Embodiment 1

[0024] Such as figure 1 As shown, the figure schematically shows that the air supply mechanism of the reciprocating compressor includes an air supply valve structure 1 and a shut-off valve structure 2 .

[0025] In the embodiment of the present application, the air supplement valve structure 1 includes a valve plate 11 and an air supplement valve 12 arranged on the upper end of the cylinder body (not shown in the figure), wherein the valve plate 11 is in a spaced structure There is a pressure introduction hole 111 and an air supply hole 112 , and the air supply valve 12 is arranged in the air supply hole 112 . That is to say, the role of the air supply valve 12 is mainly to flexibly control the opening and closing of the air supply orifice 112 . However, it should be noted that since the structure and composition of the supplementary air valve 12 are well known to those skilled in the art, for the sake of space saving, no detailed description is given here.

Abstract

The invention relates to the technical field of energy-saving devices in the refrigeration low-temperature technology, and discloses a reciprocating type compressor air supplementing mechanism. The reciprocating type compressor air supplementing mechanism comprises a valve plate arranged at the upper end of a cylinder body, an air supplementing valve and a stop valve structure, wherein a pressureguiding hole and an air supplementing hole are formed in the valve plate at intervals, and the air supplementing valve is arranged in the air supplementing hole; and the stop valve structure comprisesan independent cavity formed in the upper end face of the valve plate, a supplementing air inlet is formed in the independent cavity, the stop valve structure further comprises a plugging part whichis arranged in the independent cavity and can divide the independent cavity into a back pressure cavity and an air suction pressure cavity, and a through hole is formed in the plugging part. The reciprocating type compressor air supplementing mechanism has the advantages that the supplementing air inlet is blocked in the air suction process, and meanwhile it is ensured that air supplementation isachieved when the pressure of an air cylinder is smaller than the air supplementing pressure.

Description

technical field [0001] The invention relates to the technical field of energy-saving devices in refrigeration and low-temperature technology, in particular to a reciprocating compressor air supply mechanism. Background technique [0002] Reciprocating compressors are widely used in medium and small refrigeration systems, such as cold storage or supermarket containers. With the promotion of air source heat pumps, reciprocating compressors are gradually used in medium-sized heat pump systems in alpine regions. In applications such as low-temperature cold storage and heat pumps in alpine regions, the evaporation temperature is extremely low. Correspondingly, the suction pressure and density of the compressor decrease accordingly, which leads to a decrease in the displacement of the compressor, an increase in the energy consumption of the system, and even compression The machine cannot work. Due to its excellent sealing performance, the efficiency of the reciprocating compress...
