Description
Technical field
The present invention relates to it is a kind of for close refrigeration compressor by refrigerant suck cylinder device, specifically one
Air-breathing valve group of the kind 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
Technical problem to be solved by the present invention lies in proposition one kind, and refrigerant can be made to flow more smooth, functional reliability
It is higher, 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 invention includes crankcase, valve plate
Gasket, suction valve chip and valve plate, the valve plate gasket, suction valve chip and valve plate stack successively to be connected on the crankcase, institute
Inlet valve there are two being laid on suction valve chip is stated, the shape of described two inlet valves is symmetrical along the center line of itself respectively, described
It is set on valve plate there are two air entry, two set inlet valves are respectively overlay in the two of the valve plate on the suction valve chip
On a air entry.
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 present invention due to the above structure, it can increase the area of air entry and exhaust outlet to the maximum extent, make system
Cryogen flowing it is more smooth, reduce flow losses, while can make inlet valve have smaller rigidity so that the opening of inlet valve and
It closes more efficient.When each inlet valve is opened, the stress uniform stressed of inlet valve root both sides, each suction valve chip is closed
When, 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.

Specific implementation mode
As shown in figures 1 to 6, air-breathing valve group of the present invention includes crankcase 1, valve plate gasket 2, suction valve chip 3 and valve plate 4.
When installation, valve plate gasket 2, suction valve chip 3 and valve plate 4 are positioned on crankcase 1 successively as shown in Figure 6, it then will with screw
These components are fixed on crankcase 1.
As shown in Fig. 2, being laid on suction valve chip 3, there are two inlet valve 3a, 3b, the shape difference of two inlet valves 3a, 3b
Center line along itself is symmetrical.
As shown in figure 5, being set on valve plate 4 there are two air entry 4a, 4b, two inlet valve 3a, 3b difference on suction valve chip 3
It is covered on two air entries 4a, 4b of valve plate 4.
As shown in figure 3, two outside root areas of the crankcase 1 on the region 1a, 1b of cylinder face with inlet valve 3a, 3b
The corresponding position 3c, 3d is set there are two slot, outside root area 3c, 3d for avoiding two inlet valves 3a, 3b.This this two
The shape of a slot can be straight trough, can also be skewed slot, arc groove etc..
As shown in figure 4, position corresponding with two outsides root area 3c, 3d of inlet valve 3a, 3b on valve plate gasket 2
2a, 2b are set there are two slot, outside root area 3c, 3d for avoiding two inlet valves 3a, 3b.
As shown in Fig. 2, being set on suction valve chip 3, there are two exhaust outlet 3e, 3f, exhaust outlet 3e to be located at inlet valve 3a enclosing regions
Interior, exhaust outlet 3f is located in inlet valve 3b enclosing regions.
Contrast test is carried out with prior art, the present invention is with following obvious prominent substantive distinguishing features and shows
Write progress：1, the area for increasing air entry and exhaust outlet to the maximum extent keeps refrigerant flowing more smooth, reduces flowing damage
It loses.2, the shape of suction valve chip and position are laid so that inlet valve allows suction valve chip more easily to open with smaller rigidity
And closing, improve compressor efficiency.3, each inlet valve itself is symmetrical about center line, and each suction valve chip is opened
When, the stress uniform stressed of inlet valve root both sides, when each suction valve chip is closed, the slap at left and right sides of the head of inlet valve
Speed is identical, and when such inlet valve works, reliability is higher.Four, installation air-breathing valve group is more convenient, need not increase additional
Part.
