Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 8 The utility model provides a two-component glue potting valve, which is characterized by comprising:

[0031] The valve body 1 is provided with a glue injection cavity 101 inside, wherein the glue injection cavity 101 is provided with a piston cavity 102 and a glue injection channel 103 which are connected to each other, and a glue inlet 104 is also provided inside the glue injection cavity 101, wherein the glue inlet 104 is connected to the glue injection channel 103, and the number of the glue injection cavities 101 is two;

[0035] The utility model embodiment provides a two-component glue potting valve, including: a valve body 1, a driving mechanism 2, a piston valve 3 and a mixing tube 4, wherein two injection cavities 101 are arranged in the valve body 1, and the number of the driving mechanisms 2 is two. When in use, the driving motor 201 first drives the piston 202 to move to the first position, so that the piston 202 is located at the lower part of the piston cavity 102, and the gas in the piston cavity 102 and the injection channel 103 is discharged, and the injection channel 103 is closed by the piston valve 3, and the colloids of the two components A and B enter the injection cavity 103 from the two injection ports 104 respectively. The glue channel 103 and the piston cavity 102 are pressed, and the piston 202 is made to rise. After the glue is injected, the glue injection channel 103 is opened, and the piston 202 is driven by the two driving motors 201 to squeeze out the two components A and B from the two injection channels 103 respectively. The driving motor 201 is a stepping motor, which can adjust the operating parameters according to the different ratios of the two glues, so as to control the stroke of the piston 202, thereby controlling the glue output of the two glues.

[0037] In this embodiment, the piston valve 3 includes a glue discharge valve core 301. When the glue injection channel 103 needs to be opened, the glue discharge valve core 301 is separated from the glue discharge valve cavity 105 to connect the glue injection channel 103. When the glue injection channel 103 needs to be closed, the glue discharge valve core 301 blocks the glue discharge valve cavity 105 to close the glue injection channel 103. The glue discharge valve core 301 is used to close or open the glue injection channel 103. When injecting colloids of components A and B, the colloids are prevented from leaking into the mixing tube 4, which affects the proportion of the mixed colloids and improves the accuracy.

The glue inlet valve core 302 and the glue outlet valve core 301 can be slidably inserted on the piston valve body 304. When it is necessary to pass through the glue injection channel 103, the glue outlet valve core 301 drives the sealing diaphragm 303 to block the glue outlet valve cavity 105 together, so that the glue injection channel 103 is closed; when it is necessary to close the glue inlet port 104, the glue inlet valve core 302 drives the sealing diaphragm 303 to block the glue inlet valve cavity 106 together, so that the glue inlet port 104 is closed.

It slides on the piston valve body 304 and blocks the glue inlet valve cavity 106. When the glue injection channel 103 needs to be closed, the air inlet channel 307 corresponding to the glue outlet valve core 301 is ventilated, and the gas from the external air source squeezes the pressure diaphragm 306 to drive the glue outlet valve core 301 to slide on the piston valve body 304 and block the glue outlet valve cavity 105. The glue inlet valve core 302 and the glue outlet valve core 301 are driven to operate by the external air source, and the structure is simple and reliable, and the operation is easy.

When the piston 202 rises to the position of the full glue sensor 205, the glue injection is stopped. By setting the full glue sensor 205, it is possible to avoid injecting excessive glue, which may cause the glue to overflow from the piston chamber 102 and cause a safety hazard.
