Abstract
The utility model relates to a metal sealing ring, which comprises a circular ring-shaped stainless steel sheet with a circular arc structure punched on the inner side. The utility model is characterized in that a circular V-shaped slot corresponding to the circular arc structure is arranged on the stainless steel sheet near the circular arc structure. Because the circular V-shaped slot is added on the basis of the existing metal sealing ring, the strength of the sealing ring is increased on one hand, and on the other hand, the elasticity of the sealing ring is increased in the transverse direction on the basis of retaining the primary characteristics of the existing metal sealing ring. So the utility model results in the further development of the application of butterfly valves under the condition of high pressure.
Description
The utility model belongs to the mechanical sealing technology field, specifically a kind of particularly metal o-ring of butterfly valve of valve that is used for.
Butterfly valve now widely is applied to industry and civilian every field with its characteristics such as simple in structure, in light weight, easy to operate.In order to be applicable to various different operating environment, butterfly valve is developed into gradually and also is applicable to high temperature, high pressure by original low temperature, the low pressure of being only applicable to now, so its hermetic unit also changes present eyelet into by original seal with elastometic washer and seals firmly.At present, employed metal hard-sealing mainly is to rely on the metal spring circle to come instead of rubber as sealing seat on butterfly valve, therefore the key position of sealing is exactly a spring ring, and the structure of spring ring will directly influence the pressure of valve, the butterfly valve metal o-ring of selling on the market is by a ring stainless steel metal spring sheet, inboard punching press at this spring sheet has a ring-type arcuate structure, valve plate and spring ring produce the tight power of giving during use, make spring ring produce distortion, thereby realize sealing, though this structural type produces sealing force, and is stressed limited, be that employed seal ring can only reach pressure about 16 kilograms more than 200 millimeters as the valve diameter.
The purpose of this utility model provides and a kind ofly increases groove structure so that increase the novel metal seal ring of seal ring sealing effect.
The purpose of this utility model is achieved in that it comprises that its inboard punching press has the ring stainless steel metal sheet of a ring-type arcuate structure, it is characterized in that stainless steel metal sheet near the ring-type arcuate structure be provided with one with the corresponding ring-type V-shaped groove of ring-type arcuate structure.The usage of this metal o-ring is identical with existing seal ring.
The utility model is owing to increased the ring-type V-shaped groove on the basis of existing metal o-ring, therefore that is to say the intensity that on the basis that keeps primary characteristic, has increased seal ring on the one hand, increased the elasticity of seal ring on the other hand in the horizontal, can be by the pressure about 16 kilograms that reached originally, be increased to 25 kilograms pressure or bigger, make the application of butterfly valve under condition of high voltage stride forward a step again.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 is a form structure schematic representation of the present utility model
Fig. 2 be Fig. 1 partly cut open schematic representation
By shown in Figure 1, it comprises that its inboard punching press has the ring stainless steel metal sheet 1 of a ring-type arcuate structure 2, near on the stainless steel metal sheet 1 of ring-type arcuate structure oppositely punching press have one with the corresponding ring-type V-shaped groove 3 of ring-type arcuate structure, the opening direction through facts have proved ring-type V-shaped groove 3 is opposite with the opening direction of ring-type arcuate structure 2.The usage of this metal o-ring is identical with existing seal ring.
Claims (2)
1, a kind of novel metal seal ring, it comprises that its inboard punching press has the ring stainless steel metal sheet of a ring-type arcuate structure, it is characterized in that stainless steel metal sheet near the ring-type arcuate structure be provided with one with the corresponding ring-type V-shaped groove of ring-type arcuate structure.
2, metal o-ring according to claim 1 is characterized in that the opening direction of ring-type V-shaped groove is opposite with the opening direction of ring-type arcuate structure.
