Description
Technical field
The utility model relates to feed pipe fields, more particularly to a kind of water supply PVC-U with support warning device
Double straight tubes.
Background technique
Water supply is usually used in prefabricated direct-buried thermal insulation pipe system with PVC straight tube, foam filled between service pipe and outer protection tube
Polyurethane insulation coating
For the damaged leakage problems that prefabricated direct-buried thermal insulation pipe is likely to occur, it is typically employed in polyurethane insulation coating and is arranged
Alarming line is alarmed, and when pipeline leakage, judges dangerous situation position, guidance repairing work by monitoring system.In the prior art
For the processing method of alarming line, a perforated device is set usually on internal service pipe, alarming line is allowed to wear from hole
It crosses, this method is too simple, and alarming line lacks more stable fixation, in the system in particular for double work pipeline, needs to allow
The combination of alarming line and service pipe is more reliable.
In addition, need to fix service pipe in advance to make the thickness of polyurethane insulation coating as uniform as possible, because
And it needs that the additional fixed structure for being used to support service pipe is arranged.
It can be kept with one heart in the stable polyurethane insulation coating in outer protection tube road therefore, it is necessary to a kind of, and report can be facilitated
The fixed water supply bis- straight tubes of PVC of alert line.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide one kind to have support alarm
The water supply of the device bis- straight tubes of PVC-U.
In order to solve the above technical problems, the utility model provide it is a kind of with support warning device water supply it is bis- with PVC-U
Straight tube, which is characterized in that the PVC-U straight tube including the setting of two side by side parallel, the roughness of the PVC-U straight tube are 0.0081-
0.0089, the nominal outside diameter De of the PVU-U straight tube are 75-200, and nominal pressure Pn is 0.6-2.5MPa, two PVC-U
Straight tube is connected by support warning device, and the support warning device includes two identical support units, the support unit
It is socketed on PVC-U straight tube by straight tube hole, at least one alarm string holes, the support unit is additionally provided on the support unit
On be additionally provided at least one for disposing card slot of alarming line, described two support units are connected by fixed part.
There are 2 alarm string holes and 2 card slots on each support unit.
The support unit is elongated, and 2 alarms string holes is respectively arranged on the two sides of support unit, 2 cards
Slot is respectively arranged on the both ends of support unit.
The material of the support unit is high density PVC-U, and the fixed part is elastic fixed part.
One end of the PVC-U straight tube is equipped with elastic seal ring.
The PVC-U straight tube is one injection molding
The utility model is achieved the utility model has the advantages that incorporating the fixation device of alarming line and supporting water supply PVC-U bis-
The fixed structure of straight tube, compact structure, reliable performance are adaptable.
Detailed description of the invention
Fig. 1 is the structure diagram of the exemplary embodiment of the utility model；
Fig. 2 is the structure diagram of the support warning device of the utility model.
Specific embodiment
The utility model is further described with exemplary embodiment with reference to the accompanying drawing:
A kind of water supply bis- straight tubes of PVC-U with support warning device as shown in Figure 1, which is characterized in that including two
The one injection of side by side parallel setting forms PVC-U straight tube 7, and one end of the PVC-U straight tube is equipped with elastic seal ring 8, just
In more firm connection, two PVC-U straight tubes are connected by support warning device, and more compact structure is stablized, it is easier to tie up
Concentric is held, the support warning device (as shown in Figure 2) includes two identical support units 1, and the support unit is in
The internal diameter of strip, size and outer protection tube 6 matches, and for PVC-U straight tube to be fixed, the material of the support unit is
High density PVC-U, it was not only light but also reliable to compare other materials, and the support unit is socketed in PVC-U straight tube by straight tube hole 2
On, there are 2 alarm string holes 3 and 2 for being respectively arranged on two sides to be set to alarming for disposing for both ends on each support unit
The card slot 4 of line, it has not been convenient to which the alarming line across alarm string holes can be embedded in card slot, and described two support units are solid by elasticity
Determine portion 5 to be connected, elastic fixed part enables entirely warning device to be supported to deal with a degree of deformation, more adaptable.
The specification of the PVC-U straight tube can be that nominal outside diameter De is 75-200, and nominal pressure Pn is 0.6-2.5MPa.Under
Table is the preferred specifications parameter of PVC-U straight tube:
The utility model is mainly used for providing a kind of water supply bis- straight tubes of PVC-U with support warning device, incorporates
The fixation device of alarming line and the fixed structure of the support water supply bis- straight tubes of PVC-U, compact structure, reliable performance are adaptable.
Above embodiments do not limit the utility model in any way, all to be done in a manner of equivalent transformation to above embodiments
Other improvement and application out, belong to the protection scope of the utility model.
