The working principle of the ball valve is by rotating the valve to make the valve unblocked or blocked. Ball valve switch is light, small size, can be made of large diameter, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical surface is often closed, easy to be media erosion, widely used in various industries. Ball valve is divided into two categories, one floating ball, the second is fixed ball. Ball valve is widely used in irrigation systems, mainly used in the branch pipe imports. Ball valve structure is simple, small size, resistance to water flow is also small, the disadvantage is that open or close too fast, will produce water hammer in the pipe (water pipe pressure suddenly changes in the pressure will rise). Therefore, the main pipe should not be used on the ball valve can be used in the dry, branch or on the end for flushing purposes, flushing sewage effect. Ball valve with O-ball valve and V-ball valve points. O-type ball valve with floating structure, the core is precision castings, the appearance of hard chrome plated, seat made of reinforced PTFE material, the flow channel mouth and pipe the same caliber, great flow resistance, flow resistance is very small, when closed Leakage, the general use of the switch valve, especially for high viscosity, fiber, granular media; V-type ball valve with a fixed structure, the core opened with a V-shaped incision, proportional control can be achieved, the flow characteristics of approximately equal percentage. Depending on the process equipment can be used pneumatic or electric actuator, respectively, composed of pneumatic ball valve and electric ball valve, pneumatic valve to achieve proportional control to be equipped with valve positioner, electric ball valve to be proportional to be adjusted to be selected electronic electric actuator or Servo amplifier and so on.
