Problems solved by technology

However, the structure of the existing screw valve is complex, the number of parts is large, and disassembly and assembly are very troublesome.
Such a complex structure will also lead to inaccurate positioning of the screw and stator of the screw valve, and eccentricity is prone to occur during operation, resulting in increased radial runout of the screw rotation and aggravating the rotational wear between the screw and the stator

Abstract

The invention discloses a single-liquid screw valve. The single-liquid screw valve comprises a shell, a valve body upper assembly, a valve body assembly, a glue barrel, a fixing piece and a glue conveying assembly. The shell is arranged on the valve body upper assembly, the bottom of the valve body upper assembly is connected with the valve body assembly, and the glue barrel is fixed to one side of the shell through the fixing piece. By the adoption of the structure, the number of parts is minimized when the screw valve is disassembled, assembled and cleaned, disassembly and assembly are convenient and rapid, and the man-machine efficiency is high.

Description

technical field [0001] The invention relates to the field of screw valve devices, in particular to a single-liquid screw valve. Background technique [0002] In the process of electronic manufacturing and processing, a glue dispenser is needed to drip glue, paint or other liquids in the product process onto the surface or inside of the product. The dispensing process requires the use of a single-liquid screw valve to squeeze the glue into droplets to point onto the device. However, the existing screw valve has a complicated structure and a large number of parts, and disassembly and assembly are very troublesome. Such a complex structure will also lead to inaccurate positioning of the screw and stator of the screw valve, and eccentricity is prone to occur during operation, resulting in increased radial runout of screw rotation and aggravated rotational wear between the screw and stator. Contents of the invention [0003] In order to overcome the defects of the prior art, ...
