Advantages of natural gas break valve

The emergency disconnection system of the natural gas pull-off valve has largely ensured the safety of fluid transportation in marine and land crane pipes. With a simple and unique design, when the crane tube exceeds the rated capacity of the operating system, this system can be automatically and safely disconnected in the crane tube without any leakage. This has the advantage of ensuring triggering in the event of a danger, closing the valve instantaneously, very few drips and relatively small pressure losses. The breaking mechanism must ensure that the equipment can be automatically and quickly disengaged during "emergency disengagement"; also ensure that there is a "buffer period" before disengagement to avoid "disengagement" during normal operation and affect normal loading and unloading operations.

Natural gas is a multi-component mixed gas. The main component is alkanes, of which methane is the majority, and a small amount of ethane, propane, and butane. In addition, it generally contains hydrogen sulfide, carbon dioxide, nitrogen, and water vapor, and Trace amounts of inert gases, such as helium and argon. Under standard conditions, methane to butane exist in a gaseous state, and liquids below pentane are liquid. Natural gas-based paleontological remains have been deposited underground for a long time, and the gaseous hydrocarbons produced by slow transformation and metamorphic cracking are flammable. They are often accompanied by pure oil gas fields when crude oil is extracted from oil fields.

Natural gas is contained in underground porous rock formations. The main component is methane, with a specific gravity of about 0.65. It is lighter than air and is colorless, odorless, and non-toxic. Natural gas companies have added odorants (tetrahydrothiophene) in accordance with government regulations for the benefit of users. Natural gas can suffocate when it reaches a certain level in the air.

If the concentration of natural gas in the air is in the range of 5% to 15%, it can explode when exposed to open flames. This concentration range is the explosion limit of natural gas. The explosion produces high pressure and high temperature in an instant, and its destructive power and danger are very great.

According to the state of natural gas storage, it is divided into three types: structural natural gas, water-soluble natural gas, and coal mine natural gas. Structural natural gas can be divided into wet natural gas accompanied by crude oil and dry natural gas without liquid components.
