Description

Device for flushing and emptying pressure pipeline

Technical Field

The utility model relates to a pipeline under pressure technical field specifically relates to a device that is used for pipeline under pressure to wash and unloading.

Background

After the pressure pipeline construction is completed, the pipeline is required to be washed, and when the pressure pipeline is overhauled and maintained, water in the pipeline is required to be emptied. The pressure pipeline generally requires a mud discharge valve and a mud discharge wet well to be arranged at a low point, and the method generally refers to the mud discharge valve and the mud discharge wet well in 'outdoor water supply pipeline auxiliary structure' 07MS 101-2. After the pipeline is laid and the hydrostatic test is finished, the pipeline needs to be flushed, the pipeline can only be flushed through a mud valve and a mud draining wet well at the moment, and after the pipeline normally runs, if the pipeline is damaged and needs to be maintained, water in the pipeline also needs to be emptied. Because pipeline pressure is often higher, flow, pressure are all great when the pipeline washes, and the mud valve bore of implementing according to the atlas is all generally smaller, and the flow capacity is limited, and pipeline washes time very long, and when pipeline pressure was high, the mud valve can not be opened totally, and the aperture is restricted, otherwise the wet well water is difficult to in time overflow and spill out ground, consequently, traditional mud wet well is difficult to satisfy the pipeline and washes the requirement.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a device for pipeline under pressure washes and unloading solves the problem that pipeline under pressure washed and unloaded.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a device for pipeline under pressure washes and unloading, wash the person in charge that unloading device set up including the level, its characterized in that, the one side of being responsible for is equipped with and is responsible for the first branch pipe that perpendicular intercommunication and level set up, be equipped with the valve on the first branch pipe, the one end that is responsible for was kept away from to first branch pipe is equipped with the second branch pipe that communicates and vertical setting perpendicularly with first branch pipe, top one side of second branch pipe is equipped with the drain pipe that sets up with perpendicular intercommunication of second branch pipe and level.

Preferably, a valve well is arranged at the valve.

Further preferably, a water collecting pit is arranged at the bottom of the second branch pipe, and a blind plate is arranged at the top of the second branch pipe.

Still further preferably, the tail end of the drain pipe is provided with a drainage channel.

Compared with the prior art, the beneficial effects of the utility model are that:

the pipeline with large diameter is adopted, so that the pipeline is convenient to flush; the vertical branch pipe is adopted to replace a wet well, so that the water in the pipe is prevented from overflowing out of the ground when the water pressure in the pipe is high; the vertical branch pipe is provided with a blind plate, so that the pipeline can be emptied conveniently.

Drawings

FIG. 1 is a schematic front view of the flushing and emptying device of the present invention;

FIG. 2 is a schematic top view of the flushing and emptying device of the present invention

In the figure: the system comprises a main pipe 1, a first branch pipe 2, a valve 2.1, a valve well 2.2, a second branch pipe 3, a sump 3.1, a blind plate 3.2, a drain pipe 4 and a drainage channel 5.

Detailed Description

As shown in fig. 1 and 2, the utility model relates to a device for pressure pipeline washing and emptying, the washing and emptying device comprises a main pipe 1 which is horizontally arranged, one side of the main pipe 1 is provided with a first branch pipe 2 which is vertically communicated with the main pipe 1 and is horizontally arranged, the first branch pipe 2 is provided with a valve 2.1, one end of the first branch pipe 2, which is far away from the main pipe, is provided with a second branch pipe 3 which is vertically communicated with the first branch pipe 2 and is vertically arranged, and one side of the top of the second branch pipe 3 is provided with a drain pipe 4 which is vertically communicated with the second branch pipe 3 and is horizontally arranged; a valve well 2.2 is arranged at the position of the valve 2.1; a water collecting pit 3.1 is arranged at the bottom of the second branch pipe 3, and a blind plate 3.2 is arranged at the top of the second branch pipe 3; the tail end of the drain pipe 4 is provided with a drainage channel 5, and all the pipelines are large-diameter pipelines with the pipe diameters not larger than that of the main pipe 1.

The utility model discloses a realize like this: when the pipeline is washed, the valve 2.1 is opened, and water in the main pipe 1 sequentially passes through the first branch pipe 2, the second branch pipe 3 and the water discharge pipe 4 to enter the drainage channel 5 under the action of pressure.

When the pipeline needs to be emptied, the valve 2.1 and the blind plate 3.2 on the second branch pipe 3 are opened, the submersible pump is put into the water collecting pit 3.1 from the top of the second branch pipe 3, and the water collecting pit 3.1 is located at the lowest position of the whole device, and the water in each pipe can directly or indirectly reach the water collecting pit 3.1, so that the water in the pipe can be pumped and drained completely through the water pump.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
