Abstract
The utility model discloses a self-adaptive high-reliability honeycomb structure metal sealing piece, which comprises the following components: the stainless steel ring is provided with an annular groove on the peripheral side wall, and a plurality of honeycomb holes are uniformly distributed on the bottom surface of the annular groove. The sealing piece is made of stainless steel, has high strength, is not easy to cause the problem of extrusion damage, ensures tightness, and is provided with the annular groove and the honeycomb holes, so that the rebound resilience of the stainless steel ring is good, and the sealing piece can be more attached to the element under the condition of less compression during extrusion, thereby achieving better sealing effect and ensuring that the sealing surface is kept in close contact with the pressure, the temperature and the vibration limit.
Description
Technical Field
The utility model relates to the technical field of sealing elements, in particular to a self-adaptive high-reliability honeycomb structure metal sealing element.
Background
Currently, the connections between multiple metal fluidic components 100 (including, but not limited to, diaphragm valves, pressure regulating valves, pressure reducing valves, etc. fluid control components) are typically connected by a connection block 200 to enable the formation of a smooth gas channel. While the sealing ring 300 is often disposed on the corresponding channel hole between the metal fluidic component 100 and the connection block 200 to ensure the tightness of the corresponding channel hole (see fig. 1-2), the sealing ring 300 generally uses a plastic gasket (PCTFE material), a rubber gasket, a metal gasket, and an NI gasket. However, when the sealing ring made of plastic gasket, rubber or silica gel is used, the problem of extrusion damage caused by large extrusion force exists, and the sealing failure is caused; and the rebound resilience of the existing metal gasket and the NI gasket is poor, and the sealing performance in practical application is low.
Therefore, it is a need for a person skilled in the art to provide an adaptive high reliability honeycomb metal seal that has good resilience, high strength, less damage, and good sealing.
Disclosure of Invention
In view of this, the present utility model provides a self-adaptive high reliability honeycomb structural metal seal having good resiliency, high strength, less damage, and good sealing properties.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
an adaptive high reliability honeycomb metal seal comprising: the stainless steel ring is provided with annular grooves on the peripheral side wall, and a plurality of honeycomb holes are uniformly distributed on the bottom surface of each annular groove.
Compared with the prior art, the self-adaptive high-reliability honeycomb structure metal sealing piece is made of stainless steel, has high strength, is not easy to damage due to extrusion, ensures tightness, is good in rebound resilience of the stainless steel ring and honeycomb holes, can be attached to elements under fewer compression conditions during extrusion, achieves a better sealing effect, and ensures that a sealing surface is kept in close contact with pressure, temperature and vibration limit.
Further, the surface roughness of the stainless steel ring is smaller than 0.1. Thus, the surface of the stainless steel ring is smooth, and special gas or toxic liquid or corrosive liquid can be prevented from being easily attached to the stainless steel ring due to the fact that the inner ring of the stainless steel ring is rough.
Further, the radius of the honeycomb holes is 3.5mm. The depth h of the honeycomb holes is 10.3mm.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 3-5, embodiments of the present utility model disclose an adaptive high reliability honeycomb metal seal comprising: the stainless steel ring 1, offer the ring channel 11 on the periphery lateral wall of stainless steel ring 1, equipartition has offered a plurality of honeycomb holes 111 on the groove bottom surface of ring channel 11.
The stainless steel ring is manufactured by secondary smelting of stainless steel, so that nonmetallic inclusion in the material is reduced, crystal grains are uniform, element proportion is better, corrosion resistance and strength are improved, and the service life of the sealing ring is prolonged. The honeycomb design is adopted in the stainless steel ring outside, can make the sealing washer more laminate the component under the compression condition less, reaches better sealed effect, and the honeycomb design in outside has also guaranteed certain stability, makes the sealing washer when high pressure differential, little clearance seal, still can guarantee the inseparable laminating of component to reduce leakage loss, improve the leakproofness.
Wherein, the surface roughness of the stainless steel ring 1 is less than 0.1. The radius of the honeycomb holes 111 is 3.5mm. The depth h of the honeycomb holes 111 was 10.3mm. The spacing between two adjacent cells 111 is 7.49mm. The diameters of the inner ring and the outer ring of the stainless steel ring 1 are respectively 45.8mm and 71.5mm. According to the test, the current sealing ring has the best size, and can meet the requirement of no leakage.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant points refer to the description of the method section.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present utility model is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
