Abstract
The utility model provides an improved air bag for pipeline seal, which can limit the expansion space of the axle direction of an air bag in a pipeline and strengthen the sealing effect of the radial expansion of the air bag. The basic structure of this improved air bag for pipeline seal is that it includes a pneumatophore with the cylinder arc-shaped top and a gas nipple. The cylindrical surface of the pneumatophore is equipped with a reinforcing band. The utility model is characterized in that the inner of the air bag is equipped with a longitudinal positioning support. The utility model adopts the technical scheme that the inner of the air bag is equipped with a positioning support to limit the axial expansion of the air bag in the pipeline. Under the condition that the air injection amount is increased, the sealing effect of the pipeline is improved by the radial expansion of the air bag, so the utility model is economical and practical, and the operation is easy.
Description
Technical field
The utility model relates to a kind of improved seal for pipe joints air bag, belongs to water supply and sewerage pipeline valve fittings technical field.
Background technique
At present, in the water supply and sewerage pipeline work progress, often need interim enclosure portion pipeline to try the water, the pipeline air bag is the interim instrument of blocking pipe, as 99255132.3 novel pipelines with air bag disclosed technological scheme because this air bag is that rubber material is made mostly, during inflation under the restriction of tube wall, expand along pipeline axial easily, cause airbag aeration inhomogeneous and influence sealing effect.
Summary of the invention
The purpose of this utility model is to provide a kind of improved seal for pipe joints air bag, restriction air bag axial expansion space in pipeline, strengthens the radial expansion sealing effect of air bag.
The technical solution of the utility model is achieved in that this improved seal for pipe joints air bag, and its basic structure comprises that the gentle air sac cylinder of chewing of air sac on cylinder arc top is provided with reinforcing strip, it is characterized in that described air bag inside is provided with longitudinal register and supports.
The inner positioning supports that is provided with of described improved seal for pipe joints air bag is soft chain, supporting bar or supporting band.
The inner upper and lower settings pad of described improved seal for pipe joints air bag is with fixedly connected positioning supports.
The pad of described improved seal for pipe joints air bag inside is double-deck the setting, and pad is bonding with air sac up and down.
The technical solution adopted in the utility model is owing to be provided with positioning supports in air bag inside, make the axial expansion of air bag in pipeline be restricted, under the situation that aeration quantity increases, the air bag radial expansion has improved the effect of blocking pipe, economical and practical, easy operating.
Description of drawings
Fig. 1 is the structural representation of improved seal for pipe joints air bag
Fig. 2 is the schematic representation that another orientation type of the utility model is provided with
Among the figure: 1, air sac 2, gas chew 3,4, pad 5, reinforcing strip 6, nylon support chain 7, supporting bar
Embodiment
Fig. 1, the improved seal for pipe joints air bag of the utility model shown in 2 is chewed 2 and is constituted by air sac 1 is gentle, reinforcing strip 5 is set on the air sac, main innovate point of the present utility model is in air sac 1 inside positioning supports to be set, be used to limit the axial expansion stretching of air bag, for the ease of inflating and carrying, positioning supports generally adopts flexible material to make, as nylon chain 6, rope or supporting bar 7 etc., the Placement of positioning supports and air bag is a upper and lower settings pad 3 in air bag, 4, positioning supports is fixed on the pad, and the instantiation that the utility model provides is that double-deck pad is set, and air sac is bonded between the double-deck pad.This improved seal for pipe joints air bag does not need to change the structure and the inflation mode of existing air bag substantially, and is much better to the plugging effect of pipeline, allows existing pipeline construction personnel accept than being easier to.
Foregoing description only proposes as a kind of enforceable technological scheme of the improved seal for pipe joints air bag of the utility model, not as the single restrictive condition to its structure itself.
