Abstract
The connection for engineering pipelines generally adopts three manners including welding connection, pipe joint connection and flange connection. The utility model provides a simple, reliable and low-cost connecting structure for the pipelines, which enables the connection of the pipelines to be more convenient. The connecting structure includes loose flanges, fastening bolts, a seal gasket and two connecting pipes, wherein end parts of the two connecting pipes are provided with turned-over edges, the turned-over edges are vertical to the pipe walls, the loose flanges are sleeved on the outer edges at the end parts of corresponding connecting pipes, the seal gasket is arranged between the turned-over edges of the two connecting pipes, at least three bolts are arranged on the periphery of each loose flange, and the loose flanges are compressed tightly on the back sides of the turned-over edges of the corresponding connecting pipes so as to connect the pipes together.
Description
Technical field:
The present invention relates to a kind of linkage structure of pipeline.
Background technique:
The connection of pipe-work generally adopts welding, pipe joint connection to be connected three kinds of modes with flange.Flange connects and to have reliable operation, simple load and unload advantage, and existing flange connects generally in the pipe end welding or casts out flange, and it is high to make required precision, and process is many.CN101153680 discloses a kind of linkage structure of delivery pipe, and connected pipeline port is provided with flange, links together through spill flange, convex flange, clamping bolt and seal ring; This linkage structure has and connects characteristics quick, good seal performance, has higher compressive strength, still; The spill flange that adopts and the structure of convex flange are still complicated, and manufacture cost is higher, simultaneously; Flange needs be enclosed within behind the flange on the outer of pipeline again; No matter be spill flange or convex flange, form, increased the difficulty that pipeline connects by at least 2 parts.
Summary of the invention:
The present invention provides a kind of more simple and reliable, pipeline jointing construction that cost is lower, and a kind of method for flanging of connecting tube is provided, and makes the pipeline behind the flange connect more convenient.
The present invention includes loose flange, clamping bolt, sealing gasket and 2 connecting tubes; 2 connecting tube ends are equipped with flange, and flange is vertical with tube wall, and loose flange is enclosed within the outer of connecting tube end separately; Be provided with sealing gasket between the flange of two connecting tubes; At least be provided with 3 bolts on the circumference of loose flange, loose flange is pressed on the back side of connecting tube flange separately by bolt, thereby pipeline is joined together.
Loose flange is the integral planar plate-type flange.
The production method of flange:
The first step: drive the connecting tube rotation;
Second step: the connecting tube end of flange is intended in heating, makes the end material reach softening temperature, and for steel pipe, heating-up temperature is 800～900 ℃;
The 3rd step: two taper spinning heads that sense of rotation is opposite stretch into pipe end inside, and first spinning head is processed 45 ° of flange with pipe end, and second spinning head is further processed 90 ° of flange with pipe end;
The 4th step: like need the other end of connecting tube is carried out flange, then on connecting tube, be inserted in earlier two movable flanges, accomplish the flange of the other end by the first step～method in 3rd step again.
The present invention utilizes tubing itself to carry out flange, forms sealing surface, has simplified mounting structure, has reduced materials consumption, and pipeline connects simple, installs fast, and accelerating construction progress has been practiced thrift the man power and material effectively.
Description of drawings:
Fig. 1 is the schematic representation of pipeline jointing construction of the present invention.
Fig. 2 is a flanged edge making method schematic representation.
Fig. 3 is the deformation schematic representation of turn-up process.
Embodiment:
As shown in Figure 1; A kind of pipeline structure that connects through flat flange; Comprise connecting tube 1, flat flange 2, sealing gasket 3, flat flange 4, clamping bolt 5 and connecting tube 6, flat flange 2 is actively socketed on respectively on the outer wall of connecting tube 1 and connecting tube 6 with flat flange 4; Connecting tube 1 is respectively equipped with flange 101 and flange 601 with connecting tube 6, and flange is vertical with separately tube wall respectively, also is provided with sealing gasket 3 between two flange; Flat flange 2 is linked together by the bolt 5 in same circle distribution with flat flange 4, and is pressed on the back side of flange 101 and flange 601, and connecting tube 1 and connecting tube 6 are closely linked together; The quantity of bolt be 3 or more than, on same circumference, evenly distribute.
Like Fig. 2, shown in Figure 3, drive connecting tube 1 around self axle center rotation, the end of 9 pairs of connecting tubes 1 of heating equipment heating simultaneously, heating-up temperature is 800～900 ℃, makes steel connecting tube end material softening, heating equipment can adopt flame or electromagnetic mode heating; First spinning head 7 and second spinning head 8 have certain rotating speed and sense of rotation opposite; Can avoid in the spinning turn-up process connecting tube end material being pushed along same direction; First spinning head 7 and second spinning head 8 can be along the axial and radial motions of connecting tube; Make two spinning heads be close to the end material of connecting tube, first spinning head 7 is processed 45 ° of flange with pipe end, and second spinning head 8 is further processed 90 ° of flange with pipe end; Like need the other end of connecting tube 1 is carried out flange, then on connecting tube 1, be inserted in earlier two flat flanges, accomplish the flange of the other end again by above-mentioned steps.
Claims (2)
1. the linkage structure of a pipeline; Comprise loose flange, clamping bolt, sealing gasket and 2 connecting tubes, it is characterized in that: said 2 connecting tube ends are equipped with flange, and flange is vertical with tube wall; Loose flange is enclosed within the outer of connecting tube end separately; Be provided with sealing gasket between the flange of two connecting tubes, be provided with 3 bolts on the circumference of loose flange at least, loose flange is pressed on the back side of connecting tube flange separately by bolt.
2. a kind of pipeline jointing construction according to claim 1 is characterized in that: said loose flange is the integral planar plate-type flange.
