The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure: a kind of pneumatic coolant charging machine that vacuumizes, it includes housing 1 and pneumatic vacuum pump pellet 2 and joint, wherein, described housing is by fore shell 1a, back cover 1b is formed by connecting, fore shell 1a has accounted for substantially in the examples of implementation, back cover 1b becomes an outer plate body, they are to altogether, be screwed and connected and composed housing 1, and formed a moderate cavity in housing 1 inside, make pneumatic vacuum pump pellet 2 be installed in fore shell 1a, in the cavity between the back cover 1b, formed main body 100, make main body 100 be provided with the fluidic channel 3 that forms jet, main body 2 one sides are provided with first interface 2.1 that connects high pressure draught, main body opposite side position is provided with exhaust outlet 2.8, and, on same horizontal plane, main body 100 also is provided with parallel bleed-off passage 4 in addition, the inner end of bleed-off passage 4 is communicated with fluidic channel 3 by aperture, tube connector 5 is threaded between housing 1 and the pellet 2, improved sealing property and connectivity robustness, tube connector 5 is exposed at an end in the main body outside just as second interface 2.2, the joint of oneself in the connection.Main body 1 top is provided with and has connected low-pressure meter 6 and high pressure gauge 7, low-pressure meter 6 is communicated with the 4th interface 2.4 by valve, whether control handle 8 controls with first valve are communicated with, and high pressure gauge 7 is communicated with the 5th interface 2.5 by valve, whether are communicated with 9 controls of the second valve control handle.Be connected with the adapter of belt lacing at third and fourth, on five, six interfaces, wherein the 3rd interface 2.3 and the 4th interface 2.4 are communicated with by valve, and the 5th interface 2.5 and the 6th interface 2.6 also are communicated with by valve.Main body 100 is provided with the annotate refrigerant passage 10 of refrigerant of parallel being used for and connects the 4th interface 2.4 and the 6th interfaces 2.6 above bleed-off passage and fluidic channel.Main body 100 is provided with the observation window 2.7 that is communicated with refrigerant passage 10 at the top.
