Abstract
The utility model discloses a nonmetal compensator with large radial compensation, which comprises a connecting pipe, a sheath, a bolt, a nut, a nonmetal thin-walled sleeve, a small-diameter ring sleeve, a heat insulation material and a large-diameter ring sleeve. Two ends of the nonmetal thin-walled sleeve are connected with a flange of the connecting pipe through the sheath, the bolt and the nut to form a compensating structure, one end of the small-diameter ring sleeve and one end of the large-diameter ring sleeve, which contact with the end surface of the flange of the connecting pipe, are respectively provided with flanges, the small-diameter ring sleeve and the large-diameter ring sleeve are in clearance sleeve with the end surface of the flange of the connecting pipe, a left limiting ring and a right limiting ring are respectively fixedly connected onto a flange end surface opposite to the connecting pipe, and are respectively provided with axial concave ring slots opposite to the flange end surface fixedly connected with the left limiting ring and the right limiting ring, an outwards turned barrel opening at the periphery of the flange of the small-diameter ring sleeve is in clearance sleeve in the axial concave ring slot of the left limiting ring, and an outwards turned barrel opening at the periphery of the flange of the large-diameter ring sleeve is in clearance sleeve in the axial concave ring slot of the right limiting ring. The nonmetal compensator can realize larger radial compensation and guarantee heat insulation effect.
Description
Technical field
The utility model relates to a kind of pipe safety device, and specifically, the utility model relates to a kind of non-metal compensator that is adapted at using in the high temperature media.
Background technique
Non-metal compensator is widely used in the high temperature smoke discharge pipe roads such as thermoelectricity plant, Iron And Steel Plant, smelter, the non-metal compensator of prior art comprises adapter, nonmetal thin-walled cover, path ring set, thermal insulating material and big footpath ring set, nonmetal thin-walled cover connects two ends and takes over the formation collocation structure, path ring set, ring set gap, big footpath fit between two pipe nipples, path ring set, big footpath ring set are fixedlyed connected with the adapter at two ends respectively, and thermal insulating material is built in adapter, path ring set, big footpath ring set and nonmetal thin-walled and overlaps in the cavity that forms.In the prior art, gap between path ring set, the big footpath ring set has determined the radial compensation amount of compensator, because reasons in structure, gap between path ring set, the big footpath ring set can not very big (less than 50mm), because if the gap is very big, then thermal insulating material can drop out from bigger gap location, so just reduced the storage of thermal insulating material, influence the heat insulation and preservation effect of compensator, thereby shortened the working life that is applied to the non-metal compensator in the high-temperature flue gas blowdown piping, so the non-metal compensator radial compensation amount of prior art is less.In high temperature smoke discharge pipe roads such as thermoelectricity plant, Iron And Steel Plant, smelter, because medium is a high-temperature flue gas, the displacement that pipeline produces is bigger, and therefore required radial compensation amount is bigger, and obviously the non-metal compensator of prior art can't satisfy its compensation requirement.
Summary of the invention
The utility model is at the deficiencies in the prior art, and proposition can realize bigger radial compensation, can guarantee the big radial compensation amount non-metal compensator of heat insulation and preservation effect again.
The utility model is achieved through the following technical solutions technical goal.
Big radial compensation amount non-metal compensator, it comprises adapter, sheath, bolt, nut, nonmetal thin-walled cover, path ring set, thermal insulating material and big footpath ring set; Axially the near-end of two relative adapters is provided with flange, and described nonmetal thin-walled cover two ends connect the flange of taking over by sheath, bolt, nut and constitute collocation structure; The end that the path ring set of gap fit, big footpath ring set contact with the pipe connecting flange end face between the described pipe connecting flange end face respectively is provided with flange separately; Described thermal insulating material is built in the cavity of adapter, path ring set, big footpath ring set and the formation of nonmetal thin-walled cover; Its improvements are: also comprise the left limit ring, the right limit ring that are fixedly connected on the relative end face of flange of two pipe nipples; Described left limit ring, right limit ring are respectively equipped with the end face of flange relative axial spill annular groove fixedly connected with, the nozzle gap that path ring set flange periphery turns up is linked in the left limit annulate shaft in the spill annular groove, and the nozzle gap that big footpath ring set flange periphery turns up is linked in the right limit annulate shaft in the spill annular groove.
The utility model compared with prior art has following good effect:
1. the radial compensation amount of compensator equals nozzle that path ring set flange periphery turns up in the gap sum of the left limit annulate shaft nozzle that radial clearance, big footpath ring set flange periphery turn up in the spill annular groove at right limit annulate shaft radial clearance and path ring set, big footpath ring set fit in the spill annular groove, can realize bigger radial compensation.
2. the gap of path ring set, big footpath ring set fit is less, thermal insulating material is difficult for dropping out from the gap location between path ring set, the big footpath ring set, guaranteed the storage of thermal insulating material, guarantee heat insulation and preservation effect, thereby guaranteed the working life of the non-metal compensator installed in the high-temperature flue gas blowdown piping.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
Big radial compensation amount non-metal compensator shown in the accompanying drawing 1, it comprises adapter 1, sheath 2, bolt 3, nut 4, left limit ring 5, nonmetal thin-walled cover 6, path ring set 7, thermal insulating material 8, big footpath ring set 9 and right limit ring 10; The near-end of two axially relative adapters 1 is provided with flange, and described nonmetal thin-walled overlaps 6 two ends and constitutes collocation structure by the flange that sheath 2, bolt 3, nut 4 connect adapter 1; Take over gap fit between 1 end face of flange path ring set 7, big footpath ring set 9 be provided with flange separately with the end that adapter 1 end face of flange contacts; Thermal insulating material 8 is built in the cavitys of adapter 1, path ring set 7, big footpath ring set 9 and 6 formation of nonmetal thin-walled cover; On the relative end face of flange of two pipe nipples 1, fixedly connected left limit ring 5, right limit ring 10 respectively; Described left limit ring 5, right limit ring 10 are respectively equipped with the end face of flange relative axial spill annular groove fixedly connected with, the nozzle gap that path ring set 7 flange peripheries turn up is linked in the left limit ring 5 axial spill annular grooves, and the nozzle gap that big footpath ring set 9 flange peripheries turn up is linked in the right limit ring 10 axial spill annular grooves.
The utility model in actual use, the nozzle that path ring set 7 flange peripheries turn up can move in left limit ring 5 axial spill annular grooves, the nozzle that big footpath ring set 9 flange peripheries turn up can move in right limit ring 10 axial spill annular grooves, therefore the radial compensation amount of compensator can be bigger, and because path ring set 7, the gap less (less than 50mm) of big footpath ring set 9 fits, thermal insulating material 8 is difficult for from path ring set 7, gap location between the ring set 9 of big footpath drops out, guaranteed the storage of thermal insulating material 8, thereby guaranteed heat insulation and preservation effect, guaranteed the working life of the non-metal compensator installed in the high-temperature flue gas blowdown piping.
