Description
Technical Field
The utility model relates to a pressure vessel technical field, in particular to pressure vessel's seal structure.
Background
The pressure container is a closed device which contains gas or liquid and bears a certain pressure, and is widely used in industrial production, storage and transportation links, good sealing performance is one of basic conditions required by the pressure container, and particularly, a gap is easily generated at the joint of an opening of the pressure container and a cover body under the condition of repeated opening and closing abrasion, so that pressure leakage is easily caused, and potential safety hazards are formed.
In order to ensure the tightness of the opening of the pressure container, in the prior art, a sealing groove is usually arranged at the opening or the cover body, and a rubber sealing ring is arranged in the sealing groove to improve the sealing performance of the sealing groove.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention is directed to a sealing structure of a pressure container, which can also have a better sealing effect on a high pressure container, so as to ensure the reliability and safety of the pressure container.
In order to achieve the above object, the present invention is realized by the following technical solutions:
the utility model provides a pressure vessel's seal structure, includes jar body and with jar body seal fit's lid, the medial surface of lid is equipped with the sealing ring, the external diameter of sealing ring cooperatees with the internal diameter of jar body, and the lateral surface of sealing ring is coaxial to be provided with at least one sealed annular, is equipped with annular sealed gasbag in the sealed annular, and annular sealed gasbag's air cock runs through the inboard that the sealing ring extended the sealing ring.
The utility model discloses in, jar body and with jar body seal complex lid adopt prior art to realize, for example, it is provided with on lid or the jar body and is used for sealed sealing washer etc. including being used for the locking mechanism with jar body and lid locking, all adopts the conventional means in this field to realize.
The jar body and the during operation of lid locking, the annular seal gasbag passes through air cock and jar internal portion intercommunication, when pressure vessel internal pressure risees, the annular seal gasbag expands thereupon, fill up sealed annular and with jar internal wall butt, with jar internal portion and outside isolated, prevent that the gas of jar internal portion from escaping from the gap between the lid and the jar body, and pressure in the pressure vessel is big more, the annular seal gasbag receives the influence of jar internal pressure, it is tight more with the laminating of jar internal wall, can still play fine sealed effect when high pressure.
Furthermore, the annular sealing air bag comprises an annular bag body and at least one air nozzle communicated with the annular bag body, and an annular fixing seat is arranged at one end of the air nozzle extending into the inner side of the sealing ring. Annular fixing base is fixed to be set up on the sealing ring inner wall so that annular bag physical stamina and jar internal portion normally communicate, and annular fixing base can adjust according to actual conditions with the fixed mode of setting of sealing ring inner wall.
Preferably, the annular fixing seat is bonded with the inner wall of the sealing ring, so that the air tap is tightly combined with the sealing ring, and the air tap is prevented from falling off from the sealing ring.
Preferably, the annular fixed seat is pressed on the inner wall of the sealing ring through the annular pressing sheet, so that the annular sealing air bag is convenient to disassemble and replace during subsequent maintenance.
The mode that the annular pressing sheet presses the annular fixing seat on the inner wall of the sealing ring can be realized through conventional technical means, for example, matched through holes are formed in the annular pressing sheet and the annular fixing seat, threaded blind holes matched with the through holes in the annular pressing sheet are formed in the inner wall of the sealing ring, and the annular pressing sheet and the annular fixing seat are fixedly installed on the inner wall of the sealing ring through screws.
Furthermore, a pre-sealing ring groove is arranged on the outer side face of one end, away from the cover body, of the sealing ring, and a pre-sealing rubber ring is arranged in the pre-sealing ring groove. Generally, the outer diameter of the sealing ring is matched with the inner diameter of the tank body, only a small amount of gas can enter the sealing ring groove through a gap between the outer diameter of the sealing ring and the inner diameter of the tank body, so that the pressure inside the annular sealing air bag can be ensured to be larger than the pressure inside the sealing ring groove, and the annular sealing air bag can always expand under the action of the internal and external pressure difference. In order to prevent the sealing performance between the outer wall of the sealing ring and the inner wall of the tank body from being deteriorated due to the abrasion of the cover body which is opened and closed repeatedly, and a large amount of gas enters the sealing ring groove to reduce the internal and external pressure difference of the annular sealing air bag and enable the annular sealing air bag to swell due to the abnormal expansion, the sealing ring groove and the tank body can be isolated by arranging the pre-sealing rubber ring, the internal and external pressure difference of the annular sealing air bag is ensured, and the reliability of the sealing structure is ensured.
The utility model discloses in still including other subassemblies that can make this seal structure normal use, all belong to the conventional selection in this field. Additionally, the utility model discloses in not all adopt the conventional means in this field with limited device or subassembly, for example, jar body, lid, annular utricule, air cock, the fixed group of annular, annular preforming, seal rubber circle etc. in advance all adopt conventional setting.
Compared with the prior art, the beneficial effects of the utility model are that:
this seal structure guarantees pressure vessel's sealing performance through set up the annular seal gasbag between jar body and lid, and pressure in the pressure vessel is big more, and the laminating of annular seal gasbag and jar internal wall is tight more, can still play better sealed effect when high pressure.
