Abstract
The utility model relates to a spare part for a heat exchange device, in particular relates to a sealing device for a stopping and blocking component. The tube changeable sealing device regarding the utility model for a graphite heat exchanger consists of a graphite tube, a tube plate, a shell body and a sealing ring. The shell body is connected with the tube plate; the sealing ring is arranged between the graphite tube and the tube plate; the sealing ring is in an I shaped structure. The sealing ring of the utility model has the advantage of simple structure, excellent sealing effect and longer life expectancy etc.
Description
Technical field
The utility model relates to a kind of parts of heat-exchange apparatus, relates in particular to a kind of sealing device of using obturating element.
Background technology
The seal configuration of graphite heat exchange tube sheet of the prior art is more single, sealing is poor, along with heat exchanger improving constantly to the pressure requirement, requirement to the sealing property of seal is also more and more higher, so the seal of heat exchanger is normal adopt multi-sealed, though its sealing effectiveness improved owing to adopt multi-sealed, its processing technology complexity, and the inevitable corresponding raising of its cost; Also have and adopt substance to seal the structure improvement of sealing ring, as Chinese patent publication number CN2440193Y, a kind of tube-type graphite heat exchanger is disclosed, the part of tube sheet is inserted by the sealing of fluorubber cover in its graphite-pipe two ends, the fluorubber cover is hollow cylindrical, one end has circular convex, this kind design is all improved a lot the service life of sealing ring and effect, but further raising along with pressure, its sealing effectiveness is not very good, operating pressure is up to 0.55Mpa, can not finely adapt to the rapid drawdown that rises sharply of multiple condition downforce aspect compression resistance, makes its application have certain limitation.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, provide a kind of sealing effectiveness good sealing ring, it is can the fine rapid drawdown that rises sharply that has adapted under the multiple condition aspect the compression resistance, and has prolonged the life-span of sealing cushion rubber.
For achieving the above object, the utility model adopts following technical scheme: it comprises graphite-pipe, tube sheet, housing and O-ring seal, and tube sheet and housing link together, and O-ring seal is between graphite-pipe and tube sheet, and O-ring seal is " I " shape structure of hollow.
Tube sheet can adopt graphite tube plate, also can adopt fiberglass tube sheet, Stainless Steel Tubular Plates or carbon steel tube plate, because O-ring seal is a hollow structure, graphite-pipe can pass from the mesopore of O-ring seal, and the O-ring seal of " I " shape structure boss inner surface of both sides up and down contacts with the both ends of the surface of tube sheet.Because the improvement of structure, the O-ring seal of " I " shape structure boss of both sides up and down can bear bigger pressure, rise sharply or during rapid drawdown in internal pressure, can make the distortion of O-ring seal unlikely excessive, sealing effectiveness is fine, the operating temperature of heat exchanger can reach 150 ℃, and operating pressure is brought up to 1.2Mpa.
Housing is provided with flange, and tube sheet adopts bolt to be connected with the flange of heat exchanger shell, is convenient to change the parts of damage like this, has overcome in the prior art owing to adopt the connected mode of welding, not easily changeable defective.
Sealing ring of the present utility model has advantages such as simple in structure, good sealing effect, long service life.
Description of drawings
Fig. 1 is the general assembly drawing of heat exchanger;
Fig. 2 is the partial enlarged drawing of A portion.
The specific embodiment
The utility model comprises graphite-pipe 1, tube sheet 3, housing 5 and O-ring seal 2, and housing 5 links together with tube sheet 3, and O-ring seal 2 is tightly connected graphite-pipe 1 and tube sheet 3, and wherein O-ring seal 2 is " I " shape structure.
O-ring seal 2 hollow structures, the boss inner surface of O-ring seal both sides about in the of 2 of " I " shape structure contacts with the both ends of the surface of tube sheet 3, and graphite-pipe 1 passes from the mesopore of O-ring seal 2; Housing 5 is provided with flange 4, and tube sheet 3 adopts bolting to be connected with the flange 4 of heat exchanger shell, is convenient to change the parts of damage like this.Because the improvement of structure can make the operating temperature of heat exchanger reach 150 ℃, operating pressure is brought up to 1.2Mpa.
Claims (4)
1. but the sealing device of a replace tubes graphite heat exchanger comprises graphite-pipe, tube sheet, housing and O-ring seal, and housing and tube sheet link together, and O-ring seal is characterized in that O-ring seal is " I " shape structure of hollow between graphite-pipe and tube sheet.
But 2. the sealing device of replace tubes graphite heat exchanger according to claim 1, it is characterized in that O-ring seal up and down the boss inner surface of both sides contact with the both ends of the surface of tube sheet.
3. but the sealing device of replace tubes graphite heat exchanger according to claim 2 is characterized in that tube sheet adopts graphite tube plate, also can adopt fiberglass tube sheet, Stainless Steel Tubular Plates or carbon steel tube plate.
4. but according to the sealing device of claim 1 or 3 described replace tubes graphite heat exchangers, it is characterized in that housing is provided with flange, tube sheet adopts bolt to be connected with the flange of heat exchanger shell.
