Description

Technical Field

[0001] The utility model belongs to the technical field of stop valves, and in particular relates to a stop valve which is easy to open and close. Background Art

[0002] The stop valve, also known as the gate valve, is a forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to not leak. When the medium enters the valve from below the valve disc, the operating force needs to overcome the resistance. The opening and closing parts of the stop valve are plug-shaped valve discs, the sealing surface is a flat surface or a sea cone surface, and the valve disc moves linearly along the center line of the valve seat. The cut-off stop valve is very suitable for cutting, regulating and throttling. Because the valve stem opening or closing stroke of this type of valve is relatively short, and it has a very reliable cutting function, and because the change of the valve seat opening is proportional to the stroke of the valve disc, it is very suitable for regulating the flow.
