Description
Technical Field
The utility model relates to a connecting piece technical field specifically indicates a flange connecting piece.
Background
Flange connectors, also known as flanges and flanges, are parts that interconnect pipelines and valves. The flange generally comprises a flange body, wherein connecting holes for connection are formed in the flange body, the existing flange is simple in structure and has the advantages of convenience for batch production and wide application range, but the existing connecting flange is relatively single in function, connection tightness cannot be guaranteed in occasions with high requirements, and the use requirements cannot be met; simultaneously some flange joint spare increase spread groove and connecting strip on different flange bodies for the compactness of strengthening the connection, this makes flange joint spare need supporting the use, need find specific subassembly when changing, and it is inconvenient to use.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is defect in above-mentioned traditional flange joint spare structure and function, provide a connect that compactness is good, convenient to use, be convenient for maintain the flange joint spare of changing.
In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a flange connecting piece, includes the flange body, flange body center department is equipped with the intercommunicating pore, the intercommunicating pore outside evenly is equipped with the connecting hole on the flange body, the interval is equipped with spread groove and connecting block between the positive connecting hole of flange body, be equipped with the screw hole on the connecting block, screw hole extending direction is unanimous with the connecting block extending direction, the flange body outside is equipped with rather than threaded connection's fastening bolt, fastening bolt extends to in the spread groove to unanimous with the spread groove extending direction, flange body back intercommunicating pore outside connecting pipe.
Compared with the prior art, the utility model the advantage lie in: this flange joint spare, the interval is equipped with spread groove and connecting block on the flange body openly, be equipped with the screw hole on the connecting block, threaded connection has the fastening bolt who extends to in the spread groove on the flange body, when the pipeline is connected through flange joint spare, stagger certain angle with two flange joint spares, make a flange joint spare's connecting block be connected with another flange joint spare's spread groove, the fastening bolt of screwing, pass the connecting hole with the bolt again, and fixed by the nut, make this flange joint spare's connection compactness good, flange joint spare need not specific supporting use simultaneously, convenient change.
As a modification, the connecting groove is the same size as the connecting block.
As a modification, the length of the threaded hole is more than half of the length of the connecting block.
As an improvement, the inner surface of the connecting pipe is provided with an internal thread, and the outer surface of the connecting pipe is provided with an external thread.
As a modification, the length of the fastening bolt is equal to the sum of the length of the threaded hole and the distance from the side surface of the flange body to the connecting groove.
As a modification, the number of the connecting holes is at least six.
Drawings
Fig. 1 is a front view of a flange connector according to the present invention.
Fig. 2 is a right side view of the flange connector of the present invention.
As shown in the figure: 1. the flange body, 2, intercommunicating pore, 3, connecting hole, 4, connecting groove, 5, connecting block, 6, screw hole, 7, fastening bolt, 8, connecting pipe.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Combine the figure, a flange joint spare, including flange body 1, 1 center department of flange body is equipped with intercommunicating pore 2, 2 outsides evenly are equipped with connecting hole 3 on the flange body 1, the interval is equipped with spread groove 4 and connecting block 5 between 1 front connecting hole 3 of flange body, be equipped with screw hole 6 on the connecting block 5, 6 extending direction of screw hole are unanimous with 5 extending direction of connecting block, the 1 outside of flange body is equipped with fastening bolt 7 rather than threaded connection, fastening bolt 7 extends to in the spread groove 4 to it is unanimous with 4 extending direction of spread groove, 2 outside connecting pipes 8 of the back intercommunicating pore of flange body 1.
The coupling groove 4 is the same size as the coupling block 5 so that the coupling groove 4 can be tightly coupled with the coupling block 5.
The length of the threaded hole 6 is larger than half of the length of the connecting block 5, and the connecting tightness is guaranteed.
The internal surface of the connecting pipe 8 is provided with internal threads, and the external surface of the connecting pipe 8 is provided with external threads, so that the connecting pipe 8 can be connected with pipelines with different pipe diameters.
The length of the fastening bolt 7 is equal to the sum of the length of the threaded hole 6 and the distance from the side surface of the flange body 1 to the connecting groove 4, and when the fastening bolt 7 is completely connected with the threaded hole 6, the fastening bolt 7 is not exposed on the flange body 1 too much.
And at least six connecting holes 3 are formed to ensure the connection tightness between the flange connecting pieces.
The utility model discloses a theory of operation: when the flange connecting piece is used, the pipe diameter of a pipeline which is connected according to needs is selected to be in threaded connection with the inner surface of a connecting pipe or in threaded connection with the outer surface of the connecting pipe, and after connection is completed. And rotating the fastening bolt to ensure that the fastening bolt is not exposed in the connecting groove, staggering the two flange connecting pieces by a certain angle, connecting the connecting block of one flange connecting piece with the connecting groove of the other flange connecting piece, screwing the fastening bolt until the bolt is not exposed on the flange body, and completely connecting the fastening bolt with the threaded hole. And then, the bolt penetrates through the connecting hole and is fixed by the nut, so that the two flange connecting pieces are completely connected.
The present invention has been described in connection with the embodiments thereof, and the description is not intended to be limiting, and the embodiments shown in the drawings are only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
