The purpose of lifting non-return valves and pipe fastening devices for pressure main hydraulic transport systems (for water pipes, pulse pipelines, oil pipelines, oil product pipelines) is to provide restraints during transient modes and hydraulic shocks in similar systems. The lift of the retractable valve is a hollow connected to a damping device, and the demodulator is made in the form of telescopically interlocked cylinders, the central cylinder of which is rigidly mounted on a hollow chord. The device for fixing the pressure main pipeline, which contains a concrete support, with a part partially recessed into the ground, is different. Its aboveground part is made in the form of horizontal and vertical openings with covers, while in the openings along the perimeter of the pipeline near the opening cover, arcuate bobbins are connected by means of springs, in which damping elements of spherical shape having different masses are freely located.
