Abstract
The utility model discloses a fixed connecting structure between a tube plate and shell pass cylinders during pressure test. The fixed connecting structure can be applicable to shell pass cylinders of different specifications and sizes, and comprises a shell pass cylinder, wherein a tube plate is arranged at the outer end of the head of the shell pass cylinder; a mounting flange is arranged at the head of the shell pass cylinder; multiple fastening components are arranged between the tube plate and the mounting flange; and the fastening components are uniformly distributed on the circumferences of the tube plate and the mounting flange. A single fastening component comprises a pressing rod, wherein an upper clamping hook which is bent downwards is arranged at one end of the pressing rod, a through hole is formed in the pressing rod, a vertical rod is arranged in the through hole, a bottom clamping hook which is bent upwards is arranged at the bottom of the vertical rod, and a locking nut is arranged on a threaded section of the upper end of the vertical rod outside the through hole; and the locking nut in each fastening component is respectively screwed, so that each upper clamping hook and each bottom clamping hook are respectively and correspondingly clamped on the top of the tube plate and the bottom of the mounting flange, and the tube plate and the mounting flange are fixed.
Description
Technical field
Fixed connection structure when the utility model 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 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, in shell-side cylinder, be provided with some heat exchanger tubes, 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 shell-side cylinder, carry out pressure testing test, with this, check that whether weld seam between tube sheet and heat exchanger tube has the situation of seepage, installs bobbin carriage in the situation that there is no seepage between heat exchanger tube and tube sheet again.During pressure testing test, need tube sheet sealing to be fixed in shell-side cylinder, being fixedly connected with between traditional tube sheet and shell-side cylinder is the pressure testing flange matching with mounting flange by other making, during pressure testing test, pressure testing flange is arranged on outside tube sheet and is fixedly connected with the mounting flange in shell-side cylinder.Above-mentioned pressure testing is by the shortcoming of the fixed connection structure between tube sheet and shell-side cylinder: the shell-side cylinder of different size model needs to make the pressure testing flange of different size model, pressure testing flange can not be reused, thereby causes heat exchanger cost of manufacture higher.
Utility model content
The purpose of this utility model is: a kind of fixed connection structure between tube sheet and shell-side cylinder for pressure testing that can be applicable to different specification size shell-side cylinder is provided.
For achieving the above object, the technical solution adopted in the utility model 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, between tube sheet and mounting flange, be provided with some fastening assemblies, described fastening assembly is distributed on the circumference of tube sheet and mounting flange, the structure of single fastening assembly comprises: depression bar, one end of depression bar is provided with the top grab of downward bending, on depression bar, be provided with through hole, in through hole, be provided with montant, the bottom of montant is provided with the upwards bottom grab of bending, the upper end thread segment of the montant outside through hole is provided with locking nut, tighten respectively the locking nut in each fastening assembly, can make that 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, thereby 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 in montant outside and is all connected with oblique bracing piece.
The utility model has the advantages that: simple and practical, during pressure testing, by even on tube sheet and mounting flange, some fastening assemblies are installed, thereby tube sheet and mounting flange are mutually permanently connected; After pressure testing completes, the fastening assembly disassembling can also use when the shell-side cylinder pressure testing of other any different specification size, and fastening assembly can constantly be reused, thereby has greatly reduced the cost of manufacture of heat exchanger.
Accompanying drawing explanation
The structural representation of fixed connection structure when Fig. 1 is pressure testing described in the utility model between tube sheet and shell-side cylinder.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model 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, between tube sheet 2 and mounting flange 3, be provided with some fastening assemblies, described fastening assembly is distributed on the circumference of tube sheet 2 and mounting flange 3, the structure of single fastening assembly comprises: depression bar 4, one end of depression bar 4 is provided with the top grab 41 of downward bending, on depression bar 4, be provided with through hole, in through hole, be provided with montant 6, the bottom of montant 6 is provided with the upwards bottom grab 61 of bending, the upper end thread segment of the montant 6 outside through hole is provided with locking nut 62, tighten respectively the locking nut 62 in each fastening assembly, can make top that top grab 41 in each fastening assembly and bottom grab 61 be clamped on respectively tube sheet 2 and the bottom of mounting flange 3, thus make tube sheet 2 and mounting flange 3 fixing.In the present embodiment, the outer end of each depression bar 4 is provided with retaining wall 42 straight down, and retaining wall 42 gears lean against outside montant 6, and the effect that grade wall 42 is set is for preventing that montant 6 from outwards sliding.On the depression bar 4 that is positioned at montant 6 outsides in each fastening assembly, be all connected with oblique bracing piece 5, thereby strengthened the strength and stability of depression bar 4.
The utility model has the advantages that: simple and practical, during pressure testing by some fastening assemblies being installed on tube sheet 2 and mounting flange 3, tighten the locking nut 62 in each fastening assembly, can make top that top grab 41 in each fastening assembly and bottom grab 61 be clamped on respectively corresponding tube sheet 2 and the bottom of mounting flange 3, thereby tube sheet 2 and mounting flange 3 are mutually permanently connected, and this syndeton is reliable; After pressure testing completes, the fastening assembly disassembling can also use when shell-side cylinder 1 pressure testing of other any different specification size, and fastening assembly can be reused, and has greatly reduced the cost of manufacture of heat exchanger.
