Abstract

The utility model discloses a pipeline flow limiting device, which comprises a first taper pipe, a first straight pipe, a second straight pipe, a second taper pipe and a third taper pipe, wherein a first end of the first taper pipe is connected with a second end of the first straight pipe; a second end of the first taper pipe is connected with a first end of the second straight pipe; a first end of the first straight pipe is connected with a second end of the second taper pipe; a second end of the second straight pipe is connected with a first end of the third taper pipe; a first end of the second taper pipe is connected with a first connecting seat; and a second end of the third taper pipe is connected with a second connecting seat. According to the pipeline flow limiting device, by arranging the first straight pipe, the second straight pipe, the second taper pipe and the third taper pipe for transition at the two ends of the first taper pipe, the impact force produced to the connecting seats by instantaneously increased pressure caused by shrinkage of pipe diameter can be gradually relieved, so that the stress of the connecting seats is relatively stable, and the connection reliability of the connecting seats is guaranteed.

Description

A kind of pipeline current-limiting apparatus

Technical field

The utility model relates to a kind of conveyance conduit, particularly relates to a kind of pipeline current-limiting apparatus.

Background technique

The pipeline current-limiting apparatus is used for the transporting velocity of transportation of substances in the pipeline is limited, thereby the metering function of playing, traditional pipeline current-limiting apparatus is general direct to connect a Taper Pipe by connecting base on conveyance conduit, because the caliber of Taper Pipe is less than normal, pressure moment change was big after transportation of substances was subjected to resistance, this pressure directly acts on connecting base, and it is loosening to make that connecting base occurs easily, and connection reliability can not get ensureing.

Summary of the invention

The technical problems to be solved in the utility model provide a kind of simple in structure, can progressively reduce discharge pressure, effectively ensure the pipeline current-limiting apparatus of connection reliability.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of pipeline current-limiting apparatus, described pipeline current-limiting apparatus comprises first Taper Pipe, first straight tube, second straight tube, second Taper Pipe and the 3rd Taper Pipe, first end of described first Taper Pipe is connected with second end of first straight tube, described first Taper Pipe, second end is connected with first end of described second straight tube, first end of described first straight tube is connected with second end of described second Taper Pipe, second end of described second straight tube is connected with first end of described the 3rd Taper Pipe, first end of described second Taper Pipe is connected with first connecting base, and second end of described the 3rd Taper Pipe is connected with second connecting base.

As further improvement in the technical proposal:

The radius of described first Taper Pipe is increased progressively to second end by first end.

The radius of described second Taper Pipe is successively decreased to second end by first end.

The radius of described the 3rd Taper Pipe is increased progressively to second end by first end.

Described first connecting base is provided with some first mounting holes, and described second connecting base is provided with some second mounting holes.

The utlity model has following advantage: the utility model is by being provided for first straight tube, second straight tube and second Taper Pipe and the 3rd Taper Pipe of transition at the first Taper Pipe two ends, can progressively alleviate because caliber dwindles build-up of pressure moment and increase impact force to connecting base, make connecting base stressed mild relatively, ensured the connection reliability of connecting base.
