Description
Technical field
The present invention relates to a kind of blind plate, specifically, is a kind of PE pipeline pressure test blind plate.
Background technique
Along with the development in city, the a large amount of pressure piping for water supply and sewage work of PE pipeline, for pressure piping, its intensity and air tightness test are even more important, and intensity and hermeticity experiment basic operation are: after PE pressure piping has been constructed, pipe section pressure test, welding closure plate, installation testing utensil, bath, exhaust, pressurization, leak detection etc.As PE plug is taked in pressure testing termination, enough large working pit need be left, be convenient to welding machine sweat soldering.Plug before the test rear dismounting is very inconvenient, especially (when being greater than 1km, segmentation is needed) during duct segments pressure testing, it is very large that adjacent two segment pipes after pressure testing connect difficulty, and whether seepage after connecting, cannot be detected, just affect the normal usage function of pipeline as there is seepage, the difficulty of later period maintenance is also very large.
Therefore PE plug is used to there is above-mentioned all inconvenience and problem in known PE pipeline pressure test.
Summary of the invention
Object of the present invention, be to propose one with low cost, structure is simple, easy and simple to handle, can ensure again the PE pipeline pressure test blind plate of pipeline normal usage function.
For achieving the above object, technical solution of the present invention is:
A kind of PE pipeline pressure test blind plate, PE pipe head is provided with PE pipeline flanges, comprises steel blind plate, steel flanges sheet, and a gasket seal and outlet valve, is characterized in that:
Described steel blind plate is a circular steel plate, at the equally spaced bolt hole of its edge placement and waterstop, is provided with a through hole in the middle part of it, is welded with a steel short tube in through hole, and steel short tube two ends are with internal thread;
Described steel flanges sheet arranges and treats with bolt, steel flanges sheet to be connected the bolt hole that pressure testing PE pipeline flanges matches with described steel blind plate, and by the clamping of PE pipeline flanges steel flanges sheet therebetween;
There is provided a gasket seal, so that liner is at steel blind plate and treat between pressure testing PE pipeline flanges;
Described outlet valve is assemblied on steel short tube one end.
PE pipeline pressure test blind plate of the present invention can also be further achieved by the following technical measures.
Aforesaid PE pipeline pressure test blind plate, wherein said bolt can according to its intensity of the pressure selection of water supply and sewerage pipeline and diameter.
Aforesaid PE pipeline pressure test blind plate, wherein said steel short tube is that inside nominal diameter is at DN15 ~ DN25.
After adopting technique scheme, PE pipeline pressure test blind plate of the present invention has the following advantages:
1, with low cost, structure is simple, easy to make;
2, simplify PE pipeline pressure test operation, be convenient to operative, reduce workload, improve efficiency of construction;
3, pipeline normal usage function is ensured.
Accompanying drawing explanation
Fig. 1 is the structural representation of the steel blind plate using state of the embodiment of the present invention;
Fig. 2 is the floor map of the steel blind plate of the embodiment of the present invention;
Fig. 3 is the elevational schematic view of the steel blind plate of the embodiment of the present invention.
In figure: 1 steel blind plate, 2 bolts, 3 outlet valves, 4 gasket seals, 5 steel short tubes, 6 steel flanges sheets, 7PE flange plate, 8 waterstops, 9 bolts hole, 10 apertures.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Embodiment 1
Now refer to Fig. 1 ~ Fig. 3, Fig. 1 is the structural representation of the steel blind plate using state of the embodiment of the present invention, and Fig. 2 is the floor map of the steel blind plate of the embodiment of the present invention, and Fig. 3 is the elevational schematic view of the steel blind plate of the embodiment of the present invention.As shown in the figure, described steel blind plate 1 is a circular steel plate, at the equally spaced bolt hole of its edge placement and waterstop, is provided with a through hole in the middle part of it, is welded with a steel short tube 5 in through hole, and steel short tube two ends are with internal thread; Described steel short tube 5 is inside nominal diameter DN25, and described outlet valve 3 is assemblied on steel short tube 5 one end.
Described steel flanges sheet 6 arranges and treats with bolt 2, steel flanges sheet 6 to be connected the bolt hole that pressure testing PE pipeline flanges matches with described steel blind plate 1, and clamps therebetween by PE pipeline flanges steel flanges sheet 6; Described bolt 2 can select its intensity, quantity and diameter according to the size of the pressure of water supply and sewerage pipeline, to design strength to be 0.8MPa diameter be 500 PE feedwater piping, the common C grade bolt of 24 cover M27 can be selected during pressure testing.
There is provided a rubber sheet gasketing 4, so that liner is at steel blind plate 1 and treat between pressure testing PE pipeline flanges.
The difference maximum compared with PE plug in the past of PE pipeline pressure test blind plate of the present invention is: first uses PE pipeline pressure test blind plate of the present invention, hot-melt adhesive paste is in the past become bolt connect, the working pit of end and intermediate section is reduced a lot, and workload also reduces thereupon; Second party pressure testing complete after the connection of pipeline section and pipeline section, and the leak detection after connecting also facilitates a lot, as there is seepage, overhauls also very convenient; After 3rd pressure testing completes, the blind plate of termination and arm side is not removed, and when blocking cap use, no longer welds PE pipe cap; 4th connection being convenient to subsequent pipeline, the connection that such as successive projects pipeline extends, for connecting the connection of the arm of community, only need shut valve, just can problem reduction with bolt.PE pipeline pressure test blind plate of the present invention can allow operation simplify, and workman is easy to operate, and be convenient to postorder pipeline and connect, and cost is very low, structure is simple, easy to operate, can ensure again the normal usage function of pipeline.
The operating method of PE pipeline pressure test blind plate of the present invention is: be attached to by rubber sheet gasketing 4 on the waterstop of steel blind plate 1, then the bolt hole of the bolt hole of steel blind plate 1 with PE flange plate and steel flanges sheet 6 below thereof is alignd, couple together with bolt 2.Steel short tube 5 is welded on steel blind plate 1, and then on short tube 5 one end processed, outlet valve is installed, bath, exhaust, boosting, test.After PE pipeline pressure test completes, PE pipeline pressure test blind plate of the present invention is not removed when making the blind plate of termination or arm side, when blocking cap use, no longer welds PE pipe cap.
Embodiment 2
When subsequent pipeline connection done by PE pipeline pressure test blind plate of the present invention, shut outlet valve 3 valve, unclamp bolt 2, removal steel blind plate 1, takes away steel flanges sheet 6, adds upper sealing washer with the pipeline with flange plate, just can directly be connected with on-the-spot PE pipeline.
