What is a gas valve?
The gas valve is a device used to control gas flow using the system. Whether it is placed on a pipe or storage tank, the gas valve allows to stop the flow or allow the gas flow around the valve point. The gas valve is usually made of brass material and is designed when it is turned so that it does not create a spark. Usually, there is a gas valve on the gas power line to any appliance on the device carburetor. When trying to work on the device, it is recommended that the valve on the supply line is converted to the "OFF" position.
Most of the gas fittings use the fiber counterclockwise. This is the other way around to any other assembly. The purpose of this fiber design is to ensure that a hazardous gas valve cannot be installed in the gas line. For example, a water shut -off valve or other substance could be made of steel; This type of valve could spark and cause an explosion when installed on a gas line. By using the specifications of the gasOnly for fiber mounting, potential for this type of difficulty can be eliminated.
When installing any new gas valve or assembly, it is wise to use a bubble test to ensure that no leaks are present. The bubble test is performed using a mixture of soap and water and applied to all gas lines. Any gas leak causes a bubble to form in soapy water. If some bubbles are detected, the assembly must be tightened or redesigned. Quality connection will usually include the use of Teflon liquid or tape sealant applied to fibers.
Many gas valves used on the main power lines will include a locking eye. A lock out is a device created in the valve that allows the installation of the padlock. This lock keeps the valve in a closed position until it is removed by the person who installed it. This is a safety classesIt is used to prevent manipulation or random gas flow an open line that could result in an explosion or poisoning of people around.
Many gas valve patterns used on heater and furnaces require the user to push the valve down and hold it to light the unit. This is another security function to make the unintentional ignition of gas more difficult. By creating such safety devices in the gas valve, random fires, explosions and death can be reduced.
