First off switch or to close the valve

Gas stove: First off switch or to close the stove valve?
Gas stove switch that switches on the gas stove safety, and now the general and ignition function together. Gas stove valve refers to a valve on the pipe connecting the stove, ventilation rotated 90 degrees, 90 degrees reverse turn off the gas.
So, turn off the heat when it should turn off the valve on a gas stove, because, if the first switch off the stove, may be mixed with air in the pipe connecting the stove again when the ignition could cause an explosion.

The basic operating principle is the stove

The basic operating principle is the stove?
It can be divided into the ignition phase, a mixed fuel, ignition phase, the combustion stage. Ignition phase: ignition pressure to open the gas stove valves, the gas freestanding stoves through the pipeline with some pressure coming from the nozzle; a co-firing: Since the kinetic energy of the gas ejector effect, the nozzle of the gas sucked from the primary air damper, in the ejector completed within a mixed gas ignited stages: the mixture flowing through the fire hole stove, hit the fire source ignition occurs, start ignition; combustion process: after ignition of gas obtained from the secondary air supply around the stove, complete complete combustion.

Turn off the main gas stove valves or not

After the close stove knob, you can not turn off the main gas stove valves?
You can not turn off the stove valves, the stove will not leak, which is built in to confirm the connection is no problem from the gas main valve to the hose connector between the stove (100% airtight, airtight), based on a It can do so. But taking into account the possible hose aging, loose connections and other security risks in use for many years, it is recommended to turn off the main gas valve safer. At the same time, we recommend that users do not have long to turn off the main valve or when taking a trip to prevent leakage.

The entire combustion process of gas burner

Gas burner ignition and stable combustion normal after a few seconds, servo motor drives the throttle opening of the state to the fire, while the proportional control gas burner valves motor cut, and in accordance with the air pressure and the back pressure chamber to control the gas after the gas valve Pressure to adjust the gas volume, stable, efficient combustion purposes. Thereafter, the gas safety burner valve automatically converted size of the fire and stop limit switches according to various demands. Furthermore, the entire combustion process, ionization electrode and the air pressure switch are monitoring the burner.

Home gas valve bad how to do

Home gas valve bad how to do?
If the former is not the case of the Gas cooking valve failure under, you can choose a better quality of the same type of valve, in the case of the gas meter valve before closing their own replacement. After replacing the valve before turning on the gas meter with soap or detergent behind the water evenly in the replacement gas burner safety valve on both sides of the interface, there is no leak bubbles, if bubbles must be turned off before the gas meter valve again, re-the need to replace the valve twice threaded fastening.
Gas valves are widely used for a variety of city gas pipeline network system media pipeline gas, liquefied petroleum gas, natural gas and oxygen; drive in the form of a manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic actuator linkage, can realize remote control and automation.
