Abstract
The utility model relates to one and can to discharge water the airtight water blocking of drainage pipeline, relate to technical field of pipeline construction, comprise bladders, flexible pipe, valve, outlet pipe, described bladders inside is hollow, described flexible pipe passes to the other end from bladders one end through bladders inside, described flexible pipe and described bladders joint sealer seal, and described bladders is provided with the inflation inlet with one-way valve, described valve connecting hose and outlet pipe.The beneficial effects of the utility model: by discharging water from the hose connection valve door that passes of bladders inside, had not only been beneficial to the speed of discharging water but also had accomplished to discharge water controlled, there will not be the phenomenon that pipeline opening has water to overflow.
Description
Technical field
The utility model relates to technical field of pipeline construction, is specifically related to one and can discharges water the airtight water blocking of drainage pipeline.
Background technique
After gravity pipe line has been constructed, according to municipal construction regulatory requirements, pipeline closed-water test must be done before backfill, be used for checking pipeline water percolating capacity.Need during test to carry out shutoff piecemeal to pipeline, the method used at present loads to close water ballonet in pipeline, carries out inflation and make it to expand, until close water ballonet to fill up whole conduit section, reach the plugging effect of pipeline to air bag.Exit to air bag after closed-water test completes, water is flowed out from the gap of air bag and tube wall, this method slow and water of speed that discharges water is easy to overflow from pipeline opening.
Model utility content
The purpose of this utility model is to provide one and can discharges water the airtight water blocking of drainage pipeline, is discharged water, accomplish the controllability discharged water by valve.
To achieve these goals, the technological scheme that the utility model adopts is:
One can discharge water the airtight water blocking of drainage pipeline, comprise bladders, flexible pipe, valve, outlet pipe, described bladders inside is hollow, described flexible pipe passes to the other end from bladders one end through bladders inside, described flexible pipe and described bladders joint sealer seal, described bladders is provided with the inflation inlet with one-way valve, described valve connecting hose and outlet pipe.
As optimal way, described bladders is cydariform, tubular or spherical.
As optimal way, described bladders external diameter is 49mm ~ 1450mm.
The beneficial effects of the utility model: by discharging water from the hose connection valve door that passes of bladders inside, had not only been beneficial to the speed of discharging water but also had accomplished to discharge water controlled, there will not be the phenomenon that pipeline opening has water to overflow.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural drawing of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, one can discharge water the airtight water blocking of drainage pipeline, comprise bladders 1, flexible pipe 2, valve 3, outlet pipe 4, described bladders 1 inside is hollow, described flexible pipe 2 passes to the other end from bladders 1 one end through bladders 1 inside, described flexible pipe 2 seals with sealer with described bladders 1 joint 21, and described bladders 1 is provided with the inflation inlet 11 with one-way valve, described valve 3 connecting hose 2 and outlet pipe 4.
When carrying out closed-water test, the airtight water blocking of drainage pipeline that can discharge water puts into pipeline, is inflated by inflation inlet 11, and bladders 1 expands until fill up whole conduit section, reaches the shutoff of pipeline, and closed-water test is carried out in water filling; After closed-water test terminates, open valve 3, water flow to outlet pipe 4 by the flexible pipe 2 of bladders 1 inside, is discharged or water is discharged into given place by connecting water pipe by outlet pipe 4.
Bladders 1 is cydariform, tubular or spherical, and bladders external diameter is 49mm ~ 1450mm, can adapt to the pipeline that caliber is 50mm ~ 1500mm.By discharging water from the hose connection valve door that passes of bladders inside, being not only beneficial to the speed of discharging water but also having accomplished to discharge water controlled.Do not need to exit to the bladders 1 of the airtight water blocking of drainage pipeline that can discharge water, can continue as plugging action, for the closed-water test work of next section.
More than show and describe basic principle of the present utility model and major character; the technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
1. the airtight water blocking of drainage pipeline that can discharge water, comprise bladders, flexible pipe, valve, outlet pipe, it is characterized in that: described bladders inside is for hollow, described flexible pipe passes to the other end from bladders one end through bladders inside, described flexible pipe and described bladders joint sealer seal, described bladders is provided with the inflation inlet with one-way valve, described valve connecting hose and outlet pipe.
2. one according to claim 1 can discharge water the airtight water blocking of drainage pipeline, it is characterized in that: described bladders is cydariform, tubular or spherical.
