Description
Technical field
This utility model relates to a kind of sealing rubber pad, a kind of rubber gasket for vacuum equipment.
Background technology
At chemical fields such as food, pharmacy, titanium sponges, vacuum response stove is widely used, and vacuum response stove is by close
Envelope rubber blanket realizes the isolation at vacuum position and external environment.Chinese utility model patent CN
202884015U discloses a kind of special solid seal gasket of vacuum response stove, extends the use longevity of rubber blanket
Life, improves sealing effectiveness.But, this rubber blanket in use deformation quantity is relatively big, in order to ensure sealing effectiveness rubber
The thickness of pad have to be significantly greater than the groove diameter of installation site, causes rubber blanket to be not easy to install, sealing gasket easily occurs
The problem that displacement comes off.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of rubber gasket for vacuum equipment, it is possible to solve
The deficiencies in the prior art, reduce sealing gasket deformation quantity in use, it is simple to install and use.
For solving above-mentioned technical problem, technical solution adopted in the utility model is as follows.
A kind of rubber gasket for vacuum equipment, including annular body, is provided with cavity in described annular body, empty
The bottom in chamber is provided with the first elastic sheet metal, and it is convex that the top of the first elastic sheet metal is provided with several arcs being parallel to each other
Rise, the first elastic sheet metal be provided above the second elastic sheet metal, between the first elastic sheet metal and the second elastic sheet metal
Gap coordinates, and the bottom of annular body is provided with the first rubber blanket, and the lateral wall of annular body is provided with the second rubber blanket, the second rubber
Vertical dimension between rubber cushion and the second elastic sheet metal is 1:7 with the ratio of the thickness of annular body itself.
As preferably, the medial wall of described annular body is internally provided with air bag.
As preferably, the bottom of described second rubber blanket is provided with several rubber shanks, and rubber shank includes and second
The root that rubber blanket connects, root is connected by torsional part disk, and the outside of disk is provided with toothed region.
What employing technique scheme was brought has the beneficial effects that: this utility model is by arranging in rubber gasket
Two elastic sheet metals, can be effectively improved rubber gasket supportive in the case of large deformation, thus it is close to reduce rubber
Packing total deformation quantity in use.First rubber blanket is used for improving the supporting degree of rubber gasket vertical direction, and second
Rubber blanket is used for improving the sealing of equipment faying face.Owing to vacuum response furnace interior reaction temperature is high, in annular body
Interior arranges air bag, it is possible to use the effect of expanding with heat and contract with cold of gas is effectively improved the sealing effectiveness of high temperature position.Rubber pin
Body is when equipment faying face mutually compresses, and torsional part deforms upon, and makes disk be mutually inserted fixing, thus improves equipment further
The sealing effectiveness of faying face.
