Gas ball valves are a common type of valve that is widely used in gas piping systems to cut off or regulate the flow of fluids. The core component of a gas ball valve is a spherical spool whose surface is usually hardened to resist wear. There is a through hole in the center of the spool, that is, the fluid channel, through which the gas can flow when the stem rotates so that the ball rotates to align with the through hole and the pipe axis; Conversely, when rotated perpendicular to the axis of the pipe, the gas flow is cut off.
The gas ball valve works on a simple and efficient principle, and it relies on a 90-degree rotation to open or close. When the handle or actuator rotates the stem, the stem drives the ball in the spool to rotate. Due to this rotating action of the ball, the gas ball valve can quickly switch states to achieve the purpose of controlling the gas flow.
The gas ball valve is designed so that it has good sealing performance when closed. The seat material is usually PTFE or other engineering plastics with some elasticity, which can fit snugly to the surface of the ball and prevent gas leakage. In addition, the tightness and quick shut-off capability of the gas ball valve make it very useful in emergency situations, such as the ability to quickly cut off the gas supply in the event of a gas leak, to ensure the safety of the user.
In daily use and maintenance, gas ball valves also show their superiority. Due to the simple structure, the gas ball valve is not easy to clog and is relatively easy to maintain. It has a long life and durability, making it ideal for long-term operating systems such as gas pipelines.
In short, gas ball valves have become an indispensable part of gas transmission systems due to their reliable performance and efficient control capabilities. When selecting and using gas ball valves, users should take into account their working principles and characteristics to ensure the stable operation and safety of the gas system.
