The device comprises an upper mounting seat, a lower mounting seat and a rubber compensation cylinder positioned between the upper mounting seat and the lower mounting seat, wherein two ends of the rubber compensation cylinder are respectively fixed on the upper mounting seat and the lower mounting seat, a spiral spring column is arranged on the outer wall surface of the rubber compensation cylinder, and two ends of the spiral spring column are respectively connected with the upper mounting seat and the lower mounting seat; a plurality of adjustable pull rods are arranged between the upper mounting seat and the lower mounting seat. The utility model has the advantages of long service life and the like.
Description
Technical Field
The utility model belongs to the technical field of pipeline connectors, and relates to a nonmetal compensator.
Background
The nonmetal compensator is also an expansion joint and is used for compensating the connection errors of the pipelines in the axial direction, the transverse direction and the angular direction, eliminating the expansion caused by heat and contraction caused by cold, improving the installation portability, protecting the pipe fittings and the like, and has the characteristics of no thrust, simplifying the design of a support, resisting corrosion, silencing and damping.
The existing nonmetallic compensator mainly comprises two mounting seats and a corrugated pipe positioned between the two mounting seats, an axial limiting part is arranged between the two mounting seats, the flexible deformation of the corrugated pipe is utilized to realize the adjustment of compensation gaps, however, fluid (such as air flow and liquid flow) in a pipeline connected with the compensator is easy to accumulate at the corrugated pipe, a plurality of annular grooves and annular protrusions formed on the inner wall of the corrugated pipe form obstruction to the movement of the fluid, and the abrasion to the rubber corrugated pipe can be greatly increased.
Disclosure of Invention
The present utility model is directed to providing a non-metal compensator, which aims to solve the above problems in the prior art, and how to prolong the service life of the compensator.
The aim of the utility model can be achieved by the following technical scheme: the nonmetal compensator is characterized by comprising an upper mounting seat, a lower mounting seat and a rubber compensation cylinder positioned between the upper mounting seat and the lower mounting seat, wherein two ends of the rubber compensation cylinder are respectively fixed on the upper mounting seat and the lower mounting seat, a spiral spring column is arranged on the outer wall surface of the rubber compensation cylinder, and two ends of the spiral spring column are respectively connected with the upper mounting seat and the lower mounting seat; a plurality of adjustable pull rods are arranged between the upper mounting seat and the lower mounting seat.
Under the action of the extrusion force between the upper mounting seat and the lower mounting seat, the rubber compensation cylinder between the upper mounting seat and the lower mounting seat is compressed, and a certain pressure is formed on the inner wall of the rubber compensation cylinder through the air flow or the liquid flow in the rubber compensation cylinder, so that the rubber compensation cylinder is tightly attached to the spiral spring column outside the rubber compensation cylinder, further, the deformation of the rubber compensation cylinder can form a spiral ring groove, the ring groove is matched with the spiral path of the spiral spring column, compared with a traditional corrugated pipe, the spiral ring groove in the scheme has a guiding effect on fluid, is not easy to accumulate, reduces the friction force of the fluid on the rubber compensation cylinder, simultaneously, when the extrusion force of the fluid on the rubber compensation cylinder disappears, the rubber compensation cylinder can be recovered, the inner side of the rubber compensation cylinder is prevented from being flattened, the positions of the spiral ring groove are also different and the depths are also different under different fluid pressures, so that the local abrasion of rubber materials is not easy to be caused, the abrasion of each part is relatively uniform, and the service life is greatly prolonged.

FIG. 1 is a schematic diagram of the structure of the compensator without the fluid in the rubber compensator cylinder forming an expansion pressure for it.
FIG. 2 is a schematic diagram of the structure of the compensator when there is fluid in the rubber compensator cylinder to create an expansion pressure thereto.
In the figure, 1, an upper mounting seat; 2. a lower mounting seat; 3. a rubber compensation cylinder; 4. a coil spring post; 5. an adjustable tie rod.
Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
The nonmetallic compensator shown in fig. 1 and 2 comprises an upper mounting seat 1, a lower mounting seat 2 and a rubber compensation cylinder 3 positioned between the upper mounting seat 1 and the lower mounting seat 2, wherein two ends of the rubber compensation cylinder 3 are respectively fixed on the upper mounting seat 1 and the lower mounting seat 2, a spiral spring column 4 is arranged on the outer wall surface of the rubber compensation cylinder 3, and two ends of the spiral spring column 4 are respectively connected with the upper mounting seat 1 and the lower mounting seat 2; a plurality of adjustable pull rods 5 are arranged between the upper mounting seat 1 and the lower mounting seat 2.
Under the action of the extrusion force between the upper mounting seat 1 and the lower mounting seat 2, the rubber compensation cylinder 3 between the upper mounting seat 1 and the lower mounting seat is compressed, and a certain pressure is formed on the inner wall of the rubber compensation cylinder 3 through the air flow or the liquid flow in the rubber compensation cylinder 3, so that the rubber compensation cylinder 3 is tightly attached to the spiral spring column 4 positioned outside the rubber compensation cylinder 3, further, the deformation of the rubber compensation cylinder 3 can enable the rubber compensation cylinder 3 to form a spiral ring groove, the ring groove is matched with the spiral path of the spiral spring column 4, compared with a traditional corrugated pipe, the spiral ring groove in the scheme has a guiding effect on the fluid, is not easy to accumulate, reduces the friction force of the fluid on the rubber compensation cylinder 3, simultaneously, when the extrusion force of the fluid on the rubber compensation cylinder 3 is eliminated, the rubber compensation cylinder 3 is recovered, the inner side is prevented from being flattened, the positions of the spiral ring grooves are different and the depths are different under different fluid pressures, so that the local abrasion of rubber materials is not easy to be caused, the abrasion of each part is relatively uniform, and the service life is greatly prolonged.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
