Description

The energy-conservation air valve of compressor

Technical field

The utility model relates to a kind of compressor valve.

Background technique

Existing compressor valve mostly is used for chemical fertilizer industry, metallurgical industry, petroleum production, oil refining, petrochemical industry and refrigeration and other industry, the total power consumption of chemical industry piston compressor of China's use now reaches 30,000,000,000 kilowatt hours, the whole nation is annual because the chemical fertilizer power consumption of compressor is excessive, and the electric energy of loss is about 3,000,000,000 kilowatt hours.

Compressor valve is the key components and parts of piston compressor, is again fragile part, and energy consumption of compressor is had the greatest impact.Compressor valve comprises Aspirating valves and outlet valve, they are key members of the air-breathing and exhaust of control compresser cylinder, at present, similar Design is all taked in the compressor air suction valve of countries in the world and the design of outlet valve, as depicted in figs. 1 and 2, be that traditional Aspirating valves valve seat 3a and traditional outlet valve valve seat 1a are basic identical, traditional Aspirating valves lift limiter 4a and traditional exhaust valve lift limiter 2a are basic identical.Thisly continued to use nearly centenary design, people go back this design as the design model now, it is simple to get the structure manufacturing although it is so, but make the compressor air suction ability be subjected to unnecessary restriction, the gettering ability of piston compressor can not effectively be brought into play, in fact, the restriction gettering ability reaches about 10%.The compressor of countries in the world production is now also using this design.Can increase inflate quantity so how to be compressor, can save electric energy again and be very important.

Air valve is the critical component in the piston compressor, its work quality affect the air displacement of compressor and power consumpiton with and operational reliability, especially the length in air valve life-span also directly affects the working efficiency of piston compressor long-term operation, yet, owing to will inevitably cause the fault of air valve and shortening of air valve life-span in mechanically stressed and the movement process, therefore, for its necessary researching value is just arranged the working life of how to improve the piston compressor air valve.

Because the needs of aspects such as piston compressor structure, manufacturing, assembling, running, certain space or gap are left in some position in the cylinder, compressor in exhaust at the end, piston can not all be discharged pressurized gas, inevitable remaining sub-fraction pressurized gas are called clearance volume with this part pressurized gas occupied volume of cylinder under this state in the cylinder.Compressor a circuit exhaust at the end still has the pressurized gas of failing to discharge owing in the clearance volume, so the existence of clearance volume has directly reduced the air displacement of compressor.Clearance volume is influential to the throughput and the efficient of compressor, and clearance volume is crossed throughput and the decrease in efficiency that conference makes compressor.Therefore, under the prerequisite that guarantees the compressor safe operation, clearance volume should be as much as possible little, and therefore, it is imperative reducing clearance volume.

The model utility content

Technical problem to be solved in the utility model provides and a kind ofly can improve the compressor valve life-span, can save electric energy again, reduces clearance volume and increase the energy-conservation air valve of compressor of inflate quantity.

For solving the problems of the technologies described above, the technical solution of the utility model is: the energy-conservation air valve of compressor, comprise Aspirating valves and outlet valve, described Aspirating valves comprises Aspirating valves valve seat, Aspirating valves valve block and Aspirating valves lift limiter, and described Aspirating valves valve seat is fixedlyed connected with described Aspirating valves lift limiter; Described outlet valve comprises outlet valve valve seat, outlet valve valve block and exhaust valve lift limiter, and described outlet valve valve seat is fixedlyed connected with described exhaust valve lift limiter; The thickness of described outlet valve valve seat is the 50%-80% of described Aspirating valves valve seat thickness, and the thickness of described exhaust valve lift limiter is the 120%-200% of the thickness of described Aspirating valves lift limiter.

Owing to adopted technique scheme, the energy-conservation air valve of compressor, comprise Aspirating valves and outlet valve, described Aspirating valves comprises Aspirating valves valve seat, Aspirating valves valve block and Aspirating valves lift limiter, and described Aspirating valves valve seat is connected with fixed with described Aspirating valves lift limiter; Described outlet valve comprises outlet valve valve seat, outlet valve valve block and exhaust valve lift limiter, and described outlet valve valve seat is fixedlyed connected with described exhaust valve lift limiter; The thickness of described outlet valve valve seat is the 50%-80% of described Aspirating valves valve seat thickness, and the thickness of described exhaust valve lift limiter is the 120%-200% of the thickness of described Aspirating valves lift limiter; The utility model is taked the Aspirating valves valve seat thickeied and the outlet valve valve seat of attenuate, and the Aspirating valves lift limiter exhaust valve lift limiter and attenuate of thickening makes the clearance volume of compressor valve reduce nearly 50%; And strengthened the air valve rigidity, reduced gas leakage, prolonged the optimum operating condition time of air valve; Can make the compressor ability of inflating improve about 10%, energy-conservation about 10%.
