Abstract
The utility model relates to a kind of welder of flange of the conduit coupling without argon shield, it is characterized by it and comprises welding base, annular solder pressing plate, pressure plate cushion block and ceramic substrate; There is annular flange flange in the centre of welding base, outside annular flange flange, be provided with an annular groove; Pressure plate cushion block is arranged on welding base, and annular solder pressing plate is installed and is connected on pressure plate cushion block, in annular groove, be provided with ceramic substrate.The advantage that the utility model has does not need pure argon to protect when the flange of welded pipe line connector, and welding cost is low.
Description
Technical field
The utility model relates to a kind of welder, particularly relates to a kind of welder of flange of the conduit coupling without argon shield.
Background technology
Be welded flange (welding neck collar) and be usually used in medium temperature and pressure is not high and in the pressure pipeline that corrosive medium is stronger.When corrosive medium is stronger, the part (flange) of flange contact medium is for corrosion resistant high-grade material is as materials such as stainless steels, and outside then utilizes low grade material such as the flange ring of carbon steel material to clamp it to realize sealing; So just can reduce the cost of whole piece pipeline.Chinese patent 2010102801735 discloses a kind of welder of flange of conduit coupling, it is characterized by it and comprises welding base, annular solder pressing plate, pressure plate cushion block and appendix; There is annular flange flange in the centre of welding base, outside annular flange flange, be provided with an annular groove; Annular solder pressing plate is installed and is connected on welding base; gas distribution channel is provided with in welding base; one end of gas distribution channel is communicated with appendix; the other end of gas distribution channel communicates with annular groove; its flange be welded (welding neck collar) is owing to being all the special material such as stainless steel or copper alloy, nickel-base alloy, Hastelloy; need applying argon gas to protect when bottoming is welded, the special material such as Hastelloy more needs high-purity argon gas to protect, and this adds welding cost undoubtedly.
Summary of the invention
For above-mentioned shortcoming, the purpose of this utility model is the welder of the flange providing a kind of conduit coupling without argon shield, does not need pure argon to protect during its flange at welded pipe line connector.
Technology contents of the present utility model is, a kind of welder of flange of the conduit coupling without argon shield, it is characterized by it and comprises welding base, annular solder pressing plate, pressure plate cushion block and ceramic substrate; There is annular flange flange in the centre of welding base, outside annular flange flange, be provided with an annular groove; Pressure plate cushion block is arranged on welding base, and annular solder pressing plate is installed and is connected on pressure plate cushion block, in annular groove, be provided with ceramic substrate.
The utility model is compared with prior art had is a little: utilize ceramic substrate to instead of original argon shield, make thus welding equipment structure simple, easy to maintenance, be easy to operation, also make welding cost greatly reduce.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of welder of flange of the conduit coupling without argon shield, is characterized by it and comprises welding base 1, annular solder pressing plate 2, pressure plate cushion block 3 and ceramic substrate 4; There is annular flange flange 1.1 in the centre of welding base 1, outside annular flange flange 1.1, be provided with an annular groove 1.2; Pressure plate cushion block 3 is arranged on welding base 1, and annular solder pressing plate 2 is installed and is connected on pressure plate cushion block 3, is provided with ceramic substrate 4 in annular groove 1.2.
Operation principle of the present utility model is: the middle annular flange flange 1.1 of welding base 1 is inserted in the adapter 5 will welding flange, and the flange 6 that will weld is placed on and welds on base 1 and be enclosed within outside adapter 5; Annular solder pressing plate 2 on flange 6 limit press-fits at annular solder pressing plate 2 arranged outside pad pressure plate cushion block 3, adjustment is welded the welded gaps 7 of flange overlap edge and adapter, even to surrounding welded gaps 7, the ceramic substrate 4 in annular groove 1.2 aims at welded gaps 7; Tight a bolt and 8 make annular solder pressing plate 2 compress flange 6; Spot welding is welded flange 6 and adapter 5.
