Abstract
The utility model belongs to the technical field of pipeline fume exhaust, and particularly relates to a telescopic compensator of a novel structure. The telescopic compensator comprises an outer cylinder (1), an inner cylinder (5), a seal stuffing box (7), a check ring (2), a pressing ring (4) and a fixing support (10), wherein one end of the inner cylinder (5) is sleeved with the outer cylinder (1), and the seal stuffing box (7) is arranged in the gap between the inner cylinder (5) and the outer cylinder (1). The check ring (2) and the pressing ring (4) are arranged at the two ends of the seal stuffing box (7) respectively. Springs (6) are arranged between the pressing ring (4) and the seal stuffing box (7), and the springs (6) are more than one in number and evenly distributed in the gap between the inner cylinder (5) and the outer cylinder (1) along the circumference. By means of the telescopic compensator, the seal stuffing box is evenly pushed by the springs in an operation process of a pipeline all the time, and seal can be guaranteed even if the seal stuffing box is abraded.
Description
Technical field
The utility model belongs to pipeline smoke evacuation technical field, is specifically related to a kind of telescopic compensator of new structure.
Background technique
In the high-temperature low-pressure major diameter fume pipe of industrial enterprise, the line expansion that pipeline compensator is heated and causes with extraction duct must be set between two fixed supports.The pipeline compensator that present most fume pipe uses is: bellow expansion joint and telescopic compensator.The advantage of bellow expansion joint is that sealability is better, and it is convenient to order goods; Shortcoming is that price is higher, and length dimension is larger, the smoke spillage phenomenon can occur.The advantage of telescopic compensator is that compensation rate is large, and cost is low; Shortcoming is the smoke spillage phenomenon to occur.
Two kinds of pipeline compensators all the smoke spillage phenomenon can occur; The leakage that bellow expansion joint in use occurs mainly is corrosion failure; Because the ripple of bellow expansion joint is thinner, the corrosion that is subject to acid in the flue gas is very easily bored a hole; The engineering work load of simultaneously repair and replacement is also larger.During telescopic compensator uses because the wearing and tearing of gland packing box and cause stuffing box to block when being subject to transverse bending, all very easily cause smoke spillage, increase the maintenance engineering amount, caused the working pressure of telescopic compensator not to be higher than 1.6MPa, limited its using scope.
Traditional telescopic compensator structure is seen accompanying drawing 1.It is comprised of inner barrel 5, outer cylinder body 1, back-up ring 2, gland packing box 7, hold-down ring 4, fixed support 10, erosion-resistant refractory lining 9.Utilize the pushing of 4 pairs of gland packing boxes 7 of hold-down ring to play seal action.The wear and leakage phenomenon generally very easily appears in the telescopic compensator of structural type shown in Figure 1 in use for some time.The direction of arrow among Fig. 1 represents the flow direction of flue gas.
The model utility content
The purpose of this utility model proposes a kind of telescopic compensator of new structure just for existing deficiency in the above-mentioned prior art.
The purpose of this utility model can realize by following technique measures:
The telescopic compensator of new structure of the present utility model includes outer cylinder body, inner barrel, gland packing box, back-up ring, hold-down ring and fixed support; One end of described inner barrel is nested with in outer cylinder body, and the binding site of inner barrel and outer cylinder body has the gap, and described gland packing box is arranged in the gap between inner barrel and the outer cylinder body; Be respectively arranged with back-up ring and hold-down ring at the two ends of gland packing box; It is characterized in that: between described hold-down ring and gland packing box, be provided with spring, described spring be a plurality of and be arranged in gap between described inner barrel and the outer cylinder body along even circumferential in; A plurality of described springs all are positioned at spring fixed seat, and described spring fixed seat is connected with described hold-down ring.
The beneficial effects of the utility model are as follows:
The telescopic compensator of a kind of new structure that the utility model proposes makes gland packing box all evenly be subject to all the time the pushing of spring in the conduit running process, even also can guarantee sealing when wearing and tearing appear in gland packing box; The utility model not only good seal performance, compensation rate is large, and price is low, be difficult for leaking, reducing the maintenance engineering amount.
Description of drawings
Fig. 1 is traditional telescopic compensator structure schematic representation.
Fig. 2 is the utility model structural representation.
Fig. 3 is the partial enlarged drawing of A part among Fig. 2.
Among the figure: 1, outer cylinder body, 2, back-up ring, 3, hold-down bolt, 4, hold-down ring, 5, inner barrel, 6, spring, 7, gland packing box, 8, fixing bolt, 9, erosion-resistant refractory lining, 10, fixed support, 11, spring fixed seat.
Embodiment
With specific embodiment the utility model is illustrated by reference to the accompanying drawings:
As shown in Figure 2, a kind of telescopic compensator of new structure, described telescopic compensator includes outer cylinder body 1, inner barrel 5, back-up ring 2, gland packing box 7, hold-down ring 4 and fixed support 10; Described inner barrel 5 has erosion-resistant refractory lining 9, and an end of described inner barrel 5 is nested with in outer cylinder body 1, and described inner barrel 5 is connected the outside by fixed support 10 connections with outer cylinder body.Described inner barrel 5 has the gap and be provided with gland packing box 7 in described gap with the binding site of outer cylinder body 1; Among this embodiment, gland packing box 7 adopts the High Temperature High Pressure graphite packing of high expansivity, has good lubricity, corrosion resistance, sealability.At the two ends of gland packing box 7 back-up ring 2, hold-down ring 4 are set respectively; Back-up ring 2 is welded on the inboard of outer cylinder body 1, play the effect of baffle seal stuffing box 7, prevent that gland packing box 7 from leaking in the inner barrel 5, leave certain interval between back-up ring 2 and the inner barrel 5, convenient telescopic compensator absorbs the length travel of lateral displacement and inner barrel 5.Described hold-down ring 4 is fixedly connected with support 10 by hold-down bolt 4; Said structure is identical with traditional telescopic compensator structure.Between described hold-down ring 4 and gland packing box 7, be provided with spring 6, described spring 6 for a plurality of and be arranged in gap between inner barrel 5 and the outer cylinder body 1 along even circumferential in.With reference to Fig. 3, a plurality of described springs 6 all are positioned at spring fixed seat 11, and described spring fixed seat 11 is connected with described hold-down ring 4.The direction of arrow among Fig. 2 represents the flow direction of flue gas.
The utility model is owing to adopted the sealing material of high expansivity, adopted again the spring pushing, dual measure has guaranteed the sealability of telescopic compensator, and not only good seal performance, compensation rate are large to make it, and price is low, be difficult for leaking, reducing the maintenance engineering amount.
