Abstract
The utility model relates to a high pressure pipeline, particularly to a conservation-oriented high pressure pipeline. The conservation-oriented high pressure pipeline comprises a bent pipe, a three-way pipe and a straight pipe for connecting the bent pipe and the three-way pipe, wherein, ring flanges are arranged on the three-way pipe and the straight pipe, which are connected via the ring flanges. The high pressure pipeline is characterized in that the straight pipe comprises a connecting pipe and a short thread pipe with ring flanges, the connecting pipe is welded with the short thread pipe, the bent pipe is welded with the connecting pipe as well, and the wall thickness of the bent pipe, the three-way pipe and the short thread pipe is bigger than that of the connecting pipe. The high pressure pipeline has the advantages of large circulation area and small circulation resistance of the pipes, less energy consumption of the equipment for long term operation, reasonable structure and low manufacturing cost, and saves materials.
Description
Technical field
The utility model relates to a kind of high pressure pipe line, especially relates to a kind of economizing type high pressure pipe line.
Background technique
As everyone knows, the high pressure pipe line that is applied to chemical fertilizer, chemical industry in the market is made of the straight tube of bend pipe, threeway and bridge piece and threeway mostly, and threeway and straight tube are provided with flange plate, and straight tube is connected by flange plate with threeway.Because the design of high pressure pipe line specification is with the weak part of the serial pipe fitting of integral body, just Intensity Design is carried out at the screw thread position of screw thread short tube, and makes screw thread short tube, bend pipe, threeway and straight tube by the pipe of this strength specification.Therefore, the high pressure pipe line of this structure exists the phenomenon of bend pipe, threeway and straight tube intensity surplus, has caused unnecessary waste of material.In addition, because the pipeline circulation area is little, the pipeline circulating resistance is big, has caused the increase of equipment long-time running energy consumption.
Summary of the invention
The utility model mainly is the technical problem little at existing in prior technology pipeline strength surplus, waste material, pipeline circulation area, that the pipeline circulating resistance big, equipment long-time running energy consumption is big etc., and a kind of material, the pipeline circulation area is big, the pipeline circulating resistance is little, equipment long-time running energy consumption is less economizing type high pressure pipe line saved is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of economizing type high pressure pipe line, comprise bend pipe, threeway, and the straight tube of bridge piece and threeway, threeway and straight tube are provided with flange plate, straight tube is connected by flange plate with threeway, it is characterized in that described straight tube is made up of the screw thread short tube of taking over and be provided with flange plate, take over and the screw thread short tube between by being welded to connect, by being welded to connect, the wall thickness of described bend pipe, threeway and screw thread short tube is greater than the wall thickness of taking between bend pipe and the adapter.Straight tube is made up of the screw thread short tube of taking over and be provided with flange plate, relative less at the adapter wall thickness that screw thread short tube and bend pipe directly are welded to connect with bend pipe, threeway and screw thread short tube, saved material to a great extent, reduced manufacture cost, improved the pipeline circulation area simultaneously, reduced the pipeline circulating resistance.
As preferably, between described flange plate and the screw thread short tube by being threaded.By flange plate and the screw thread short tube of being threaded, its rational in infrastructure, simple installation.
As preferably, between described flange plate and the threeway by being threaded.By flange plate and the threeway of being threaded, its rational in infrastructure, simple installation.
As preferably, the wall thickness of described bend pipe, threeway and screw thread short tube equates.The bend pipe of unified specification manufacturing, threeway and screw thread short tube have guaranteed the intensity of high pressure pipe line, and easily manufactured, the assembling easy.
As preferably, the ratio of the wall thickness of described adapter and bend pipe or screw thread short tube wall thickness is 1: 1.1～1: 1.3.The adapter that can design different wall according to the high pressure pipe line adjustment of different specification size matches with it, and it is rational in infrastructure, design is ingenious.
As preferably, be connected by bolt between described flange plate and the flange plate, be provided with diaphragm seal between flange plate and the flange plate.This structure is easy for installation, be connected firmly, the working strength height.
Therefore, the utlity model has material, big, the characteristics such as the pipeline circulating resistance is little, equipment long-time running energy consumption is less, rational in infrastructure, low cost of manufacture of pipeline circulation area of saving.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in Figure of description 1,2,3, a kind of economizing type high pressure pipe line comprises bend pipe 1, threeway 3, and the straight tube of bridge piece 1 and threeway 3, threeway 3 and straight tube are provided with flange plate, and straight tube and threeway 3 are connected by flange plate, between flange plate and the threeway by being threaded.Straight tube by take over 4 and the screw thread short tube 2 that is provided with flange plate 5 form, between flange plate 5 and the screw thread short tube 2 by being threaded.Be connected by bolt between flange plate and the flange plate, be provided with diaphragm seal between flange plate and the flange plate.Take over 4 and screw thread short tube 2 between by being welded to connect, bend pipe and take over 4 between by being welded to connect, the wall thickness of bend pipe 1, threeway 3 and screw thread short tube 2 equates and greater than the wall thickness of taking over 4.The wall thickness of taking over and the ratio of bend pipe or screw thread short tube 2 wall thickness are about 1: 1.3.
Straight tube is made up of the screw thread short tube of taking over and be provided with flange plate, relative less at the adapter wall thickness that screw thread short tube and bend pipe directly are welded to connect with bend pipe, threeway and screw thread short tube, saved material to a great extent, reduced manufacture cost, improved the pipeline circulation area simultaneously, reduced the pipeline circulating resistance.
