Description
Technical field
The utility model belongs to the technical field that condenser is safeguarded, specifically, relates to a kind of Cooling Tubes of Condenser more changing device.
Background technology
Condenser plays Cold source in the thermodynamic cycle of steam-turbine plant, and the cooling tube of conveying condensed water is the critical component of condenser.In condenser transport, installation or running, cooling tube suffers expendable destruction because of X factor, needs the cooling tube being carried out by the cooling tube of breakage removing, more renewing, otherwise fluid bypass flow travels can occur, affect the service behaviour of condenser.But because of structure and the limitations of condenser, inconvenience changes cooling tube by before and after condenser after hydroecium dismounting.
Utility model content
For deficiency above-mentioned in prior art, the utility model provides a kind of Cooling Tubes of Condenser more changing device, and this device both ensure that the normal operation of condenser, solves again the replace tubes problem after Cooling Tubes of Condenser breakage.
In order to achieve the above object, the solution that the utility model adopts is: a kind of Cooling Tubes of Condenser more changing device, comprises the end tube sheet of two pieces of parallel alignment, is distributed in some sagging plates, false tube assembly and end blind pipe assembly between two pieces of end tube sheets.End tube sheet and sagging plate are respectively arranged with installing hole; False tube assembly two ends are connected with set bolt, are provided with locked spacer between set bolt and false tube assembly, and described locked spacer diameter is greater than the diameter of installing hole.The some middle false tube that false tube assembly comprises end false tube, afterbody false tube and is fixedly connected between end false tube and afterbody false tube; End false tube and middle false tube are set to the solid tubes of one end strap bolt, another end band screw, and afterbody false tube is set to the solid tubes of two ends all with screw; End false tube, some middle false tubes, afterbody false tube are threaded successively.End blind pipe assembly is arranged in the installing hole of end tube sheet, the plug that end blind pipe assembly comprises titanium pipe and is arranged in titanium pipe.
Further, spring shim is provided with between locked spacer and set bolt.
Further, the threaded connection place of false tube assembly pipe shaft is provided with limit screw.
The beneficial effects of the utility model are, false tube assembly two ends are fixedly connected with locked spacer respectively, prevent false tube assembly axial float significantly; False tube assembly is arranged in the installing hole of sagging plate, prevents the fluid bypass flow travels in housing; End blind pipe assembly is fixedly connected in the installing hole of end tube sheet, prevents the condensed water in cooling tube to enter in condenser shell; The device avoids and hydroecium is carried out dismounting and change cooling tube, save manpower, financial resources and material resources, and do not delay installation and the maintenance process of whole electricity generation system, good economy performance; False tube assembly adopts the combining form be threaded, and substitute mode is simple, short construction period.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
The utility model provides a kind of Cooling Tubes of Condenser more changing device, as shown in Figure 1, comprises the end tube sheet 1 of two pieces of parallel alignment, is distributed in some sagging plates 2, false tube assembly 3 and end blind pipe assembly 4 between two pieces of end tube sheets 1.End tube sheet 1 and sagging plate 2 are respectively arranged with installing hole, and false tube assembly 3 is arranged in the installing hole of sagging plate 2, prevents the fluid bypass flow travels in housing.As shown in Figure 3, false tube assembly 3 two ends are connected with set bolt 5, are provided with locked spacer 6 and spring shim 7 between set bolt 5 and false tube assembly 3, and described locked spacer 6 diameter is greater than the diameter of installing hole, prevents false tube assembly 3 axial float significantly.
As shown in accompanying drawing 1 and accompanying drawing 4, false tube assembly 3 comprises end false tube 31, afterbody false tube 32 and is fixedly connected on the some middle false tube 33 between end false tube 31 and afterbody false tube 32; End false tube 31 and middle false tube 33 are set to the solid tubes of one end strap bolt, another end band screw, and afterbody false tube 32 is set to the solid tubes of two ends all with screw; End false tube 31, some middle false tubes 33, afterbody false tube 32 are threaded successively, and threaded connection place is provided with limit screw 8.Being shorter in length than the spacing of end tube sheet 1 and sagging plate 2, being longer than the spacing of adjacent two pieces of sagging plates 2 of middle false tube 33, be convenient to install in condenser and change, applicability is strong.
As shown in Figure 4, end blind pipe assembly 4 is arranged in the installing hole of end tube sheet 1, and end blind pipe assembly 4 comprises titanium pipe 41 and is arranged on the plug 42 in titanium pipe 41, prevents the condensed water in cooling tube to enter in condenser shell.Whole device avoids and hydroecium is carried out dismounting and change cooling tube, saves manpower, financial resources and material resources, and does not delay installation and the maintenance process of whole electricity generation system, good economy performance; False tube assembly 3 adopts the combining form be threaded, and substitute mode is simple, short construction period.
Installation process: the cooling tube of breakage is extracted out piecemeal, cuts off and clean out, by middle false tube 33 from end tube sheet 1 toward sagging plate 2 poling, be threaded by root, locate with limit screw 8, welding, polishing, after middle false tube 33 all connects, then end false tube 31, afterbody false tube 32 are threaded respectively at middle false tube 33 two ends, then at end false tube 31 and afterbody false tube 32 termination, locked spacer 6, spring shim 7 and set bolt 5 are installed; Mounting end blind pipe assembly 4 in the installing hole of end, two ends tube sheet 1, and expand tube process is carried out to end blind pipe assembly 4, reach shutoff object.
