Abstract
The utility model relates to a single-sealed maintenance-free compensator, which comprises a casing pipe I and a casing pipe II which are mutually connected. The end parts of the casing pipe I and the casing pipe II are respectively provided with end rings I and II, and outer shells are sheathed at the outer surfaces of the end rings I and II. At least two grooves are respectively arranged in the surfaces of the end rings I and II, and O-shaped seal rings with unequal diameters are respectively arranged in the grooves. Two ends of the outer shells are respectively provided with fixing rings, and the fixing rings are fixedly connected with the outer shells through bolts. Compared with the prior art, the outer shells, the end rings, the fixing rings and the at least two O-shaped seal rings with unequal diameters form the pipeline compensator, the deflection angle displacement and the axial displacement of the compensator are larger, and the compensator can effectively compensate and absorb the displacement generated by pipeline equipment during operation. The single-sealed maintenance-free compensator has a better sealing effect and basically does not need maintenance in the service life of pipelines, the manufacture and the installation are convenient, and the service life is long.
Description
Technical field
The utility model relates to the compensation of pipeline device, can realize bending motion mutually and the single closed maintenance free compensator that rotates mutually between especially a kind of pipeline.
Background technique
At present, industries such as electric power, building materials, heating power generally all need be installed and used the three-dimensional tube compensator in pipeline, the three-dimensional tube compensator is made up of two ball-type devices and a sleeve means usually, the ball-type device can be done the radial angle displacement, sleeve means can be done axial straight-line displacement, the deflection angle of three-dimensional tube compensator is big, axial displacement is big, produce in the time of effectively compensating and absorb the operation of equipment such as boiler than big displacement quantity.
The three-dimensional tube compensator that install in existing power plant and cement plant is generally all at cigarette wind or pulverized coal channel design, the structure relative complex of three-dimensional tube compensator, make and install all inconvenient, the Sealing of three-dimensional tube compensator uses leakage phenomenon just easily took place in three to five years, thereby must change compensator, cause the working life of compensator short, maintenance and the workload of changing are big, and cost is higher.
The model utility content
At the deficiency of above existing pipeline compensator, the purpose of this utility model provides a kind of good sealing effect, basic Maintenance free in the using process, and manufacturing, single closed maintenance free compensator easy for installation.
The purpose of this utility model is achieved by the following technical solution:
Single closed maintenance free compensator, comprise sleeve pipe I and sleeve pipe II separate and that diameter is identical, the outer surface of sleeve pipe I end is provided with the end ring I, the outer surface of sleeve pipe II end is provided with the end ring II, sleeve pipe I and sleeve pipe II are passed through frame, end ring I and end ring II interconnect, be provided with the gap between described sleeve pipe I and the sleeve pipe II, make sleeve pipe I and sleeve pipe II can bend motion or rotation mutually mutually, described frame is set in the outer surface of end ring I and end ring II, the surface of end ring I and end ring II is respectively equipped with at least two grooves, be respectively equipped with the O RunddichtringO that diameter does not wait in the groove, the two ends of described frame are respectively equipped with retaining ring, and retaining ring is connected with frame by bolt and fixes.
As optimal technical scheme of the present utility model, be respectively equipped with O RunddichtringO I and O RunddichtringO II between described end ring I, end ring II and the frame, the diameter of described O RunddichtringO I is greater than the diameter of O RunddichtringO II.
As optimal technical scheme of the present utility model, described end ring I and sleeve pipe I are welded to connect, and end ring II and sleeve pipe II are welded to connect.
As optimal technical scheme of the present utility model, the gap between described sleeve pipe I and the sleeve pipe II is less than 1/3rd of sleeve pipe I diameter.
As optimal technical scheme of the present utility model, be respectively equipped with the transportation lock bolt between the retaining ring at described frame two ends and end ring I and the end ring II.
The beneficial effects of the utility model are: with respect to prior art, the utility model adopts frame, end ring, retaining ring and at least two O RunddichtringO formation pipeline compensators that diameter does not wait, deflection angle displacement amount and the axial displacement of compensator are bigger, can effectively compensate the displacement that produces when moving with extraction duct equipment.Good sealing effect of the present utility model, reliable high, basic Maintenance free in the working life of pipeline, manufacturing, easy for installation, long service life.
