| description | The utility model discloses an automatic super-normal flow control stop valve which comprises a valve body, a piston, a spring, a valve body inflow end and a valve body outflow end. The piston is shaped like a conical body. The rear portion of the piston is provided with a cylinder. The cylinder is sleeved with a spring. The portion, located on the rear side of the conical body of the piston, of a valve body pipe wall is provided with a conical face of the same caliber. A cylindrical valve body pipe wall is located behind the conical face of the valve body pipe wall. The cylinder of the piston penetrates through the cylindrical valve body pipe wall and is fixed into the cylindrical valve body pipe wall through a baffle at the rear end. The spring is located at the portion, between the conical body of the piston and the cylindrical valve body pipe wall, of the cylinder of the piston. A gap between the piston and the valve body pipe wall serves as a front section flow-through passageway. A rear section flow-through passageway is arranged on the outer side of the cylindrical valve body pipe wall. A valve body pipe threaded section on one side of the conical body of the piston serves as the valve body inflow end. A valve body pipe threaded section on one side of the cylinder of the piston serves as the valve body outflow end. By means of the automatic super-normal flow control stop valve, the technical problem that a valve is automatically controlled to be closed when abnormal flow appears in a pipeline device for liquid, gas and the like can be solved. |
