Abstract
A kind of device adopting direct drainage measurement gas volume, it comprises cylindrical shell, the stack shell of cylindrical shell is provided with volume markings, cylindrical shell top and bottom are respectively equipped with top cover and bottom, top cover is provided with draft tube and valve, the lower end of the upper end of top cover and cylindrical shell, bottom and cylindrical shell is threaded connection, all detachably.Compared to the direct drainage utilizing graduated cylinder, the utility model can improve measurement efficiency and the measurement accuracy of direct drainage.
Description
Technical field
The utility model relates to field of experiment equipment, is specifically related to a kind of device adopting drainage measurement gas volume.
Background technology
In production and scientific research activity, often can run into and need gas-monitoring volume.At present, the technical scheme of measurement gas volume mainly contains: gas meter method and drainage.For gas meter method, gas market for different physicochemical property there is the gas meter of extensive stock can select for user, the gas meter wherein had can only gas-monitoring flow (as glass rotameter), what have then can record the gas volume (wet test meter as tape counter) passed through in certain hour indirectly, its advantage be measure accurately, conveniently save trouble, be applicable to large discharge gas volume monitoring, its shortcoming be cost of equipment higher, be not too applicable to low discharge or discontinuous air-flow gas-monitoring; For drainage, in practical application, indirect method and indirect method can be divided into again.Direct method normally first adopts gas collection bag to collect gas, then records gas volume by wide range graduated cylinder by drainage; Indirect rule is that the volume by measuring draining obtains gas volume data indirectly.The advantage of drainage is that measurement cost is low, the gas volume be applicable in scientific research activity is measured.Relative to gas meter method, the shortcoming of conventional discharge method is easily because manual operation causes measured deviation, affects data accuracy, but also more bothersome.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of device adopting direct drainage measurement gas volume provided.Compared to the direct drainage utilizing graduated cylinder, the utility model can improve measurement efficiency and the measurement accuracy of the method.
The object of utility model is achieved in that
A kind of device adopting direct drainage measurement gas volume, it comprises cylindrical shell, and the stack shell of cylindrical shell is provided with volume markings, and cylindrical shell top and bottom are respectively equipped with top cover and bottom, top cover is provided with draft tube and valve, and the lower end of the upper end of top cover and cylindrical shell, bottom and cylindrical shell is threaded connection.
Described cylindrical shell top is divided into tubular, bottom is divided into inverted cone-shaped structure.
The lower part of described cylindrical shell is provided with stopping water level line.
Described top cover and open top, bottom are with bottom opening and are threaded.
Described cylinder body bottom is provided with support.
Described support is A-frame.
Described valve is ball valve.
Adopt said structure, during use, first device entirety is put into the container filling certain water, and make device bottom cover member immerse below the water surface; Open top cover of cylinder body, tighten the bottom of bottom, add water in device; Tighten top cover of cylinder body, the conduit connecting gas collection bag is received draft tube; Ball valve is threaded to opening, twists off bottom blind nut; Artificially apply pressure to gas collection bag, by gas press-in device, the water in this timer is discharged from bottom, and water level inside declines.After gas drains in gas collection bag, directly can read gas volume data from the volume markings apparatus main body; If gas does not also drain in gas collection bag, the water level in apparatus main body has just been down to stopping water level, then should close ball valve, turn on top cover, again add water, then repeat above-mentioned steps, until gas drains in bag, cumulative the data obtained the final volume of gas to be measured.
Compared to the direct drainage utilizing graduated cylinder, this device can reduce the repetitive operation number of times in isodose gas volume measuring process, improves and measures efficiency and data accuracy.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
Adopt the device of direct drainage measurement gas volume as shown in Figure 1, it comprises cylindrical shell 1, the stack shell of cylindrical shell 1 is provided with volume markings, cylindrical shell 1 top and bottom are respectively equipped with top cover 2 and bottom 6, top cover 2 is provided with draft tube 4 and valve 5, and upper end, the bottom 6 of top cover 2 and cylindrical shell 1 are threaded connection with the lower end of cylindrical shell 1.
Described cylindrical shell 1 top is divided into tubular, bottom is divided into inverted cone-shaped structure.
The lower part of described cylindrical shell 1 is provided with stopping water level line 7.
Described top cover 2 and open top 9, bottom 6 are with bottom opening 3 and are threaded.
Be provided with support 8 bottom described cylindrical shell 1, support 8 is A-frame.
Preferably, valve 5 is ball valve.
Adopt said structure, during use, first device entirety is put into the container filling certain water, and make device bottom cover member immerse below the water surface; Open top cover of cylinder body, tighten the bottom of bottom, add water in device; Tighten top cover of cylinder body, the conduit connecting gas collection bag is received draft tube; Ball valve is threaded to opening, twists off bottom blind nut; Artificially apply pressure to gas collection bag, by gas press-in device, the water in this timer is discharged from bottom, interior water level decreasing.After gas drains in gas collection bag, directly can read gas volume data from the volume markings apparatus main body; If gas does not also drain in gas collection bag, the water level in apparatus main body has just been down to stopping water level, then should close ball valve, turn on top cover, again add water, then repeat above-mentioned steps, until gas drains in bag, cumulative the data obtained the final volume of gas to be measured.
