The invention provides a device for converting a space directional flow direction into a balanced flow, which has the characteristics of exquisite structure, strong direction adaptability and simple structure and realizes the conversion of a high-speed gas incoming flow from a non-balanced state to a balanced state.
As shown in fig. 1, the apparatus includes: the flow plug comprises a circular truncated cone structure 1, a first circular baffle piece 2, a flow plug 3, a shell 4 and a second circular baffle piece 8; the end part of one end of the shell 4 is provided with a circular truncated cone structure 1, the end part of the circular truncated cone structure 1 is additionally provided with a sampling hole 5, a first circular baffle piece 2 extends from the end part close to the circular truncated cone structure 1, 3 circular grooves 6 are additionally arranged between the first circular baffle piece 2 and the circular truncated cone structure 1, and a flow plug 3 is arranged in the circular truncated cone structure 1; towards the side away from the flow plug 3, a sampling chamber 7 is arranged in the shell 4, and the high-speed gas inflow is stored in the sampling chamber 7; the other end of the housing 4 extends outward with a second circular baffle 8.
In the present embodiment, the housing 4 has a hollow cylindrical structure.
The diameter of the upper end of the round platform structure 1 is smaller than that of the lower end thereof, so that the cross section of the round platform structure is in a trapezoidal structure. In this embodiment, the diameter of one end of the truncated cone structure 1 at the port of the housing 4 is smaller than the diameter of the opposite end thereof, preventing the high-speed gas entering through the sampling hole 5 from flowing out, ensuring that it is stored entirely in the sampling chamber 7.
The diameter of the sampling hole 5 is phi 1-30 mm. In the present example, the sampling hole 5 has a diameter of 1 mm.
The sampling chamber 7 has a diameter of phi 3-100 mm. In the present example, the sampling chamber 7 has a diameter of 30 mm.
The flow plug 3 is in a flat plate shape, a conical shape or an arc disc structure, and blocks and collides the gas flowing from the high-speed gas. In this embodiment, the flow stopper 3 has an arc-shaped disk structure.
The first circular baffle plate 2 is positioned above the second circular baffle plate 8, and the diameter of the first circular baffle plate is smaller than that of the second circular baffle plate.

When the directional high-speed gas inflow enters the interior through the sampling hole 5 on the circular truncated cone structure 1, gas molecules in the gas inflow collide with the flow plug 3, the collided gas molecules are reflected to the inner wall of the circular truncated cone structure 1 and the inner wall of the circular groove 6, and finally enter the interior of the sampling chamber 7, so that the gas distribution in the interior of the sampling chamber 7 accords with Maxwell distribution, namely the temperature, the speed and the density of the gas are balanced in all directions, and the purpose of converting the non-equilibrium high-speed gas inflow into the equilibrium gas inflow is achieved.
