Abstract
The utility model relates to a volume box used for detecting expansion times of a gas extraction hole drilling and sealing material. The volume box comprises a volume box main body and is characterized in that the volume box main body is a cube with an open upper end, a transparent window is arranged on one side of the volume box main body, and scale identifiers are arranged at one side of the transparent window. The volume box used for detecting expansion times of the gas extraction hole drilling and sealing material has the advantages that structure is simple, the expansion times of the gas extraction hole drilling and sealing material can be detected by virtue of simple operation and calculation, and great convenience can be provided for a user.
Description
Technical field
The utility model relates to a kind of colliery control gas articles for use, a kind of volume case of checking mash gas pumping drilling sealing material expansion multiple of more specifically saying so.
Background technology
Coal mine gas extraction borehole sealing material generally uses macromolecule expanding materials such as polyurethane at present, and does not generally have the Production Check Equipment of specialty that the expansion multiple of sealing material is tested as the mine of applying unit.
Summary of the invention
The purpose of this utility model is in order to remedy the deficiencies in the prior art, to provide a kind of and can and calculate the volume case of checking mash gas pumping drilling sealing material expansion multiple by shirtsleeve operation.
The purpose of this utility model can realize in the following manner: a kind of volume case of checking mash gas pumping drilling sealing material expansion multiple, include the volume box main body, be characterized in that described volume box main body is the cube shaped of upper end open, a side of volume box main body is provided with transparent window, and a side of transparent window is provided with scale marker.
The utility model compared with prior art has following advantage: simple in structure, and can and calculate and just can check out mash gas pumping drilling sealing material expansion multiple through shirtsleeve operation, bring a lot of facilities to the user.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Embodiment
As follows with reference to accompanying drawing: a kind of volume case of checking mash gas pumping drilling sealing material expansion multiple, include volume box main body 1, be characterized in that described volume box main body 1 is the cube shaped of upper end open, a side of volume box main body 1 is provided with transparent window 2, and a side of transparent window 2 is provided with scale marker 3.
In volume box main body 1, add some water during use earlier, observe height of water level by transparent window 2, write down height of water level, do not have sealing material in the entry fully, observe height of water level by transparent window 2, write down height of water level again, twice height of water level difference is exactly the volume before the sealing material expansion; Allow after the sealing material reaction, the operating process of measuring the reacted volume of sealing material is similar.Can calculate the volume ratio of sealing material expansion front and back thus, whether the check product is qualified, and the utility model is simple in structure, with low cost, is easy to make.
