Abstract
The utility model relates to a polyethylene tube material for a coal mine, comprising a polyethylene tube body, wherein a ring of metal wire mesh layer is arranged at the middle of the polyethylene tube body. According to the polyethylene tube material for a coal mine disclosed by the utility model, a ring of metal wire mesh layer is arranged at the middle of the polyethylene tube body, so that the overall structural strength of the tube material is enhanced and meets the safety requirements of the coal mine; and moreover, the polyethylene tube material is easier to pave than a metal tube material.
Description
Technical field
The utility model relates to a kind of tubing, is specifically related to a kind of coal mine and uses polyvinyl piping materials, and it can be applicable to the pipe network systems such as water supply, draining, pressure wind, whitewashing and extraction watt silk under the coal mine.
Background technique
For guaranteeing the production safety under the coal mine, when coal excavates, must guarantee the ventilation of down-hole, assemble to avoid gas, coal dust.
The coal mine method of ventilation of existing technology mainly is that tubing is fed the down-hole, thereby realizes ventilating and firedamp drainage.And the tubing that adopts is essentially metal tube, and the user cost of metal tube is higher, and the laying difficulty is also bigger.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of and have structure improved coal mine and use polyvinyl piping materials, to overcome said defective of the prior art.
The model utility content
For addressing the above problem, the purpose of the utility model is to provide a kind of structural strength high, and lays easy coal mine and use polyvinyl piping materials.
For realizing above-mentioned purpose; The technological scheme that the utility model is taked is: a kind of coal mine is used polyvinyl piping materials; It comprises a polyethylene body; In the middle of said polyethylene body, be provided with a circle oven wire mesh blanket, the thickness of said oven wire mesh blanket is 0.2mm, and the cross section of said polyethylene body is rounded.
Compared with prior art; The utlity model has following beneficial effect: the coal mine of the utility model is enclosed oven wire mesh blanket with polyvinyl piping materials through in the middle of the polyethylene body, being provided with one; Thereby strengthened the overall construction intensity of this tubing, made it meet the safety requirement of coal mine; And this polyvinyl piping materials is easy to lay than metal pipe.
Description of drawings
Fig. 1 is the sectional view of the coal mine of the utility model with polyvinyl piping materials.
Embodiment
See also shown in the Figure of description 1, the utility model is that a kind of coal mine is used polyvinyl piping materials, and it comprises a polyethylene body 1, the rounded structure of the cross section of this polyethylene body.
The coal mine of the utility model is with polyvinyl piping materials greatest improvement part: in the middle of said polyethylene body 1, be provided with a circle oven wire mesh blanket 2, the thickness of this oven wire mesh blanket 2 is 0.2mm.
The coal mine of the utility model is enclosed oven wire mesh blanket 2 with polyvinyl piping materials through in the middle of polyethylene body 1, being provided with one, thereby has strengthened the overall construction intensity of this tubing greatly, makes it meet the safety requirement of coal mine; And this polyvinyl piping materials is easy to lay than metal pipe.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
