Not only it have impact on pipe insulation effect but also brought inconvenience for the trouble-free operation of unit.
Pipe insulation typically uses the heat preservation method of heat-preservation cotton+color steel, and outer casing junction is overlapped using single reinforcement mostly,
Facts have proved no matter construction process control it is good again, the vibrations of pipeline, stretching can all cause insulation outer casing to loosen, disconnect, no
The demand of actual use can be met.
Utility model content
The purpose of this utility model is that there is provided a kind of pipe insulation outer casing is positive and negative to overcome above-mentioned the deficiencies in the prior art
Double muscle overlap mounting structures, outer casing using the double button overlap joints of the double muscle of concavo-convex muscle, can effectively solve outer casing loosen, lacking of disconnecting
Fall into, and the double muscle of concavo-convex muscle be overlapped with it is straight beneficial to pipeline outer casing.
To achieve the above object, the utility model uses following technical proposals：
Positive and negative pair of muscle overlap joint mounting structure of pipe insulation outer casing, including the heat-insulation layer outside heat distribution pipeline is placed on, it is described
More piece outer casing is cased with outside heat-insulation layer, adjacent outer casing is overlapping to be set, and often saves outer casing end circumferentially arranged multiple recessed
Muscle and multiple convex tendons, the concave bar of adjacent outer casing fasten snapping, and the convex tendon of adjacent outer casing fastens snapping.
It is preferred that, the quantity for often saving concave bar that the outer casing end sets and convex tendon is equal.
It is preferred that, the concave bar and convex tendon for often saving the outer casing end are uniformly laid along outer casing is circumferential.
It is preferred that, the multiple convex tendons for often saving the outer casing are located on same first annulus of outer casing, often save described outer
Multiple concave bars of backplate are located on same second annulus of outer casing.
First annulus and the second annulus are separated by setpoint distance.
Concave bar position on convex tendon and the second annulus on first annulus is corresponded.
It is preferred that, the circumferentially arranged fastener between the concave bar and convex tendon of the outer casing.
The beneficial effects of the utility model are：
The utility model sets the double button overlap joints of the double muscle of concavo-convex muscle on outer casing, strengthens the connection of pipe insulation outer casing strong
Degree, increases the straight property of pipeline, it is to avoid outer casing stretching, disconnection, deformation caused by the reasons such as pipe vibration, expansion.
The utility model sets the form of concavo-convex muscle, when outer casing is overlapping can quick capturing position, to a certain extent
Simplify when ductboards duct is installed it is levelling, look for straight process, it is easy to operate, install simple.
The utility model can both strengthen the bulk strength of ductboards duct, can also strengthen the local strong of adjacent tubes section faying face
Degree, mitigates backplate crimp of the heat distribution pipeline caused by activity for a long time, extends backplate service life, be particularly suitable for use in thermoelectricity
Factory's big-diameter pipeline insulation, it is easy to promote, with preferable economic benefit and social benefit.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, 1- heat distribution pipelines；2- heat-insulation layers；3- pipeline outer casings；4- concave bars；5- convex tendons.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in figure 1, positive and negative pair of muscle overlap joint mounting structure of pipe insulation outer casing, including be placed on outside heat distribution pipeline 1
More piece pipeline outer casing 3 is cased with outside heat-insulation layer 2, heat-insulation layer 2, adjacent channel outer casing 3 is overlapping to be set, per length of tubing outer casing
The circumferentially arranged multiple concave bars 4 in 3 ends and multiple convex tendons 5, the concave bar 4 of adjacent channel outer casing 3 fasten snapping, adjacent tubes
The convex tendon 5 of road outer casing 3 fastens snapping.
The concave bar 4 set per the end of length of tubing outer casing 3 is equal with the quantity of convex tendon 5.
Concave bar 4 and convex tendon 5 per the end of length of tubing outer casing 3 are uniformly laid along pipeline outer casing 3 is circumferential.Pipeline outer casing
3 concave bar 4 and convex tendon 5 is all circumferentially uniformly arranged, and the concave bar and convex tendon on many length of tubing outer casings 3 use same way cloth
If more rapidly facilitating when adjacent channel outer casing 3 is connected.
Multiple convex tendons 5 per length of tubing outer casing 3 are located on same first annulus of pipeline outer casing 3, outside every length of tubing
Multiple concave bars 4 of backplate 3 are located on same second annulus of pipeline outer casing 3.First annulus and the second annulus be separated by setting away from
From.The position of concave bar 4 on the annulus of convex tendon 5 and second on first annulus is corresponded.The concave bar 4 and convex tendon 5 of pipeline outer casing 3
Between gap is set, when adjacent channel outer casing 3 is connected, convex tendon and convex tendon coordinate, and concave bar and concave bar coordinate, so just can be real
Existing dual snapping, adjacent channel outer casing 3 connects more reliable.And by the concave bar on every length of tubing outer casing 3 and convex tendon
Position is corresponded, more simple and convenient when manufacturing pipeline outer casing 3, also can when adjacent channel outer casing 3 is connected
Rapid matching, goes to be directed at convex tendon again, saves the time without being aligned after concave bar.
The circumferentially arranged fastener between the concave bar 4 and convex tendon 5 of pipeline outer casing 3, fastener can select screw.
Single-unit pipeline outer casing 3 is adjacent to pipe insulating layer 2 during installation, then by the adjacent port of length of tubing outer casing 3
Concave bar and convex tendon be pressed on the concave bar and convex tendon of adjacent length of tubing outer casing 3, after the completion of connection in adjacent concave bar and convex tendon
Between circumferentially play screw, the lap-joint of 2-section pipe road outer casing 3 is buckled well.Due to using concavo-convex double muscle overlap joints, outer casing lap-joint
It is firmly combined with being difficult activity for positive and negative button, and because 2 points of principles for fixing line always can ensure the straight of lap-joint, it is to avoid
During single reinforcement overlap joint pipeline easily activity the problem of, save the engineering time, therefore protected outside the pipelines using concavo-convex double double button connections of muscle
Plate 3, can simplify the process of levelling capturing when mounted, the concavo-convex muscle of pipeline outer casing 3 is overlapping buckle well can directly stamp axially and
Ring screw, ring screw nailing position is in the centre position of outer casing lap-joint.
When heat distribution pipeline shakes larger or pipe diameter more than 500mm, it should suitably increase the concave bar of pipeline outer casing 3 and convex tendon
Between overlap distance.
It is not new to this practicality although above-mentioned embodiment of the present utility model is described with reference to accompanying drawing
The limitation of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel need not pay the various modifications that creative work can make or deform still in protection model of the present utility model
Within enclosing.
