Description

Corrosion-resistant pipeline connecting flange

Technical Field

The utility model relates to a flange equipment technical field specifically is a corrosion-resistant pipeline flange.

Background

The flange is the important jointing equipment among current all kinds of pipe connection, and in use discovers that current flange mainly realizes connecting two ring flanges through a plurality of bolts to establish at least one deck seal gasket between two ring flanges, then realize sealing to connecting the operation face through the seal gasket. Therefore, in the work, often make the inboard direct contact of gasket convey the material, and many liquid all have corrosiveness, under long-time work, can damage the gasket, reduce the life of gasket, the difficult location of installation of gasket simultaneously often can follow the ring flange landing, and then increase the installation time of gasket. In addition, in the process of conveying corrosive materials, in order to improve the corrosion resistance of the flange, an inner cavity of the existing flange is provided with an anticorrosive coating, so that although the corrosion resistance of the flange is improved to a certain extent, the flange plate can only be replaced by a new flange plate after the protective structure is damaged, the integral scrapping of the original flange is caused, and the use cost is increased. In view of this, we propose a corrosion resistant pipe coupling flange.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution:

the first embodiment is as follows: the utility model provides a corrosion-resistant pipeline flange, including left flange 1, 1 one end of left flange has right flange 2 through 3 cooperation fixation nut 4 demountable installation of fixing bolt, 1 one end of left flange is provided with gasket placement mechanism 6, 1 inner chamber of left flange and 2 inner chamber threaded connection of right flange have protection machanism 5, protection machanism 5 includes first protective tube 51, second protective tube 52, locating piece 53, constant head tank 54, first protective tube 51 one end joint has second protective tube 52, second protective tube 52 one end is provided with constant head tank 54, constant head tank 54 inner chamber sliding connection has locating piece 53, locating piece 53 one end and first protective tube 51 fixed connection, first protective tube 51 surface and 1 threaded connection of left flange, second protective tube 52 surface and 2 threaded connection of right flange. Because second protective tube 52 one end is provided with constant head tank 54, when passing through the ring flange connecting tube, then need place constant head tank 53 and accomplish the location to left flange 1 and right flange 2 to constant head tank 54, then be connected together left flange 1 and right flange 2 through fixing bolt 3 cooperation fixing nut 4, when the inside corruption of ring flange is impaired back, arrange the inside corrosive materials of pipeline at first, demolish fixing bolt 3 after that, reuse instrument cooperation constant head tank 53 and constant head tank 54 take out first protective tube 51 and second protective tube 52 from left flange 1 and right flange 2 inner chamber respectively, install in left flange 1 and right flange 2 respectively with new first protective tube 51 and second protective tube 52 after that, and then accomplished the change to ring flange protection mechanism 5 only, and need not change the ring flange whole, use cost has been practiced thrift.

The second embodiment is different from the first embodiment in that the gasket placing mechanism 6 includes a partition board 61, a placing groove 62, a telescopic cavity 63, a blocking rod 64, a telescopic spring 65 and a first clamping groove 66, the placing groove 62 is arranged between the partition board 61 and the partition board 61, the gasket 7 is arranged on one side of an inner cavity of the placing groove 62, the telescopic cavity 63 is arranged on one side of the inner cavity of the placing groove 62, the blocking rod 64 is slidably connected to one side of the inner cavity of the telescopic cavity 63, the telescopic spring 65 is fixedly connected to the middle portion of the outer surface of the blocking rod 64 through a protrusion, one end of the telescopic spring 65 is fixedly connected to the telescopic cavity 63, one end of the blocking rod 64 is arc-shaped, one end of the left flange 1 is fixedly connected to the partition board 61, and one end of the right flange 2 is provided with the clamping groove 66 for the partition board 61 to be inserted. Because 1 one end fixedly connected with baffle 61 of left flange, when preparing installation gasket 7, place gasket 7 on standing groove 62 earlier, press down gasket 7 again, make 7 one side extrusion shelves pole 64 of gasket, drive shelves pole 64 and to the removal of flexible chamber 63 position, thereby make gasket 7 cross shelves pole 64, then under expanding spring 65's effect, it resets to drive shelves pole 64, thereby it is spacing in standing groove 62 inner chamber to make shelves pole 64 with gasket 7, avoid the gasket to drop from the ring flange when installing fixing bolt 3, install fixing bolt 3 and fixation nut 4 after that, make baffle 61 enter into draw-in groove 66, make the conveying material can not contact gasket 7, increase gasket 7's life.

When the pipeline is connected through the flange plate, the gasket 7 is firstly placed on the placing groove 62, then the gasket 7 is pressed downwards, one side of the gasket 7 extrudes the blocking rod 64, the blocking rod 64 is driven to move towards the position of the telescopic cavity 63, so that the gasket 7 crosses the blocking rod 64, then the blocking rod 64 is driven to reset under the action of the telescopic spring 65, so that the blocking rod 64 limits the gasket 7 in the inner cavity of the placing groove 62, the gasket is prevented from falling off from the flange plate when the fixing bolt 3 is installed, then the fixing bolt 3 and the fixing nut 4 are installed, the partition plate 61 enters the clamping groove 66, so that the conveyed material cannot contact the gasket 7, the service life of the gasket 7 is prolonged, then the positioning block 53 is placed on the positioning groove 54 to complete the positioning of the left flange 1 and the right flange 2, and simultaneously the left flange 1 and the right flange 2 are connected together through the fixing bolt 3 in cooperation with the fixing nut 4, after the inside corruption of ring flange is impaired, arrange the inside corrosive materials of pipeline to the greatest extent earlier, demolish fixing bolt 3 after that, reuse instrument cooperation locating piece 53 and constant head tank 54 take out first protective pipe 51 and second protective pipe 52 from left flange 1 and right flange 2 inner chamber respectively, install left flange 1 and right flange 2 respectively with new first protective pipe 51 and second protective pipe 52 after that, and then accomplished the change to ring flange protection mechanism 5 only, and need not change the ring flange whole, use cost has been practiced thrift.
