Description
Technical field
The utility model relates to arrive Compressor Technology field, specifically a kind of piston compressor air-breathing that is applied to disappears
The sealing structure of sound device.
Background technique
Compressor is the heart of refrigeration system, and in process of refrigerastion, it, which constantly carries out compressing → condensation →, expands → steam
Send out the circulation of (heat absorption).Currently, the preferable plastics air suction silencer of heat-insulating property is widely used in the compressor of domestic refrigerator, sucking
The refrigerant of low-temp low-pressure, into refrigeration system.The leakproofness quality of air suction silencer air entry will affect the refrigeration of compressor
Therefore efficiency improves the sealing performance of air suction silencer air entry, guarantees the thermal-insulation function of air suction silencer, avoid sucking week
The refrigerant for enclosing high temperature and pressure is particularly important.Fig. 1, Fig. 2 and it is shown in Fig. 3 be a kind of currently used suction seal structure, it is close
Packing 5 is equipped with suction hole 7, and valve plate 6 is equipped with suction hole 8 and sealing counterbore 11, and the seal boss 11 on air suction silencer 1 is worn
It is locked in the sealing counterbore 11 on valve plate 6 after crossing the suction hole 7 of gasket 5.The sealing flange face 9 of air suction silencer 1 and close
Packing 5 forms first of sealing by compressing, and the sealing counterbore 11 on the seal boss 10 and valve plate 6 of air suction silencer 1 passes through
Cooperatively form second sealing.It is using the shortcomings that suction seal structure: due to the air-breathing hole end surface of air suction silencer, sealing
The plane precision of the sealing counterbore of boss and valve plate has many influence factors in machining process, there may come a time when to be not achieved and sets
Meter requires, and causes the air entry leakproofness of air suction silencer impacted, the refrigerant of high ambient temperatures high pressure is easily sucked, to reduce
The refrigerating efficiency of complete machine.
Summary of the invention
The technical problem to be solved by the utility model is to propose that one kind can simply and effectively enhance air suction silencer
Sealing performance guarantees the thermal-insulation function of air suction silencer, improves the gasket seal of the piston compressor of compression mechanism cold efficiency
Structure.
In order to solve the above technical problems, a kind of bead seal arrangement of piston compressor of the utility model includes that air-breathing disappears
Sound device, cylinder head, gasket and valve plate, the air suction silencer are equipped with suction hole and seal boss, set on the gasket
There is suction hole, the valve plate is equipped with suction hole and seals counterbore, and the set suction hole is less than described on the gasket
The Outside Dimensions of the set seal boss on air suction silencer, the seal boss is by the suction hole of the gasket
Marginal portion be pressed on it is described sealing counterbore side wall on.
A kind of bead seal arrangement of above-mentioned piston compressor is additionally provided with sealing flange face on the air suction silencer,
Sealing flange face on the air suction silencer is pressed together with the gasket.
A kind of bead seal arrangement of above-mentioned piston compressor, the assembly side of the seal boss and the sealing counterbore
Formula is gap, transition or interference fit.
The fit shapes of a kind of bead seal arrangement of above-mentioned piston compressor, the seal boss and sealing counterbore can
Using circular hole, square hole, elliptical aperture or irregular shape.
For the utility model due to using above-mentioned technical pattern, the sealing flange face of air suction silencer and gasket pass through pressure
Tight to form first of sealing, the seal boss side of air suction silencer and gasket pass through the sealing counterbore side on extruding and valve plate
Face forms second sealing.It is using the ductility of gasket seal in the seal boss side of air suction silencer and the sealing of valve plate
Increase between counterbore side wall and seal together, to simply and effectively enhance the sealing performance of air suction silencer, greatly reduces
The probability of air-breathing sealing joint failure, makes the sealing performance of air-breathing interface be significantly improved, ensure that air suction silencer
Thermal-insulation function effectively improves the refrigerating efficiency of compressor.Meanwhile using the sealing structure both without increasing cost, and
It is easy to operate, it is suitble to produce in enormous quantities and uses.

Specific embodiment
As shown in figure 4, a kind of bead seal arrangement of piston compressor of the utility model includes air suction silencer 1, consolidates
Clamp 2, cylinder head 3, gasket 5 and valve plate 6.Air suction silencer 1 is equipped with suction hole 4, and gasket 5 is equipped with suction hole 7, valve
Plate 6 is equipped with suction hole 8, and air suction silencer 1, gasket 5 and the installation of valve plate 6 are on the head 3.
As shown in figure 5, being additionally provided with sealing flange face 9 and seal boss 10 on air suction silencer 1, it is additionally provided on valve plate 6 close
Counterbore 11 is sealed, the suction hole 7 on gasket 5 is less than the Outside Dimensions of seal boss 10.Sealing flange face 9 and gasket 5 compress
Together, after seal boss 10 is pressed on the gasket 5 at 7 edge of suction hole, the sealing that part gasket 5 is pressed into valve plate 6 is sunk
The side in hole 11.Sealing flange face 9 and gasket 5 on air suction silencer 1 form first of sealing, air-breathing noise reduction by compressing
The side that seal boss 10 on device 1 passes through the surrounding end surfaces of suction hole 7 on extruding gasket 5 and the sealing counterbore 11 of valve plate 6
Close contact forms second sealing, the suction hole 7 of seal boss 10, gasket 5 on air suction silencer 1 and valve plate 6 it is close
Sealing counterbore 11 can be using diversified forms such as circular hole, square hole, elliptical aperture or other irregular shapes.Seal boss 10 and sealing are heavy
The assembly method in hole 11 can be gap, transition or interference fit.
