Gas Control Valve Troubleshooting

A water heater gas valve controls the pilot light, water temperature and it has a
safety limit to shut everything down.To check the pilot control of gas patio heaters , follow the lighting instruction on the water heater. Do not try to light the pilot if you smell gas.Press the pilot button down and light the pilot.If the pilot lit but will not stay lit when the pilot button of gas safety burner valve is released the water heater thermocouple could be the problem.If the thermocouple has been replaced and it has been properly installed (tip of the probe in pilot flame, thermocouple screwed in tight at the control valve,thermocouple line not kinked) and still the pilot will not stay lit when you release the pilot button then the gas control valve is at fault.If the pilot will not light at all with the pilot button down check the gas supply.You have gas and the pilot still will not light, the pilot line or orifice may be clogged.

The advantages of pressure regulating valve

A pressure regulating valve, also known as self-balancing valve, flow control valves, flow control, dynamic balancing valves, flow balancing Gas Valves, is an intuitive and easy flow regulation control device, the pipe network application gas patio heater valve can be set directly from the design constant flow, the valve can be in the action of water flow automatically eliminate the remaining pipeline pressure head and pressure fluctuations caused by deviation, no matter how the pressure changes in the system are kept constant flow setting, the gas oven safety valve These features enable a complete network flow regulator to tune into a simple flow net work distribution, effective solution pipe network hydraulic imbalance.

Pressure regulating valve without external energy, energy in the absence of electric airless workplace, convenient and saves energy.

The trend of valve in manufacturing technology

with the changing environment of industrial technology, advanced manufacturing technology are eager to enter the Gas Heater Valve manufacturing. Most manufacturers are in the application of advanced manufacturing technology, investment and manufacturing execution systems used to achieve process automation and CNC machine tools, die-casting, the whole mold and other high precision molding technology, high-precision grinding machines, high efficiency and precision processing technology, surface modification and coating of special processing and material modification technology to produce sophisticated, usable, reliable, high-quality products --- gas oven safety from tiny to large diameter valve; from the traditional to the eccentric single seat valve type rotary valve, V-type ball valve, axial flow valve; from the anti-surge, anti-cavitation cavitation, abrasion resistant to high temperature and pressure regulating valve special valve, special valve; from the big thrust of the pneumatic actuator to quickly respond to the electric actuator; from safety assurance process tightly closed to ensure the environment ultralow leakage. Regulating valve and the development of petroleum and petrochemical process control simultaneously, the formation of the whole process, large-scale, high-parameter products, basically meet the control requirements for petroleum and petrochemical production.

How to Installate the part of gas grill valve

1 cut-off valve
According to install shut-off valves premises may be orientation during installation to stem hydraulic ferrule vertical as well. Medium flow direction of medium flow from the bottom of the gas grill valve disc valve
Top of the plate, according to media flow arrow on the valve body marked for installation.
2 Gate
In addition valve installed in the Japanese metric thread pipe condition, stem mounted vertically as possible. However, according to the spatial location of the cabin, hand wheel vertically downwards
Installation is also possible. Flow direction is no requirement, but should be considered after the installation instructions can switch easy to observe.
3 Check Valve
Lift check valves should be installed over gas grill valves plate vertically. Swing check valves installed in horizontal pipe, valve disc is rotated upward when opened. Installed in vertical
Straight pipe, valve disc is located in the upper part of the seat. When installing medium flow direction of media flow valve shall be indicated by the arrow on the sign.
4 non-return valve
Closing check valve body should be medium flow arrow on the sign to be installed when you install to stem vertical as well.

the two main functions of set fire gas valves water heater

The one main functions of set Gas Cooker valve water heater is to use it to ignite the main burner; The second main functions of set fire gas valves water heater is to use its uninterrupted heated thermocouple. Thermocouple is a heat can be converted into electrical energy components, installed next to the fire, the heat generated by its current control solenoid hydraulic cutting machine, open gas cookers in the supply channel, so as to achieve the maintenance supply, continued to ignite the fire purposes. Water heaters used for a period of double hose connector time, prone to fire and flame failure can not be sustained. Its causes and treatment methods are as follows.

QUS cooking valve-20 Series

The small gas cookers freestanding is the best design for the cookers.price also is the competitive.male or female easy to control. and the head to the centre of Gas cooking valve is the most important.the production can be 30000pcs per days.

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
