Problems solved by technology

Its advantage is that the cost of plugging is low, but because it is a temporary plug, its main disadvantage is that the blind plate will cause considerable damage to the nozzle during the welding and cutting process, and the recycling rate of the blind plate is low
On the other hand, blind plates are easily stolen by locals to sell scrap iron

Abstract

The invention discloses an umbrella support type temporary pipeline plugging device. A driving bolt (2) of a fixedly connected hand wheel (1) is connected with a central shaft strut (11), the other end of the central shaft strut (11) is connected with eight supports (10) connected with brackets (9), two adjacent brackets (9) are connected with a left embedded leather cup supporting sheet (8), andthe left embedded leather cup supporting sheet (8) in a ring shape is propped against a left polyurethane leather cup (7); the central shaft strut (11) passes through the central holes of the left polyurethane leather cup (7) clamped by a left cup external fixing plate (5) and a left cup internal fixing plate (6) and a right polyurethane leather cup (12) clamped by a right cup external fixing plate (3) and a right cup internal fixing plate (4) on two sides of the cup bottom; and the right side of the left cup external fixing plate (5) is connected the eight supports (10) connected with the brackets (9), the two adjacent brackets (9) are connected with a right embedded leather cup supporting sheet (13), and the right embedded leather cup supporting sheet (13) in a ring shape is propped against a right polyurethane leather cup (12).

Description

technical field [0001] The invention relates to an umbrella support type pipeline temporary sealing device for temporarily sealing pipelines, especially long-distance pipelines, and relates to the technical field of pipeline systems. Background technique [0002] During the construction of long-distance pipelines, there are two main stages that require temporary sealing of pipelines. The first stage is that there is a period of vacancy for a period of time when the pipeline is welded on the ditch and waiting for the next ditch to be filled; the second stage is that there is a period of vacancy when the pipeline is waiting for the connection after drying. In the first stage, because the pipeline is placed in the open environment, if the temporary blockage is not carried out, the inner wall of some pipelines that have not undergone anti-corrosion process will be severely corroded due to various natural environmental factors, and a certain degree of natural pollution will be ca...
