Abstract
The utility model discloses a rotary compensator, comprising a rotary connecting pipe, a stuffing gland, a stuffing box, steel balls, an extension connecting pipe, and a disk spring, wherein the rotary connecting pipe is coaxial with the extension connecting pipe, two rolling bearing grooves are arranged between the rotary connecting pipe and the stuffing box and between the rotary connecting pipe and the stuffing gland, the steel balls are arranged in the rolling bearing grooves so as to form the double-support rolling bearing structure; and the disk spring for compensating the stuffing wear consumption is arranged on the stuffing gland. The rotary compensator of the utility model has reliable sealing performance, long service life, large compensation range, and low investment cost, and can be mounted conveniently and is free of maintenance.
Description
Technical field
The utility model relates to compensator, particularly a kind of rotary compensator.
Background technique
Along with development and national economy, thermoelectric industry has obtained growth at full speed, use in the laying of long-distance transmission pipeline at industrial steam, resident's central heat supplying, to solving the pipeline used compensator that expands with heat and contract with cold brand-new requirement has been proposed, but existing corrugated expansion joint, sleeve expansion joint and spherical compensator can not satisfy these requirements, and promptly existing compensator exists that sealability is bad, installation is inconvenient and defective such as troublesome maintenance.
The model utility content
The technical problems to be solved in the utility model is in order to overcome the defective of prior art, a kind of rotary compensator to be provided, the reliable and installation convenience of its sealing.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of rotary compensator, it is characterized in that, it comprises rotation adapter, Gland, Stuffing box, steel ball, extension adapter, belleville spring, rotation is taken over and is taken over coaxial with extension, the rotation adapter is respectively equipped with the rolling bearing groove between Stuffing box, Gland, steel ball is located at and is formed the dual-gripper rolling bearing structure in the rolling bearing groove; The belleville spring of compensation filler attrition is installed on the Gland.
Preferably, described rotary compensator also comprises filler, and filler is positioned at Stuffing box.
Positive progressive effect of the present utility model is: advantage such as the utlity model has that sealing is reliable, long service life, compensation rate are big, less investment, installation are convenient, non-maintaining.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural representation.
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
Embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, rotary compensator of the present utility model comprises rotation adapter 1, Gland 2, Stuffing box 3, steel ball 5, extends adapter 6, belleville spring 7, rotation adapter 1 is coaxial with extension adapter 6, rotary compensator also comprises filler 4, filler 4 is a flexible graphite packing, and filler 4 is positioned at Stuffing box 3.
Rotation is taken over 1 and be respectively equipped with the rolling bearing groove between Stuffing box 2, Gland 3, steel ball 5 is located in the rolling bearing groove, steel ball 5 and rotation are taken over 1 and are cooperated and form the dual-gripper rolling bearing structure, and this dual-gripper rolling bearing structure supports rotation and takes over 1 and the axial float of restriction rotation adapter 1.Belleville spring 7 is installed on the hold-down bolt of Gland 2, because bolt looseness or filler attrition make filler be in impaction state all the time, avoids filler to reveal, reach non-maintaining effect with compensation.
In the said structure, rotation is taken over 1 right-hand member and ball is set and rolls ring with extension adapter 6 places of matching, ball and roll ring and make rotation take over 1 with to extend adapter 6 coaxial and balance the pipeline axial thrust that causes because of interior pressure, in addition, Gland 2 is taken over 1 place of matching with rotation and ball also is set and rolls ring, rotation is taken over 1 form coaxial dual-gripper, so coaxality height, make when rotating operation is made in rotation adapter 1, accept suffered radial force, guarantee that the wearing and tearing that filler 4 produces are uniform coaxial wearing and tearing, help structure compensation or adjustment sealing automatically, also help rotation and take over 1 extension adapter 6 relatively, the motion of Stuffing box 3 and Gland 2, and the frictional force that when rotation produces is less relatively.
Belleville spring prevents the loosening structure of revealing of filler as shown in Figure 2, slidably Gland 2 and the relative static filler 4 and the axial compression of Stuffing box 3 make up pre-stressed joint by through hole uniform on the Gland 2 sealing seat ends and nut bolt belleville spring and realize.Rotation adapter 1 causes the normal wear of filler 4 naturally when rotating, owing under the promotion of the active force that compresses dish-shaped spring force, compensate its wear extent automatically, keep the sealing of 4 pairs of components that match of filler.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, protection domain of the present utility model is limited by appended claims.
Claims (2)
1. rotary compensator, it is characterized in that, it comprises rotation adapter, Gland, Stuffing box, steel ball, extension adapter, belleville spring, rotation is taken over and is taken over coaxial with extension, the rotation adapter is respectively equipped with the rolling bearing groove between Stuffing box, Gland, steel ball is located at and is formed the dual-gripper rolling bearing structure in the rolling bearing groove; The belleville spring of compensation filler attrition is installed on the Gland.
2. rotary compensator as claimed in claim 1 is characterized in that described rotary compensator also comprises filler, and filler is positioned at Stuffing box.
