Description

Technical Field

[0001] The utility model belongs to the technical field of glue dispensing equipment, and in particular relates to a switch type inlet and outlet valve body. Background Art

[0002] The glue dispensing process is to attach glue to the product by coating, encapsulating, dripping, etc., so as to achieve the pasting, encapsulation, insulation and fixation of the product. When dispensing glue, the glue dispensing equipment generally uses a metering valve to slightly adjust the glue output.

[0003] Existing metering valves for glue dispensing machines generally use diaphragm piston metering valves, in which the piston rod in the diaphragm piston metering valve pushes the diaphragm to move, so that the moving diaphragm controls the flow of glue fluid, and the shape and position of the diaphragm are changed by the movement of the piston rod, thereby affecting the opening or closing of the fluid channel and adjusting the glue output. However, when the fluid channel is opened or closed by the movement of the diaphragm, the diaphragm is brought into contact with the fluid channel of the valve body due to the back and forth movement of the piston rod, so that the diaphragm is brought into contact with the inner wall of the fluid channel when moving. During the back and forth movement, the diaphragm is easily worn, resulting in the diaphragm not sealing the fluid channel tightly enough, which easily causes glue leakage. Therefore, the diaphragm in the metering valve needs to be replaced regularly, which increases the maintenance time and reduces the work efficiency. Utility Model Content
