Abstract
The utility model discloses a kind of piping shaft antipriming,Belong to water-tight device field,Including inspection shaft,With the perforate in setting inspection shaft side wall,And the pipeline in perforate,At least provided with a support ring wherein in each perforate,The support ring is fixedly connected with the outer wall of pipeline,Hollow rubber ring is provided with the support ring,Charge valve is provided with the rubber ring,Gap between pipeline and perforate is sealed by hollow rubber ring,And when actually sealing,Gas is filled with rubber ring,Therefore when pipeline radially produces position,Pass through the extruding to rubber ring,So as to change the degree of rubber ring diverse location expansion,Ensure that sealing effectiveness good between pipeline and perforate,Solve piping shaft and enter water problems,The environment created for the maintenance of valve or compensator,Also improve the service life of valve or compensator.
Description
Technical field
A kind of water-tight device is the utility model is related to, especially a kind of piping shaft antipriming.
Background technology
The valve and compensator of heat supply pipeline are equipped with inspection shaft, and pipeline will pass through the inspection shaft borehole wall, widely used at present
Be a kind of method of rubber water-swellable, prevent water from wearing borehole wall tapping by pipeline and being included in well room, but pipeline radial displacement
When larger, the waterstop just loses effect, causes the water outside well to enter by perforate in well room.
Utility model content
Technical assignment of the present utility model is to be directed to above the deficiencies in the prior art, and provides a kind of piping shaft and filled with sealing
Put.
Technical scheme is used by the utility model solves its technical problem：A kind of piping shaft antipriming, including
Inspection shaft, and the perforate in inspection shaft side wall is set, and the pipeline in perforate, wherein in each perforate at least provided with
One support ring, the support ring are fixedly connected with the outer wall of pipeline, hollow rubber ring are provided with the support ring, in institute
State rubber ring and be provided with charge valve, give rubber ring to inflate one by one by charge valve during sealing.
Further improve：In order to ensure there is good sealing effectiveness between pipeline and perforate, therefore the support ring is adopted
It is made of elastomeric material.
Further improve：In order to improve sealing property, two support rings are provided with each perforate, in each support ring
It is equipped with rubber ring.
Further improve：In order to realize the consistent of air pressure in each rubber ring, and the effect of inflation is improved, therefore the rubber
Connected between cushion rubber by gas tube, the charge valve is located on the gas tube.
Further improve：Air gauge is provided with the gas tube.
The advantages of the utility model：Gap between pipeline and perforate is sealed by hollow rubber ring,
And gas is filled with when actually sealing, in rubber ring, and therefore when pipeline radially produces position, by the extruding to rubber ring,
So as to change the degree of rubber ring diverse location expansion, sealing effectiveness good between pipeline and perforate is ensured that, is solved
Piping shaft of having determined enters water problems, for the environment created of maintenance of valve or compensator, also improves making for valve or compensator
Use the life-span.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the partial enlarged drawing at A in the utility model Fig. 1.
Fig. 3 is the schematic diagram connected by gas tube between the utility model rubber ring.
Embodiment
The utility model is described below with reference to Figure of description.
As illustrated, a kind of piping shaft antipriming, including inspection shaft 1, and the perforate 2 in the side wall of inspection shaft 1 is set,
And the pipeline 3 in perforate 2, wherein at least provided with a support ring 4, the support ring 4 and pipeline in each perforate 2
3 outer wall is fixedly connected, and hollow rubber ring 5 is provided with the support ring 4, charge valve 6 is provided with the rubber ring 5,
Inflated one by one to rubber ring 5 by charge valve 6 during sealing；In order to ensure there is good sealing effect between pipeline 3 and perforate 2
Fruit, therefore the support ring 4 is made of elastomeric material；In order to improve sealing property, two supports are provided with each perforate 2
Ring 4, rubber ring 5 is equipped with each support ring 4；In order to realize the consistent of air pressure in each rubber ring 5, and improve inflation
Effect, therefore connected between the rubber ring 5 by gas tube 7, the charge valve 6 is located on the gas tube 7；Filled described
Tracheae 7 is provided with air gauge 8.
Its operation principle is：After pipeline is passed through into perforate, inflated using air pump by charge valve 6 into rubber ring 5, because
It is provided in for rubber ring 5 in support ring 4, movement is produced so as to avoid rubber ring 5 in the axial direction of pipeline 3, it is ensured that
Rubber ring 5 is to the sealing effectiveness of the outer wall of pipeline 3, when pipeline 3 diametrically produces displacement, because rubber ring 5 is hollow knot
Structure, and gas is filled with rubber ring 5, so the outer gap between 3 walls and perforate 2 of pipeline becomes big place, by gas
The effect of expansion ensure that the sealed waterproof effect of rubber ring 5, if being equipped with charge valve 6 on each rubber ring 5, inflate
When need one by one to be inflated rubber ring 5 with air pump, if connected between rubber ring 5 by gas tube 7, then air pump
Complete to inflate all rubber rings 5 simultaneously by the can of gas tube 7, so as to improve operating efficiency, it can also be ensured that each rubber
Air pressure in cushion rubber 5 can be consistent.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
