The gas valve is a new safety device for natural gas pipeline engineering; it is used to cut, connect and regulate the gas in the pipeline, with good control characteristics and sealing performance. Applicable to natural gas, liquefied petroleum gas, natural gas, oxygen and other pipelines.

The following points should be noted when using natural gas pipeline valves:

1. The natural gas transported by the pipeline contains a large amount of hydrogen sulfide (this is a toxic and corrosive gas) before desulfurization. Even natural gas treated by a process such as desulfurization still has residual hydrogen sulfide. Therefore, the choice of pipeline valves should be selected from corrosion-resistant sulfur-resistant materials.

2. At present, the valves used in urban natural gas pipelines are more than 100 kilometers long. They can only be patrolled and inspected regularly, and sometimes the pipelines need to pass through areas with complicated conditions. The loss of medium may cause serious fire accidents. Especially for pipelines close to the city, it is particularly important to prevent the leakage of the valve.

3. Once the pipeline is put into operation, it is not allowed to stop running within a few years. It is not allowed to have a momentary interruption, and there is no overhaul period. Once the pipeline valve connected in series on the pipeline fails, the consequences are unimaginable. Therefore, the consumable parts of the pipeline valve require a long service life.

4. The control personnel generally have reliable control performance on the valve in the station or in the control room, and the valve itself is required to have protection and explosion-proof measures. Especially for long-open valves, it is required to make an accurate cut in the sudden change of the situation. Therefore, reliable control performance is the focus.

The above is the use of natural gas pipeline valves summarized by Anhui Pneumatic Ball Valves. For more information on valve information, please pay attention to the official website of Hefei Zibo Luo Industrial Control Equipment.
