The dispensing valve is one of the most widely used glue control accessories in automation equipment. The compound dispensing valve has many characteristics and functions. This single-liquid dispensing valve has become the standard dispensing control accessories for automatic gluer. This paper will briefly introduce the principle and practical application of the single-liquid dispensing valve, including its application in electronic products or shell packaging. Application effect of dustproof and waterproof adhesive.

Application in Surface Coating and Sealing
Like most single-liquid dispensing valves, compound ejector dispensing valves extrude glue by pressure-driven ejector. They have the advantages of simple operation, less preparation and so on. They are mounted on automatic glue dispensing machine to complete dispensing with a wide range of applications. The glue drive is powerful and efficient and stable. When they are used in metal shell dispensing seals of small equipment, the dispensing surface is even and flat. The appearance of bubbles makes it have a certain degree of dust-proof and waterproof ability, and the impact resistance effect is also strengthened. According to this characteristic, it can also be used in small parts to complete waterproof and viscose links.
Among the assembled single-liquid dispensing valves of automatic glue machine, the compound ejector dispensing valve is the main one. The practical application effect is stable and wide. The dispensing effect on the metal shell of electronic parts or small products can be seen.
