Abstract
The utility model relates to an antiwear corrosion-resistant pipeline expansion joint which comprises an annular bellows (1) located on the outer layer and an annular antiwear wear-resistant guard plate (2) located on the inner layer of the annular bellows (1), wherein a flanging (5) is arranged at one end of the annular antiwear wear-resistant guard plate (2), and the flanging (5) and one end of the annular bellows (1) are fixed together. The antiwear corrosion-resistant pipeline expansion joint overcomes the problems that the wear resistance and the corrosion resistance of the traditional rubber bellows are bad, the expansion joint is replaced frequently caused by complete wear in some power plants, and etc. The antiwear corrosion-resistant pipeline expansion joint of the utility model has the advantages of simple structure, low cost, good antiwear corrosion-resistant performance and long practical life cycle, the replacement times of equipment in the power plants are decreased, and the continuity and the stability of production are guaranteed.
Description
Technical field
The utility model relates to a kind of pipe expansion joint, and more particularly it is a kind ofly to save with the abrasionproof corrosion resistant pipe expansion that flowing medium washes away, dielectric corrosion is arranged on the wet desulfurization system slurries pipeline because of mechanical vibration for compensation.
Background technique
Rubber expansion joint is a kind of very effective compensating element of installing and using on the desulfurization project pipeline system; the equipment that links to each other with pipeline is formed protection; it also is the weakest in a whole tubing link simultaneously, and its rubber corrugated pipe abrasion-proof corrosion-proof has determined the ride quality of whole tubing.In China, rubber expansion joint a large amount of use in the desulfurization project pipe-line system was just risen in recent years.But because comparatively coarse on manufacturing process, the anticorrosion coefficient difference of liner abrasionproof, problems such as the worn out replacing of expansion joint is frequent often appear in some power plant.Therefore, how improving rubber expansion joint inside lining sleeve abrasionproof anticorrosion is the problem that urgency is to be solved that we face.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existing rubber expansion joint, and a kind of abrasionproof corrosion resistant pipe expansion joint is provided.
The purpose of this utility model reaches by following measure: abrasionproof corrosion resistant pipe expansion joint, it is characterized in that it comprises is positioned at outer field ring bellows 1, be positioned at ring bellows 1 internal layer annular abrasionproof wear plate 2, one end of described annular abrasionproof wear plate 2 has flange 5, and described flange 5 is fixed together with an end of ring bellows 1.
In technique scheme, an end of described ring bellows 1 outside is set with suction flange 4, and the other end outside of ring bellows 1 is set with outlet(discharge) flange 3.
In technique scheme, described suction flange 4 is positioned at the end that annular abrasionproof wear plate 2 has flange 5, and described abrasionproof wear plate 2 is for adopting wear-resisting type glass fibre reinforced plastics backplate.
The utility model abrasionproof corrosion resistant pipe expansion joint is simple in structure, and cost is low, and the abrasionproof corrosion resistant performance is good, and the physical life cycle is long, has reduced the replacing number of times of some power plant to equipment, has guaranteed the continuity and the stability of producing.
Description of drawings
Fig. 1 is the structural representation of the utility model abrasionproof corrosion resistant pipe expansion joint.
1. ring bellowss among the figure, 2. abrasionproof wear plate, 3. outlet(discharge) flange, 4. suction flange, 5. flange.
Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute to qualification of the present utility model, only do for example.Simultaneously by illustrating that advantage of the present utility model will become clear more and understanding easily.
Consult Fig. 1 as can be known: the utility model abrasionproof corrosion resistant pipe expansion joint, it comprises and is positioned at outer field ring bellows 1, be positioned at ring bellows 1 internal layer annular abrasionproof wear plate 2, one end of described annular abrasionproof wear plate 2 has flange 5, and described flange 5 is fixed together with an end of ring bellows 1.The one end outside of described ring bellows 1 is set with suction flange 4, and the other end outside suit (also can make the structure that is fixed as one) of ring bellows 1 has outlet(discharge) flange 3.Described suction flange 4 is positioned at the end that annular abrasionproof wear plate 2 has flange 5, and described abrasionproof wear plate 2 is for adopting wear-resisting type glass fibre reinforced plastics (being commonly called as the FRP material) backplate.
