Background technique
At present, fluid circuit in many machine equipments, as: the metallic hose that is adopted on the Oil, Water, Gas pipeline in locomotive and the rail traffic vehicles is individual layer or double layer construction.The metallic hose of single layer structure has only one deck corrugated stainless steel tubing, and double-deck metallic hose comprises: the corrugated stainless steel tubing of internal layer and outer field stainless steel net.
Though above-mentioned individual layer or double-deck metallic hose are simple in structure, but its crushing resistance is low, wears no resistance, thereby causes pipeline leakage easily, use to the machine equipment brings hidden danger, and then has shortened the working life of machine equipment and environment is caused harmful effect.
The model utility content
The purpose of this utility model is to provide a kind of metallic hose that is used for fluid circuit, and this metallic hose installs the spiral helicine lining pipe of one deck additional between bellows and net, can effectively strengthen its crushing resistance and wear resistance, and the while is simple and reasonable, cost performance is high.
To achieve these goals, the utility model is achieved in that
A kind of metallic hose that is used for fluid circuit comprises internal layer and skin, and internal layer is a bellows, and skin is a net, it is characterized in that: install the spiral helicine lining pipe of one deck between bellows and net additional.
The pipe shaft of described bellows is a corrugated pipe segment, and two pipe end is a straight length, on a pipe end straight length of bellows, be equipped with connect tube head and with the flange welding, on the pipe end straight length of the other end of bellows, spherical joint is housed and nut is housed; Lining pipe is sleeved on the bellows pipe shaft and entangles respectively the connection tube head that is contained on the pipe end straight length of two and the part of spherical joint; Net outside in the corrugated pipe segment of bellows and straight length intermediate location installs sheath additional, an external port of sheath concordant with the port of net and lining pipe and with is connected tube head and spherical joint outer surface and welds and fix.The described anise cover that on the sheath of spherical joint one end, is equipped with.
The utility model is to have increased lining pipe and then formed three-decker on original double-deck basis; can effectively improve the crushing resistance and the wear resistance of metallic hose; thereby avoid metallic hose greatly because of the damaged pipeline leakage that causes; can effectively improve the working life of metallic hose, also protect environment simultaneously.Flange and nut or other Connecting format make metallic hose more convenient and flexible, reliable in the connection of machine equipment, can satisfy the machine equipment, as: the various connections of the Oil, Water, Gas pipeline of locomotive need, particularly there are disalignment, coplanar not at the connection of locomotive (or diesel engine or main transformer) upper pipeline, have angle of swing and under particular surroundings service conditions such as vibration, high temperature, corrosion, have better superiority.
Description of drawings
Fig. 1 is used for the structural representation of the metallic hose of fluid circuit for the utility model.
Among the figure: 1 bellows, 2 lining pipes, 3 nets, 4 spherical joints, 5 connect tube head, 6 sheaths, 7 anistree covers, 8 flanges, 9 nuts.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1: a kind of metallic hose that is used for fluid circuit, comprise internal layer and skin, internal layer is a bellows 1, skin is a net 3, installs the spiral helicine lining pipe 2 of one deck between bellows 1 and net 3 additional.
Bellows 1 is the Stainless Steel Tube with corrugated tube shape of certain softness; Net 3 is a stainless steel braided steel wire pipe; Lining pipe 2 is spiral helicine Stainless Steel Tube.Lining pipe 2 tightly is enclosed within bellows 1 skin; bellows 1 and net 3 are separated; avoid causing that because of the pipeline vibration of locomotive machines such as (or diesel engine or main transformers) equipment the friction between net 3 and the bellows 1 causes bellows 1 breakage; also avoid simultaneously because of net 3 does not possess crowded the breaking of bellows 1 quilt that the external force crushing resistance causes, lining pipe 2 has played a kind of good ductility resistance to compression, wear-resistant protection effect.
The pipe shaft of bellows 1 is a corrugated pipe segment, and two pipe end is a straight length, on a pipe end straight length of bellows, be equipped with connect tube head 5 and with flange 8 welding, spherical joint 4 is housed on the pipe end straight length of the other end of bellows and nut 9 is housed.It is outer and entangle the connection tube head 5 that is contained on the pipe end straight length of two and the part of spherical joint 4 respectively that lining pipe 2 is sleeved on the pipe shaft of bellows 1.A pipe end straight length of bellows 1 pierces into and connects tube head 5 and concordant to port, and this straight length welds together with the concordant with it port that is connected tube head 5; The other end pipe end straight length of bellows 1 pierces into spherical joint 4 and concordant to port, and the port of this straight length and concordant with it spherical joint 4 welds together.This welded structure and method can effectively be avoided producing stress in the weld joint and concentrate.Install sheath 6 respectively additional at the corrugated pipe segment at bellows 1 two ends and net 3 outsides of straight length intermediate location, an external port of sheath 6 concordant with net 3 with the port of lining pipe 2 and be connected tube head 5 and fixedly connected through welding with spherical joint 4 outer surfaces.
Connecting tube head 5 is a kind of pipeline Connecting format with flange 8 welding backs, and spherical joint 4 is another kind of pipeline Connecting format after nut 9 is housed, present embodiment has adopted this two kinds of typical structural types, the Connecting format that also has many other and pipelines equally, as: adopt the oblate spheroid head joint of thread joined structure or inner conical surface joint etc. can satisfy the pipeline connection requirement of various machines equipments flexibly, easily.
When adopting spherical joint 4 that the Connecting format of nut 9 is housed, outside sheath 6, installed anistree cover 7 additional, can more regularly spherical joint 4, bellows 1, lining pipe 2, net 3 be connected to form metallic hose, to strengthen its reliability and stability.
The utility model can effectively improve the crushing resistance and the wear resistance of metallic hose; thereby avoid metallic hose more because of the damaged pipeline leakage that causes of bellows; the structure of its advantages of simple and welding manner have also effectively improved the working life of metallic hose, have also protected environment simultaneously.Metallic hose of the present utility model can satisfy the machine equipment, as: the connection of the Oil, Water, Gas pipeline of locomotive and rail traffic vehicles needs, particularly there are disalignment, coplanar not at the connection of locomotive (or diesel engine or main transformer) upper pipeline, have angle of swing and under particular surroundings service conditions such as vibration, high temperature, corrosion, have better superiority.
