Abstract
A single pipe free telescopic structure of a high-temperature air preheater relates to a high-temperature air preheater, belongs to the field of connection modes between a heating pipe and a tubular plate and comprises the tubular plate and a heat exchanging plate vertically connected on the tubular plate; a sealing system is arranged between the heat exchanging plate and the tubular plate and comprises a filling top block, a filling box and fillings; the filling top block and the filling box are respectively sleeved outside the heat exchanging pipe, the filling top block is welded on the tubular plate, the filling box is in thread connection on the filling top block, and the fillings are filed between the filling top block and the filling box; at least one installation groove is arranged on the contact face between the filling top block and the heat exchanging pipe, and at least one installation groove is arranged on the contact face between the filling box and the heat exchanging pipe; and seal rings are respectively arranged in the installation grooves of the filling top block and the filling box. The single pipe free telescopic structure of the high-temperature air preheater avoids the incomplete sealing or blocking phenomena easily caused by the connection structure between a pipe fitting and the tubular plate, and solves the problem of difficulty in replacement of the seal rings and the filling box at the same time.
Description
Technical field
The present invention relates in a kind of high-temperature air preheater the technical field of the connected mode between heating tube and the tube sheet.
Background technology
At present, the high-temperature air preheater of institute's publicity, its heating tube structure relative and that tube sheet freely stretches all adopts single packing seal or adopts single filler to add the structure of sealing ring, because equipment operating temperature height, tube sheet and stuffing box are easy to generate irregular expansion, cause sealing not exclusively or be stuck, sealing ring though adding the structure of sealing ring, single filler can make moderate progress, owing to can not be changed inconvenient maintenance, and screw thread is bad easily, and stuffing box also is difficult for changing.
Summary of the invention
The invention provides the free stretching structure of a kind of high-temperature air preheater single tube, purpose is to solve the structure that existing pipe fitting is connected with tube sheet and easily causes sealing incomplete or stuck phenomenon, solves the not easily changeable defective of sealing ring and stuffing box simultaneously.
The present invention includes tube sheet, heat exchanger tube, described heat exchanger tube is vertically connected on the described tube sheet, between described heat exchanger tube and tube sheet, sealing system is set, described sealing system comprises the filler jacking block, stuffing box, filler, described filler jacking block, stuffing box is nested with respectively outside described heat exchanger tube, described filler jacking block is welded on the described tube sheet, described stuffing box is threaded on the described filler jacking block, described filler is filled between described filler jacking block and the stuffing box, at described filler jacking block mounting groove at least is set on the surface of heat exchanger tube contact, at described stuffing box mounting groove at least is set on the surface of heat exchanger tube contact, at described filler jacking block, in each mounting groove on the stuffing box sealing ring is set respectively.
On pore, all be provided with sealing system on the tube sheet of the present invention, on the contact-making surface of the contact-making surface of filler jacking block and heat exchanger tube and stuffing box and heat exchanger tube, all have the multiple tracks mounting groove now, and be respectively equipped with sealing ring in each mounting groove, this set has been realized secondary seal; At high temperature simultaneously; airtight and watertight padding damages through regular meeting; after filler damages; screw off stuffing box, change filler and get final product, change the sealing ring on the stuffing box simultaneously; reinstall and get final product; as stuck phenomenon or seal structure damage appear, and remove the angle welding of filler jacking block and tube sheet, can take off hermetically-sealed construction and adjust and change.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Among the figure, 1, tube sheet, 2, heat exchanger tube, 3, sealing system, 4, the filler jacking block, 5, stuffing box, 6, filler, 7, mounting groove, 8, sealing ring.
The specific embodiment
As shown in Figure 1, the free stretching structure of this high-temperature air preheater single tube, comprise tube sheet 1, heat exchanger tube 2, heat exchanger tube 2 is vertically connected on the tube sheet 1, between heat exchanger tube 2 and tube sheet 1, sealing system 3 is set, sealing system 3 comprises filler jacking block 4, stuffing box 5, filler 6, filler jacking block 4, stuffing box 5 is nested with respectively outside heat exchanger tube 2, filler jacking block 4 is welded on the tube sheet 1, stuffing box 5 is threaded on the filler jacking block 4, filler 6 is filled between filler jacking block 4 and the stuffing box 5, at filler jacking block 4 mounting groove 7 at least is set on the surface of heat exchanger tube 2 contacts, at stuffing box 5 mounting groove 7 at least is set on the surface of heat exchanger tube 2 contacts, at filler jacking block 4, in each mounting groove 7 on the stuffing box 5 sealing ring 8 is set respectively.
Claims (1)
