Abstract
The utility model relates to a vibration-absorbing baffle for a rotary compressor. The vibration-absorbing baffle is connected with a reed valve plate of the rotary compressor; the reed valve plate is connected on a valve seat; and one or more vibration-absorbing cavities are arranged at the part of the baffle, which is in contact with the reed valve plate. Compared with the prior art, contact force generated by the impact of the valve plate on the baffle can be reduced with the adoption of the vibration-absorbing baffle; and the chattering when the valve plate is opened can be reduced, so as to achieve the aims of improving the reliability of the valve plate, reducing exhaust flow loss of the compressor and improving the efficiency of the compressor; and meanwhile, the exhaust noise caused by the compressor can be further reduced.
Description
Technical field
The utility model relates to a kind of rotary compressor exhaust structure, especially relates to a kind of rotary compressor and uses the absorbing baffle plate.
Background technique
The exhaust structure of rotary compressor is the Reed Valve structure.Open moment when valve block, valve block is understood violent impingement baffles, bigger contact stress can occur between valve block and the baffle plate, has reduced the reliability of valve block, even possibly cause valve block to break.
In the exhaust process of compressor, reed valve plate can not be fully and baffle plate fit, valve block is constantly flutter between baffle plate and valve seat, has not only increased the fluid resistance losses of exhaust, and has reduced the reliability of valve block, even caused the valve block fatigue fracture.
The model utility content
The purpose of the utility model is exactly that a kind of the reduce contact force of valve block impingement baffles, the flutter when valve block is opened and the exhaust air flow loss of compressor are provided for the defective that overcomes above-mentioned existing technology existence, improves the reliability of valve block and the rotary compressor of compressor efficiency and uses the absorbing baffle plate.
The purpose of the utility model can realize through following technological scheme:
A kind of rotary compressor is used the absorbing baffle plate, is connected with the reed valve plate of rotary compressor, and reed valve plate is connected on the valve seat, offers one or more absorbings chamber in the contact position of baffle plate and reed valve plate.
Described absorbing chamber is
bowl configurations.
Described absorbing chamber is circle or quadrilateral or polygonal.
Compared with prior art, the utility model can reduce the contact force of valve block impingement baffles, the flutter in the time of can reducing the valve block unlatching simultaneously, thus reach the reliability that both improves valve block, reduce the exhaust air flow loss of compressor again, improve the purpose of compressor efficiency.Simultaneously, can also reduce the exhaust sound of compressor.
Description of drawings
Fig. 1 is the main TV structure schematic representation of the utility model;
Fig. 2 is the plan structure schematic representation of the utility model;
Fig. 3 is the absorbing principle schematic of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
Rotary compressor is used the absorbing baffle plate, shown in Fig. 1-2, is connected with the reed valve plate of rotary compressor; Reed valve plate is connected on the valve seat; Offer one or more absorbings chamber 1 at the position that baffle plate contacts with the valve block head, promptly one or more bowl configurations, absorbing chamber 1 is provided with 3 in the present embodiment.Absorbing chamber 1 is circle or quadrilateral or polygonal, is circular in the present embodiment.Can reduce the contact force of valve block impingement baffles, the flutter in the time of can reducing the valve block unlatching simultaneously, thus reach the reliability that both improves valve block, reduce the exhaust air flow loss of compressor again, improve the purpose of compressor efficiency.Simultaneously, can also reduce the exhaust sound of compressor.The valve block head is the valve block position that covers the valve seat exhaust port.Through the absorbing chamber is set on baffle plate, i.e. bowl configurations can reduce the contact force of valve block impingement baffles; Flutter in the time of can reducing simultaneously the valve block unlatching; Thereby reach the reliability that both improves valve block, reduce the exhaust air flow loss of compressor again, improve the purpose of compressor efficiency.
1) valve block just opened instantaneous, the absorbing chamber is equivalent to gas spring or air cushion, prevents the violent impingement baffles of valve block.Thereby improve the valve block reliability, reduce the noise of valve block impingement baffles.
2) when the valve block complete opening; Owing to there is high speed airflow to flow through from the valve block head edge, can produce local depression in the absorbing chamber, make the gas pressure in the absorbing chamber above the valve block head less than the gas pressure below the valve block; The valve block head just receives gas differential pressure power upwards; This difference force is adjacent on baffle plate valve block, thereby suppresses the flutter of valve block, makes exhaust more smooth and easy.Thereby improve reliability, the reduction exhaust noise of compressor performance and valve block.
The absorbing principle can be analyzed with hydromechanical Bernoulli's equation, and is as shown in Figure 3.Receive the effect of the stagnation P1 of air-flow below the valve block head, high speed airflow is skimmed over valve block, produces pressure P 2 at the edge of valve block; P1＞P2 here, P2 acts on the gap location between valve block and the baffle plate, can make that the pressure P 3 in the absorbing chamber reduces gradually; Up to P3=P2, thereby make the valve block top and bottom difference that is under pressure, thus the difference force effect that produces P1-P3; Valve block is adjacent to baffle plate, thereby reduces the flutter of valve block.
Claims (3)
1. a rotary compressor is used the absorbing baffle plate, is connected with the reed valve plate of rotary compressor, and reed valve plate is connected on the valve seat, it is characterized in that, offers one or more absorbing cavity configuration in the contact position of the head of baffle plate and reed valve plate.
2. a kind of rotary compressor according to claim 1 is used the absorbing baffle plate, it is characterized in that, described absorbing chamber is a bowl configurations.
