Abstract
The utility model provides a pressure reducing device for novel metal welding and cutting gas. An air inlet joint of the utility model is composed of an air inlet joint pipe 6, a thread hand wheel 7 and a sealing ring 8, wherein, the thread hand wheel 7 is movably sheathed on the air inlet joint pipe 6, an oversize circular ring is arranged on the head part of the air inlet joint pipe 6 for blocking the thread hand wheel 7, and the sealing ring 8 is arranged on the circular ring. The utility model can be well matched with a steel bottle filled with novel metal welding and cutting gas.
Description
The utility model relates to the decompressor of fuel gas decompressor, particularly a kind of welding-cutting gas for metals.
At present, China is combustion gas with acetylene generally to metal material gas cutting, gas welding, is used with post-decompression oxygen after reducing pressure with a special-purpose acetylene gas decompressor during use.The acetylene gas complex manufacturing, power consumption is big, cost is high.Chinese patent application 98113622.2 proposes a kind of safety and energy saving metal welding cutting gas replace ethine gas, and effect is fine.The oil liquefied gas steel cylinder can of this metal welding/cutting gas in use can not be directly with acetylene gas decompressor of the prior art.
The utility model is to propose the decompressor that a kind of suitable welding-cutting gas for metals uses at the problems referred to above.
The utility model is to realize like this.It is made up of high pressure gauge, low-pressure meter, pressure-reducing valve body, decompression screw rod, gas outlet joint, air inlet connections.Air inlet connections is to be made of air inlet connections pipe, screw thread handwheel, sealing ring.Screw thread handwheel kink is on the air inlet connections pipe, and the head of air inlet connections pipe has the garden ring of amplifying to block the screw thread handwheel, and a sealing ring is set on annulus.
The course of work of the present utility model is such.The screw thread of screw thread handwheel is to cooperate with the angle valve of welding gas steel cylinder.When in the screw thread that screw thread is screwed into angle valve, because of the barrier effect of annulus, the head of air inlet connections pipe is entered in the angle valve screw thread mouth, its end face and sealing ring compress on the conical surface in the angle valve screw thread mouth and play sealing function.Opening angle valve regulation decompression screw rod can outwards provide metal welding/cutting gas through decompression by the gas outlet joint.
The utility model is simple in structure, processing ease, well solved the use problem of welding-cutting gas for metals.
With drawings and Examples the utility model is further specified below.
Fig. 1 is the utility model assembling schematic diagram.
Wherein 1-high pressure gauge, 2-low-pressure meter, 3-pressure-reducing valve body, 4-decompression screw rod, 5-gas outlet joint, 6-air inlet connections pipe 7-screw thread handwheel, 8-sealing ring constitute.
The utility model as seen from the figure, it is made up of high pressure gauge (1), low-pressure meter (2), pressure-reducing valve body (3), decompression screw rod (4), gas outlet joint (5), air inlet connections.Air inlet connections is to be made of air inlet connections pipe (6), screw thread handwheel (7), sealing ring (8).Screw thread handwheel (7) kink is on air inlet connections pipe (6), and the head of air inlet connections pipe (6) has the annulus of amplifying to block screw thread handwheel (7), and a sealing ring (8) is set on annulus.
