It is higher, generally within 40um, but can all there be a small amount of thicker block in material, especially insoluble fibre content is higher
When, material is very uneven, is easy to cause pressure instability.When superelevation pressure (> 90MPa) works, gasket is easy broken homogenizer
Broken, broken gasket enters in material, is particularly easy to blocking homogenizing valve, the pressure of material in pressure chamber is caused sharply to increase,
Cause danger.Since this pressure stabilizing homogenizer is equipped with filter in pressure chamber, material enters pressure by check valve from plunger cavity
Power chamber, material are filtered in pressure chamber by the filter of reticular structure, since filter is by the thicker block in material
It filtering out, under the action of certain pressure intensity, material can pass through the gap of valve seat and mandril, homogenizing valve will not be blocked,
It will not be stuck in the gap of valve seat and mandril, so the homogeneous micronization processing to material can be smoothly completed, material in pressure chamber
Pressure is not in big fluctuation, to realize the purpose of homogenizer automatic voltage regulation.
Advantages of the present invention and effect are: the present invention solves instead of previous band over-pressure safety device homogenizer
The problem of pressure instability when matter machine super-pressure.The present invention solves pressure instability when homogenizer super-pressure with simple form
