A pipe bursting shutoff valve comprises a valve body which is arranged on a pipe body and communicated with the inner portion of the pipe body. The pipe bursting shutoff valve further comprises a control cavity, a valve shaft, a first elastic component, a diaphragm piston and a valve disc, the first elastic component, the diaphragm piston and the valve disc are arranged on the valve shaft in sequence, the control cavity is connected with the valve body, the valve shaft penetrates through the control cavity to enter the valve body, the diaphragm piston is arranged inside the control cavity, the control cavity is in rigid connection with the diaphragm piston, the control cavity is divided into an independent upper chamber and an independent lower chamber, the valve disc is arranged inside the valve body, the lower chamber is communicated with the pipe body through a lower chamber through pipe, the first elastic component can drive the valve shaft to move along the central line of the valve shaft after being stressed and deformed, and the movement of the valve shaft can enable the diaphragm piston to be deformed in the control cavity to change the size of the upper chamber and the size of the lower chamber, and meanwhile can drive the valve disc to move in the valve body and the pipe body. The pipe bursting shutoff valve has the advantages of being capable of adapting to the normal change of pressure in a pipeline and being mounted by adopting any angle.
