Abstract
The utility model discloses a joint device of a spiral corrugated pipe, which comprises a hoop, a rubber sleeve and a rubber plate. A spiral groove is arranged on the inner wall of the rubber sleeve, the screw pitch of the spiral groove is identical to that of the spiral corrugated pipe, the rubber plate is arranged on the outer side of the rubber sleeve, and the rubber plate and the rubber sleeve are placed in the hoop. The joint device of the spiral corrugated pipe has the advantages of simple structure, convenience in installation and maintenance, low cost and fine sealing property, and a joint has a good axial pull loosening preventive performance, and can have certain angular displacement.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of piecing devices of helical corrugation pipeline.
Background technique
Often adopt the helical corrugation pipeline in present combustion gas, chemical industry, the aqueduct.Placement commonly used has heat-shrinkable tube (band) connection, the connection of " Hough cover " formula, the connection of electric smelting band etc., and these connections exist connection set and make deficiencies such as complicated, that connection is bothersome, sealing is poor, reusability is bad.
Existing clamp band type pipe coupling; Though have installation, advantage easy to maintenance; But also there is certain defective,, all need on pipeline, processes groove like patent CN 201259040Y improved groove type pipeline jointing clip and patent CN 101614309A groove clamping hoop type pipeline joint; Have the shortcoming that structure is complicated, cost is high, and also be not suitable for the connection of helical corrugation pipeline; On the market wedge, the clamp band type pipe coupling of Y-shaped ring structure for another example; Only be applicable to the pipeline of plain tube structure; Its axial taking off property of tension is also bad; Pipeline junction can not have any bending, otherwise can cause poor sealing, and is inappropriate for being tightly connected of helical corrugation pipeline of surface irregularity.
Summary of the invention
Connect the above-mentioned technical problem that exists in order to solve existing helical corrugation pipeline, the utility model provides the piecing devices of a kind of simple in structure, good airproof performance, helical corrugation pipeline convenient for installation and maintenance.
The technological scheme that the utility model solves the problems of the technologies described above employing is: it comprises clip, rubber sleeve and rubber plate; The cross section of rubber sleeve is a rectangular; The rubber sleeve inwall is provided with spiral chute; Spiral fluted pitch is identical with the pitch of helical bellows, and the rubber sleeve outside is provided with rubber plate, and rubber plate, rubber sleeve place in the clip.
In the piecing devices of above-mentioned helical corrugation pipeline, also be provided with arc plate, arc plate is located at the hoop mouth of clip, and the internal diameter of arc plate is identical with the internal diameter of clip body, and it is inboard that an end of arc plate is welded on the clip body.
In the piecing devices of above-mentioned helical corrugation pipeline, the termination of said clip is provided with baffle plate.
The technique effect of the utility model is: 1) the utility model adopts the rubber sleeve of helical bellows screw-in to be enclosed within on the helical bellows that will connect; The skin of rubber sleeve is provided with rubber plate; Realize being tightly connected with clip extruding rubber plate again; Owing to all be the sealing that rubber extruded realizes, connect good seal performance.2) the clip two ends of the utility model are provided with baffle arrangement; It is good that the pipeline axial tension is taken off performance; And between the two helical corrugation pipeline terminations certain clearance is arranged, and adopt the rubber-like rubber seal, make interconnective pipeline that certain angular displacement can be arranged; Be convenient to constructing operation, and guarantee good sealing property.3) simple in structure, the easy processing of the utility model, low, the good airproof performance of cost are installed, easy to maintenance.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Fig. 2 is the sectional view of the utility model along A-A line among Fig. 1.
Embodiment
Shown in accompanying drawing 1, the utility model comprises clip 3, rubber sleeve 1 and rubber plate 2, and the cross section of rubber sleeve 1 is a rectangular.The inwall of rubber sleeve 1 is provided with spiral chute, and the outside of rubber sleeve 1 is provided with rubber plate 2, and rubber plate 2, rubber sleeve 1 place in the clip 3, and the termination of clip 3 is provided with baffle plate 3-3, and baffle plate 3-3 contacts with rubber sleeve 1 termination.
As shown in Figure 2; Clip 3 comprises clip body 3-1 and arc plate 3-2, and arc plate 3-2 is located at the hoop mouth, and the internal diameter of arc plate 3-2 is identical with the internal diameter of clip body 3-1; It is inboard that the end of arc plate 3-2 is welded on clip body 3-1, and arc plate 3-2 can block the hoop mouth during clip body banding.
During use, rubber sleeve 1 is screwed in two helical corrugation pipeline terminations to be connected, then clip 3 is opened; Rubber plate 2 is placed in the clip 3; Clip 3 is sleeved on the outside of two rubber sleeves 1, with clip 3 bandings, the baffle plate 3-3 of clip 3 contacts with the termination of rubber sleeve 1 with bolt 4 again; Baffle plate 3-3 on the clip 3 can improve axial anti-the drawing property of taking off of pipeline junction greatly, and rubber plate 2 contacts and can improve the sealability of pipe coupling with the extruding of rubber sleeve 1, clip 3.
