Exhaust limiting plate for improving energy efficiency of compressor, and compressor

Abstract

The invention relates to the technical field of compressors, in particular to an exhaust limiting plate for improving the energy efficiency of a compressor. The exhaust limiting plate for improving the energy efficiency of the compressor comprises a limiting plate body, wherein the periphery of the limiting plate body is matched with an installation groove in a valve plate; a lug boss for tightlypressing an exhaust valve plate is arranged at one end of the limiting plate body; a clamping part matched with the installation groove is arranged at the other end of the limiting plate body; the limiting plate body is provided with a liming surface in the direction from the lug boss to the clamping part; the exhaust valve plate is limited by the limiting surface when being opened to a maximum angle; a concave pit concaved locally is arranged at one end, far away from the lug boss, of the limiting surface; and the exhaust valve plate is firstly limited by the limiting surface when being opened to the maximum angle, then a tongue part of the exhaust valve plate continuously moves in the foundation pit, and the exhaust valve plate is finally rebounded and closed. According to the exhaust limiting plate for improving the energy efficiency of the compressor provided by the invention, the energy efficiency of the compressor is improved.

technical field [0001] The invention relates to the technical field of compressors, in particular to an exhaust limiting plate for improving energy efficiency of compressors. Background technique [0002] Piston compressors have suction and exhaust processes during operation. When exhausting, the exhaust valve plate is quickly flapped outward under the impact of high-pressure exhaust gas. To prevent excessive deformation of the valve plate, a lift limit device must be installed to limit The opening angle of the exhaust valve plate and the limit surface of the existing exhaust limit plate are all smooth curves. Although this structure operates reliably, the frequency of opening and closing of the exhaust valve plate is very high, and there will be noise when exhausting.

[0002] Piston compressors have suction and exhaust processes during operation. When exhausting, the exhaust valve plate is quickly flapped outward under the impact of high-pressure exhaust gas. To prevent excessive deformation of the valve plate, a lift limit device must be installed to limit The opening angle of the exhaust valve plate and the limit surface of the existing exhaust limit plate are all smooth curves. Although this structure operates reliably, the frequency of opening and closing of the exhaust valve plate is very high, and there will be noise when exhausting. Part of the residual air has not been discharged in time, and the exhaust valve has been closed, resulting in a reduction in exhaust volume and exhaust loss. When the exhaust valve is closed, it mainly depends on the resilience of the valve. When the exhaust valve is closed, the suction valve is closed. If the exhaust valve is not closed fast enough, the high-temperature exhaust will heat the low-temperature gas at the suction end, reducing the suction efficiency
