The utility model at more than 400Mpa, can ensure permanent static seal performance, and volume is little, lightweight, without the need to by large-scale pretensioning device, dependence pressure itself pretension, improve stock utilization, cost is low, equipment precision is high, stabilization of equipment performance good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The ultrahigh pressure conical surface seals firmly from pretension accumulator, comprises accumulator cylindrical shell 9, accumulator water pipe 5, Cuprum alloy stuffing box gland 8, pre-load nut 6, end nut 7 and pre-tightening apparatus.Described accumulator cylindrical shell 9 two ends are all equiped with the accumulator water pipe 5 of same structure, the accumulator water pipe 5 at two ends is all set with Cuprum alloy stuffing box gland 8 and end nut 7, described end nut 7 is threaded with accumulator cylindrical shell 9, Cuprum alloy stuffing box gland 8 and accumulator water pipe 5 are located and be supported on accumulator cylindrical shell 9 two ends with pretension, pre-load nut 6 is screwed on accumulator water pipe 5 and compresses end nut 7.Described Cuprum alloy stuffing box gland 8 one end be sleeved on accumulator water pipe 5 is provided with Cuprum alloy stuffing box gland and accumulator water pipe and is firmly sealed and matched the conical surface 11, and it coordinates conical surface surface roughness >0.4UM.Cuprum alloy stuffing box gland 8 cylindrical is provided with Cuprum alloy stuffing box gland and accumulator cylindrical shell and is firmly sealed and matched cylndrical surface 12, and it coordinates conical surface to be snug sliding fit, coordinates cylindrical face surface roughness >0.4UM.Adopt the pre-tightening apparatus leaned in accumulator body end surface, this pre-tightening apparatus is made up of pull bar 1, pull-rod nut 2, stop sleeve 3, locking nut 4.Pull bar 1 is through stop sleeve 3, accumulator cylindrical shell 9 end face is close in stop sleeve 3 one end, simultaneously pull bar 1 is threaded accumulator water pipe 5, load spanner mouth 13 with spanner and limit pull bar radial rotary, and lock pull bar with locking nut 4, pull-rod nut 2 is screwed in and is positioned on stop sleeve 3 outer end pull bar 1, and stop sleeve 3 is pressed on accumulator cylindrical shell 9 end face.Make the stressed tensioner of Cuprum alloy stuffing box gland 8 in accumulator cylindrical shell 9 one end, reach Cuprum alloy stuffing box gland and the accumulator water pipe conical surface 11, Cuprum alloy stuffing box gland and the accumulator cylindrical shell cylndrical surface 12 that is firmly sealed and matched that is firmly sealed and matched and compress hard sealing.
Working principle
Strengthen gradually with open-end wrench and be applied to screw-down torque on pull-rod nut 2, accumulator water pipe 5 axle center is impelled to stretch, the accumulator water pipe conical surface compresses Cuprum alloy stuffing box gland, the stressed rear compressive strain tensioner of Cuprum alloy stuffing box gland is in accumulator cylindrical shell one end, tighten pre-load nut 6, unscrew pull-rod nut 2, remove pull bar 1, locking nut 4, stop sleeve 3.Thus reach Cuprum alloy cover with accumulator cylinder, accumulator water pipe sealing.To lock accumulator water pipe 5 the other end with end socket 10 again, from the other end input high pressure water of accumulator water pipe, increase the pressure of input high pressure water gradually, the stressed increase of thick head end of accumulator water pipe, coordinate tightr with Cuprum alloy stuffing box gland, Cuprum alloy stuffing box gland 8 is by the extrusion-deformation supercharging tensioner accumulator barrel of accumulator water pipe.Meanwhile, accumulator water pipe axial tension, tightens pre-load nut 6, and reaching need not pretensioning device, relies on high pressure water to apply pretightening force, reaches the object of sealing, and apply to be greater than the pretightening force using pressure 20%, the equipment long-term stability of guarantee uses.
The Cuprum alloy stuffing box gland of varying strength, tapering is selected according to the pressure rating of distinct device and accumulator barrel diameter.The conical surface firmly seals and can reach stable using effect from the structure of pretension accumulator at whole different pressures rate range, meets national energy-saving, subtracts consumption, the promotion of environmental protection novel economizer.
