Description
Technical field
Fixed connection structure when the present invention relates to heat exchanger pressure testing between tube sheet and shell-side cylinder.
Background technology
The structure of heat exchanger mainly comprises: shell-side cylinder, the head outer end of shell-side cylinder is provided with the tube sheet being with some pores, the head of shell-side cylinder is provided with mounting flange, the outer end of tube sheet is provided with bobbin carriage, bobbin carriage is fixedly connected in shell-side cylinder by mounting flange, be provided with some heat exchanger tubes in shell-side cylinder, the pipe end of heat exchanger tube wears and is weldingly fixed in the pore on tube sheet.Make in the process of heat exchanger, need first to carry out pressure testing test to shell-side cylinder, whether the weld seam checking between tube sheet and heat exchanger tube with this has the situation of seepage, does not have to install bobbin carriage again when seepage when between exchanger tubes and tubesheets.Tube sheet sealing is then needed to be fixed in shell-side cylinder during pressure testing test, traditional tube sheet and being fixedly connected with between shell-side cylinder are the pressure testing flanges matched by other manufacture and installation flange, during pressure testing test, pressure testing flange is arranged on tube sheet outer and be fixedly connected with the mounting flange in shell-side cylinder.The shortcoming of the fixed connection structure between above-mentioned pressure testing tube sheet and shell-side cylinder is: the shell-side cylinder of different size model then needs the pressure testing flange making different size model, pressure testing flange can not be reused, thus causes heat exchanger cost of manufacture higher.
Summary of the invention
The object of the invention is: a kind of fixed connection structure that can be applicable between the pressure testing tube sheet of different specification size shell-side cylinder and shell-side cylinder is provided.
For achieving the above object, the technical solution used in the present invention is: fixed connection structure during pressure testing between tube sheet and shell-side cylinder, comprise: shell-side cylinder, the head outer end of shell-side cylinder is provided with tube sheet, the head of shell-side cylinder is provided with mounting flange, some fastening assemblies are provided with between tube sheet and mounting flange, described fastening assembly is distributed on tube sheet and mounting flange circumferentially, the structure of single fastening assembly comprises: depression bar, one end of depression bar is provided with the top grab of bending downwards, depression bar is provided with through hole, montant is provided with in through hole, the bottom of montant is provided with the bottom grab upwards bent, the threaded upper ends section of the montant outside through hole is provided with locking nut, tighten the locking nut in each fastening assembly respectively, can make that the top grab in each fastening assembly and bottom grab are corresponding is respectively clamped on the top of tube sheet and the bottom of mounting flange, thus tube sheet and mounting flange are fixed.
Further, fixed connection structure during aforesaid pressure testing between tube sheet and shell-side cylinder, wherein, the outer end of each depression bar is provided with retaining wall straight down, and retaining wall gear leans against outside montant.
Further, fixed connection structure during aforesaid pressure testing between tube sheet and shell-side cylinder, wherein, is positioned in each fastening assembly on the depression bar outside montant and is all connected with oblique bracing piece.
Advantage of the present invention is: simple and practical, by evenly installing some fastening assemblies on tube sheet and mounting flange during pressure testing, thus tube sheet and mounting flange is mutually permanently connected; After pressure testing completes, the fastening assembly disassembled can also use when the shell-side cylinder pressure testing of other any different specification size, and fastening assembly can constantly be reused, thus greatly reduces the cost of manufacture of heat exchanger.
Accompanying drawing explanation
The structural representation of fixed connection structure when Fig. 1 is pressure testing of the present invention between tube sheet and shell-side cylinder.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the present invention is described in further detail.
As shown in Figure 1, fixed connection structure during pressure testing between tube sheet and shell-side cylinder, comprise: shell-side cylinder 1, the head outer end of shell-side cylinder 1 is provided with tube sheet 2, the head of shell-side cylinder 1 is provided with mounting flange 3, some fastening assemblies are provided with between tube sheet 2 and mounting flange 3, described fastening assembly is distributed on tube sheet 2 and mounting flange 3 circumferentially, the structure of single fastening assembly comprises: depression bar 4, one end of depression bar 4 is provided with the top grab 41 of bending downwards, depression bar 4 is provided with through hole, montant 6 is provided with in through hole, the bottom of montant 6 is provided with the bottom grab 61 upwards bent, the threaded upper ends section of the montant 6 outside through hole is provided with locking nut 62, tighten the locking nut 62 in each fastening assembly respectively, the top grab 41 in each fastening assembly and bottom grab 61 can be made to be clamped on the top of tube sheet 2 and the bottom of mounting flange 3 respectively, thus tube sheet 2 and mounting flange 3 are fixed.In the present embodiment, the outer end of each depression bar 4 is provided with retaining wall 42 straight down, and retaining wall 42 gear leans against outside montant 6, and the effect arranging grade wall 42 is used to prevent montant 6 from outwards sliding.The depression bar 4 being positioned at outside montant 6 in each fastening assembly is all connected with oblique bracing piece 5, thus enhances the strength and stability of depression bar 4.
Advantage of the present invention is: simple and practical, by installing some fastening assemblies on tube sheet 2 and mounting flange 3 during pressure testing, tighten the locking nut 62 in each fastening assembly, the top grab 41 in each fastening assembly and bottom grab 61 can be made to be clamped on the corresponding top of tube sheet 2 and the bottom of mounting flange 3 respectively, thus tube sheet 2 and mounting flange 3 are mutually permanently connected, this syndeton is reliable; After pressure testing completes, the fastening assembly disassembled can also use when shell-side cylinder 1 pressure testing of other any different specification size, and fastening assembly can be reused, and greatly reduces the cost of manufacture of heat exchanger.
