Description
Technical field
A kind of choke valve is the utility model is related to, especially a kind of new and effective vibration suppression noise reduction H type expansion valves.
Background technology
Expansion valve is an important component in refrigeration system, is generally mounted between liquid storage cylinder and evaporator, expansion valve makes
The liquid refrigerant of medium temperature high pressure connects throttling into the damp steam of low-pressure low-temperature, and heat is absorbed into evaporator to reach refrigeration
Effect, expansion valve can prevent evaporator area underutilization by the overheat of evaporator end come the flow of control valve
Or the phenomenon of frosting.
If expansion valve structure design is bad, it can operationally vibrate, the main source of vibration is medium temperature high pressure
Refrigerant directly impacts the elongated push rod of valve element, causes push rod to be impacted, and resets, then impacts, then resets, iterative cycles, by
Higher in frequency repeatedly, so as to produce dither and noise, this vibration directly affects the stable of expansion valve, if
It is close with the vibration frequency of compressor, covibration can be more caused, aggravates the vibration of expansion valve, serious will directly damage
Expansion valve, and huge noise is produced in operation.
For the vibrationproof of expansion valve, common practice is to install damping means on the push rod of expansion valve on the market, such as specially
A kind of heating power expansion valve of sharp application number 200610052369.2, the expansion valve install damping means in its big footpath vertical hole, so
And the longitudinal hole that push rod is installed on some expansion valves is smaller, without unnecessary space mounting damping means, it is impossible to make vibration damping portion
Part is arranged in the middle part of valve body, in order to adapt to the expansion valve of this structure, it is necessary to damping means are arranged on other rational positions,
So as to realize to the effect of the vibration and noise reducing of push rod.
