Abstract
The utility model provides an inlet and outlet valve for air compressor with a novel structure, comprising an inlet reed valve, an air exhaust circular valve and a valve board. The valve board is provided with a relative channel. Wherein, the inlet reed valve is composed of an inlet leaf spring valve slice and a valve shim and tightly fixed on the undersurface of the valve board through a spring gasket and a screw. The air exhaust circular valve is composed of an air exhaust circular valve slice, an exhaust valve spring and a lift limiter and tightly fixed on the upper surface of the valve board through a screw and a nut. Because the inlet valve adopts the reed valve, and the exhaust valve adopts the circular valve, the valve has the advantages of small volume of extra gap, good high-temp resisting and high speed access. Therefore, the comprehensive performance of the inlet and outlet valve for air compressors is raised.
Description
Technical field
The utility model belongs to a kind of valve, is specifically related to the air compressor air inlet and exhaust valve of a kind of use on air compressor.
Background technique
Existing air compressor air inlet and exhaust valve, or all adopt the Reed Valve structure, clearance volume is little but high temperature-resistant high-speed is poor slightly; All adopt the ring valve structure, high temperature-resistant high-speed is good but clearance volume is big.
Summary of the invention
Task of the present utility model provides a kind of air compressor air inlet and exhaust valve, and is little but high temperature-resistant high-speed is poor slightly to solve clearance volume, or high temperature-resistant high-speed is good but problem that clearance volume is big.
The utility model has adopted following technological scheme:
The utility model is made up of air inlet Reed Valve, exhaust ring valve and valve plate, the air inlet Reed Valve be fastened on valve plate below, the exhaust ring valve be fastened on valve plate above, valve plate is provided with corresponding passage.Wherein: the air inlet Reed Valve is made up of air inlet reed valve plate, valve gasket, by spring washer, screw be fastened on valve plate below; The exhaust ring valve is made up of exhaust ring-shaped valve, exhaust valve spring, lift limiter, by screw, nut be fastened on valve plate above; Gas-entered passageway on the valve plate is one group of parallel straight trough, and the exhaust passage on the valve plate is concentric annular groove or concentric annular hole; The exhaust ring valve can be one or two, and the exhaust passage on the valve plate also is one group or two groups.
Use the utility model, can make it have the advantage that clearance volume is little, high temperature-resistant high-speed is good concurrently, improve the combination property of air compressor air inlet and exhaust valve.
Description of drawings
Fig. 1 is the utility model sectional structure schematic representation.
Fig. 2 sheds plan structure schematic representation behind the cylinder cap for the utility model.
Embodiment
Accompanying drawing is depicted as an embodiment of the present utility model, but the content of model utility more than that.
1 is valve plate among the figure, and 2 are the exhaust ring-shaped valve, and 3 is exhaust valve spring, and 4 is lift limiter, and 5 is screw, and 6 is nut, and 7 is cylinder cap, and 8 are the air inlet reed valve plate, and 9 is valve gasket, and 10 is spring washer, and 11 is screw.A is the gas-entered passageway on the valve plate, and b is the exhaust passage on the valve plate, and A is that air-inlet cavity, B are exhaust cavity.
The air compressor air inlet and exhaust valve is made up of air inlet Reed Valve, exhaust ring valve and valve plate 1.Wherein the air inlet Reed Valve is made up of air inlet reed valve plate 8, valve gasket 9, by spring washer 10, screw 11 be fastened on valve plate 1 below; Ring valve is made up of exhaust ring-shaped valve 2, exhaust valve spring 3, lift limiter 4, by screw 5, nut 6 be fastened on valve plate 1 above; Gas-entered passageway a on the valve plate 1 is one group of straight trough, and the exhaust passage b on the valve plate 1 is the concentric annular groove, and is better for making exhaust effect, and two exhaust ring valves are installed, and correspondingly the exhaust passage b on the valve plate 1 is two groups of concentric annular grooves; Cylinder cap 7 forms air-inlet cavity A, exhaust cavity B with valve plate 1.
When the air pressure in the air-inlet cavity A was higher than pressure in the air compressor cylinder, this pressure difference promoted air inlet reed valve plate 8 and opens downwards, and the air in the air-inlet cavity A enters cylinder through the gas-entered passageway a on the valve plate 1, finishes intake process; During pressure in the air pressure in the air compressor cylinder is higher than exhaust cavity B, this pressure difference overcomes the spring force of exhaust valve spring 3, promote exhaust ring-shaped valve 2 and upwards open, the air in the cylinder enters exhaust cavity B through the exhaust passage b on the valve plate 1, finishes exhaust process.
