Description
Technical field
The present invention relates to compressor suction air valve, refer in particular to anti-hammering of liquid compressor air gate.
Background technique
Air valve is the vitals of reciprocal compressor, the quality of air valve work is directly connected to the Economy and the reliability of compressor operation, it is little that the basic fundamental of compressor valve is required to be that gas stream is crossed the drag losses of air valve, air valve will be grown working life, the clearance volume that air valve forms is little, has good sealing when air valve is closed.Using air valve at present mainly is to adopt tongue type valve block single-point location, and tongue type valve block is pressed on the exhaust port, and the rising snubber also is the tongue type, has just lifted a level altitude, and tongue type valve block is screwed with rising snubber both is in the same place.Compressor runs up and can reach per second and open and close 24 times (1440 rev/mins) and make valve block bear the high-frequency percussion load when work, so present this valve block single-point location is easy to damage.Owing to the car air conditioner specific factor, be easy to produce the liquid hammer valve block and cause a sheet to damage simultaneously.
Summary of the invention
The objective of the invention is to be improved, innovate, a kind of reliable performance is provided, the anti-hammering of liquid compressor air gate that operational effect is stable at shortcoming that exists in the background technique and problem.
Technical solution of the present invention is: construct a kind of compressor valve of being made up of valve plate, suction port, exhaust port, be characterized in: suction port on the described valve plate and exhaust port are respectively established three, correspondence is arranged as one group, and the suction port on the valve plate and exhaust port are provided with two groups of symmetric arrays; Suction port is provided with the suction valve chip group, is used to cover gas unidirectional is flowed; Exhaust port is provided with the exhaust valve plate group, is used to cover discharge after making gas compression on the exhaust port; Exhaust valve plate in the described exhaust valve plate group is the fillet rhombus; Rising snubber in the described exhaust valve plate group is the fillet rhombus, covers on the exhaust valve plate by spring, and is fixed on the valve plate by bolt and spring three points location; Described exhaust valve plate group covers a plurality of exhaust ports simultaneously.
The present invention has following advantage and effect:
1, compressor valve is the positive displacement compressor vitals, is inhaled into or discharges with making gas unidirectional, and can prevent to flow backwards.Divide Aspirating valves machine outlet valve to use in the cylinder of compressor for two kinds in turn to compress, the control mechanism of exhaust, expansion and air-breathing four processes, the quality of its performance directly determines the displacement of compressor.
2, owing to present valve board structure, extraction flow is low to cause the higher intensity of valve block that makes easily of delivery temperature to change, and makes valve plate damage.The present invention increases gas flow orifice makes, and degree of raising flow makes temperature reduce valve plates reliable and durable greatly.
3, the shape of valve block is also improved the place's perforate of suction valve chip suction port has increased throughput, and shape is insulted in the exhaust valve plate design, and extraction flow can be from different angle circulation non-resistances.
4, anti-liquid hammer design.Standard valve in the past can not resist liquid hammer, be easy to damage exhaust valve plate when running into liquid hammer, the present invention can overcome anti-liquid hammer spring force when running into strong liquid hammer, backs down the rising snubber automatically, can avoid incompressible liquid to damage parts such as cylinder, piston, valve plate, valve block like this.
