Description
Technical field
The utility model relates to a kind of elbow, is specifically related to the wear-resisting elbow bend of a kind of buffering type.
Background technique
The characteristics of this material of cast stone elbow are frangible, crackings, and the wear surface knapsack, wall thickness-millimeter, and the nearly millimeter that has, behind the inboard short time worn-off cracking, material is along with wearing and tearing laterally in the slit, and its life-span also just has only an overhaul phase.And often there is pore inside, easily stays hidden danger, in case worn out, the scene can't be repaired.
Cast steel, abrasion resistance alloy elbow are widely used in the abrasionproof field, and its manufacturing process is simple relatively.But because the limitation of the performance of material own and the restriction of technology, the surface hardness of cast steel material approximately.The elbow time of putting into operation with its manufacturing is not grown with regard to worn out situation.In addition, the cast steel duct thickness is big, and is very heavy, and the carbon content height, and weldability is poor, needs on-the-spot butt welded seam heat treatment, brings sizable difficulty for on-the-spot installation and maintenance.
This process using of centrifugal pressure casting composite ceramics is mainly utilized material self chemical reaction from the method moulding that spreads centrifugal pressure casting, and the heat release burning produces high temperature, spreads the technology of synthesizing novel substance in the process at combustion wave.The Ceramic Composite pipe internal surface of this kind method moulding displaces ceramic layer, compare with carbon steel, manganese steel steel pipe, wear-resisting property is improved to some extent, but on average be not no more than ℃ because the temperature of reaction is high, reaction time is short, the aluminium oxide that restores also rests on low temperature phase β-AlO, can not be converted to high temperature phase α-AlO transition temperature and surpass ℃.Be both aluminium oxide, but as far apart as heaven and earth on performances such as intensity, hardness and density between high temperature phase alumina and the low temperature phase alumina.Because the reaction time is short, low temperature phase alumina and molten iron centrifugation are not thorough, cause that ceramic layer is not fine and close, loose particles, hardness be low.And the technology of centrifugal pressure casting composite ceramic tube has determined to be not suitable for doing elbow and CONCENTRIC REDUCER, under the ordinary skill condition, composite ceramic tube can only be made straight tube-like, make bend pipe or CONCENTRIC REDUCER, straight tube must be divided into the plurality of sections welding, elbow after the moulding and CONCENTRIC REDUCER inwall are not streamlined structures, hinder mass transport, and reduction equipment is exerted oneself.Simultaneously, the stoneware pipe that this kind technology is produced, microfissure is many, and matter is crisp frangible, and local shedding lost efficacy easily, and can't repair after coming off.
Wear-resistant bend is with high temperature resistant powerful viscose glue alumina ceramic plate to be sticked on elbow interior wall, forms firm scuff-resistant coating after heating cure.Composite pipe has overcome the characteristics that steel pipe hardness is low, wear no resistance because of having given full play to steel strength height, good toughness, shock-resistant, good welding performance and corundum porcelain high hardness, high abrasion, anti-corrosion, good heat resistance.Therefore, composite pipe has good combination property such as wear-resisting, heat-resisting, anti-corrosion.Be desirable wear-resisting, anti-corrosion elbows such as delivery of particulate material material, grinding, Korrosionsmedium.But the not shock resistance of lined ceramics sheet that this kind product adopts is frangible under impact force action.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art and provides a kind of wear-resistant, the buffering type elbow bend that can cushion to greatest extent.
The purpose of this utility model is such realization: comprise inlet tube, outer pipe with the inlet tube vertical connection, be arranged on the buffer cavity of inlet tube and outer pipe connection place, described buffer cavity is the inner chamber body that is surrounded by cylindrical inner tube and the inner tube plug that is welded on cylindrical inner tube two ends, this cylindrical inner tube and inlet tube and the equal vertical connection of outer pipe, position over against inlet tube and outer pipe in buffer cavity is provided with first layer cushion plate and the second layer cushion plate that is parallel to each other, and all is being filled with buffering material one between first layer cushion plate and the second layer cushion plate and between second layer cushion plate and the buffer cavity.
The outer cover of described buffer cavity is equipped with the cylindrical outer skin pipe that positions by locating stud, the two ends of this cylindrical outer skin pipe are welded with the external pipe plug, be filled with buffering material two between external pipe and inner tube, described inlet tube and outer pipe are communicated with buffer cavity after passing external pipe.
Described inlet tube all is connected with external pipe by the mode of welding with outer pipe.
Described inlet tube and outer pipe all extend into buffer cavity inside.
Described inlet tube and outer pipe all are communicated with buffer cavity by the mode of welding.
Described first layer cushion plate and second layer cushion plate all are fixedly installed in the buffer cavity by the mode of welding.
Described buffering material one and buffering material two all adopt limestone material.
The utlity model has following advantage: this product materials is simple, utilize the material of carrying in two block plates and the pipeline to serve as shock absorber, prove that in practice this product can satisfy the conveying requirement of limestone system, reach the 4-6 month working time, even the longer time.Guarantee the stable operation of desulphurization system, and then guaranteed safety, the stable operation of whole unit.And the price of this product is than cheap many, economical and practical of product of the same type.
