By using technique scheme, after gas flows through air vent, gas occurs to overflow under the effect of breach and dissipates, gas
The air pressure after dissipating that overflows diminishes, and the gas of air vent fresh air inlet one end is pressed into the side of sealing gasket air-out, accelerates drafting efficiency, makes
Compressor efficiency is high.Owing to gas is rotated generation by impeller, gas rotating enters sealing gasket, and breach is positioned at the circular hole center of circle and installation
The straight line side that the center of circle, hole is formed, makes air-flow flow along breach, and the resistance that when dissipating, gas is subject to that overflows is little, and making to overflow, it is good to dissipate effect
Good.Air vent is circumferentially with several around the installing hole center of circle along installing hole, and after passing the gas through sealing gasket, flowing is uniformly.
Of the present utility model it is further arranged to: described breach is circular arc.
By using technique scheme, circular arc easy making process, only need to punch.Circular arc is without flanging, gas simultaneously
When body flows in breach, breach will not be by concentrated stress, and sealing gasket main body is difficult to cracking situation in indentation, there.
Of the present utility model it is further arranged to: the shaft section of described sealing gasket main body is that circular arc is arranged.
By using technique scheme, form a NOL ring.When sealing gasket is installed, two things sealed along with sealing gasket
Body close, i.e. more and more less with the spacing between two articles, the cross section radian of sealing gasket bulk deformation, i.e. sealing gasket main body more comes
The biggest, sealing gasket main body is more and more flat, makes between sealing gasket main body and two articles all in abutting closely, prevents gas from leaking.
Simultaneously during sealing gasket main body flattens, the gas under sealing gasket main body radian is extruded away, sealing gasket main body following table
Face air pressure diminishes, and makes sealing gasket main body fit more closely with object.
Of the present utility model be further arranged to: described sealing gasket body outer wall circumferentially arranged with chimb, described chimb position
Bottom sealing gasket body outer wall.
By using technique scheme, sealing gasket main body and the contact surface of object when increasing malcompression sealing gasket main body
Long-pending, when making compression sealing gasket main body, sealing gasket Soil stability is placed on body surface, facilitates the installation of sealing gasket.Close compressing
During packing main body, sealing gasket main body has counteracting force to object, and the counteracting force making object be subject to is evenly distributed, and object will not be subject to
Concentrated stress, prevents from damaging body surface.
Of the present utility model it is further arranged to: on described sealing gasket, have some lightening holes.
By using technique scheme, reduce the weight of sealing gasket, decrease making material, saved cost.
Of the present utility model it is further arranged to: described installing hole sidewall radially has locating slot.
By using technique scheme, use locating slot to position, make sealing gasket accurately be arranged on object, simultaneously
Prevent sealing gasket skew during fit sealing pad main body.
Of the present utility model be further arranged to: described locating slot circumferentially arranged with several, described locating slot and loss of weight
Hole communicates.
By using technique scheme, when sealing gasket main body is given a shock, sealing gasket body interior can produce deformation,
Reduce shaking force, serve the effect of buffering.
This utility model has the advantage that acceleration gas flowing, improves compressor efficiency, the most easy to crack, it is simple to location
Install, good sealing effect, low cost, play the effect of buffering.

Detailed description of the invention
Referring to the drawings this utility model is described further.
As it is shown in figure 1, a kind of sealing gasket for compressor, including sealing gasket main body 1, the plate-shaped list of sealing gasket main body 1
Rotating fields.Simple in construction, convenient processing and manufacture, low cost of manufacture, the material that single layer structure needs is few, cost-effective.Sealing gasket
Main body is fabricated by by SPCC, vulcanizes after sealing gasket main body 1 molding in the curing cage of 220 ° of C, to strengthen sealing gasket master
The structural strength of body 1.
The rounded shape of sealing gasket main body 1, the i.e. outline in the cross section of sealing gasket main body 1 are circular.As in figure 2 it is shown, in order to
The sealing effectiveness making sealing gasket is good, and the sectional area of sealing gasket main body 1 is that circular arc is arranged.In order to install when preventing from installing sealing gasket
The contact surface of sealing gasket is owing to being deformed by concentrated stress, as shown in Figures 2 and 3, sealing gasket main body 1 outer wall circumferentially arranged with
Chimb 2, chimb 2 is positioned at bottom sealing gasket main body 1 outer wall.
As it is shown in figure 1, sealing gasket main body 1 center has installing hole 3, installing hole 3 is used for installing axle.In sealing gasket main body 1
Offering air vent 4, air vent 4 includes that sidewall has the circular hole of circular arc cutaway 5, and breach 5 is positioned at the circular hole center of circle and installing hole 3
The straight line side that the center of circle is formed, air vent 4 is circumferentially with several around installing hole 3 center of circle along installing hole 3.If having on sealing gasket
Dry lightening hole 6, the shape of lightening hole 6 is determined by force analysis.I.e. remove close in the case of the structural strength ensureing sealing gasket
Material instrument unnecessary on packing carries out loss of weight and cost-effective.Installing hole 3 sidewall radially has locating slot 7.Locating slot 7 is along week
To being provided with several, locating slot 7 communicates with lightening hole 6, defines activity template 8 in sealing gasket main body 1.
Fixing hole 9 and oil through 10 is also had in sealing gasket main body 1, in order to make to connect between sealed object fastening, fixing
Hole 9 is circumferentially with three along sealing gasket main body 1.Oil through 10, between two air vents 4, does not interferes with while logical oil
The circulation of gas, it is ensured that the circulation of gas, and then ensure that the work efficiency of compressor.
If needing sealed object one and object two.When this sealing gasket is installed, by locating slot 7, sealing gasket main body 1 is accurately fixed
Position is placed on object one, places object two, by bolt through fixing hole 9, tight a bolt in sealing gasket main body 1.Sealing gasket
Main body 1 is driven plain, and during flattening, the gas under sealing gasket main body 1 radian is extruded away, sealing gasket main body 1 following table
Face air pressure diminishes, and makes sealing gasket main body 1 fit more closely with object, serves good sealing function.It is subject at sealing gasket
During vibrations, activity template 8 is movable, reduces the vibrations that sealing gasket main body 1 is subject to, serves the effect of bumper and absorbing shock.
Specifically add man-hour, use mould to carry out the production and processing of sealing gasket, it is achieved to produce in enormous quantities, reduce and be manufactured into
This.In compressor operation, the temperature within compressor is higher, therefore, and the resistance to pressure of sealing gasket and heat resistant requirements
Higher.Sealing gasket main body 1 uses metal-rubber composite, and the performance of this material is good, uses extensively, and low cost is processed into
Sealing gasket be difficult to aging deformation, resistance to pressure and thermostability are high, and service life is long, and long-time use after still have good
Sealing effectiveness.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
