Abstract
The utility model discloses a double-section type convenient connecting short pipe; wherein, a sleeve hole and a tapered bore are arranged at one end of a connecting pipe, and a plane butt is arranged at the other end of the connecting pipe. Two connecting pipes, two flanged discs, two cone seal rubber rings and a seal ring are sleeved on the two sections of connected pipes. The sleeve hole of each section of connecting pipe is provided with a cone seal rubber ring. A male tab, which can be inserted into the sleeve hole of the connecting pipe, is arranged on the flanged disc, and the butt of the male tab is propped on the cone seal rubber ring. The two sections of connecting pipes are connected with the two flanged discs as a whole by a connecting bolt. The utility model has the advantages that no additional pipe is needed to connect the two sections of pipes, and the connecting operation is convenient. The utility model is more particularly applicable to leakage repairing and connection of large type pipes.
Description
Technical field:
The utility model relates to the convenient connection short tube of a kind of double-joint type, belongs to pipeline connection fittings technical field.
Background technique:
At present, pipeline connecting tube of the prior art, in use, generally all will be after increasing by a joint connecting tube between the connected pipeline again, could connect as one with the pipeline of connecting tube with connected pipeline and increase, therefore this connecting tube is very inconvenient in use.
Summary of the invention:
The purpose of this utility model is: providing a kind of need not increase that new pipeline can connect the 2-section pipe road and the attended operation convenient connection short tube of double-joint type easily, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises connecting tube (1), it is characterized in that: the trepanning a and the taper hole b that are provided with the cone seal cushion rubber (3) of to pack at an end of connecting tube (1), end face at the other end of connecting tube (1) is flat end face c, and all be provided with bolt hole d on the two ends connecting plate of connecting tube (1), connecting bolt (4) can connect as one two joint connecting tubes (1) and flange plate (2) by bolt hole d; On connected pipeline (6), be with two joint connecting tubes (1), two flange plate (2), two cone seal cushion rubbers (3) and a seal ring (5), a cone seal cushion rubber (3) all is housed in the trepanning a of every joint connecting tube (1), and between the other end flat end face c of connecting tube (1), be lined with seal ring (5), on flange plate (2), be provided with the boss e in the trepanning a that can inject connecting tube (1), the end face of boss e is against on the cone seal cushion rubber (3), and two joint connecting tubes (1) and two flange plate (2) connect as one by connecting bolt (4).
Owing to adopted technique scheme, the utility model compared with prior art, the utlity model has need not increase that new pipeline can connect the 2-section pipe road and attended operation advantage easily.During use, on connected pipeline (6), put earlier two joint connecting tubes (1), two flange plate (2), two cone seal cushion rubbers (3) and a seal ring (5) respectively, and cone seal cushion rubber (3) is contained among the trepanning a of connecting tube (1), seal ring (5) pad is saved between the other end flat end face c of connecting tubes (1) two, then the boss e of flange plate (2) is injected in the trepanning a of connecting tube (1) and be against on the cone seal cushion rubber (3), save connecting tubes (1) and two flange plate (2) with connecting bolt (4) with two and connect as one.The utility model is particularly suitable for the mending-leakage of large-scale pipeline and connects using.
