The check plate 8 includes plate body 81, tension spring 82 and baffle 83, offers one on the check plate 8 and opens
Mouthful, the side of the opening is hinged with that shape is identical with opening and size is greater than the baffle 83 being open, the other side of the opening
It is provided with the tension spring 82 of connection plate body 81 and baffle 83, it is one, often that the jacking block 12 is corresponding with the quantity of opening
Under state, tension spring 82 pulls baffle 83 to go out closure of openings between baffle 83 and opening when baffle 83 is contacted with jacking block 12
Existing gap.
In the present embodiment, the check plate 8 on open up through-hole corresponding with 10 quantity of the body of rod and position, the number of through-hole
Amount is two, and the body of rod 10 passes through through-hole, and the internal diameter of hole is greater than the outer diameter 2-5cm of the body of rod 10, in this way, can make non-return
Plate 8 is slidably connected on the body of rod 10 by through-hole.
The bottom end of the check plate 8 is connected with telescoping tube 2, and check plate 8 is by the one side closed of telescoping tube 2.
The top of the fixed frame 1 is equipped with jacking block 12, and when the check plate 8 is contacted with jacking block 12, the check plate 8 is opened
It opens.
The tube wall of the telescoping tube 2 uses double-layer structure, and has a cavity, reference between 2 two sides tube wall of telescoping tube
Fig. 2, specific as follows:
The telescoping tube 2 is constituted by outer wall 2a is nested with inner wall 2b two parts, two end seals of the outer wall 2a and inner wall 2b
A closed cavity is closed and constituted therebetween, liquid or gas medium to be heated can be filled in cavity.
Further, the axial direction on the outer wall 2a and inner wall 2b along telescoping tube 2 has been equidistantly positioned at least one annular
The effect of impression 2c, annular indentation 2c are, fold outer wall 2a and inner wall 2b can along annular indentation 2c, so as to fold
During reduce the axial linear distance of telescoping tube, correspondingly, increase the surface area of telescoping tube 2 in former height, be allowed to
The contact of heat source is more abundant.
Preferably, the annular indentation 2c is 10 ° -170 ° of angle, the both sides at angle can along this annular indentation 2c 10 ° -
170 ° of range interior foldings.
In a preferred embodiment of the invention, the inner wall 2b uses heat-conducting metal material, and copper, aluminum material can be used
Material, while certain bending resistance is had both, since inner wall 2b is directly contacted with heat source, thus heat-conducting metal material can be more preferable
The medium transferred heat in cavity；The outer wall 2a use metallic insulation composite material, such as can be used internal layer be copper,
The robust metallics material such as aluminium, outer layer are the heat-barrier materials such as asbestos, foamed plastics, and ectonexine constitutes metallic insulation composite material, tool
Standby spacing mechanical strength and heat preservation and insulation.
Outlet pipe 5 and water inlet pipe 3 are provided on the telescoping tube 2, and outlet pipe 5 and water inlet pipe 3 are connected to cavity, institute
It states and first check-valve 4 is installed on water inlet pipe 3, second check-valve 6, first check-valve 4 and second are installed on the outlet pipe 5
The flow direction of check-valves 6 is shown in the appended drawing reference of Fig. 2 or Fig. 4, and details are not described herein again.
The one end of telescoping tube 2 far from check plate 8 is connected to the escape pipe of boiler by conduit couplings such as flanges, water inlet pipe
3 are connected to external source, and outlet pipe 5 is connected to extraneous water supplying pipe.
Under the effect of gravity, fold along annular indentation 3 is in contraction-like, the space of cavity to telescoping tube 2 under normality
It is significantly compressed, boiler generates hot gas and enters from the bottom end of telescoping tube 2, and 2 inner space of telescoping tube is filled, due to flexible
There is the barrier of check plate 8 in the other side of pipe 2, and gas can not be discharged, thus can only pass back into boiler or constantly in telescoping tube 2
Interior aggregation, to effectively extend the residence time of gas, simultaneous retractable pipe 2 is as the increase of gas is by contraction-like continuous
It stands upright, space during standing upright in cavity constantly increases, interior to generate negative pressure, effect of the liquid in external atmosphere pressure
Under from water inlet pipe 3 constantly be sent into, so that the filling at water source in cavity is realized, simultaneously because the setting of first check-valve 4, liquid
It can not pass back into water inlet pipe 3.
Inner wall 2b is thermal conductive metallic material, can quickly transfer heat to water source, heat to it, heating time can
Diameter by adjusting telescoping tube 2 changes with length, heating and continuous to drive check plate 8 to move at jacking block 12 to telescoping tube 2,
Under the pressure of jacking block 12, baffle 83 overcomes the tension of the pressure of gas and tension spring 82 in telescoping tube 2, so that baffle 83
Gap is opened, 2 inner and outer air pressure of telescoping tube is constantly balanced by gap at this time, and simultaneous retractable pipe 2 is under the effect of gravity
Continuous to shrink, pressure during contraction in cavity is greater than external atmosphere pressure, thus drive liquid in it constantly from
Outlet pipe 5 is discharged, until telescoping tube 2 moves to lowest part, realizes a circulation.
, by foldable structure, it is lower that telescoping tube 2 can be increased since its straight line height is lower at the initial stage that telescoping tube 2 moves
In height with the contact area of flue gas, no matter to realize that telescoping tube 2 folds or stands upright, the contact area phase with flue gas
It is poor little, to realize preferable heating.
Embodiment two
Embodiment two on the basis of example 1, further:
The annular indentation 2c's is physically provided with a circle annular protrusion 2d, on the one hand the setting of annular protrusion 2d increases
The big length at the place annular indentation 2c, is allowed to more round and smooth, and forced area is bigger, avoids conventional angular structure stress and assemble
Damaged problem is easy in a bit；On the other hand since 2 long-time of telescoping tube can deform under the action of thermal stress, thus annular
Raised 2d increases the length of annular indentation 2c, so as to carry out length compensation to expanding with heat and contract with cold, avoids being broken.
Embodiment three
Embodiment three is on the basis of embodiment one or embodiment two, further:
The outer surface of the body of rod 10 is provided with external screw thread, is rotatably connected on the fixed frame 1 with 10 junction of the body of rod
