Above-mentioned long lifetime anti-leak oxygen gun cooling water metallic hose, described metal bellows two ends are set with sheath with adapter joint.
On long lifetime anti-leak oxygen gun cooling water metallic hose, be provided with metal net cover outside described metal bellows.
The present invention is directed to problems such as solving short, easy leakage in existing oxygen gun cooling water metallic hose working life to improve, after improving, major advantage of the present invention is as follows: 1, the physical dimension of optimal design metal bellows, improve and make its ductility and intensity, thus make to extend nearly one times the working life of oxygen gun cooling water metallic hose; 2, in oxygen gun cooling water metallic hose, arrange flexible metal entwining tube, reduce current to the impact of bellows and wearing and tearing, water conservancy diversion is respond well; 3, improve the spherical compensator sealing structure being arranged on oxygen gun cooling water metallic hose one end, formed main body sealing structure with graphite note packing course, improve the reliability of sealing, and leakage hidden trouble can be eliminated by the online graphite that adds.The present invention arrives satisfied Expected Results through onsite application.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the I place partial enlarged view of Fig. 1;
Fig. 3 is the structural representation of spherical compensator.
In figure, each list of reference numerals is: 1, spherical compensator, 2, adapter, 3, sheath, 4, metal bellows, 5, metal net cover, 6, metal entwining tube, 7, land, 8, left half shell, 9, shell connecting tube, 10, graphite fills in layer, 11, rubber injecting valve, 12, seal ring, 13, right half shell, 14, bulb tube.
Embodiment
Referring to Fig. 1, Fig. 2, the present invention includes and belong to bellows 4, the two ends of metal bellows are connected with adapter 2 respectively, and the adapter being positioned at one end connects spherical compensator 1, and spherical compensator is used for preventing oxygen gun cooling water metallic hose when moving up and down by torsional deflection.The present invention is directed to the existing problem short for metal bellows working life of oxygen gun cooling water metallic hose and be optimized design: the wave height H of metal bellows is 25.5-26.5 millimeter, pitch of waves B is 25.5-26.5 millimeter, wall thickness is 0.95-1.05 millimeter, caliber D is 300 millimeters, and caliber refers to the internal diameter at metal bellows trough place.The wave height of the metal bellows after improvement and the pitch of waves reduce about 14% compared to existing technology respectively, and wall thickness increases by 20%.Above-mentioned improvement, makes the ductility of metal bellows and intensity be improved, and combines the strict stainless steel impurity content controlling to make metal bellows simultaneously, has increased substantially the working life of metal bellows.
