Problems solved by technology

However, due to some reasons, the pipeline valves often cannot be closed. At this time, it is usually necessary to expand the isolated production area, and sometimes the entire production system will be shut down, which will cause huge economic losses to the enterprise.

Embodiment Construction

[0032] The following will further explain the connector leakage prevention device of the present invention in conjunction with the description of the drawings and specific implementation methods, but the explanation does not constitute an improper limitation of the technical solution of the present invention.

[0033] Fig. 1 shows the structure of the anti-leakage device for connectors in an embodiment of the present invention.

[0034]As shown in Figure 1, in this embodiment, a connector leakage prevention device includes a connector 11 and a leak-proof casing 12, the connector 11 is used to fixedly connect two adjacent pipelines, and the leakage-proof casing 12 is hermetically sealed. It is arranged outside the connecting piece 11 to form a closed chamber a between the leakage-proof casing 12 and the connecting piece 11, wherein the leakage-proof casing 12 includes a hard bracket 13 and a soft shell part 14, and the hard bracket 13 is hermetically sealed Fixedly connected to...

Abstract

The invention discloses a leakproof device of a connecting part. The leakproof device comprises the connecting part and further comprises a leakproof shell arranged on the periphery of the connecting part in a seal manner, a closed cavity is arranged between the leakproof shell and the connecting part, and the leakproof shell at least comprises a soft shell portion; when the connecting part leaks, the soft shell portion shows visually-checked shape changes. According to the leakproof device of the connecting part, a pipeline for conveying gas can be effectively prevented from leaking towards the exterior, production process safety is improved, and production and running stability is ensured. In addition, through observing of the appearance shape of the leakproof device of the connecting part, whether medium leakage happens to the device or not can be rapidly, conveniently and rapidly judged, a certain specific gas leakage point can be determined, and the judgment process saves time and labor. In addition, the leakproof device of the connection part is simple in structure and suitable for modification of various gas conveying pipelines in a production line.

Description

technical field [0001] The invention relates to a protection device, in particular to a protection device for a connecting piece. Background technique [0002] Metal bellows expansion joints and mating flanges are common connections on pipelines, and have been widely used in various industrial manufacturing and housing design fields such as electric power, petrochemical, heating, steel, and urban construction. However, leakage accidents of metal bellows expansion joints and matching flanges frequently occur due to various reasons such as material aging, external interference, transmission medium replacement, and equipment damage. Public safety incidents occur, therefore, it is necessary to conduct timely detection and evaluation of its use status and service life. [0003] At present, the detection and evaluation of metal bellows expansion joints is mainly after the leakage, and the lagging detection and evaluation methods cannot timely and effectively warn and avoid the fr...
