Abstract

The invention discloses a pipeline leakage stopping device which comprises a magnet and a sealing gasket below the magnet, wherein two magnets are respectively provided with a piece of soft iron, and the pipeline leakage stopping device also comprises a pin at the upper part of the soft iron and a screw rod connected with the pin. And the screw cap, the ingot head, the cross bolt hole and the cross bolt on the screw rod. In addition, the magnet is externally provided with a shell, and the screw rod penetrates through a central hole of the shell, so that the shell covers the magnet and the soft iron and the pin on two sides of the magnet. The invention adopts magnetic attraction to leak the leakage through the process, has high speed, convenient disassembly and assembly, simple operation, safety and reliability, and can be operated by one person.

Description

Pipeline plugging device

Technical Field

The invention relates to a mechanical device, in particular to a pipeline breakage and leakage stopping device for a naval vessel.

Background

The pipelines on ships are various in types and mainly comprise fresh water pipes, seawater pipes, air pressure pipes, steam pipes and fuel oil pipes.

Due to the special task of the naval vessel, the pipeline is often hit by shells of enemies during battle to damage and leak water, or the pipeline is rotted to generate cracks, which brings serious threat to the safety and the fighting capacity of the naval vessel, and the rapid and firm pipeline leakage stoppage becomes a key problem. Therefore, a plurality of pipeline plugging devices are invented, but the pipeline plugging devices are complex to operate, slow in plugging speed and serious in leakage. Is not suitable for being used on naval vessels. The invention relates to a way for plugging a pipeline by using a magnet on a pipeline plugging device, which effectively solves the difficulties. The pipeline plugging device is not seen in naval vessels at home and abroad so far, and patent documents are not recorded.

Disclosure of Invention

The invention aims to provide a pipeline leakage stopper used on ships and civil ships, which adopts magnetic attraction to stop leakage, has good leakage stopping effect and high speed, is convenient to disassemble and assemble, is simple to operate, is safe and reliable, and can be operated by one person.

In order to achieve the purpose, the invention adopts the technical scheme that: a pipeline plugging device is characterized in that: the magnetic iron comprises a magnet, a sealing pad is arranged below the magnet, soft iron is arranged on each of two sides of the magnet, a pin is arranged on the upper portion of the soft iron, a screw rod is connected with the pin, a nut is arranged on the screw rod, a shoe-shaped gold ingot head is arranged on the nut, a transverse bolt hole is formed in the transverse bolt, and the transverse bolt is arranged on the nut. It is also characterized in that: the magnet is externally provided with a shell, and the screw rod penetrates through a central hole of the shell, so that the shell covers the magnet, soft iron on two sides of the magnet and a pin on the screw rod.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

In the figure: 1-magnet, 2-soft iron 3-shell, 4-pin, 5-screw, 6-nut, 7-ingot head, 8-sealing pad, 9-cross bolt, 10-cross bolt hole, and 11-shell arc ring.

Detailed description of the preferred embodiments

The embodiments of the present invention will be further described with reference to fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, and fig. 6. The pipeline plugging device shown in the attached drawings is characterized in that: there is sealed 8 below magnet 1, magnet 1's two respectively are equipped with a soft iron 2, there is screw rod 5 on soft iron 2 upper portion, screw rod 5 is connected with two soft irons through pin 4, the cap 6 has been tied on screw rod 5, ingot head 7, there is a cross bolt hole 10 on the screw rod 5, cross bolt 9 has been inserted in the cross bolt hole 10, screw rod 5 passes from the central hole of shell 3, make shell 3 cover magnet 1 and two then soft irons 2 and pin 4, there is arc type circle 11 shell 3 bottom.

When plugging, the arc ring of the pipeline plugging device is tightly attached to the pipeline, the sealing gasket 8 is pressed above the damaged opening, the cross latch 9 inserted in the cross latch hole 10 is pulled out, and the sealing gasket 8 is firmly pressed on the damaged opening of the pipeline under the action of the attraction force of the magnet 1 to complete the plugging.

When the pipeline plugging device is disassembled, the nut 6 is only needed to be screwed, the magnet 1 inside the shell and the soft iron 2 of the magnet 1 are enabled to move upwards, the magnetic attraction force of the magnet 1 and the soft iron 2 of the magnet 1 is reduced along with the ascending, and the pipeline plugging device is taken down.
