Use of gas stoves

1. When using a gas stove valves, to observe the combustion conditions, should not appear yellow flame, black smoke from the flame and phenomena, such as the above phenomenon, please adjust the damper plate inside the stove until a clear blue flame up.
2. When the ignition, you should press the ignition knob, a little pause and then rotate the spark ignition to ensure reliability.
3. Check valve on the pressure gauge on the air supply pressure is consistent with the rated pressure chassis parameters on the nameplate during use.
4. Open the gas supply, check the hose with soap and valves, gas appliance intake port direction, or whether tee interface a gas leak. (The body's internal air tightness has been strictly checked at the factory, if not the body disassembly maintenance, do not detect the air tightness) is strictly prohibited open flame leak! 5. After the leak qualified boot, visual combustion conditions, the air intake throttle adjustment For optimal position (flame clear, light blue color, powerful combustion); ignition ten times, check their firing rate; ignite each burner, put a The outer ring of the burner tune small fire, which blew out after Firelight, check that the knob gas passage is closed, and the other within the burner flame is at a set time (inductive plasma flame protection 8 seconds, thermoelectric flame protection 45 sec) Off.
6. After use, turn off the safety gas valve on the pipe or gas cylinders in order to ensure safety.

Safety valve working principle and structure

gas valve play a security role in the system. When the system pressure exceeds a predetermined value, the valve is opened, the system part of the gas into the atmosphere, so that the system pressure does not exceed the allowable value, in order to ensure the system is not due to excessive pressure and accidents. Also known as relief safety gas valve.
structure type

1, piston valve
Spool is a tablet. Air pressure acting on the piston A, when the pressure exceeds the safety value determined by the spring force, the piston A is the top open portion of the compressed air that is discharged into the atmosphere from the valve port; when the air pressure is lower than the safety value, the spring drive piston down, closes the valve port.
2, valve and diaphragm valve
It works with piston identical. These three are the safety valve spring provides control, adjustable spring preload, you can change the size of the security value, so called direct-acting valve.
3, pilot valve
In a small direct-acting valve to provide control pressure acting on the diaphragm, the diaphragm is the hard core spool, the pressure on the valve seat. When the air pressure is greater than A safe pressure, open the valve, the compressed air is discharged into the atmosphere from the left side of the outlet opening. Diaphragm safety valve and pilot safety valve pressure characteristics of a good, quick action; however, the maximum opening force is relatively small, that is, poor flow characteristics. Practical application, should be based on actual need to select the type of safety valve, and to choose their path according to the maximum displacement.

Features gas valve

1) at the bottom of the Bbq Gas Valves body with a slag hole, easy to exclude dirt. Body interior media path is straight through, without changing its flow direction when the medium flows through the valve, thus a smaller flow resistance. Medium can flow through the valve on both sides from any direction, can achieve the purpose of turning on or truncated.
2) Bbq Gas Valves are clear shot valve stem lift gate drive together, drive screw on the stem in the valve body outside, therefore, can visually determine the shutter opening and closing and the position according to the direction of movement and position of the valve stem, and transmission thread to facilitate lubrication and corrosion from the fluid, but it requires a large installation space.

Gas cooker valve applications

Gas Cooker valves applications
Stove after use should be shut off valve pipe line, because only then will fully burn gas, not only will bring a sense of security, but also save gas and reduce environmental pollution.
If the stove is to shut the door, go off the main valve, you will have that in the rest of the gas flow pipe left in the tube inside, so is unsafe, first turn off the main gas valve the fire will slowly become smaller until extinguished , then turn off the kitchen door, so there would be no circulation tube gas remaining inside.
In addition, you should always check the connecting hoses to whether there is an air leak between the stove. Identify problems in time:
1, regular checks of gas appliances connected to gas pipeline and hose whether compressed, aging, the interface is loose, whether or rat chewed a sharp object, such as the occurrence of the above phenomenon should immediately contact the gas company.
2, regular replacement hose. According to the gas safety regulations and technical specifications, the hose should be replaced once every two years. Due to the quality of various different hose brand, for the user's own safety, it is recommended to replace the hose once a year, you should consciously do this.

Introduce gas safety valve

Bbq Gas Valve spring and the rod two categories. Another impulse safety valve, Pilot Safety Valves, safety valve switch, safety release valve, safety valve and other static weight. Spring-loaded safety valve spring force and rely mainly on the work of the spring-loaded safety valve in closed and not closed, generally flammable, explosive or toxic media should use closed, steam or inert gas can be selected is not closed type, spring-loaded safety valve in there with a wrench and without wrenches. The main role is to examine the extent wrench flexible valve flap, and sometimes can also be used manually with emergency relief. Lever-type safety valve lever hammer mainly rely on force and work, but because of the huge volume of leveraged safety valve is often limited range of choice. Selection radiator valve with higher temperatures.
The main parameters of the gas safety valve displacement, this displacement depends on the caliber of the valve seat and valve opening height, by the opening of different height, it is divided into Weiqi the entire Kai two. Weiqi is the valve opening height for the seat throat diameter of 1/40 ~ l / 20. Entire Kai is the valve opening height for the seat throat diameter of 1/4.

valve

Pilot valve is to rely on the media discharged from the pilot valve to drive or control. The pilot valve itself is a direct-acting valve, sometimes with other types of gas valve Pilot safety valve for high pressure, large diameter occasions. The main valve pilot valve can also be designed to rely on the working medium to seal the form, or may be applied to much larger than the direct-acting valve mechanical load on the valve, which has a good sealing performance. At the same time, it moves less affected by back pressure. The disadvantage is that it is reliable Aluminum safety gas valve with a main valve and pilot valve related action as a direct-acting valve as quickly, reliably, and more complex structure.
