In the suction seat at the bottom of the single tube sprayer, there is an inlet valve. There is an outlet valve on the outer wall of the tube inside the air chamber. There are copper balls in both valves. During the work, due to the change of pressure, the copper ball is jumped up and down to open and close the valve to control the flow of the liquid.
When the plug rod rises, the space inside the tube is suddenly increased, thus forming a partial vacuum. Under the action of atmospheric pressure, the liquid rushes through the copper ball in the inlet valve and enters the tube. When the plug stem is pressed, the copper ball in the inlet valve closes the inlet hole. The liquid that has entered the tube of the tube can only flow out from the upper part of the tube of the tube through the hole of the outlet valve, push the copper ball in the outlet valve and enter the chamber. The liquid is gradually increased, and the air in the air chamber is compressed to generate pressure. The larger the compression ratio, the greater the pressure generated.
The pressurized chemical liquid passes through the water outlet joint and enters the high-speed swirling flow in the vortex chamber through a conduit (a hose, a spray bar, etc.) to generate a vortex. Due to the centrifugal action of the vortex and the difference between the pressure inside and outside the orifice, the liquid solution forms a mist after passing through the orifice.
