Description
Technical field
The utility model is related to be used to close refrigeration compressor by the device of refrigerant sucking cylinder, specifically to a kind of
It is a kind of air-breathing valve group for reciprocating compressor.
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 at this moment piston is again to tail cylinder
Movement, a new cycle starts, and the inner pressure of air cylinder of reciprocating compressor constantly changes like this, 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, and can also meet requirement of the user to Performance And Reliability.In commercial compressor field, due to the refrigerating capacity of compressor
It is generally all very big, need the area for increasing air entry and exhaust outlet, designer that would generally arrange multiple air entries on valve plate
And exhaust outlet.But due to the limitation in space, often increase the rigidity of suction valve chip and exhaust valve plate, but can thus lose
The dynamic performance for falling some valve blocks reduces the working efficiency of compressor.
The Chinese invention patent of Publication No. CN104093984B discloses a kind of inlet valve for reciprocating compressor
Component, which employs the arrangements of double suction gas port and double-exhaust port, but since two inlet valves itself are not symmetric shapes, when
When suction valve chip is opened, suction valve chip root both sides stress is different, and when suction valve chip is closed, valve block head on both sides flop valve
The speed of seat is also different, and the local stress that suction valve chip is subject to can be caused to increase in this way, is easy to cause valve block is locally broken to ask
Topic.In addition two gas vents of the patent of invention are located at inlet valve area periphery on suction valve chip, and such layout designs are unfavorable
In the area for further increasing exhaust outlet, so this sucking valve group is not particularly suited for the commercial compressor of High cooling power.
Invention content
The technical problem to be solved by the utility model is to propose that one kind can make refrigerant flowing more smooth, work can
It is higher by property, and the air-breathing valve group for reciprocating compressor of compressor efficiency can be further increased.
In order to solve the above technical problems, a kind of air-breathing valve group for reciprocating compressor of the utility model include crankcase,
Valve plate gasket, suction valve chip and valve plate, the valve plate gasket, suction valve chip and valve plate stack successively is connected to the crankcase
On, there are two inlet valves for laying on the suction valve chip, and the shape of described two inlet valves is symmetrical along the center line of itself respectively,
It is set on the valve plate there are two air entry, two set inlet valves are respectively overlay in the valve plate on the suction valve chip
Two air entries on.
A kind of above-mentioned air-breathing valve group for reciprocating compressor, the crankcase on the region of cylinder face with the inlet valve
Two outsides root area corresponding position at, be respectively equipped with slot.
A kind of above-mentioned air-breathing valve group for reciprocating compressor, the shape of the set slot is straight on the crankcase
Slot, skewed slot or arc groove.
A kind of above-mentioned air-breathing valve group for reciprocating compressor, on the valve plate gasket with two outsides of the inlet valve
The corresponding position of root area is equipped with slot.
A kind of above-mentioned air-breathing valve group for reciprocating compressor, suction valve chip exhaust outlet equipped with there are two, two
The exhaust outlet is located in the enclosing region of two inlet valves.
The utility model due to the above structure, it can increase the area of air entry and exhaust outlet to the maximum extent,
Keep refrigerant flowing more smooth, reduce flow losses, while can make inlet valve that there is smaller rigidity so that inlet valve is beaten
It is open and close more efficient.When each inlet valve is opened, the stress uniform stressed of inlet valve root both sides, each suction valve chip closes
When closing, the velocity of flapping at left and right sides of the head of inlet valve is identical, and reliability is higher at runtime for such inlet valve.
