What Are The Advantages And Characteristics Of The Insulated Ball Valve?

2PC Flanged Ball Valve is a type of valve and is the same type as flange valve. Let's learn about its characteristics.

The insulation ball valve and flange gate valve are valves of the same type. The difference is that its closing piece is a sphere, which rotates around the center line of the valve body to achieve a valve that opens and closes. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. Two-piece ball valves and three-piece ball valves are a new type of valve that has been widely used in recent years. Such valves are generally installed horizontally.

Advantages of insulation ball valves

1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section of the same length.

2. Simple structure, small size and light weight.

3. Tight and reliable. At present, the sealing surface material of ball valves is widely used in plastics, which has good sealing performance and has been widely used in vacuum systems.

4. Easy to operate, quick opening and closing, only need to rotate 90° from full open to full closed, which is convenient for long-distance control.

5. Easy maintenance, simple ball valve structure, generally movable sealing ring, easy to disassemble and replace.

6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when passing through.

7. Wide range of applications, diameters range from a few millimeters to several meters, and can be used from high vacuum to high pressure. When the ball rotates 90 degrees, the inlet and outlet should all present spherical surfaces, thereby cutting off the flow.

Insulated ball valve is a relatively new type of ball valve. It has some advantages of its own structure, such as no friction when switching, the seal is not easy to wear, and the opening and closing torque is small. This can reduce the specifications of the actuator. Equipped with a multi-turn electric actuator, it can achieve the adjustment and strict shutoff of the medium. It is widely used in petroleum, chemical industry, urban water supply and drainage and other working conditions that require strict shutoff.

Features

1. No friction when opening and closing. This function completely solves the problem of traditional [wiki] valves [/wiki] affecting the sealing due to friction between the sealing surfaces.

2. Top-mounted structure. The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce the shutdown of the device and reduce costs.

3. Single valve seat design. Eliminates the problem of abnormal pressure increase in the valve cavity medium affecting the safety of use.

4. Low torque design. The valve stem with a special structural design can be easily opened and closed with a small handle valve.

5. Wedge sealing structure. The valve relies on the mechanical force provided by the valve stem to press the ball wedge onto the valve seat to seal, so that the sealing of the valve is not affected by the change of pipeline pressure difference, and the sealing performance is reliably guaranteed under various working conditions.

6. Self-cleaning structure of the sealing surface. When the ball tilts away from the valve seat, the fluid in the pipeline passes evenly along the ball sealing surface at 360°, which not only eliminates the local scouring of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface, achieving the purpose of self-cleaning.
