Problems solved by technology

In addition, the sealing material in the solenoid valve is basically rubber, and there is a problem that the rubber will age after being placed for a long time and cause the seal to fail.
In a special environment, such as a high electromagnetic radiation environment, the anti-interference ability of the solenoid valve is greatly weakened, or even fails.

Embodiment Construction

[0021] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] The inventive device such as figure 1 As shown, it includes a jet inlet 1, an inlet nozzle 2, a control port 3, a concave split splitter 4, an airflow deflection left outlet 6-1, and an airflow deflection right outlet 6-2. The airflow of jet inlet 1 is provided by a constant pressure air tank, and the flow rate of the inlet airflow is controlled by an airflow valve. The jet element is designed as a monostable wall-attached oscillating jet element. When there is no input to the control port 3, according to the Coanda effect, the airflow entering from the jet inlet 1 will always be attached to the side of the airflow deflection right outlet 6-2 port , the airflow flows out from the airflow deflection right outlet 6-2, such as figure 2 shown. When the control port 3 has an input, the airflow is deflected and attached to the port side of the left outlet 6-1 of...

Abstract

The invention discloses a frequency-controllable airflow deflection control device and belongs to the technical field of fluid control. The control device comprises a monostable wall-attached oscillating efflux element and a plasma exciter (5). The monostable wall-attached oscillating efflux element comprises an efflux inlet (1), an inlet nozzle (2), a concave flow distribution wedge (4), a control port (3), a left airflow deflection outlet (6-1) an a right airflow deflection outlet (6-2). The frequency-controllable airflow deflection control device has the advantages that the size is small, the structure is simple, continuous adjustment can be achieved, the service life is long, the deflection frequency is high, and the control energy needing to be input is low.

Description

technical field [0001] The invention relates to a frequency-controllable airflow deflection control device, which belongs to the technical field of fluid control. Background technique [0002] At present, the mechanical components controlling fluid automation in engineering applications include various forms of solenoid valves, which are used to adjust the direction, flow, speed and other parameters of the medium in industrial production, and the solenoid valves used for airflow deflection are called directional control valves. . The working principle of the existing solenoid valve is that there is a closed cavity inside the solenoid valve, and through holes are opened at different positions, and each hole is connected to a different pipeline. There is a piston in the middle of the cavity, and there are two electromagnets on both sides. When working, the valve body is attracted to the side of the energized electromagnet. In the directional control valve, the jet deflection...
