Abstract
The invention relates to a pipeline union joint, and belongs to the field of pipeline connection. The pipeline union joint comprises an outer pipe, a first inner pipe, a second inner pipe and a stopping sheet, wherein the first inner pipe and the second inner pipe are arranged in the outer pipe, and the stopping sheet is arranged between the connecting end of the first inner pipe and the connecting end of the second inner pipe. The pipe union joint can connect pipe fittings with different calibers and meet the requirement for leakproofness, further can be externally connected with other devices, and therefore is wide in application range and convenient to connect.
Description
Technical field
The present invention relates to a kind of Petrochemical Pipe Joints, belong to pipeline connection area.
Background technique
Connection between siphunculus is interconnected by parts such as joints, but existing connected element is just used some simple and crude rubber to be wound around, or in joint, using glue class to practice connects, this type of connection sealing is bad, topmost problem is that the different pipe fitting of diameter cannot be interconnected.
Summary of the invention
The present invention is directed to above-mentioned deficiency a kind of Petrochemical Pipe Joints is provided.
The present invention adopts following technological scheme:
A kind of Petrochemical Pipe Joints of the present invention, comprises outer tube, inner tube one, inner tube two, blocking blade; In described outer tube, arrange inner tube one and inner tube two, between inner tube one and inner tube two connecting ends, arrange blocking blade.
Petrochemical Pipe Joints of the present invention, one end outer rim of described outer tube is provided with groove, and groove is provided with leakage proof gasket.
Petrochemical Pipe Joints of the present invention, described outer tube outer side wall is provided with buckling groove.
Petrochemical Pipe Joints of the present invention, the diameter of described inner tube one is greater than inner tube two.
Petrochemical Pipe Joints of the present invention, described buckling groove is trapezoidal.
Beneficial effect
Petrochemical Pipe Joints provided by the invention, can connect the different pipe fitting of bore, and sealing reaches requirement, and this joint outside also can connect other equipment, and application is wide, easy to connect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
