Abstract
Description
Technical Field
[0001] The invention relates to a device for processing freezing of water pipes. Background Art
[0002] As the northern part of China, the region is vast and has four distinct seasons. Especially in winter, the temperature is extremely cold. For example, the lowest temperature in Xinjiang and Northeast China reaches -30℃. This has brought serious difficulties to the production of industrial enterprises in the north, especially to the steel enterprises. Almost all the production processes of steel plants of steel enterprises require water. Water is used to cool equipment components, wash products or smoke-containing gases. Steel plants use a large amount of water and the water supply cannot be interrupted. Therefore, antifreeze and heat preservation in winter production have become the top priority of the production organization of steel enterprises. In winter, if there is a shutdown and water shortage, the cooling water stays in the pipeline and cannot be discharged in time. It will be frozen and frozen, causing serious production accidents. However, some hydraulic pipelines have the characteristics of U-shaped bends and climbing. It is not easy to discharge water during shutdown. If the operator is not careful, it will cause frozen pipe accidents. The traditional treatment of frozen pipe accidents mainly uses electric heating and electric welding machine short-circuit methods. Using heating wires consumes high power and has the dangers of electric shock and fire. Electric welding machine short circuit method: disconnect the hand line, wrap one end of the wire around one end of the water pipe, and wrap the other end of the wire with the welding clamp around the other end of the water pipe, adjust the electric welding machine to the rated current value or slightly larger, turn on the welding machine to short circuit intermittently, so that the ice in the water pipe will melt. This method cannot handle longer pipes. At the same time, the processing efficiency is not high, the processing difficulty is relatively large, and it cannot solve the problem of frozen pipes in long and large pipes. Summary of the invention
[0003] The purpose of the present invention is to provide a device for handling frozen water pipes, which can handle the frozen pipe problems of long and large pipes, has a reasonable structure, high handling efficiency, and reduced handling difficulty, thereby reducing the accidental losses caused by such frozen pipes in production.
[0004] The object of the present invention is achieved in this way: a device for handling frozen water pipes, a valve of a steam source pressure device is connected to a flexible pipe through a steam supply pipeline, the flexible pipe and the pipe reduction head of a reduction joint connector are connected after being compressed by a pre-tightening nut hoop, a first and a second pre-tightening nut are installed on the reduction joint connector, the other end of the reduction joint connector is connected to a steel pipe through a welding structure, the other end of the steel pipe is connected to a connecting annular cylinder with an external thread through a welding structure, the connecting annular cylinder is connected to a connecting annular cylinder with an internal thread through one end of the thread, the other end of the connecting annular cylinder with an internal thread is also connected to a connecting annular cylinder with an external thread at one end, and the other end of the connecting annular cylinder with an external thread is welded to a steel pipe.
[0005] In the present invention, the steam supply of the steam source pressure device is controlled by the valve behind it, and the steam with a certain temperature is transported to the connected flexible pipe through the steam supply pipeline. The flexible pipe and the contraction head of the contraction joint pipe fitting are connected after being compressed by the pre-tightening nut hoop. The first pre-tightening nut and the second pre-tightening nut are installed on the contraction joint pipe fitting to make the contraction joint pipe fitting and the flexible pipe tightly connected to prevent collapse and cracking due to the rise and fall of the steam source. The other end of the contraction joint pipe fitting is connected to a steel pipe of suitable size with a steel structure at one end that can enter the inside of the freezing water pipe by welding. The welding method adopts triangular weld circumferential welding.
[0006] The key technologies of the device of the present invention are as follows: when the length of the frozen pipe is long, the aforementioned steel structure can enter the inside of the frozen water pipe, and the steel pipe of appropriate size cannot meet the thawing needs of the long frozen pipe, the present invention adopts the method of welding the front end of the steel pipe to one end without threads, and adopts a circumferential sealing welding connection with a raised weld surface, and the other end has a connecting annular cylinder with external threads. The connecting annular cylinder with external threads is connected to a connecting annular cylinder with a through internal thread through one end of the thread, and the other end of the connecting annular cylinder with the through internal thread is also threadedly connected to a connecting annular cylinder with an external thread at one end, and the other end of the connecting annular cylinder is welded to a steel pipe, and the welding method also adopts a circumferential sealing welding connection with a raised weld surface.
[0007] The present invention has a reasonable structure and solves the problem that frozen pipes of long pipelines and large pipelines cannot be effectively and quickly handled. The present invention can quickly connect steel thawing pipes, and at the same time, the length of the thawing pipes can be conveniently adjusted. The angle of the thawing pipes can be conveniently adjusted through flexible pipe connection, so as to achieve the purpose of rapid thawing and resumption of production.
