Description

Technical Field

[0001] The utility model relates to the technical field of packing, in particular to a packing repressor. Background Art

[0002] The packing is also called sealing packing, usually woven by relatively soft linear materials, and filled in the sealing cavity through a strip with a square cross-section to achieve sealing. The packing seal was first used to prevent liquid leakage by stuffing fibers such as cotton and linen in the leakage channel, and there are many varieties and specifications.

[0003] During the use of the packing, over time, water leakage and air leakage often occur due to reasons such as long-term wear of the packing and serious scale in the pipeline. Usually, when encountering this situation, only after the system stops running, the old packing needs to be taken out, and at the same time, a new packing needs to be replaced immediately. The new packing also needs to be subjected to a specific bevel cutting treatment to ensure a tight fit, and then reinstalled and tightly compacted. This process is not only complex and time-consuming, but also increases the labor intensity of the operator for replacement and handling, and is prone to pose a safety hazard to production. The direct consequence of the system shutdown is the temporary interruption of the production line, which not only means an increase in costs, but also directly leads to a reduction in product output, having an immediate and significant negative impact on the economic benefits of the enterprise. Content of the Utility Model

[0004] The purpose of the utility model is to provide a packing repressor, which is used to solve the problems that after the current packing is worn, the way of removing the old packing and replacing it with a new one has a large labor intensity for the operator, is prone to cause equipment shutdown, pose a safety hazard, and lead to a reduction in product output.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A packing repressor, including a flange hoop and an inner ring pressing ring arranged on the flange hoop; the flange hoop includes two relatively arranged semi-circular plates, two mounting holes arranged at intervals on the semi-circular plates, and connection mechanisms respectively arranged at the connection parts on both sides of the two semi-circular plates; the inner ring pressing ring includes a semi-cylindrical tube connected to the inner edge on the upper side of the semi-circular plate, and the two semi-cylindrical tubes are relatively arranged.

[0006] Further, the connection mechanism includes fastening nuts respectively connected to the outer sides of the two semi-circular plates and bolts threadedly engaged with the two fastening nuts.

[0007] Further, the surfaces of the semi-circular plate, the semi-cylindrical tube, the fastening nut, and the bolt are all subjected to rust prevention treatment.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] The utility model has the following beneficial effects:

[0010] In case of air leakage or water leakage, install the flange hoop on the shaft at the packing installation position, so that the two semi-ring plates coincide with the original packing gland. Wind the mud-like packing on the shaft (in front of the inner compression ring). The compression bolts of the original gland pass through the four installation holes, and then use the original packing compression bolts to slowly push the flange hoop inward. During this process, the inner compression ring composed of the two semi-cylindrical tubes squeezes the mud-like packing into the gap of the original packing gland, so as to achieve the effect of tight sealing. One person can easily tighten the packing with this packing compressor, and there is no need to remove the old packing and stop the system, which solves the problems of temporary interruption of the production line, increase in cost, and reduction in product output caused by system shutdown, eliminates potential safety hazards in production, and reduces the labor intensity of operators.

[0014] Please refer to Figure 1-2 , the packing compressor includes a flange hoop and an inner compression ring arranged on the flange hoop; the flange hoop includes two relatively arranged semi-ring plates 1, two installation holes 2 arranged at intervals on the semi-ring plate 1, and connecting mechanisms respectively arranged at the connection positions on both sides of the two semi-ring plates 1; the inner compression ring includes semi-cylindrical tubes 3 welded on the inner edges of the upper sides of the semi-ring plates 1, and the two semi-cylindrical tubes 3 are relatively arranged; the flange hoop uses a DN50 flange and is symmetrically cut; in case of air leakage or water leakage, install the flange hoop on the shaft at the packing installation position. Specifically, the two semi-ring plates 1 are clamped to the outside of the shaft, and then the two semi-ring plates 1 are connected through the two connecting mechanisms, so that the two semi-ring plates 1 coincide with the original packing gland. Wind the mud-like packing on the shaft (in front of the inner compression ring). The compression bolts of the original gland pass through the four installation holes 2, and then use the original packing compression bolts to slowly push the flange hoop inward. During this process, the inner compression ring composed of the two semi-cylindrical tubes 3 squeezes the mud-like packing into the gap of the original packing gland, so as to achieve the effect of tight sealing. One person can easily tighten the packing with this packing compressor, and there is no need to remove the old packing and stop the system, which solves the problems of temporary interruption of the production line, increase in cost, and reduction in product output caused by system shutdown, eliminates potential safety hazards in production, and reduces the labor intensity of operators.

[0015] The connecting mechanism includes fastening nuts 4 respectively connected to the outer sides of the two semi-circular plates 1 and bolts 5 threadedly engaged with the two fastening nuts 4. After the two semi-circular plates 1 are clamped onto the shaft at the packing installation location, the bolts 5 are tightened within the two adjacent fastening nuts 4 to complete the installation of the two semi-circular plates 1 on the shaft at the packing installation location, and it is convenient for disassembly, assembly, and later inspection and replacement.

[0016] The surfaces of the semi-circular plate 1, the semi-circular cylinder 3, the fastening nut 4, and the bolt 5 are all subjected to anti-rust treatment, which improves the service life of this packing replacer.

[0017] Working principle: When there is air leakage or water leakage, the flange clamp is installed on the shaft at the packing installation location. Specifically, the two semi-circular plates 1 are clamped onto the outer side of the shaft. Then, by tightening the bolts 5 within the two adjacent fastening nuts 4, the two semi-circular plates 1 are connected, so that the two semi-circular plates 1 coincide with the original packing pressing plate. The mud-shaped packing is wound on the shaft (in front of the inner pressing ring). The pressing bolts of the original pressing plate pass through the four mounting holes 2, and then the flange clamp is slowly pushed inward by using the original packing pressing bolts. During this process, the inner pressing ring composed of the two semi-circular cylinders 3 squeezes the mud-shaped packing into the gap of the original packing pressing plate, thereby achieving the effect of tight sealing. This packing replacer allows one person to easily tighten the packing, and there is no need to remove the old packing and stop the system, solving the problems of the temporary interruption of the production line, the increase in cost, and the reduction in product output caused by system shutdown, eliminating potential safety hazards in production and reducing the labor intensity of the operators.

[0018] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
