Description
Technical field
The present invention relates to a kind of bellows filling device of heating power expansion valve, belong to the heating power expansion valve throttling technology field in vapor compression type refrigerating system, be applicable to filling of various thermostatic expansion valve bellows medium, be specially adapted to refrigerant, inert gas two kinds of media mix the bellows filled.
Background technology
Bellows is as the critical component in heating power expansion valve, and play a part to provide thermal expansion valve regulation power, the quality of its performance directly affects the performance of heating power expansion valve.
Existing bellows filling device as shown in Figure 1, primarily of base 1, bottom electrode 2, top electrode 3, sealing round section joint ring 4, seals the compositions such as round section joint ring 5.Bellows fills process: bellows sealing steel ball 6, bellows body 7 put into filling device, top electrode 3 declines, seal by compressing bellows body 7, form annular seal space 8, by filled mouth 11, vacuumize rear filled medium, bottom electrode 2 rises, bellows sealing steel ball 6, bellows body 7 are welded by stored energy welding, make filled medium-tight inner at bellows.Because refrigerant is a kind of medium very responsive to temperature, its pressure changes along with variations in temperature, and inert gas pressure does not change substantially to variations in temperature, with above-mentioned filling device carry out refrigerant, the mixing of inert gas two kinds of media fill time, due to the uncertainty of filling device temperature, cause first being filled with the inner refrigerant pressure of bellows inconsistent, change refrigerant, the component ratio of inert gas in bellows inside, thus make the rigidity of bellows occur inconsistent phenomenon, directly affect the adjusting function of heating power expansion valve.
Summary of the invention
The object of the bellows filling device of heating power expansion valve of the present invention is just to solve the problem and deficiency, a kind of novel bellows filling device is provided, its compact conformation, fills dependable performance, can be widely used in filling of various thermostatic expansion valve bellows medium.
Bellows filling device of the present invention, mainly comprises base, bottom electrode, top electrode, sealing round section joint ring, pressure sensor etc., it is characterized in that: described base is made up of base body, filled medium pipeline, Constant-temp. pipeline.
The present invention also comprises following additional technical feature:
Described base is made by the fine copper that thermal conductivity is splendid.
Described constant temperature Bottomhole pressure be isothermal liquid.
Described pressure sensor is connected with filled medium pipeline.
Described filled medium pipeline is arranged in the middle of Constant-temp. pipeline.
The present invention by arranging base body, filling medium pipeline, Constant-temp. pipeline on filling device base, and base is made by the fine copper that thermal conductivity is splendid, base is made to be in temperature constant state by the isothermal liquid flowed in Constant-temp. pipeline, ensure the stability filling medium refrigerant pressure, pressure sensor is connected with filled medium pipeline, pressure sensor is shown, and pressure accurately reflects the inner refrigerant of bellows, inert gas fills pressure, thus ensure the uniformity of bellows rigidity, improve the adjusting function of heating power expansion valve.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

Detailed description of the invention
As shown in Figure 2, the present invention is primarily of base 1, bottom electrode 2, top electrode 3, sealing round section joint ring 4, composition such as sealing round section joint ring 5, pressure sensor 6 etc.Described base 1 is made up of base body 11, filled medium pipeline 12, Constant-temp. pipeline 13, base 1 is made by the fine copper that thermal conductivity is splendid, in Constant-temp. pipeline 13, flowing is isothermal liquid, pressure sensor 6 is connected with filled medium pipeline 12, fills medium pipeline 12 and is arranged in the middle of Constant-temp. pipeline 13.
It is as follows that bellows fills process:
Opening device, in Constant-temp. pipeline 13, flowing isothermal liquid, makes base 1 be in temperature constant state, bellows sealing steel ball 7, bellows body 8 are put into filling device, top electrode 3 declines, and sealing, forming annular seal space 9 by compressing bellows body 8, after system vacuumizes, first be filled with coolant media, then be filled with inert gas medium, bottom electrode 2 rises, bellows sealing steel ball 7, bellows body 8 are welded by stored energy welding, make filled medium-tight inner at bellows.Because base 1 is in temperature constant state, ensure that the uniformity of filled medium refrigerant pressure, pressure sensor 6 is connected with filled medium pipeline 12, pressure sensor 6 is shown, and pressure accurately reflects the inner refrigerant of bellows body 8, inert gas fills pressure, thus ensure the uniformity filling rear bellows rigidity, improve the adjusting function of heating power expansion valve
