Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, a kind of Venturi tube convenient for adjusting, including tube body 10, one end of tube body 10 are connected with gas material
Mix efferent duct 2, and the port of gas material mixing efferent duct 2 is fixedly installed with outlet(discharge) flange 1, the other end of tube body 10 be provided with into
Tracheae 11, and the port of air inlet pipe 11 is fixedly installed with air inlet flange 8, the upper end of tube body 10 is provided with feed pipe 9, tube body 10
Be internally provided with gas-guide tube 4, and gas-guide tube 4 is connected with air inlet pipe 11, and the lower end surface of gas-guide tube 4 is provided with guide support column 5,
Gas-guide tube 4 is connected with outlet side conical pipe 3 far from one end of air inlet pipe 11, and air inlet pipe 11 and the junction of tube body 10 are provided with method
Blue gland 7, and packing item 6 is provided on flange gland 7；
