Abstract

The utility model discloses a fast blocking device for the pipelines, which is provided to overcome the defects of that the big hole of the corroded pipeline cannot be blocked, thus causing serious accident such as the environment pollution, etc. The blocking device comprises two clamp plates which is buckled together to form a catch hoop that can be covered on the outside of the pipeline, and seal pads are arranged between the involution surfaces of the clamp plates and on the intrados on the two ends of the clamp plates, and the inner surface of the clamp plates in the seal gaskets has a concave arc hollow cavity. Because the catch hoop formed by the two clamp plates with an inner hollow cavity which are buckled and fixed together can be covered on the outside of the pipeline, and the periphery is sealed by the seal gaskets, the leakage problem of blocking the large-area leakage point in non-stop production can be solved. The device can be precast to meet the need according to the different diameters of the pipeline. When in use, the device can be connected on spot and has the advantages of convenient transport, fast and convenient installation, in-time blocking, safety and reliability, high working efficiency and reducing the pollution to the greatest extent.

Description

The pipeline rapid plugging device

Technical field

The utility model belongs to maintenance tool, the specifically a kind of leak stopping device that can block the leakage of conveyance fluid medium pipeline fast.

Background technique

The pipeline of conveyance fluid medium owing to corrosion or other reasons, is particularly carried the transfer line of dangerous liquid material, is easy to generate accidents such as irregular explosion or fracture.At present, when pipeline causes local water clock owing to corrosion, to weep point big on the pipeline as pin hole, the method of generally taking is to stop earlier producing pipeline is reduced pressure, film on the partial cover of pipeline weep point then, the son of checking card outside film is fixing, makes film do temporary blocking to leak source.But when the area of leak source is big, just can't solve with above-mentioned way, in case leak generation, also have little time processing and just pollute environment or directly people or thing are worked the mischief, security incident happens occasionally.The way that the solves replacing pipeline that can only stop production completely, the time of delaying is long, influences normally carrying out of work.

The model utility content

Technical problem to be solved in the utility model is, overcoming existing macropore to the corrosion pipeline can't leak stopping, pollutes the shortcoming of major accidents such as environment, and a kind of pipeline rapid plugging device is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the leak stopping device comprises that two can wrap in the clip sheet of pipeline outside collar to lumping together formation, be provided with sealing gasket between the clip sheet involutory surface and on the intrados at clip sheet two ends, be provided with the concave arc shape cavity on interior clip plate inner surface at sealing gasket.

The utility model also has following technical characteristics:

Described by the clip sheet to synthetic clip, link mutually for head and the tail many groups.

Advantage of the present utility model and good effect are that the clip that together forms can wrap in outside the pipeline because two clip sheets of inner band cavity are fastened, and is peripheral with sealing gasket sealing, the leakage problem that can separate the shutoff pipeline large size leakage point that never stops production.Can be according to the bore difference of pipeline, adopt to shift to an earlier date prefabricated mode and satisfies the demand, but field joint during use is carried lightly, it is convenient rapidly to install, and leak stopping is timely, can reduce pollution to greatest extent, safe and reliable, high working efficiency.

Description of drawings

Fig. 1 wraps in the outer schematic perspective view of pipeline for the utility model;

Fig. 2 is that two joint leak stopping devices connect the scheme of installation that wraps in outside the pipeline.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, the leak stopping device comprises clip sheet 1, two 1 pair of clip sheets wrap in leakage point 2.1 outer surfaces of pipeline 2 together, be through fastening composition clips in the hole 1.21 on 1 liang of edge joint dish 1.2 of clip sheet with bolt 7, between the two clip sheets 1 that snap together and the intrados at clip sheet 1 two ends be provided with sealing gasket 3; Be provided with cavity 1.1 at sealing gasket 3 with interior clip sheet 1 internal surface, form the inner chamber that goes in ring like this in the clip, having solved does not stop production gets final product the leakage problem of large size leakage point on the shutoff pipeline.

Among Fig. 2, be provided with spigot 1.3 (referring to Fig. 1) in described relative clip sheet 1 lower end, the adapt clip contact pin 4 head and the tail overlap joint mutually of socket 4.1 of structure is identical, upper end band and described spigot 1.3, two relative then involutory clips that are fixed into, many groups overlap joint type that formation links together, overlap joint mouthful place links with being connected to draw the clasp 6 on 7 is connected fast with hook 5 respectively up and down, can form a new short circuit, can rush to repair fast, what guarantee pipeline does not unimpededly delay production, reduces to greatest extent and pollutes and the generation of other security incidents.

Claims

1, a kind of pipeline rapid plugging device, it is characterized in that: it comprises that two can wrap in the clip sheet of pipeline outside collar to lumping together formation, be provided with sealing gasket between the clip sheet involutory surface and on the intrados at clip sheet two ends, be provided with the concave arc shape cavity on interior clip plate inner surface at sealing gasket.

2, pipeline rapid plugging device as claimed in claim 1 is characterized in that: described by the clip sheet to synthetic clip, link mutually for head and the tail many groups.
