Description

Continuous blasting and blowing device for pipeline

Technical Field

The utility model belongs to the technical field of pipeline blasting and blowing, and particularly relates to a pipeline continuous blasting and blowing device.

Background

And after the pressure test of the process pipeline and the gas pipeline is qualified, purging the pipeline. Pipeline purging is typically performed using compressed air or steam. In order to save cost and time and ensure safety, compressed air blasting is generally adopted to blast and purge pipelines with larger diameters in particular.

At present, the blasting and purging of the pipeline have the problems that the gas is stopped once every blasting, the blasting sheet is reinstalled, the gas is re-introduced, and the blasting is performed again. The blasting and blowing time is long, the labor cost is high, the compressed air waste is large, and the blowing effect is poor.

Disclosure of utility model

In order to solve the defects in the prior art, the utility model discloses a pipeline continuous blasting purging device which is realized by adopting the following technical scheme.

The utility model provides a pipeline continuous blasting sweeps device, includes the three-way pipe, the both ends of the straight tube of three-way pipe are provided with flange No. one respectively, flange No. one has flange No. two through bolted connection, it is equipped with the rupture disk to press from both sides between flange No. two and the corresponding flange No. one, the intermediate tube of three-way pipe with wait to sweep the pipeline connection, install two motorised valves on the straight tube, two the motorised valve distributes in the intermediate tube both sides.

Further, the third connecting flange at the tail end of the middle pipe is connected with the third connecting flange at the end of the pipeline to be purged through bolts.

Further, the length of the straight pipe of the tee pipe is more than 3 meters.

The utility model has the following beneficial effects:

1. The continuous purging without stopping the gas and the safe replacement of the rupture disk can be realized.

2. The pipe blowing effect is greatly improved.

3. The purge time is greatly shortened.

4. The labor cost is greatly reduced, and the consumption of compressed air is greatly reduced.

FIG. 1 is a schematic diagram of the structure of the present utility model;

In the figure, the reference numerals are three-way pipe 1, straight pipe 2, intermediate pipe 3, first connecting flange 4, bolt 5, bursting disc 6, pipe 7 to be purged, electric valve 8, second connecting flange 9 and third connecting flange 10.

Detailed Description

The present utility model will be further described in detail below with reference to examples, which are provided to illustrate the objects, technical solutions and advantages of the present utility model. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

The numbering of components herein, such as "first," "second," etc., is used merely to distinguish between the described objects and does not have any sequential or technical meaning. The terms "coupled" and "connected," as used herein, are intended to encompass both direct and indirect coupling, unless otherwise indicated. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the device or element in question must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

In the present utility model, unless expressly stated or limited otherwise, a first feature "up" or "down" a second feature may be the first and second features in direct contact, or the first and second features in indirect contact via an intervening medium. Moreover, a first feature being "above," "over" and "on" a second feature may be a first feature being directly above or obliquely above the second feature, or simply indicating that the first feature is level higher than the second feature. The first feature being "under", "below" and "beneath" the second feature may be the first feature being directly under or obliquely below the second feature, or simply indicating that the first feature is less level than the second feature.

As shown in fig. 1, the continuous blasting and purging device for the pipeline comprises a three-way pipe 1, a first connecting flange 4 is respectively arranged at two ends of a straight pipe 2 of the three-way pipe 1, a second connecting flange 9 is connected with the first connecting flange 4 through bolts 5, a rupture disk 6 is clamped between the second connecting flange 9 and the corresponding first connecting flange 4, a middle pipe 3 of the three-way pipe 1 is connected with a pipeline 7 to be purged, two electric valves 8 are arranged on the straight pipe 2, the two electric valves 8 are distributed on two sides of the middle pipe 3, a third connecting flange 10 at the tail end of the middle pipe 3 is connected with a third connecting flange 10 at the end of the pipeline 7 to be purged through bolts 5, and the length of the straight pipe 2 of the three-way pipe 1 is greater than 3 meters.

The working principle of the utility model is as follows:

When the utility model is used for blasting and blowing the pipeline 7 to be blown, the third connecting flange 10 at the end part of the middle pipe 3 is connected with the third connecting flange 10 at the end part of the pipeline 7 to be blown through the bolts 5, then the two side electric valves 8 are alternately opened, when each electric valve 8 is opened, the rupture disc 6 at the corresponding end of the straight pipe 2 is blasted, after one side is blasted, the electric valve 8 is closed, then the other side electric valve 8 is opened, the other side is blasted, and the rupture disc 6 at the last blast hole is simultaneously replaced during the blasting, so that the alternating blasting of the two rupture discs 6 at the two ends of the straight pipe 2 on the three-way pipe 1 is realized, and the cyclic reciprocation is realized until the pipeline blowing meets the design and production requirements, thereby achieving the purposes of continuously blowing without stopping air and safely replacing the rupture disc 6, greatly shortening the blowing effect, greatly reducing the labor cost and greatly reducing the compressed air consumption.
