It connects.
Hanging ring is equipped on the outside of the gland.
The outer diameter of the diversion pipe is 3mm bigger than the internal diameter of air bag to 5mm.
The material of the air bag is natural rubber, silica gel or fluorubber.
The diversion pipe is steel pipe, aluminum pipe, copper pipe or plastic tube.
The diversion pipe of the same internal diameter can be configured with plurality of specifications air bag, and the air bag outer diameter of different size is different.
The utility model has the beneficial effects that: by increasing diversion pipe in air bag, block air bag it is completely enclosed every
Disconnected pipeline, can drain into designated position in time by the liquids and gases that pipeline is left or leaked by diversion pipe, reduce in pipe
Pressure, reduce and block the risk gone out of air bag, in case of emergency can be used as ready-packaged joint use, with bidirectionally conductive
Function, and gland can be dismantled, air bag that can be different according to different selection for pipeline improve the applicability of equipment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- air bag, 2- diversion pipe, 3- flange, 4- gland, 5- gas tube, 6- pressure gauge, 7- air valve, 8- dielectric valve
Door, 9- short tube, 10- hanging ring.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, a kind of multifunctional pipe blocks air bag, including air bag 1, diversion pipe 2, the air bag 1 is annular gas
Capsule, diversion pipe 2 are coaxially mounted in the inner hole of air bag 1, and described 2 one end of diversion pipe is equipped with flange 3, and the other end is equipped with gland 4, institute
It states gland 4 to be sleeved on outside diversion pipe 2, the air bag 1 is equipped with gas tube 5, and gas tube 5 is connected to the inner cavity of air bag 1, and inflates
Pipe 5 is equipped with pressure gauge 6 and air valve 7.
When needing to block pipeline, there are also media in pipeline, and to prevent manifold pressure from increasing, it is difficult to increase installation
Degree opens the medium valve 8 on diversion pipe 2 when installation, then opens air valve 7, and pressure is filled with into air bag 1 by gas tube 5
Contracting air, air bag 1 after inflation by expanding, and when the gas pressure in air bag 1 reaches prescribed requirement, air bag 1 fills up entire pipe
Pipeline is blocked using the frictional force that air bag 1 is generated with inner wall of the pipe, and closes medium valve 8 and air valve 7 by road section, thus
Reach in target pipeline section and water flow is quickly blocked by inflation, convenient for making to pipe first-aid and when speedily carrying out rescue work
Industry, when inflation, 1 inner ring of air bag can be tightly attached to outside diversion pipe 2 under the influence of air pressure, prevent medium in pipeline from diversion pipe 2
It is oozed out in gap between air bag 1, improves the sealing effect for blocking air bag, air gauge can monitor the gas in air bag 1 in real time
Pressure prevents superpressure from air bag 1 being caused to damage, and when the pressure medium in pipeline is excessively high, can open medium valve 8 and carry out pressure release,
The pressure in pipe is reduced, reduces and blocks the risk that air bag is gone out.
Described 2 one end of diversion pipe is equipped with medium valve 8 and short tube 9, and the short tube 9 passes through medium valve 8 and 2 end of diversion pipe
Portion's connection, short tube 9 dock convenient for diversion pipe 2 with other pipelines, improve working efficiency, and medium valve 8 can block gas in installation
Capsule when manifold pressure is excessively high, plays the role of pressure release, reduces and blocks the risk that air bag is gone out, while during operation, as because
When other reasons need to use pipeline internal medium on a small quantity, it can be discharged by medium valve 8, be convenient for constructing.
Adjusting screw thread is equipped on the gland 4 and diversion pipe 2, it is mutual by adjusting screw thread between gland 4 and diversion pipe 2
Connection, by the flange 3 and gland 4 of 2 one end of diversion pipe, air bag 1 can be clamped, and improve the sealing effect for blocking air bag, together
When block different-diameter pipeline when, after gland 4 is unloaded, diversion pipe 2 is pulled out, replaces the air bag 1 of dimension.
Hanging ring 10 is equipped on the outside of the gland 4, convenient for after pipe plugging, air bag 1 is pulled out out of pipeline.
The outer diameter of the diversion pipe 2 is 3mm bigger than the internal diameter of air bag 1 to 5mm, is matched by diversion pipe 2 and the interference of air bag 1
It closes, is tightly attached to air bag 1 on diversion pipe 2, improve the sealing effect for blocking air bag.
The material of the air bag 1 is natural rubber, silica gel or fluorubber, and the high scores such as fabric are added during fabrication
Sub- synthetic material is blocked pipeline, the materials such as silica gel or fluorubber are heat-resist, given birth to so that air bag 1 can expand after inflating
The air bag 1 of production can be used for the closure of high-temperature medium.
The diversion pipe 2 is steel pipe, aluminum pipe, copper pipe or plastic tube, so that diversion pipe 2 is had certain rigidity, fills in air bag 1
It when gas expands, is tightly attached to air bag 1 outside diversion pipe 2, improves the sealing effect for blocking air bag.
The diversion pipe 2 of the same internal diameter can be configured with plurality of specifications air bag 1, and air bag (1) outer diameter of different size is different,
When blocking the pipeline of different-diameter, after gland 4 is unloaded, the air bag 1 of replacement dimension can be replaced, the present apparatus is improved
Use scope.
