Abstract

The utility model relates to a heat exchange component connection's technical field specifically discloses an oblique stabilizer blade connecting piece for spiral tie, including the columniform connector, and the pin of connector coaxial rotation connection to and a plurality of stabilizer blades of evenly fixing in the connector outside, the free end of pin is equipped with the opening, and the free end of pin still is equipped with and crosses the open -ended screw hole, the stabilizer blade is outer slope of opening from the link to the free end arranges, the free end outside of stabilizer blade is equipped with spacing lug. Adopt above -mentioned scheme, the stabilizer blade is installed in hot exchange pipe more firmly, and the ability of absorb is stronger, has avoided leading to the connecting piece towards askew or wash out because of the rivers sudden turn of events.

Description

Oblique leg connector for spiral band
Technical field
This utility model relates to the technical field that heat exchange elements connects.
Background technology
Heat-exchange tube is one of necessary element in condenser, within being generally mounted to cylinder, and the exchange of heat between two media.For improving the heat transfer effect of heat-exchange tube, generally having flow-disturbing part in heat-exchange tube interpolation, this flow-disturbing part can cause strong flow-disturbing in straight pipeline under airflow function, breaks tube wall retention layer, form turbulent flow, thus play and prevent the attachment of tube wall dirt and the effect of enhanced heat exchange.The spiral tie such as arranged in each heat exchanger tube of Steam Turbine in Fire Power Plant condenser, in-pipe flow can be caused strong interference, break tube wall retention layer, improve heat transfer coefficient by spiral band, reduces gross coal consumption rate amount and electrical generation water consumption.
Spiral band is arranged in heat-exchange tube by connector, tie is connected in the middle part of connector of the prior art, the some legs being evenly arranged in outside tie it are additionally provided with on connector, and the centrage of leg and union joint is parallel, heat-exchange tube put into by tie, leg inserts in heat-exchange tube and the installed surface of leg and heat exchange tube inner wall interference fit, utilize the trickle elastic deformation of leg, the installed surface and the heat exchange tube inner wall that make leg produce larger clamping force and fasten, make connector be arranged on heat-exchange tube port thus realize tie installation in heat-exchange tube.
The shortcoming of existing connector is: connector is when mounted, in order to ensure interference fit, leg can occur subtle flow in inserting heat-exchange tube, make the generation bending of leg, make the supporting surface unbalance stress contacted of leg and heat exchange tube inner wall, possibly even foot portion leaves heat exchange tube inner wall, causes connecting insecure.When heat exchanger startup-shutdown, liquid in pipe there will be of short duration improper flowing, and the phenomenon of torrent or backflow occur in current, and connector is the most easily rushed askew or is washed out, and causes equipment normally to work.
Utility model content
This utility model is intended to provide a kind of oblique leg connector for spiral band, insecure to solve the connection of current connector, the problem easily dropped.
The oblique leg connector for spiral band in this programme, including cylindrical union joint, union joint rotates coaxially the pin of connection, and some legs being uniformly fixed on outside union joint, the free end of described pin is provided with opening, and the free end of pin is additionally provided with the screwed hole crossing opening；Described leg, from connecting end to free end in being in tilted layout of opening, is provided with spacing block set outside the free end of leg.
Beneficial effect: spiral band inserts in the opening of pin free end, and tie is machined with through hole, by screw also cross the screwed hole on pin and the through hole on tie, tightens screw and realizes the connection of spiral band；；Inwardly the free end of extruding leg is the interior bending deformation of leg generation trace, inserts in heat-exchange tube by leg free end, the lateral surface of the free end i.e. installed surface of leg and heat exchange tube inner wall interference fit；Leg tilts relative to union joint axis and outwards launches, there is trickle interior bending deformation in leg, when spacing block set outside heat-exchange tube port and leg free end offsets, leg installed surface tends to parallel with union joint axis, installed surface and the heat exchange tube inner wall of leg are fitted completely, the installed surface of leg is more uniform by the support force of the inwall of heat-exchange tube, makes stable connection get a promotion.Using such scheme, leg is more firm in being arranged on heat-exchange tube, the ability withstood shocks is higher, it is to avoid cause connector rushed askew or wash out because of the current sudden turn of events.
Further, the angle of the centrage of described leg and union joint is 3.1 °, and after under this angle, connector is installed, the installed surface of leg deformation rear leg and the contact area of heat exchange tube inner wall are maximum, and support force is the most uniform, is more firmly mounted and stablizes.
Further, described union joint is provided with away from one end of leg between the connection end of end cap, union joint and pin to connect rolling bearing.The rolling friction using ball replaces sliding friction, reduces the abrasion between part, and the rotation of pin is more smooth and easy simultaneously.
Further, the quantity of leg is three, ensure that the steadiness of connection while simple in construction.

Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: union joint 1, end cap 11, axle sheet 12, axle sleeve 13, retainer 14, Ceramic Balls 15, leg 2, spacing block set 21, pin 3.
As shown in accompanying drawing 1, Fig. 3 and Fig. 4, the oblique leg connector for spiral band in this programme, including cylindrical union joint 1, pin 3 coaxial mounted with union joint 1, and three legs being uniformly connected to outside union joint 12, the free end of pin 3 is machined with opening, and the free end of pin 3 is also machined with the screwed hole crossing opening；Described leg 2, from connecting end to free end in being in tilted layout of opening, is provided with spacing block set 21 outside the free end of leg 2.
As in figure 2 it is shown, union joint 1 is provided with end cap 11 away from one end of leg 2, the outside of end cap 11 is circular arc；It is machined with inner chamber in union joint 1, pin 3 is arranged in union joint 1 by rolling bearing, rolling bearing includes retainer 14, and the Ceramic Balls 15 being arranged on retainer 14, axle sheet 12 and axle sleeve 13 it is also equipped with in union joint 1, axle sheet 12 is positioned at above Ceramic Balls 15, and axle sleeve 13 is positioned at below Ceramic Balls 15.
The angle of the centrage of leg 2 and union joint 1 is 3.1 °, and after under this angle, connector is installed, leg 2 deforms the installed surface of rear leg 2 and the contact area maximum of heat exchange tube inner wall, is more firmly mounted and stablizes.Spiral band inserts in the opening of pin 3 free end, and tie is machined with through hole, by screw also cross the screwed hole on pin 3 and the through hole on tie, tightens screw and realizes the connection of spiral band；The free end of leg 2 inserts in heat-exchange tube, and leg 2 lateral surface i.e. installed surface and the heat exchange tube inner wall of leg 2 is adjacent to.
