Copper Ball Valves

Copper ball valves are a common spherical stop valve widely used in industrial pipeline systems.

They have the advantages of simple structure, good sealing performance, and easy operation. They are suitable for a variety of media, such as water, gas, steam, oil, and chemicals. This article will comprehensively introduce copper ball valves from the following aspects.

1. Structure and principle of copper ball valve

It is mainly composed of a ball, valve seat, valve stem, handle, flange, etc. The ball is a spherical structure with a hole in the middle, and the diameter is the same as the diameter of the pipe. When the handle rotates, the valve stem transmits force to rotate the ball, thereby realizing switch control.

The valve seat is the sealing component between the ball and the pipe, usually made of corrosion-resistant materials such as polytetrafluoroethylene. In the closed state, the ball is isolated from the pipe by the valve seat, thereby completely cutting off the fluid. In the open state, the gap between the ball and the valve seat forms a channel, allowing the fluid to pass through.

2. Advantages and disadvantages of copper ball valve

Advantages:

(1) Good sealing performance: The elastic sealing structure of the ball and the valve seat is adopted, which has good sealing performance and can withstand high pressure and high temperature. (2) Easy to operate: The switch control is achieved by rotating the handle, which is simple and convenient to operate.

(3) Large diameter: The diameter range is wide and can meet the needs of different pipe diameters.

(4) Strong corrosion resistance: It can be made of corrosion-resistant materials and is suitable for various media.

(5) Long life: Due to its simple structure and few parts, it has a long life.

Disadvantages:

(1) High price: Compared with other stop valves, the price of copper ball valves is higher.

(2) Difficult to maintain: Due to the complex internal structure of copper ball valves, maintenance is difficult.

III. Application fields of copper ball valves

Applicable to various media, including water, gas, steam, oil, chemicals, etc. It has a wide range of diameters and is usually used for fluid control in industrial pipeline systems.

IV. Installation and maintenance of copper ball valves

Installation:

(1) Before installation, check whether the copper ball valve's model, specification, and material meet the requirements.

(2) During the installation process, pay attention to the direction and flow direction of the copper ball valve to avoid reverse flow.

(3) When connecting the copper ball valve to the pipeline, attention should be paid to the tightening strength and sealing performance.

Maintenance:

(1) Regularly check its sealing performance and operating performance.

(2) Clean the dirt and sediment inside it to maintain the cleanliness of the inside of the valve.

(3) Replace damaged parts and lubricants.

V. Conclusion

In summary, as a common stop valve, the copper ball valve has the advantages of simple structure, good sealing performance, and easy operation, and is suitable for various media. During the installation and maintenance process, some details need to be paid attention to ensure the normal operation of the copper ball valve.
