Abstract
The utility model relates to a floating head heat exchanger pipe bunch pressing device which is formed by welding a flange and a rolled ring. The floating head heat exchanger pipe bunch pressing device comprises a pipe bunch cylinder body flange and a pipe plate, the flange is fixedly fastened with the pipe bunch cylinder body flange through a bolt, and the rolled ring is fixedly fastened with the pipe plate through a seal ring. A sealing piece is arranged between the flange and the pipe bunch cylinder body flange. The floating head heat exchanger pipe bunch pressing device is simple in structure, reduces material consumption and reduces cost; is good in sealing performance and especially obvious in effect for high-pressure equipment; is beneficial to observing the leakage conditions of a floating head heat exchanger pipe bunch, only in need of one-time bolt fastening, shortens pressing time and improves the working efficiency.
Description
Technical field
The utility model belongs to mechanical equipment technical field, specifically, relates to a kind of floating head heat exchanger tube bank pressure device.
Background technique
Existing floating head heat exchanger tube bank pressure device, its structure as shown in Figure 2, comprises three flanges and two pipe nipples, adopting tube sheet to contact the mode compressed with trim ring with cushion rubber seals, its manufacturing process is complicated, it is more to manufacture consumptive material, and needs fastening twice bolt while using, and working efficiency is very low.
The model utility content
For solving the problems of the technologies described above, the utility model proposes a kind of simple in structure, consumptive material is few, the novel floating head heat exchanger of good airproof performance tube bank pressure device.
The technical solution of the utility model is: a kind of floating head heat exchanger tube bank pressure device, and it is welded by flange and forging-ring; Described floating head heat exchanger tube bank comprises tube bank shell flange and tube sheet, and flange tightens up by bolt and pipe tube bank shell flange, and forging-ring tightens up by seal ring and tube sheet.
Be provided with Sealing between described flange and tube bank shell flange.
During use: after at first pressure device and floating head heat exchanger tube bank tube sheet cylindrical being aligned, by bolton, tube sheet cylindrical and forging-ring relatively move, and are with the dynamic seal ring scrolling realization to seal.
The beneficial effects of the utility model are:
1, the utility model is simple in structure, compared to existing frock, has greatly reduced materials'use, has reduced cost;
2, the utility model good seal performance, particularly evident for the high-tension apparatus effect.
3, the utility model is concordant with tube sheet, is conducive to observe the leak case of floating head heat exchanger tube bank, only need carry out bolton one time, has shortened suppressed time, has improved working efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of prior art.
Wherein, 1, flange; 2, forging-ring; 3, tube bank shell flange; 4, tube sheet; 5, bolt; 6, seal ring; 7, Sealing.
Embodiment
Illustrate the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, the utility model is welded by flange 1 and forging-ring 2; The floating head heat exchanger tube bank comprises tube bank shell flange 3 and tube sheet 4, and flange tightens up by bolt 5 and tube bank shell flange 3, and forging-ring 2 tightens up by seal ring 6 and tube sheet 4.
Be provided with Sealing 7 between described flange 1 and tube bank shell flange 3.
During use: after at first pressure device and floating head heat exchanger tube bank tube sheet cylindrical being aligned, fastening by bolt 5, tube sheet cylindrical and forging-ring 2 relatively move, and are with dynamic seal ring 6 scrolling realization to seal.
