balll valve introduction
A ball Valves is normally used to control the flow. The party fielded a ball valve is a spherical disc, which controls the flow through them. And there is a hole or port in the center of the sphere. Indeed, while both the long end of the valve. If there are two ends of the flow valve on the line. And when the valve is closed, the hole is blocked perpendicular to the ends of the valve and flow. During this process, the handle or lever of great benefit in line with the position that the port is to be done.
Based on specific requirements and ease of use of ball Valve in the industry largely due to the versatility and range of pressures and temperatures of support. Sizes and in general from 0.5 cm to 30 cm. In general, materials for the body of ball valves, metal, plastic or metal with a ceramic center. The ball and often cover for increased durability and valve malfunction in case of chrome power.
In order to meet specific requirements of industry, ball valves are classified into different types. From the standpoint of body shapes, only done in three parts, with accommodation in two parts, the first entry, and soldiers. I must say that the classification is based on the number of valve parts. Although there are several types of valves, the operation is similar. And from the standpoint of the mechanism of the ball was, there are many styles. Are reduced to the entire port, scion of the ball valve V-port and the valve cavity filling. Moreover, manual valves closed quickly. And some are ball valves with pneumatic actuator that can be operated or equipped. These valves are usually equipped with a positioner. In this way, becomes for them according to the control signal to the actuator position and valve opening easy. For example, ball valves are usually multi-port 4-way or more. They are available in the market. And by the way of air motors from forward to reverse, turning the operating leverage of a single 4-way valve is made. What else, one piece ball valves are almost always associated with reduced shipping costs, which are relatively inexpensive and often disposable. And two piece ball Valves are usually easily reduced (or standard) was wearing, it can be disposable or repaired.
