Description

Pipe fitting jointing equipment for hydraulic engineering

Technical Field

The utility model relates to the technical field of pipe fitting connection, in particular to pipe fitting connection equipment for hydraulic engineering.

Background

Hydraulic engineering is an engineering built for controlling and allocating surface water and underground water in nature to achieve the purposes of removing harmful substances and benefiting. Also known as water engineering. Water is a valuable resource essential for human production and life, but its naturally occurring state does not completely meet the needs of human beings. Only when hydraulic engineering is built, water flow can be controlled, flood disasters are prevented, and water quantity is adjusted and distributed to meet the requirements of people on water resources in life and production. Hydraulic engineering needs to build various types of hydraulic buildings such as dams, dikes, spillways, water gates, water inlets, channels, transition troughs, rafts, fishways and the like so as to achieve the aims.

Piping is also important in hydraulic engineering where hydraulic pipes must be used for drainage. The water delivery pipe canal refers to a pipeline or a pipe canal from a water source intake to a water plant and from the water plant to a water supply pipe network, plays a role in delivering water as far as possible and does not distribute water along the line. The water delivery pipeline should be shortened as much as possible, farmland occupation is reduced, pipe canal construction and operation maintenance are facilitated, water supply safety is guaranteed, and double-line water supply is adopted for the water delivery pipeline. The water delivery modes of the water delivery pipe duct can be divided into two types: the first type is that a water source is lower than a water supply area, for example, when river water is taken, a pump station is needed to pressurize and convey the water, and a pump station is sometimes needed to be arranged in the water conveying process according to the conditions of terrain height difference, pipeline length, water pipe pressure-bearing capacity and the like; the second type is that the water source is located higher than the water supply area, for example, when the water in the storage reservoir is taken, it is possible to use gravity pipe to deliver water. The water delivery pipe channel can be of a gravity type or a pressure type according to the terrain height difference change and the terrain change of a water source and a water supply area. When water is transported for a long distance, the terrain is often prone, and more pressure types are adopted. The line of the gravity pipe canal is simple, can be laid below a hydraulic slope line and supplies water according to the shortest distance as possible.

In hydraulic engineering's pipeline engineering actual construction, need plan in advance to the pipeline in the face of complicated topography, in the in-process that runs into the pipeline and not communicate, need to connect through pipe connection equipment to the pipeline that does not communicate, traditional pipe connection equipment can lead to the junction to take place to become flexible to too big water pressure in long-time use, not hard up pipe connection department can cause the leakage, the life of giving people brings inconveniently, cause economic loss, during large-scale pipe connection, there is inconvenience in the butt joint between the pipeline, need to drop into mechanical equipment and manpower resources and carry out the position butt joint to the pipeline, need remove the flange of pipeline and pipeline connection's flange to unified axis on, just can connect, the pipe connection is wasted time and energy.
