The pressure self sealing gate valve adopts a sealing structure that combines packing external sealing and internal pressure self sealing at the valve stem sealing, ensuring that the medium does not leak. The outer seal of the valve stem is made of polytetrafluoroethylene or O-ring packing, which is pressed tightly with a packing gland. Under the action of medium pressure, an upward pressure is generated. The higher the medium pressure, the greater the sealing force. This structure is suitable for high-pressure media.
