Technical field
It is specifically a kind of to be used for reciprocating compressor, make the utility model relates to arrive technical field of refrigeration compressors
The exhaust valve group of cryogen discharge cylinder.
Background technique
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,
The intracorporal refrigerant of shell enters cylinder.When piston is moved to cylinder head, the pressure in cylinder be will increase；When the pressure in cylinder
When power is greater than shell intracorporal pressure, inlet valve is closed；When the pressure in cylinder continues growing and is greater than the pressure in discharge chamber,
Exhaust 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 circulation start.Like this, the pressure in reciprocating compressor cylinder constantly changes, so as to cause inlet valve and
The opening and closing of exhaust valve.
In household compressor field, since refrigerating capacity is little, the arrangement of an air entry and an exhaust outlet is generallyd use
Mode can satisfy requirement of the user to Performance And Reliability.And in the compression of commercial compressor field, especially High cooling power
Machine, needs to increase the area of air entry and exhaust outlet, and designer would generally arrange multiple air entries and exhaust outlet on valve plate.
Due to the limitation in space, the rigidity of suction valve chip and exhaust valve plate often will increase, but can lose the power of some valve blocks 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

Air valve plate, damping fin, limiter, cylinder head gasket and cylinder head, the exhaust valve plate, damping fin and limiter successively stack solid
It is scheduled on the valve plate, the exhaust valve plate is equipped with exhaust valve, and the exhaust valve is covered on exhaust set on the valve plate
On mouth；The two sides of the limiter are respectively equipped with claw, and the claw is pressed respectively is set to two grooves set on the valve plate
In, the cylinder-top gasket on piece is equipped with two horizontal stripes and is pressed on the claw of the limiter two sides respectively, the cylinder
It covers and sets there are two platform and be pressed on two horizontal stripes set by the cylinder-top gasket on piece respectively.
A kind of above-mentioned exhaust valve group for reciprocating compressor, sets that there are two exhaust valve, Mei Gesuo on the exhaust valve plate
It is symmetrical about center line to state exhaust valve itself；It is set on the valve plate there are two the exhaust outlet, two exhaust 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 are set there are two reed.
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, claw set by the limiter two 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 the valve plate by the rivet.
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 utility model is due to using above-mentioned technical pattern, and when installation, exhaust valve plate, damping fin, limiter are fixed
On valve plate, while the claw of limiter two sides is pressed in the groove of valve plate by the platform of the horizontal stripe of cylinder head gasket and cylinder head
In, reliably exhaust valve plate is fixed on valve plate in this way, exhaust valve group is avoided to loosen.Exhaust valve plate, damping fin, limit
The theory of integrated design, the Automated assembly of easy to exhaust valve group has been respectively adopted in device.Set each exhaust on exhaust valve plate
Valve itself is symmetrical about center line, and when exhaust valve opens or closes, exhaust valve entirety stress is relatively uniform, to improve
The reliability of exhaust valve, the commercial compressor especially suitable for High cooling power.
