The main components of the press pump head are:
Piston: The piston performs reciprocating motion inside the pump head, changing the size of the space inside the pump head by moving up and down, thereby affecting the pressure and flow rate of the liquid.
One way valve: composed of glass or steel beads and a funnel, ensuring that liquid can only flow in one direction, from the liquid storage room to the outlet pipe.
Spring: Used to restore the position of the piston. When the pump head is released by hand, the spring pushes the piston upward, reducing the pressure in the liquid storage chamber and allowing the liquid to flow back to the storage chamber.
Conduit and outlet: Connect the liquid storage room and outlet to guide the flow of liquid.
