Gas self-closing valve, can you use it?
The gas self-closing valve is installed on the indoor gas pipeline of residents. It is generally installed behind the gas meter and in front of the gas appliance. When the gas supply pressure of the gas pipeline is under-pressure or over-pressure, it will automatically close without electricity or other external power. Cut off the gas source, which can effectively prevent gas leakage and issuance accidents.

Do you know what the function of the regulator is?
As the name implies, the voltage regulator is used to regulate the voltage, also known as the voltage regulator. It is generally used in scientific research, experiments, testing, heating and heat preservation, soft start and other occasions to provide different voltages to the load, and the voltage can be linearly adjusted when the power is on.

The working principle and application field of voltage regulator
The voltage at the input terminal remains unchanged, and then a part of the voltage is taken out from the input coil as the output. When the number of turns of the coil changes due to the movement of the slider on the input coil, the output voltage also changes, so as to achieve the purpose of adjusting the output.

The working principle of the voltage regulator
The voltage regulator is an adjustable auto-transformer structure, and the carbon brush of the voltage regulator is assisted by the handwheel spindle and the brush holder. The coil is evenly wound on the annular iron core, the carbon brush is closely matched with the polished surface of the coil under the action of the spring pressure, and the rotating shaft drives the brush holder to make the carbon brush slide along the surface of the coil and change the contact position of the carbon brush, that is, change The turns ratio of the primary and secondary coils enables the output voltage to obtain smooth and infinity adjustment within the adjustment range, so as to achieve the purpose of voltage regulation.
