Abstract
The invention discloses a telescopic flange-free connecting air pipe. The telescopic flange-free connecting air pipe comprises a first air pipe with one end welded with an external connecting pipe, and a second air pipe with one end welded with an internal connecting pipe, wherein a circular groove is formed in the external diameter of the internal connecting pipe; a rubber sealing ring is mounted on the circular groove. The telescopic flange-free connecting air pipe has the advantages that the telescopic flange-free connecting air pipe is adjustable in length, convenient to mount and manufacture, low in requirement on precision, and convenient for workers to operate, shortens the construction time and improves the work efficiency.
Description
Technical field
The present invention relates to technical field of pipeline connection, be exactly specifically can reduction flangeless conjunction airduct.
Background technology
Present pipeline is all that usage wheel disc connects, and cannot loosen after connection, and distance cannot regulate, so that the required precision of the length of pipeline is higher, gives to manufacture and install and brings very big difficulty.
Summary of the invention
It is an object of the invention to design a kind of wind pipeline adjustable in length, it is simple to install the accuracy of manufacture without too high request can reduction flangeless conjunction airduct.
The present invention can reduction flangeless conjunction airduct, be welded with outer connecting pipe including the first airduct one, of the second airduct is welded with inner connection tube, and inner connection tube external diameter is provided with a circular groove, equipped with rubber seal on circular groove.
Two seals for pipe joints regulate and are achieved in that in the outer connecting pipe that the inner connection tube road 3 of the second airduct 1 loads the first airduct 2, then rubber seal 5 just seals the internal diameter of outer connecting pipe 4 and the external diameter of inner connection tube 3.
The present invention can the advantage of reduction flangeless conjunction airduct be adjustable in length, it is simple to installing the accuracy of manufacture without too high request, operative is convenient, shortens the engineering time, improves work efficiency.
Accompanying drawing explanation
Fig. 1 is can reduction flangeless conjunction air duct structure schematic diagram.
Detailed description of the invention
According to Fig. 1, one can reduction flangeless conjunction airduct, be welded with outer connecting pipe 4 including the first airduct 2 one, of the second airduct 1 is welded with inner connection tube 3, and inner connection tube 3 external diameter is provided with a circular groove, equipped with rubber seal 5 on circular groove.
Two seals for pipe joints regulate and are achieved in that in the outer connecting pipe that the inner connection tube road 3 of the second airduct 1 loads the first airduct 2, then rubber seal 5 just seals the internal diameter of outer connecting pipe 4 and the external diameter of inner connection tube 3.
