The utility model discloses PE flange protective layer's protectiveness is strong, convenient to use.
Description
Technical Field
The utility model relates to a pipe connection spare technical field especially relates to a PE flange protective layer.
Background
The chemical industry is very common in the production industry, and in the chemical industry, a large number of storage tanks and pipelines are connected, flanges are parts for connecting the pipelines and the storage tanks, and adjacent flanges are fixed by bolts. Because a lot of raw materials have corrosivity in the chemical production, consequently can select steel lining PE storage tank and PE flange to improve the security of production, this kind of storage tank passes through the flange joint back with the pipeline, and the junction has partial PE material to expose in the air, receives the wind-blown sun and rain to drench, and difficult the avoiding can be ageing, corrodes, and then leads to the material to leak, causes the threat to production staff's safety.
Patent CN201721805638 discloses a stainless steel flange protective sleeve, which includes a left sleeve body and a right sleeve body, a sleeve opening and closing opening capable of being closed or opened is formed between the left sleeve body and the right sleeve body, the left sleeve body and the right sleeve body form a cylindrical flange sleeve body after being closed, a shaft opening with a tightening assembly is arranged at the upper end and the lower end of the flange sleeve body, and the flange protective sleeve can be used on different flanges to protect the flanges from corrosion; above-mentioned protective sheath has certain guard action to the flange, but can't protect the PE flange and receive other influences such as high temperature, and this protective sheath installation is loaded down with trivial details, can't agree with the flange of special position, prevents that the leakage effect is relatively poor, is unfavorable for routine maintenance simultaneously.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a PE flange protective layer to solve the problem that above-mentioned prior art exists, improve the protectiveness to the flange.
In order to achieve the above object, the utility model provides a following scheme:
the utility model provides a PE flange protective layer, including lower protective layer and last protective layer, the lower protective layer with it all is used for the parcel on the pipe connection pipe of flange to go up the protective layer, the lower protective layer is located the pipe connection pipe with go up between the protective layer, the lower protective layer with it passes through the elasticity firmware connection to go up the protective layer.
Preferably, the elastic fastener is a buckle.
Preferably, the lower protective layer is a PE winding film, and the upper protective layer is aluminum foil paper.
Preferably, the outer diameter of the pipeline connecting pipe is D, the length of the lower protection layer is 0.8 pi D, and the length of the upper protection layer is 1.1 pi D.
Preferably, the lower protective layer is in close contact with the pipe connection pipe, and the upper protective layer is in close contact with the lower protective layer.
The utility model discloses for prior art gain following technological effect:

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The utility model aims at providing a PE flange protective layer to solve the problem that above-mentioned prior art exists, improve the protectiveness to the flange.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1 to 3: the embodiment provides a PE flange protective layer, including lower protective layer 2 and upper protective layer 3, lower protective layer 2 and upper protective layer 3 all are used for the parcel on the pipe connection pipe of flange, and lower protective layer 2 is located between pipe connection pipe and the upper protective layer 3, and lower protective layer 2 and upper protective layer 3 are connected through elasticity firmware 4. The lower protective layer 2 is in close contact with the pipe connecting pipe, and the upper protective layer 3 is in close contact with the lower protective layer 2.
In this embodiment, the elastic fastener 4 is a buckle, the lower protective layer 2 is a PE wrap, and the upper protective layer 3 is an aluminum foil. The outer diameter of the pipeline connecting pipe is set to be D, the length of the lower protection layer 2 is set to be 0.8 pi D, and the length of the upper protection layer 3 is set to be 1.1 pi D.
The PE flange protective layer of the embodiment is used as follows:
because the length of lower protective layer 2 is less than the girth of the cross section excircle of pipeline connecting pipe, so at first need stretch lower protective layer 2 and parcel on the outer wall of the pipeline connecting pipe of PE flange 1 to make the both ends of lower protective layer 2 link firmly through elasticity firmware 4, with this fixed of realization lower protective layer 2. Then wrap up upper protective layer 3 in the outside of lower protective layer 2 closely to make the both ends of upper protective layer 3 link firmly through elasticity firmware 4, and also link firmly through the elasticity between upper protective layer 3 and the lower protective layer 2 and be connected, so just realized the application of this embodiment PE flange protective layer.
The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope. In summary, the content of the present specification should not be construed as a limitation of the present invention.
