Abstract
The utility model provides a hoop device for managing cracking leakage of a circumferential weld of an evaporator barrel. The utility model is characterized in that the hoop device for managing the cracking leakage of the circumferential weld of the evaporator barrel consists of a plurality of arc-shaped hoops which can be encircled into a circular ring; the inner sides of the hoops are respectively provided with a cavity; and the hoops are respectively provided with a plurality of threaded holes. When installation is performed, the cavities of the hoops cling to the barrel in the manner of being over against the leaked weld of the barrel; after the cavities of the hoops are compressed tightly, the heads and the tails of the hoops are mutually connected and firmly welded; then, high temperature-resistance packing materials are respectively injected into the cavities of the hoops at high pressure through glue injecting holes on the hoops; the glue injecting holes are blocked by bolts after the packing materials are injected, and thus, the materials in the barrel can be effectively prevented from leaking. The device is simple in structure and convenient in installation, and the negative influence brought to an equipment body and the metal of an original weld by adopting a grinding and repair welding mode can be effectively avoided. Under the condition of not influencing the service performance of equipment, the materials can be effectively prevented from leaking from the cracked weld of an evaporator, and the weld is effectively isolated from alkali liquor to avoid the phenomena that the cracked weld is expanded and new weld cracking is generated.
Description
Technical field
The utility model relates to a kind of anchor ear device of weld cracking leakage improvement, is applicable to evaporator tube girth joint cracking Leakage Treatment.
Background technology
The cracking position that existing evaporimeter weld cracking Leakage Treatment mainly is a butt welded seam adopts the mode of polishing repair welding to handle.Because employed evaporimeter volume is generally bigger in producing, inside is equipped with the tube bank of hundreds of root, if large-area repairing and heat treatment are carried out in the scene, causes barrel distortion easily, and influence is changed with the tube bank of finisher, so difficulty is bigger.In addition since in the actual production evaporimeter can not withdraw from production for a long time, so the overhaul of the equipments time ratio is shorter, is basically simply to polish just directly to come into operation after the repair welding.The processing owing to do not eliminate stress, there is residual stress in postwelding, and evaporimeter comes into operation the back weld seam because stress corrosion still can continue the cracking leakage.
The utility model content
The purpose of the utility model provides a kind of weld leakage of filled type and handles the anchor ear device; Under the situation that does not influence the equipment serviceability, can effectively stop material from the weld seam of evaporimeter cracking, to leak; And effectively weld seam and alkali lye are kept apart the weld seam of avoiding ftractureing expansion and new weld cracking occurs.
The technical scheme that the utility model is taked is:
A kind of evaporator tube girth joint cracking leakage improvement anchor ear device, it is characterized in that: be made up of the some arc anchor ears 3 that can surround an annulus, cavity 6 is established in anchor ear 3 inboards, and has some screwed holes 4.Some arc anchor ears 3 are welded as a whole.
During installation the anchor ear cavity being leaked weld seam over against cylindrical shell is close on the cylindrical shell; After compressing with anchor ear headtotail firm welding; Inject resistant to elevated temperatures packing material through the gum-injecting port on the anchor ear toward anchor ear cavity inner high voltage then, packing material injects the back and with bolt gum-injecting port is blocked.Because the weld seam of cracking is filled up by the packing material that high pressure injects, effectively stoped the leakage of material in the cylindrical shell.
Adopt the described weld leakage of the utility model to handle the anchor ear device, the material from leakage in the time of can being used for shell-and-tube evaporator and heat exchanger cylindrical shell girth joint cracking is handled.This apparatus structure is simple and be convenient to install, and can effectively avoid the adverse effect to apparatus body and former weld metal that adopts polishing repair welding processing mode to be brought.Under the situation that does not influence the equipment serviceability, can effectively stop material from the weld seam of evaporimeter cracking, to leak, and effectively weld seam and alkali lye kept apart, the weld seam of avoiding ftractureing is expanded and new weld cracking occurred.
Description of drawings
Fig. 1 is the system configuration sketch map of the utility model.
Fig. 2 is the structure chart that the utility model weld leakage is handled the anchor ear device.
Fig. 3 is the A-A profile of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Among Fig. 1, Fig. 2 and Fig. 3, weld seam 2 is the girth joints on the evaporator tube 1, and the cavity 6 that establish anchor ear 3 inboards faces weld seam 2 and compresses and be installed on the cylindrical shell 1; Arc anchor ear 3 is established some; Can surround an annulus, between the anchor ear 3 through being welded to connect, shown in weld seam among Fig. 15; Install the back and inject resistant to elevated temperatures packing material, with corresponding bolt screwed hole 4 is sealed at last through screwed hole 4 high pressure that have on the anchor ear 3.Anchor ear 3 inboard cavitys 6 are filled up by the packing material that high pressure injects with the weld seam that ftractures, and have effectively stoped the leakage of material in the cylindrical shell.
