Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.
As shown in fig. 1-4, a valve plate assembly for the field of oil-free air compressors comprises a valve plate body 1, wherein both sides of the valve plate body 1 are respectively provided with an air inlet hole group 2 and an air outlet hole group 3, the air inlet hole group 2 is provided with an air inlet control assembly 4 on the lower surface of the valve plate body 1 in a matching manner, and the air outlet hole group 3 is provided with an air outlet control assembly 5 on the upper surface of the valve plate body 1 in a matching manner.
Further, the air inlet group 2 and the air outlet group 3 on the valve plate body are respectively formed by a group of semicircular round holes; the air outlet control component 5 comprises a first bolt 51, a pressure plate 52 and an air outlet valve piece 53 which are matched with each other, one end of the pressure plate 52 and one end of the air outlet valve piece 53 are fixed on the valve plate body 1 by the first bolt 51, the other end of the air outlet valve piece covers the air outlet hole group 3, and the direction of the air outlet control component is towards the side of the top cylinder cover 6; the air inlet control component 4 comprises a second bolt 41 and an air inlet valve plate 42 which are matched with each other; the second bolt 41 fixes one end of the intake valve sheet 42 to the valve plate body 1, and the other end covers the intake hole group 2, and is installed toward the piston chamber 7 side.
Further, the inlet valve plate 42 and the outlet valve plate 43 are fan-shaped. The air inlet group 2 and the air outlet group 3 are respectively of a semicircular structure consisting of four round holes.
As shown in figure 4, when the air intake valve is installed, in operation, the piston 8 moves downwards, and because the internal pressure of the piston chamber is smaller than the pressure (atmospheric pressure) in the air intake cavity of the top cylinder cover, the air intake valve plate is opened under the influence of the pressure difference, and air enters the piston chamber; along with the reduction of the pressure difference, the air inlet valve plate begins to recover slowly by the elasticity of the air inlet valve plate until the air inlet valve plate is straight and covers the hole;
the pressure in the air inlet cavity of the top cylinder cover is close to the atmospheric pressure, and the air inlet valve plate can be opened by a small pressure difference without exceeding the elasticity of the air inlet valve plate and influencing the self-recovery of the air inlet valve plate, so that a pressing plate is not required to be additionally arranged; and because of the piston chamber internal space is fixed, if install the clamp plate additional and can lead to the gas clearance volume increase, the gas output reduces.
The piston moves upwards, and the internal pressure of the piston chamber is increased; when the pressure of the piston chamber is greater than the pressure in the air outlet cavity of the top cylinder cover, the air outlet valve sheet is opened, and the air in the piston chamber flows out of the air outlet cavity of the top cylinder cover; because the pressure of the compressed gas in the piston chamber is too high, if the exhaust structure is not provided with a pressure plate, the gas outlet valve plate is easy to restore and lose efficacy, so that the sealing cannot be realized, and the failure is caused; therefore, a dummy pressing plate is required.
The mounting positions of the air inlet valve plate and the air outlet valve plate are opposite up and down, the automatic air inlet and outlet function can be realized, the structure is simple and convenient, the disassembly is easy, and the cost is low; the air inlet valve plate and the air outlet valve plate are of fan-shaped structures, so that impact resistance and deformation resistance can be effectively realized, the failure rate is reduced, and the service life is prolonged.
