What is the way to overflow the port?

The overflow is located at a height of about 300 mm on the roof. When rainwater accumulates to a height of 300 mm on the roof, it is discharged from the overflow. Below 300 degrees, water still needs to be discharged through the downpipe.

Constant pressure overflow function: in the throttling regulation system of the quantitative pump, the quantitative pump provides constant flow. When the system pressure increases, the flow demand will decrease. At this time, the overflow valve is opened, so that the excess flow overflows back to the oil tank, ensuring the inlet pressure of the overflow valve, that is, the pump outlet pressure is constant (the valve port often opens with pressure fluctuation).

Common types of overflow pipes are as follows:

1. When a large container is filled with liquid, in order to avoid overflowing when the liquid is full or filling too much in a closed container, an overflow port is opened at the position where the container allows the maximum filling amount, and a pipe is connected to the mother liquid. This pipe is called an overflow pipe. It is very common in chemical equipment.

2. In daily life, the small hole in the middle and upper part of the sink is the overflow port.

3. The water pipe above the solar water storage tank is an overflow pipe.

There is a pipe from top to bottom on the side of the outer barrel of the washing machine, which is the overflow pipe. An overflow port is arranged at the maximum capacity position of the washing machine and connected with an overflow pipe. When the water level in the bucket is higher than the highest water level, it overflows through the overflow pipe to prevent flooding and electric shock.
