Abstract
The utility model discloses an air valve of a reciprocating piston compressor, which comprises a valve seat, an opening and closing element, a lift limiter and an elastic element, wherein the elastic element is in a middle concave spiral spring, and the diameter of the rotating surfaces arranged at both ends of the elastic element is greater than the diameter of the rotating surface arranged in the middle of the elastic element. Because the elastic element provided by the air valve is the middle concave spiral spring, the characteristic line of the spring is in a gradual increase type, the rigidity of the spring is increased along the load increase, the force exerted on the opening and closing element by the elastic element when the air valve is completely closed is reduced favorably, in addition, the natural vibration frequency is also a variable, and the resonance and fluttering resistance performance is higher. Thereby, the elastic element of the air valve is changed from a cylindrical spiral spring into the middle concave threaded spring, the reliability of the elastic element can be improved favorably, further, the moving rule of the air valve can be optimized, the service life of the air valve is prolonged, and the energy consumption of the air valve is reduced.
Description
Technical field
The utility model relates to a kind of air valve of reciprocating-piston compressor, elastic element especially wherein.
Background technique
The air valve of reciprocating-piston compressor generally comprises valve seat, opens and closes element, elastic element and lift limiter, and elastic element is a most important part in the air valve, and its performance directly influences the working life and the energy loss of air valve.The characteristic of elastic element is mainly determined by its structure, desirable air valve elastic element should be to become rigidity, for example during the air valve full cut-off elastic element act on the power that opens and closes on the element should be less, during the air valve standard-sized sheet elastic element act on the power that opens and closes on the element should be bigger.But in the prior art, the elastic element of the air valve of reciprocating-piston compressor generally adopts cylindrically coiled spring, and the characteristic line of this spring is a straight line type, stiffness spring such as belongs to, this is unfavorable for the optimization of the air valve characteristics of motion, also can produce harmful effect to the working life and the energy loss of air valve.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of air valve of reciprocating-piston compressor, and the rigidity of the elastic element in this air valve can increase along with the increase of load.
For this reason, the air valve of the reciprocating-piston compressor that the utility model provides, comprise valve seat, open and close element, lift limiter and elastic element, elastic element is a hourglass shaped spring, and the diameter of the two ends surface of revolution of elastic element is greater than the diameter of surface of revolution in the middle of the elastic element.
Because the elastic element that the utility model provides is a hourglass shaped spring, the characteristic line of its spring is cumulative type, the rigidity of spring increases along with the increase of load, elastic element acts on the power that opens and closes on the element when helping reducing the air valve full cut-off, and its natural frequency of vibration also is a variate, anti-resonance, flutter ability are stronger, therefore the elastic element with air valve changes the reliability that middle concave screw thread spring helps improving elastic element into by cylindrical helical spring, and then the characteristics of motion of optimization air valve, improve the working life of air valve, reduce the energy consumption of air valve.
Description of drawings
The partial structurtes cross-sectional schematic of the air valve of the reciprocating-piston compressor that provides for the utility model among the figure.
Embodiment
