Embodiment 1
As shown in Figs 1-4, a kind of exhaust valve plate component of the invention, comprising:
Exhaust valve plate is adapted to be attached on the first object for offering exhaust outlet 7, and knot is vented at the exhaust outlet 7
Shu Shi, the exhaust valve plate are mobile towards closing direction rapidly under the action of reset force；
Bolster, when exhaust valve plate is closed, cushion effect is acted on the exhaust valve plate, and the side of the cushion effect
To contrary with the reset force, the size of the cushion effect is less than the size of the reset force.
The exhaust valve plate component of above structure can close initial speed per hour in exhaust valve plate due to there is reset force
Degree is big, and closing does not postpone rapidly, meanwhile, the effect of bolster can make exhaust valve plate become smaller rapidly in closing end speed, reduce
Impact of the exhaust valve plate to exhaust outlet 7 extends the service life of exhaust valve plate to improve the reliability of exhaust valve plate.In order to
It is easy to understand, the first object is the upper flange of compressor in the present embodiment, and certainly, the first object can be other structures, no
It is limited to the upper flange of compressor.
When exhaust valve plate is the exhaust valve plate of elasticity, reset force can be provided by the elastic force of exhaust valve plate itself.Certainly,
In the present embodiment, it is also preferable to include the return unit that the exhaust valve plate side is arranged in, the reset force is by the return unit
It provides.
The return unit and the bolster can be elastic component, can also be magnetic part, or one of them is
Elastic component, wherein another be set as magnetic part.In the present embodiment, at least a part of by magnetism on the preferably described exhaust valve plate
Structure 2 is constituted；
The return unit is the first magnetic part 6, the magnetic force that first magnetic part 6 generates the magnetic texure 2
Form the reset force；
The bolster is the second magnetic part 8, the magnetic force that second magnetic part 8 generates the magnetic texure 2
Form the cushion effect.According to the magnet characteristic that identical charges repel each other, there is a natural attraction between the sexes, it is arranged by the direction of different magnetism, it can be to it
Speed plays adjustment effect when exhaust valve plate switchs, to solve the contradiction of the prior art.
As shown in Figure 3-4, it is preferable that first magnetic part 6 is arranged in the exhaust valve plate far from first object
Side, second magnetic part 8 is arranged on first object, and the magnetic texure 2 and first magnetic portion
The magnetic force of part 6 repels each other setting, and the magnetism of the magnetic texure 2 and second magnetic part 8 is repelled each other setting.The knot that identical charges repel each other
Structure is easier to be arranged, and structure is more simple.
As shown in Figs. 1-2, the preferably described exhaust valve plate includes the first valve block section 3 suitable for connecting with the first object, and
Suitable for closing the second valve block section 1 of the exhaust outlet 7, the setting of magnetic texure 2 is in the first valve block section 3 and described second
Between valve block section 1, the first valve block section 3 is connect with the second valve block section 1.First valve block section 3 and the second valve block section 1 can
For rigid plastics PTFE material, it can also be casting material, the material of suitable dual extension-compression modulus can be selected by actual demand.
The magnetic texure 2 is the folding folding structure of length direction along the valve block.It in this way can be according to reality
The structure of the upper flange on border is adjusted the length and thickness of its own, and exhaust valve plate is enable to be applicable in the upper method of various sizes
Orchid, to improve the versatility of exhaust valve plate.
It is preferred that the magnetic texure 2 includes several magnetic pieces, it is flexibly connected between the end of adjacent two magnetic piece, with
Make the magnetic texure 2 in folding wavy.In the present embodiment, magnetic piece is magnetic links.Magnetic piece and magnetic piece it
Between connection type can for mechanical connection, welding, melting or chemical reaction etc. modes.
As interchangeable embodiment, the magnetic texure 2 can also be magnetized compliant member.It so also can be real
The gathering and expansion of existing magnetic texure 2, to meet length and the thickness of different demands to cooperate upper flange.
It further, further include the lift of valve plate limiter 5 limited to the exhaust valve plate opening degree.
It is preferred that first magnetic part 6 is arranged on the lift of valve plate limiter 5, this spline structure is more simple tight
It gathers.
Specifically, the lift of valve plate limiter 5 is equipped with the first connecting hole, the exhaust valve plate is equipped with the first connection
Hole 4 sequentially passes through first connecting hole, the first connecting hole 4 for the exhaust valve plate, the lift of valve plate by fastener 10
Limiter 5 is fixed on first object.
A kind of compressor of the invention is equipped with exhaust valve plate component as described above at the exhaust outlet 7 of the compressor.This
The compressor of invention has above-mentioned exhaust valve component, not only will not influence the exhaust resistance of compressor, but also can effectively be promoted
The efficiency and reliability of compressor.
When the exhaust outlet 7 of the compressor is arranged on flange 9, first object is the flange 9.
Operation logic of the invention: when compressor, which completes compression circulation, to be exhausted, exhaust valve plate is opened, compression
Gas is discharged from the exhaust outlet of flange 9, and after the completion of exhaust, exhaust valve plate is closed.At this point, due on lift of valve plate limiter 5
The magnetism of first magnetic part 6 is better than the magnetism of the second magnetic part 8 on flange valve seat, therefore works as exhaust valve plate when closed
There is the magnetic force additionally to repel each other that exhaust valve plate is closed, speed is big when exhaust valve plate closes initial to reach, and closing is not prolonged rapidly
Slow purpose.Meanwhile when exhaust valve plate is closed fastly, repel each other due to also having on flange valve seat with magnetic texure on exhaust valve plate
The second magnetic part 8, therefore meet exhaust valve plate and close end speed and become smaller rapidly, reduce impact of the exhaust valve plate to gas vent.
Although exhaust valve plate is opened, although there are also the openings that certain magnetic force hinders exhaust valve plate, since pressure at expulsion is very high,
And flange valve seat also has the second magnetic part 8 to repel each other to generate certain magnetic force, so the increase of exhaust resistance has no effect on pressure
The power (or influence is smaller, can be ignored) of contracting machine.Versatility not only can be improved in this programme, and exhaust valve plate is made to cooperate different knots
The upper flange of structure, but also the service life of exhaust valve plate can be effectively improved, the reliability of compressor is improved, has and preferably pushes away
Wide property and versatility.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
