Implementation

Referring to the drawings, the utility model provides a gravity-type constant outflow mechanism, which includes a liquid storage tank 1 and a constant level water tank 7. Both the liquid storage tank 1 and the constant level water tank 7 are top-opening containers. The liquid storage tank 1 passes through the bottom. The water pipe 2 is connected to the upper part of the constant water tank 7. The water pipe 2 is successively provided with a gate valve 3, a Y-type filter 4, a solenoid valve 5 and a float valve 6. The float valve 6 is set inside the constant water tank 7 and can be adjusted by adjusting the float valve. 6 height to adjust the designed constant water level in the constant level water tank 7. The bottom of the constant level water tank 7 is provided with an outlet pipe 8, and the top is provided with an overflow pipe 10. The outlet pipe 8 is provided with a regulating valve 9, and the constant level water tank 7 is provided with a liquid level inside. Position meter 11, the diameter of water pipe 2 is larger than the diameter of water outlet pipe 8.

When used, the liquid storage tank 1 stores a certain amount of water or liquid medicine. The water level in the liquid storage tank 1 is higher than the water level in the constant water tank 7, and there is a sufficient liquid level difference. The liquid in the liquid storage tank 1 passes through the liquid storage tank. 1. The water pipe 2 at the bottom flows into the constant level water tank 7 under the action of gravity. The float valve on the water outlet pipe is in the constant level water tank 7. When the water level in the constant level water tank 7 is lower than the designed constant water level, the float valve is open. state, the liquid in the liquid storage tank 1 will continue to flow into the constant level water tank 7. At this time, the water level in the constant level water tank 7 will continue to rise until the designed constant water level. In this process, the float in the float valve 6 will rise as the liquid level rises. , and continuously reduce the opening degree of the water passage of the float valve 6, thereby continuously reducing the water inflow flow of the constant water tank 7 until the float valve 6 is completely closed, the liquid storage tank 1 stops supplying water to the constant water tank 7, and the constant water tank 7 passes Water comes out of the bottom outlet pipe 8, and the required outlet flow can be achieved by adjusting the regulating valve 9. When the water level in the constant water tank 7 drops below the designed constant water level, the float ball in the float valve 6 will drop as the water level drops, causing As the opening degree of the water channel of the float valve 6 continues to increase, the inlet flow rate of the constant water tank 7 will continue to increase, and the liquid in the liquid storage tank 1 will continue to flow into the constant water tank 7 to the designed constant water level. This process will be repeated continuously, so that The water level in the constant level water tank 7 is maintained at a designed constant water level, so that the water pressure difference in the water outlet pipe 8 remains unchanged, and the water outlet from the water outlet pipe 8 maintains a continuous constant flow rate, thereby achieving the purpose of accurate water supply or dosing at a constant constant flow rate.

The principle of the float valve 6 is that the float valve 6 contains a float element, which can float on the water. The float is lowered or raised by the water level to control the opening and closing of the valve. It is a non-power type. Automatic opening and closing valve, which controls the water supply through liquid level and has flow regulation function. The float valve 6 can be a crank-arm float valve or an integrated float valve. The float valve 6 can be installed outside the constant-level water tank 7 and communicate with the liquid level in the constant-level water tank 7 through a pipeline. It can also be installed inside the constant-level water tank 7 , the float ball is in direct contact with the liquid, and the position of the float valve 6 can be adjusted up and down to adjust the designed constant water level in the constant level water tank 7 .

The water pipe 2 is provided with a Y-type filter 4 and a solenoid valve 5, and the constant level water tank 7 is provided with a liquid level gauge 11. The Y-type filter 4 can intercept impurities in the wastewater and avoid clogging of the water pipe 2 and accessories. Clean the Y-type filter 4 regularly by closing the gate valve 2, removing the filter components in the Y-type filter 4, cleaning them, and then installing them back, which is easy to disassemble. When the water level in the constant-level water tank 7 drops to the lowest warning level, the alarm is started to indicate a fault; when the water level in the constant-level water tank 7 rises to the highest warning level, the alarm is started to indicate a fault, and the electric valve 4 is automatically closed at the same time. The liquid storage tank 1 stops replenishing water to the constant level water tank 7; when the water level in the constant level water tank 7 rises to the overflow level, it will be discharged through the overflow pipe 10 to prevent the liquid from overflowing and polluting the environment.

The diameter of the water pipe 2 is larger than the diameter of the water outlet pipe 8, and the water inlet capacity of the constant level water tank 7 is greater than the water outlet capacity to ensure sufficient replenishment of water to achieve a constant water level.
