Examples:
as shown in fig. 1-6, the utility model provides a signal valve block for a filling industrial pump, which comprises a signal valve body 1, wherein a first plug-in type logic valve 2 and a second plug-in type logic valve 3 are installed at the top of the signal valve body 1, a first oil port 1.1 is arranged on the right side surface of the signal valve body 1, a second oil port 1.2 and a third oil port 1.3 are arranged at the top of the signal valve body 1, a fourth oil port 1.4 is arranged on the left side surface of the signal valve body 1, a fifth oil port 1.5 and a sixth oil port 1.6 are arranged on the back surface of the signal valve body 1, a first valve oil port 2.1, a second valve oil port 2.2 and a third valve oil port 2.3 are arranged on the first plug-in type logic valve 2, and a fourth valve oil port 3.1, a fifth valve oil port 3.2 and a sixth valve oil port 3.3 are arranged on the second plug-in type logic valve 3.
Further, the second oil port 1.2 is communicated with the first valve oil port 2.1 of the first plug-in logic valve 2.
Further, the fifth oil port 1.5 is communicated with the second valve oil port 2.2 of the first plug-in type logic valve 2.
