Abstract
The utility model relates to a kind of pipeline expander.The utility model comprises cylindrical tube, is fixed on the expansion oplate at cylindrical tube two ends, described two expansion oplate centers are respectively provided with a connecting tube, described connecting tube is greater than 5cm through the length L of expansion oplate internal surface, I shape gap is formed between two connecting tubes and cylindrical tube, described cylindrical tube radial direction is provided with drain pipe, and described drain pipe is provided with valve.It is simple that the utility model has structure, uses simple, the feature that the life-span is long.
Description
Technical field
The utility model relates to Cemented filling field, is specifically related to a kind of pipeline expander.
Background technique
When Cemented filling liquid or gas, because the temperature in the external world is changing always, pipeline is situation that is elongated or that shorten because the reason of expanding with heat and contract with cold there will be, so pipeline can be arranged " S " type in certain length or install slip joint when Pipe installing, " S " type pipeline makes pipeline become huge, floor space becomes large, is inconvenient to use; Slip joint material generally uses polythene material to make, and working life is short, needs often to change.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of long service life, the pipeline expander that structure is simply firm.
The utility model adopts following technological scheme to realize: the utility model comprises cylindrical tube, is fixed on the expansion oplate at cylindrical tube two ends, two described expansion oplate centers are respectively provided with a connecting tube, described connecting tube is greater than 5cm through the length L of expansion oplate internal surface, I shape gap is formed between two connecting tubes and cylindrical tube, described cylindrical tube radial direction is provided with drain pipe, and described drain pipe is provided with valve.
The utility model is further improved, and the Placement of described cylindrical tube and connecting tube and expansion oplate is for welding.
The utility model is further improved, and the outside diameter D of described cylindrical tube equals 2 times of described connecting tube exradius d, and the length b of described cylindrical tube equals connecting tube outside diameter d.
The beneficial effect adopting technique scheme to produce is:
The utility model is by being arranged on the expansion oplate in cylindrical tube, when conveyance conduit expands with heat and contract with cold distortion, conveyance conduit can be avoided to break or spalling by the distortion of expansion oplate, connecting tube is greater than 5cm through the length L of expansion oplate internal surface, can ensure that connecting tube can not split away off from expansion oplate like this, the utility model cylindrical tube radial direction is provided with drain pipe, can timing purging line in impurity.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model;
Fig. 2 is sectional view of the present utility model;
1. cylindrical tube 2. connecting tube 3. drain pipe 4. valve 5. expansion oplate 501. expansion oplate internal surface.
Embodiment
As shown in Figure 1, the utility model comprises cylindrical tube 1, be fixed on the expansion oplate 5 at cylindrical tube two ends, described expansion oplate 5 center is provided with connecting tube 2, the Placement of described cylindrical tube 1 and connecting tube 2 and expansion oplate 5 is for welding, described cylindrical tube 1 radial direction is provided with drain pipe 3, described drain pipe 3 is provided with valve 4, have a lot of impurity in conveyance conduit and flow into cylindrical tube 1, arranging drain pipe 3 can periodical blowdown, described connecting tube 2 is greater than 5cm through the length L of expansion oplate 5 internal surface 501, when preventing expansion oplate 5 to be out of shape excessive, connecting tube 2 and expansion oplate 5 come off, the outside diameter D of described cylindrical tube 1 equals 2 times of described connecting tube 2 exradius d, the length b of described cylindrical tube 1 equals connecting tube 2 outside diameter d, if the ratio of D/d is too small, be easy to cause expansion oplate 2 expansion coefficient to cause expansion oplate to rupture not, if the ratio of D/d is crossed conference and is caused waste of material, according to practical effect, work as D/d=2, during d=b, effect is best.
When using the utility model, at conveyance conduit, this device is just set every a segment distance, conveyance conduit by welding or the form of flange plate and connecting tube 2 to connecting.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
