Description
Technical field
Heat-exchanger rig maintenance field is the utility model is related to, more particularly to a kind of heat exchanger poling guide device.
Background technology
Traditional pipe penetration method, problems be present in the operating process of reality.Due to tube sheet and the pore of deflection plate
Processing is there is certain deviation, and in stand assembling process, tube sheet and deflection plate can also produce certain deviation, especially baffling
When plate quantity is more, degreeof tortuosity caused by the tube bank skeleton of assembling can be increased further, cause the position of corresponding pore can not
With one heart.Plus heat exchanger tube leading portion natural bow and itself distortion so that poling work become very difficult, withstood often or
Person blocks.Pipe is longer, and diameter is smaller, and poling is just further difficult.Therefore in poling, it has to which more people coordinate, often back and forth
Firmly reverse, it is also necessary to which someone's tube head position guides frequently so that poling work is not only wasted time and energy, and exchanges the damage of heat pipe
Wound also can hardly be avoided.
The content of the invention
The difficult skill of poling in the pore on by each deflection plate and tube sheet be present to solve heat exchanger tube in the utility model
A kind of art problem, there is provided heat exchanger poling guide device.
Technical scheme is used by the utility model：A kind of heat exchanger poling guide device, including guide cone, centering
Cone, and fastener；The centering cone is fixedly connected on the afterbody axis of guide cone；The fastener includes compressing spiral shell
Mother, axle sleeve, sealing block, locking head and locking nut；Clamp nut is screwed on the outside of the connecting portion of the guide cone and centering cone,
Against clamp nut be sequentially arranged with axle sleeve, sealing block in the outside of centering cone and for the spacing locking head of sealing block and
Locking nut.
The course of work of the present utility model is as follows：Before poling, poling guide device afterbody is gently inserted into heat exchanger tube front end,
Clamp nut is rotated, promotes axle sleeve to enter into heat exchanger tube, so as to push sealing, makes its expansion, is tightly pasted with heat transfer tube wall
Close, so can effective cushion impact forces, prevent seeker from being slipped forward due to inertia during poling.Poling is in place
Afterwards, clamp nut need only be rotated backward, promote axle sleeve moved to outside heat exchanger tube, so as to unclamp sealing block, make guide device with
Heat transfer tube wall separates, and can smoothly take out guide device.
The utility model has the advantages that compared with prior art：
The compositions such as clamp nut, axle sleeve, sealing block, locking head, locking nut and heat exchanger tube fastener, use can lead to
Cross compress nut condition expansion fastening device, by clamp nut rotation control seeker and heat exchanger tube be adjacent to and pine
Open；
Guide cone front portion uses pyramidal structure, ensures the pore that pipe smoothly enters on each deflection plate and tube sheet；
The center line of centering cone guarantee guide cone and heat exchanger tube is on same straight line.
The device passes through test of many times, fullys meet design requirement, changes traditional artificial pipe penetration method, carries significantly
High poling efficiency.Pipe can uninterruptedly pass through each layer baffling by the guiding of inertia impact and seeker forward
Plate and tube sheet, while save labour and time so that poling work becomes efficient.
Brief description of the drawings
Fig. 1 is the cross-sectional view of heat exchanger poling guide device described in the utility model.
Marked in figure as follows：
1- guide cones, 2- clamp nuts, 3- axle sleeves, 4- centering cones, 5- sealing blocks, 6- locking heads, 7- locking nuts.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
Embodiment 1
A kind of heat exchanger poling guide device, including guide cone 1, centering cone 4, and fastener；The centering cone 4 is fixed
It is connected on the afterbody axis of guide cone 1；The fastener includes clamp nut 2, axle sleeve 3, sealing block 5, locking head 6 and locking
Nut 7；The guide cone 1 on the outside of the connecting portion of centering cone 4 with screwing clamp nut 2, in the outside of centering cone 4 against compression
Nut 2 is sequentially arranged with axle sleeve 3, sealing block 5 and for the locking head 6 and locking nut 7 spacing to sealing block.
The front portion of the guide cone 1 is taper, and rear end forms extension along its center axis；The inside edge of guide cone 1
Its center is provided with axis hole；The front end of the guide cone 1 is stretched into axis hole and fixed.
Guide cone front portion uses pyramidal structure, ensures the pore that pipe smoothly enters on each deflection plate and tube sheet.
The center line of centering cone guarantee guide cone and heat exchanger tube heat exchanger poling guide device on same straight line is being entered
During row heat exchanger tube poling, concrete operations are as follows：
1. before poling, poling guide device afterbody is gently inserted into heat exchanger tube front end, rotates clamp nut 2, promotes axle sleeve 3
Enter into heat exchanger tube, so as to push sealing 5, make its expansion, be tightly bonded with heat transfer tube wall, so can effectively buffer punching
Power is hit, prevents seeker from being slipped forward due to inertia during poling.
2. during poling, guide cone 1 is anterior to use pyramidal structure, pipe automatic guide can be entered into each deflection plate and tube sheet
On pore；The center for making leading head for through pipe of centering cone 4 is consistent with heat exchange tube hub.
3. poling in place after, clamp nut 2 need only be rotated backward, promote axle sleeve 3 moved to outside heat exchanger tube, so as to unclamp
Sealing block 5, makes guide device be separated with heat transfer tube wall, can smoothly take out guide device.
