Abstract
Description
Technical Field
[0001] The utility model relates to the field of clamps for compensators, and particularly to a clamp for a compensator. Background Art
[0002] In the operation of municipal heating pipe networks, compensators often leak. Since compensators are generally installed on the main pipe network, the time for shutdown and replacement is long and the social impact is large. Therefore, it is necessary to invent a clamp for a compensator to temporarily block the leakage of the compensator and at the same time ensure the normal operation of the compensator.
[0003] Clamps are generally used for water supply pipes. The tightening of the inner skin pad of the clamp and the bolts on the clamp closes the water leakage point under pressure inside the pipe. Based on this characteristic of the clamp, we consider extending the clamp technology to the leakage of compensators in heating pipe networks. Traditional clamps are integrally formed of cast iron or stainless steel. Since the compensator has a larger outer diameter than the pipe, a step is required. Therefore, the clamp for the compensator needs to be formed into a whole by welding a ring plate and a hoop cylinder. However, integral forming will affect the stretching function of the compensator, thereby affecting the use of the compensator. Summary of the Utility Model
[0004] An object of the utility model is to provide a clamp for a compensator that solves at least one aspect of the above technical problems.
[0005] A further object of the utility model is to avoid the inability of the compensator to expand and contract normally after installation.
[0006] Another further object of the utility model is to improve the use effect so that the clamp still has the function of expansion and contraction after installation.
[0007] In particular, the utility model provides a clamp for a compensator, including a hoop cylinder;
[0008] A glue injection ring plate and a welding ring plate, the glue injection ring plate is arranged at one end opening of the hoop cylinder, and the welding opening is arranged at the other end opening of the hoop cylinder; a glue injection hole penetrating through the glue injection ring plate is arranged on the glue injection ring plate;
[0009] A drain valve, the drain valve is arranged at the lower part of the hoop cylinder.
[0010] Further, the glue injection ring plate includes an upper plate ring plate and a lower plate ring plate of the same size, and both the upper plate ring plate and the lower plate ring plate are welded to the hoop cylinder.
[0011] Further, the welding ring plate includes two identical ring plates, both of which are fixedly connected to the hoop cylinder by welding.
[0012] Further, the hoop cylinder includes an upper hoop cylinder and a lower hoop cylinder. The upper hoop cylinder and the lower hoop cylinder are buckled on the compensator and fixedly connected by bolts passing through bolt holes. And a drain valve is connected to the lower hoop cylinder.
[0013] Further, the inner circle of the ring plate is 1 mm larger than the outer diameter of the working pipe, and the outer circle is 2 - 3 mm larger than the inner and outer diameters of the hoop cylinder.
[0014] Further, a reinforcing angle is provided on one side of the welded ring plate.
[0015] The technical effects and advantages of the present utility model:
[0016] After the compensator leaks, the present utility model can not only achieve the purpose of rush repair without stopping heating, but also greatly shorten the rush repair time. At the same time, in order to enable the compensator to still have the stretching function, one side of the ring plate is welded and connected to the working pipeline, and a groove is opened on the other side of the ring plate. Injection valves are installed by drilling holes on the outer side of the ring plate.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] Figure 1 It is a schematic structural diagram of the present invention. Figure 2 It is a schematic top view structural diagram of the present invention. Figure 3 For the present invention Figure 2 It is a schematic cross-sectional structural diagram in the A-A direction in the present invention.
[0024] The solution of this embodiment provides a compensator clamp, which includes a hoop barrel, a drain valve 7, a glue injection ring plate 3 and a welding ring plate 4. The glue injection ring plate 3 is welded at one open end of the hoop barrel, and the welding opening is welded at the other open end of the hoop barrel; a glue injection hole 303 penetrating through the glue injection ring plate 3 is arranged on the glue injection ring plate 3, and the glue injection holes 303 are equidistantly arranged along the arc surface of the glue injection ring plate 3. By inserting a glue injection valve 8 into the glue injection hole 303, the inner side of the glue injection ring plate 3 is sealed with the steel pipe 2 with glue; the drain valve 7 is arranged at the lower part of the hoop barrel for draining water.
[0025] It should be further noted that the glue injection ring plate 3 includes an upper plate ring 301 and a lower plate ring 302 of the same size. Both the upper plate ring 301 and the lower plate ring 302 are welded to the hoop barrel to form the entire ring plate. It should be noted that the connection part of the upper and lower half ring plates is completely welded.
[0026] It should be further noted that the welding ring plate 4 includes two identical ring plates, both of which are fixedly connected to the hoop barrel by welding. The fixing method is the same as that of the glue injection ring plate 3, but the welding ring plate 4 is directly welded to the steel pipe 2. A reinforcing angle 6 is arranged on one side of the welding ring plate 4, and the reinforcing angle 6 is used to stabilize the entire hoop barrel.
[0027] It should be further noted that the hoop barrel includes an upper hoop barrel 501 and a lower hoop barrel 502. The upper hoop barrel 501 and the lower hoop barrel 502 are buckled on the compensator 1 to form a sealed cavity, and are fixedly connected by bolts passing through bolt holes 10, and then sealed by welding the gap or pressing with a gasket. And the lower hoop barrel 502 is connected with a drain valve 7.
[0028] It should be further noted that the inner circle of the ring plate is 1 mm larger than the outer diameter of the working pipe, and the outer circle is 2 - 3 mm larger than the inner and outer diameters of the hoop barrel; after the ring plate is fabricated, it is welded to both sides of the hoop barrel. The welding is carried out in a two-way manner inside and outside. After the ring plates on both sides are welded to the hoop barrel, a drain valve 7 is installed at the lowest point of the hoop. After installation, the hoop is cut in half along the center line of the hoop, and connecting bolts are symmetrically welded on both sides of each half of the hoop for use during subsequent alignment. In this way, one compensator 1 hoop is fabricated. During installation, the two halves of the hoop are installed on both sides of the working pipe and the compensator 1. When installing, it should be noted that the leakage valve must be placed at the topmost point to ensure that the leaked water can be discharged smoothly. Then, the side of the fixed ring plate is welded to the working pipe, and the welds on the cut hoop barrel are fully welded. A 20 mm * 20 mm packing is installed in the groove of the movable ring plate part. Before injecting glue, the drain valve 7 is closed, and then glue is injected into the groove hole by hole until there is no more leakage. After the glue injection is completed, the glue injection valve 8 needs to be closed.
[0029] Working principle of the utility model:
[0030] During use, after leakage of the compensator 1, not only can the purpose of repairing without stopping heating be achieved, but also the repair time is greatly shortened. At the same time, in order to enable the compensator 1 to still have the stretching function, one side of the ring plate is welded and connected to the working pipe, and a groove is opened on the other side of the ring plate. A glue injection valve 8 is installed by drilling holes on the outer side of the ring plate. By injecting glue into the ring plate, a flexible seal is formed between the ring plate and the working pipe, so as to achieve the purpose of stopping water while enabling the compensator 1 to work normally.
[0031] Finally, it should be noted that the above are only the preferred embodiments of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent substitution on some of the technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
