## Abstract

The disclosure relates to the technical field of hydraulic pneumatic systems, in particular to an electric control valve detection plug and an electric control valve signal detection method. The disclosure can accurately measure the electric control signal actually obtained by the valve, thus avoiding the risk of misjudgment. The disclosure has simple manufacture and convenient installation and disassembly.

## Claims

### Claim 1

An electric control valve detecting device for detecting whether the transmission of an electric control signal to an electric control valve is normal, the electric control valve has a power plug and a first terminal for receiving the electric control signal from the power plug,
the electric control valve detecting device comprising an armature and an insulating block,
wherein one end of the armature is a socket which is configured to receive and electrically connect with the first terminal of the electric control valve;
the other end of the armature is a terminal, which is configured to be plugged into and electrically connected with the power plug of the electric control valve;
a mounting groove is arranged in the insulating block, and the armature is arranged in the mounting groove;
the side surface of the insulating block has detection holes, which are communicated with the mounting groove.

### Claim 2 (depends on 1)

The electric control valve detecting device according to claim 1, wherein the number of mounting grooves in the insulating block is 3.

### Claim 3 (depends on 1)

The electric control valve detecting device according to claim 1, wherein the number of detection holes arranged in the insulating block is 3.

### Claim 4 (depends on 1)

The electric control valve detecting device according to claim 1, wherein the top of the insulating block mounting groove is provided with a protrusion.

### Claim 5 (depends on 1)

The electric control valve detecting device according to claim 1, wherein a through hole is arranged in the center of the insulating block, the through hole is configured to receive a plug fixing bolt to fix the power plug and the electric control valve detecting device.

### Claim 6

A method of detecting whether the transmission of an electric control signal to an electric control valve is normal by using an electric control valve detecting device, wherein
the electric control valve has a power plug and a first terminal for receiving the electric control signal from the power plug,
the electric control valve detecting device comprising an armature and an insulating block,
one end of the armature is a socket which is configured to receive and electrically connect with the first terminal of the electric control valve;
the other end of the armature is a terminal, which is configured to be plugged into and electrically connected with the power plug of the electric control valve;
a mounting groove is arranged in the insulating block, and the armature is arranged in the mounting groove;
the side surface of the insulating block has detection holes, which are communicated with the mounting groove
wherein the method comprises the following steps:
Unplugging the power plug of the electric control valve to be measured;
Inserting the first terminal of the electric control valve into the socket end of the electric control valve detecting device, and inserting a terminal end of the electric control valve detecting device into the power plug of the electric control valve;
extending a multimeter into the detection hole on the side surface of the electric control valve detecting device to measure the electric control signal actually received by the first terminal of the electric control valve.
