Abstract
Disclosed is a pipeline soft connection device used for the connection of the soft pipe and the hard pipe with a flange. The utility model provides a pipeline connection which is easy to be implemented and realizes the efficient connection of the soft pipe and the flange pipeline. The utility model comprises a flange pipeline, a soft pipe and a flange; the flange is sleeved on the soft pipe; the connecting end of the soft pipe is coiled with rubber strip; the soft pipe flange is fixedly connected with the flange pipeline through a bolt. The utility model has the advantages of simple structure, convenient connection and ideal application effect.
Description
Affiliated technical field
The utility model relates to a kind of pipeline and connects, and more particularly, it is used for being connected of flexible pipe and flanged (FLGD) hard tube.
Background technique
With the flange connecting tube is chemical plant method commonly used, passes the bolt hole of two ends piping flange with bolt, adds nut screwing clamping, accompanies gasket seal between two flanges.And flexible pipe is connected with hard flanged pipe in the employing flexible pipe insertion hard tube, with the soft material sealing, with iron wire flexible pipe is fixed on the hard tube between pipe, and sealing is poor, and is perishable.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides pipeline a kind of simple in structure, easy to implement to connect, and it can accomplish that flexible pipe is connected with the effective of flanged pipe.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of pipeline soft connection device comprises flanged pipe, flexible pipe, flange, and described flange is enclosed within on the flexible pipe, and described flexible pipe connects an end and twines rubber strip.
