Problems solved by technology
It solves the problem that the current valve group adopts the structure of concave valve plate or thick steel plate, the processing technology is poor, the leakage rate of the valve group is high after assembly, and the clearance volume will increase at the same time, and the performance of the compressor will decrease.
[0005] Although the patent reduces the thickness of the valve plate to a certain extent, so as to achieve the purpose of reducing the clearance volume, but in actual use, due to the reduced thickness of the valve plate, its strength is weakened, resulting in the exhaust valve plate or suction The valve plate will drive the valve plate to deform during the reciprocating motion, which will affect its use effect, and because the valve plate needs to limit the lift limiter, this makes the thickness of the valve plate not easy to be too small, and the thickness of the valve plate Reduction is limited

Abstract
The invention relates to a valve bank part of a low loss compressor. Thickness of a valve plate is reduced to 0.3-0.5 mm, and an air suction valve block and an exhaust valve block are separately fixedto the valve plate. By arranging an enhancing plate additionally, strength of the valve plate is enhanced. Meanwhile, by matching a lift limiter designed in a simplified structure, the lift limiter can be controlled effectively by forming a positioning through hole in the enhancing plate, so that positioning and mounting of the lift limiter are guaranteed while thickness of the valve plate is ensured to be reduced. The mounting sealing property of the valve bank part is guaranteed, so that the efficiency of the compressor is improved.
Description
technical field [0001] The invention relates to the technical field of compressor components, and more specifically, to a valve group component of a low-loss compressor and the compressor. Background technique [0002] The reciprocating piston refrigeration compressor drives the crank connecting rod mechanism to push the piston to reciprocate through the operation of the motor during work. The suction and exhaust valves in the valve group are intermittently opened and closed under the action of the piston, and the refrigerant is continuously sucked and discharged. Thereby cooling is achieved. Among various factors affecting compressor efficiency, volumetric efficiency is a very important one. Among the factors that determine the volumetric efficiency of the compressor, the clearance volume, that is, the residual volume formed between the end of the piston and the valve plate after the piston reaches the top dead center, is very important. The smaller the clearance volume, ...
