Plastic Balls Manufacturer introduces the working principle of the pump head:

First, manually push the pressure handle down, the volume in the spring cavity decreases, the pressure rises, and the liquid enters the nozzle cavity through the hole of the valve core.

Secondly, the liquid is sprayed out through the nozzle. When the pressure handle is released, the volume in the spring cavity increases, forming a negative pressure, and the sphere opens under the action of the negative pressure.

Finally, the liquid in the bottle enters the spring cavity. At this time, there is a certain amount of liquid in the valve body. When the handle is pressed again, the liquid stored in the valve body will rush upward and spray out through the nozzle.

Precautions for using the pump head:

1.The glass ball or steel ball under the spring. The seal here is very important. It is related to the strength of the liquid in the spring cavity. If there is leakage, part of the liquid will leak into the bottle when the pressure handle is pressed. And affect the effect of liquid spray.

2. It is the sealing ring at the upper end of the valve body. If there is leakage, the upward force of the liquid will be reduced when the pressure handle is released, resulting in a small amount of liquid stored in the valve body, which will also affect the spray effect.

3. The fit between the pressure handle and the valve core. If the fit here is loose and there is leakage, there will be a certain resistance when the liquid rushes up to the nozzle, and the liquid will flow back. If it leaks here, it will also affect the spray effect.

4. The design of the nozzle, design of the nozzle is directly related to the spray effect.

Through the above introduction,Steel Balls Wholesaler hopes that you can simply refer to the content of this article in future use.
