the device comprises a main valve 1, a needle valve 2, a container 3, an electromagnetic valve 4, an ultrasonic controller 5, an ultrasonic probe 6, a valve rod 11, a main valve inlet end 12, a main valve outlet end 13, a main valve upper cavity control chamber 14, a float valve 7 and a display screen 51.

Detailed Description

As shown in fig. 1 and 2, the ultrasonic liquid level control valve system includes a main valve 1, a needle valve 2, a container 3 to be detected for liquid level, a solenoid valve 4, an ultrasonic controller 5 and an ultrasonic probe 6, wherein the main valve 1 includes a valve stem 11, a main valve inlet end 12, a main valve outlet end 13 and a main valve upper chamber control chamber 14, the main valve outlet end 13 of the main valve 1 is connected with the container 14 through a pipeline, the needle valve 2 is connected between the main valve inlet end 12 and the main valve upper chamber control chamber 14 through a pipeline, the solenoid valve 4 is connected with the main valve upper chamber control chamber 14 through a pipeline, the solenoid valve 4 is further connected with the ultrasonic controller 5 through a circuit, the ultrasonic controller 5 is electrically connected in series with the ultrasonic probe 6, the ultrasonic probe 6 is installed above the container 3. The electromagnetic valve 4 is also connected with a float valve 7 through a pipeline, and the float valve 7 is arranged in the container 3. When water is supplied to the main valve inlet 12, the needle valve 2, the solenoid valve 4 and the float valve 7 are normally open, so that water passing through the needle valve 2 enters the main valve upper chamber control chamber 14, and then flows into the container 3 through the solenoid valve 4 and the float valve 7, and pressure cannot be built up in the main valve upper chamber control chamber 14, and the inlet pressure entering the main valve inlet 12 opens the main valve 1, and a large amount of water is supplied into the container 3 through the main valve outlet 13. When the water level in the container 3 gradually rises to reach the highest set water level, the ultrasonic probe 6 sends a signal, the electromagnetic valve 4 is closed through the ultrasonic controller 5, and the water in the main valve upper chamber control chamber 14 gradually increases the pressure until the main valve 1 is closed. When the water level of the container 3 is gradually reduced and the ultrasonic probe 6 detects that the water level is lower than the set low water level, a signal is sent to cut off the power of the electromagnetic valve 4 and automatically open the electromagnetic valve, and the main valve 1 is also opened to supply water into the container 3. If power failure occurs, the electromagnetic valve 4 can be automatically opened after power failure, and the ball float valve can open or close the main valve to keep normal water supply. The liquid level is controlled by the ultrasonic measurement and control technology of the ultrasonic controller 5 and the ultrasonic probe 6, the liquid level range of the container 3 can be accurately controlled, and the control range can be set arbitrarily according to the requirements of users.

The detection central axis of the ultrasonic probe 6 is perpendicular to the liquid level to be detected in the container 3, the detection range of the ultrasonic probe 6 is generally fan-shaped, and the central axis of the fan-shaped is the detection central axis.

The ultrasonic probe 6 has a detection blind area, and the distance between the ultrasonic probe 6 and the highest liquid level of the container 3 is larger than or equal to the detection blind area of the ultrasonic probe, so that the influence of the detection blind area on the precision is avoided.

The ultrasonic controller 5 needs to be powered on, and the ultrasonic controller 5 is provided with a display screen 51 which can digitally display or calculate the height of the liquid level and check the height of the liquid level in real time.
