Description
Technical field
The utility model is that one can repeat charge and discharge airtight bag, belongs to technical field of mechanical equipment.
Background technology
Along with China's rapid economic development, various urban infrastructure gradual perfection, empty stringing is a kind of trend of urban development with entering. Construction hardware standard and cable to underground cable pipeline safeguards that safely operation efficiency it is also proposed higher requirement simultaneously. Conventional underground communication cable, the protective tube of power cable are adopt the materials such as plastics, glass reinforced plastic, cement mostly; and it is embedded in the underground groove dug in advance; and artificial well is set by gauged distance, as construction operation points such as cable distribution, safety inspection, accident repairing, routine maintenances.
Artificial well main body is that fragment of brick adds cement structures and builds into, is connected by burying raceway in advance between each artificial well. If raceway waterproof encapsulation process is improper, time one is long, just there will be the situations such as infiltration, ponding, silt and mouse breeding in raceway, the cable safety in pipeline and ordinary maintenance construction all can be impacted, serious also can cause the accident such as power breakdown or communicating interrupt. Meanwhile, owing to raceway communicates, raceway internal water accumulation flows along physical features, needs the at substantial time to draw water, repairing speed is caused very big obstruction before maintenance. If segmentation can be realized draws water, can greatly improve repairing speed undoubtedly. Therefore for safety precaution and the construction in later period maintenance issues of underground cable pipeline, it is necessary to adopt modern technique and product more to be solved.
Conventional art processing mode: artificial well total solution, this kind of way cost quite height be not suitable for promoting; Two, with cement, leak stopping king, anti-cement etc. material, pipeline is carried out segmented seal leak stopping, but the shortcoming of this way is can because the cracking that expands with heat and contract with cold loses the effect of waterproof between material and pipeline, the sealing material that joining seam maintenance etc. operates destruction cable tube road junction that will be inevitable is done in addition at cable, owing to cable tube road junction is blocked by fixing, often easily pipeline and cable are caused infringement when excavating operation, and later cable dilatation is also inconvenient.
Prior art processing mode: adopt disposable Puffer-type seal for pipe joints bag to carry out segmentation shutoff a kind of at present compares conventional pipe plugging waterproof solution. Adopt disposable Puffer-type seal for pipe joints bag to carry out segmentation shutoff, not only the cable in raceway can be played long-term waterproof, protection against rodents, antitheft effect, cable protection pipe can also be avoided to be destroyed simultaneously. Because what disposable Puffer-type seal for pipe joints bag adopted is flexible blockage technology; as long as just can easily construct by inflating or exit when product installation and removal; not needing to beat excavation with what instrument was required great effort, cable protection pipe would not be caused infringement by nature. But expendable sealing bag can only be inflated once, can not re-use after venting. If carrying out circuit rectification or maintenance, the shutoff again of new product need to be reused. Cost is caused to increase, waste material. Airtight portion uses the easy aging gas leakage of elastomeric material, causes shutoff to lose efficacy.
The shortcoming of prior art: 1, expendable sealing bag can only be inflated once, can not re-use after venting. If carrying out circuit rectification or maintenance, product innovation shutoff again need to be reused. Cost is caused to increase, waste material. 2, airtight portion uses the easy aging gas leakage of elastomeric material, causes shutoff to lose efficacy. 3, charge operation difficulty is big, it is necessary to carrying out tubule with specialty instrument and connect, strongly professional, efficiency is low. 4, after having inflated, difficulty extracted by tubule, it is easy to disconnected pipe gas leakage occur, length consuming time inflated by tubule.
Practical novel content
For the deficiency that prior art exists, the utility model object is to provide one can repeat charge and discharge airtight bag, and to solve in above-mentioned background technology the problem proposed, the utility model is easy to use, convenient operation, good stability, reliability height.
In order to realize above-mentioned purpose, the utility model realizes by the following technical solutions: one can repeat charge and discharge airtight bag, comprise airbag and inflation mouth, it is characterized in that: described inflation mouth is arranged on airbag surface, described inflation mouth is by TPR adhesive seal mechanism, stainless steel packing ring, silicone gasket, through hole screw and nut, gas lid is formed, described TPR adhesive seal mechanism is arranged on airbag inside, described TPR adhesive seal mechanism is arranged on the lower section bottom through hole screw, described TPR adhesive seal mechanism is connected with bottom through hole screw, through hole screw it is connected with below described nut.
Further, described airbag surface is provided with stainless steel packing ring and silicone gasket with the junction of through hole screw.
Further, described silicone gasket is provided with two, and one of them is arranged on bottom through hole screw and in airbag between face, one of them is arranged between stainless steel packing ring and airbag surface.
Further, it is inserted with Aerating needle above described through hole screw.
Further, it is stamped gas lid above described through hole screw.
The beneficial effects of the utility model: one of the present utility model can repeat charge and discharge airtight bag, employing can repeat charge and discharge airtight bag and carry out shutoff, can repeat charge and discharge gas and use. Save material and change cost, solve the problem that prior art can only inflate single use. Cancel the connection of inflation tubule, directly use the inflation of universal Aerating needle. Make charge operation simpler, it is not necessary to expertise gets final product complete operation, and Aerating needle buying face is extensively cheap, saves construction cost. Solve the problem that prior art needs could inflate with tubule connection product, save material cost.Resistance to air loss is good, it is to increase high/low temperature tolerance, the protection against corrosion time limit, and longer work-ing life, saves use cost. Solve the problem that prior art uses the easy aging gas leakage of rubber components. Inflation is installed simpler, convenient, save material cost, save the engineering time, it is to increase efficiency. Solving prior art installs complicated, the problem that charge operation is strongly professional, difficulty is high.
