Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
The embodiment of the utility model provides a: in the working process of the oxygenerator compression valve, the valve plate can impact the valve seat, so that vibration is caused, and noise is generated. In the noise control of the air inlet and exhaust of the compression valve of the oxygen generator, the noise generation link can be started, and the effective control of the noise can be realized by reducing the speed and the strength of the valve plate impacting the valve seat. The optimal design of the air valve can be realized by reducing the impact speed of the valve plate on the valve plate, destroying the impedance matching between the valve plate and the valve seat, optimizing the shape of the valve port, increasing the damping of a valve plate spring and the like. In the optimization design of the air valve, careful mathematical modeling and calculation are required, so that the whole working structure is optimized, the working efficiency of the compression pump is improved, and the noise is reduced. Based on this, my has proposed a compressor valve gap of making an uproar falls in oxygenerator, as shown in fig. 1-6, including the valve lid body 1, be provided with inlet port 2 and venthole 3 on the valve lid body 1, first foamed aluminum sheet 4, first steel sheet 5 and second steel sheet 6 have set gradually from top to bottom on the bottom surface of valve lid body 1, wherein first foamed aluminum sheet 4 length is greater than first steel sheet 5 length, first steel sheet 5 length is greater than second steel sheet 6 length, the afterbody of first foamed aluminum sheet 4, first steel sheet 5 and second steel sheet 6 aligns or draws close the setting, its head end stretches into in the valve lid body 1 behind first foamed aluminum sheet 4, first steel sheet 5 and the afterbody of second steel sheet 6 is passed to first double-screw bolt 7, first foamed aluminum sheet 4 head end covers inlet port 2.
The first foamed aluminum sheet 4 covers the air inlet hole 2, when air enters through the air inlet hole 2, the air entering air jacks the first foamed aluminum sheet 4, and overcomes the elasticity of the first steel sheet 5 and the second steel sheet 6, so that the first foamed aluminum sheet 4 is opened, and air entering is realized; when the gas is not passed through, the first foamed aluminum sheet 4 presses the gas inlet hole 2 again under the deformation resilience of the first steel sheet 5 and the second steel sheet 6.
Be provided with second foam aluminum sheet 8 on the top surface of valve bonnet body 1, its head end stretches into in the valve bonnet body 1 behind the tail end of second foam aluminum sheet 8 is passed to second double- screw bolt 9, and 8 head ends of second foam aluminum sheet cover venthole 3.
The second foamed aluminum sheet 8 covers the air outlet holes 3, and when air is exhausted through the air outlet holes 3, the second foamed aluminum sheet 8 is pushed open under the action of air pressure; when the gas does not pass through, the second foamed aluminum sheet 8 compresses the gas outlet 3 again under the action of the external atmospheric pressure, so that the gas is prevented from overflowing.
In the structure, consider that inlet port 2 and 3 pressure circumstances of venthole are different, to the inside highly compressed inlet port 2 of outside low pressure, the air current velocity of flow is very fast, make the quick vibration of valve block produce the noise easily, the valve block with air current direct contact adopts sound absorbing material foamed aluminum to make first foamed aluminum sheet 4, in order to prevent that air pressure is too big, the valve block can't stably seal admits air, 2, use the stack of multi-disc steel sheet, the upper strata uses first steel sheet 5 and second steel sheet 6 to guarantee that the resilience force is sufficient.
Considering the inside high pressure outside atmospheric pressure of venthole 3, the air current velocity of flow is slower, and air current pressure is less, so need not to adopt same structure with inlet port 2, only carry out the hole sealing with a slice second foamed aluminum sheet 8, when save material, make overall structure more rationalize.
On the basis of testing the maximum pressure difference value which can be generated inside and outside the air pump by using an experimental testing device, solidworks modeling can be utilized, simulation is carried out in fluent software, the manufacturing precision, the service life, the fatigue strength and the air inlet and outlet efficiency of production equipment are comprehensively considered, and the thickness and the length of the first foamed aluminum sheet 4, the first steel sheet 5, the second steel sheet 6 and the second foamed aluminum sheet 8 are finally determined.
