characteristic:
Stop valve refers to the valve whose closing part (disc) moves along the center line of the valve seat. According to this moving form of the disc, the change of the valve seat opening is in direct proportion to the disc stroke. Because the valve stem opening or closing stroke of this kind of valve is relatively short, and has a very reliable cut-off function, and because the change of the valve seat opening is in direct proportion to the stroke of the valve disc, it is very suitable for the regulation of flow. Therefore, this type of valve is very suitable for cutting off or regulating and throttling.
advantage:
(1) in the process of opening and closing, the friction between the valve disc and the sealing surface of the valve body is smaller than that of the gate valve, so it is wear-resistant
(2) the opening height is generally only L / 4 of the valve seat channel diameter, so it is much smaller than the gate valve.
(3) there is usually only one sealing surface on the valve body and disc, so the manufacturing process is relatively good and convenient for maintenance. However, the shortcomings of the stop valve can not be ignored. Its disadvantage is that the flow resistance coefficient is relatively large, so it causes pressure loss, especially in hydraulic devices, which is particularly obvious.
