Supply of gas source ball valve

Supply of gas source ball valvePneumatic ball valves can be tightly closed with only a 90 degree rotation of the pneumatic actuator and a small rotational torque from the air source. *The equal inner cavity of the valve body provides a low resistance and straight passage for the medium. It is generally believed that ball valves are suitable for direct opening and closing, but recent developments have designed ball valves to have throttling and flow control functions. The main characteristics of ball valves are their compact structure, easy operation and maintenance, suitable for general working media such as water, solvents, acids, and natural gas, as well as for media with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. The valve body of a ball valve can be integral or modular.

Pneumatic ball valves evolved from plug valves. It has the same 90 degree rotation action, but the difference is that the plug body is a sphere with a circular through-hole or channel passing through its axis. The ratio of the sphere to the channel opening should be such that when the sphere rotates 90 degrees, it should all appear spherical at the inlet and outlet, thereby intercepting the flow. This type of valve can be installed at any position in the pipeline.

A gas source ball valve is a type of valve that can be adjusted correctly and has a wide range of applications, such as the cutting distance used for flame cutting, and the knob for adjusting flame temperature is equivalent to a gas source ball valve. The gas source ball valve is an important component of the external measurement pipeline system, primarily consisting of globe valves and ball valves. Its function is to open or cut off pipeline pathways. The valve core of a needle valve is like a pointed cone, piercing into the valve seat like a needle, hence the name.
Exterior valve is a type of pipeline accessory. It is a device used to modify the cross-section of the pathway and the direction of medium flow, and control the flow of the conveying medium. The sealing function of the external valve refers to the ability of each sealing part of the external valve to prevent the leakage of the medium, and it is an important technical performance indicator of the external valve. There are three sealing parts of the external valve: the contact area between the opening and closing parts and the sealing surface of the valve seat; The matching of packing with valve stem and packing box; The connection between the valve body and the valve cover. The leakage in the previous area is called internal leakage, which is also equivalent to the commonly known loose seal. It will affect the ability of the external valve to block the medium.
For shut-off valves, internal leakage is not allowed. The leakage in the last two places is called external leakage, which means that the medium leaks from inside the valve to outside. External leakage can result in material loss, environmental pollution, and in severe cases, accidents. For flammable, explosive, toxic or radioactive media, external leakage is even more unacceptable, so it is necessary for the external valve to have a reliable sealing function.

It does not require welding when connected to steel pipes, which is beneficial for fire prevention, explosion prevention, and high-altitude operations, and can eliminate the drawbacks caused by careless welding. Weijing Machinery specializes in producing card sleeve connectors. Therefore, it is a relatively reliable connecting component in the piping of automatic control devices in refining, chemical, petroleum, natural gas, food, pharmaceutical, instrumentation and other systems. Suitable for connecting pipelines such as oil, gas, and water.
