Attention to the Ball Check Valve

A variety of check valves have been designed and manufactured to meet the generally increased and more specific requirements. Ball check valve, as one main kind of the check valve, has played an important role at allowing the forward flow and preventing the reverse flow. To be specific, it is widely used for flows or liquid or gas in small capacity. And a wide range of the industrial applications, such as fuel systems and water-pumping systems, have been benefited from the employment of the ball check valve.

Generally speaking, ball check valve has four main parts. They are the valve body, valve ball, valve seat and the conical spring. These four parts cooperate to effectively keep the flow through inside of the body at a consistent volume. Once the spring is compressed to give pressure on the ball, the valve ball would rise up and down in order to provide the path for the flow. Commonly speaking, the spring is able to regulate the entire controlling process in order.

If some outer forces are pushed on the valve, it is likely to result in unpleasant situation. The leakage is the most common failure for this kind valve, which usually occurs at the connection between the ball and the valve seat. Besides, the leakage may be caused by the excessive tightening of the threaded connections. Whatever, the leakage would greatly reduce the industrial performance. As a result, it is wise to solve the problem by taking some practical measures. The adoption of the manufacturing materials which can withstand the wear of corrosive forces does great favors. What else, the regular and consistent inspection and analysis for the whole equipment is quite necessary. For example, it is useful to prevent the liquids or gases containing any electricity from being passed through. Otherwise, the efficiency and accuracy of the ball check valve would be greatly reduced.
