Do you know what the function of the regulator is?
Author:
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.
Small voltage regulators are contact type, the capacity is generally below 30KVA, single-phase 220V input, 0-250V output; Three-phase 380V input, 0-420 output.
There are many types of large-scale voltage regulators, and the capacity, specifications, and can be designed and produced according to customer requirements. The most common voltage regulator is a kind of voltage regulator, so we also call it automatic voltage regulator.
Voltage regulator function: adjust the output voltage
Working principle:
The pressure regulator is composed of five parts: intake valve body, intake valve body, outlet valve body, and commander. The intake valve body is equipped with a main valve pressure regulating spring, high-pressure gas cylinder sleeve, and sealant film. Wait. The outlet valve body is equipped with a fixed valve seat, which forms a sealing pair with the high-pressure gas cylinder sleeve.
When the conductor is closed, the high-pressure gas cylinder is tightly attached to the fixed valve seat under the action of the main valve spring to close the medium in the pressure regulator; when the conductor is opened, under the action of the pilot gas of the conductor, The sealing film pulls the sealing film pressure plate to press the spring to make the high-pressure gas cylinder sleeve leave the fixed valve seat. The larger the command valve is opened, the larger the gap between the high-pressure cylinder sleeve and the fixed valve seat, so as to realize the function of adjusting the air flow pressure and the flow rate.

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.
