Eccentric Floating Ball Valve,
Hemispherical Floating Ball Valve,
Lightweight Ductile Iron Flange Ball Valve
The valve can be used to prevent the medium from adverse current in any pipeline system.
The valve is unblocked or blocked by rotating the valve chain. The ball valve has the advantages of light switch and small volume. It can be made into a large diameter, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are often closed, which is not easy to be eroded by the medium. It has been widely used in various industries
1. Top mounted type: it is mainly aimed at the medium with serious erosion and wear. The top mounted structure is very convenient for the replacement and maintenance of the damaged opening and closing parts. There is no need to remove the whole valve from the pipeline, which greatly saves the maintenance time and cost.
2. Side mounted type: the side mounted type has compact structure and light valve weight. It is suitable for occasions requiring valve installation space.
① The eccentric hemispherical valve is a 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 the cost.
② Eccentric hemispherical valve is a single seat design. The problem that the medium in the cavity of the valve affects the use safety due to abnormal pressure rise is eliminated.
③ Low torque design. The valve stem with special structural design can be opened and closed easily with only a small handle.
④ There is no friction between opening and closing. This function completely solves the problem that the sealing of traditional [wiki] valve [/ wiki] is affected by mutual friction between sealing surfaces.
⑤ Wedge seal structure. The valve is sealed by pressing the ball wedge onto the valve seat by the mechanical force provided by the valve stem, so that the tightness of the valve is not affected by the change of pipeline differential pressure, and the sealing performance is reliably guaranteed under various working conditions.
⑥ Self cleaning structure of sealing surface of eccentric hemispherical valve. When the ball is tilted away from the valve seat, the fluid in the pipeline passes through 360 ° evenly along the sealing surface of the ball, 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, so as to achieve the purpose of self-cleaning
1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section with the same length.
2. Simple structure, small volume and light weight.
3. It is tight and reliable. The sealing surface of the ball valve is widely made of plastic with good sealing performance. It has also been widely used in the vacuum system.
4. It is easy to operate and open and close quickly. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control.
5. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.
6. When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium. When the medium passes through, it will not cause the erosion of the valve sealing surface.
7. It has a wide range of applications, ranging from small diameter to a few millimeters and large diameter to a few meters. It can be applied from high vacuum to high pressure. When the ball rotates for 90 degrees, the inlet and outlet shall be spherical, so as to cut off the flow.
