The device is applied to the construction process, firstly the device is assembled and installed at the source end of an operation pipeline, so that the pipeline controlled by a worker is led out from the end of a flow controller 5, under normal work, an elastic water bag 403 in a pressurizing expansion mechanism 4 is in a normal state, a flow meter 10 records flow data normally, when the pressure and the flow of water or slurry and the like are increased suddenly, the volume of the elastic water bag 403 is increased, a thimble 15 is caused to move upwards, the thimble 15 drives a first control swing rod 2 and a second control swing rod sleeved with a constraint angle bracket 20 to move upwards in the upward movement process, the other end of the first control swing rod 2 generates a lever principle through a fixed pin on a right-angle fixed seat 6 to move downwards, and drives a push-pull rod 8 and a control water baffle plate 501 on the flow controller 5 to move vertically downwards in the downward movement process, so that the inner diameter cross section of the flow controller 5 is reduced or blocked, thereby automatically controlling and adjusting the flow and the pressure.
When the pressure is normal, the volume of the elastic water drum 403 is reduced, and meanwhile, the thimble 15 is caused to move downwards, so that the first control swing rod 2 loses the control jacking force, the tension spring 25 can pull the left end of the first control swing rod 2 to move downwards, the fixing pin on the fixed seat 6 at the other end of the first control swing rod 2 passes through the right angle barrel generates a lever principle to enable the first control swing rod to move upwards, and the push-pull rod 8 and the control water baffle 501 on the flow controller 5 are driven to vertically move upwards in the upward movement process, so that the inner diameter cross section of the flow controller 5 is enlarged, and the flow of the pipeline is recovered to be.
