Abstract
The utility model provides a flange connection device, including the connection port that one end agrees with flange port specification mutually and set up the bolt bottom screw seat at the device body other end, connection port's side is provided with the through-hole with the connecting hole fixed connection of flange respectively, be provided with the flange looks fixed connection's of passing through bolt and different specifications fixed orifices on the bolt bottom screw seat. The utility model discloses an accurate connection of different preparation standard flanges provides technical support for conventional maintenance industry implements smoothly to easily new material new equipment is installed and is used on petrochemical's old production line.
Description
Technical Field
The utility model relates to a petrochemical technical field, more specifically relates to a flange joint device.
Background
Petrochemical enterprises often face the problem of flange and valve aging during production and need to replace and maintain. There are multiple preparation standards in old apparatus for producing's pipeline, flange and valve, and specification model on ageing flange and the valve body has been vague, and on-the-spot survey and drawing has measuring error again, if according to measured size determination flange joint size, flange joint is not last when often appearing the construction, causes to rework and brings certain degree of difficulty for conventional maintenance work. In addition, with the continuous development of science and technology, some new materials (such as high-molecular nonmetal pipelines, pipe fittings, flanges and the like) which are developed successfully at present are more suitable for the production devices of petrochemical enterprises, and the production standards of the new materials are single, so that the new materials are difficult to popularize and apply on old production devices. The prior art lacks a connecting device for accurately and effectively connecting flanges with different sizes.
SUMMERY OF THE UTILITY MODEL
Not enough to above-mentioned prior art, the utility model provides a can provide technical support for conventional maintenance industry implements smoothly, the connection problem of different preparation standard flanges when solving conventional maintenance to help the new material flange connecting device who promotes on the old apparatus for producing of petrochemical.
In order to achieve the above object, the utility model provides a following technical scheme realizes:
the utility model provides a flange connecting device comprises the device body, the device body includes the connection port that one end agrees with flange port specification mutually and sets up the bolt bottom screw seat at the device body other end, the side of connection port is provided with the through-hole with the connecting hole fixed connection of flange respectively, be provided with the fixed orifices through bolt and the flange looks fixed connection of different specifications on the bolt bottom screw seat.
The number of the bolt bottom screw seats is consistent with the number of the bolt holes arranged on the flanges with different specifications.
Compared with the prior art, the utility model beneficial effect be: through the through hole of the side of the connecting port, which is fixedly connected with the connecting hole of the flange, and the fixing hole of the bolt bottom screw seat, which is fixedly connected with the flanges of different specifications through the bolt, the accurate connection of the flanges of different manufacturing standards is realized, the technical support is provided for the smooth implementation of the conventional maintenance industry, and the new material and new equipment are easy to install and use on the old production line of the petrochemical industry.

Detailed Description
The present invention will be further explained with reference to the following examples.
A flange connection device as shown in fig. 1, 2 and 3 is constituted by a device body having a flange-like structure with a bidirectional sealing surface, which can be sealingly connected to both an old flange in a production device and a new flange to be connected. The device body comprises a connecting port 5 and a bolt bottom screw seat 4, one end of the connecting port 5 is matched with the specification of a new flange port 7 to be connected, the bolt bottom screw seat is arranged at the other end of the device body, through holes 6 fixedly connected with connecting holes of flanges are respectively formed in the side edges of the connecting port 5, and bolts 8 penetrate through the through holes 6 and the connecting holes of the flanges, so that the flange connecting device is connected with the flanges. The bolt bottom screw seat 4 is provided with fixing holes 2 fixedly connected with flanges 1 of different specifications in the production device through bolts 8, and the bolts 8 penetrate through connecting holes of the flanges 1 of different specifications in the production device and then are inserted into the fixing holes in the bolt bottom screw seat 4, so that the other side of the flange connecting device is fixedly connected with the flanges 1 of different specifications. In the connection process, sealing gaskets 3 are respectively arranged at the contact positions of the two sides of the flange connection device, a new flange port 7 to be connected and flanges 1 with different specifications in the production device.
The number of the bolt base screw seats 4 is consistent with that of the bolt holes arranged on the flanges 1 with different specifications, and the bolt base screw seats 4 are fixed in a positioning welding mode during field installation, so that the accuracy of installation sizes of the flange connecting device and the flanges 1 with different specifications is guaranteed.
The above description is only the preferred embodiment of the present invention, but the present invention is not limited to the above-mentioned specific embodiments, and for those skilled in the art, a plurality of modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all belong to the protection scope of the present invention.
Claims (2)
1. The flange connecting device is characterized by comprising a connecting port and a bolt base screw seat, wherein one end of the connecting port is matched with the specification of the flange port, the bolt base screw seat is arranged at the other end of the device body, through holes fixedly connected with the connecting holes of the flanges are respectively arranged on the side edges of the connecting port, and fixing holes fixedly connected with the flanges of different specifications through bolts are arranged on the bolt base screw seat.
