Description
Technical field
The present invention relates to technical field of refrigeration compressors, it is specifically a kind of for reciprocating compressor, by refrigerant
The exhaust valve group of cylinder is discharged.
Background technology
The movement of compressor piston so that inner pressure of air cylinder changes, so as to cause the opening and closing of suction valve chip.
When piston is moved to tail cylinder, the pressure in cylinder is caused to be less than the pressure in compression case body, inlet valve is opened at this time,
Refrigerant in shell enters cylinder.When piston is moved to cylinder head, the pressure in cylinder can increase；When the pressure in cylinder
When power is more than the pressure in shell, inlet valve is closed；When the pressure in cylinder continues growing and is more than the pressure in discharge chamber,
Air bleeding valve is opened, and refrigerant enters discharge chamber.When piston motion to top dead-centre, exhaust terminates, and piston is again to tail cylinder at this time
Movement, a new cycle start.Like this, the pressure in reciprocating compressor cylinder constantly changes, so as to cause inlet valve and
The opening and closing of air bleeding valve.
In household compressor field, since refrigerating capacity is little, the arrangement of generally use one air entry and an exhaust outlet
Mode disclosure satisfy that requirement of the user to Performance And Reliability.And in the compression of commercial compressor field, especially High cooling power
Machine needs the area for increasing air entry and exhaust outlet, designer that would generally arrange multiple air entries and exhaust outlet on valve plate.
Due to the limitation in space, often increase the rigidity of suction valve chip and exhaust valve plate, but the power of some valve blocks can be lost in this way
Performance is learned, the working efficiency of compressor is reduced.In addition, big specification commercial compressor is since its refrigerating capacity is very big, the row of acting on
Fluid-load on air valve can be very big, needs to design solid reliable limiter to limit the lift of air bleeding valve, limit entire in this way
Position device has been also subjected to prodigious load.

In order to solve the above technical problems, a kind of exhaust valve group for reciprocating compressor of the invention includes valve plate, air bleeding valve
Piece, damping fin, limiter, cylinder head gasket and cylinder head, the exhaust valve plate, damping fin and limiter stack successively to be fixed on
On the valve plate, the exhaust valve plate is equipped with air bleeding valve, and the air bleeding valve is covered on exhaust outlet set on the valve plate；
The both sides of the limiter are respectively equipped with claw, and the claw is pressed respectively in set two grooves on the valve plate, institute
Cylinder-top gasket on piece is stated equipped with two horizontal stripes and is pressed on respectively on the claw of the limiter both sides, is set in the cylinder head
It is pressed on there are two platform and respectively on two horizontal stripes set by the cylinder-top gasket on piece.
A kind of above-mentioned exhaust valve group for reciprocating compressor, sets that there are two air bleeding valve, Mei Gesuo on the exhaust valve plate
It is symmetrical about center line to state air bleeding valve itself；It is set on the valve plate there are two the exhaust outlet, two air bleeding valves divide
It is not covered on two exhaust outlets.
A kind of above-mentioned exhaust valve group for reciprocating compressor, the head of the damping fin set that there are two reeds.
The head centre of a kind of above-mentioned exhaust valve group for reciprocating compressor, the limiter is equipped with stopper at two.
A kind of above-mentioned exhaust valve group for reciprocating compressor, the claw set by the limiter both sides are pressed on the valve plate
After upper two set grooves, the upper surface of the claw is higher by a certain distance than the upper surface of the valve plate.
A kind of above-mentioned exhaust valve group for reciprocating compressor, it further includes having rivet, the exhaust valve plate, damping fin and
Limiter is fixed on by the rivet on the valve plate.
A kind of above-mentioned exhaust valve group for reciprocating compressor, the root of the exhaust valve plate, the damping fin root,
The root of the limiter is respectively equipped with the perforation of the rivet.
The present invention is as a result of above-mentioned technical pattern, and when installation, exhaust valve plate, damping fin, limiter are fixed on valve
On plate, while the claw of limiter both sides is pressed in by the platform of the horizontal stripe of cylinder head gasket and cylinder head in the groove of valve plate, this
Exhaust valve plate is reliably fixed on valve plate by sample, and exhaust valve group is avoided to loosen.Exhaust valve plate, damping fin, limiter point
The theory of integrated design, the Automated assembly of easy to exhaust valve group are not used.Set each air bleeding valve sheet on exhaust valve plate
Body is symmetrical about center line, and when air bleeding valve opens or closes, air bleeding valve entirety stress is relatively uniform, to improve exhaust
The reliability of valve, the commercial compressor especially suitable for High cooling power.
