Utility model content
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of inflammable gas pipeline and container leak source device for welding with pressure, can with pressurely directly at leak source, carry out soldering, simple, easy to operate.
In order to address the above problem, the utility model is by the following technical solutions: a kind of inflammable gas pipeline and container leak source device for welding with pressure, it is characterized in that: comprise leak source guard shield, leak source guard shield comprises that one makes lasso by fire-proof high-temperature resistant soft material, the upper end open block of lasso has transparent visual baffle plate, is provided with welding rod socket, air inlet, gas outlet on transparent visual baffle plate;
Described welding rod spigot is provided with a circle and has flexible sealing apron, and sealing is fixedly connected with welding rod socket with the excircle of apron, and sealing is less than core diameter with the diameter of bore of apron;
Described air inlet connects one by air inlet pipe and is contained with the non-combustible and container of combustion-supporting gas not;
Described gas outlet connects a visual water-sealed drainage bottle by escape pipe, in visual water-sealed drainage bottle, water is housed, and the mouth of pipe of described escape pipe is arranged in the water of visual water-sealed drainage bottle; On visual water-sealed drainage bottle, be provided with exhaust stack, the bottom mouth of pipe of exhaust stack is positioned at visual water-sealed drainage bottle and is positioned at the top of water, and the top mouth of pipe of exhaust stack is communicated with atmosphere;
Further technical scheme as inflammable gas pipeline and container leak source device for welding with pressure: the upper end open diameter of described lasso is less than lower ending opening diameter.
Further technical scheme as inflammable gas pipeline and container leak source device for welding with pressure: described air inlet pipe, escape pipe are flexible pipe.
The beneficial effects of the utility model are:
(I), by utilizing leak source guard shield leak source to be fastened and passed into non-combustible and combustion-supporting gas not, is isolated from the outside leak source, avoided fuel gas to meet fire and met air after-combustion or blast.
(II) is made into this kind of guard shield, in welding rod stretches into leak source guard shield, can when welding, move, and can see weld by transparent visual baffle plate, conveniently welds and be convenient for changing welding rod.
(III) gas outlet connects visual water-sealed drainage bottle, in order to prevent that atmosphere suck-back from entering in leak source guard shield, and can find out intuitively that guard shield inside is malleation.
Device and method of the present utility model is simple and easy to implement, and does not affect production.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment;
In figure: 1 leak source guard shield, 11 lassos, 12 transparent visual baffle plates, 13 welding rod sockets, 14 air inlets, 15 gas outlets, 16 sealing aprons,
2 air inlet pipe, 3 are contained with the non-combustible and container of combustion-supporting gas not, 4 escape pipes, 5 visual water-sealed drainage bottles, 6 water, 7 exhaust stacks.
The specific embodiment
As shown in Figure 1, this inflammable gas pipeline and container leak source device for welding with pressure, mainly comprise leak source guard shield 1, leak source guard shield 1 comprises that one makes lasso 11 by fire-proof high-temperature resistant soft material, the upper end open block of lasso 11 has transparent visual baffle plate 12, is provided with welding rod socket 13, air inlet 14, gas outlet 15 on transparent visual baffle plate 12.
Described welding rod socket 13 places are provided with a circle and have flexible apron 16 for sealing, and sealing is fixedly connected with welding rod socket 13 with the excircle of apron 16, seal and are less than core diameter with the diameter of bore of apron 16.
Described air inlet 14 connects one by air inlet pipe 2 and is contained with container 3 non-combustible and not combustion-supporting gas.
Described gas outlet 15 connects a visual water-sealed drainage bottle 5 by escape pipe 4, in visual water-sealed drainage bottle 5, water 6 is housed, and the mouth of pipe of described escape pipe 4 is arranged in the water 6 of visual water-sealed drainage bottle 5; On visual water-sealed drainage bottle 5, be provided with exhaust stack 7, the bottom mouth of pipe of exhaust stack 7 is positioned at visual water-sealed drainage bottle 5 and is positioned at the top of water 6, and the top mouth of pipe of exhaust stack 7 is communicated with atmosphere.
