Technical Field

[0001] The utility model belongs to the technical field of glue coating, in particular to an on-off valve for discharging two-component glue. Background Art

[0002] The gluing industry primarily involves the research, development, production, and application of gluing materials, which are widely used in various fields to provide products with various functions such as moisture resistance, corrosion resistance, insulation, and decoration. During the gluing process, to facilitate the control of glue flow, on-off valves are installed to control the flow and cutoff of glue.

[0003] However, through research and investigation, combined with actual glue application experience, we found that some existing on-off valves have complex structures, are prone to glue leakage and dripping, and have a single function, directly discharging glue through the on-off valve without the ability to install monitoring devices. With the continuous advancement of glue application technology, existing on-off valves are no longer able to meet actual usage needs. Therefore, there is an urgent need to improve the existing glue dispensing on-off valve and provide an on-off valve for two-component glue dispensing. Utility Model Content
