Abstract
The utility model relates to a high alloy lock fastener protective tile which is used for preventing circulating fluidized bed boilers, furnace in fluid beds and other pipe burying or water screen tubes from wearing. The protective tile is made of high alloy material with good wear-resisting property, the inner surface of the protective tile is coated with heat conducting filler and the cross section of the protective tile is provided with lock fastener structures. A slinger ring used for installing the protective tile and pipelines together is provided with two dividing parts, the two dividing parts can be combined into a semicircular structure, both ends of each individual circular arc shape are both provided with a lock fastener structure and the lock fastener is provided with a bolt hole and is fastened by a bolt when installed. Owing to adopting the lock fastener connection mode, the utility model solves the sealing-off problem of welding tightening in the prior art, and the utility model has good wear-resistance, long service life and good heat transfer property.
Description
Technical field
The high alloy snap close that the utility model relates to pipe layings such as CFBB, fluidized bed furnace or the anti-wear usefulness of water screen tube protects watt.
Background technology
In fluidized system, the wear phenomenon especially severe of pipe fitting, traditional wear-resistant method is to adopt heat-resistance stainless steel abrasionproof cover, the metal abrasionproof cover of this type, creep temperature wears no resistance below 750 ℃, easily torsional deformation.Afterwards, adopt the way of the wear-resistant powder of spraying, operation easier is big, is prone to Lou spray, still has the phenomenon of heating surface wear, and the site operation difficulty.Adopt nonmetal carbonization silicon to hang brick in addition and water the wearability that method that material feeding conducts heat realizes pipe fitting, but the conductivity of heat extreme difference, and construction is complicated, cost is high, come off easily in using, and the abrasionproof performance is also undesirable.
At present, solving the anti-wear property of pipe laying such as CFBB, fluidized bed furnace or water screen tube, is to be welded with some band steel sheets to solve wear problem around pipe.But, the wearing and tearing of boiler such as CFBB, fluidized bed furnace are quite serious, generally speaking, pipe laying or water screen tube are the longest three months the shortest 15 days of service time, promptly leaked by mill, and, owing to be to be welded to connect between two semicircles of protecting watt, protect watt and do not snap easily, come off, be out of shape, had a strong impact on the normal operation of boiler.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of easy for installation, abrasion resistance good, good heat conductivity, no pad, indeformable in the use, can make pipe fitting strengthen the doubly above high alloy snap close of 5-8 service life and protect watt.
The high alloy snap close protects watt, it is characterized in that: protecting watt is to be made by the good high alloy material of anti-wear performance, scribbles heat filling protecting a watt inner surface, is provided with buckle structure protecting on watt section; In order to will protect watt the suspension ring that are installed together with pipe fitting are the two parts that separate, and the two parts that separate lump together into semi-circular structure, are equipped with buckle structure at each independent circular arc type two ends, are provided with bolt hole on snap close, use bolted during installation.
The utility model has solved the fixing problem of snapping of welding in the prior art owing to adopt the connected mode of snap close, and anti-wear performance is good, long service life, good thermal conduction.
Description of drawings
Fig. 1 is the structural representation that the high alloy snap close protects watt.
The specific embodiment
The high alloy snap close protects watt, and protecting watt is to be made by the good high alloy material of anti-wear performance, scribbles heat filling 7 protecting watt 5 inner surfaces, is provided with snap close 6 structures on watt section protecting; In order to will protect watt the suspension ring 3 that are installed together with pipe fitting are the two parts that separate, and the two parts that separate lump together into semi-circular structure, are equipped with snap close 1 structure at each independent circular arc type two ends, are provided with bolt hole on snap close, fastening with bolt 2 during installation.
In use, will protect frayed that watt is installed in pipe fitting, with the snap close 4 of suspension ring both sides respectively with the snap close fastening of protecting on watt section, then the snap close on two suspension ring is got final product with bolting.
In use, will protect frayed that watt is installed in pipe fitting, with the snap close of suspension ring both sides respectively with the snap close fastening of protecting on watt section, then the snap close on two suspension ring is got final product with bolting.
