Abstract
The utility model discloses a flange structure of a thrust-stop ring. The flange structure comprises a steel tube and a connecting flange sleeved outside the steel tube. The connecting flange is fixed and connected through match of a bolt and a nut. A ditch groove is formed in the outer side of an end port of the steel tube. A clamp groove matched with the ditch groove is formed in the connecting flange. The thrust-stop ring is arranged in a space formed by the stitch groove and the clamp groove. The flange structure of the thrust-stop ring has the advantages of being convenient to install, needless in welding, weld crack detection and the like when a pipeline is connected, suitable for being used for pipeline construction in an inflammable and explosive environment, and capable of bearing high pressure.
Description
Technical field
The utility model relates to the pipe connection system of welding/welding, mainly refers to the flanged connecting structure that need not to weld in the hydraulic pipe line connected system, thrust ring is supported.
Background technique
At present, usually hydraulic system pipeline adopts the welding pipeline, and jointing adopts Welded fitting or welding type flange, but this structure is carried out pipeline construction and often can be caused serious accident under inflammable, explosive environments.Because any welding pipeline can not be accomplished 100% flaw detection, and the weld joint is perishable, the weld seam sealing-off, pore etc. is arranged, be easy to cause the leakage of welding pipeline in addition.The unjointed flared pipeline linkage structure of available technology adopting can address the above problem, but this linkage structure high voltage performance is not enough.
The model utility content
The purpose of this utility model is to provide a kind of thrust ring flange arrangement, by thrust ring being positioned in the groove of pipe end, closely connect with the flange of guaranteeing to be fixed on the pipeline, overcome the deficiency in the conventional art, thereby realize the purpose of this utility model.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of thrust ring flange arrangement, comprise steel pipe and the adpting flange that is placed in the steel pipe outside, described adpting flange is connected and fixed by the bolt attaching nut, the outside of described port of steel pipe is processed with groove, described adpting flange is processed with the draw-in groove that matches with described groove, in the space that described groove and draw-in groove form a thrust ring is installed.
In an embodiment of the present utility model, the end face of described steel pipe joint is processed with groove, and described groove fit forms seal groove, is provided with Sealing in the described seal groove.
In an embodiment of the present utility model, the inwall of described steel pipe and the surface of Sealing are covered with anticorrosion layer.
In an embodiment of the present utility model, described groove is circular-arc band oblique angle structure, and the base angle of described draw-in groove is arc round angle.
In an embodiment of the present utility model, described thrust ring is the stainless steel spring circle.
The beneficial effects of the utility model are: easy for installation, need not welding, seam inspection etc. during connecting pipeline, and be applicable to the pipeline construction under inflammable, the explosive environments, and can bear high pressure.
Description of drawings
Fig. 1 is the schematic representation of thrust ring flange arrangement described in the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 1, a kind of thrust ring flange arrangement described in the utility model comprises that steel pipe 1 and 7, the outer cover in steel pipe 1 and 7 that needs connect have adpting flange 3, and adpting flange 3 is connected and fixed by bolt 2 attaching nuts 6.The outside at steel pipe 1 and 7 ports is processed with groove 9, and described adpting flange is processed with the draw-in groove 8 that matches with described groove 9, and groove 4 is circular-arc band oblique angle structure, and the base angle of draw-in groove 8 is arc round angle.In the space that groove and draw-in groove form a thrust ring 4 is installed, thrust ring 4 can be selected the stainless steel spring circle.By said structure design, thrust ring 4, adpting flange 3 and bolt 2 can absorption axes to pressure and impact.
In order to improve the sealability of said structure, fluted respectively in the end face processing of steel pipe 1 and 7 joints, two groove fit form seal groove, are provided with Sealing 5 in the seal groove.When in steel pipe 1 and 7 Fluid Flow in A being arranged, the pressure extrusion Sealing 5 of fluid, Sealing 5 distortion are full of the seal groove of steel pipe 1 and 7 joint end faces, thereby reach the purpose of sealing.
Only have steel pipe inner wall to contact medium in the pipe with Sealing 5 in the above-mentioned flanged connecting structure, if medium has corrosivity, then above-mentioned member needs resistant material or is covered with anticorrosion layer such as plastic-coated etc. on the surface, and adpting flange 3 is isolated with the interior working medium of pipe fully, therefore can not be corroded, prolong working life.
The thrust ring flange arrangement that the utility model provides not only guarantees easily without leaking, and is corrosion-resistant, impact resistance good; And can bear high pressure, ultrahigh pressure, Maximum operating pressure can reach 690bar, need not welding during installation, need not seam inspection etc., is applicable to the pipeline construction under inflammable, the explosive environments, and can bears high pressure, and is convenient during installation.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
