Description

Technical Field

[0001] The utility model relates to the field of screw valves, in particular to a high-precision double-liquid screw valve. Background Art

[0002] The main components of the screw valve are the screw and the stator. The stator and the screw can form a sealed cavity. The glue liquid is pushed forward by the screw in the sealed cavity. The greater the rotation angle, the more glue will be discharged. Since its feed port is on the rear side and rotates eccentrically, its structure is relatively large. If the screw does not rotate, no glue will be discharged even if the feed port is pressurized.

[0003] When ordinary screw valves are working, they cannot regulate the flow of the fluid well, resulting in that the discharge volume cannot be well controlled. When processing high-viscosity and easy-to-agglomerate substances, they cannot move well in the inner cavity of the screw valve, resulting in a certain impact on the discharge.

[0004] Therefore, it is necessary to propose a high-precision dual-liquid screw valve to solve the above problems. Utility Model Content
