Description
Technical field
The utility model is related to heat exchange inner tube in a kind of mesohigh freezing type drier bushing type evaporator and exempts from welding
Novel telescopic heat exchanger joint.
Background technology
At present, bushing type evaporator outer tube on the market mainly uses welded seal with inner tube sealing means.For example, freeze
Using the inner tube of bushing type evaporator using 30408 pipes on formula drying machine, outer tube uses copper tube.There is following lack in welding process
Fall into：Welding procedure is complicated, when especially inner and outer pipes material is different, and welding easily leakage defect occurs.In addition, connecing to inner tube
(pressure-bearing pipe) produces heat affecting, causes material mechanical performance to decline.In use, inner tube is as main pressure-bearing pipeline, because pressure
Usually up to tens of MPa, at this pressure inner tube pressure-bearing and not pressure-bearing situation, can all there is caliber alternately change.Through it is long when
Between use after, when weld seam is stretched extruding, then crack produces seepage probability and is consequently increased.Further, if leaking,
It is cumbersome to need to handle, and can not be repaired in real time, influences the progress of work.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of good sealing effect and is easy to regular maintenance, and
The novel telescopic heat exchanger joint of structure durable.
To achieve the above object, a kind of novel telescopic heat exchanger joint that the utility model is provided, including major joint body,
Inner tube of heat exchanger through major joint body, the heat exchanger outer tube being cased with the inner tube of heat exchanger of major joint body side, connect in master
The sealing device that the inner tube of heat exchanger of head body opposite side is provided with, and the outer tube adapter being provided with major joint body.Major joint body
For the body of threeway.Heat exchanger outer tube is welded with major joint body.Sealing device include major joint side side be provided with gland,
The airtight and watertight padding being filled between gland and major joint body, and provided with being connected with major joint body to airtight and watertight padding precompressed on gland
Tight bolt.Outer tube adapter is welded on major joint body.
The beneficial effects of the utility model are with good sealing effect and are easy to regular maintenance, and structure durable effect.
Because inner tube of heat exchanger is as main pressure-bearing pipeline, play a part of exempting from welding, using weldering between major joint body and heat exchanger outer tube
Connect in succession, outer tube adapter is not directly connected with heat exchanger outer tube, but by welding or being threadedly secured on major joint body, keeps away
Exempted from the problem of mesohigh thin wall tube heat exchanger welding difficulty, and unlike material welding difficulty problem.In addition, airtight and watertight padding by
Effective sealing is issued to pretightning force compressed state.Inner tube of heat exchanger is when working pressure-bearing, and external diameter becomes big, and sealing gasket decrement increases
Greatly, with the more preferable effect of sealing property.If there is trickle seepage, the pre- of airtight and watertight padding can be adjusted by clamping screw
Clamp force reaches leakage-proof effect, can on-bne repair, realize the effect for being easy to regular maintenance and structure durable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is internal structure schematic diagram of the present utility model；
Fig. 3 is the structural representation that Fig. 1 removes major joint body；
Fig. 4 is the structural representation of main fittings body.
Embodiment
Utility model is described in further detail below in conjunction with the accompanying drawings.
As Figure 1-4, a kind of novel telescopic heat exchanger joint, including major joint body 1, changing through major joint body 1
Hot device inner tube 2, the heat exchanger outer tube 3 being cased with the inner tube of heat exchanger 2 of the side of major joint body 1, in the opposite side of major joint body 1
The sealing device 4 that inner tube of heat exchanger 2 is provided with, and the outer tube adapter 5 being provided with major joint body 1.Major joint body 1 is threeway
Body.Heat exchanger outer tube 3 is welded with major joint body 1.Sealing device 4 include the side of major joint body 1 be provided with gland 41, pressure
The airtight and watertight padding 42 being filled between lid 41 and major joint body 1, and on gland 41 provided be connected with major joint body 1 to sealing fill out
Expect the bolt 43 of 42 pre-pressings.Outer tube adapter 5 is welded on major joint body 1.
In use, connecting inner tube of heat exchanger 2 by the major joint body 1 of auxiliary, and main pressure-bearing pipe is used as using inner tube of heat exchanger 2
Road, plays a part of exempting from welding.Afterwards, the sealing function between 3 two pipelines of inner tube of heat exchanger 2 and heat exchanger outer tube is to pass through
The sealed airtight and watertight padding 42 of pre-pressing is provided between major joint body 1 and gland 41 to be sealed.Above-mentioned major joint body 1 is with changing
Using being welded to connect between hot device outer tube 3, outer tube adapter 5 is not directly connected with heat exchanger outer tube 3, but by welding or
It is threadedly secured on major joint body 1.Wherein, the effect of bolt 43 is to adjust joint gland 41 to reach the pretightning force of airtight and watertight padding 42
To the purpose of sealing property.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these belong to practical new
The protection domain of type.
