Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It is to be understood that the pipe aligning device for discharging residual water in a pipe described herein is a preferred embodiment, and is only used for illustrating and explaining the present invention, and does not constitute a limitation of the present invention.
Embodiment is used for discharging the residual water flow's in the pipeline interfacing apparatus
In this embodiment, as shown in fig. 1, a pipe butting device for discharging residual water flow in a pipe comprises an original pipe 1 through which water flow passes and a pipe 2 to be welded for extending the original pipe 1. The original pipeline 1 is a pipeline which is put into use and has water circulation, and a valve is arranged on a main pipe of the original pipeline 1 and used for controlling the on-off of water flow. The pipeline 2 to be welded is a pipeline needing to be welded in the maintenance or reconstruction process, the pipeline 2 to be welded is connected to the original pipeline 1 to form a new branch pipeline, or the original pipeline 1 is cut off, and a new pipeline is welded to complete reconstruction work.
The workman is at the during operation, need close the valve, cuts off rivers, because the ageing of valve, can have the phenomenon of leaking unavoidably, rivers to the welding mouth after, seriously influence welded quality, consequently, this embodiment has set firmly drainage device 3 in former 1 bottoms of pipeline, outside the former pipeline 1 of drainage device 3 discharge of messenger's outer water, guarantee the drying of welding mouth. The drainage device 3 of this embodiment adopts the common pipe of stainless steel in construction site, welds the pipe to former pipeline 1 on, then stretches into the pipe with the opening device among the prior art, offers the drainage mouth 4 that is arranged in leading water to the pipe on former pipeline 1. The pipe is welded earlier to this embodiment, then at former 1 upper shed of pipeline, can guarantee to flow from drainage mouth 4 and come water and all flow out through the pipe.
The detachable one end that former pipeline 1 was not connected to drainage device 3 is equipped with sealing member 5, be equipped with on the sealing member 5 with drainage device 3's outer wall matched with recess, and the sealed one end of recess forms the sealed end of sealing member 5, and the recess is the cylinder promptly, and one end is sealed. The groove inner wall of the sealing element 5 is sleeved on the outer wall of the round pipe, one end of the round pipe, which is not connected with the original pipeline 1, is in contact with the bottom of the groove, a sealing rubber mat 6 is arranged between the bottom of the groove and the end face of the round pipe, the area of the sealing rubber mat 6 is larger than the cross-sectional area of the round pipe, and the sealing element 5 can play a role in sealing when being tightly connected with the round pipe.
Be equipped with the external screw thread on the outer wall of pipe, be equipped with on the inner wall of the recess of sealing member 5 with external screw thread complex internal thread, be about to the internal thread on the recess inner wall and the external screw thread complex on the pipe, make sealing member 5 cup joint on the pipe. After the welding is finished, when normal water passing is needed in the pipeline, one end of the circular pipe, which is not connected with the original pipeline 1, is in close contact with the bottom of the groove through the sealing rubber gasket 6, the sealing piece 5 is rotated and is tightly connected with the circular pipe, and the drainage device 3 cannot leak water.
When using this embodiment, need cut former pipeline 1 and weld new pipeline again, perhaps need connect the tributary pipeline on former pipeline 1, close the valve earlier, cut off flowing water, then weld the pipe in the bottom of former pipeline 1, punch on former pipeline 1 through the pipe, form drainage mouth 4, make the outer water that leaks of valve pass through drainage mouth 4 flow direction pipes, discharge at last. The drainage in-process will be treated welded pipe 2 and former pipeline 1 and weld, and the welding is accomplished the back, fixes sealing member 5 on the pipe, makes the opening part of pipe sealed, prevents the water outflow, and for the sealed effect of reinforcing, this embodiment adopts the welded mode, with sealing member 5's circumference gap and pipe welding together, even the pressure of the former interior rivers of increase, also can not take place outer hourglass phenomenon.
