Description

A kind of welding tooling of high back pressure condenser expansion joint

Technical field

The utility model is related to condenser field, more particularly to a kind of welding tooling of high back pressure condenser expansion joint.

Background technology

At present, China's electric system is still high energy consumption industry, and the energy-saving of electric system is China's energy-saving and emission-reduction Important channel.And cogeneration of heat and power is one of energy-saving important channel of electric system, the wherein energy-saving effect of high back pressure heat supply Significantly.Condensing-type unit, high back pressure heat supply heat heat supply network recirculated water by improving low pressure (LP) cylinder exhaust steam pressure and exhaust temperature Reach heat supply purpose.

With the upgrading that national energy-saving emission reduction requires, the ideal high back pressure condenser heat supply of energy-saving effect is promoted rapidly It comes, so-called high back pressure condenser heat supply is exactly that municipal heat supply hot net water introducing condenser is made full use of the weary of turbine discharge Heat heating hot net water.High back pressure condenser when being welded at the scene with expansion joint usual leg highly reach 20mm, in welding process In easily base material is caused to deform, causing the use quality of high back pressure condenser reduces, reduced service life.

Utility model content

The purpose of this utility model is that solve the residue that base material is easily caused to deform and weld in the welding process not Tractable problem provides a kind of welding tooling of high back pressure condenser expansion joint.

The technical solution adopted in the utility model is as follows：

A kind of welding tooling of high back pressure condenser expansion joint, which is characterized in that including sheath, the sheath includes upper Sheath and lower jacket, the upper jacket and lower jacket are disposed as two, are provided with and are contained at slag between described two lower jackets, institute It states upper jacket and lower jacket matches two-by-two, upper jacket is connected with lower jacket by connection structure, the nearly weld end of the sheath It is both provided with cooling zone.

Further, the sheath is tubbiness or horn-like.

Further, the connection structure is fixed or other fixed structures for bolt.

Further, the upper jacket and lower jacket are using alloy type hard material, and the semi-ring size of the sheath is than expansion Weld big 3cm~6cm of section, it is bigger than expansion joint, it can be rotated in welding.

Further, it is welded to connect between two lower jackets at the Sheng slag, by containing at slag directly by two lower jackets Relative position be fixed.

In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are：

1. the auxiliary welding tool of the utility model design can be protected base material in the welding for carrying out expansion joint Shield so that base material is unlikely to deform, and influences the use of expansion joint；

2. the cooling zone that the utility model uses can will cool down spark for splashing in welding process etc. so that weldering The temperature at the place of connecing does not diffuse into base material, further protects base material；

3. the utility model uses tubbiness or horn-like, the spark of splashes is completely cut off except base material so that entire Welding process can directly concentrate on the process problem welded without worrying spark；

4. the utility model design is contained at slag, the residue generated during welding can be collected；

5. the sheath of the utility model is dimensioned to bigger 3cm~6cm than weld, fine rotation can be carried out, it will not Connecting rod is allowed to influence welding process.

Description of the drawings

The utility model will illustrate by example and with reference to the appended drawing, wherein：

Fig. 1 is the structure diagram of the utility model；

Fig. 2 is the side view of the utility model.

It is marked in figure：1- upper jackets, 2- lower jackets, 3- cooling zones, 4- are contained at slag, 5- connection structures.

Specific embodiment

All features or disclosed all methods disclosed in this specification or in the process the step of, in addition to mutually exclusive Feature and/or step other than, can combine in any way.

It elaborates with reference to Fig. 1, Fig. 2 to the utility model.

A kind of welding tooling of high back pressure condenser expansion joint, which is characterized in that including sheath, the sheath includes upper Sheath 1 and lower jacket 2, the upper jacket 1 and lower jacket 2 are disposed as two, and Sheng slag is provided between described two lower jackets 2 Place 4, the upper jacket 1 and lower jacket 2 match two-by-two, and upper jacket 1 and lower jacket 2 are connected by connection structure 5, the sheath Nearly weld end is both provided with cooling zone 3.

Further, the sheath is tubbiness or horn-like.

Further, the connection structure 5 is fixed or other fixed structures for bolt.

Further, the upper jacket 1 and lower jacket 2 use alloy type hard material, and the semi-ring size of the sheath is than swollen Weld big 3cm~6cm of swollen section, it is bigger than expansion joint, it can be rotated in welding.

Further, it 4 is welded to connect between two lower jackets 2 at the Sheng slag, will directly be protected under two by containing at slag 4 The relative position of set 2 is fixed.

The occupation mode of the utility model：As shown in Figures 1 and 2, two lower jackets 2 are welded and fixed by containing at slag 4, In use, following entirety is placed under the weld of expansion joint and condenser, then two upper jackets 1 are passed through into connection structure 5 It is fixed on corresponding lower jacket 2, expansion joint and condenser are in the cylinder of lower jacket 2 and the composition of upper jacket 1 at this time, then into Row welding, in the welding process, can carry out fine rotation, and 4 relative positions with weld are contained at slag in adjustment.
