Description
【Technical field】
The utility model is related to wellbore apparatus, and in particular to a kind of pit shaft with insect prevention corrosion.
【Background technology】
The multifarious type of various pit gears is various in the market, and it is anti-that what either what material made is unable to anti-corrosion
Worm is unable to autoprotection oneself, leads to these pit shaft reduced service life, increases the cost of facility itself.
Therefore a kind of pit shaft with insect prevention corrosion is needed, household demand can not only be met, while municipal need can also be met
It asks, this pit shaft with insect prevention corrosion of my invention, simple in structure thus, easy to process, not only meets household demand,
Also it can meet municipal demand.
【Utility model content】
The technical problem to be solved by the present invention is to the multifarious type of various pit gears is various in the market, nothing
By be what material make be unable to antiseptic insect-repelling, be unable to autoprotection oneself, lead to these pit shaft reduced service life, increase
It adds and applies the cost of itself, in view of the above problems, proposing a kind of pit shaft with insect prevention corrosion, simple in structure, processing side
Just, not only meet household demand, can also meet municipal demand.
Technical solution is as follows used by the utility model solves above-mentioned technical problem：
A kind of pit shaft with insect prevention corrosion, which is characterized in that including matrix (1), outer layer of polyethene (2), spy
Fluorine dragon internal layer (3), Teflon upper layer (4), polyethylene bottom (5) are constituted, the outer layer of polyethene (2) and polyethylene bottom
(5) integral, described ethylene outer layer (2) inner headed face is made with matrix (1) periphery to match.
A kind of pit shaft with insect prevention corrosion, which is characterized in that the Teflon internal layer (3) and Teflon
Upper layer (4) makes integral, described Teflon internal layer (3) periphery matrix (1) inner headed face and matches.
A kind of described pit shaft with insect prevention corrosion, which is characterized in that the matrix (1) by outer layer of polyethene (2),
The chamber that is fully sealed that Teflon internal layer (3), Teflon upper layer (4) and polyethylene bottom (5) four are formed is surrounded, to reach
Protect the purpose of family matrix (1).
A kind of pit shaft with insect prevention corrosion, which is characterized in that the Teflon upper layer (4) and polyethylene
Outer layer (2) interface corrodes strength gluing knot using insect prevention, completes sealing state, the Teflon internal layer (3) and polyethylene
Bottom (5) interface uses anti-corrosion strength gluing knot, equally reaches fully sealed position.

【Specific implementation mode】
1, Fig. 2, Fig. 3 below in conjunction with the accompanying drawings, Fig. 4 pit shaft with insect prevention corrosion a kind of to the utility model are done further in detail
It describes in detail bright.
It is described in the utility model it is a kind of with insect prevention corrosion pit shaft preferred embodiment in, the outer layer of polyethene
(2) it makes integral, described ethylene outer layer (2) inner headed face with polyethylene bottom (5) and matches with matrix (1) periphery.
It is described in the utility model it is a kind of with insect prevention corrosion pit shaft preferred embodiment in, the matrix (1) is gathered
What ethylene outer layer (2), Teflon internal layer (3), Teflon upper layer (4) and polyethylene bottom (5) four were formed is fully sealed chamber institute
It surrounds, to achieve the purpose that protect family matrix (1).
It is described in the utility model it is a kind of with insect prevention corrosion pit shaft preferred embodiment in, the Teflon upper layer
(4) strength gluing knot is corroded using insect prevention with outer layer of polyethene (2) interface, completes sealing state, the Teflon internal layer
(3) anti-corrosion strength gluing knot is used with polyethylene bottom (5) interface, equally reaches fully sealed position.
The technical problem to be solved by the present invention is to the multifarious type of various pit gears is various in the market, nothing
By being that the insect prevention that is unable to what material makes is corroded, it is unable to autoprotection oneself, leads to these pit shaft reduced service life, is increased
It adds and applies the cost of itself, in view of the above problems, proposing a kind of pit shaft with insect prevention corrosion, simple in structure, processing side
Just, not only meet household demand, can also meet municipal demand.
As described above, the only preferred embodiment of the utility model, when cannot be limited with this utility model implementation range,
All still belong to the utility model according to simple equivalent changes and modifications made by the utility model claim and novel description generally
In the range of patent covers.
