Abstract
The utility model discloses a frock is preheated in butt joint of tubular product groove, including associative base and support piece, its characterized in that: be fixed with the connecting pipe on support piece, the upper end of connecting pipe and the middle part of arcs of recesses heating pipe connect firmly, and the lower extreme of connecting pipe seals, and the inner chamber of connecting pipe communicates with each other with the inner chamber of arcs of recesses heating pipe, and the both ends of arcs of recesses heating pipe are sealed, are equipped with the fire hole of several equipartition at the medial surface of arcs of recesses heating pipe, and the middle part of connecting pipe is taken over with the gas and is communicated with each other, is equipped with the stop valve on the gas is taken over. Can convenient and fast preheat the tubular product groove, and preheating effect is good is preheated evenly, has promoted labor efficiency, has guaranteed welding quality.
Description
Technical field
This utility model relates to a kind of frock for the docking preheating of tubing groove.
Background technology
In Boiler Manufacture, for the higher tubing groove of material when docking, need in advance groove be preheated, after reaching the preheating temperature of technological requirement, just can carry out welding！Generally manually using heating to rob in actual mechanical process at present to preheat, not only efficiency is low, it is uneven to preheat, and cannot meet welding quality requirement.
Utility model content
For the technical problem of above-mentioned existence, this utility model provides a kind of tubing groove docking preheating frock, and tubing groove can conveniently be preheated by it, and pre-heat effect is good, and preheating uniformly, improves labor efficiency, it is ensured that welding quality.
In order to achieve the above object, a kind of tubing groove docking preheating frock of the present utility model, including the base being connected and support member, it is characterized in that: on support member, be fixed with connecting tube, the upper end of connecting tube and arcs of recesses add the middle part of heat pipe and connect firmly, the lower end closed of connecting tube, the inner chamber of connecting tube adds the inner chamber of heat pipe and communicates with arcs of recesses, arcs of recesses adds the closed at both ends of heat pipe, the medial surface adding heat pipe at arcs of recesses is provided with several uniform fire output hole, the middle part of connecting tube communicates with combustion gas adapter, is provided with stop valve on combustion gas is taken over；
During use, it is first shut off stop valve, natural gas pipe is connected with combustion gas adapter；Then the pipe groove that need to dock being placed on arcs of recesses and add inside heat pipe, several fire output holes, round pipe groove, are slightly turned on stop valve, light the natural gas of fire output hole, control, by adjustable cut-off valve, the size that fires, and so can ensure that and reach to preheat uniform effect；Weld bond docking can be carried out；Tubing groove can conveniently be preheated by this utility model, and pre-heat effect is good, and preheating uniformly, improves labor efficiency, it is ensured that welding quality；
Preferred as one, described support member is a stay tube, and being located at of connecting tube underclearance is propped up in stay tube, is provided with the holding screw compressing connecting tube on a stay tube；By the height of holding screw adjustable connecting tube, use more convenient.
In sum, tubing groove can conveniently be preheated by this utility model, and pre-heat effect is good, and preheating uniformly, improves labor efficiency, it is ensured that welding quality.
Accompanying drawing explanation
Fig. 1 is the front view of this utility model embodiment.
Fig. 2 is the A direction view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Figure 1 to Figure 2, this tubing groove docking preheating frock, including the base 1 being connected and a stay tube 2, being located at of one connecting tube 3 underclearance is propped up in stay tube 2, a stay tube 2 is provided with the holding screw 4 compressing connecting tube 3, the upper end of connecting tube 3 adds the middle part of heat pipe 5 and welds and connect firmly with arcs of recesses, the lower end closed of connecting tube 3, the inner chamber of connecting tube 3 adds the inner chamber of heat pipe 5 and communicates with arcs of recesses, arcs of recesses adds the closed at both ends of heat pipe 5, the medial surface adding heat pipe 5 at arcs of recesses is provided with several uniform fire output hole 6, the middle part of connecting tube 3 communicates with combustion gas adapter 7, combustion gas adapter 7 is provided with stop valve 8；
During use, it is first shut off stop valve 8, natural gas pipe and combustion gas adapter 7 are connected；Then the pipe groove that need to dock is placed on arcs of recesses and adds inside heat pipe 5, several fire output holes 6, round pipe groove, are slightly turned on stop valve 8, light the natural gas of fire output hole, control, by adjustable cut-off valve 8, the size that fires, so can ensure that and reach to preheat uniform effect；Weld bond docking can be carried out；Tubing groove can conveniently be preheated by this utility model, and pre-heat effect is good, and preheating uniformly, improves labor efficiency, it is ensured that welding quality；By the height of holding screw 4 adjustable connecting tube 3, use more convenient.
