Description

Technical Field

[0001] The utility model relates to the technical field of pipeline leakage emergency repair, in particular to a heating large-diameter pipeline leakage emergency repair sleeve device. Background Art

[0002] As we all know, with the continuous expansion of the centralized heating area in northern cities, the diameter of the main heating pipelines has also increased. The problem of quickly solving the pressure plugging of large-diameter pipelines has become increasingly prominent, requiring emergency repair units to restore heating within a certain period of time. Traditional pipeline leakage repair devices have the following shortcomings: the existing pipeline repair sections, due to their unreasonable structure, must have specifications corresponding to the specific specifications of the repair pipelines, that is, a pipeline repair section of one specification can only be used for the repair of ruptured pipelines of a corresponding specification. The targetedness is single and its adaptability is insufficient. This is a prominent defect in the race against time for emergency repairs of pipeline ruptures and leaks, which often affects the timely and rapid repair of pipelines;

[0003] Therefore, after searching the prior art, it is found that the patent technology that has been disclosed, such as a convenient and efficient pipeline repair device proposed in the publication number CN113251239A, has a working principle that when using it, it does not need to be selected according to the specific specifications of the pipeline, etc., and can be adapted to the repair of pipelines of different specifications. In particular, the on-site repair operation is very simple, convenient, and fast, and the operability is particularly strong. At the same time, it can apply the corresponding sealing extrusion force according to the fluid medium pressure of different operating conditions in the pipe to obtain a corresponding appropriate and suitable sealing degree, with good sealing performance, good sealing effect, high sealing reliability, and fast, timely, effective and reliable repair of pipelines under fluid medium conditions in various operating environments, and is particularly practical.

[0004] However, in actual use, we found that the simple fixing method of female buckle and male buckle, as well as the traditional use of clamps, steel belts, etc. to deal with large diameter pipeline leakage often have many disadvantages. The existing large diameter pipeline leakage has high water pressure and high water temperature, and the pipeline wound surface is uneven, and the plugging effect is not good, which reduces the efficiency and effect of the pipeline leakage repair device, resulting in poor practicality.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , a heating large-diameter pipeline leakage repair sleeve device, comprising a leaking pipeline 1, and a repair mechanism is arranged at the outer end of the leaking pipeline 1;

[0025] The emergency repair mechanism also includes a lower sleeve 2, an upper sleeve 3, a baffle 4 and a pressure relief ball valve 5. One side of the lower sleeve 2 is respectively connected to the bottom end of the corresponding baffle 4, the upper sleeve 3 and the corresponding baffle 4 are provided with mounting grooves, and multiple groups of baffles 4 are slidably clamped with the corresponding upper sleeve 3 through the mounting grooves. A leakage pipe 1 is provided between the upper sleeve 3 and the lower sleeve 2, the top end of the upper sleeve 3 is connected to the mounting end of the pressure relief ball valve 5, and the bottom end of the lower sleeve 2 is connected to the mounting end of the pressure relief ball valve 5. The upper sleeve 3 and the lower sleeve 2 are provided with lifting mechanisms, and the outer ends of the upper sleeve 3 and the lower sleeve 2 are provided with adjustment mechanisms.

[0026] When the equipment is in use, the repair mechanism, the adjustment mechanism and the lifting mechanism are used. First, the upper sleeve 3 and the lower sleeve 2 are placed near the leaking pipe 1 by using a lifting device such as an excavator. The telescopic rod 10 is adjusted to place the lifting bracket 7 above the leaking pipe 1. After the fixing foot 9 is fixed, the direction of the leaking water flow of the leaking pipe 1 is determined. The pressure relief ball valve 5 of the lower sleeve 2 or the upper sleeve 3 is opened in advance. The sleeve side lifting ear 6 is used to adjust the sleeve angle with the manual hoist 8 so that the direction of the pressure relief ball valve 5 is aligned with the water flow at the leaking point. The directions are consistent, and preliminary welding is performed to fix the lower sleeve 2 on the pipe wall; the bracket 7 and the manual hoist 8 are used to place the upper sleeve 3 in the baffle 4 groove of the lower sleeve 2, and the manual hoists 8 in the four directions of the upper side are used to quickly complete the weld butt joint. After the sleeve position is adjusted as a whole, the sleeve and the pipe wall, and the upper and lower sleeve butt joints are fully welded. After welding is completed, the ball valve is closed and the pressure sealing operation is completed. This pipeline leakage repair sleeve device saves manpower to the greatest extent, quickly connects the welds, and improves the repair efficiency. It solves the problems of high pressure in large-diameter pipelines and slow manual butt welding speed. Sealing the pipeline wall by welding can avoid the risk of secondary leakage to the greatest extent. Compared with emergency repair devices such as clamps and steel belts, the sleeve has a large operating surface and has the advantages of large pressure relief flow. Pressure sealing does not affect pipeline heat transportation and ensures stable heat for heat users. Through a sleeve device that is convenient for emergency repair of large-diameter heating pipelines, welding can be used to completely solve the leakage, which is convenient for quickly completing the sealing operation under different working conditions. Therefore, the use efficiency and effect of the pipeline leakage repair device are enhanced, thereby enhancing practicality.
