A high-pressure gas cylinder pressure relief electrical device with solenoid valve

Abstract

A disclosed high-pressure gas cylinder pressure-relief electric device with a solenoid valve comprises a shell, a control circuit module arranged in the shell, and a plug communicated with the control circuit module and used for matched usage with a high-pressure gas cylinder solenoid valve coil; and the control circuit module comprises a power switch (SA), a switch transformer (Tr1), a rectification filter circuit, an RC absorption circuit, a sampling circuit, a detection circuit, a voltage stabilizing circuit, an automatic overload protection circuit, a regenerative feedback circuit and a workpiece indication circuit. The device is convenient to use, a medium is circulated and pressure is relieved after the high-pressure gas cylinder solenoid valve coil is powered on only by directly inserting the plug into a socket at the high-pressure gas cylinder solenoid valve coil for switching on the power switch of the electric device. After pressure relief is finished, the plug is withdrawn for switching off the power switch of the electric device, and the operation is safe and efficient. In the pressure relief process, the voltage is stable, and the circuit is capable of rapidly automatically cutting off the circuit once the equipment has short circuit, overload and other abnormal cases.

Description

technical field [0001] The invention relates to a gas cylinder pressure relief electrical equipment device, in particular to a high pressure gas cylinder pressure relief electrical device with a solenoid valve. Background technique [0002] In the production process of gas cylinders, after the airtightness test of gas cylinders with solenoid valves, it is necessary to discharge the internal nitrogen gas of about 20MP to normal pressure. Generally, the production process is as follows: 1. Close the manual valve; 2. Use Remove and tighten the nut with a wrench; 3. Rotate the coil counterclockwise with your hand to remove the coil, and pay attention not to lose its accessories after removing the coil parts, so that it can be used for reinstallation; 4. Remove the steel sleeve with a wrench; 5. Remove Lower the steel sleeve and valve core, and be careful not to lose the spring and pin on the valve core; 6. Open half of the manual valve to deflate, because the over-current valve ...
