Description
Technical field
The invention belongs to mechanical field Sealing Technology, relate to the partially sealed device under a kind of high temperature bump contact and encapsulating method.
Background technology
When fluid flows through two interconnective parts, owing to the gap of union piece contact position can produce leakage, usually need to seal in two union piece contact positions.Sealing between feature contacts place generally has following several ways: first: seal with O ring；Second: gasket seal；3rd: gluing seals.Mode one is applied relatively broad, and sealing effectiveness is also fine, but due to O many employings elastomeric material, at high temperature uses and easily aging and lost efficacy；Mode three easily makes glue incoming fluid flow through space when gluing, is only applicable to convection cell cleannes and requires low occasion；The structure of mode two is applicable to whole flange face is sealed, can also be used for hot environment, but to ensure to seal reliably, two planes of the feature contacts that is connected must have significantly high machining accuracy, when contact plane is bigger, namely bring difficulty to plane machining, also result in unnecessary waste, simultaneously when temperature is higher, fix the bolt of two parts because expansion can cause that the gap of two parts increases, the compressive stress of pad diminishes, and deformation diminishes, and affects sealing effectiveness.
Summary of the invention
Namely the purpose of the present invention thus produces, it is proposed to partially sealed device under a kind of high temperature bump contact and encapsulating method.
The present invention adopts following technical proposals to complete its invention task:
Partially sealed device under a kind of high temperature bump contact, described sealing device includes special-shaped pad and spring two parts；Described special-shaped pad is loop configuration, and the cross section of the described special-shaped pad of loop configuration is " U "-shaped, and " u "-shaped outward opening；Under described spring free state, two ends connect becomes a circle, is placed on the bottom of special-shaped pad " u "-shaped, is integrally forming with special-shaped pad；The cross section of described spring is circular；The bottom of the " u "-shaped of described special-shaped pad is the circular arc that the circular kiss with described spring is joined.
The method utilizing described partially sealed device that part is sealed, part I and the part II that need to connect have fluid flow path passage；The part I that need to connect and part II in conjunction with in plane, fluid flow path passageway perimeter, one cannelure of processing respectively, described part I in conjunction with plane, part II corresponding up and down in conjunction with the cannelure in plane, the degree of depth of described cannelure is less than the half of the " u "-shaped opening of special-shaped pad, the aperture of described cannelure is slightly larger than special-shaped pad external diameter, when part is sealed, after sealing device being installed in the cannelure of part I and part II, it is bolted part I and part II and compresses；The upper surface of special-shaped pad, lower surface pressurized rear spring are deformed, rely on spring recover tension force and part I in conjunction with plane, part II in conjunction with the coefficient pressure of plane, the upper surface of special-shaped pad, lower surface is made to produce deformation, fill the gap of part I and part II contact surface, it is achieved the sealing between part I and part II.
Partially sealed device under a kind of high temperature bump contact proposed by the invention and encapsulating method, compared with conventional sealing apparatus and method, have the following characteristics that 1, only part junction need to be carried out local polish, the local under part bump contact can be realized reliably seal, reduce the processing cost of union piece；2, only seal in fluid flow path channel circumference part, make there is enough pressure inside this special-shaped pad, it is ensured that the sealing of fluid；3, spring produces elastomeric radial after being subject to radial pressure, and the deformation of spring is relatively big, in high temperature environments, due to rebound effect, make special-shaped pad deformation keep being basically unchanged, and the stress between two end faces of special-shaped pad is essentially identical, thus ensureing to reliably seal.

In figure: 1, special-shaped pad, 2, spring, 3, upper surface, 4, lower surface, 5, part I in conjunction with plane, 6, part II in conjunction with plane, 7, part I, 8, part II.
Detailed description of the invention
In conjunction with the embodiment that accompanying drawing provides, the present invention is illustrated:
As it is shown in figure 1, the partially sealed device under a kind of high temperature bump contact, described sealing device includes special-shaped pad 1 and spring 2 two parts；Described special-shaped pad 1 is " U "-shaped by the rammed cross section of corrosion resistant plate, and the loop configuration of " u "-shaped outward opening；The cross section of described spring 2 is circular；Under spring 2 free state, two ends connect becomes a circle, is placed on the bottom of special-shaped pad " u "-shaped, is integrally forming with special-shaped pad 1；The bottom of the " u "-shaped of described special-shaped pad is the circular arc that the circular kiss with described spring is joined；
As shown in Figure 2, utilize the method that part is sealed by described partially sealed device, the specific embodiment of the invention is as follows: before installation, the part I that need to connect and part II in conjunction with in plane, fluid flow path passageway perimeter, one cannelure of polish respectively, described part I in conjunction with plane 5, part II corresponding up and down in conjunction with the cannelure in plane 6, the slotted eye degree of depth of cannelure is less than the half of special-shaped pad " u "-shaped opening, slotted eye aperture φ 2 is special-shaped pad internal diameter slightly larger than special-shaped pad external diameter φ 1, φ.When part is sealed, after being installed on by sealing device in the cannelure of part I 7 and part II 8, being bolted part I 7 and part II 8 and compress, the δ size in Fig. 2 is gradually reduced, and finally makes part I 7 and part II 8 fit (namely δ is 0).Owing to two union piece slot size sums are less than special-shaped pad " u "-shaped opening size, when δ is 0, part I compress special-shaped pad upper surface 3 and special-shaped pad lower surface 4 in conjunction with plane 6 in conjunction with plane 5 and part II, special-shaped pad 1 produces plastic deformation after bearing certain compressive stress, simultaneously special-shaped pad 1 again a part of Stress Transfer to spring 2, spring 2 also creates corresponding elastic deformation under the effect of external force, when external force reaches sufficiently large, when making special-shaped pad 1 produce to ensure to seal the reliable and plastic deformation of necessity, spring 2 also creates enough elastic deformations.So just ensure that special-shaped pad 1 has suitable initial plastic deformation, and when the compressive stress that machine longtime running or variations in temperature cause diminishes, and owing to the compressive stress of special-shaped pad 1 is had very big compensating action by the existence of spring 2, thus ensure that compressive stress is basically unchanged, finally ensure that reliable sealing effectiveness.
