What is the difference between a half ball valve and a full ball valve? Now let's take a brief analysis.

People often ask me to sanitary ball valve, but it is not clear that the sanitary ball valve has half and full package points. The reason why the sanitary valve is called sanitary is largely because its internal structure is sanitary. What is hygiene? To be understood separately, Wei means protection and maintenance, and Sheng refers to health and safety.

Therefore, the sanitary ball valve should be high clean, there is no dead Angle, not because of the residue of the medium, and there is the danger of bacteria. The comparison between the semi-packaged structure and the full-packaged structure is clear. Full package and half package, refers to the ball valve sealing gasket coverage of the ball is different,

The higher the degree of coating, the smaller the space of the valve chamber, and the valve chamber has become a factor of fluid instability. Strictly speaking, half ball valves can not be called sanitary valves. Because there are residues, dead corners, there are certain limitations in the use of water and gas. The all-inclusive ball valve, the ball holder adopts the all-inclusive design, and meets the CIP/SIP sterilization and cleaning requirements, which well solves the problem of material remaining in the valve chamber, so the all-inclusive ball valve is also known as the non-retention ball valve.

Speaking of the valve core seal (seat seal) of the ball valve, PTFE (polytetrafluoroethylene) material is generally used, and the cost is high. The price difference between full-package ball valves and half-package ball valves is reflected here. Some ball valves in circulation. Their seats are thinner than half a bag, shaped like flat pads, like the thickness of a coin. With the increase of the number of valve opening and closing in China, subject to the accuracy of processing technology, the deformation of the valve seat and seal will significantly increase, and the internal leakage of the ball valve is a large probability. Some simply use thick silicone gaskets, and the ball becomes a float ball, which shows its wear resistance.

How does the all-inclusive ball valve work? Now let's take a brief analysis.

The ball valve is an innovative high-tech energy-saving commodity, and its promotion and application is conducive to saving steel, improving production and processing efficiency, and reducing energy consumption. Can be widely used for gas, liquid, steam, oil and other corrosive media of the pipeline system automation management control. It is a relatively new type of ball valve, which has some advantages of its own construction, such as frictionless switching, sealing is not easy to wear, and small opening and closing torque. This reduces the size of the actuator provided. The working principle of the ball valve is to make the valve open or blocked by rotating the valve. Ball valve switch light, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and sphere are often in a closed state, not easy to be washed by the medium, in various industries have been widely used.

Ball valve and plug valve are the same type of valve, the difference is that its closing part is a ball, the ball rotates around the center line of the valve body to achieve the opening and closing of a valve. Ball valves are mainly used in pipelines to cut off fast, distribute and change the flow direction of the medium. Ball valve is a widely used new type of valve. The principle of the all-inclusive ball valve only needs to rotate 90 degrees of operation and a small torque to close tightly. The equal body cavity provides the medium with a small resistance and straight flow path.
