Pneumatic ball valve production process

Pneumatic ball valve is a commonly used mechanical equipment, with good valve sealing, long service life, corrosion resistance and other characteristics. The production process of pneumatic ball valve is very important, it directly affects the quality and performance of pneumatic ball valve. The following will give you a detailed introduction to the production process of pneumatic ball valves.

First, processing ball

Pneumatic ball valve sphere is one of its key components, its production is the most important of the entire production process. In general, the processing of the ball body is divided into the following steps:

1, steel quality inspection

Before the sphere processing, the steel needs to be quality inspection. Generally need the chemical composition of steel, mechanical properties and other aspects of the inspection to ensure that the quality of steel in line with relevant standards.

2, forging sphere

Forging is the most critical step in the ball processing process, through the forging can make the composition of steel uniform, improve its mechanical properties. Forging generally need to use the forging machine, the steel will be deformed to become the predecessor of the sphere.

3、Sphere molding

After forging the sphere is just a simple spherical billet, but also need to be further processed into the final sphere. Sphere molding requires the use of special ball molding machinery, the spherical billet will be further pressed into the precise size of the sphere.

4、Finish processing of the sphere

After the ball after molding, the surface of the ball there will be some irregular high and low bumps. In order to ensure the dimensional accuracy and surface flatness of the sphere, the sphere needs to be finished. Generally need to use CNC machining centers and other high-precision equipment, turning, grinding and other processing of the sphere.

Second, assembly pneumatic ball valve

After the above steps of the sphere, before sending to the assembly workshop also needs to be sandblasted, cleaned, polished and other processing, ready for assembly. Specific assembly process is as follows:

1, decomposition of the valve body

First of all, the valve body needs to be disassembled to clean up the debris and dirt inside the valve. Check whether the valve core, seals and other parts are damaged or worn.

2、Installation of sealing ring

Install the sealing ring at the interface between the valve body and the valve core to ensure good sealing performance. The sealing ring needs to be made of highly wear-resistant and corrosion-resistant materials.

3、Install the spool

Install the spool into the valve body, and check whether the spool can move freely to ensure that the spool and the sealing ring are closely matched.

4、Installation of ball

Install the ball onto the seat of the valve body, make sure the ball can rotate freely and have good contact with the seat.

5、Installation of connectors

Install the connectors to connect the pneumatic actuator and the valve to ensure that the pneumatic ball valve can operate normally.

6、Test the valve

Finally need to test the pneumatic ball valve, check the valve sealing, rotation performance and other indicators to meet the requirements.

The above is the production process of pneumatic ball valves, through the precise and scientific production process, can ensure the quality and performance of pneumatic ball valves.
