Description

Anticorrosion water-fast non-metal expansion joint

Technical field the utility model relates to a kind of anticorrosion water-fast non-metal expansion joint, relates in particular to the non-metal expansion joint in fields such as a kind of be widely used in electric power that is positioned at wind, cigarette, pipeline, chemical industry.

Background technique in the prior art, more existing pipeline expansion joints, Chinese patent ZL03255273.4 disclosed " with the complex corrugated pipe expansion joint of shared outer sleeve " is made of bellows, outer sleeve, filler baffle ring, throat ring, trim ring and guide plate etc., its structure is comparatively complicated, so fabricating cost is higher, thereby need to improve.

The summary of the invention the purpose of this utility model is to provide a kind of simple in structure, dismounting and cleaning is convenient and can acid resistant alkali etc. multiple Korrosionsmedium and water-fast non-metal expansion joints.

In order to achieve the above object, the utility model provides following technological scheme: design a kind of anticorrosion water-fast non-metal expansion joint, be positioned at the wind and smoke pipeline enclosure, this expansion joint is made of metal frame (1), nonmetal covering (2) and scupper (4), the integral body of metal frame (1) ringwise, metal frame (1) is gone up nonmetal covering (2) fixedly is housed, and has scupper (4) under the nonmetal covering (2).Described nonmetal covering (2) is generally used material such as the relatively large and corrosion-resistant plastic of thermal expansion coefficient, rubber, and this expansion joint can be used as the anticorrosion water-fast pipe joint that contains Korrosionsmediums such as acid, alkali that temperature is lower than the medium dew point.

Nonmetal covering of the present utility model (2) is the outside arc that of encircleing.Be beneficial to covering and be out of shape because of temperature variation, using effect is better.

Nonmetal covering of the present utility model (2) is connected by bolt with the flange of metal frame (1), and pressure ring (5) is arranged on the periphery of nonmetal covering (2).Be convenient to dismounting and change nonmetal covering (2).

Scupper of the present utility model (4) locates to be equipped with connecting tube (6), and connecting tube (6) is flange with the nonmetal covering (2) at its place and is connected, and side has marine glue coating (3) within the nonmetal covering (2) herein.Be convenient to dismounting and change nonmetal covering (2) and connecting tube (6), marine glue coating (3) has reached water-fast purpose effectively.

Metal frame of the present utility model (1) is connected with the wind and smoke pipeline by (8) connection of anti-flange or welding.That is to say that metal frame (1) is connected by flange flange (7) with the connecting end of wind and smoke pipeline or welds, when flange connects, sealing gasket (9) is housed in the flange.

Compared with prior art, the utlity model has simple in structure, use and easy accessibility, long service life and advantage such as applied widely, can be widely used in industries such as chemical industry, electric power, metallurgy, medicine and weaving.
