Dongguan Songjing Ultra-Precision Machinery Co., Ltd. is a manufacturer that integrates the research, development, and production of coating nozzles, as well as provides services. It undertakes various components (control valves, differential heads, T-shaped blocks, injection rods, differential screws, push-pull rods, etc.)

It can be selected based on the diameter of the pipeline. It can also be chosen according to the maximum flow rate and the flow range of the valve.

The differential head is made based on the principle of helical enlargement. That is, when the screw rotates one full circle in the nut, the screw moves forward or backward by one pitch along the axis direction. Therefore, a very small distance moved along the axis direction can be represented by the reading on the circumference.

Diversion function:

The flow rate should be stable. Firstly, ensure that the pressure of each layer of glue is equal during the gluing process. For each glue channel, there is a micrometer. The differential head is connected to the valve core through a coupling. By adjusting the micrometer, the cross-sectional area of the foil adhesive flow channel can be changed, thereby altering the flow rate of each layer of glue.
