Pneumatic ball valve working principle and installation precautions
In the rapid development of industrialization today, the use of valves not only helps companies in the various pipelines to adjust the work more convenient, but also makes the company to ensure the safety of life of personnel, improve the operating efficiency, due to the advantages of the valve, at present, in our country Valves are commonly used in all walks of life. Pneumatic ball valve is one of the widely used types of valves. So, what is the working principle of pneumatic ball valve? What should we pay attention to when installing pneumatic ball valve? Let's take a look together.
First, the working principle of pneumatic ball valve
Pneumatic ball valve is a special device combined with pneumatic actuator and ball valve. Under normal circumstances, pneumatic ball valve must be used in combination with other accessories, such as control box, limit switch, solenoid valve, etc. The long-distance control and local control activities save the manpower and material resources for the company and ensure the safety and practicality of construction operations.
The working principle of the pneumatic ball valve is: the use of pneumatic actuator operation, that is, after the gas source is rotated 90 degrees, it can produce a small torque, so as to achieve the purpose of close. Because the valve body cavity of the pneumatic ball valve is equal, it has a very small resistance path for the medium. In general, ball valves are best used as switches. Because the ball valve is characterized by a compact structure, operation and maintenance are very easy, and it can be applied to general working media. Therefore, the range of applications is extremely wide.
Second, the installation of pneumatic ball valve should pay attention to matters
1. Before installation, remove the protective cover of the two sections of the pneumatic ball valve so that it can be fully opened and cleaned. Then, test the signal to avoid affecting the valve's use.
2. Before the pipeline and the pneumatic ball valve are connected, some residual substances that may be present in the bite pipeline are effectively cleaned to avoid damage to the valve seat by impurities. When installing, the hoisting point for hoisting should be the executing part of the valve body, otherwise the actuator will be damaged.
3, pay attention to maintain the vertical installation of the valve, so as to ensure the use of results.
By understanding the working principle of the pneumatic ball valve and the precautions during installation, it can be ensured that the pneumatic ball valve can play a good effect in industrial operations.
