Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of Explanation, it is therefore an objective to help those skilled in the art to have more complete, accurate and deep reason to design of the invention, technical scheme Solution, and contribute to its implementation.
A kind of electric T-shaped valve as shown in Figure 1, including motor base 1, the motor base are provided with fixing hole for one Flat board, fixed support 2, adpting flange 4, the flange center are provided with through hole, valve element 3, and the valve element side wall is provided with two circular holes In the middle part of to cylinder, it is connected respectively with air inlet 51, gas outlet 52 or gas outlet 53, tee pipe coupling 5, the tee pipe coupling 5 Gas outlet 52 and gas outlet 53 on same pipeline, gas outlet 51 is perpendicular, and a sealing 6.
A kind of electric T-shaped valve as shown in Figure 1, the motor base 1 welds with the adpting flange 4, with fixed support 2 are connected by pin, to prevent vibration of the motor under unmanned plane bad working environments.
A kind of electric T-shaped valve as shown in Figure 1, the valve element 3 include stress hole 31 and 2 air admission holes 32, stress hole shape Shape is identical with motor rotation axis shape, and air inlet bore dia should be slightly larger than gas channel internal diameter.
