Description
Technical field
The utility model relates to a kind of instrument that checks whether tubular heat exchanger leaks, and belongs to heat transmission equipment service kit technical field.
Background technology
At metallurgy, the enterprises such as chemical industry usually will carry out cooling heat transferring to various production media, to satisfy the Technology Need in the production technology in producing.At present, known shell and tube heat-exchanger rig main body is by heat exchanger shell, the shell and tube core body, and heat exchanger shell two ends end socket forms, in the tubulation and the Medium Exchange heat of the outer different temperatures of tubulation, equilibrium temperature.Heat interchanger adopts water cooling product medium mostly, because water temperature when heat exchange raises, can separate out incrustation scale and be attached in the tubulation wall, so will add chemical agent in water, wherein principal ingredient is strong acid.Acid can be corroded the tubulation wall in long-term production run, cause its leakage, therefore need in process of production various different sizes, corresponding core body shell is surveyed and drawn and made to the heat interchanger of model, core body torn open when suspecting that it leaks and move on to as in its special core body shell, which root tube leaking water filling check outside tubulation or in the tubulation to determine, again with the corresponding metal conic plug of tubulation diameter its two ends being shut.Need in this repair process to make special-purpose leakage detection housing with the expense of same model heat interchanger about 30%, it not only causes fund idle, also will take storehouse preserves, and its disassembly process needs the tradesman to operate and hanging device, the more important thing is needs to prolong the repair time that stops production, and greatly reduces productivity effect.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple and easy leakage detection tool of tubular heat exchanger that moves heat exchanger tube formula core body, can carry out quickly and easily leakage detection of can avoiding tearing open.
The technical scheme that solves the problems of the technologies described above is:
The simple and easy leakage detection tool of a kind of tubular heat exchanger, it is comprised of tubulation plug, stopcock, tensimeter, connecting rod, push handle, the front portion of tubulation plug is cop plug, the rear portion is female sleeve interface, tubulation plug center has through hole vertically, connecting rod is cylindrical sleeve, the front end outer wall of connecting rod has the internal thread of the sleeve interface of screw thread and tubulation plug to be complementary, the stopcock of connection and manometric screw are arranged on the link rod sleeve wall, stopcock and manometric connecting screw hole are connected with the barrel bore of connecting rod, and push handle is connected to the rear end of connecting rod.
The simple and easy leakage detection tool of above-mentioned tubular heat exchanger, it is the engineering plastics material that described tubulation is inserted procephalic cop plug, two end interfaces of the tapering of cop plug and heat exchanger tube are complementary.
The beneficial effects of the utility model are:
Tubulation plug of the present utility model inserts tubulation one end, and whether by stopcock injection pressure water, can detect tubulation by tensimeter has leakage.Testing process fast, conveniently, removed from the heat interchanger of various different sizes, model has been surveyed and drawn, and the demand of making respective core body case, man-hours requirement and hanging device in expense and the disassembly process have been saved, the more important thing is and shortened stopping production repair time, guaranteed metallurgy, the continuous production time of the enterprises such as chemical industry, greatly improved productivity effect, and maintenance process is safer than in the past, easy.
