Classification of gas water heater micro switches
The micro switch is based on the push pin type, and can be derived from the button short stroke type, the button long stroke type, the button extra large stroke type, the roller button type, the reed roller type, the roller type, the short boom type, the long boom type, etc. Wait.
The principle of gas water heater micro switch
The gas water heater micro switch is an external mechanical force that acts on the action reed through transmission elements (pins, buttons, rollers, etc.) The contact and the fixed contact are quickly connected or disconnected. When the acting force on the transmission element is removed, the action reed generates a reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is terminated instantaneously. The contact interval between the micro switches is small, the action stroke is short, the pressing power is small, and the on-off is active. Micro switches are used in electronic equipment and other equipment in automatic control and safety protection devices that require frequent switching of circuits.
The function of the micro switch of the gas water heater is to control the ignition. When the water pressure reaches a certain level, the diaphragm inside will open the micro switch through the transmission shaft. When the valve receives a signal, the valve is energized to open the valve to supply gas and start burning.
Daily maintenance method of gas water heater micro switch
1. It is necessary to read the product instruction manual for the cleaning and protection of the gas water heater, and use the water heater according to the operation method indicated by the instruction manual and the nameplate, and carry out preliminary and simple repair, cleaning and maintenance of the water heater;
2. When the gas water heater shows signs of air leakage, water leakage, the flame does not go out after the water is stopped, and the incineration conditions are not good, it should be used in succession, and the gas treatment company or the manufacturer should be notified in time to repair it to prevent unauthorized disassembly and repair;
3. Do not use expired water heater cleaning and protective agents. According to the national standard GB17905-1999 "Safety Disposal Regulations for Household Gas Incineration Appliances", from the date of sale of gas water heaters, the cleaning and protection effectiveness of liquefied petroleum gas and water heaters will be obsolete. 15 years, the cleaning and protection effectiveness of artificial gas water heaters is 10 years old.
4. It is necessary to ensure that the room is well ventilated;
5. On time, please ask some designated professionals or manufacturers to clean and protect the gas water heater, and repair it in time, and insist that the cleaning and protection of the gas water heater can work well.
