Description
Technical field
This utility model relates to spring technical field, particularly to a kind of air-conditioning freezing system electronic expansion valve spring assembly.
Background technology
Electric expansion valve is the refrigerant flow controlling to enter vaporizer by the degree of superheat controlling evaporator outlet gaseous refrigerant.Because belonging to electronic type shaping modes, therefore referred to as electric expansion valve.It has adapted to the demand for development that refrigeration machine is electrical integrated, has the good characteristic that heating power expansion valve is incomparable, and the intelligentized control method for intelligence system provides condition, is a kind of rising auto-control energy-saving element.
But in electric expansion valve, the anglec of rotation of limit spring is difficult to control in traditional air-conditioning refrigeration system, thus guide rail spring and limit spring degree of regulation are the highest, guide rail spring inside diameter, guide rail spring pitch, line footpath and limit spring internal diameter, line footpath are designed not reasonable, the sealing causing spring assembly is poor, or use alloy material to substitute spring assembly, but alloy material is perishable, elastic not, and then have impact on the overall quality of electric expansion valve.
Utility model content
In order to overcome the shortcoming of prior art, this utility model provides air-conditioning freezing system electronic expansion valve spring assembly, has done perfect from guide rail spring and the internal diameter of limit spring, pitch, height etc., has improved the performance of spring assembly.
Technical solutions of the utility model are as follows:
Air-conditioning freezing system electronic expansion valve spring assembly, including guide rail spring and limit spring, described guide rail spring includes extension, spire and lower extension, the number of turns of described limit spring is a circle, described limit spring two ends are provided with tentacle one and tentacle two, described limit spring is nested in the periphery of guide rail spring, described limit spring rises or falls with guide rail spring for guide rail spiral rotating, the internal diameter D2 of the described limit spring internal diameter D1 more than guide rail spring and the outer diameter D 0 less than guide rail spring.
As preferably, the length ratio between the upper extension of described guide rail spring, spire and lower extension three is 5:4:2.
As preferably, pitch t1 of described guide rail spring is 2 ± 0.02mm, and the uniformity of described pitch t1 is less than 0.05.
As preferably, the line footpath d1 of described guide rail spring is 0.8 ± 0.02mm, and the line footpath d2 of described limit spring is 1 ± 0.02mm.
As preferably, the tentacle one of described limit spring and the angle of tentacle two are 90 ° ± 1 °.
As preferably, the internal diameter D2 of described limit spring is 0.1mm ± 0.05mm with the internal diameter D1 difference of guide rail spring.
As preferably, described guide rail spring and limit spring are made up of stainless steel.
This utility model has the beneficial effects that: within the internal diameter D2 of limit spring 1) is limited in the internal diameter D1 more than guide rail spring and the outer diameter D 0 less than guide rail spring, decreases friction between the two, the beneficially limit spring rotation regulation along guide rail spring；2) proportionate relationship between extension on guide rail spring, spire and lower extension three is determined, when guide rail spring bearing up-down force, it is ensured that its type variable is in controlled range；3) optimize pitch line footpath and the uniformity of spring, improve the sealing of spring assembly；4) tentacle one of limit spring and the angle of tentacle two being designed as 90 ° ± 1 °, facilitate the control of the spring anglec of rotation, operation is convenient；(5) spring is made up of stainless steel, improves its decay resistance.
