Specific embodiment
Technical solution of the present invention is described in detail below in conjunction with attached drawing, in order to the understanding and reality of the present invention program
It applies.
Embodiment
As depicted in figs. 1 and 2, a kind of injection apparatus for vapour compression machine fluid infusion, including quick coupling 11, conversion connect
First 12, liquid-spraying rod 13, attaching nut 14, super gasket 15, spring 16, attachment base 17, atomizer 18, the installation of injection apparatus
Process are as follows: be fixed on attachment base 17 on jet chimney 2 by welding or taper thread form；Spring 16 is put into attachment base 17
In step inner cavity, super gasket 15 is mounted in the step male half coupling of 17 end face of attachment base；Atomizer 18 is passed through into cone spiral shell
Line installs the tail end of liquid-spraying rod 13, and carries out the corresponding water pressure test, guarantees that taper thread junction is not revealed；By attaching nut 14
By being packed at the top of liquid-spraying rod 13, liquid-spraying rod 13 is inserted into attachment base 17, with being threadedly engaged of attachment base 17, tighten, this
When super gasket 15 and spring 16 be in impaction state；Quick coupling 11 is welded on crossover sub 12, will be turned after welding
12 inside tapered thread end of changing-over head is connect with the outer cone thread at 13 top of liquid-spraying rod, and six square toes by designing thereon are tightened；From
This completes the assembling of injection apparatus 1 itself.
As shown in figures 1 and 3, the process of the injection apparatus 1 arrangement in systems is as follows: injection apparatus 1 installs in itself
Cheng Hou has been fixed on jet chimney 2；Control section valve 3 is connected in a manner of being quickly clamped quick coupling 11；Control valve
3 other ends equally connect feed liquid pipeline 4 in a manner of being quickly clamped, and corresponding flow can be set as needed on feed liquid pipeline 4
The components such as meter, pressure-regulating valve.
As shown in figures 1 and 3, the course of work of the injection apparatus is as follows: the liquid medium of certain pressure is by feed liquid pipeline 4
