Abstract
The invention relates to a sealing structure, in particular to a quick sealing module of an anaerobe sample collecting device, which solves the defects of unreliable sealing, complicated structure and the like existing in an existing sealing structure and aims at the sealing of a box type sealing device under a special using environment. The quick sealing module of the anaerobe sample collecting device comprises an outer shell, wherein the inner side surface of the outer shell is provided with a Y-shaped sealing groove, the Y-shaped sealing groove is internally provided with a ladder-shaped sealing block, and an upper sealing cover body 1 is embedded in the outer shell and is clamped with the ladder-shaped sealing block. According to the quick sealing module of the anaerobe sample collecting device, provided by the invention, the sealing effect of a sealing device in microbial culture can be increased, the sealing structure can be simplified, and the sealing structure can be generally used for meeting requirements on box type sealing in various shapes.
Description
Technical field
Patent of the present invention relates to a kind of sealing configuration, is specially a kind of anaerobe sample collecting apparatus quick-sealing module.
Background technique
At present, the normal seal form adopted of pressurized container according to sealing means divide have several as follows:
Forced seal has: plain cushion sealing, Cachaly seal and octangonal ring sealing;
Semi-automatic seal has: seal with double-cone;
Self-tightening sealing has: wedge-type seal, wedge piece combination seal (claiming again wood closure), the sealing of hollow metal O shape ring, the sealing of C shape ring, the sealing of B shape ring, delta gasket closure, octangonal ring sealing and plain cushion self-tightening sealing.
The various seal arrangements that exist on market are by pressure, half self-tightening and self-tightening mode, under the mutual squeezing action of flange contact facings, by sealing gasket deformation, by the method for zone to be sealed realization.For the sealing of chamber installation, run into following several problems in above encapsulating method using process:
When one side has than shallow grooves, and another side extremely easily causes seal ring to be decided to be difficult problem while being plane.The reliability of the sealing of equipment under rugged environment and the convenience of operation have been reduced.
The problems such as there are complex structure in delta seal pad and combination seal pad etc., to box sealing, exist design difficulty large, use complexity high, and simple operation is poor.
Summary of the invention
The present invention, in order to solve the deficiencies such as unreliable and complex structure that exist in existing sealing configuration, for the sealing of Special use environment box type seal arrangement, provides a kind of anaerobe sample collecting apparatus quick-sealing module.
Technological scheme of the present invention is, a kind of anaerobe sample collecting apparatus quick-sealing module, comprise frame, at the frame inner side surface, is provided with the Y shape seal groove, trapezoidal sealing block is installed in the Y shape seal groove, and top cover labyrinth body 1 embeds frame and trapezoidal sealing block pressing.
With existing sealing means, compare, the present invention is right angle Y shape groove structure in the lower part-structure edge designs of housing structure, with the use ladder-shaped sealing ring, by changing the shape of flanged surface and seal ring, change the stress form in the seal ring mechanism, fully increase seal ring deformation simultaneously, guiding it to change the deformation direction, thereby improve sealing, realizing the better spacing effect that simultaneously improves sealability.Compare with sealing configuration with typical group, cancelled and pind down bolt, nut and pin down ring structure, make simple in structure, easy to operate, cost and the larger advantage of sealing force.There is Applicable scope widely on this patent size and pressure, be not subject to the restriction of seal ring size.The using scope (diameter D=600～800mm, temperature t<350 ℃, pressure p >=30MPa) that is relatively typical wood closure circle is wanted extensively.Right angle " Y " shape groove, large than conventional " O " type groove face frictional force, thus realize position-limiting action preferably, facilitated installation.Anaerobe sample collecting apparatus quick-sealing module of the present invention, the water-tight equipment in cultivating microorganism improves sealing effect, simplifies sealing configuration.The sealing structure can be generally for the box sealing demand of various shapes.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The A-A that Fig. 2 is Fig. 1 is to sectional view.
Embodiment
As schematically shown in Figure 1, 2, a kind of anaerobe sample collecting apparatus quick-sealing module, comprise frame 3, at frame 3 inner side surfaces, is provided with the Y shape seal groove, trapezoidal sealing block 2 is installed in the Y shape seal groove, and top cover labyrinth body 1 embeds frame and trapezoidal sealing block 2 pressings.
Be provided with Y shape waist bar 4 at frame 3 inner side surfaces, described Y shape seal groove is connected and composed by Y shape waist bar 4 and frame.
This invention is applied to flange arrangement, by design, only needs a flanged surface to get final product with right angle " Y " type groove, and another side can be plane, can be also special surface, reduces greatly production difficulty, and reduces processing technology.Wherein the right angle of a flanged surface " Y " type groove can, by conventional milling machine processing, also can coordinate the waist bar to weld or spot welding processing by dull and stereotyped with one.This groove only need to play position-limiting action, and seal process is the deformation realization by ladder-shaped sealing ring.Difficulty of processing and processing request to flanged surface have so just been greatly reduced.
The seal ring of this technological method has adopted the trapezoidal sealing gasket with good deformability ability and resilience, in the using process of sealing pad, under two Mechanical Contact faces and side acting in conjunction, make the seal ring pressure form triaxial pressure, realizing that sealing function simultaneously, can also realize good limit function, and between both ends of the surface, pressure is larger, the advantage embodiment of position-limiting action is stronger, sealing effect is also better.
This sealing configuration is made simple, and low to the flanged surface processing request, simple in structure, bolt pretightening is little, can be widely used in storage and cask and the box seal element of the industry fluids such as oil, chemical industry, light industry, food.
