Description

Water plugging air bag
Technical Field
The utility model belongs to the technical field of pipeline maintenance, and particularly relates to a water plugging air bag.
Background
In municipal drainage pipeline construction maintenance or replacement process, the sewage that exists in the pipeline often makes unable operation in the construction, in order to make the construction can normal work, often need block rivers, the traditional method is that the brick wall is repaired and blocks rivers, still a commonly used method is that throw away the sand bag and block up water inwards, these two kinds of methods can block up rivers, but the workman is in the pipeline operation that has water under many circumstances, the construction is very inconvenient, dismantle unclean when dismantling, remaining rubbish can also cause secondary pollution to the water, still block up the pipeline when the volume is big.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problems and provides a water plugging air bag.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a water shutoff gasbag, is including supporting a steel section of thick bamboo and the expanded cover of gasbag, the expanded cover of gasbag is established support on the steel section of thick bamboo, the one end an organic whole of supporting a steel section of thick bamboo is equipped with the shutoff pipe, and the other end is equipped with the opening, the diameter of shutoff pipe is less than support the diameter of a steel section of thick bamboo, the mouth of pipe department of shutoff pipe is equipped with the shutoff cap support in the middle of the steel section of thick bamboo seted up along support the radial gas transmission hole of a steel section of thick bamboo, the gas transmission hole is connected the middle part of the expanded cover of gasbag and with the inner chamber intercommunication of the expanded cover of gasbag, the gas transmission hole is connected with the gas-supply pipe.
As a preferred technical scheme, a first gas transmission pipe connector is arranged at the gas transmission hole, a second gas transmission pipe connector is arranged at the end face of the plugging pipe end of the supporting steel cylinder, two ends of the gas transmission pipe are respectively connected with the first gas transmission pipe connector and the second gas transmission pipe connector, the gas transmission pipe is a rigid gas transmission pipe, and the gas transmission pipe comprises a concave U-shaped section.
As a preferable technical scheme, the water shutoff air bag further comprises a traction ring, and the traction ring is fixedly connected to the end face of the shutoff pipe end of the support steel cylinder.
After the technical scheme is adopted, the utility model has the following advantages:
this stifled water gasbag sets up in the pipeline section that needs the shutoff, and to the gas injection of gasbag cover inflation through the gas-supply pipe for the inflation of gasbag cover inflation, the pipeline is sticis to the surface of gasbag cover inflation, makes stifled water gasbag play the shutoff effect to the pipeline. Simultaneously, this stifled water gasbag can also play the effect that reduces pipeline drainage flow, when meetting the too high condition of water pressure, takes off the shutoff cap, because the diameter of shutoff pipe is less than the diameter of pipeline, pipeline discharge through stifled water gasbag reduces greatly, and can not lead to the gasbag to damage because of the too big water pressure that stifled water gasbag received.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples.
As shown in fig. 1-3, the water shutoff air bag comprises a support steel cylinder 1 and an air bag expansion sleeve 2, wherein the air bag expansion sleeve 2 is sleeved on the support steel cylinder 1.
One end of the supporting steel cylinder 1 is integrally provided with a plugging pipe 3, the other end of the supporting steel cylinder is provided with an opening, and the diameter of the plugging pipe 3 is smaller than that of the supporting steel cylinder 1. And a plugging cap 4 is arranged at the pipe orifice of the plugging pipe 3.
The middle of the supporting steel cylinder 1 is provided with a gas transmission hole along the radial direction of the supporting steel cylinder 1, the gas transmission hole is connected to the middle part of the air bag expansion sleeve 2 and communicated with the inner cavity of the air bag expansion sleeve 2, and the gas transmission hole is connected with a gas transmission pipe 5. The air delivery from the middle part of the air bag expanding sleeve 2 is to make the air bag expanding sleeve 2 expand uniformly, if the air delivery from the two sides of the air bag expanding sleeve 2 will cause the air bag expanding sleeve 2 to expand non-uniformly.
The gas transmission hole is provided with a first gas transmission pipe joint 6, the end face of the end of the plugging pipe 3 of the supporting steel cylinder 1 is provided with a second gas transmission pipe joint 7, and two ends of the gas transmission pipe 5 are respectively connected with the first gas transmission pipe joint 6 and the second gas transmission pipe joint 7.
The air delivery pipe 5 is a rigid air delivery pipe, and the air delivery pipe 5 comprises a concave U-shaped section. The purpose that the gas-supply pipe 5 so set up is on the one hand the corner of increase gas-supply pipe, makes the gas transmission smooth and easy, and on the other hand plays the cushioning effect when gassing, avoids the too big gas bag gassing pressure to make gas-supply pipe 5 fracture or throw off.
The water plugging air bag further comprises a traction ring 8, and the traction ring 8 is fixedly connected to the end face of the end of the plugging pipe 3 of the support steel cylinder 1. The traction ring 8 is used for integral traction of the water plugging air bag, so that the water plugging air bag reaches a position to be repaired.
This stifled water gasbag sets up in the pipeline section that needs the shutoff, through gas-supply pipe 5 to the 2 gas injections of gasbag cover that expands for 2 inflation of gasbag cover that expands, the pipeline is sticis to the surface of gasbag cover that expands 2, makes stifled water gasbag play the shutoff effect to the pipeline.
Simultaneously, this stifled water gasbag can also play the effect that reduces pipeline drainage flow, when meetting the too high condition of water pressure, takes off shutoff cap 4, because the diameter of shutoff pipe 3 is less than the diameter of pipeline, pipeline discharge through stifled water gasbag reduces greatly, and can not lead to the gasbag to damage because of the too big gasbag that leads to of water pressure that stifled water gasbag received.
Other embodiments of the present invention than the preferred embodiments described above will be apparent to those skilled in the art from the present invention, and various changes and modifications can be made therein without departing from the spirit of the present invention as defined in the appended claims.
