Abstract
The utility model provides an inflating tool for hunting leaks of a tube-type heat exchanger. Screw holes are distributed uniformly and spaced equally between an outer periphery of a side of a connection flange and an axis. Fastening screws go through the screw holes of the connection flange and connect the connection flange with a barrel flange of the heat exchanger. A silicon seal is disposed in a gap between the connection flange and a floating head tube plate of the heat exchanger. One side of a sealing flange extends outward to form a sealing boss. The sealing boss can be rightly snapped into the connection flange to abut against the silicon seal. The connection flange and the sealing flange are connected fixedly through screws. By using the inflating tool for hunting the leaks of the tube-type heat exchanger in the utility model, the leaks of the tube-type heat exchanger can be found timely and the damaged heat exchanging tubes can be replaced, thereby guaranteeing the normal and safe running of the production.
Description
Technical field
The field of tool of using during the utility model belongs to ME and detects especially relates to a kind of tubular heat exchanger and suppresses the instrument of leaking hunting.
Background technology
Because there are defective in corrosion or tube product itself, tubular heat exchanger the heat exchanger tube leakage problem occurs through regular meeting in use for some time, need search the leak point of tubulation.Will be in the prior art with the begining to crop up and raise the nose above water to breathe pipe and emit and disassemble of heat interchanger two ends, begin to crop up remove after, whole tube bank is in quick condition, can't suppress leak test.
Summary of the invention
The problem that the utility model will solve provides a cover frock, is used for fixing the tube bank that is in quick condition, and makes it to be in sealing state, suppresses then and leaks hunting.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: provide a kind of simple in structure, easy to use and practical tubular heat exchanger to suppress the frock of leaking hunting; Be characterized in: be uniformly distributed with screw with the axle center equidistance on the outer rim of joint flange one side, through holding screw pass the joint flange outer rim screw can be affixed with the heat interchanger shell flange; O-ring seal is put between the slit of joint flange and heat exchanger floating head tube sheet; Seal flange one epitaxial lateral overgrowth stretches out a seal convexity, just in time can snap in the said joint flange, props up said O-ring seal, by affixed said joint flange of screw and said seal flange; Said joint flange outer rim is provided with a plurality of dismounting screws, also is provided with a plurality of dismounting screws on the said seal flange.
Said tubular heat exchanger is suppressed the frock of leaking hunting, and it is characterized in that: be provided with three dismounting screws respectively at least on the outer rim of said joint flange He on the seal flange.
Described tubular heat exchanger is suppressed the frock of leaking hunting, and it is characterized in that: with the affixed said joint flange of studs and the said seal flange of band nut.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, make to tubular heat exchanger suppress that the work of leaking hunting is convenient to be carried out, time saving and energy saving; This frock simple in structure, practical and convenient, processing cost is low.

Embodiment
As shown in Figure 1, the utility model frock characteristics are: be uniformly distributed with screw with the axle center equidistance on the outer rim of joint flange 1 one sides, through holding screw pass joint flange 1 outer rim screw can be affixed with heat interchanger shell flange (figure is last not to be marked); O-ring seal 3 is put between the slit of joint flange 1 and said heat exchanger floating head tube sheet 7; Seal flange 2 one epitaxial lateral overgrowths stretch out a seal convexity 21, just in time can snap in the said joint flange 1, prop up said O-ring seal 3, by affixed said joint flange 1 of screw and said seal flange 2; Said joint flange 1 outer rim is provided with three dismounting screws 11 that are uniformly distributed with the axle center equidistance, also is provided with three dismounting screws 22 that are uniformly distributed with the axle center equidistance on the said seal flange 2.
The course of work of the utility model embodiment: be enclosed within joint flange 1 on the floating tube sheet 7 of heat interchanger; Because joint flange 1 and floating tube sheet will form sealing surface 7 future; So the gap is less; Just must overlap during installation, joint flange 1 docks with the heat interchanger shell flange, on each screw of joint flange 1 outer rim, all puts on bolted.Between the slit of joint flange 1 and floating tube sheet 7, put into O-ring seal 3 afterwards, and make O-ring seal be put into the working position with blunt instrument.At this moment put seal flange 2, a face joint flange 1 of seal convexity 21 and the slit between the floating tube sheet 7, the position of promptly putting O-ring seal 3, the studs 4 of screwing in a week, and fastening with nut 5, make O-ring seal 3 distortion reach the purpose of sealing.
During the dismounting frock, lay down nut 5 earlier, be screwed in the dismounting screw 22 of seal flange 2 correspondences with bolt then, evenly tighten successively, seal flange 2 is withdrawed from.Then dismantle again all bolts between joint flange 1 and heat interchanger shell flange, and be screwed in the joint flange 1 corresponding dismounting screw 11 with bolt, and tighten successively, make joint flange 1 slowly break away from floating tube sheet 7.
Through using this frock, in time found the leak source of heat interchanger, changed the heat exchanger tube that damages, guaranteed to produce normal, safe operation.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
