Abstract
The utility model provides a coupling device for supplying gas blowing pipe which has a certain supply pressure and needs to change gas blowing pipe frequently. The utility model comprises a fastening screw thereon, a gas supplying pipe sleeve and a sealing ring of the round groove therein. The inner diameter of the gas supplying pipe sleeve is greater than the outer diameter of the gas blowing pipe, the sealing ring which is made of soft rubber is installed in the round groove which is arranged in the gas supplying pipe sleeve. The gas blowing pipe is directly inserted into the gas supplying pipe sleeve to sealing through the sealing ring when using. The utility model has the characteristics of good sealing, low using cost and no waste of the gas blowing pipe, etc.
Description
The utility model relates to a kind of for the gassing pipe connection set, be a kind of be used to have certain supply gas pressure, need frequent change gas blow pipe for the gassing pipe connection set.
" a kind of oxygen lance connection set " that utility model patent ZL99233446.2 discloses, its structure is: the oxygen supply pipe and on the oxygen supply pipe box welding of fastening screw arranged and stretch in the oxygen supply pipe box, the oxygen supply tube end is processed into conelet degree conical surface, the circular cone Outside diameter is greater than the internal diameter of oxygen lance, the end diameter internal diameter less than oxygen lance, the oxygen blast pipe box of interior Hole chamfering and oxygen lance welding, the external diameter of oxygen lance is less than the internal diameter of oxygen supply pipe box.Because the connection of this connection set is that sealability is bad, still has a certain amount of gas leakage with the steel bushing sealing; And must be on every oxygen lance welding socket, user cost height, and be welding in enormous quantities by fourth, solder joint often has fracture, causes the oxygen lance waste.
The purpose of this utility model provide a kind of good seal performance, user cost low, do not cause the gas blow pipe waste for the gassing pipe connection set.
A kind of gas blow pipe connection set that supplies that the utility model provides is realized by following approach: fastening screw is arranged on it comprises, in be processed with the air feed pipe box and the seal ring of annular groove, the internal diameter of air feed pipe box is greater than the external diameter of gas blow pipe, the interior annular groove diameter of air feed pipe box equals the external diameter of seal ring, the interior annular groove width of air feed pipe box is equal to or greater than the height of seal ring, seal ring one end that soft rubber is made is designed to " V " font, the other end is designed to the plane, the planar ends internal diameter of seal ring is equal to or greater than the internal diameter of air feed pipe box, the internal diameter of seal ring " V " shape end is less than the external diameter of gas blow pipe, seal ring is installed in the interior annular groove of air supply pipe, and " V " shape end face of seal ring is towards the suction port of air feed pipe box.
The utility model compared with prior art has the following advantages: be connected by the seal ring that " V " shape end face is arranged because of between air feed pipe box and the gas blow pipe, compress through firm screw again, the two side of " V " shape port of seal ring under the effect of air pressure better with the sealing of the outer surface of air supply pipe inner groove wall and gas blow pipe, good airproof performance, air tight, welding socket no longer on the gas blow pipe, cost capable of reducing using also can not cause the waste of gas blow pipe.
Below in conjunction with accompanying drawing mode of execution of the present utility model is described in further detail.
Fig. 1 is a kind of front section view of steam line connection set, also is specification digest accompanying drawing of the present utility model.
Among Fig. 1,1 is fastening screw, and 2 is the air feed pipe box, and 3 is gas blow pipe, and 4 is seal ring.
Fig. 2 is the sectional view of seal ring 4 among Fig. 1.
Described in the utility model a kind of for the gassing pipe connection set by on fastening screw 1 is arranged, in be processed with the air feed pipe box 2 of annular groove and seal ring 4 is formed, the internal diameter of air feed pipe box 2 is greater than the external diameter of gas blow pipe 3, the width of the annular groove of air feed pipe box 2 is equal to or greater than the height of seal ring 4, seal ring 4 one ends that are made into by soft rubber are the plane, the other end is " V " shape structure, the external diameter of seal ring 4 equals the annular groove diameter in the air feed pipe box 2, the internal diameter of seal ring 4 planar ends is equal to or greater than the internal diameter of air feed pipe box 2, and the internal diameter of " V " shape end of seal ring 4 is less than the external diameter of gas blow pipe 3.Seal ring 4 is installed in the annular groove in the air feed pipe box 2, and " V " shape end face of seal ring 4 is towards the suction port of air feed pipe box, and the suction port of air feed pipe box 2 is connected with the source of the gas pipeline.
During use, stretch into gas blow pipe 3 in the air feed pipe box 2 and pass seal ring 4, with fastening screw 1 air feed pipe box 2 and gas blow pipe 3 are connected and fixed again.In pipeline, there is gas stream out-of-date, on " V " of seal ring 4 shape internal face, produce pressure, make the interior outside of seal ring 4 be close to the outer surface of gas blow pipe 3 and the annular groove inwall of air feed pipe box 2, gas just can not leak like this, long as service time, seal ring 4 damages to cause when leaking can in time change seal ring 4.Gas blow pipe does not need to process separately, can directly use.Only need in time to change seal ring 4, gas blow pipe also can normally use.
