Abstract
The utility model relates to a kind of combined double-skin duct link, mainly solves the problem that in prior art, not prison welding is solid, Security is not high.The utility model, by adopting a kind of combined double-skin duct link, comprises the first pipe fitting and the second pipe fitting, and described first pipe fitting comprises conduction copper column, the first outer layer sleeve link, first horn-likely stretches out annulus, inner layer pipe link and through hole; Described second pipe fitting comprises second and horn-likely stretches out annulus and the second outer layer sleeve link; One end that first outer layer sleeve link is little with the first horn-like diameter stretching out annulus is connected, inner layer pipe link be positioned at first horn-like stretch out annulus and with the first outer layer sleeve link, attachment portion is provided with through hole, second horn-likely stretches out the technological scheme that the little one end of circle diameter is connected with the second outer layer sleeve link and solves the problems referred to above preferably, can be used for during double-skin duct connects.
Description
Technical field
The utility model relates to a kind of combined double-skin duct link.
Background technique
Along with the raising of national environmental standard, require more and more higher to the environmental-protecting performance of equipment In Oil Service Station.Recently, to be quarantined " gas station oozes, leakage pollution control criterion (exposure draft) " regulation that general bureau writes by the quality supervision and test of national environmental protection portion: newly-built, renovating and enlarging gas station underground oil pipeline should select the double pipeline with second protection space or individual layer petroleum pipeline to install antiseepage sleeve pipe additional.The second protection space of each double pipeline system should be all through and can carry out leak detection (monitoring).Therefore thermoplastic double-skin duct is applied to gas station's controlling methodology of oil pipeline and becomes inexorable trend.
CN201310530675.2 relates to a kind of connector for the double-deck covering pipeline floated being fixed to structure, this connector comprises the device for being fixed to structure, and the longitudinal axis around connector also comprises the outer body forming outer channel manages with being formed in internal channel, the feature of this connector is, it comprises longitudinal axis being fixedly connected with by the support that is slidably connected along connector for the device being fixed to structure, and this connector comprises and keeps track for generation of at least one aperture be fixedly connected with for generation of at least one being slidably connected.
Thermoplastic double-skin duct needs to make the interlayer gap between internal layer main pipeline and outer layer sleeve keep being open to traffic, thus proposes higher requirement to the connecting-piece structure of double-skin duct.
Model utility content
Technical problem to be solved in the utility model is the problem that in prior art, not prison welding is solid, Security is not high, provides a kind of combined double-skin duct link newly.This link is used for during double-skin duct connects, having the advantage that firm welding, Security are high.
For solving the problem, the technical solution adopted in the utility model is as follows: a kind of combined double-skin duct link, it is characterized in that comprising the first pipe fitting and the second pipe fitting, described first pipe fitting comprises conduction copper column, the first outer layer sleeve link, first horn-likely stretches out annulus, inner layer pipe link and through hole; Described second pipe fitting comprises second and horn-likely stretches out annulus and the second outer layer sleeve link; One end that first outer layer sleeve link is little with the first horn-like diameter stretching out annulus is connected, inner layer pipe link be positioned at first horn-like stretch out annulus and with the first outer layer sleeve link, attachment portion is provided with through hole, and second horn-like little one end of circle diameter of stretching out is connected with the second outer layer sleeve link.
In technique scheme, preferably, described conduction copper column is located at the first outer layer sleeve link, inner layer pipe link, second horn-likely stretches out on annulus and the second outer layer sleeve link.
In technique scheme, preferably, the first horn-like annulus and second that stretches out horn-likely stretches out the larger one end equal diameters of circle diameter, and during welding, the first horn-like annulus that stretches out is connected with the second horn-like annulus that stretches out.
Assembled two-layer pipe joint described in the utility model, is made up of the first pipe fitting and the second pipe fitting, can realize the connection of the first pipe fitting and inside and outside layer sleeve pipe, the connection of the second pipe fitting and outer layer sleeve and the connection between the first pipe fitting and the second pipe fitting.This double-skin duct link is combined, can respectively with the welding of internal layer main pipeline and outer layer sleeve, thus ensure the reliability of welding.Pipe fitting has and stretches out annulus in horn-like, thus makes pipe fitting internal layer and outer interlayer have larger space, occurs interfering when avoiding internal layer main pipeline to weld.Pipe fitting mezzanine space is comparatively large, if internal layer main pipeline leaks, is convenient to the circulation of medium, achieves good technique effect.

Embodiment
[embodiment 1]
A kind of combined double-skin duct link, as shown in figures 1-4, comprises the first pipe fitting and the second pipe fitting, and described first pipe fitting comprises conduction copper column, the first outer layer sleeve link, first horn-likely stretches out annulus, inner layer pipe link and through hole; Described second pipe fitting comprises second and horn-likely stretches out annulus and the second outer layer sleeve link; One end that first outer layer sleeve link is little with the first horn-like diameter stretching out annulus is connected, inner layer pipe link be positioned at first horn-like stretch out annulus and with the first outer layer sleeve link, attachment portion is provided with through hole, and second horn-like little one end of circle diameter of stretching out is connected with the second outer layer sleeve link.
As shown in Figure 5, when being connected with double-skin duct, first internal layer main pipeline is inserted inner layer pipe link, then to the conduction copper column energising on internal layer pipe joint, by hot melting way, internal layer main pipeline is connected with inner layer pipe link, then the annulus on the annulus on the second pipe fitting and the first pipe fitting is fitted, and to the conduction copper column energising on annulus, make its firm welding, and then respectively outer layer sleeve is inserted the outer layer sleeve link at two ends, and hot melting way is adopted to make outer layer sleeve and combined pipe pipe connecting firm welding.
