Description
Technical field
The utility model relates to interface unit technical field, is specifically related to a kind of novel aviation vacuum elbow.
Background technique
Elbow is the pipe fitting changing pipeline direction.Angularly divide, have 45 ° and 90 ° 180 ° three kinds the most frequently used, also comprise other improper angle elbows such as 60 ° of grades according to requirement of engineering in addition.The material of elbow has cast iron, stainless steel, alloyed steel, malleable cast iron, carbon steel, non-ferrous metal and plastics etc.The mode be connected with pipe has: directly weld (the most frequently used mode) Flange joint, hot-melt adhesive paste, electric smelting connect, be threaded and bayonet joint etc.Can be divided into according to production technology: weld ell, punched bend, push-making angle fitting, casting elbow, butt-welding elbow etc.Other titles: 90 degree of elbows, quarter bend, love and curved etc., if Chinese application number is that CN 202691406 U discloses a kind of novel aviation vacuum elbow, provide a kind of without the need to welding, easy-to-operat, improve pipeline pressure and the novel evacuated elbow preventing from rupturing, but the exact value of the elbow degree of vacuum of this technology can not read, be not easy to control, meanwhile, be also not suitable for using with aviation, have narrow limitation.
Model utility content
The purpose of this utility model is to provide a kind of novel aviation vacuum elbow, to solve the above-mentioned multinomial defect caused in prior art.
A kind of novel aviation vacuum elbow, comprise elbow body, vacuum pump, vacuum box, vacuum gauge and valve, described elbow body outer surface is provided with refractory layer, described elbow body neutral position is connected with a hollow tubular, hollow tubular is provided with valve and vacuum gauge, described hollow tubular is connected with vacuum box, and described vacuum box is connected with vacuum pump.
Preferably, described elbow body is for being 90 ° of elbow structures.
Preferably, described refractory layer material is boron carbide, silicon carbide or boron nitride, and refractory layer thickness is 2-3cm.
Preferably, described hollow tubular is stainless steel siphunculus, is connected on elbow body by welding technique.
Preferably, described valve is the butterfly valve of pressure adjustable.
The invention has the advantages that: elbow body of the present utility model is provided with refractory layer, be adapted to the aviations such as aircraft use, effectively can avoid the damage causing the hot melt of elbow because aviation produces amount of heat and cause, simultaneously, elbow and vacuum box and vacuum pump are connected in series, vacuum box also plays buffer function, vacuum data clearly can be reflected by vacuum gauge, when not needing vacuum, the routine use of elbow can also be realized by throttle down, valve is the butterfly valve of pressure adjustable, not only, outward appearance better appearance, and, operate simple, reasonable in design, applied widely, be worth of widely use.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of novel aviation vacuum elbow described in the utility model.
Fig. 2 is the left view of a kind of novel aviation vacuum elbow described in the utility model.
Wherein: 1-elbow body, 2-refractory layer, 3-vacuum pump, 4-vacuum box, 5-vacuum gauge, 6-valve, 7-hollow tubular.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
As depicted in figs. 1 and 2, a kind of novel aviation vacuum elbow, comprise elbow body 1, vacuum pump 3, vacuum box 4, vacuum gauge 5 and valve 6, described elbow body 1 outer surface is provided with refractory layer 2, described elbow body 1 neutral position is connected with a hollow tubular 7, hollow tubular 7 is provided with valve 6 and vacuum gauge 5, described hollow tubular 7 is connected with vacuum box 4, described vacuum box 4 is connected with vacuum pump 3, elbow body 1 of the present utility model is provided with refractory layer 2, be adapted to the aviations such as aircraft use, effectively can avoid the damage causing the hot melt of elbow because aviation produces amount of heat and cause, simultaneously, elbow and vacuum box 4 and vacuum pump 3 are connected in series, vacuum box 4 also plays buffer function, vacuum data clearly can be reflected by vacuum gauge 5, when not needing vacuum, the routine use of elbow can also be realized by throttle down 6, valve 6 is the butterfly valve of pressure adjustable, not only, outward appearance better appearance, and, operate simple, structure is simple, reasonable in design, applied widely, be worth of widely use.
It should be noted that described valve 6 is the butterfly valve of pressure adjustable, not only, outward appearance better appearance, and, operate simple.
In addition, described refractory layer 2 material is boron carbide, silicon carbide or boron nitride, and refractory layer thickness is 2-3cm, and refractory layer 2 heat-resisting effect of this technology is good, has saved the energy.
Based on above-mentioned, elbow body 1 of the present utility model is provided with refractory layer 2, be adapted to the aviations such as aircraft use, effectively can avoid the damage causing the hot melt of elbow because aviation produces amount of heat and cause, simultaneously, elbow and vacuum box 4 and vacuum pump 3 are connected in series, vacuum box 4 also plays buffer function, vacuum data clearly can be reflected by vacuum gauge 5, when not needing vacuum, the routine use of elbow can also be realized by throttle down 6, valve 6 is the butterfly valve of pressure adjustable, not only, outward appearance better appearance, and, operate simple, reasonable in design, applied widely, be worth of widely use.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
