Thermostatic expansion valve's diaphragm chamber fills notes device

The utility model discloses a thermostatic expansion valve's diaphragm chamber fills notes device belongs to the thermostatic expansion valve throttle technical field among the vapour compression-type refrigerating system, is applicable to the notes that fill of various thermostatic expansion valve diaphragm chamber media. Mainly by base 1, bottom electrode 2, go up electrode 3, sealed " O " shape circle 4, sealed " O " shape circle 5, pressure sensor 6 etc. And constitute. Its characterized in that base 1 by base body 11, fill annotate medium pipeline 12, constant temperature pipeline 13 is constituteed. When the diaphragm chamber filled and annotates, the isothermal liquids that flow in the constant temperature pipeline 13 made base 1 be in the constant temperature state, have guaranteed to fill the uniformity of annotating medium refrigerant pressure, and pressure sensor 6 annotates medium pipeline 12 and is connected with filling, makes pressure sensor 6 show that 8 inside refrigerants of the accurate reflection diaphragm chamber body of pressure, inert gas fill notes pressure to the uniformity of annotating back diaphragm chamber rigidity is filled in the assurance, improves thermostatic expansion valve's adjusting function.
