model, is respectively illustrated not in the essence of the utility model
Appearance is construed as limiting, and person of ordinary skill in the field makes an amendment or deforms to foregoing embodiment, without departing substantially from this reality
With new essence.
