Operations Guide-Gas Cooker valves

The gas fire unreasonable or can not maintain the channel conduction is the root cause of the fault.skiving machine If the thermocouple or the Gas Cooker valves failure, fire or clogged nozzles will result in the supply passage barrier. When the thermocouple poor performance, even though it burned red, still no release after the fire when the ignition hand, can not hear the sound operation of the gas cookers freestanding. In addition to external thermocouple failure, cracks or loose electrode leads are not likely to result in sustained ignition failure. If the hand release missing after the fire, but could hear the sound of the solenoid valve is released, it is clogged nozzle, then fire supply pipe can be removed with fine copper wire poke at the dirt can clog. If you have a fire after the hand release, but soon after automatically extinguished, it is caused by reason of the thermocouple. Can try to re-adjust the position of its best heat generally able to troubleshoot.

the structure of the gas control valves

Department of the gas valve through the gap, resulting in the loss of resistance to pressure to achieve Gas Control Valve the purpose of decompression. By end-use, the valve can be divided according to the different uses: 1 breaking with: to connect or disconnect the gas pipeline, such as the Gas Control Valves, gate valve, ball valve, butterfly valve. 2 ended reuse: to prevent the backflow of gases, such as check valves. 3 adjustment: adjust the gas pressure and flow, such as valves, valve. 4 assignment: to change the flow of the gas, gas distribution, such as the three-way cock, dispensing valve, spool valve. Press the drive mode, depending on the driving mode can be divided into: 1 Manual: With hand wheels, handles, levers or sprockets, etc., there are human-driven, large transmission torque when fitted with reduction gear worm gear. 2 Electric: With motor or other electrical device driver. 3 air; driven by compressed air.

If this is the case, one reason is because the supplement to the cold water pressure inside the water heater pressure is greater than the take-off safety valve caused, so even without heating relief valve in the drip, particularly at night, when low water peak, municipal water net of higher pressure, this phenomenon is more obvious, to solve this problem valves can be installed on the home's water pipes, the water pressure from the high pressure of municipal water network drops a suitable pressure, so you can ensure that the entire house The pressure is not overpressure, and can play a very good water-saving effect; if the cold water pressure is not too high dripping, then there may be a safety valve is broken, the proposed replacement of a quality assurance of the safety valve

Burner valve Symptom Remedy

gas Burner ValvesSymptom Remedy
1, power, press Start, the motor does not turn
(1) The pressure does not satisfy the condition (1) adjusting the air pressure to a predetermined value
(2) solenoid valve lax, joints leak, check the locks (2) clean or repair the solenoid valve pipe fittings
(3) Thermostat Open (3) Check the thermostat is closed
(4) at least one loop condition does not hold (4) check the water level, pressure, temperature gauge whether
2, before the start of the purge normal, but the point does not fire
(1) Burner ungrounded (1) access to the circuit ground
(2) solenoid valve does not work (the main valve, ignition valve) (2) renewal
(3) pressure unstable (3) adjusting the air pressure to a predetermined value
(4) the amount of wind is too large (4) decreases with the wind, reducing the throttle opening
3, the point does not fire, the air pressure is normal, there is no ignition power
(1) The ignition transformer burned out (1) renewal
(2) high-voltage damage or loss, (2) to re-install or renewal
(3) the gap is too large or too small, the relative dimensions of the ignition rod position (3) readjust
(4) electrode breakage or reinstall or replace shorting (4)
(5) inappropriate pitch (5) readjust

Safety valve heating and electric water heater with hot water leakage when no one

If this situation is normal, as mentioned above, when no hot water, electric water heater there is equivalent to a closed system, this time inside the water is heated, temperature, volume expansion, but because electric water heater tank volume is constant, there is no place to absorb the expansion water, so the water pressure inside the water heater will be increased when the pressure is greater than the take-off when the pressure relief valve, pressure relief valve will take off within the protection of the water heater bile, is what we see in the drip valve. If you want to in this case the safety valve is not dripping, you can install an expansion tank in the Italian Akusitan pipeline between the safety valve and the water heater to absorb the amount of expansion produced after water is heated, the heating time electric heater, water pressure will not rise much;

The difference between safety valve and pressure relief valve

[1] Simply put, the pressure relief valve to prevent the system exceeds a certain value, is mainly used to protect the system, the valve is to reduce the system pressure from a high pressure to the appropriate value required for its export pressure a range, as long as this range can be.
[2] Safety valve: valve is opening and closing pieces by the external force is normally closed state, when the device or media pressure inside the pipe rises above a predetermined value, by medium pressure pipeline or equipment to the outside of the system to prevent the emission medium special valve exceeds a predetermined value. Safety valves are automatic valves, mainly used in boilers, pressure vessels and piping, control pressure does not exceed a predetermined value, for personal safety and equipment operation plays an important protective role. Note the safety valve must be pressure tested before use.
[3] valve: valve by regulating the inlet pressure is reduced to the outlet pressure of a need, and rely on the energy of the medium itself, so that automatically maintain a stable outlet pressure valve. From the point of view of fluid mechanics, pressure reducing valve is a local resistance to change spending components, that is, by changing the throttle area, so that the kinetic energy of change velocity and the fluid, resulting in different pressure loss, so as to achieve the purpose of decompression. And then rely on regulation and control and regulation systems, so that the valve pressure fluctuations and the spring force balanced, so that the pressure after the valve
