Specific embodiment
Specific introduction is done to the utility model with reference to the accompanying drawings and examples.
As shown in Figs. 1-3: the present embodiment is the suction type sand sprayer with high stationarity, including shell 1, in shell 1
T font mounting groove is provided at top center straight down, T font inner cover 2 and described is provided in T font mounting groove
Inner cover 2 is bolted with shell 1, and the inside of inner cover 2 is formed with sandblasting passage 21, is connected with top inside the shell 1 of 2 top of inner cover
Lid 3 is provided with annular groove on the shell 1 of the top of top cover 3, check ring 31, the top of shell 1 is provided in annular groove
There are three sand inlets 4 for setting, and the accommodating space that three sand inlets 4 are formed between shell 1 and inner cover 2 respectively is connected to, in shell
The bottom level of body 1 is provided with the mounting hole being connected to T font mounting groove, is provided with jet pipe 5 in mounting hole, and jet pipe 5
Interior conduit middle position forms narrowed structure, and plug 6,6 inside shape of plug are provided in the mounting hole of wherein one end of jet pipe 5
At there is terraced aisle, the small open at one end of terraced aisle is connected to the interior conduit of jet pipe, the big opening one of terraced aisle
