Abstract

A high pressure vessel self-sealing structure comprises a manhole or access hole in a high pressure vessel. A towing ring is arranged on the external end face of the manhole or access hole. A flat cover is arranged on the internal end face of the manhole or access hole. The towing ring and the flat cover are connected through a fastener. A sealing gasket is arranged at the position where the towing ring makes contact with the manhole or access hole. Another sealing gasket is arranged at the position where the flat cover makes contact with the manhole or access hole. A movable adjusting device is arranged between the flat cover and the inner wall of the high pressure vessel in a connected mode. The high pressure vessel self-sealing structure is mainly used for sealing the manhole or access hole of the high pressure vessel, and self-sealing is realized through the pressure of a medium in the high pressure vessel. The high pressure vessel self-sealing structure has the advantages that the higher the pressure of the high pressure vessel is, the better the sealing effect will be, and can be widely applied to the field of high pressure vessels and ultrahigh pressure vessels.

Description

The high-pressure bottle self sealing structure
Technical field
The utility model relates to a kind of self sealing structure, specifically refers to a kind of manhole of high pressure, ultrahigh pressure vessel, self sealing structure of access opening of being applicable to.
Background technique
Scientific and technological progress and rapid technological improvement in view of China, modern industry is increasing for the demand of high-pressure bottle, ultrahigh pressure vessel, and the pressure of container is more high, and harmfulness is more big, its regular maintenance is with make regular check on just should be more strict, and all should arrange manhole or access opening.High-pressure bottle also is to use mechanical seal in manhole or the access opening major part of usefulness at present, rely on major diameter, high-strength bolt that enough pretightening forces are provided, it is too huge to produce bolt like this, requirement to seal element and sealing surface is also very high, bigger pretightening force simultaneously has a strong impact on working life of bolt and seal element.
The model utility content
The utility model provides a kind of high-pressure bottle self sealing structure, can effectively solve the problem that difficult sealing, seal element physical dimension are big, working life is short.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high-pressure bottle self sealing structure, comprise manhole or access opening on the high-pressure bottle, on the outside end face of described manhole or access opening draw ring is set, the internal end surface place of this manhole or access opening arranges flat cover, and described draw ring is connected by fastening piece with flat cover; Described draw ring and flat cover and described manhole or access opening contacting point are equipped with sealing gasket, are connected with the activity controlling device between described flat cover and the inner wall of high-pressure container.
Described activity controlling device comprises first, second connecting rod, and both its terminations, hinged back respectively and place the link on flat cover and the inner wall of high-pressure container hinged.
The utility model is transferred to the pretightening force that original machinery produces above the medium, provides pretightening force by the internal pressure self of medium, and this structure can effectively reduce the size of the size, particularly fastening piece of former sealing configuration.Fastener bolt in the utility model only is the link of draw ring and flat cover, do not need to produce pretightening force, this just can improve the working life of bolt greatly, and simultaneously simple, the beautiful shape of sealing apparatus structure, easy accessibility have great application value.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model and beneficial effect thereof are described in further detail.
With reference to Fig. 1, a kind of high-pressure bottle self sealing structure comprises high pressure-volume Device 5On manhole or access opening, on the outside end face of described manhole or access opening draw ring 2 is set, the internal end surface place of this manhole or access opening arranges flat cover 6, described ring 2 and the flat cover of pining down 6Connect by bolt 1, make draw ring 2 tractions live flat cover 6And make flat cover 6Sealing manhole or access opening; Described ring 2 and the flat cover of pining down 6With described manhole or access opening contacting point be equipped with sealing gasket 3, 4, described flat cover 6And high-pressure bottle 5Be connected with the activity controlling device between the inwall, this activity traction gear is used for the motion of traction flat cover, realizes selfsealings.
Described activity controlling device comprises first, second connecting rod 9, 11, both are by first pin 10Hinged, described flat cover 6And high-pressure bottle 5Be welded with hanger on the inwall 7And otic placode 13, first, second connecting rod 9, 11Two ends after hinged is respectively by second pin 8With the 3rd pin 12And hanger 7, otic placode 13Hinged.
During operation, flat cover 6Be subjected to medium thrust, with sealing gasket 4Be pressed on the internal end surface place of manhole or access opening, realize selfsealings, equipment pressure is more high, and sealing effect is more good.
