Structure characteristics of eccentric ball valve
Here is Structure characteristics of
① The eccentric ball valve is a top mounted structure: the valve installed on the pipeline can be directly inspected and maintained online, which can effectively reduce device shutdown and reduce costs.
② The eccentric ball valve is a single seat design, which eliminates the problem that the medium in the valve cavity affects the use safety due to abnormal pressure rise.
③ Low torque design: the valve rod with special structure design can be opened and closed easily with a small handle valve.
④ Friction free opening and closing: this function completely solves the problem that the traditional valve seals are affected by friction between sealing faces.
⑤ Wedge sealing structure: the valve is sealed by pressing the ball wedge onto the valve seat with the mechanical force provided by the valve stem, so that the sealing performance 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 ball valve: when the ball is tilted away from the valve seat, the fluid in the pipeline passes through the sealing surface of the ball at 360 ° evenly, which not only eliminates the local scouring of the valve seat by high-speed fluid, but also washes away the accumulation on the sealing surface, so as to achieve the purpose of self-cleaning.
