Embodiment
As depicted in figs. 1 and 2, a kind of injection apparatus for vapour compression machine fluid infusion, connect including snap joint 11, conversion
12, liquid-spraying rod 13, attaching nut 14, super gasket 15, spring 16, connecting seat 17, atomizer 18, the installation of injection apparatus
Process is：Connecting seat 17 is fixed on jet chimney 2 by welding or taper thread form；Spring 16 is put into connecting seat 17
In step inner chamber, super gasket 15 is arranged in the step male half coupling of connecting seat 17 end face；Atomizer 18 is passed through to bore spiral shell
Stricture of vagina installs the tail end of liquid-spraying rod 13, and carries out the corresponding water pressure test it is ensured that taper thread junction is not revealed；By attaching nut 14
Loaded by liquid-spraying rod 13 top, liquid-spraying rod 13 is inserted in connecting seat 17, coordinate, tighten with the screw thread of connecting seat 17, this
When super gasket 15 and spring 16 be in impaction state；Snap joint 11 is welded on adapter 12, will turn after welding
Changing-over 12 inside tapered thread end is connected with the outer cone thread at liquid-spraying rod 13 top, and is tightened by six square toes designing thereon；From
This completes injection apparatus 1 assembling of itself.
As shown in figures 1 and 3, this injection apparatus 1 arranges that process in systems is as follows：Injection apparatus 1 install in itself
Cheng Hou, has been fixed on jet chimney 2；Control section valve 3 is connected by way of snap joint 11 is with quick clamping；Control valve
3 other ends equally connect feed liquid pipeline 4 in the way of quick clamping, and feed liquid pipeline 4 can be arranged as required to corresponding flow
The components and parts such as meter, pressure-regulating valve.
As shown in figures 1 and 3, the work process of this injection apparatus is as follows：The liquid medium of certain pressure is by feed liquid pipeline 4
After entering control valve 3, it is flowed into injection apparatus 1, the atomized liquid spraying through injection apparatus 1 enters in jet chimney 2, and
With steam in pipeline, after mixing, gas is compressed by vapour compression machine 5, the saturated vapor after being heated up.
The regulation process of injection apparatus is as follows：The regulation of the atomized liquid that injection apparatus 1 spray mainly has two ways：One
Can be by changing hydrojet form and the liquid grain size that nozzle type obtains needs, the mouth spray on atomizer 18 is typically full
The hydrojet demand of sufficient certain angle, as shown in figure 3, atomizer 18 is changed to oblique shower nozzle by vertical shower nozzle so that it may so that spray
Liquid zone domain is changed into region a from region b；Two is to adjust hydrojet angle by rotating liquid-spraying rod 13, as shown in figure 3, adjusting hydrojet
The setting angle of bar 13, so that it may so that hydrojet region is changed into region c from region a, specific way is to unclamp attaching nut 14, sprays
Liquid bar can at once eject and unclamp under action from the spring 14, now rotates liquid-spraying rod 13 to needing position, more slowly tightens connection
Nut, just obtains the hydrojet angle of needs, can easily realize being directed towards still dorsad suction port of compressor injection.
Above the embodiment of invention is explained in detail, but the invention is not restricted to described embodiment.For
For those skilled in the art, in the case of without departing from the principle of the invention and spirit, these embodiments are carried out multiple
Change, modification, replacement and modification, still fall within protection scope of the present invention.
