Abstract
The utility model discloses a self-sealing structure of a pressure container. The structure comprises a container body and a cover body, an opening of the container body is pressed on the cover body, and a sealing ring is arranged on the pressure bearing surface. According to the self-sealing structure of the pressure container, although bolts are used for connecting, the bolts are not used for bearing tension produced by internal pressure but ensures that the cover body does not fall into the pressure container due to internal negative pressure of the container and gravity of the cover body; the pressure of the pressure container is completely borne by a part which is formed by mutually superposing the cover body and the container body and used for bearing the pressure, so that the stress of the cover body and the container body is uniform and dispersed, and the pressure bearing capacity of the pressure container is more than two times higher than that of a common pressure bearing container; and the structure also has an advantage that a good sealing effect is achieved when the sealing ring in the pressure bearing surface is compacted together with increment of the internal pressure.
Description
Technical field
The utility model relates to a kind of pressurized container self sealing structure, a kind of specifically pressurized container such as reaction kettle, pressure-bearing tank body, high-pressure bottle etc. of bearing.
Background technique
The high pressure resistant vessel structure of existing technology all is that enclosing cover is buckled in the position that is employed in the lid mouth basically, with bolt lock sealing is carried out in the connection mouth position of flange arrangement then.In this structure of existing technology, the internal pressure of container is in fact all sealed by lock bolt, and when the pressure of internal tank was high more, the pulling force that bolt bore was just big more.And the problem of reality is; In the process of tightening; (fastening) degree of tightening of different bolts is impossible the same; Pulling force that other bolts bear is little so the pulling force that also bears with regard to the bolt that has caused having is big, and this just causes wherein a part of bolt prior to other bolt failures easily, thereby causes the inner bearing capacity of whole pressure resistant vessel to descend.
Another defective of said structure is, pressure inside is big more, is not easy sealing more, because pressure is big the time, clamping bolt can produce micro-strain, adopts the pressure on the Stamping Steel Ribbon that bolt compresses to reduce so, so sealing effect will reduce.
And, promptly adopt the screw thread connection of screwing to the screwing hermetic structure that pressurized container adopts.Such structure can only be applicable to less aperture position, and opening must be that circle is just passable, and this has just seriously limited the structural design of pressurized container.And know that according to the claimant opening of containers such as present large-size reactor, hydraulic reservoir mostly adopts flange arrangement to seal.
The model utility content
The purpose of the utility model provides a kind of pressurized container self sealing structure that can bear high pressure.
The purpose of the utility model is to realize through following technological scheme:
A kind of pressurized container self sealing structure comprises vessel and lid, and the opening of said vessel is pressed on the lid, and pressure-bearing surface is provided with seal ring.
Link position at vessel and lid is provided with briquetting, and briquetting is connected with lid through bolt, and the non-bolt connecting end of briquetting is arranged on the vessel.
Further design is, said briquetting is embedded on the surface of vessel and lid, makes the surface of vessel and lid keep smooth.
In vessel that lid is packed into, selectable design is that said lid is ellipse, rectangular, square or hexagon.
The disclosed pressurized container self sealing structure of the utility model; Though also there is bolt to connect; But the effect of bolt is not to bear the pulling force that internal pressure produces, and guarantees that just lid can not fall into pressurized container inside owing to internal tank negative pressure and the action of gravity of self, and the pressure-bearing of pressurized container is leaned on the overlapped part of bearing pressure of lid and vessel fully; The stressed of them is even and dispersion like this; Bearing capacity is than the bearing capacity of common pressure resistant vessel greatly at least more than the twice, and this spline structure also has a good advantage to be, along with the increase of internal pressure; The inner seal ring of pressure-bearing surface also can further be compressed, and will produce better sealing effect like this.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural drawing of the described pressurized container self sealing structure of the utility model embodiment.
Fig. 2 is the structural drawing of the described pressurized container self sealing structure of the utility model embodiment.
Embodiment
As shown in Figure 1, the described pressurized container self sealing structure of the utility model embodiment comprises vessel 1 and lid 2, and the opening of said vessel 1 is pressed on the lid 2, and pressure-bearing surface is provided with seal ring.
Link position at vessel 1 and lid 2 is provided with briquetting 3, and briquetting 3 is connected with lid 2 through bolt, and the non-bolt connecting end of briquetting 3 is arranged on the vessel 1.
As shown in Figure 2, said briquetting 2 is embedded on the surface of vessel 1 and lid 2, makes the surface of vessel 1 and lid 2 keep smooth.
In vessel 1 that lid 2 is packed into, selectable design is that said lid 2 is ellipse, rectangular, square or hexagon.
The disclosed pressurized container self sealing structure of the utility model; Though also there is bolt to connect; But the effect of bolt is not to bear the pulling force that internal pressure produces, and guarantees that just lid can not fall into pressurized container inside owing to internal tank negative pressure and the action of gravity of self, and the pressure-bearing of pressurized container is leaned on the overlapped part of bearing pressure of lid and vessel fully; The stressed of them is even and dispersion like this; Bearing capacity is than the bearing capacity of common pressure resistant vessel greatly at least more than the twice, and this spline structure also has a good advantage to be, along with the increase of internal pressure; The inner seal ring of pressure-bearing surface also can further be compressed, and will produce better sealing effect like this.
