Abstract
The utility model discloses an online filling type spherical compensator which comprises a variable-diameter pipe, a shell, a filling hole, filler, sealing rings, steel balls and a spherical pipe. The shell is a circular shell body; the spherical pipe is arranged in an inner cavity of the shell; the filler is filled between the inner cavity of the shell and a sphere of the spherical pipe; and the sealing rings are fixedly connected with the two ends of the inner wall of the shell for sealing and blocking the filler so as to form a spherical sealing structure. 4-16 radial holes are uniformly distributed on the outer wall of the shell and are respectively and fixedly connected with the filling hole. The inner wall of each sealing ring is a circular arc surface matched with the spherical pipe; a ring groove is arranged in the middle of the circular arc surface; and the steel balls are uniformly distributed in the ring groove and are matched with the outer wall of the spherical pipe to form a rolling and supporting structure. The spherical pipe can more flexibly and lightly rotate or swing by means of the rolling and supporting structure, so that the angular compensation is quicker. With the adoption of the online filling type spherical compensator, after the filler is abraded, a filling gun can be adopted for online compensation through the filling hole, shutdown and structural disassembly are not needed, and the leakage can be immediately eliminated, so that the safety of the production site is improved.
Description
Technical field
The utility model relates to a kind of pipe safety device, and specifically, the utility model relates to a kind of online filling type ball compensator.
Background technique
When industry pipe network and municipal heating systems operation, also there is angular displacement in some nodes except that telescopic displacement is arranged.Current, ball compensator is an optimum pipeline safety installations of eliminating angular displacement, in engineering, is generally used.But; The ball compensator of existing technology still exists structure not enough, and particularly sealing configuration is unreasonable, and the fault point mainly concentrates on the ball face sealing structure in the use; Frequent rotation must make sealing pair produce corresponding wearing and tearing, and excessive wear was lost efficacy ball face sealing structure and caused leakage.The ball compensator of existing technology is daily can realize that sealability improves through further compressing filler, if built-in filler is by excessive abrasion, even adjustment is also invalid, has only to shut down and unloads sealing configuration and replace filler again and could recover sealability.But most of industrial pipe networks can not stop at any time, cause spherical compensator to be safeguarded to can not get timely reparation thus, and lasting leakage is unfavorable for production scene safety.
The model utility content
The utility model is primarily aimed at the deficiency of existing technology, proposes a kind of simple in structure, easy to maintenance, online filling type spherical compensator of reliable sealing.
The utility model is realized technical goal through following technical proposals.
Online filling type ball compensator, it comprises reducer pipe, shell, filler, filler, seal mouth ring, steel ball and bulb tube.Said shell is a circular shell, and bulb tube is built in the shell inner cavity, fills in charge between the spheroid of chamber and bulb tube in the enclosure, and seal mouth ring is fixedly connected on outer casing inner wall two ends block filler and constitutes ball face sealing structure.Its improvements are: said housing ring stage casing outer wall is uniformly distributed with 4～16 radial holes and is fixedly connected filler respectively.Said seal mouth ring inwall is the arc surface that matches with bulb tube, is provided with ring groove on this arc surface between two parties, and steel ball is distributed in the ring groove and cooperates formation rolling bearing structure with the bulb tube outer wall.
Used filler is a graphite in the said structure.
The utility model compared with prior art has following good effect:
1, simple in structure, be prone to make;
2, shell heavy caliber end is uncovered structure, the non-structure obstacle, and the angular compensatory amount is greater than ± 5 °;
3, bulb tube is by more flexible, the light swing of rolling bearing, and angular compensatory is quick;
4, can need not shut down and do the structure disintegration respectively from the online injection filler of filler after the filler wearing and tearing, stop a leak in time, production scene safety is strengthened.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
According to accompanying drawing and combine embodiment, the utility model is described further below.
Online filling type ball compensator shown in Figure 1, it comprises reducer pipe 1, shell 2, filler 3, filler 4, seal mouth ring 5, steel ball 6 and bulb tube 7.Said shell 2 is a circular shell, and bulb tube 7 is built in shell 2 inner chambers, plug charge 4 between the spheroid of shell 2 inner chambers and bulb tube 7, and seal mouth ring 5 is fixedly connected on shell 2 inwall two ends block fillers 4 and constitutes ball face sealing structure.Present embodiment is the online filling type spherical compensator of DN250mm; Used filler 4 is a graphite; Shell 2 ring stage casing outer walls are uniformly distributed with 4 radial holes and are fixedly connected filler 3 respectively, and available filling gun need not shut down and do the structure disintegration from filler 3 online being replenished in filler 4 wearing and tearing backs; Accomplish to stop a leak in time, production scene safety is strengthened.Being positioned at the seal mouth ring 5 at shell 2 inwall two ends, is filler 4 blocks, also is the skeleton of rolling bearing.Seal mouth ring 5 inwalls are the arc surface that matches with bulb tube 7 spheries, are provided with ring groove on this arc surface between two parties, and steel ball 6 is distributed in the ring groove and cooperates formation rolling bearing structure with bulb tube 7 outer walls.Bulb tube 7 makes angular compensatory faster by more flexible, the light swing of rolling bearing.
