Detailed Description
The present utility model will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the present utility model, but are not intended to limit the utility model in any way. It should be noted that variations and modifications could be made by those skilled in the art without departing from the inventive concept. These are all within the scope of the present utility model.
Example 1
As shown in fig. 1-2, the non-differential pressure plunger pump of the present utility model comprises a piston 2 and a plunger cylinder 8, the piston 2 being disposed within the plunger cylinder 8. One end of the piston 2 is connected with the upper piston rod 1, the other end of the piston 2 is connected with the lower piston rod 3, and the upper piston rod 1 and the lower piston rod 3 are arranged to be the same in size. One end inside the pressure difference plunger pump is further provided with a first cavity 9 and a second cavity 11, and the pressure difference plunger pump is further provided with a glue outlet.
The first cavity 9 is axially arranged in the differential pressure plunger pump, and the second cavity 11 is radially arranged in the differential pressure plunger pump. The outer one end of pressure differential plunger pump still sets up fixed preforming 4 down and moves down preforming 5, and the interval sets up between fixed preforming 4 down and the movable preforming 5 down. An upper movable pressing sheet 6 is arranged at one end inside the pressure difference plunger pump, and the upper movable pressing sheet 6 is oppositely arranged at the other sides of the lower fixed pressing sheet 4 and the lower movable pressing sheet 5. The non-pressure difference plunger pump is internally provided with a check ball 7, and the check ball 7 is connected to the piston 2.

Example 2
A dispenser comprises the non-differential pressure plunger pump of the embodiment 1.
Principle of operation
According to the utility model, the upper piston rod 1, the piston 2 and the lower piston rod 3 do up-and-down motion in a common circulation way, so that the glue in the plunger pump without pressure difference is continuously output from the first glue outlet 10 and the second glue outlet 12.
When the upper piston rod 1, the piston 2 and the lower piston rod 3 jointly move downwards, the upper movable pressing sheet 6 is pressed and arranged by the pressure generated by the glue, and the glue in the lower cavity 14 is output from the second glue outlet 12; simultaneously, the lower fixed pressing piece 4 and the lower movable pressing piece 5 are arranged separately, the check ball 7 is opened, glue in the first cavity 9 flows into the upper cavity 13 through the channel 15, and the second cavity 11 is filled when the glue in the first cavity 9 flows.
When the upper piston rod 1, the piston 2 and the lower piston rod 3 jointly move upwards, the pressure generated by the glue enables the lower fixed pressing sheet 4 and the lower movable pressing sheet 5 to be mutually pressed; meanwhile, the check ball 7 is closed, the upper movable pressing sheet 6 is opened, glue in the cavity II 11 flows into the lower cavity 14, and glue in the upper cavity 13 is output from the first glue outlet 10.
