Abstract
The invention discloses a self-adaptive internal pressure sealing type water chamber. The self-adaptive internal pressure sealing type water chamber comprises a tank body (1), a cover plate (2) and a seal ring (4), wherein the open end of the tank body (1) is provided with an integral sealing surface (3) through welding or casting; the cover plate (2) used for sealing the tank body (1) is arranged in the tank body (1); the sealing ring (4) is arranged between the sealing surface of the tank body (1) and the cover plate (2). A pre-tightening sealing device (5) is arranged on the cover plate (2). The self-adaptive internal pressure sealing type water chamber can consist of multiple stroke chambers; each stroke chamber comprises the tank body (1), the cover plate (2), the sealing ring (4) and the pre-tightening device (5). The self-adaptive internal pressure sealing type water chamber has the advantages that the sealing performance is better, the structure is simpler and more reasonable, and the maintenance is simpler accordingly.
Description
Technical field
The present invention relates to a kind of fluid heat exchanger hydroecium, particularly a kind of self adaptation inner pressure sealed type hydroecium.
Background technology
Hydroecium is in fluid heat exchanger, to restrain the chamber that fluid is collected at two ends.Hydroecium is widely used on the products such as refrigeration, heating equipment, chemical industry equipment, pressure vessel and equipment.
As Figure 1-Figure 2, existing hydroecium is generally comprised of casing 1, cover plate 2, sealing surface 3, sealing ring 4 and adapter (not shown), bolt 5, nut 6 and annex (not shown) etc.Existing connected mode is on the tube sheet that hydroecium casing 1 is welded on Fixed Tube-sheet Reboiler, hydroecium cover plate 2 links together by bolt 5 and the nut 6 on hydroecium casing 1 outer wall, in order to prevent fluid leakage, between the flange form sealing surface 3 on hydroecium casing 1 and hydroecium cover plate 2, sealing ring 4 must be installed.
Fluid moves in hydroecium, generally there is very large pressure, pressure-acting is in hydroecium cover plate 2, make cover plate 2 produce the trend that departs from casing 1, in order to prevent that hydroecium cover plate 2 from departing from casing 1 and causing fluid leakage, must increase the pressure of the sealing ring 4 on the flange form sealing surface 3 that 2 pairs of cover plates are positioned at casing 1, be generally to strengthen by increasing quantity or the grade of bolt 5; The miniature deformation of while hydroecium cover plate 2 also can cause poorly sealed, and therefore in order to prevent 2 deformation of hydroecium cover plate, it is steel plate manufacture more than 30mm that hydroecium cover plate 2 generally all adopts thickness.
So just, when the hydroecium maintenance of heat exchanger, large because bolt is numerous, water box cover thickness of slab remakes into maintenance difficulty, bolt bears huge pulling force constantly simultaneously, easily causes bolt aging, forms bolt failure, causes fluid leakage, even causes security incident.
Summary of the invention
Technical problem to be solved by this invention is, not enough for prior art, provides a kind of maintenance convenient, and safe and reliable self adaptation inner pressure sealed type hydroecium.
Self adaptation in the present invention refers to " sealability adapts to automatically with the variation of pressure-bearing ", and inner pressed refers to " mainly by the internal pressure of the fluid in hydroecium, carrying out press seal ".
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of self adaptation inner pressure sealed type hydroecium, it comprises casing, cover plate, sealing ring, the open end of this casing has been wholely set sealing surface through welding or casting, the inside of casing is provided for the cover plate that envelope is established this casing, between sealing surface and cover plate, sealing ring is set.
For solving the problems of the technologies described above, the present invention also provides the second technical scheme: a kind of self adaptation inner pressure sealed type hydroecium, it comprises a plurality of strokes chamber, and each stroke chamber comprises casing, cover plate, sealing ring, the open end of this casing has been wholely set sealing surface through welding or casting, the inside of casing is provided for the cover plate that envelope is established this casing, between sealing surface and cover plate, sealing ring is set.
In order to prevent in the situation that there is no fluid, cover plate play is toppled over, and pretension sealing device is set above this cover plate.
The pressure-acting that the present invention utilizes the fluid in hydroecium to produce shows as thrust on hydroecium cover plate, and the installation site of hydroecium cover plate is arranged on instead to the inside of hydroecium casing by the outside that is arranged on hydroecium casing in the past, thrust is on hydroecium cover plate like this, generation makes cover plate be adjacent to the trend of box sealing face, the pressure of fluid is larger, the thrust producing is also larger, and sealing is also just tightr.
Compared with prior art, the beneficial effect that the present invention has is:
1, better tightness, fluid pressure is larger, and also just larger to the pressure of sealing ring, sealing is just more reliable;
2, structure is more simple, rationally, can reduce the original bolt and nut quantity of hydroecium;
3, safeguard simply, in the past because of water box cover thickness of slab weight, when Maintenance and Repair, need lift operation by special-purpose lifting apparatus, now cover sheet thickness in the present invention can significantly reduce, thickness only needs 1/3 to 1/2 of cover sheet thickness under similar pressure in the past, thereby no longer needs lifting apparatus kind equipment.

The specific embodiment
As Figure 3-Figure 4, self adaptation inner pressure sealed type hydroecium of the present invention comprises casing 1, cover plate 2, sealing ring 4, the open end of this casing 1 has been wholely set sealing surface 3 through welding or casting, the inside of casing 1 is provided for the cover plate 2 that envelope is established this casing 1, between the sealing surface of casing 1 and cover plate 2, sealing ring 4 is set.
In order to prevent in the situation that there is no fluid, cover plate 2 plaies are toppled over, and pretension sealing device 7 is set above this cover plate 2.
Self adaptation inner pressure sealed type hydroecium of the present invention also can be arranged to the form in a plurality of strokes chamber, wherein each stroke chamber comprises casing 1, cover plate 2, sealing ring 4, the open end of this casing 1 has been wholely set sealing surface 3 through welding or casting, the inside of casing 1 is provided for the cover plate 2 that envelope is established this casing 1, between sealing surface 3 and cover plate 2, sealing ring 4 is set.
