Abstract
The utility model relates to a sealing pipe plug for a pipeline, which comprises a closing plate and a stopper which is formed by integral connection. The utility model is characterized in that the closing plate is a circular plate; the periphery of the closing plate is integrally provided with a vertical supporting ring; an inner tube type sealing rubber ring is sheathed outside the supporting ring; a rubber ring gasket is arranged between the inner tube type sealing rubber ring and the supporting ring; an air filling and discharging valve is arranged on the inner tube type sealing rubber ring; the stopper is composed of a cross seat and four stop pawls; the cross seat is arranged on one side of the closing plate; the four stop pawls and the cross seat are integrally connected by telescopic casing pipes; fastening bolts for the positioning of stop pawl rods are arranged on the telescopic casing pipes. The utility model has the advantages of convenience manufacture and convenient operation in use.
Description
The utility model belongs to the pipeline special-purpose sealing plug for pipe of check of holding one's breath.
Closed conduit adopted the capsule-type pipe plug when pipeline was held one's breath check in the past.When caliber was very big, the capsule volume of sealing usefulness was bigger.Not only difficulty is manufactured in processing, and execute-in-place is trouble very also, inflation in a large number in capsule, and time-consuming, take a lot of work.
The purpose of this utility model is to propose a kind of sealing plug for pipe technological scheme, and pipe plug processing is manufactured conveniently, uses easy to operate.
Content of the present utility model comprises the stopper that shrouding and one connect, and shrouding is a garden shape plate, and its periphery is integrally formed with vertical filler ring, and the outer sheathed inner tube of a tyre formula O-ring seal of filler ring is provided with the cushion rubber liner between cushion rubber and the filler ring, Air filling and discharging valves is arranged on the cushion rubber; Stopper is located at the Crux of shrouding one side by one and is constituted by four lock pawls that the telescopic tube one connects with Crux, and stop claw bar location clamping bolt is arranged on the sleeve pipe.Combine as a whole by universal rotating shaft between lock pawl and the claw bar.
Characteristics of the present utility model are that the stopper with one is fixed on shrouding in the caliber, and the inflatable inner tube formula O-ring seal that is located at the shrouding periphery with shrouding and ring is realized the sealing to pipeline.Easy and simple to handle, good sealing effect.
Embodiment of the present utility model is as shown in drawings:
Fig. 1 is the plan view of the utility model pipe plug,
Fig. 2 is the side-looking partial cross sectional views of Fig. 1,
Fig. 3 is to use view,
Number in the figure is represented:
1. O-ring seal, 2. cushion rubber liner, 3. shrouding, 4. stopper sheet, 5. Crux, 6. attachment bolt, 7. lock pawl sleeve pipe, 8. lifting bolt, 9. stop claw bar, 10. lock pawl, 11. clamping bolts, 12. manometer tube nozzle assemblies, 13. the suction tude nozzle assembly, 14. O-ring seal valve cocks, 15. charging air inlets, 16. pipeline, 17. air pumps, 18. air valves.
Figure is specified the utility model in conjunction with the embodiments:
Fig. 1, Fig. 2 are the organigrams of the design's pipe plug, are to encircle the inner tube of a tyre formula O-ring seal of establishing 1 by shrouding 3 with on it to constitute seal arrangement.Be fixing cushion rubber 1, between shrouding 3 and cushion rubber 1, establish a liner 2.Stopping device comprises stopper sheet 4, lock pawl sleeve pipe 7, lifting bolt 8, stop claw bar 9, lock pawl 10, clamping bolt 11.Lock pawl 10 is radial support tube 16 inwalls, a screw thread and an axially locating groove is arranged, the figure part omitted on the claw bar 9.Locating slot is in harmony and can be put clamping bolt 11 and go in it.Lifting bolt is regulated claw bar 9 liftings.Sleeve pipe 7 and stopper sheet 4 one.Stopper 4 connects one by bolt 6 and Crux 5, and Crux 5 can be manufactured with shrouding 3 one.Because pipe 16 inside diameter surfaces have irregular radian or fluctuating, concavo-convex place, can the tensioner stop for making lock pawl 10, can be made as ten thousand rotating shafts with the junction of pawl 10 at claw bar 9 and connect, with the angle of adjustment pawl itself and tube wall are closely pasted.
User mode of the present utility model emits air in the O-ring seal 1 of the design's pipe plug as shown in Figure 3, and pipe 16 two ends put into the design's pipe plug then by lock pawl 10 indentation sleeve pipes.Elder generation's tensioner lock pawl 10 makes the pipe plug location.Inflate in cushion rubber through charging air inlet 15, valve cock 14, make cushion rubber tensioner sealed pipe 16 two ends, then the pipe plug installing finishes.Inflate and suppress in the pipe 16 of sealing through air inlet ozzle 13 with air pump 17, checking finishes exits through air valve 18 again.The operation of taking out pipe plug is opposite with the installing operation.
The utility model pipe plug easy accessibility, result of use are good, applicable to water pipe or appendix, compare with traditional aerated capsule, and manufacture is convenient, and it is also convenient to store.
