[0002] Glue valves are a type of valve device used in special scenarios of glue coating. They are widely used in manufacturing industries where glue coating processes are used to connect parts. Due to the high viscosity of glue, in addition to the basic structure of an ordinary valve device, in order to reduce the blockage of the valve channel by glue, some complex structures are often needed to increase the suction force or extrusion force, resulting in a complex structure of existing glue valves. In addition, in order to match the complex structure of existing glue valves, there are often many non-standard parts in the components, which leads to an increase in the manufacturing cost of existing glue valves. Therefore, the structure of existing glue valves needs to be further improved. Utility Model Content

[0042] The first air port 1a at the rear end is inletted with air to push the piston shaft 4 forward. When resetting, the first air port 1a and the second air port 3a at the front end are inletted with air at the same time to realize the resetting of the piston shaft 4. At the same time, the resetting member 5 can also provide the restoring force of the piston shaft 4. The glue coating valve of the utility model is provided with the first air port 1a on the driving housing 1 and the second air port 3a on the front housing 3. The double-acting air source structure when resetting the piston shaft 4 in this way overcomes the phenomenon that the resetting member 5 cannot be reset due to the high glue discharge pressure and the insufficient elastic force of the resetting member 5; and the resetting member 5 is retained to ensure that the resetting force can still be provided when there is no air source access.

[0043] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
