The gas solenoid valve is an important device used to control the flow of gas. It is widely used in household gas stoves, gas water heaters, wall mounted boilers and other equipment. However, after long-term use, some common failures may happen to gas solenoid valves, such as air leakage, blockage, solenoid failure, etc.
This article will analyze common faults of gas solenoid valves and provide corresponding solutions to help users better maintain gas solenoid valves.
1. 7 Common Faults and Troubleshooting of Gas Solenoid Valves
1.1 Gas Solenoid Valve Not working: Not Opening or Closing
Possible causes and solutions:
(1) Power supply failure: Check whether the power line is in good contact and whether the power supply output voltage is normal.
(2) Coil damage: Use a multimeter to check whether the coil is normal. If it is damaged, replace it with a new one.
(3) Valve stuck: Check whether the valve is blocked or stuck, and clean or replace it if it is.
(4) Electronic control board failure: The gas electric control board is responsible for controlling the solenoid valve. If it fails, the solenoid valve will not work properly. At this time, you need to contact professionals to repair or replace it.
(5) In addition to the above reasons, there may be other reasons why the gas solenoid valve cannot be opened, such as pipeline leaks, insufficient natural gas pressure, etc. If you have eliminated the above causes and still cannot solve the problem, it is recommended that you contact a professional maintenance personnel for inspection.
1.2 Gas Solenoid Valve Unable to Continue to Work after Being Started
If the gas solenoid valve cannot continue to work after it is started, its internal components may be faulty or clogged and it needs to be cleaned or replaced. In addition, it may be that the circuit of the gas solenoid valve is in poor contact or damaged and needs to be repaired or replaced.
1.3 Gas Solenoid Valve Leaking
Symptoms of failure: There is still gas leakage when the gas solenoid valve is closed, causing the gas equipment to be unable to be used normally.
Possible causes and solutions:
(1) Check whether the solenoid valve is damaged or whether there is looseness at the connection between the valve and the pipeline, and repair or tighten it in time;
(2) Secondly, check whether the gas solenoid valve seal is aging. If it is, you need to replace it with a new seal or replace the whole solenoid valve.
1.4 Gas Valve Solenoid Coil Failure
Symptoms of failure: The coil fails or is damaged, and the opening/closing of the solenoid valve cannot be controlled normally.
Solution:
(1) Check whether the solenoid coil is normal. If there is an open circuit or short circuit, replace it in time;
(2) Check whether the attraction force of the solenoid is normal. If there is any abnormality, clean or replace it.
1.5 Gas Solenoid Valve Making Noise
1. Too fast gas flow velocity: When the gas flow rate is too high, the gas in the valve will pass through at high speed, causing a hissing sound.
2. Valve damage: The gas valve may be loose or damaged, and friction occurs between the gas and the valve when gas flowing, causing a hissing sound.
3. Pipeline problems: There may be some air or impurities in the pipeline. When the gas passes through, it will collide with these objects and produce a hissing sound.
4. Temperature influence: When gas passes through the valve, due to factors such as temperature changes, unstable flow may occur, causing a hissing sound.
If the gas valve makes a hissing sound, ask the natural gas company personnel for timely inspection and repair to ensure the normal flow and safe use of gas. It is recommended to ask professionals for inspection and processing.
1.6 Gas Solenoid Valve Clogged
Symptoms of failure: The inside of the gas solenoid valve is blocked by impurities, causing the gas to not flow normally and smoothly.
Solution:
(1) Regularly clean the inside of the gas pipeline and solenoid valve to ensure smooth flowing;
(2) If serious blockage occurs, the solenoid valve can be disassembled for cleaning and maintenance. Be careful not to damage the seals and springs during cleaning.
1.7 Gas Solenoid Valve Wear
Over time, parts of the gas solenoid valve may wear out, causing it to fail to open and close properly. Solutions include replacing worn parts or the entire solenoid valve.
2. Gas Solenoid Valve Maintenance skills and Maintenance Cycle
2.1 Gas Solenoid Valve Maintenance and Repair
1. Maintenance
It is very important to perform regular maintenance on the gas solenoid valve. Clean and inspect the gas solenoid valve at regular intervals to ensure that its internal structure is not blocked or damaged. Additionally, inspect electric wires and ensure they are in good contact.
2. Test Skills
During maintenance, the gas solenoid valve needs to be tested. You can use tools such as a multimeter to test the circuit to determine if it is normal. In addition, you need to pay attention to safety during testing to avoid dangerous situations such as electric shock.
3. Replace Parts
If the gas solenoid valve malfunctions or is damaged, parts will need to be replaced. When replacing parts, you need to select suitable parts and operate according to the instructions. In addition, you need to pay attention to safety when replacing parts to avoid accidents caused by improper operation.
It is very important to master gas solenoid valve troubleshooting and repair skills. Only after mastering relevant knowledge and skills can we better ensure the normal operation of gas equipment and avoid safety accidents caused by malfunctions.
2.2 Gas Solenoid Valve Maintenance Cycle
The maintenance cycle of a gas solenoid valve is usually related to its use frequency and usage environment. Generally speaking, regular maintenance and inspections are recommended to ensure the normal operation of the solenoid valve.
1. Regular Maintenance
For gas stoves used at home, it is recommended to perform routine maintenance every three months. Maintenance includes cleaning the surface and interior of the solenoid valve, and checking whether the valve is loose or worn.
In addition to routine maintenance, comprehensive maintenance is recommended every other year. This includes disassembling the solenoid valve, cleaning internal components, replacing worn parts, and performing a comprehensive inspection.
3. Pay Attention to Safety
Before performing gas solenoid valve repairs, be sure to close the gas valve and disconnect the power supply. During the maintenance process, wear appropriate protective equipment to avoid accidental injuries.
The above is a brief introduction to common faults and solutions of gas solenoid valves. We hope it can help users better understand and maintain gas solenoid valves. If you cannot solve the problem you meet, it is recommended to contact a professional repairman for inspection and repair. In daily use, it is necessary to regularly inspect and maintain the gas solenoid valve to ensure its normal operation and avoid safety accidents.
