Abstract
The utility model relates to the technical field of pipe plugging, and provides a pipeline plugging device. The pipeline plugging device comprises a ball body and a pressure-relief pipe. A pressure-relief hole is formed in the ball body, the inner end of the pressure-relief pipe is fixed in the pressure-relief hole, and a valve is fixedly mounted on the pressure-relief pipe. The pipeline plugging device is simple in structure and convenient to use; and through matching of the pressure-relief pipe and the pressure-relief hole which are arranged in the ball body, media inside a pipeline can be rapidly discharged, and thus potential safety hazards are reduced.
Description
Technical field
The utility model relates to the pipe plugging technical field, is a kind of pipe plugging device.
Background technique
Existing pipeline plug generally adopts ball sealer; In use, can directly pipeline internal medium be enclosed in the pipeline,, bring very big danger for pipeline maintenance or replacing because the pipeline internal medium build pressure raises gradually; Especially the harmfulness brought of combustion gas or other flammable explosive medium is bigger.
Summary of the invention
The utility model provides a kind of pipe plugging device, has overcome the deficiency of above-mentioned prior art, and it can solve there is potential safety hazard in existing pipeline plug when the flammable explosive medium of shutoff combustion gas or other problem.
The technical solution of the utility model is achieved like this: a kind of pipe plugging device, comprise spheroid and relief tube, and relief hole is arranged in spheroid, the inner of relief tube is fixed in the relief hole, is installed with valve on relief tube.
The outside with upper sphere is fixed with rubber body.
The outer end of above relief tube is installed with rapid pipe joint.
The inner of above relief tube is fixed in the relief hole by screw thread.
The utility model is simple in structure, and is easy to use; By the cooperation of relief hole and relief tube is set in spheroid, can fast pipeline internal medium be emitted, therefore reduced potential safety hazard.
Description of drawings
Fig. 1 looks the broken section structural drawing for master of the present utility model.
Coding among the figure is respectively: 1 is spheroid, and 2 is relief tube, and 3 is valve, and 4 is rubber body, and 5 are rapid pipe joint.
Embodiment
As shown in Figure 1, this pipe plugging device comprises spheroid 1 and relief tube 2, in spheroid 1 relief hole is arranged, and the inner of relief tube 2 is fixed in the relief hole, is installed with valve 3 on relief tube 2.During use, pipeline internal medium can be emitted, therefore reduce potential safety hazard by relief tube 2.
As shown in Figure 1, the outside of spheroid 1 is fixed with rubber body 4, is convenient to like this and seal for pipe joints.
As shown in Figure 1, the outer end of relief tube 2 is installed with rapid pipe joint 5, is convenient to like this be connected with other pipe fittings.
As required, the inner of relief tube 2 is fixed in the relief hole by screw thread; Perhaps the inner of relief tube 2 is fixed by welding in the relief hole.
