Abstract
The utility model relates to an expansion joint connection structure of an anti-abrasion corrosion-resistant pipeline, comprising an expansion joint and a slurry pipeline flange (6) which is positioned at two ends of the expansion joint. The expansion joint comprises a corrugated pipe (1) positioned at the outer layer and an anti-abrasion corrosion-resistant protection plate (2) positioned at the inner layer; two ends of the corrugated pipe (1) are provided with an inlet flange (4) and an outlet flange (8); and one end of the anti-abrasion corrosion-resistant protection plate (2) is provided with a flanged edge (9) which is fixed on the corrugated pipe (1). The expansion joint connection structure of an anti-abrasion corrosion-resistant pipeline overcomes the problems that the conventional rubber corrugated pipe has poor anti-abrasion corrosion resistance, and expansion joints are frequently replaced due to wearing through in power plants; and the expansion joint connection structure of an anti-abrasion corrosion-resistant pipeline has a simple structure, low cost, good anti-abrasion corrosion resistant performance and long service life; and with the connection structure, replacement times of equipment are reduced in a number of power plants, thereby guaranteeing the continuity and stability of production.
Description
Technical field
The utility model relates to a kind of expansion joint and connects, and more particularly it is a kind ofly to save linkage structure because of mechanical vibration with the abrasionproof corrosion resistant pipe expansion that flowing medium washes away, dielectric corrosion is arranged on the wet desulfurization system slurries pipeline 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 linkage structure is provided.
The purpose of this utility model reaches by following measure: abrasionproof corrosion resistant pipe expansion joint linkage structure, it comprises expansion joint and is positioned at the slurries piping flange at expansion joint two ends, it is characterized in that described expansion joint comprises the abrasionproof corrosion resistant backplate that is positioned at outer field bellows and is positioned at internal layer, there are suction flange and outlet(discharge) flange in the two ends of described bellows, one end of abrasionproof corrosion resistant backplate has flange, and flange is fixed on the bellows; Be connected by bolt assembly between the slurries piping flange of one end and the suction flange, in the slurries piping flange, elastometric lining arranged, between the flange of abrasionproof corrosion resistant backplate and slurries piping flange, flange gasket is arranged; Be connected by bolt assembly between the slurries piping flange of the other end and the outlet(discharge) flange, in the slurries piping flange, elastometric lining arranged, between bellows and slurries piping flange, flange gasket is arranged.
In technique scheme, described suction flange is positioned at the flange inboard of abrasionproof corrosion resistant backplate one end.Described abrasionproof wear plate is for adopting wear-resisting type glass fibre reinforced plastics backplate.
The utility model abrasionproof corrosion resistant pipe expansion joint linkage structure is simple, 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.
