Embodiment
Describe embodiment of the present utility model below in detail, described embodiment's example is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment who is described with reference to the drawings, be exemplary, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
First by reference to the accompanying drawings specifically describe the lift stopper 100 according to the utility model embodiment's compressor below.
As shown in Figure 1 to Figure 3, according to the lift stopper 100 of the utility model embodiment's compressor, lift stopper 100 be located at compressor exhaust valve plate top with restriction exhaust valve plate lift, lift stopper 100 comprises body 10.Wherein, the lower surface of body 10 is provided with the vibration damping portion 20 for noise-and-vibration-reduction.
Thus, according to the lift stopper 100 of the utility model embodiment's compressor, by be provided for the vibration damping portion 20 of vibration and noise reducing below body 10, the impact of the exhaust valve plate that can alleviate compressor to lift stopper 100, thereby reduce the running noise of compressor, and improve the working life of exhaust valve plate.
It should be noted that, as shown in Figure 3, compressor has bearing support 40, and bearing support 40 is provided with exhaust port 41.One end of exhaust valve plate 30 is fixed on bearing support 40, and the other end is positioned on exhaust port 41, can open and close exhaust port 41.For there is the sheet structure of resiliently deformable in exhaust valve plate 30, lift stopper 100 is arranged on the top of exhaust valve plate 30 to a certain extent, and one end of lift stopper 100 is fixed on bearing support 40.
Exhaust valve plate 30 makes exhaust port 41 in closed state under normal conditions, while having air-flow to pass through in exhaust port 41, air-flow can produce pressure to exhaust valve plate 30, makes exhaust valve plate 30 that deformation occur and opens exhaust port 41, after air-flow passes through, exhaust valve plate 30 is replied original state.Exhaust valve plate 30 moves reciprocatingly and opens and closes exhaust port 41 under airflow function.Lift stopper 100 is mainly used in limiting the degree that exhaust valve plate 30 opens, and namely lift stopper 100 can be controlled the maximum lift height of exhaust valve plate 30.
Because exhaust valve plate 30 can be subject to the impact of lift stopper 100, the impact of 30 pairs of lift stoppers 100 of exhaust valve plate not only can produce noise, and exhaust valve plate 30 is under long-term impact, the surface structure of exhaust valve plate 30 can be damaged or crack, can affect the structural integrity of exhaust valve plate 30, shorten the working life of exhaust valve plate 30, reduce the usability of compressor.
And according to the utility model embodiment's lift stopper 100, at the lower surface of body 10, being provided with can be for the vibration damping portion 20 of noise-and-vibration-reduction, one end distortion of exhaust valve plate 30 is upturned while contacting with vibration damping portion 20, impact force between vibration damping portion 20 energy buffering exhaust valve blocks 30 and lift stopper 100, thus the noise producing by impacting reduced.The impact that the surface of exhaust valve plate 30 is subject to simultaneously diminishes, and can improve the working life of exhaust valve plate 30, the more reliable performance of compressor.
Vibration damping portion 20, in the not restriction of distribution area of body 10 lower surfaces, when one end of exhaust valve plate 30 distortion is upturned, carries out with exhaust valve plate 30 condition effectively contacting as long as vibration damping portion 20 can meet it.For example, vibration damping portion 20 can partly cover the lower surface of body 10.Preferably, according to an embodiment of the present utility model, vibration damping portion 20 covers the lower surface of body 10.Thus, one end of exhaust valve plate 30 distortion is upturned while contacting with vibration damping portion 20, and vibration damping portion 20 is buffering exhaust valve block 30 and lift stopper 100 impact force between the two largely, strengthens the cushioning effect of vibration damping portion 20.
According to an embodiment of the present utility model, vibration damping portion 20 forms flexible anti-vibration lamellar body.For example, vibration damping portion 20 can be the materials such as rubber.Preferably, according to an embodiment of the present utility model, vibration damping portion 20 forms Cuprum alloy lamellar body.Thus, the softer Cuprum alloy of material can reduce the rigid impulse of 30 pairs of lift stoppers 100 of exhaust valve plate.
Further, according to an embodiment of the present utility model, the Cuprum alloy lamellar body that vibration damping portion 20 is porous structure.Particularly, copper vibration damping portion 20 can be by powder metallurgy forming.Thus, the internal microstructure of vibration damping portion 20 is porous structure, and the material of porous structure has the effect of good vibration and noise reducing, the pore size of vibration damping portion 20 and porosity ratio can be controlled by the parameter in adjusting metal granule size and manufacturing process simultaneously, thereby can reasonably adjust the structure of vibration damping portion 20.
The effect of body 10 is lifts of restriction exhaust valve plate 30, need to have certain rigidity.In an embodiment of the present utility model, body 10 forms rigid limit lamellar body.Further, body 10 forms ferro-alloy lamellar body.Thus, the body 10 of irony has guaranteed good riveted joint manufacturing, endurance and the resistance to creep properties of lift stopper 100.
It should be noted that, riveted holes 11 can be set in one end of lift stopper 100, rivet 50 is through riveted holes 11, and lift stopper 100 can be riveted with bearing support 40, thereby one end of lift stopper 100 is fixed.
Be understandable that, both can form lift stopper 100 by modes such as bonding, mechanical connections copper vibration damping portion 20 and the body of irony 10.Alternatively, according to an embodiment of the present utility model, vibration damping portion 20 is compounded to form with body 10 one.Thus, both are firmly connected by certain combination process, can to make vibration damping portion 20 and body 10, the more reliable performance of lift stopper 100, and the energy of the further impact-absorbing vibration of the interface energy that is connected with body 10 of the different vibration damping portion 20 of material, improve the effect of the noise reduction energy-absorbing of lift stopper 100.
The thickness of vibration damping portion 20 is not particularly limited, and alternatively, according to an embodiment of the present utility model, the pass of the total thickness D of the thickness Da of vibration damping portion 20 and body 10 and vibration damping portion 20 is: 0.2D≤Da≤0.8D.
According to the utility model embodiment's compressor, comprise the lift stopper 100 that above-described embodiment is described.Because the lift stopper 100 according to the compressor of the utility model above-described embodiment has above-mentioned technique effect, therefore according to the utility model embodiment's compressor, also there is corresponding technique effect, that is: the noise that the lift stopper 100 of compressor produces is little, the long service life of exhaust valve plate 30, the more reliable performance of compressor.
According to the associative operation of the utility model embodiment's compressor, be that those of ordinary skills easily understand and obtain, therefore no longer repeat.
