Abstract
The utility model discloses a novel shower double-flange connects, including the straight tube, the periphery of straight tube is fixed with the lower flange, and the periphery cover of straight tube is equipped with the flange, goes up the flange and is located the left side of straight tube, and the left end face of straight tube is equipped with the anti-disengaging structure who prevents that the flange from deviating from the straight tube. The utility model discloses simple structure, convenient actual installation.
Description
Technical Field
The utility model belongs to the technical field of the shower technique among the desulfurization system and specifically relates to a novel shower double-flange connects.
Background
In the desulfurization project, FRP spray pipes are generally used as the most critical spray layer equipment in the absorption tower. The material not only reduces the cost, but also ensures the corrosion resistance and the integral mechanical property.
At present, when a double-flange joint connected with a sleeve flange and an expansion joint of an absorption tower is manufactured for an FRP (fiber reinforced plastic) spray pipe, a process of directly pasting two corresponding flanges on a section of pipeline is adopted, the two flanges of the manufactured joint are fixed, as shown in the attached drawing 1, an upper flange 3 and a lower flange 2 are relatively fixed with a straight pipe 1, the situation of bolt hole dislocation is frequently encountered in the installation process, the adjustment and the modification can be carried out only in a drilling and reaming mode, the field construction period is delayed, and the strength of the flanges is damaged. Such problems are more frequent when a retrofit project is encountered where the casing is worn.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned prior art not enough, provide a novel shower double flange connects.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a novel shower double flange connects, includes the straight tube, and the periphery of straight tube is fixed with the lower flange, and the periphery cover of straight tube is equipped with the flange, goes up the flange and is located the left side of straight tube, and the left end face of straight tube is equipped with the anti-disengaging structure who prevents to go up the flange and deviate from the straight tube.
The anti-disengaging structure is a baffle ring, the baffle ring is fixed with the left end face of the straight pipe, and the outer diameter of the baffle ring is larger than the inner diameter of the upper flange.
The utility model has the advantages that: the lower flange and the straight pipe are fixed, the upper flange and the straight pipe can rotate at any angle, when the lower flange and the straight pipe are installed, the lower flange and the pipe on one side are connected firstly, the upper flange rotates at a certain angle when being connected with the pipe on the other side, bolt holes in the upper flange are guaranteed to be aligned with bolt holes in the flange on the other side, the field fault tolerance rate is improved, the installation efficiency is improved, and the strength of the flange is guaranteed.
Drawings
FIG. 1 is a schematic structural view of a prior art double flange joint;
FIG. 2 is a schematic structural view of the present invention;
fig. 3 is a schematic view of the installation of the present invention;
in the figure: straight pipe 1, lower flange 2, upper flange 3, baffle ring 4, circulating pipe 5, sleeve 6 and absorption tower 7
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in figure 2, the novel spray pipe double-flange joint comprises a straight pipe 1, wherein a lower flange 2 is fixed on the periphery of the straight pipe 1, an upper flange 3 is sleeved on the periphery of the straight pipe 1, the upper flange 3 is located on the left side of the straight pipe 1, and an anti-falling structure for preventing the upper flange 3 from falling off from the straight pipe 1 is arranged on the left end face of the straight pipe 1. The anti-falling structure is preferably a baffle ring 4, the baffle ring 4 is fixed with the left end face of the straight pipe 1, and the outer diameter of the baffle ring 4 is larger than the inner diameter of the upper flange 3.
As shown in figure 3, when the device is installed, the right end of the straight pipe 1 firstly extends into the absorption tower 7, the lower flange 2 and the sleeve 6 on the absorption tower 7 are fixed through bolts, then the upper flange 2 is rotated, the screw hole of the upper flange 2 is aligned to the flange hole on the circulating pipe 5, the bolts are threaded and fastened, the field fault tolerance rate is improved, the installation efficiency is improved, and the flange strength is ensured.
Make the utility model discloses a way of double flange joint as follows: firstly, manufacturing a corresponding upper flange 3 mould, pasting a baffle ring 4 at one end of a straight pipe 1, assembling and sleeving the upper flange 3 into the baffle ring 4, then placing the straight pipe on a lower flange 2 mould, pasting a lower flange 2, and cooling and solidifying after the manufacturing is finished.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
