Compressor exhaust valve component element

Abstract

The compressor exhaust valve assembly is mainly composed of a valve housing and a slider. The valve casing is fixed on the end face of the cylinder of the compressor and communicated with the exhaust end of the compressor. There is a storage space for accommodating the slider inside, and the two ends are respectively provided with a discharge hole and a return hole and keep a certain distance; The block is accommodated in the housing space between the discharge end of the compressor and the discharge hole of the valve housing, and the discharge hole can be opened or closed due to the pressure difference between the discharge end of the compressor and the discharge chamber moving left and right in the housing space . The invention utilizes the sliding of the slider to control the discharge of the compressed gas, which can effectively reduce the airflow resistance and impact noise, and can effectively prevent the backflow of the discharge gas.

Description

1. Technical field [0001] The invention relates to a discharge valve assembly of a compressor, in particular to a compressor discharge valve assembly which is opened and closed in a sliding manner. 2. Background technology [0002] The compressor is a machine that uses a motor to drive a rotary motion or a linear motion to compress the gas. The cylinder is equipped with an exhaust valve to control the discharge of the compressed gas. figure 1 and figure 2 Schematic diagrams of reed exhaust valve and piston exhaust valve respectively. [0003] Such as figure 1 As shown, one end of the reed 1 of the reed exhaust valve is fixed on the cylinder 2, and its free end is opposite to the discharge port 2a and blocks the discharge port 2a. The outstanding defect of this kind of exhaust valve is that the loss is caused by the blocking of the reed 1 during exhaust; moreover, when the compression ratio increases, the opening and closing of the reed 1 will generate noise.

AI Technical Summary

Problems solved by technology

The outstanding defect of this kind of exhaust valve is that the loss is caused by the blocking of the reed 1 during exhaust; moreover, when the compression ratio increases, the opening and closing of the reed 1 will generate noise.

[0004] like figure 2 As shown, in the piston exhaust valve, the compressed gas must push the heavy piston 4 to the top of the valve housing 6 to be discharged, so the discharge resistance is quite large; especially in the process of high compression ratio operation, the piston 4 cannot Reliably prevents backflow of compressed gas, which would cause backflow losses

Moreover, during abnormal operation, the lifting and lowering of the piston 4 in the valve housing 6 will also generate impact noise
