Description
Technical field:
The utility model relates to a kind of connection distribution integrated device of gas house, particularly relates to combustion gas and concentrates distribution manifold.
Background technique:
All need to use concentrated distribution manifold in the connection process of gas house, concentrated distribution manifold comprises intake manifold, prop up suction tude and screwed pipe joint, between bronchus and total inlet pipe, between screwed pipe joint and a suction tude, Placement is all direct butt welding connection, example is welded as with docking between suction tude with screwed pipe joint, concrete grammar first on the precalculated position of a suction tude, processes the prefabricated inlet hole suitable with the endoporus of screwed pipe joint, then by manual for the endoporus of the screwed pipe joint prefabricated inlet hole aimed in a suction tude, together with the excircle part of screwed pipe joint and a suction tude being docked is welded into by seal welding mode.The Placement of propping up between suction tude and total inlet pipe is also like this.Certainly, total inlet pipe directly welds screwed pipe joint too.
There is following defect in this welded structure of docking between screwed pipe joint with suction tude:
First, weld between screwed pipe joint with suction tude and can not ensure the axis of screwed pipe joint and the axes normal of suction tude, make gas meter can not be in precalculated position after mounting, cannot meet the technical requirements that gas meter setting height(from bottom) is consistent, prior art disqualification rate is 25% ~ 30%.
The second, the welding quality between screwed pipe joint and suction tude is difficult to control, and easily occurs rosin joint, not only affects the join strength between screwed pipe joint and suction tude, also there is gas leakage hidden danger.
3rd, welding processing difficulty is large, complicated frock clamping must be used, fixing suction tude is not only needed also to want retaining thread pipe joint, otherwise just can not ensure both relative positions, if the relative position between hand determination screwed pipe joint and suction tude just must be relied on without frock clamping, this mode is more difficult to ensure card, very easily cause welding dislocation, prefabricated inlet hole in the endoporus of screwed pipe joint and suction tude is misplaced, reduce air inlet area, prefabricated inlet hole in suction tude can be produced time serious and expose, cause whole combustion gas to concentrate distribution manifold to scrap.Not only welding quality can not ensure, and manufacturing efficiency is low.
4th, suction tude is welded several screwed pipe joints, and them can be made all to be in same plane, difficulty is very large, cannot ensure that all gas meters are all in this technical requirements in same plane.
Gas company is very high to the height of gas meter in gas meter box installation height conformity and table case, spacing technical requirement, concentrate in distribution integrated device at existing gas meter, the welding connection structure between screwed pipe joint and suction tude is difficult to meet this technical requirements.
Model utility content:
The purpose of this utility model is to provide a kind of screwed pipe joint location sealing welded structure of combustion gas header, it can ensure that all screwed pipe joints are all in same plane, the axis that can ensure again each screwed pipe joint all with the axes normal of suction tude, be more conducive to form sealability between each screwed pipe joint and suction tude better, the welded structure that intensity is higher, can improve the welded seal performance between screwed pipe joint and suction tude and intensity further.
The technological scheme that the utility model is taked is:
A kind of screwed pipe joint location sealing welded structure of combustion gas header, comprise suction tude and screwed pipe joint, screwed pipe joint is fixed in suction tude by welding manner, the endoporus of screwed pipe joint and the endoporus of suction tude interlink, it is characterized in that: the fixing welded structure between screwed pipe joint and suction tude is: in suction tude, compartment of terrain is provided with air outlet hole vertically, the axis of all air outlet holes is all in same plane, and the axes normal of the axis of air outlet hole and suction tude, described air outlet hole is by location fit hole, positioning step hole and bevel for welding hole composition, location fit hole is coaxial with positioning step hole, positioning shaft rank and axial limiting face is provided with at the welding ends of screwed pipe joint, connecting thread is provided with at the other end of screwed pipe joint, the positioning shaft rank of screwed pipe joint are arranged in the location fit hole in suction tude, axial limiting face is pressed together on the junction plane in positioning step hole and location fit hole, Packed soldered is established between bevel for welding hole and the periphery of screwed pipe joint.
Further, in suction tude, compartment of terrain is provided with 1 ~ 6 group of air outlet hole vertically.
Further, in suction tude, compartment of terrain is provided with 3 groups of air outlet holes vertically.
Further, described soldered is sealedly and fixedly connected with the outer tube wall of bevel for welding hole, suction tude and the periphery of screwed pipe joint simultaneously.
Owing to offering step-like air outlet hole in advance in suction tude, the axis of all air outlet holes is all in same plane, each air outlet hole is by location fit hole, positioning step hole and bevel for welding hole composition, and location fit hole is coaxial with positioning step hole, positioning shaft rank and axial limiting face is provided with at screwed pipe joint welding ends, positioning shaft rank are arranged in location fit hole, the axis of screwed pipe joint is spacing by the junction plane in positioning step hole and location fit hole, Packed soldered is established between bevel for welding hole and the periphery of screwed pipe joint, like this, the axis of all screwed pipe joints can not only be made all to be in same plane, and the axis of all screwed pipe joints and the axes normal of suction tude can be made, arranging of bevel for welding hole can effectively prevent carbon dioxide from producing turbulent phenomenon when welding, can ensure to weld penetration between screwed pipe joint with suction tude, make the welded seam sealing structure that between screwed pipe joint and suction tude, formation three is fixing, seal welding performance can be improved, turn improve the join strength between screwed pipe joint and suction tude, correction shaping is carried out without the need to double thread pipe joint after welding, primary production up-to-standard rate is high.
