Description
Technical field
The present invention relates to a kind of anti-dropout automatic tube-penetrating guide cone, belongs to made of metal shell-and-tube exchanger building technology neck
Domain.
Background technology
Heat exchanger is also known as heat exchanger or heat transmission equipment, is that one kind that the partial heat of hot fluid is passed to cold fluid is set
It is standby.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, is occupied in production important
Status.Heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler etc. in Chemical Manufacture, using more
Extensively.
Heat exchanger species is very much, but can substantially divide three major types according to the principle and mode of cold and hot fluid heat exchange：
That is dividing wall type, hybrid and heat storage type, in three classes heat exchanger, recuperative heat exchanger is most widely used.At present, it is existing at present
It is dividing wall type that the main heat exchanger of technology, which has condenser, reboiler, separating heater, extraction heater etc., its structure master
There are heat exchanger tube, chuck, flange, tube sheet etc., assembling of this structure for heat exchanger tube is a big critical technological point.All the time, work
People are using the method assembling heat exchanger tube of manual work guiding, and not only efficiency of assembling is low, but also waste of manpower.Exchange heat pipe is tried
During pressure, indivedual heat exchanger tubes are there are interior leakage phenomenon, even if can remove the heat exchanger tube of interior leakage, but can not carry out manual work guiding,
Also be difficult to new replacing heat-exchange tube in place, therefore, often using by the method that heat exchanger tube both ends block solve the problems, such as in leakage, this
Sample, not only reduces the heat exchange area of heat exchanger, and have impact on the total quality of equipment.
The content of the invention
The object of the present invention is to provide a kind of anti-dropout automatic tube-penetrating guide cone, is filled with solving existing heat exchanger heat exchanger tube
With difficult, shell side assembling and heat exchanger pressure testing can not be manually oriented to for U-shaped fixed tube sheet type heat exchanger heat exchanger tube
The series of problems that leakage can not be replaced in indivedual heat exchanger tubes, the production efficiency for improving heat exchange equipment and the work for reducing worker are strong
Degree.
Technical scheme is as follows：
The present invention is such a anti-dropout automatic tube-penetrating guide cone, including the turnbuckle being connected through a screw thread and tension
Nut；Guide cone is equipped with turnbuckle, the planar end surface of tightening nut is drawn close in the tapered end face of guide cone；On turnbuckle
Rubber tube is also equipped with, rubber tube one end is flushed with the assembling of guide cone end face, and the other end is supported to the handle step circles of turnbuckle
Face.
Further, the guide cone is equipped with anti-turn screw.
Further, the turnbuckle be equipped be used for anti-turn screw be inserted into and lock groove, for spacing end
Face baffle and the connection screw thread for being connected with tightening nut.
Further, the tightening nut is equipped with a through hole and the circular conical surface easy to guiding.
Compared with prior art, the present invention uses turnbuckle, tightening nut, guide cone, anti-turn screw and rubber tube
Specific combination, have high plasticity using rubber, several part combinations into one there is certain rigidity can lead by more than
To having good plasticity not only but also can prevent being left out and the anti-dropout automatic tube-penetrating guide cone that easily takes out.It is U-shaped to solve shell side
Fixed tube sheet type heat exchanger heat exchanger tube can not manually be oriented to assembling, general fixed heat exchanger heat exchanger tube assembling is tired
Difficult, efficiency of assembling is low and the indivedual heat exchanger tubes of heat exchanger pressure testing in leakage the problem of can not replacing.The mechanism meets heat exchanger
Production need, improve product quality.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
Mark in attached drawing for：1- tightening nuts, 2- guide cones, 3- anti-turn screws, 4- turnbuckles, 5- rubber tubes, 6-
End face baffle, 7- grooves, 8- connection screw threads, 9- through holes, 10- circular conical surfaces,.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples, but not as any limitation of the invention.
Please refer to Fig.1：The device of the invention structure includes tightening nut 1, and tightening nut 1 is equipped withThrough hole 9, draw
Tight nut 1 is connected through a screw thread with turnbuckle 4.Turnbuckle 4, which is equipped with, is used for the groove 7 that anti-turn screw 3 is inserted into.Guide cone
2 with turnbuckle 4 by 3 tightening of anti-turn screw together with.Rubber tube 5 and guide cone 2 are housed on turnbuckle 4.
When it is implemented, turnbuckle 4 and guide cone 2 are made of 40Cr steel, its tensile strength is more than or equal to 805Mp,
Yield strength is more than or equal to 685Mp, and ballistic work of the elongation percentage more than or equal to 14,0 DEG C is more than or equal to 41J, belongs to low-alloy high-strength
Degree is high, has good mechanical performance, certain resistance is run into during poling, is not easy to deform, causes to wear
Pipe has some setbacks.Tightening nut 1 uses No. 45 steel, its hardness is less than about turnbuckle 4, in order to when screwing tightening nut 1 not
As for damaged screw.5 material of rubber tube is industrial common soft rubber tube, its is cheap, and plasticity is high, easy to purchase,
During use, once being subject to tightening nut 1 to pass to the power of guide cone 2, tube wall is squeezed, its diameter expands change immediately
Greatly, once extruding force eliminates, can resile again quickly.Anti-dropout when solving poling by this property and put on
Manage later light taking-up.
When leakage need to change pipe in heat exchanger tube, the tube head of leakage is opened in subdrilling, the heat exchanger tube of leakage is removed from tube bank, then
The device of the invention is installed on new heat exchanger tube, so that it may the new heat exchanger tube is assembled in tube bank, avoids the stifled weldering of tube head, from
And ensure the heat exchange efficiency of heat exchanger.
Contour structures of the present invention are simple, manufacture cost is low, easy to operate, safe and reliable, environmentally-friendly sanitary.By using testing
Card, poling is carried out using the present invention, and poling speed is fast, and to use 4.2 times during manual work guiding, poling quality is good, the present invention
It is entirely capable of the needs for meeting structure heat exchanger manufacture.
The operation principle and implementation steps of the present invention：The anti-dropout automatic tube-penetrating of the present invention is oriented to wimble structure and sees Fig. 1, uses
When, first heat exchange pipe end surfaces externally and internally is cleaned out, must not there are the impurity such as any greasy dirt.Guide cone 2 is inserted into heat exchanger tube
It is interior, then tightening nut 1 is pierced into 1 thin rod ironThrough hole 9 in, adjust good position, screw tightening nut 1 compress rubber
Sebific duct 5, makes its diameter become larger, is radially expanded, so as to be in close contact with heat transfer tube wall, there is provided necessary anticreep power.Treat poling
After, tightening nut 1 is unclamped with same method opposite direction rotation, recovers 5 diameter of rubber tube, further takes out guide cone 2.Peace
3 lower end of anti-turn screw on guide cone 2 must be inserted in the groove 7 of turnbuckle 4, prevent turnbuckle 4 with tensing spiral shell
Mother 1 rotates together.Corresponding anti-dropout automatic tube-penetrating guide cone need to be used during the heat exchanger tube for assembling different size.
It is the concrete application example of the present invention above, the present invention also has others embodiments, all to use equivalent substitution
Or the technical solution that equivalent transformation is formed, all fall within protection domain of the presently claimed invention.
