Abstract
The invention relates to parts of a refrigerating compressor and provides an air suction valve sheet for a sealed refrigerating compressor cylinder. The air suction valve sheet is provided with a reed, the reed is divided into three sections, namely a fixed section, a bent section and a sealed section in the long axis direction, and the front end of the sealed section is arc-shaped. The air suction valve sheet for the sealed refrigerating compressor cylinder is characterized in that an isosceles triangle through hole is arranged on the bent section of the reed, the bottom edge of the isosceles triangle through hole is arranged close to the sealed section, the central line of the isosceles triangle through hole is coincided with the central line of the reed in the length direction, two base angles of the isosceles triangle through hole are small round angles, and the apex angle of the isosceles triangle is a large round angle. The air suction valve sheet for the sealed refrigerating compressor cylinder is suitable in rigidity, reduces valve sheet opening and closing loss, is rapid in response, improves air suction efficiency, and particularly suitable for air suction and discharge system in a small sealed refrigerating compressor.
Description
(i) technical field: the present invention relates to the refrigeration compressor component, especially a kind of air suction valve for air cylinder of sealed refrigerating compressor.
(ii) background technique: at present, in refrigerator hermetically sealed compressor industry, valve plate is as the closed end of compression cylinder, have a suction port and exhaust port at least, major control flowing to of gas and is flowed out, the suction port of valve plate and suction valve chip form Aspirating valves and are controlling flowing to of air-flow, and valve plate exhaust port and exhaust valve plate form the outflow that outlet valve is controlled gas, common compressors suction valve chip, seal section is the circle that diameter is little, the holding part width dimensions is narrower, middle bending section is massive structure, when air-breathing, lift is large, flexural stress is large, for guaranteeing suction valve chip fatigue strength, thickness just can not be too thin, rigidity is also just larger, when the each open and close of suction valve chip, consumed energy is larger like this, affect press efficiency.
(iii) summary of the invention: it is larger that purpose of the present invention will overcome existing suction valve chip bending section rigidity exactly, and the problem of valve block consumption in operation energy considerable influence compressor efficiency, provide a kind of air suction valve for air cylinder of sealed refrigerating compressor.
The present invention is directed to existing two kinds of absorption valve plate structure forms and proposed two kinds of solutions:
Scheme one: this suction valve chip has reed, it is holding part, bending section, seal section that reed is divided into three sections on long axis direction, the front end of seal section is circular arc, it is characterized in that: have the isosceles triangle through hole on the bending section of described reed, the base of triangle through hole is arranged by seal section, the center line of triangle through hole overlaps to center line with the length of reed, and two base angles of triangle through hole are small round corner, and leg-of-mutton drift angle is Rouno Cormer Pregrinding Wheel.
Scheme two: this suction valve chip has dunnage, on dunnage, minute four jiaos of punching have four mounting holes, the middle part punching of dunnage has reed, it is holding part, bending section, seal section that reed is divided into three sections on long axis direction, the front end of seal section is circular arc, it is characterized in that: have the isosceles triangle through hole on the bending section of described reed, the base of triangle through hole is arranged by seal section, the center line of triangle through hole overlaps to center line with the length of reed, and two base angles of triangle through hole are small round corner, and leg-of-mutton drift angle is Rouno Cormer Pregrinding Wheel.
The size of seal section on the reed long axis direction described in the present invention program one, two on reed is less than the size on short-axis direction.
Described in the present invention program one, two, two waists of triangle through hole are designed to straight line or camber line limit simultaneously, and the base of triangle through hole is straight line or camber line limit.
Described in the present invention program one, two, the profile of reed is rectangular or trapezoidal, or fan-shaped.
The tail end of reed holding part described in the present invention program one and a side have positioning groove.
The present invention is because the seal section width is large, suction port is large, bending section at valve block has the triangle through hole simultaneously, make the bending section stiffness degradation, when air-breathing, only need little lift just can suck enough gas flows, such design just can reduce valve block folding loss, makes the open and close of valve block flexible, reacts fast, loss is little, has finally improved gettering efficiency.The suction and discharge system be particularly suitable in the miniaturization sealed refrigeration compressor is used.
