Solution to expansion valve

    Expansion valve is an important component of the refrigerating system, usually mounted between the solution containing tube and the evaporator. Expansion valve enables the refrigerant solution to be at average temperature and high pressure through throttling in low temperature low pressure wet vapor, then the refrigerant sucks the heat quantity in the evaporator for achieving refrigeration efficiency, expansion valve changes to control the valve flow in case of overheat at the end of the evaporator, avoiding the phenomenon of inadequate use of the evaporator area and collision.
