Abstract
The present utility model relates to a combined wedge-shaped sealing ring, the main characteristic of which is that a concentric annular groove is set on the circumference of the annular sealing body, on the said annular groove a annular limited sealing body is set. The present utility model is with advantages of simple structure, low manufacturing cost and long service life. Said combined wedge-shaped sealing ring has the remarkable limited function during the course of using it and prevents the sealing ring from pressing and rupturing, since the annular limited sealing body made of metal or plastics is inserted into the circumference of the annular sealing body, and it has the advantages of strong bearing capacity, better sealing performance. Said combined wedge-shaped sealing ring is not visible, out of touch with the outer environment, and has good anti-retrogradation effect.
Description
One, technical field
The utility model relates to a kind of seal ring, and specifically a kind of combination wedge type seal ring belongs to mechanically a kind of air locking.
Two, background technique
In the mechanical assembly technique field, in order to make liquid or gas smooth smoothly in machinery, it is attached usually to accompany different seal ring pad between mechanical fitting and mechanical fitting, just can reach not leakage liquid or gas, and the internal cavity sealing effect just can reach designing requirement like this.For example when transformer, mutual inductor, high-voltage switch gear, High-Voltage Electrical Appliances, gas pipeline and motor etc. are equipped with the assembling of liquid or gas, all need to seal butt joint, prevent that the joint poor sealing from causing leakage gas leakage with seal ring.Existing seal ring adopts homogenous material mostly, as elastic seal rings such as rubber seal and cork-rubbers, and easy deformation after this sealing material in use is squeezed, the pressure that bears is very limited.When accessory is connected with accessory the extruding degree of seal ring is not easy to grasp, does not have limit function so that usually be air locking connect not in place cause poorly sealed, the excessive seal ring that damages by pressure of perhaps exerting oneself.On the other hand, outside the mechanical electric apparatus equipment of some band seal ring was exposed to throughout the year, seal ring also was exposed to the field, and wind rain shines, and is easy to generate deterioration phenomenon.
Three, model utility content
The purpose of this utility model does not have limit function in order to solve existing seal ring exactly, in use is easy to generate deterioration phenomenon, thereby proposes a kind of new technological scheme.
The technological scheme that the designing technique defective of its existence of solving the utility model is adopted is: a kind of combination wedge type seal ring, it is to be made of annular sealing member, be provided with the annular concentric groove on annular sealing member circumference side, being provided with the cross section in annular groove is the annular stop seal of rectangle.
The edge of the circumference of annular sealing member be shaped as arc, described annular stop seal is metal or plastic materials.
The advantage that the utility model had is: simple in structure, easy to use, cheap for manufacturing cost, and long service life.Because wedging is provided with hard material annular stop seals such as metal or plastics on annular sealing member outer side surface circumference, the combination wedge type seal ring that is constituted in use has significant limit function, also can prevent seal ring extrusion-deformation and break, ability to bear strengthens greatly, and sealing effect is better.On the other hand, the utility model has been eliminated seal ring and has been exposed, and has good anti-aging effect.
Four, description of drawings
Accompanying drawing 1 is a kind of example structure schematic representation of the utility model;
Accompanying drawing 2 is that the A-A of the utility model accompanying drawing 1 is to the sectional structure schematic representation.
Five, embodiment
Do an annular sealing member (1) with cork-rubber or the high-elastic gonosome of rubber-like, on its periphery face, be provided with the annular concentric groove, in annular groove, be provided with the annular stop seal (2) that metal that the cross section is a rectangle or high hardness plastic materials are made.The circumferential edges shaped design of annular sealing member (1) is that the arc using effect is better.
Make when of the present invention, annular stop seal (2) and (a 1) hot pressing of annular sealing member can be formed, can reduce its manufacture cost greatly like this.
Claims (2)
1, a kind of combination wedge type seal ring, it is to be made of annular sealing member, it is characterized in that: be provided with the annular concentric groove on annular sealing member (1) circumference side, being provided with the cross section in annular groove is the annular stop seal (2) of rectangle.
2, a kind of combination wedge type seal ring according to claim 1 is characterized in that: the edge of the circumference of annular sealing member (1) be shaped as arc, described annular stop seal (2) is metal or plastic materials.
