Abstract
The utility model discloses a poly ethylene (PE) pipe counter flange. The PE pipe counter flange comprises a flange body. A trapezoidal concave ring groove is arranged in the counter surface of the flange body, the bottom width of the concave ring groove is larger than that of the opening portion, and a sealing gasket with a corresponding size is arranged on the counter surface. A position of the sealing gasket, corresponding to the concave ring groove, is provided with a trapezoidal convex ring groove, and the convex ring groove is embedded into the concave ring groove. Due to the fact that the sealing gasket matching tightly is arranged on the counter surface of the PE pipe counter flange, the PE pipe counter flange enables the sealing gasket to be positioned accurately, not to slip easily, and to be safe and reliable, and meanwhile, the PE pipe counter flange brings convenience to installation on construction sites.
Description
Technical field
The utility model relates to a kind of PE pipe abutted flange, particularly a kind of PE pipe abutted flange of being convenient to install.
Background technique
Generally all need when existing pipe first-aid or pipeline joint flange is docked, the general interface of flange in the market is provided with simple annular recess, during docking gasket seal is filled between two relative flanges, bulge loop groove and the annular recess on the flange on the gasket seal are compressed.At the scene in construction or the repairing process; owing to the reason such as the space of the restriction in place, acting flange is little; gasket seal often can occur and vertically fill in difficulty; the location is inaccurate; and the problem such as come off easily is especially during some bigbore pipelines docking, because gasket seal is rubber material; soft, this phenomenon is particularly evident.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of PE pipe abutted flange, reaching convenient on-the-spot the installation, the gasket seal accurate positioning, does not allow caducous purpose.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of PE pipe abutted flange, comprise flange body, offer trapezoidal concave ring groove on the interface of described flange body, the bottom width of described concave ring groove is greater than the width of opening portion, be placed with the gasket seal of respective model on the described interface, the position corresponding with described concave ring groove is provided with trapezoidal bulge loop groove on the described gasket seal, and described bulge loop groove embeds in the described concave ring groove.
Preferably, be evenly distributed with 8 positioning holes on the described interface, construction bolt when being used for connecting.
Preferably, described concave ring groove and described bulge loop groove are respectively 1 circle.
Pass through technique scheme, be placed with gasket seal on the interface of the PE pipe abutted flange that the utility model provides, gasket seal embeds in the trapezoidal concave ring groove of flange body by trapezoidal bulge loop groove, connect closely, good airproof performance is not easy to leak, and carry gasket seal on the flange body, avoided at the scene the interim difficulty that gasket seal is installed in the installation process, accurate positioning, easy for installation.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art.
Fig. 1 is the flange body schematic representation of the disclosed a kind of PE pipe abutted flange of the utility model embodiment;
Fig. 2 is the gasket seal schematic representation on the disclosed a kind of PE pipe abutted flange of the utility model embodiment;
Fig. 3 is the concave ring groove of the disclosed a kind of PE pipe abutted flange of the utility model embodiment and the schematic cross-section of bulge loop groove interlocking.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described.
The utility model provides a kind of PE pipe abutted flange, and structural representation as shown in Figure 1 carries gasket seal on this PE pipe abutted flange, has avoided putting into when installing at the scene the difficulty of gasket seal, and is easy for installation, is not easy to come off.
Described PE pipe abutted flange, comprise flange body 1, offer trapezoidal concave ring groove 3 on the interface 2 of flange body 1, the width of concave ring groove 3 bottoms is greater than the width of opening portion, be placed with the gasket seal 4 of respective model on the interface 2, position corresponding with concave ring groove 3 on the gasket seal 4 is provided with trapezoidal bulge loop groove 5, and bulge loop groove 5 just in time embeds in the concave ring groove 3, as shown in Figure 3.
As can be seen from Figure 1, be evenly distributed with 8 positioning holes 6 on the interface 2, bolt is by tightening when being used for installing.
In the present embodiment, concave ring groove 3 and bulge loop groove 5 are respectively a circle, also can offer two circles or three circles etc., generally speaking, can reach requirement once enclosing, and gasket seal 4 just can closely be fixed on the flange body.
Be placed with gasket seal on the interface of the PE pipe abutted flange that the utility model provides, gasket seal embeds in the trapezoidal concave ring groove of flange body by trapezoidal bulge loop groove, connect closely, good airproof performance, be not easy to leak, and carry gasket seal on the flange body, avoided at the scene the interim difficulty that gasket seal is installed in the installation process, accurate positioning, easy for installation.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (3)
