Abstract
The utility model discloses a Rockwell pipeline compensator which is applied to the connection of seamed or seamless steel pipes in fuel electric plants and mines as well as such industries as petroleum, chemical engineering, smelting and coal washing. The pipeline compensator comprises a pair of gland flanges, seal rings, an outer ring, pull rods and adjusting nuts, wherein the outer ring is sleeved on a left pipeline and a right pipeline, the pair of gland flanges are fixed on the two sides of the outer ring through the pull rods and the adjusting nuts which are uniformly distributed, and the seal rings are arranged between the outer ring and the gland flanges. The double-end self-energized elastic packing rings are adopted in the utility model for sealing, thereby achieving perfect andreliable sealing performance and eliminating the leaking phenomenon of the original seal rings caused by the vibrations of the pipelines as the seal rings are compressed tightly after being fastened.With the service life being prolonged by 3-4 times, the pipeline compensator has the characteristics of convenient installation, maintenance and replacement, and can be applied to the transmission ofvarious solid particles containing dusts, ashes, etc.
Description
Technical field:
The utility model relates to a kind of pipeline compensator, relates in particular to be used in the bushing type pipeline compensator that connects between seam or the seamless steel pipe.
Background technique:
In the thermal power plant, oil, chemical industry, smelt, the mine, industries such as coal washing adopt various have seam or seamless steel pipes, because the specification length of steel pipe is standard, usually need to weld the length that guarantees pipeline, but factor affecting such as pipeline is in use expanded with heat and contract with cold, the impossible unconfined welding of pipeline, the phenomenon of expanding with heat and contract with cold of must the pipe laying compensator when pipeline reaches certain-length eliminating pipeline, pipeline compensator in the market mainly contains bushing type, bellow type and ball compensator etc. are several, bellow type compensator technology is comparatively advanced, but there is the manufacturing process complexity, cost of production is higher, the defective that compensation rate is little is not suitable for containing powder, the conveying of solid particles such as ash; Ball compensator then can not directly be installed, and must use in pairs, has the big defective of floor space; And existing bushing type is to utilize asbestos rope to add graphite to compress with bolted bonnet (BB), this seal form is not have elasticity in actual use, in case occur leakage phenomenon can occurring after pipe vibration, the long-time use, reduced the working life of compensator, increased the maintenance cost of pipeline.
The model utility content:
The purpose of this utility model just provides a kind of pipeline compensator of new structure, adopt double seals, guarantee the reliability of sealability, eliminated because of pipe vibration and produced the seepage phenomenon, improve the working life of compensator, have installation, maintenance, change characteristics such as convenient.
The purpose of this utility model is achieved in that a kind of Rockwell pipeline compensator is made up of a pair of gland flange, seal ring, outer ring, pull bar and adjusting nut, about described outer ring is sleeved on two pipelines, it is characterized in that: described a pair of gland flange is fixed on the both sides of described outer ring by described equally distributed some pull bars and adjusting nut, is provided with described seal ring between described outer ring and gland flange.
Several caging bolts have evenly distributed on two groups of circumferences about described outer ring.
The utility model compared with prior art has following advantage:
1. owing to adopt the sealing of Double End self tightening elastic washer, sealability is good, reliable, eliminated original rubber seal and after fastening, killed, improved 3-4 working life doubly, had installation, maintenance, change characteristics such as convenient because of pipe vibration produces the seepage phenomenon.
2. because several caging bolts that on two groups of circumferences about described outer ring, evenly distributed, guaranteed to want the reliability of connecting tube, prevented that compensator from coming off from pipeline 7.
Description of drawings:
Fig. 1 is structural representation 1. gland flange 2. seal rings 3. pull bars 4. outer rings 5. caging bolts, 6. adjusting nuts, 7. pipelines of Rockwell pipeline compensator described in the utility model
Embodiment:
As can be seen from Figure 1, a kind of Rockwell pipeline compensator is made up of a pair of gland flange 1, seal ring 2, outer ring 4, pull bar 3 and adjusting nut 6, about outer ring 3 is sleeved on two pipelines 7, a pair of gland flange 1 is fixed on the both sides of outer ring 4 by equally distributed pull bar 3 and adjusting nut 6, is provided with seal ring 2 between outer ring 4 and gland flange 1.Several caging bolts 5 that evenly distributed on about the 4 two groups of circumferences in outer ring prevent that by caging bolt 5 compensator from coming off from pipeline 7.
This pipeline compensator can be used for the various conveyings that contain solid particles such as powder, ash.
Claims (2)
1. a Rockwell pipeline compensator is made up of a pair of gland flange (1), seal ring (2), outer ring (4), pull bar (3) and adjusting nut (6), about described outer ring (4) is sleeved on two pipelines (7), it is characterized in that: described a pair of gland flange (1) is fixed on the both sides of described outer ring (4) by equally distributed some pull bars (3) and adjusting nut (6), is provided with described seal ring (2) between described outer ring (4) and gland flange (1).
2. a kind of Rockwell pipeline compensator according to claim 1 is characterized in that: several caging bolts (5) have evenly distributed on two groups of circumferences about described outer ring (4).
