Problems solved by technology

In the process of assembling the components back to the three-component valve after cleaning or replacing the components, the piston spring will generate a reverse force during the assembly process, often resulting in the need for two people to assemble the three-component valve. The situation where the valve assembly is complete occurs, causing considerable inconvenience
Therefore, the disadvantage of the existing three-component valve is that the sealing ring pad is easy to be worn, and the glue dispensing speed is slow, and the demand for glue with different proportions cannot be realized, resulting in low efficiency during construction.

Abstract

The invention discloses a three-component valve. A valve body comprises an upper valve body and a lower valve body, wherein the upper valve body comprises an upper valve body shell and a drive mechanism arranged in the upper valve body shell; a cavity is reserved in the upper part of the lower valve body; at least three piston channels are arranged in parallel at the bottom in the cavity; a glue outlet hole is reserved on the tail parts of each piston channel; a piston is arranged on the middle parts of each piston; the sealed ends of each piston are at least partially arranged in the corresponding glue outlet holes; at least one sealing device is arranged between each piston and the corresponding piston channels; the top ends of the pistons arranged in parallel are fixed on the same connecting plate which is at least provided with a connector; the connector is connected with the drive mechanism at least by one drive shaft; and the at least one drive shaft is arranged in a drive shaftchannel arranged between the upper and lower valve bodies. The invention provides the dispensing three-component valve, which has the characteristics of quick, convenient and accurate dispensing, clean dispensing stoppage and sealing structure difficult to damage.

Description

technical field [0001] The invention relates to a three-component valve, in particular to a three-component valve provided with pneumatic control, which is used to improve the accuracy of precise glue dispensing. Background technique [0002] Nowadays, the application of three-component valves to glue components in the packaging process is quite common. Traditionally, the structure of three-component valves is mostly composed of four base screws and four cover screws to connect a cover, a piston spring, A device composed of structural components such as a piston, a body, a needle valve, a valve seat body and a tail seat. When the three-component valve is input with a glue, and the needle valve is driven by the piston, the glue can be pushed out by the needle valve to achieve the purpose of dispensing. The porous three-component valve device It is a three-component valve structure formed by bolting many components together with screws. In the dispensing process of the three...
