The knob is a hand-operated, manual-operated component. According to the functional requirements are divided into continuous rotation, the rotation angle can reach 360 °; also do positioning rotation. Classification of its shape can be divided into circular knob, multi-knob, pointer knob, manual turntable and so on.

Thermocouple is a temperature sensor, is an instrument, it directly measures the temperature, and the temperature signal into a thermoelectric power signal, through the electrical instrument (secondary instrument) into the measured medium temperature.
An adapter is an interface converter that can be a standalone hardware interface that allows hardware or electronic interfaces to be connected to other hardware or electronic interfaces, or to information interfaces. For example: power adapter, tripod base adapter parts, USB and serial port switching equipment.
The basic principle of thermocouple temperature measurement is composed of two different components of the material composition of the closed loop conductor, when there is temperature gradient at both ends, the circuit will have a current through, then between the two ends there Seebeck electromotive force - thermal EMF, This is the so-called Seebeck effect. Two different components of the homogeneous conductor for the hot electrode, the higher the temperature end of the work side, the lower end of the temperature free end, the free end is usually at a constant temperature. According to the thermoelectromotive force and temperature as a function of the thermocouple indexing table; indexing table is the free end temperature at 0 ℃ under the conditions obtained, different thermocouples with different index table.
Gas burner, also known as gas-fired heating boilers and gas bath boilers, gas boiler, as the name suggests refers to the fuel for the gas boiler, gas boiler and oil-fired boiler, gas boiler, gas boiler, gas boiler, Electric boilers are the most economical, so most people have chosen the gas boiler as the steam, heating, bathing with the boiler equipment.
Burner to gas, fuel and other fuel, its thermal efficiency level, the key factor is the gas and air mixture ratio to make full use of the fuel must make it complete combustion. The traditional burner uses diffusion combustion technology, gas and air mixed side of the combustion, the mixing speed is slow, the flame temperature is low, the gas can not be completely burned, prone to carbon monoxide, poisoning.
Gas electromagnetic valve is a gas pipeline safety emergency cut off device. It can be connected with the gas leakage alarm system or with the fire and other intelligent alarm control terminal module connected to achieve on-site or remote automatic / manual emergency cut off the gas source to ensure gas safety. When a strong and harmful vibration occurs, the valve automatically closes. Open the valve to be subject to manual intervention, manually open to meet the safety management practices, in line with the characteristics of accident handling.
When thermocouple heat, it will generate thermoelectri power, which make the magnet/solenoid valve work properly. Specific working principle for gas appliance as follows: When you press the knob, a small fire lit by its flame heating thermocouple, thermoelectric power generation. Thermoelectric power through the wire introducing electromagnetic coil generates a magnetic field pull the magnet/solenoid valve, the gas valve opens, the combustion passage is open, maintain its normal combustion. In the event of high winds or spill soup, etc., putting out the fire, the thermocouple power drops quickly to zero, the coil energized, magnet/solenoid valve failure, rapid reset in spring, the valve closes the gas path, terminate gas supply to ensure safety.
Gas pipe is a special gas pipeline. With metal gas hose hose to replace the traditional way of rubber buckle hose, rubber tube can easily fall off, easy to aging, easy to insect bites, short life defects.
