Abstract

The utility model discloses a high-pressure vessel end ring surface self-adaptation compensation strengthening hydraulic seal device which comprises a seal cover. The seal cover comprises a plug provided with an arch cavity on the lower portion. A seal punch sleeve is mounted outside the plug. An annular wedge groove is reserved on the outer wall at the lower end of the seal punch sleeve. A wedge seal ring is mounted in the wedge groove in a matched manner. A rigid pressing ring for pressing the wedge ring is disposed at the wedge groove of the seal punch sleeve. The hydraulic seal device aims to meet the end ring surface dynamic and static hydraulic seal requirements of large and medium high-pressure or ultrahigh-pressure vessels, on the premise of guaranteeing airtightness and by optimizing seal part structures, pretightening force of seal parts can be adjusted dynamically by means of self-adaptation according to pressure variations in the vessels. When vessel ends are assembled, assembling difficulty can be lowered evidently due to the fact that certain initial assembling gaps are allowed to exist. Seal reliability of seal parts is achieved while assembling and disassembling difficulty of pretightening parts is solved.

Description

The compensation of high-pressure bottle end ring surface self-adaption strengthens hydraulic seal device
Technical field
Dynamic, the self adaptive-compensating of static liquid means of press seals that the utility model relates to the container end portion anchor ring of a kind of large scale, ultrahigh pressure strengthen technical field, relate in particular to a kind of high-pressure bottle end ring surface self-adaption compensation and strengthen hydraulic seal device.
Background technique
The seal arrangement of high-pressure bottle or ultrahigh pressure vessel is most important sealed member in container assembling and the operation, sealed member based on high pressure or ultrahigh pressure vessel end should guarantee its fitting tight performance, again must be in the initial loading timing, guarantee that between container barrel and the end sealed member be Spielpassung, so that assembling neatly.It is a pair of inevitable contradiction aspect two that the seal arrangement of high-pressure bottle or ultrahigh pressure vessel seals this in initial assembling and operation.
According to the use condition of reality, during assembling, can only overcome initial sealing frictional force by the deadweight of sealing lid substantially, to finish assembling and the inner emptying that is closed air.Generally speaking, the sealing lid is difficult to the disposable rigging position that drops to automatically, often needs to adopt some external accessories or measure, could finally finish the assembling of sealed member.And, after assembling is finished, guarantee the normal operations involving high pressure of container, container must fully reach sealing state, but because container needs the Spielpassung between parts when assembling, so after the assembling, often exist the space between sealed member and the high-pressure bottle, the measure that remedies (as filled etc.) must be taked, otherwise its sealing effect can be influenced.But because filler is operated comparatively trouble, and sealing effect is also undesirable, and this is just having a strong impact on the working performance of high-pressure bottle or ultrahigh pressure vessel.
The model utility content
Deficiency at the prior art existence, the purpose of this utility model is to provide a kind of high-pressure bottle end ring surface self-adaption compensation to strengthen hydraulic seal device, strengthen know-why and optimized the structure that seals lid by self adaptive-compensating, can solve the problems of the technologies described above effectively.
The purpose of this utility model is achieved through the following technical solutions:
A kind of high-pressure bottle end ring surface self-adaption compensation strengthens hydraulic seal device, comprise the sealing lid, the sealing lid mainly is made of cock body, the bottom of described cock body has the arch chamber, the outside of cock body is equipped with the sealing punch cover, have the wedge slot of annular on the outer wall of sealing punch cover lower end, coupling is equipped with wedge shape sealing ring in this wedge slot, is provided with the rigidity pressure ring that holds wedge shape sealing ring at the wedge slot place of sealing punch cover.
In order to realize sealing effect of the present utility model better, between described rigidity pressure ring and the wedge shape sealing ring seal joint is installed.
In order to realize better sealing effect, between the end, lower end of described rigidity pressure ring and sealing punch cover rubber seal is installed, between described seal joint and the wedge shape sealing ring rubber seal is installed, the barrel of this rubber seal and high-pressure bottle closely acts on, rubber seal is owing to precompression produces pretightening force, during the period, this pretightening force can realize the seal action of container in the operation of high-pressure bottle low pressure.
Further technological scheme: the appearance wall depression of described sealing punch cover has some circular grooves, and rubber seal is installed in circular groove.
The utility model provides the shape and structure technological scheme in a kind of arch chamber: described arch chamber overall structure is ball collar shape or cylinder arch or step arch.
The utility model provides a kind of manufactured materials technological scheme of sealing punch cover: described sealing punch cover and wedge shape sealing ring form by the manufacturing of tin bronze material.
As a kind of optimized technical scheme of the present utility model be, described sealing lid also includes end cover, and described end cover is located at cock body away from an end end in arch chamber.
The utility model is compared than prior art, has the following advantages and beneficial effect:
(1) the utility model aims at dynamic, the static liquid means of press seals demand of annular end of large and medium-sized high pressure or ultrahigh pressure vessel, under the prerequisite that guarantees sealability, by the sealed member structure of optimizing, realization is along with the rising of container internal pressure, the seal arrangement local pressure expands, thereby self adaption is dynamically adjusted the pretightening force of sealed member.When container assembles, owing to allow certain initial fit up gap, the utility model can be guaranteed reliable sealability in the container ultrahigh pressure working state, simultaneously the excessive pretension defective of sealed member of current existence be can avoid effectively, thereby the reliability of sealed member sealing and a pair of contradiction difficult problem of component pretension state dismounting difficulty solved well.
(2) the utility model adopts wedge shape sealing ring to add the compound sealing structure of rubber seal, when assembling, adopts the Spielpassung of appropriateness between the cylindrical shell of wedge shape sealing ring and punching block sleeve containes, produces unnecessary clamping stagnation when having avoided cock body just to pack into.Guarantee in the sealing of the low pressure period precompression by rubber seal, because rubber seal is the rigidity soft material, has realized the seal action of low pressure period, and provide the initial pressure of punching block sleeve containes or other high-pressure bottle to provide.
(3) the utility model can improve the recycling rate of waterused of sealed member, effectively reduces cost.The utility model is also applicable to the axial motive sealing operating mode demand of container end portion cock body.
