Abstract
The utility model discloses a wellhead stop valve. The stop valve comprises a bonnet, a valve part, a valve rod in the valve part, a sealing gasket and a bonnet which are sleeved on the valve rod. The top end of the valve rod is hemispherical, a pentagonal unsealing groove is formed in the center of the hemisphere, the bonnet comprises an axial protrusion portion towards the valve rod, a rubber groove is formed in the valve rod, and O-shaped sealing rings are arranged at the two ends of the rubber groove. A tightening sheet is arranged at the tail end of the bonnet and is connected onto the valve part inner wall, the top end of the valve rod is connected with the protrusion portion, a through hole of the valve part is clamped with the tail end of the valve rod, and a connecting valve is arranged at the tail end of the valve rod. The wellhead stop valve is simple in structure and convenient to use; opening and closing are performed through special tools, so that oil valve stealing incidents and environmental pollution are prevented effectively, and management is facilitated.
