This utility model discloses a nitrate treatment device with a flow regulation mechanism, relating to the field of chemical equipment technology. It includes a fixed pipe, an outlet pipe fixedly located at the middle of the outer side of the fixed pipe, an inlet bend fixedly located at the bottom end of the fixed pipe, a fixed seat fixedly located at the top end of the fixed pipe, and a mixing pipe fixedly located inside the fixed pipe. By configuring the fixed pipe, outlet pipe, inlet bend, and mixing pipe, when nitrate-containing wastewater passes through the mixing pipe, the wastewater pushes a piston upwards. The piston triggers a piezoelectric switch via a rod, causing the feed motor to rotate. The feed motor drives the movable sleeve to rotate, allowing the reducing agent in the storage chamber to be transported to the mixing pipe by the guide plate on the outside of the movable sleeve. The flow of nitrate-containing wastewater triggers the addition of the reducing agent, ensuring that the amount of reducing agent added is consistent with the amount of nitrate-containing wastewater discharged, thus achieving the effect of controlling the flow rate of the reducing agent.

The application relates to a display panel, a display module and a display device. The display panel comprises a color film substrate, an array substrate, a liquid crystal layer, a support assembly and a piezoelectric switch. The liquid crystal layer is arranged between the color film substrate and the array substrate. The support assembly comprises a spacer arranged in an array. The spacer has opposite first and second end faces in a direction perpendicular to the array substrate. The spacer is arranged on one side of the color film substrate close to the liquid crystal layer and in the liquid crystal layer through the first end face. The piezoelectric switch is arranged between the spacer and the array substrate. The piezoelectric switch comprises a piezoelectric layer, a first electrode and a second electrode. The second end face covers at least part of the piezoelectric layer in a perpendicular projection on the array substrate. The piezoelectric layer can conduct the first electrode and the second electrode to form a driving electric field. The scheme can directly adjust the angle of liquid crystal molecules during pressing and improve the display effect.

The utility model belongs to the technical field of piezoelectric switch equipment, and particularly relates to a motor for a circuit breaker. Comprising a shell, a transmission mechanism is arranged on the shell, a power mechanism is fixedly connected to the shell, the transmission mechanism is in transmission connection with the power mechanism, the transmission mechanism comprises a transmission shaft, the transmission shaft is rotationally connected to the shell, and a heat dissipation mechanism corresponding to an input shaft is arranged on the shell. The transmission mechanism is in transmission connection with a driving mechanism, and the driving mechanism is in driving connection with the microswitch. The situation that a large amount of heat is generated by the output shaft in a high-speed rotation state, so that the shell is deformed, and the microswitch cannot be normally triggered to work is greatly reduced.

The utility model relates to a dehumidification device for a steam blowout pipeline of a boiler, and relates to the technical field of steam boilers. The utility model relates to a dehumidification device for a steam blowout pipeline of a boiler. A first pipeline is communicated with a safety valve; the top of the liquid accumulation tank is communicated with the first pipeline, an outlet is formed in the bottom of the liquid accumulation tank, a valve body is arranged at the outlet, a piezoelectric switch is further arranged in the liquid accumulation tank, and the piezoelectric switch is electrically connected with the valve body; the liquid level sensor is a lever type liquid level meter rotationally installed in the liquid accumulation tank, when the height of the liquid level in the liquid accumulation tank reaches or exceeds a threshold value height, the liquid level sensor rotates till the piezoelectric switch is pressed, the piezoelectric switch generates an electric signal to control the valve body to be opened, and the threshold value height is lower than the height of the first pipeline. When condensate water in the liquid accumulation tank rises, the piezoelectric switch is pressed through rotation of the liquid level sensor, so that the valve body is controlled to be opened to complete automatic drainage work, and the risk that the safety valve is corroded by the condensate water is reduced.
