Abstract
The utility model relates to a combined type air valve structure of an air compressor for automobiles, which is characterized in that the combined type structure of an inlet valve and an air outlet valve is formed by adopting a reed air inlet valve and a plate valve air outlet valve are adopted, and simultaneously a part combined with the air inlet valve is added to push away the sheet type automatic pressure reducing device of an air sucking valve. As a result, the working performance of an air compressor for automobiles is increased further, and the service life is extended relatively.
Description
The utility model relates to a kind of combined type air valve structure of air compressor for vehicle.
Existing air compressor for vehicle, its inlet and outlet valve all adopts tabular valve or Reed Valve, facts have proved, and the static sealing and the heat resistance of tabular valve are better, but volumetric efficiency is low, influences air displacement; And Reed Valve is improving aspect volumetric efficiency and the reduction specific power more superiorly than tabular valve, but sealing, heat resistance are relatively poor relatively.Therefore, every single air compressor for vehicle with tabular valve or Reed Valve all exists certain deficiency on the performance.
The purpose of this utility model is to provide a kind of combined type air valve structure of air compressor for vehicle.
The utility model has mainly adopted tongue suction valve and the combined technological scheme of plate valve outlet valve, be that suction valve adopts Reed Valve, outlet valve adopts tabular valve, both combinations had both overcome shortcoming separately, the advantage that has possessed two kinds of valves again, make it more adapt to residing working environment, thereby the performance of air compressor is improved greatly, prolong working life relatively.In addition, regulate for the automatic pressure of realizing air compressor for vehicle, the utility model has designed and has partly backed down the automatic loose pressure device of Aspirating valves chip, makes it combined with the tongue suction valve.
Below in conjunction with accompanying drawing the utility model further is illustrated.Accompanying drawing is a summary structural drawing of the present utility model.Can see that from accompanying drawing the combined type air valve structure of air compressor for vehicle of the present utility model comprises that the combined and tongue suction valve of automatic loose pressure device and tongue suction valve and plate valve outlet valve are combined.The tongue suction valve is made up of inlet valve seat 2, the close circle 3 of suction valve seat cushion, tongue air-intake valve plate 4 and sunk screw 14; The plate valve outlet valve is made up of delivery valve seat 9, the close circle 10 of outlet valve seat cushion, outlet valve guide holder 11, tabular exhaust valve plate 12, exhaust valve spring 13, wavy spring packing ring 15, exhaust joint 16, the close circle 17 of pad, hollow bolt 18.Because suction valve has reduced intake resistance after adopting Reed Valve, has accelerated aeration speed, has improved volumetric efficiency, has reduced specific power.After outlet valve adopts tabular valve, make the static sealing of its outlet valve and heat resistance all better.Therefore, the knockdown air inlet and exhaust valve structure of newly-designed tongue suction valve and plate valve outlet valve makes the service behaviour of air compressor for vehicle obtain further to improve, and prolonged working life relatively.From accompanying drawing, further see, automatic loose pressure device is installed on the cylinder head 1 of main frame, it is made up of pressure loosening valve seat 5, pressure loosening valve sheet 6, pressure loosening valve spring 7, the close circle 8 of pressure loosening valve seat cushion, pressure loosening valve assembly 19, the close circle 20 of pad, automatic loose pressure device and tongue suction valve are combined, thereby component part is backed down the automatic loose pressure device of Aspirating valves chip.Automatic loose pressure device is connected with the gas receiver of air compressor for vehicle main frame by a suction tude 21, when gas receiver internal air pressure during greater than certain amount (as 0.7MPa), pressurized air in suction tude enters automatic loose pressure device promotes pressure loosening valve sheet 6 and moves down, pressure loosening valve is opened, and the pressurized air in the cylinder borrows pressure difference to enter in the atmosphere through main frame admission line 22; When the air pressure in the gas receiver is lower than certain amount (as 0.55MPa), pressure loosening valve sheet 6 returns in the automatic loose pressure device, thus realized the automatic adjusting of pressure.
Compare with the inlet and outlet valve arrangement of existing air compressor for vehicle, it is few that the Combined air valve structure of air compressor for vehicle of the present utility model has the pressure loss, and capacity is big, and upper gas is fast, saves energy consumption, and compact conformation is made the advantages such as easy to maintenance.
