Ball Valve

Ball valve is a valve that uses a ball as a means of cutting off or controlling fluid channels. The ball can rotate during valve operation to achieve flow control. Ball valves are widely used in industries such as petrochemical, urban construction, water supply and drainage, metallurgy, papermaking, pharmaceuticals, and food.

Ball valves can be divided into two types according to their structure: floating ball valves and fixed ball valves. The ball valve floats in the medium and balances with the valve seat pressure to achieve cut-off; The fixed ball valve is closely matched with the valve seat, allowing the ball to rotate and controlling the flow rate of the medium during operation. According to different materials, ball valves can also be divided into cast steel ball valves, stainless steel ball valves, cast iron ball valves, copper ball valves, etc.

The advantages of ball valves are mainly reflected in the following aspects:

1. The operation is simple and fast, and generally only needs to be rotated 90 degrees to achieve opening and closing;

2. Good sealing performance, the switching of the ball can ensure that the valve instantly cuts off the medium and is not prone to leakage;

3. The structure is simple and easy to maintain. Ball valve maintenance usually only requires disassembling the valve body and replacing parts;

4. Strong flow capacity, the sphere itself has no structural limitations such as support rods, and the flow resistance of the medium is small, resulting in strong flow capacity.

Ball valves have a wide range of applications in many fields. Let's take a look at which fields ball valves play an important role.

1. Petrochemical: Ball valves are widely used in instruments and pipelines, mainly for control in petrochemical production.

2. Paper making, food, and pharmaceutical industries: Due to the fact that the medium in these industries is generally liquid, the characteristics of good sealing performance and high cleanliness of ball valves make them key pipeline equipment in these enterprises.

3. Water supply and drainage field: Ball valves play a very important role in the treatment of urban water supply and factory drainage, because the valve body has good sealing performance, high durability, and can withstand the impact of a large amount of media.

4. Boiler room and heating pipe network field: Ball valves can be used for various automatic and manual valves to control the flow rate in the heating system cycle.

In short, ball valves have the advantages of simple structure, easy operation, easy maintenance, wide caliber range, high flow control accuracy, and wide application fields, making them one of the important fluid control equipment.
