Abstract
The invention discloses a valve plate of a refrigerating compressor. An air-sucking buffer area, an air-sucking linear area and an air-sucking transition area are sequentially arranged on an air-sucking flow passage of an air sucking hole. The air-sucking buffer area is arranged on the reverse side of the valve plate, and the air-sucking transition area is frustum-shaped. The long bottom edges of the frustum-shaped air-sucking transition area are positioned on the front face of the valve plate while the short bottom edges of the same are connected with the air-sucking linear area. An air-exhausting buffer area and an air-exhausting transition area are sequentially arranged on an air-exhausting flow passage of a second air exhausting hole. The air-exhausting buffer area is positioned on the reverse side of the valve plate and comprises at least two sections of curved surfaces. The air-exhausting transition area is frustum-shaped. The long bottom edges of the frustum-shaped air-exhausting transition area are positioned on the front face of the valve plate while the short bottom edges of the same are connected with the air-exhausting buffer area. The air-sucking buffer area is added on the flow passage of the air sucking hole, so that coolant can be effectively buffered before entering an air sucking system, flow pulsation of the coolant entering the air sucking system is lowered, and pressure loss caused by the flow pulsation is reduced; cross sections of air-exhausting-hole flow passages are variable, so that air turbulence is reduced.

The present invention is achieved by the following technical solutions, the present invention includes plate, and the surrounding of described plate is provided with connecting through hole, and plate is provided with suction port, first row pore and second row pore; On the air-breathing runner of described suction port, be provided with successively air-breathing buffer area, air-breathing linearity sector and air-breathing transition zone, described air-breathing buffer area is positioned at the reverse side of plate, air-breathing transition zone is taper type, and the long base of described air-breathing transition zone frustum is positioned at the front of plate, and short base is connected with air-breathing linearity sector; On the grate flow channel of described second row pore, be provided with successively exhaust buffer area and exhaust transition district, described exhaust buffer area is positioned at the reverse side of plate, exhaust buffer area comprises at least two sections of curved surfaces, exhaust transition district is taper type, the long base of described exhaust transition district frustum is positioned at the front of plate, and short base is connected with exhaust buffer area.
The cross section of described air-breathing buffer area is circular, oval, square or annular, and the degree of depth of described air-breathing buffer area is 0.2～2.0mm.
As one of optimal way of the present invention, the frustum height of described air-breathing transition zone is 0.2～1.5mm, and cone angle is 30～90 °.
As one of optimal way of the present invention, the diameter of described air-breathing linearity sector is 3～10mm.
As one of optimal way of the present invention, the cross section of the grate flow channel of described second row pore is followed successively by the conical surface, cambered surface, planarea and cambered surface along the front of plate to reverse side.
As one of optimal way of the present invention, the diameter of the planarea of described second row pore is 3～8mm.
As one of optimal way of the present invention, the frustum height in described exhaust transition district is 0.2～1.5mm, and cone angle is 30～90 °.
The back side of described second row pore is provided with exhaust valve plate mounting groove.
The present invention has the following advantages compared to existing technology: the present invention utilizes the variation in the cross section in propagation of sound, the change that produces acoustic impedance causes sound reflection and reaches the object that reduces noise, increase buffer area, suction port place at suction port, before making refrigeration agent enter suction system, effectively cushioned, reduce refrigeration agent and enter the gas of suction system, and reduce the pressure loss that gas produces; On the runner of suction port, increase air-breathing transition zone, reduce the pressure loss that refrigeration agent produces in suction system side, and reduced the generation of turbulence; Exhaust port runner softening design, exhaust port cross section of fluid channel is variable cross section, by a series of curved surface rounding ofves, can reduce exhaust pressure loss, and reduces the generation of turbulence.
