Abstract
For the flange connection at pipe interface place, comprise the flange being arranged at two body interface end to be connected respectively, flange is placed on the outer wall of body to be connected respectively, and flange is connected and fixed by bolt attaching nut; On the outer wall of body interface end, symmetry has the groove be parallel to each other, and groove take pipe diameter as the both sides that symmetry axis is opened in body, and the two ends of groove are connected with the outside of body; The through hole be connected with the outside of flange is offered at the inwall of the flange corresponding with groove, make when flange is placed on the interface end of body, formed between through hole with groove and be connected and the straight passage closed up and down with the external world, the clamping part of U-shaped pin is respectively through in straight passage.In the straight passage that the utility model mainly utilizes the through hole of the groove and flange inner wall that U-shaped pin is placed in tube wall to be formed, to guarantee that pipe is fixed on the flange compact siro spinning technology on pipeline, realize the object without the need to welding, seam inspection.
Description
Technical field
The utility model relates to pipeline jointing construction, especially in fluid pressure line connects for the flange connection at pipeline connecting interface place.
Background technology
Flange is various kinds of equipment, pipeline connect in the most frequently used a kind of pipeline fittings arrived, pipeline connect in there is extremely important effect.Usually in hydraulic system pipeline, adopt welding pipeline, interface adopts socket-welding fitting or welded type flange, but this structure is carried out pipeline construction and often can be caused major accident under inflammable, explosive environments.Because welding pipeline can not accomplish 100% flaw detection, easily becoming rusty in commissure, the easy sealing-off of weld seam, has pore etc., all can cause the leakage of pipeline.Although adopt unjointed flared pipeline syndeton to solve the problem in the prior art, this structure cannot bear high pressure.
Summary of the invention
The purpose of this utility model be to provide a kind of structure simple, without the need to welding and seam inspection, be applicable to construction under inflammable and explosive environment and the flange connection for pipe interface place of high pressure can be born.
The utility model solves the technical scheme that prior art problem adopts: a kind of flange connection for pipe interface place, comprise the flange being arranged at two body interface end to be connected respectively, described flange is placed on the outer wall of body to be connected respectively, and described flange is connected and fixed by bolt attaching nut; On the outer wall of described body interface end, symmetry has the groove be parallel to each other, and described groove take pipe diameter as the both sides that symmetry axis is opened in body, and the two ends of groove are connected with the outside of body; The through hole be connected with the outside of flange is offered at the inwall of the flange corresponding with groove, make when flange is placed on the interface end of body, formed between through hole with groove and be connected and the straight passage closed up and down with the external world, the clamping part of U-shaped pin is respectively through in straight passage.
The outer wall of arbitrary described body interface end has the seal groove perpendicular with the interface surface of to be connected two bodys, and seal groove is built-in with seal.
The beneficial effects of the utility model are: in the straight passage that the utility model structure is simple, easy for installation, it mainly utilizes the passage of the groove and flange inner wall that U-shaped pin is placed in tube wall to be formed, to guarantee that pipe is fixed on the flange compact siro spinning technology on pipeline, thus the object realized without the need to welding, seam inspection, therefore this structure is particularly useful for the pipeline construction under inflammable, explosive environments, and can bear high pressure.The effect of fitted seal groove, makes the utility model ensure the sealing of docking body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the profile of the straight channel part of Fig. 1.
In figure: 1-body, 2-bolt, 3-flange, 4-U shape pin, 5-seal, 6-seal groove, 7-through hole, 8-is straight passage, 9-nut, 10-groove.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described:
Fig. 1 is the structural representation of a kind of flange connection for pipe interface place of the utility model.For the flange connection at pipe interface place, comprise the flange 3 being arranged at two body 1 interface end to be connected respectively, flange 3 is placed on the outer wall of body 1 to be connected respectively, and flange 3 is connected and fixed by bolt 2 attaching nut 9; As shown in Figure 2, symmetrically on the outer wall of body 1 interface end have the groove 10 be parallel to each other, groove 10 is with the diameter of body for symmetry axis is opened in the both sides of body 1, and the two ends of groove 10 are connected with body 1 outside; The through hole 7 be connected with flange 3 outside is offered at the inwall of the flange 3 corresponding with groove 10, and make when flange 3 is placed on body 1 interface end, formed between through hole 7 with groove 10 and be connected and the straight passage 8 closed up and down with the external world, the clamping part of U-shaped pin 4 is respectively through in straight passage 8.Such structure can make U-shaped pin 4, flange 3 and bolt 2 can the better pressure of absorption tube inner fluid and impulsive force.
In order to improve the sealing of body, the outer wall of arbitrary body 1 interface end has the seal groove 6 perpendicular with the interface surface of to be connected two bodys 1, and seal groove 6 is built-in with seal 5.When having fluid to flow in the body 1 after docking, the pressure meeting squeeze sealing member 5 of fluid, makes seal 5 be out of shape the seal groove being full of body 1 joint end face, thus reaches the object of sealing.
In flange connection of the present utility model, the inwall of body 1 is only had to contact medium in pipe with seal 5, if medium has corrosivity, then above-mentioned component needs resistant material or is covered with corrosion-resistant finishes etc. on surface, and adpting flange 3 is complete and medium is isolated, therefore can not be corroded, thus extend service life of the present utility model.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
